printing in china | book printing china - Typesetting Before printing should avoid problems

http://www.printing-in-china.cn/shownews.asp?id=1971
In the process of publishing we often meet with some problems, for example: throw words, words displacement and garbled, image distortion, and so on. In fact a lot of problems in the production pay attention can be avoided, here will make some problems that should be paid attention to, and puts forward to for your reference.
1. A lot of people know do typesetting, in the treatment of the words can't choose text bold, and that can make text margin with double (Chinese), if need to use a thick text, should switch to line with thicker font.
2. Choose the font need to use printing songs of the font installed. If it is used in the TURETYPE phototypesetter not installed font, need to be choose to download to use, but OS8.5, OS8.6 system to deal with some problems of the download, sometimes will have lost the problems need to pay attention to stroke.
3. Check before publishing printed in automatic Pagemaker in black, embossing, but some color piece, line will need to do to yourself, Freehand, ¢ó ustrator software such as need to set the printed version of black. For other color printed in software to need to set myself. Pay particular attention to the black edition printing pressure set to check the gray place not printed.
4. ¢ó ustrator software do well directly publishing page slow, sometimes page size will have change, which will save as EPS placement in publishing, faster Pagemaker, but stamping effect, so need not according to the choice of the ways. Publishing page
5. Image in typesetting software had better not spin and cutting, zoom. In typesetting software rotating images will increase publishing yes of calculation and growth publishing time; In typesetting in the software of the images show is thick show, cutting, narrowing the images are not accurate, and the cutting, narrow way to reduce the amount of information, no image can shorten the time publishing; In typesetting software amplified absence made image quality images. So complete image rotation, cutting, zoom in best scanning and image processing software.
6. Hair typesetting process, especially in both Chinese and English, pay attention to the mix row shall not use JiHang and forced JiHang, because this page often made on the screen display the line end have aligned, but the actual output results but have not completed this function.
7. Some RIP in dealing with Pagemaker6.5 software from the 100% 0% of the gradient publishing happen when a very obvious enthusiastically, in Phptoshop gradient image can be added in the home to solve this problem.
8. Some RIP in dealing with the idea of the most large software publishing information TIFF figure errors, so when information is best for EPS format images stored into the publishing again.
9. Use PC platform typesetting software publishing, avoid to use the download font on this problem, the output of the probability is very high, often have the problem, should be in garbled PC platform and RIP the same fonts installed at the same time.
10. Output in PC platform using the WORD software production pages, attention should be paid to the page, page for monochrome because WORD make color of software are RGB mode, page will have certain problems output, even in RIPK color also often error.(Gold Printing Group)

printing in china | book printing china - Printing cost control key is to improve efficiency

http://www.printing-in-china.cn/shownews.asp?id=1969
The mid 1990 s, digital proofing in domestic has just started. At that time, including output devices, and color management software, all sorts of relevant technology are not mature of digital pulls the common people becoming ambivalent. However, make the industry, especially the traditional proofing equipment manufacturers of unexpected is just a few short years, digital proofing already began full before printing market segmentation proofing "cake" traditional printer manufacturers have to stop the traditional proofing equipment manufacturing, completely out of the market. Digital printing, especially digital proofing become domestic before printing trends, such as in the field of arrows, and then what.
Data control superiority
1, use cost
First is the cost of buying equipment. To purchase a set of traditional proofing equipment, in addition to provide and the related bask version, and the print the equipment, skilled workers and a large scale of factory building is also essential. And at present market a high-end inkjet digital proofing equipment, with professional color management software. Its placement cost according to need in 20000 ~ 70000 different wide between yuan. Second, pulls the ultimate goal is to obtain satisfactory results can finally added to the printing and printing processes a. If take traditional proofing and digital proofing, the latter than more shows unique technological advantages. Traditional proofing process complex, and a formal agreement to printing processes, it must first film, to PA version output after the sun beat prototype output tear sheets, once the sample and the needs of the customers when not easy to start again, often can cause more waste materials.
2, the production efficiency
As the name suggests, is a unit of time than the production of benefits. The speed at sampling, compared the digital leaflet print the time needed is basically for 50% of traditional proofing, and the result is more obvious. If the idea, plate burning, printing need time ignored, just pull the traditional characteristic menu type proofing action, leaflet print need an average 30 to 40 minutes. And now in the market a side from the printer, printing speed precision sheet can be controlled in 20 minutes less than.
3, quality comparison
Traditional proofing mode of operation is half manual, output in the amount of ink sample for the control and colour, grasp depends to a great extent on the level of experience and proofing workers. Also is so, traditional play out the sample of the prototype effect is very unstable. According to insiders, the introduction of in the past by traditional proofing, the same set of film take out respectively pull, gain the effect usually is not the same. Digital printing and imaging, because it's so the traditional automation proofing is more stable. Of course, here need to exclude some uncertain factors, such as the print head is stable, whether to need change, or because the frequency forging use not original cause printer ink the phenomenon such as this.
Technical innovation is our scouts who incoming fire has
1, work to do a good job, you will have to have the benefit its device
Digital output equipment and color management software, can saying is the key of digital proofing. How to give full play to the advantages of digital proofing, hardware equipment manufacturers have broad shoulders. In recent years, digital output manufacturers expectations, to break through the bottleneck system technology, whether the printer, or hardware performance color management system, all have improved significantly. To mainstream manufacturers Epson, for example, the research and development of the new through high-tech, launched one of mainly used in commercial printing before printing in the field of digital proofing and high-end image output of the field a printer Epson Stylus Pro 9800 face in colour, the printing speed, reducing imaging stability to have new breakthrough.
2, the stability and the color of the consistency of the reduction
Epson Stylus Pro 9800 eight of the application of color "century rainbow" pigment ink new erp, the "light black", to print ink color accuracy, whether in the image or in detail level, burnish were promotion of the quality. Overall upgrade of gray balance print effect, to eliminate the color distortion, the color transition levels than before a more natural surface of the printer. Epson unique micro piezoelectric and print technology precise control the size of the ink drops in the maximum resolution up to 2880 x 1440 dpi, also can achieve the minimum drops 3.5 slightly litres of excellent print precision and effectively ensure the prints and prints of the sample between color consistency. In inkjet process, the print head need not heating process, so the chemical composition of the ink didn't change, make a single nozzle at work to keep high frequency stability.
3, speed improvement and cost control
A Pro9800 inch wide the print head than the last generation product doubled print nozzle to each color 180, totaling 1440 a nozzle. Increase the print head every time move the printing area, a print a new face rapid standards. In ascension, and at the same time, use the speed motor drive system of high accuracy and position detection system, micro piezoelectric printing technology more precise control inkjet ink drop size, flight direction, avoid incidental residual ink drops. Minimum drops even reached 3.5 rise slightly, the print head and paper every displacement are accurate records, every detail can be accurate performance. Long life design micro piezoelectric the print head, normal use without replacement, save the print head expensive replacement cost, also avoided for repeated the print head calibration and time consuming fee mo.(Gold Printing Group)

Withdraw light agent on the influence of the color

http://www.printing-in-china.cn/shownews.asp?id=1968
Withdraw light agent is a kind of oil cream of shape colorless transparent material, and in the special color printing of main up diluted the role of color. The addition amount from light agent, the influence of different hue is different also, especially the most obvious blue performance.
In the configuration is in the process of color ink, well ink meter, the exhibition ink apparatus to produce the ink shearing force, pressure than the small printing machines. In printing doesn't need to withdraw, but with light agent in ink color swatches make only light agent to join removed, hit even designed the color color display card. In the same color density, color and print showing a color is the color difference exists, it is because the light agent to withdraw, changed the printing ink pigment distribution state, the ink the absorption of light by refraction and reflection are changed, which produce the off color, the color difference is by the differences of the system.
Dry density differences. The influence of the refund
Just printed out the printing, printing ink is still in the wet state, and the dry state has a density difference. Wet color, density is more than dry color density of the phenomenon is called dry density back phenomenon. This is because just printed out the ink layer has certain flow ping sex, so the surface reflection mirror to give priority to, colorful, gloss. When ink layer in dry state, surface diffuse reflection to give priority to, colour and lustre is nature than just printing out appear to be gloomy.
Due to the dry color density in general to finish in Indian dry 30 to 60 minutes later, it can measure to special color density measurement, control more difficult.
With a polarizer device can eliminate the density meter is designed ink layer surface of specular reflection and produce light, and the color of the wet and dry density color density is close, make the measurement of density values from ink layer dry wet effect. For coating paper, measuring density difference of 0.05 ~ 0.15, the coating of measuring density difference paper for 0.1 ~ 0.2. Different color is different also, the yellow color, black is the largest, minimize differences between blue and red between them. So the use of such when measuring the density meter is designed, measured value than the standard shall be the appropriate color sample density value, so that we can play a part of higher control function.
The influence of the system differences
Use well ink meter, the exhibition is the process of making ink color is "dry stamp", and there was no water in the process, and printing is "wet printing" process and wetting liquid participate in process, so in the offset printing ink is bound to happen in oil-in-water emulsions, emulsion of emulsified phenomenon after ink pigment particles in the with the changing of the ink layer distribution state, must produce off color, printed out the product also is gray, not bright-coloured colour and lustre.
In addition, allocate special color of the ink used stability, ink layer thickness, weighing the accuracy, printing ink for the difference between the old and new, printing ink, the printing speed on the amount of the color difference will produce different effects.
Of special color control
To sum up, in order to guarantee of different products, with the color difference conform to the state standards and customer's requirements, we in the printing process to the special color made this control.
1. Color swatches make
First of all the clients according to the standard sample with the color, computer color matching systems are special color ink ratio; To call up with small kind, ink and ink meter, the show is "show" the ink color samples of different density; Then according to the national standard (or to the requirements of customer) color range, with spectrophotometer determine standard, shallow limit, deep limit, making printing standard color card (color difference exceeds bid to be further fixed). Color is half and half are common color sample after surface treatment of color sample, this is for convenient use, such as quality shown the appended drawings.
2. Verify special color
Considering the influence of off color paper is the major factor, so every time before printing with actual printing paper "show" color sample, the comparison color correction, to do the eliminate the influence of the paper.
3. Printing control
The printing machine used standard color printing brought to designed the color layer thickness control, and aided by measuring the density of density meter is designed color value and Bk value, to overcome ink dry, wet color density differences.
In short, in the packaging and printing, causing the cause of special color produce off color various, and should in the actual production of different specific reason analysis, problem solving, as far as possible the deviation control in the least scope, produce customer satisfaction packaging printing quality.(Gold Printing Group)

Small and medium-sized printing enterprise competitive mode by "complete" turn "designed" | Book Printing - Gold Printing Group

http://www.goldprinting.cc/shownews.asp?id=1907
Because of the influence of the external economic environment, the small and medium enterprise is experiencing unprecedented test and printing as entry threshold low, to small and medium enterprises, the industry is experiencing mainly shuffle stage. In such circumstances, how to enhance the competitive power of enterprise, how to get new breakout vitality to become the enterprise management development, which is the most important thing of the most attention must also find a way one of the topics. Difference competitions, is undoubtedly in recent years printing enterprise approved by the most innovative mode. In addition, in the original basis do more "designed", also can become one of the conservative style.
Along with the social division of labor, refined and printing industry competition and more thorough, the perfect competition model can not satisfy need to be competitive, more professional, more refinement of competitive situation has the satellite launch, printing enterprise will maximize the competition advantage reflect pattern also started to spread, outstanding "designed", and "fine" has become one of the development trends in the future.
Hong Kong JinYin group manager WangSheng said in an interview, "designed" more in line with the objective laws of economic growth. The relatively weak and small and medium-sized enterprise must make clear his strongest side where the enterprise, otherwise is not "everything" but "do everything". To the last is not only a single enterprise waste of resources, but also to the whole society, waste of resources. Therefore, the more professional development is the trend of the development of the modern enterprise management, is a enterprise ADAPTS to the fierce competition situation of specialization, seek the development environment of the inevitable choice.
Outstanding "designed" and "fine" to do maximum advantage
Enterprise if can have this kind of "designed" for, to ask the "fine" the idea, so will get the maximum of the relative advantages reflect. WangSheng said, even within the industry is advantage enterprise, in the foreseeable future development will not go deep into all the industry to upstream and downstream, and the development of the enterprise must have the border. For a small printing enterprise is even more so, if you can do all the production process to solve good, also be the ability factors limit. But if from the point of view of specialization, then the different division of labor and positioning of the enterprise, the enterprise has a different resources to maximize to acme, the more will help enterprise better management and survive.
Shenzhen JinHaoYi color printing is shenzhen area and small machinery of packaging and printing enterprise, this company general manager YueSheng said a word: "we only do elegant packing, other are not do, this is our business features." The "special" did it can do that the biggest and did it "fine", not perfection and more management idea is fully explain the importance of "designed".
Shenzhen gold fast India focus on business field, in shenzhen and the surrounding areas become synonymous with high quality. The company's vice President GuoXiaoJie said: "we are more concern was not DuoDa, not buy enterprises have how much equipment, we are more about the enterprise stronger and fine."
Throughout these high quality enterprise, all without exception is outstanding in their professional field. As JinYin group wang manager said, the ability of the enterprise and resources are have boundaries, don't pursue in a business enterprise inside to do all of the labor division, but according to the resources and the ability to determine the total sum where a subdivision field do the most professionals.
"Only after" the "close" is an inevitable way
JinYin group think, sometimes enterprise to "willing" to discard, they are not good at, or even pull its enterprise development, thus liberation managers, link to more energy to the "special" on, to improve efficiency. Is the so-called "good steel used on the edge". The free energy can be used for production management, improve quality and reduce production costs, reduce the energy consumption and create better business, good customer service and consumer service marketing innovation etc, and then their advantage will showcase the strongest side, create the core value.
"Designed" of the benefits will also have to have relatively limitations, BaoTuan cooperation became avoid its limitations of a kind of way. Enterprise and enterprise in common between the spirit of cooperation on the basis of the close relationship between form or as equity associated enterprise of league, or loose such as enterprise and the division of work and coordination between enterprises in the form of the alliance, to 1 + 1 > 2 effect. Not only such, medium and small printing enterprise to withstand risk ability is bad, but also through the form of cooperation enhance its anti-risk ability.

printing in china | book printing china - Digital technology to promote the development of the soft printing

 http://www.printing-in-china.cn/shownews.asp?id=1965
Digital technology in gravure before printing, and application of high performance field of digital gravure printing machine is the constant improvement and development makes the gravure printing folding carton quality can reach the level of the offset printing, and cost is low many.
The application of digital technology, promote the gravure printing technology development, especially in folding carton, carton of drum field gravure printing quite fast development, more and more people have accepted and used to replace paper box, a single mode of production momentum. Soft printing technology in the new breakthrough sleeve new development, in the control network and network expansion rate has a profound meaning, greatly improving the gravure printing quality. The new digital without shaft gravure production line (not always not synchronous belt, axes, and without the introduction of roller gear) to some extent, also promoted the gravure printing quality improvement. At present, flexo folding paper boxes product quality has reached the most basically offset printing corresponding the quality standard of the product.
Market research and results
Recently, someone to the north American 250 household folding carton gravure printing company for a market investigation, the results show that: the leaflet materials processing way will present to decrease: the market share will shrink from 63% in 1990 to 51% in 2000; Drum materials on-line processing (including gravure printing mode and offset printing) would be a great way of growth, market share from 35% in 1990 to 47% in 2000 to expand. Gravure printing market continued to decline in 1990, accounting for 15%, and market share for 2000 years to drop to 10%. The research also shows that: because the gravure printing market share in the 1990 to 2000 these ten years will double (from 8% in 1990 to 16% in extended to 2000), therefore, even if the market share of the drum offset in the 10 years doubled, from 10% to 20%, and the total market share folding carton offset printing is still a descending trend, the will, down from 75% in 1990 to 70% in 2000.
Industry change
Folding carton of European market survey and analysis indicated that the folding carton industry is in a crucial turning point, is from the previous wide, pamphlet, gravure printing and traditional, simple gravure printing, high automation, adaptability to more strong, the production capacity of the higher the narrow without shaft drum soft printing way conversion. Poll, recently, because the introduction and application of flexible digital without shaft rotary die cutting system, set the cutting and creasing, bump trims, etc DuoZhong process in a body, the many working procedure can be a complete, and greatly reduce the production cost.
The early drum folding carton of production line adopts using die cutting equipment, is due to adjust the time machine long, poor stability of reason, production speed is low, cost and efficiency in the leaflet and new hard to type production line to legitimate.
Today's gravure die cutting system is greatly different, performance has improved greatly, and it USES is the rotary type die cutting equipment, width to a maximum of 55 inches (1400 mm), the highest can reach speeds of up to 1200 feet per minute (400 m/min). At the same time, it also has the "rapid change a" device, can quickly change to the cutting of the damage. Some systems also has no gear lifts device, can speed processing complex layers of nested folding carton semi-finished products. On-line rotary type die cutting of another advantage: mold range of options more more widely, especially without shaft mould and surface mold, the price is very low, compared with the traditional short edition box production for the market, single strong competitiveness.
The integration of the paper box within the industry will continue, and industry competition will be more intense. With the new drum folding carton of production line of put into use, will impact the folding carton processing factory and existing folding carton printing houses, there will be some folding carton processing, especially enterprise be eliminated.
Research conclusion
Digital pre-press techniques and digital printing machine technology revolution, will give the gravure printing process to bring new life and vigor, and the application of new technology, will continue to improve, improve the level of production operating performance, therefore, has the very high return on investment sex.
But, for all sorts of different types of drum gravure printing production line, should seriously analyzes its investment amount and production efficiency the contrast between the balance, choose the most suitable performance/price ratio of the equipment, it is very important. The new all-digital drum on-line processing multi-function gravure production line, mostly with rotary cutting device and creasing device or rewinder device, speed, to change a fast, therefore, reduce labor intensity, reduce scrap rate, the production efficiency is improved, more investment value.(Gold Printing Group)

China printing introduced a lot of advanced printing press. The printing press is a high degree of automation, printing speed, product quality good characteristics. But, with the increase of the use fixed number of year, equipment wear and the extent of damage increases, in addition to the natural wear, some parts is due to the operation of equipment conditions caused by the wear and damage to accelerate. If the printer normal maintenance, maintenance cannot proceed, will make the technology of equipment performance, thus reduce down the printing quality. Improve equipment reliability, ensure the quality of printing not decline, production running smoothly and reduce the loss caused by maintain undeserved, these are further explained the printing equipment maintenance is of great importance.
The following equipment maintenance fully explain the importance and necessity of:
1, fuel
In oil production equipment, the lubrication is the equipment maintenance work is an important part of. Keep printing machine oil flow, relates to the activities of the machine parts lubrication. Must be replaced periodically oil and cleaning oil filter device, the oil pipe be into free from oil, avoid part jam. Special is a unit of supporting roller needle bearing, if no oil lubrication cooling, can make the bearings and cylinder shaft long dry friction, wait until abnormalities are found, axes and bearing inner circle have plywood. Light person changing inner circle; The person that weigh of cylinder shaft seriously damaged.
2, mechanical Angle
From mechanical Angle, only equipment operators to strengthen the maintenance, the machine mechanical moving parts clean lubrication, flexible operation, and to bring into full play the technology of equipment performance, keep equipment in good condition. Use of printing machines Heidelberg people know, Heidelberg color printing machine more than the ink forme roller and water roller bearing and the surge is a easy to wear worm, printing ink especially easy to accumulation and its rise and fall in housing agencies and worm seat, especially printing ink crew to the gold and silver, if can't clear in time, time is long, metal particles will accelerate the bearing a worm or wear. Generally the wear of ink forme roller bearing in the walls come down from machine to spend several hours because housing is to use axle gear circle in the rise and fall of fixed institutions, the space is very narrow, only a few centimeters of the loose position, to use reflector to find the ring on block two holes, take out a block housings and reinstall circle and institutions are also very time consuming. Installation of a water roller case also is same. Many different colors offset printing presses, the installation of a worm surge different ways: one kind is fixed a fixed bolts from outgoing machine of the lock wall fixed (more); and [para5] Another is fixed to the wall from machine bolts lock (most use this way), space position narrow, installation, maintenance difficulties. If the staff know this, maintenance, maintain clean at ordinary times frequently, the machine, the accumulation of ink cleared, we don't need to change frequently the bearing and a worm. This can not only reduce down time and improve production efficiency, and can save the replacement of parts cost.
In order to prevent prints the ceng dirty, offset printing machine general use of the spray powder. If the spray powder amount is too big, and can't clear in time word, also can cause some fault, such as the paper automatic lifting devices failure of paper sucking the institutions, slowing damage. Worth mentioning is the offset press paper receiver device of Heidelberg breathe in slow wheel, if axles and breathe in deceleration zone surrounding the spray powder can't keep clear of words, the spray powder and mixture oil sludge, time grew sludge they stick to breathe in the slowdown cannot turn. To protect drive axle of motor, slow turning slow down the agency within the gear was forced to stripping or sweeping teeth. And motor and and education version system circuit fault, once the machine would be stalled. To eliminate the fault will need to be a new gear up. So, usually to clean these agencies, otherwise, the machine can print thick the support role-if, for printing flimsy breathe in slow wheel doesn't work, it will cause paper receiver orgnaization happening disorderly paper phenomenon, reduce the production efficiency.
3, electrical
Heidelberg with many safety device, offset printing machines and are very sensitive, as long as slight touches, all the machine will stop working. Sometimes the electric control box machines internal relay contacts dust pile up too much in, cause relay contacts, touch bad machine can't work.
And many other similar problems, such as motor dust accumulation in too many images of carbon brush frame and reset, and moving images of carbon brush on spring carbon brush compaction force, make carbon brush and copper head poor contact profile, also can cause machine difficult.
4, gas path
In the 80 s produced four color, 5 color offset printing presses are using start device to control roller clutch pressure, ink forme roller, water roller from the ink roll by version and the ink such action. Many of the color printing press each unit has several two five control valves control these actions, through the control valves control cylinder piston sport can realize ink forme roller, water roller on the version and the ink from the ink roll such action. Sometimes, because there were water pump control valve or cause air valve seal, and cause damage control valve or cylinder leakage, makes ink forme roller, water roller by version from well. In addition, the ink in action control agencies accumulation, cause these moving parts not flexible movement, aggravate the control valve and the burden of the pump, lead to control valve seal, the piston pump more vulnerable deformation. In addition, because gas path hose aging, pipe leakage, line pressure to drop quickly, make the control valves can not open, also cannot complete clutch pressure action. If increase pressure, will be the life of the compressor image to further accelerate the aging hose, so only by air valve or the change of air pressure to solve the problem of poor organization rise and fall, not thoroughly, often clean the movements institutions maintain flexibility, guarantee, operation of gas path not leak, not water is in the long run.
All of these problems are usually caused by the maintenance is bad, so to strengthen the maintenance, make daily, weekly and monthly maintenance is very important, it not only can prolong the service life of the machine, also can improve the production efficiency.(Gold Printing Group)

printing in china | book printing china - Printing of the water environmental protection treatment

http://www.printing-in-china.cn/shownews.asp?id=1962
Along with the development of the printing industry, the quality of printing society continuously put forward more and more high demand, from printing equipment, printing materials, printing consumables, to operating personnel operational skills have higher requirements. This paper from the water to offset the quality evaluation, this paper discusses the effect of water quality of the printing and the improvement of water.
1. The quality of the water hardness
When the hardness of calcium, more than 200 PPM can lead to it and printing ink of resin contact form, and in the saponification calcium with acid solution phase at contact, will produce like citric acid calcium and calcium phosphate, of salt.
Saponification calcium has the lipophilic, will lead to ink deposition in the don't need area, such as the water roller, plastic cloth with soft nap, surface water calcium salt have very good hydrophilic, would block the ink transfer and lead to ink roll deinking.
In addition the water calcium if to exceed bid, so will directly affect the service life of the rubber roller, will lead to plastic roller surface crystal.
Conclusion one: excellent water will aggravate the ink emulsifying process, will lead to ink on waterways in the deposition, will aggravate the roller surface crystal) (aging.
2. When the water conductivity fluctuations
Education version fluid dynamic surface tension depends on which education version of the original concentration, the higher the concentration, the bottom surface tension.
Some of the commercialization of automatic conveyer device can control education version of the original concentration, to achieve a predetermined conductivity. When the water conductivity too big when, will cause the concentration of original education version changes, the result is that oil and water imbalance, the trigger fault offset printing.
If the proportion of the original education version, as the other as quantitative and accurate control unit, the problem may not quite, but when the water supply of conductivity change is very big, can still cause of the imbalance between oil and water each role.
Conclusion two: when the water conductivity have volatility, printing process of education version of automation control and testing liquid influence.
3. For many of the factory large companies
Some companies in several cities are factory, needed in order to achieve standardization management is unified quality. To use the same water quality put forward higher request. For example, several cities the hardness of the water itself, a few cities of how water impurity rate how. This is all to have to consider the question.
Conclusion: when three different parts of the water quality at the same time, will not for printed matter of quality standardization produce certain effect.
Through the above analysis, we found that the quality of the water itself, the printing process in a certain range is an influence, so the water and not to deal with the insignificant things, the ability of the enterprise to printing water treatment is necessary, on water quality in bad water treatment is a must.
Water processing methods:
The treatment of water can be said to be DuoZhong channel can be carried out, for example: distillation, softening water treatment, activated carbon filter, micro filter, utrasmall filtering, reverse osmosis filtration and so on.
1. The softening water treatment:
Use sodium chloride gradually after the resin filter to water, when combined with resin has been the sodium ions to meet the water of calcium, magnesium, manganese ions in will be the ion replaced, that is the ion in the water, and at the same time, to calcium, magnesium plasma adsorption to resin.
This treatment can effectively reduce the water hardness (which reduce the water content of calcium magnesium ions), but it is worth bearing in mind is because the water is of the concentration of the ions and did not change, so the water itself of conductivity and not change.
2. Ion to divide
This method is to use cationic resin exchange agent and anion exchange resin agent respectively, the water exchange way ion of Yin and Yang. When the pressure of water through the exchange system, the water of the ion will be resin absorption of hydrogen ions, resin or hydroxyl ions into the water displacement, and also be the resin with charge to consumption. When the resin after failure, can use acid and alkali for reduction of resin.
Using this way water treatment equipment to basically have two kinds:
(1) double bed type resin exchange equipment. This equipment general has two resin containers (Yin and Yang).
(2) mixed. Use the resin using non-ionic Yin and Yang according to certain mixing ratio, use at the same time, if mixed, then deal with proper proportion of the water quality is to get very good.
3. The method:
In normal circumstances, the spread of water from the low concentration to direction of the high concentration of place, the diffusion method is to use certain materials and a means to this process, in reverse pressure to water from the direction of high concentration to low areas of concentration spread. The method is a more thorough impurity removal techniques, be in usually able to remove our drinking water in 90 to 95% of the impurities. More commonly used filter materials: cellulose acetate membrane, polyamide membrane and composite membrane.(Gold Printing Group)

printing in china | book printing china - Double-sided adhesive label printing

http://www.printing-in-china.cn/shownews.asp?id=1959
Now both sides printed label increasingly wide application, especially cosmetics and health products tags. A label on the bottle through the back of the transparent, transparent liquid see the first layer design, greatly enhances the visual impact (such as the petals of the ica, ruby, the second label) design in the back can be directly see, main mark product's simple introduction and company contact method, etc. The traditional process producing such labels very complex and cost is higher, the process is first in transparent self-adhesive materials face capable person on the first floor pattern of the printing, then with the transparent white material (usually PP) composite, again in the white material printing the second design, this eventually produce reversible design effect.
Materials-tags, one pace reachs the designated position
If the company's label Canada ETI would printing, coating, adhesive silicon integrated production line for the production Labeline, it only need in the white face film material (PP) on double-sided printing, besmear again next on silicon rubber attachment can be processed into the non-drying label, the cost to save as much as 65%.
In Labeline on a complete surface sheets can printing, the bottom paper coating, adhesive, silicon compound, die cutting until the finished product label, realizes from raw material to finished product label a forming, the technology greatly reduce the production cost, the label in high-end products such as cosmetic, beverage and personal care products labels have an application prospect.
Labeline the non-drying label is the production line ETI would Cohesio coating machine with the perfect combination of printing machine Metronome, and now the world already in the article nearly 60 production line production. ETI would label Cohesio composite coating production line that the whole of the label's production can in printer factory independently, to change the label of the traditional production technology industry. Stickers enterprise needed to buy some basic raw materials, such as paper/film/silicone oil/glue, in the face of material (printed text or white material) with silicon, adhesive and substrate after compound, processed into finished products. Attachment stickers Since 2000 the first device developed successfully having more than 30 companies buy and put into use. Metronome high precision printing machine is mainly used for flexible edition printing high-grade no end of paper thin film.
A label--first after the birth of the printing composite
Let us see how Labeline for the non-drying label production to provide solutions, a 10 color printing coated compound machine will show how to printing and double label: in two open book separately on a surface material and BOPP, PET substrate materials, dust, first BOPP and two materials after after feeding mechanism, corona into positive 4 color printing BOPP after flipping through a turn on opposite printing. Special design of the flip frame ETI would each part have porosity, film in the process of go in a state of suspension, avoid is always in the process of the transition, particularly applicable to scratch film printing film materials. On the material end before besmear on silicon rubber, and then and good surface composite material printing, and finally die cutting rewinding in equipment, the article points after with devices that can of finished products article points.
In addition to standard UV printing unit, printers can also choose to add LengTang or hot hot device, screen printing unit, gravure color group are offset printing color group, even all the unit can and flexo unit drawer swaps. This computer displays equipment six units use UV ultraviolet (is), but the rest of the dry water-based ink is used for drying were confirmed by IR (infrared). Because Labeline printing in the materials in composite stickers before is a bottomless paper thin film, so the tension control is very important, the tension control can be used in scope from 12 to 300 grams of thin film micron matte. Equipment adopts BST Promark both the alignment system, no matter how the device's speed change, can still keep accurate alignment, save the materials and working time to prepare.
ETI would equipment can easily achieve the non-drying label printing, because in the technological process of the ETI would first printing is again, compared with traditional make stickers off, not only realize the coated process full version color printing (the traditional process is coated in glue 'face printing, printing graphic area of no more than 30%, or glue the viscous will damage. In addition, the printing quality glue could not very elegant), and technology greatly simplified. The specific process for ETI would in no end of paper in the film after printing, besmear again on silicon glue to make the non-drying label printing design, so that in the glue between and material, get effective protection printing, without glazing or coated, the product structure and production cost comparison with the chart 1 shows similar, only white PP membrane into transparent PP film just.(Gold Printing Group)

Curing inks and silk screen | Book Printing - Gold Printing Group

http://www.goldprinting.cc/shownews.asp?id=1898
The bottle container printing, printing belongs to the surface with curved surface screen printers can be completed. And to use nonpolarized PE, pp materials processed into bottle, such as shampoo, bath dew, cosmetics, pesticides and bottles of printing, generally all choose light curing inks, so must have before printing of PE, pp surface treatment can solve the ink in the attached firmly. So, uv-curable ink best cure conditions? What? PE, pp bottle how to deal with to achieve good ink forme polarization effect of this issue, this paper, in the narrative.
A, bottles (plastic PE, pp, pet, prepress processing requirements and) parameters
Now light curing inks are not directly used for did not handle on the bottle of PE, pp, so, want to print a PE, pp, before printing in the bottle must be on PE, pp, otherwise the uv ink polarization processing not firmly attached. So how to polarization processing?
Polarization processing methods have DuoZhong, in PE, pp plastic bottle and its industry by flame treatment method of most, the flame treatment is the result of using the flame contains o, n0, oh and nh etc, it can put the polymer free radicals such as PE, pp etc surface oxygen extracted, then the mechanism by free radicals surface oxidation, and introduces some of polarity of the oxygen groups happen chain reaction, no broken of polarity PE, pp reach to change its surface of polarization wettability, ensure the ink color fastness to adhere.
The water surface tension of 72.5 DaYin/centimeters, oil surface tension for 25 to 50 DaYin/cm.
The parameters of the flame treatment: there are the flame treatment unit most use gas were burning source, should be controlled air: the gas = 7:1 can reach the blue purple flame, then the flame temperature can amount to 1270. C or so, fire control over the length of the inner core 19 mm, flame core top l0 to surface for-15 mm, contact time for l-4 seconds (ldpe for 1-2 seconds, hdpe for 3 to 4 seconds), rotate speed is 100-150 RPM, can be treated surface depth in 40-the 90 a, make PE, pp surface can reach 45 DaYin/centimeters to meet the fastness ink attached.
To PE, pp plastic bottle flame treatment of polarization effect after the test: when the PE, pp, flame treatment after must achieve > 45 DaYin the original surface tension value can ensure that uv ink firmly attached, flame treatment effect testing therefore is very important, its method has DaYin test pen with ethylene glycol + 35% (65%) was a mixture detection and water detection. At present commonly used to detect, soaking flame treatment is the PE, pp bottle submerged in water purification, all will be removed from the water bottle and then pause (about 10 seconds or so) let excess water drop, then watch the bottle is processing parts surface is full of a layer of water film, even if it is full of and continue the close water more than l5 seconds, show the flame treatment has reached the requirements of printing, if the bottle water film discontinuous surface, even if, as the lotus leaf in water, then must adjust the processing parameters to meet the requirements, such as air and gas combustion ratio, and the flame effective ingredients and PE, pp contact time and distance, and so on.
Second, screen printing process parameters
1. In the printing ink, and stir thoroughly before will splashing ink tank filled in on cover all the ink scrape material in stir well.
2. The screen and nets version. Screen: mesh number > 355 mesh/inches of yellow, high strength, low elongation nets. Nets version: tension 18-25 n/cm, with direct photosensitive plasma or capillary film, film thickness 15 to 25 micron.
3. Plastic blow: hardness of 80 ° polyurethane pointed scrape.
4. Nets version cleansing to use common wash nets water.
5. Curing conditions: high pressure mercury vapor, in/wavelength: 280 380 nm in 365 nm, peak is good. Power: 80-120 w/cm or so. Uv curing light speed adjustment: energy requirements.
Three, the plastic bottle printing good uv ink
1. America's solid curing light ink
(1) the PPC series: can silk screen processed PE, pp, and at the same time on the bottle more can be used in pet bottles of free of treatment, can have the effect of high adhesion, high gloss, bear the ink layer, if silk screen amber and other non-ferrous pet bottle, the ink in add hardener, can make the ink adhesion higher.
(2) the pci series: the high gloss, can screen printing already processing PE, pp ink bottle, high adhesion strength, good resistance to water.
2. Germany's curing inks highlights
(1) serit985uv with high gloss and good liquidity, such as add hardener is more chemical resistance, suitable for already processing PE, pp and PVC.
(2) serie988v in different material, have good viscous, liquidity, anti chemical properties, applicable to the already processing PE, pp, PVC, ps and pet, etc.
3. Japan article 10 light curing inks
Rcperg/rcpep-2 (hv) has the flexible, chemicals resistant performance, good adhesion, used for has been treated PE, pp bottle.
4. The French dolby light curing inks
Poiycolor/polyplus series, apply to has been treated PE, pp and pet bottle and high gloss printing ink, has the fine particles uv, high density, color, printing eligibility good and processing PE, pp, good adhesion to enhance water resistance, can add hardener coatings and special of two-component epoxy resin silk screen ink (series 8500), the ink used in glass, metal, spray version processing PE, pp, base material.(Gold Printing Group)

printing in china | book printing china - In 2014 the global digital printing and tag market will reach to 6.8 billion

http://www.printing-in-china.cn/shownews.asp?id=1957
According to the new study, copper and digital printing and packaging and labeling of the global market is expected in 2010 to reach $2.4 billion, the market expanded nearly three times, and the size of the market are expected to total 182% and 23% of the compound annual growth rate health growth, by 2014 is expected to reach nearly $6.8 billion.
According to some early research and expert analysis, in "the digital printing packing prospects in" predicts 2014 five years, in the packaging types, end use market, application and geographical region and the production process can make the global market a recession. In addition, the purpose of this study was to clearly define the from 2009 to 2014 and digital printing and packaging related advantages and disadvantages. The study provides not only for the needs of some key development direction, the detailed introduction of analysis equipment and consumables supplier industry and business opportunities in the pattern of competition is analyzed.
Digital printing before printing and expensive without traditional news typesetting adjustment, which will greatly reduce the cost. Digital printing can not only print in various substrate and ensure the digital printing presses for printing way more than the other functional.
In the packaging and labeling of the field digital printing the main power is short news customization and running of the need to limit dormancy inventories. Should the demand of digital printing labels and packing in the current economic downturn, waste reduction measures is essential, because can use the material, the energy, and ink less and less. The standard digital works file-and the PDF formats like can edit format, Adobe Illustrator, Quark (PDF, Adobeh and Esko Artwork) can not only online, and the receiving in fast fold hands and warning can run after. Therefore, in the past several days in advance to the initial work now one afternoon, this can be done exactly some brand owners pursuit of timely supply chain.
Digital printing can also let converter become 'printing service suppliers', and provide better than the traditional printing business more wide electronic service scope. Customer relationship management (CRM) support, distribution network, and digital photo library management at present all belong to the printer and converter the services provided.
The biggest advantage is the digital printing the variable data printing can do (VDP) and allow a unique product production.
In addition to the other, it can coding and bar code (1 and 2 d), Numbers, included in the integrity of the brand, as well as the different language version equipment limited edition of production.
According to the classification of the industry about digital printing and packaging and labeling of the global market, brand owners by pursuit of innovation and converter for printing speed faster driven by pearl, and expectations in soft line international figures in 2009-14 used during will grow 4 to 5 times. Some of them may be to growth in the past few years has been the slow growth of folding carton expense. In some cases, the brand owners is turning to pure flexible packaging choice.
In the end use market, because of the electronic technology is still in the experimental penetration level is low, food and drinks have among the top. In view of the production of ordinary packaging and labeling, permeability of growth is expected to increase in the near future. According to the prediction of copper and in 2009, the industry in the global sales will produce $6.06 million us dollars, estimated in 2014 will rise to $2.1 billion each year, an increase of 28%.
The study also added a bit, digital printing in packaging market the most common application is production, the emphasis is that even if inspection, prototype, sample and test sets in printing material still dominant, the traditional production function is still the most important. Compared with the packaging, this applies particularly to label equipment consumables. According to pull says, digital pearl general production package and label printing in 2009 is estimated at 93100 yuan in 2014, and is expected to rise to 245 million dollars.(Gold Printing Group)

Manual pulling the operation process | Book Printing - Gold Printing Group

http://www.goldprinting.cc/shownews.asp?id=1896
Manual screen printing homework 1, check the printing plate Check the sealing glue plate, plate for sand holes damaged, and without loose floor plate installation, nets from proper positioning is correct, printing rules, many have go f version phenomenon. 2, the selection of scraper The length of blade should be slightly longer than printing, printing and different things should choose different shapes of scraper. Rubber spatula due and certain flexible, and improve nets edition with things contact performance, printing ink even. Scraper mouth, such as not smooth level required to wear away, application sand paper scraper materials can choose 5 mm of acid rubber production. 3, printed material preparation Seal material shall be according to the preparation of the printed material and things to decide exactly the type of printing and composition, allocate key is the palette, when dry degree, the viscosity, makes every effort to adapt to the requirements of the blow seal. Seal material shall first be tuned and deposit a day, make its stable performance, and the golden except. Should also look at whether foreign body in print material, in case the blow when printed cut the board. 4, printed material. Cast Printed material generally fall in net frame ahead in the starting position and scraper, within the scope of width in the box seal material shall not net place too much, be added any time, and scraping the seal operation easy control of ink. 5, scraping the seal (1) put things in handheld prints with the rules of the counter and put down the nets version, the printing plate and frame with certain nets between blocks away from. (2) the handheld scraper pressure to screen, scraper scraping the move should maintain a 50-60 ° Angle, with a certain speed scraper for scraping the ink campaign to make materials in squeegee pressure seal, the function of hollow out graphic part of the screen from the hole in the LouYin to the thing on printing, scraper scraping the screen printing and rebound after things apart. Depending on the size of the printing area and the length of scraper, can adopt single hand or hands, but to blow seal operation control the amount of material printing, the printing plate layout to scraper, can not have the seal material in the plate and place. (3) to carry the tennis box, from the counter take out their content. 6, scrub nets version The printing process, found imprinting fuzzy and nets hole clogged, be scrubbed the printing plate, with skimmed cotton wool or soft cloth dips in solvent graze nets version, when both sides swab shall first scrub graphic place, then scrub other place. Both sides of the plate to scrub clean, plugging nets place to relax and blot on the plate of the solvent. After the completion of the printing plate should also will be swabbed clean. 7, precise color printing Used for the precise color printing color version blow to distinguish the ink levels, in general should first printing light color printing, first YinCi after dark to India, in the system after the main plate should be arranged when. Precise color version must be accurate, especially the first longitudinal monochromatic edition rules to India is very accurate. In the scratch of mixture color printing, should inspect mixture color to the plate on the form change, for the print edition scrape. 8, printing, dry Every time after printing to dry, but two colors in the middle of the dry only request road printing won’t contamination on the road print, the last of the dry also consider the ink layer dry, in order to ensure that the ink layer attached fastness. Some prints for climate change things easily expand and contract, such as overprint, long time not in time aside, this will cause misregister in dry, attention should be. (Gold Printing Group)

printing in china | book printing china - Version roller transportation and keeping the new method

http://www.printing-in-china.cn/shownews.asp?id=1955
Printing plate
1, and websites: network composed of printing design is a minimum unit. Gravure outlets the different ways of making due, version roller on the site also reflects have differences: electric carved with nets into carving outlets, the change of the size of the network and depth has followed the change; Coating corrosion network with the change, only a net in dot size change; Laser version of the change of the different nets into outlets general displays in network depth.
2, the color of the light source object: color. Nature, most of the object itself is not a shimmering, such as print, flowers and plants, trees. They are the colors of the spectrum of the sun from the colored light to reflect or transmit the. In the nature of light color is red, green, blue, these 3 kinds of color of different combinations can form hundreds of colored light; Pigment primary colors is green and yellow, magenta, in theory, the three color pigment different proportions of mixing, can get all the color in nature.
3, hard blow and blow: gravure printing soft in the different scraper in printing outfit law the effect of is not of appearance. Hard blow off the support scraper blade is to point to a short, the effect contrast big, easy to wear version roller, to solve the page will have little effect not clean. Soft wind is refers to the scraper blade from a long distance support point, the effect is tonal gently, easy to produce HuiWu. For tablets of the part of the shallow network transfer will be to some.
Version roller transportation and keeping:
Version roller transportation to the protective measures, such as in the version roller surface layer of thick bag, avoid corrugated paper in the transport of collision and turbulence.
Version roller in printing to clean, above all after the residual ink in version roller will cause off chromium and plugging version. And then in the version roller coated with even on temporary, with quality of a material soft paper (also can use waste printed samples) will cover the, and store in a cool, dry place can.
Special attention should be paid to a bit, the place to stay away from acidic substances.
Gravure version roller maintenance guide
Gravure version roller surface of chromium layer in the meet acid, alkali etc corrosive liquid, gas or unqualified solvent, will quickly be corrosion, on the screen form small point, printing, printing film in the transfer out. This phenomenon in damp environment to occur, because the moisture in the air is very easy to absorb acidic or alkaline gas, and air and version roller surface in contact at any time. In the chromium layer has just been corrosion, if not refund chromium plating as soon as possible, can be very heavy in not long time to copper corrosion in layer, make version roller scrap, cause needless loss.
In order to effectively avoid above phenomenon, my company through various research, now offers a kind of save version roller method, for the use of reference:
1. In a YinCi finish, the version roller with solvent clean;
2. Use clean soft cloth to wipe, layout don't leave fingerprint (for fingerprint contains sweat corrosion ingredients);
3. Dip in with soft cloth take clean low volatile oil, light in version roller surface evenly with a layer of, careful not to use spent oil.(Gold Printing Group)

First of all, your wireless to print the server will also compatible with wireless networks and printers, if your printer manual no specific mention and no line to print the server compatibility, don't be discouraged, some printers use manual and did not mention is the printer and print servers compatible, but, when using you will find that, in fact, be compatible.
Usually, you can go through the Internet inquires the printer compatibility, in a printer server vendors's official website, usually have some related information, to help you to identify compatible devices. Through the wireless to print the server, can realize the wireless printing purpose, but if you use a multi-function equipment, through the wireless server is not realize scanning and other functions.

printing in china | book printing china--Water-based ink printing corrugated paper of four ways

At present corrugated carton industry use water-based ink printing equipment has four kinds of production methods, their characteristics different from each other.
One is LianTiaoShi single printing mode, this kind of means can only printing, no slot and die cutting.
2 it is generally use the printing press round and round the production of die cutting way, the way and the ink printing, the slot or die cutting, only after adhesive (box) can nail shape.
Three is to use fully automatic printing and slotting, fold the bonding (nail box) mode of production, the machine for folding forming and adopt ink printing system, is on a one-time molding machine.
The fourth is a advanced printing, round flatten die cutting way, it is the feature of multiple color printing equipment can be, high accuracy, printing products can reach color printing effect, especially suitable for color box sales packing. The above several production mode, its common feature is the ink printing, printing principle and equipment structure basic same, just how much color, include line number and process equipment different ways. The printing process by many factors and the influence and restriction, a lot of problems is not by operators on simple and adjustment can be solved. Only through the synergy, try to reduce and avoid during production in some of the unnecessary problems.
Gold Printing Group will to ink printing or frequently of common problems are analyzed, and corresponding take the necessary measures.
1. Slotting knife and longitudinal line pressing size, not produce printing position is not accurate
Cause analysis: as the slot, not according to your drawings and line pressing process of size adjustment, cause cardboard length or width size deviation, finally affect manufacture printing position no.
Solution: first should be according to the drawing size adjustment manufacturing slot or line pressing size, requirements, and then according to accurate position accurate position to adjust the size of the plate position, check the slot or line wheel wear generated by the deviation.
2. Row system, causing no print position of the plate to adjust
Cause analysis: because local f and plate position shown not clear, layout much error when, in the actual production of printing position is obvious causes deviation. The printing equipment basic is printing, publishing and cylinder is in the plane, inevitable meeting produces vertical position errors, and because of the size of the printing pressure has shrinkage rate problem.
Solution: first in making 1:1 ink figure, should according to normal percentage of shrinkage rate draw. In typesetting strictly according to the ink figure position adjustment print. In the precise color accuracy, high should be used "graticule marker" typesetting method, with the figure of the plate and, when necessary, to is graticule marker used a magnifying glass check deviation.
3. Printing double and leakage problem. White
Cause analysis: this two problems in the process of production is often appear. Printing designs or words appear around double, because anilox roll and the pressure plate cause; Printed in the front edge of the double, it is because of the printing roller and embossing roll the stress caused between. Large size printing, the leakage white is interlocked with pressure seal because printing roll roller pressure produced enough. The two problems is the opposite of the pressure creates.
Solution: printing double problem shall be adjusted anilox roll and version roller clearances between pressure and pressure, commonly known as on. Double is because stress, roller extruding print (flexible edition) refers to the deformation, so to increase the two roller clearance less pressure. Printing leak white problem should be adjusted version roller and embossing roll gap between pressure and under pressure, commonly known as. Because version roller and embossing roll gap is too big, large area produce false in printing, it needs to be under increasing pressure. Another print not smooth, edition line, the printing plate hardness, etc will influence the quality of the problem, should carry out the local adjust.
4. Many color printing misregister
Cause analysis: misregister problem in printing industry is universal, because it is various factors, solve up is not very easy thing. First many color printing machine itself version roller and location of the accuracy of precision is direct factors. Second is the paper roll, drawing roller adjusted, traction with use, the accuracy of the arrangement of plate, and cardboard warping problem all can produce misregister problem.

Flush type folding of the pros and cons | Book Printing - Gold Printing Group

http://www.goldprinting.cc/shownews.asp?id=1892
The newspaper has two kinds of different offset presses the principle of the way of the cross breaks, a kind of impact type folding, for a splint type folding. Due to the impact type folding of simple structure, convenient adjustment, and was widely used offset presses newspaper. Although the impact of also has the edge when machine operation speed change, newspaper products, the folding seam will change position, especially when the newspaper printing ink amount was more susceptible to folding clip roller, but for embossing disadvantages such as quality requirements for the newspaper is not very high, as long as the problem is not very serious, the impact of these shortcomings of folding machine completely will be the advantages that cover.
The working process of the folding impact type are as follows:
(1) printed by the SanJiaoBan longitudinal fold paper tape, after the guide roller and pull through paper roller, be on the edge roller pick needle hook;
(2) the tape in cutting knife edge roller pads and cutting roller cutting knife, serrated between through cutting knife cut it into sheet;
(3) of the roller folding planet folding knives will insert a folding clip newspaper between rollers complete cross breaks;
(4) fold the good newspaper clips from folding between rollers, and then fall into wing round was sent to the conveyor belt.
To use good impact type folding machine, the key is to do well, but the adjustment of the roller folding it is difficult to grasp. Here in Japan gaussian impact type folding machine as an example, the paper introduces the do.
1. Folding roller and cutting roller the relative position of the adjustment
In the assembly, the cutting knife edge roller pads should and cutting the roller zigzag cutting knife is right. Folding roller and cutting roller composed by a mesh with each other's gear transmission, cutting roller and transmission gears for key links, folding roller and transmission gears for long bore screw connection, change and screw holes of long connection position, can achieve edge roller gear and adjust the relative positions of the goal. The trace of the adjustment by changing the pick pinhole and cutting machine distance to achieve, but in practice do not advocate adjustment here.
2. Pick the needle of adjustment
Pick the expansion of actions by the needle transmission of CAM control, pick the adjustable needle trip by CAM mechanism, but decided to pick out each needle roller surface edge of height can adjust alone. In order to guarantee the needle to withdraw completely pick edge roller internal, pick out needle roller surface folding the height of less than pick adjustable needle should schedule. Measuring needle height to pick out the folding roller turned to pick out the needle, the largest amount to pick out the needle roller surface height 6 mm brochures for standard. In practical production according to the different thickness of the folding dose of the request, can fine-tune pick out of height. Needle
In the folding process, pick the needle is stretched out in advance, with the rotation of the drum folding, stretch out selective pins to plunge into the paper tape, so pick out the moment does not require needle very accurate, when adjustment in May not have to consider pick out of the needle moment. But when folding knife will insert folding clip roller newspaper, pick the needle in time, i.e., pick to retract needle of indents moment must be accurate, otherwise the indented too party for folding knives and tear out paper, indentation too early and to make paper tape for some time out of control, influence accuracy. Folding In addition, pick the needle indented process should also rapidly, make needle and planetary folding knives pick the action coordination. Loosen the adjustment on the transmission pick needle, or if the CAM tighten the screws indented too early would make pick the folding of roller CAM needle is turn mobile, and indent too late and will make the folding roller CAM pick needle the reversal of the direction.
3. Folding knives high adjustment
Folding knives of spindle is by folding roller operation gear do the movement of the planets, such folding knives axis rotation, and both the revolution. Folding knives rotation and transmission ratio of the revolution in the sun and planets wheel gear wheel of the relation said. Because folding knives rotation is actually planets wheel rotation, and folding knives revolution is the rotation of the drum folding, so that each turn, a week folding roller folding knives were put out three times, three phase difference is 120 °, only down the stretch out a, just to folding clip roll into so as to complete for middle cross breaks action.(Gold Printing Group)
