The quality of plate production and production of all kinds of temperature of the relevant. This temperature include: 1, operating room temperature; 2, the temperature in the oven; 3, exposure the temperature in the cabinet; 4, developer temperature.
1, operation indoor temperature
Operating room temperature should be generally keep in 25 ¡æ or so is advisable. Winter and summer season should pay attention to the temperature adjustment and control.
For F edition terms, the influence of the room temperature is not clear.
For D version and a team in the hot weather, if the room temperature control is bad, will produce the following questions:
(1) the preparation glue easily to have hot crosslinking, causes the enhancement difficulties or does not show the;
(2) the liquid glue, which produce the large amount of bubbles layout have bubbles or sand holes.
For N version will tell, room temperature less than 2 O ¡æ, it will produce the following questions:
(1) the blow caused by uneven thickness glue enhancement difficulties or does not show the:
(2) the layout, cause printing appear sand holes in the process of slurry leakage phenomenon;
(3) the layout is uneven, cause printing grain colour and lustre abhorrent.
2, the temperature in the oven
According to their performance index plate material set the drying temperature, should adjust measures to local conditions specified range from the lower limit of trial began gradually, choose the best drying temperature. General drying N version does not add drum wind; Drying F or D version is to add drum wind, so as to speed up the layout of speed, good water volatile as dry layout.
Drying temperature is too high, it may produce the following questions:
(1) the development, produce have difficulty "; Or does not show the;
(2) the screen loses flexibility, the printing of the motifs distortion.
Drying temperature is too low, the drying time is extended, or paper necessary layout can not be fully dry. Will tell to F, D version will cause when membrane layer or enhancement after falls off phenomenon; To N version speaking, when the easy also developed after thinning, shortened thereby the service life of the plate.
3 exposure, the temperature in the cabinet
The temperature and extremely easily ignored. Often drying temperature master better, and because the temperature in the cabinet of the ring, exposure will ultimately give plate making failure.
The temperature in the cabinet depends on the light exposure species. If belong to cold light source, general can not be considered; If the light source is stronger, for solar heat high-pressure mercury lamp and so on, should be special attention. Because of high-pressure mercury lamp can't, so usually adopt moment lit a few version of continuous exposure method. In this way, it can make the exposure plate surface temperatures as high as 85 ¡æ above. The temperature on F, D, N three layout is very bad, and it will produce and due to high temperature in the oven and cause enhancement and similar problems difficult, serious impact on the quality of the plate. Therefore, it must be in the air exhaust equipment installation exposure, and to decrease the plate surface temperatures. Generally speaking, the printing plate surface temperature cannot exceed drying temperature.
4, developer temperature
Imaging: is making in the success or failure of the printing plate last condition. When the first working procedure, developed by careless operation difficulty or does not show the, also often take increase the developer temperature method to speed up the development speed. Developer temperature should pay attention to control, common should with drying temperature for upper limit.
If the developer temperature is too high, appear easily to the following questions:
To F, D version speaking, easy to cause the swelling, decorative pattern around layout produces jagged;
Will tell to N version, make easily motifs edge be afraid, produce motifs deformation phenomenon.

Nets printing use water-based ink in the problems | Book Printing - Gold Printing Group.
http://www.goldprinting.cc/shownews.asp?id=1916
1. In the nets printing, attention should be paid to control the water-soluble ink parameters, including ink viscosity, liquidity, thixotropy and plasticity, etc.
2. Note the water-soluble ink control index. The water-soluble ink control indicators are mainly fineness and viscosity, pH value and the drying speed, etc, they to the ink and application effect of the decisive role.
3. Because of water-based ink to pure water system, so pay attention not to use of the water-based ink and alcohol sex ink and solvent ink used in ink or mixed in organic solvent, lest appear printing quality problems.
4. Use water-based ink, should its stir well, measuring viscosity suitable ink slot into, if not suitable viscosity, can use thinner or thickening agent on the adjustment, and pay attention to control ink pH value, general master in 8.5 ~ 9.5. The printing process, because the volatilization of water, wash viscosity increases, pH value falls, so always observe the ink use situation, found that the ink viscosity rise or pH beyond control range, should be adopted timely thinner and pH stabilizers on the adjustment, in order to ensure that the viscosity and pH value stability.
5. Usually, very suitable for high speed printing ink printing, low speed if meet the drying speed too fast or printing the effect not beautiful, can add a certain proportion of slow dry agent.
6. After the printing ink painting should be the remaining original barrel or take corresponding will ink tank cover tightly with the lid of the stores of time, used again. Because the surface to prevent ink conjunctiva, thickened and even become dry. Should be stored in a cool and water-based ink ventilation of indoor, room temperature control in 5 ~ 45 ℃.
7. After printing residue in the ink printing equipment in its not completely dry available, can't rinse rinse of the ink can be used for cleaning cleaning agents.
8. The ink printing eligibility by printing conditions, their surfaces properties, environmental temperature and humidity, the storage time length etc. The influence of the objective conditions, so when use, need to use some additives on ink painting do fine adjustment to get the best printing effect. Water-based ink of auxiliaries used in nonferrous materials, pH value stabilizers, slow dry agent, defoaming agent, dilute agent, printing auxiliaries to be familiar with the characteristics and method of use.
1) color material used to deepen its dosage should be color, general control in 0 ~ 30%, more than 30% will be making the ink connect material content is too low, lead to the adhesion and abrasion resistance down.
2) pH value stabilizers is used to regulate and control the water-soluble ink pH value, make its stability in 8.0 ~ 9.5, ensure water-based ink printing state. At the same time, it also can adjust the water-soluble ink viscosity, and the ink to dilute.
3) slow dry agent used to reduce the dry degree of ink, slow dry agent can inhibit water-based ink and slow the drying speed, prevent ink printing plate in the dry, reduce the blocking version and paste version and printing of failure. Slow dry the dosage of the general agent should be controlled in total amount of 0 ~ 10% ink, if addition amount, not too much ink dry thoroughly, prints will stick dirty or produce peculiar smell.
4) dilute agent used to reduce main depth of color, the dosage is not limited. But to join a lot dilute agent could lead to ink painting viscosity risen slightly, then can also add a little thinner adjusted.
5) to dilute the main used to reduce the dosage of viscosity, ink painting should be controlled in 3% less than, just not reduce the ink color depth, and keep the ink painting pH value remains the same. Thinner should be stirring slowly add edge in low viscosity. If join more thinner or use high hardness of tap water dilute will have bubbles, then should join defoaming agent.
6) use water-based ink appear in foam problem is the main cause of the water as a thinner in emulsion polymerization, when he must use a certain number of emulsifier, make the emulsion system surface tension dramatically reduced. Defoaming agent's role is to suppress and eliminate the generation of bubbles, and avoid have bubbles and appear pinhole, leakage white, nonuniformity ink printing quality problem, but generally defoaming agent to control the amount of between 0.1% and 0.2%.
7) thickener mainly used to increase the viscosity, ink and can give ink excellent mechanical and physical and chemical stability in printing, can control the role of rheological properties, but not too much, if the amount of water-based ink using too many thickener, can make the bubble film wall thickening and increase the elasticity, make the bubble is not easy to eliminate, general control in 0.5% ~ 1% for good.
8) fast drying agent mainly used to speed up the drying speed, the dosage ink painting is 0 ~ 30%.
9) the subsidence agent can make the ink pigment particles suspended even and not easy to rally settlement, avoid to produce float color phenomenon.
The trend of the development of future water-based ink
Because has the water-based ink good environmental protection characteristics, at present developed countries and regions are working to develop and use water-based ink to gradually replace ink solvent. With water-based ink printing as the main development object of packaging and printing international had formed a kind of trend. From the international packaging printing, the development trend of water-based ink has set up a file from a single box to all kinds of base material, more ink printing development f.
In the United States and some European countries have banned the use of ink solvent contain benzene, instead of green environmental printing ink. Now, the plastic printing in 40% of the water-base printing ink. Other developed countries, such as Japan, Germany, France, etc, in plastic film printing also more and more use water-based ink, Britain has legislation to ban the use of food packaging printing ink solvent with film. In recent years, our country for food packaging also made some regulation, water-based ink printing position in China is constantly improving.(Gold Printing Group)

printing in china | book printing china - Fabric printing the common way
http://www.printing-in-china.cn/shownews.asp?id=1975
Fabric printing refers to fabric printing method in the process of forming pattern. The printing methods are: type edition printing, screen printing, printing, cylinder round nets of transfer printed and multiple color printing dyeing methods in, of which comes from the screen printing type printing (including a grown-up version of XinBan), from the start of and manual operation, step by step, fully automatic, semi-automatic and later peace nets type development to circle the net type.
Fabric printing generally have several printing mode:
1. The coating printing directly
Coating is the direct printing a good printing paste printed fabric, directly in the printing process is the most simple and common use process. Coating printing technology directly generally means in white or light color printing fabric, convenient for color it together, simple technology, after the deal with roasted printing can, it is applicable for various fiber textiles. Coating printing process according to the current directly that often USES adhesive can be divided into the Accra Ming F type adhesives. Acrylate adhesives, butyl benzene latex and chitin adhesives three direct printing technology.
2. Silk printing
Silk printing the main methods of discharge YinHuaFa YinHuaFa, direct, and YinHuaFa dye. YinHuaFa directly in front of, have introduced YinHuaFa discharge and transfer YinHuaFa, penetration YinHuaFa will be behind the section of a separate, here basically introduces the YinHuaFa dye.
3. Knitting underwear printing
Knitting underwear printing main application coating printing technology, fabric printing directly after The Times or natural drying can, to avoid the knitted fabric wet process easily and agriculture wet processing difficulty. Printing method to flat screen printing is given priority to, and divided into the net by printing machine operation and scraping in two ways. The printing method can adapt to the constitution form and organization structure designs, and suitable for small batch production need more design and color.
4. Discharge printing
Discharge printing and printing, with carved says to discharge agents in non-ferrous fabric, printed on the part of the pigment has dyeing disrupted, and obtain a variety of decorative pattern, pattern of the YinHuaFa. Discharge agents is the color of the dyeing away a chemical. Crane white never, ferrie sulfate-potassium thiosulfate, etc. This method can divide a decorative pattern is white (white) and decorative pattern for non-ferrous (printed) pull out two. After a RanFa make fabric pattern, but process, fine complex high cost.
5. Printing sodden flower
The use of two kind of sodden flower with different acid proof of fiber blended fabric, after acid sodden flower plasma printing and chemical processing, will not acid natural fiber part, showing the rotten to chemical fiber, part acid formation of glittering and translucent and transparent pattern, its special style made sodden flower product has the feeling of high-grade flowery. Sodden flower products not only beautiful appearance, inner quality, have wear-resisting, high strength, good washing and drying quickly, iron free performance by domestic and foreign market, welcome. Sodden flower technology research and application in recent years popular in textile dyimgs.
6. Wool fabric printing
At present, the printing wool fabric with thin tabby fabrics or gauze fabrics is given priority to, most used to make women's shirt, dress, be towels and skirt. Wool fabric printing in the direct printing outside, still pull the printing and printing, printing of transfer. MaoHunFang fabric printing and proportion, at present, wool fabric finishing also quite popular with, mainly for the CuFang sweater.
7. Velveteen printing
Using the characteristics of silk screen printing diamond in velveteen on printing can obtain a special kind of flash effect, in sun exposure can send a natural diamond under general ray of light.
8. Foaming printing
Special printing fabric various products, foaming printing is a kind among them. Foam printing features are: stereo sense is strong, similar to artificial embroidery, feel soft, wear resistance, resistance to water, good color fastness, flexible, and can be widely used in table cloth, curtain, tea towels, handkerchief, pillow towel, clothing, souvenirs, etc. It can not only in such as cotton, hemp, silk on natural fibre fabrics, but also can be used in artificial fiber fabric applications.
9. Flocking printing
Electrostatic flocking is the textile industry are on the rise of new technology. It is the use of high pressure electrostatic field in plant short fiber cloth top of a product. Flocking products simple process, stereo sense is strong, low cost, and it is widely used in rubber, plastic, leather, decoration products, especially for small batch of tourism products more show it extremely superiority. In the shoes and hats, children's clothing, trademark, the dress with flocking design adornment, can make its features a unique style.
10. Transfer printing
Transfer printing is the sublimation of the dyes on the fiber with steam and dye diffusion and the role of affinity to finish coloring effects of a printing technology.
Transfer printing is without water processing in more meaningful to a kind of printing and dyeing production methods. In addition to not water outside, still a main characteristic is paper, so little deformation can be printed fine multi-level pattern and photography pictures. The pattern is the real picture transfer to cloth. Its effect is sometimes the discharge printing, than generally better.
In addition to the above ten kinds of common printing way outside, still have some special printing methods such as: electrochemical aluminum transfer printing, printing, fluorescent light electroluminescent printing, gold, silver, coatings, printing color printing, printing foam fragrance, diamond printing and printing printing and so on, printing bead light way.(Gold Printing Group)

printing in china | book printing china - Reduce the printing off color
http://www.printing-in-china.cn/shownews.asp?id=1974
Today in the BBS see on paper. The effect is using digital proofing, proofing manufacturers behind modifying only a text file, the manufacturer USES ordinary printer color out a, that guest sign. The results come out color printing off color. The payment for goods has paid off all the guests. Q do?
Yesterday we printing a beer TaiKa propaganda. The customer the design of your own (and old customers). And in JinYin straight out to print one, with 157 grams of double copper straight out, color is bright beautiful. Order entry, the requirements of the guests with 250 grams of single copper, TaiKa sure to put in on the table.
Order entry, already say with less than, the customer not afraid, color printing it. The goods time too late.
The printing process, beer bottles of red always not enough red, the rest of the local red too hard. The difference is too big, can't print. Customers drive to plant, color said personally seen again so, making too late. As far as possible will increase, a little red blue a little bit small.
That such off color why the difference, so why the big?
Reasons are as follows
1 the digital straight proofing, printing, using 157 grams of double copper, and file the customer has changed. Many customers said documents when I was a little shrinkage or change the file. But sometimes they have no intention of reform. But the new documents have pull, direct the film printing. So this time off color is bigger, also is one of the main sources of off color
How to avoid it?
1, as long as the document revision, must pull. If color is demanding, best yes, with what kind play traditional paper printing, use what paper to pull. Do the uniformly, so will off color plugging in the source. Especially new customers have to do so. Digital sample line not? Line. But also does not have a traditional kind. Digital proofing must be in manufacturers there dozen, general manufacturers have CTP. Digital printing machine and the parameters of the move into a to playing like this, out of the digital kind, printing and color can reach more than 9 into. Unfortunately, many CTP printing manufacturers, not tuned to a printing press parameters, or not.
2, the design problems, a lot of stylist doesn't understand printing or know some of the printing, not professional design, so out of the file looks very good, it's hard to do. Like many designers will be made when black C, M, Y, K100 % field, the longitudinal glancing to printing, yes this black is very nice and printing? Increase the difficulty, so big ink amount, it's hard to control. Especially, due to the large amount of ink flimsy, difficult to control ink printing paper, balance, it's hard to go walk good, often stop. This color which have no deviation, all the way out of the printing, and all the way off color. And four color into the flat out only one color nets, no control, color difference is bigger.
How to do, to avoid it?
To demand higher color piece to special color printing ink, especially in large quantity or flat nets color piece. If big ink amount can't to special color printing, in big blocks of colour don't do small font or picture line, to increase. The more can't make four-color printing, anyhow method is there
3, process press the row be reasonable, in rows before the project, single single, the process by a row
4, color, the captain of the main sources for improper operation.
Now more and more advanced, the captain for printing the requirements of printers requirements before many not so high. Many of the control for the captain color is very poor. In ink painting not under the premise of balance, with a few pieces of printing color sample, close to the printed, all the way down the paper went to bed at all, adjust the ink amount, all the way off color. Where there is no off color.
So printing color difference is inevitable, but too much deviation of off color can avoid.(Gold Printing Group)

Roller of glazing: the roller of coating device will be transferred to the oil light box surface. The glazing unit glazing quantity, pressure all by printing machine control center control. The printing press polishing devices like the glazing liquid supply agencies can control the whole process of polish liquid supply, glazing liquid by electronic double diaphragm pump from liquid storing barrels smoke to polish a liquid hose plate. Liquid surface height and glazing the cycle of liquid by potentiometer monitoring, ensure uniform supply, ultrasonic liquid glazing can monitor the glazing liquid monitors the amount glazing. The 105 global group will offset the roller of glazing plant, have the stuffs the operation as roller of two systems there are also can be used as a reverse operation of the three roller type system. With two roller of chronological operated work, measuring roll was to take off, through open a roller with polish liquid pressure between liquid roller to adjust the glazing of simple structure, coating. With three roller type reverse operation form work, glazing roller and a liquid, and it can get roller reverse operation is very good brightness glazing membrane layer: at the same time in the use of high viscosity fluid, don't have to rely on polish too improve the pressure between rollers to achieve and thin coating of well purpose. This roller of glazing device is short, the relay route contact point less liquid, polish, polish dry not easily transfer liquid even, simple operation is convenient wait for a characteristic.
Scraper type glazing: using close ink scraping knife glazing system, by ceramic anilox roll and enclosed scraping the ink and flexible resin coating knife version roller composition. Its main advantage is through the choice of different ceramic anilox roll, accurately, according to the need of the coating finish coating, save glazing oil; With quickly replace anilox roll, glazing coating edition device and the whole surface coating, local glazing function. Usually consists of two scraper and the measurement of the role of ceramic anilox roll, and under scraper and roller to form closed box structure, glazing by pipeline pump into the liquid. Scraper type glazing device is glazing uniform constant, high quality, and the effect is good, environmental protection, economy, easy to realize good high-speed polishing etc. Characteristics. And can adapt to the gold and silver box surface polish, glazing coating can achieve very high wear resistance.
Hot stamping.
In the fierce competition in the market, in order to increase the added value of products, the more effective anti-counterfeiting packaging, more and more of the packing boxes using hot stamping process. Hot with ordinary hot stamping, LengTang, India, and bump hot stamping and holographic hot stamping and etc way. Commonly used ordinary hot stamping process are plain planish hot stamping and round flatten printing. Because round flatten hot stamping for line contact with hot stamping, base material widely, suitable for large area printing, hot stamping high precision is widely.
LengTang seal: don't need to use heat, but use of metal plate printing adhesive method transfer foil. LengTang printing process cost low, save energy and high production efficiency, is a promising new technology.
The bump hot stamping (also called 3 d printing) : by using modern sculpture technology making up and down the Yin and YangMo with mold, hot stamping and pressure bump process once completed, improve the production efficiency. The sculpture made the transition to mould can surface corrosion of general legal mould elusive stereo anaglyph effect. The bump hot stamping has made hot stamping and pressure bump process finish at the same time, reduce the working procedure and for misregister and of generation of waste.
Holographic logo: using computer technology to change the grating amplitude and frequency, make its effect than the calculated design colour more bright-coloured, more clearly. If this holographic logo as the original copy will produce the large amount of holographic lost, so as to achieve the purpose of security. According to the hologram printing marks characteristics, can be divided into continuous holographic logo printing and independent holographic logo printing. Continuous holographic logo printing is ordinary laser holographic stamping of old products. Independent holographic logo printing is will the holographic logo on the electrochemical aluminum made the trademark design, individual and each pattern in the registration mark are.
Holographic logo can not only has the very good anti-fake properties, can also according to customer need special number or text will be holographic logo. Holographic logo printing to packing boxes, not only will holographic logo printing to their surfaces, and with high accuracy in luxury box longitudinal, packing used more widely.(Gold Printing Group)
