On-demand printing supplier capacity has increased significantly in recent
years, in addition to have more advanced printing equipment, they can provide
customers with services have become more abundant. In addition to the ordinary
black and white and color templates, they can also at a lower cost to produce
different number of color hardcover book.
Through the use of electronic data
interchange (EDI) orders and billing systems, on-demand printing enterprises can
simplify the process of customers and cooperation, and can according to
customer's requirement would be personalized products to clients.
The current
economic environment and technology changes prompted the publishing industry to
speed up the acceptance rate of on-demand printing patterns. With fewer long
printing order, press should aware to invest in new media and digital
transmission technology.
Most on-demand printing service providers are
according to the different business model to provide service for the customer.
In general there are three main kinds, respectively is: according to the order
of printing, the short version of the drop shipping and the short version
printing. Compared with the traditional offset printing, the business model
surface look more expensive, but as long as the understanding that you will be
able to find it with the benefits. The most important thing is to see how you
measure the real cost and value of each service.
No matter what kind of
business model, the customer must provide meet certain standards of digital
files for printing. According to the different business model, these live a boot
cost will by providing on-demand printing printing enterprise all or part of the
service.
According to the order of printing is by far the most powerful at
the same time also is one of the most flexible business model, but not all of
the print service providers can provide the service. Using the business model of
printing service providers to offer clients an arbitrary number of printing
services, ranging from one to several hundred, but also is responsible for
printing the finished product to the terminal consumers. Customers can order
automatically by the electronic data interchange system and ordered products
printing enterprise to ensure that consumers will not out of stock.
In a
short version of the drop shipping business mode, the printing service providers
tend to live a short version of the 1500, and will ship it to the distributor or
wholesaler.
In a short version of the printing business mode, printing
service supply chamber of commerce in 1000 ~ 1500 short version live, and to the
customer's warehouse.
Business model characteristics
According to the
order of printing service categories of business models, the most widely and
most popular with publishing enterprises. The current state of the economy and
the people of electronic media, make the business model has become more
attractive. Because the customer does not need to develop a plan of printing,
don't have to worry about the backlog of inventory, even will not be lost
because of shortage of the order. Considering the inventory, packaging,
shipping, rework, and other costs, according to the order of printing cost is
not higher than the traditional offset printing. In addition, the current
printing enterprise in rotary offset press printed on the long version live
profit space, generally between 1% ~ 2%, and the short version of the profit
space of digital printing can reach 30% ~ 40%.
For those who have not set up
branches in all parts of the world's international publishers, the short version
of drop shipping is a very good choice. Press the world bank, for example, they
mainly through distributors and other agents to his published works are sold to
all over the world. If you're in the Sahara desert in Africa published a book,
the reader can be in the nearest place for on-demand printing, it can save a lot
of cost. At present, in Asia, Africa and other countries new print-on-demand
enterprises are promoting this kind of business model. Like to order printing
mode, this kind of business model for printing enterprise profit margins are far
higher than that of rotary offset printing long version, and more likely to be
accepted by the press.
Short version printing business model with a short
version of the drop shipping are very similar, the only difference is that its
finished goods to be sent to the printing press in the warehouse, and the
publishing house is responsible for the distribution. This kind of business
model has the advantage of high efficiency, as long as the production process
smoothly and digital documents conform to the requirements, can replenish
inventories at faster than traditional printing speed.
The current
development direction
The current print-on-demand three kinds of different
business models. Some publishers have adopted pure on-demand printing mode and
warehousing, stripped of their traditional business. Some publishers are
considering to reduce the size of the product classification, in order to reduce
the cost and risk, improve the print listed speed. Also some press considering
to introduce their own digital printing equipment, because after all, digital
printing can reach 30% ~ 40% profit space, and use your own equipment to print
more cost can be saved in the future.
Especially according to the order of
printing mode, can minimize the investment risk, eliminate complex amount
estimation and printing planning work, and the customer only need to pay out of
that part of the actual sales of the product inventory costs. This can greatly
reduce the risk of loss due to shortage of orders.
Provide consumers with the
content they need is the one of the main trend of the publishing industry. All
publishing companies should make an effort to understand the needs of customers,
and through some may cause printing demand but will not affect the content value
of new media transfer their products to the customer. As a result, they have to
find ways to reduce the cost of traditional publishing model, and the limited
funds to the more valuable content in the process of development. (Gold Printing Group)

How to better the print work done
The preparing work before, plate burning
In front of the plate burning, PS version must be thorough, carefully check, make sure that the PS version of the surface is smooth, level off, there is no dirt, scratches, etc. In addition, the PS version of the storage environment temperature and humidity should be appropriate, avoid direct exposure to the air, and the storage time not too long. In addition, must be kept clean neat, pervious to light glass plate burning machine (usually use alcohol to wipe), printing film, no dirty.
(1) adjusting exposure
First of all, took a piece from the PS version of side length is 100 mm small pieces as test material, and then blank LiuSuanZhi spread on it, after the exposure test, will take off, LiuSuanZhi observation PS any traces on the surface, and then adjust the exposure time exposure again, until it is concluded that the standard of exposure time.
(2) ensure the enhancement effect
Solution concentration, developing temperature and developing time are the main factors influencing the imaging effect. The higher solution concentration, developing the higher the temperature, the longer the developing time, the surface of the PS version of photosensitive resin and the reaction of developer more fully, the degree of exposure of dissolved the more thoroughly, but also can create outlets contraction, or even loss of small branches.
(3) repair the PS version
After finish development work, carefully check the PS version of the graphic and blank section, the existence of dirty point areas to repair in time. In the process of plate burning, film edge will leave a mark in the surface of PS version, so also want to repair these tracks. PS version after the repair, need retouching cream quick rinse with water, rinse when adopting the way from inside to outside, to exempt the version of the paste was rushed to the graphic part.
(4) to protect good plate
In order to protect the sun good plate, coated with a layer of the plate surface hydrophilic rubber protection, to prevent the oxidation of the blank part is. As far as possible when glue make gum liquid coating, bao hou uniform scratch plate layout and avoid hard objects. At the same time, pay attention to bask in good plate in the clean and avoid light place.
(5) check the quality of the plate
First, check the actual situation of a node with a magnifying glass. If site last as, full, 2% of small branches, 3% of the points clear, intermediate node increases obviously, dark color does not appear paste version phenomenon, concluded plate standard quality. Then, check the graphic location on the surface of the plate, diao mouth and pulling the pin position is accurate, the plate layout whether there is a crease, graphic is complete. The existence of abnormal areas to handle in time. (Gold Printing Group)

Introduction to common problems in the gift box gluing process
In the process of packaging products, such as glue gift boxes, always easy to appear the following questions:
After brushing glue quantity is too thick to pressing glue overflow, both affected the product is beautiful, but also prone to mutual adhesion between boxes. If this situation happened after the brush glue should be air buy 2 ~ 5 minutes, wait for after adhesive is a bit dry pressing again. Brush glue too thin, and the drying time is too long, and can lead to poor adhesion fastness, and sometimes there will be can't glue at all.
Have no pressing or pressure is too small, will cause adhesive products after bounce off automatically, this kind of situation mainly for large stiffness of the product, so pressing at least half an hour, because there are a lot of adhesive is a type of adhesive contact, so you have to make the two glued surface, effective pressure in unit time, if the viscous force is less than at the beginning of elastic products, products will bounce off, so the general products are required to have a 0.5 hour press time.
Some manufacturers in order to saving the cost of raw materials with complex film adhesive and box or blended with white glue to use relatively large amounts of water to dilute the adhesive, thus resulting in the insufficient adhesive fastness, as well as on the membrane, the phenomenon of the poor adhesion. This kind of situation is very dangerous, is also in violation of the principles and process of binding.
Packing box degumming phenomenon in the winter. This is mainly because some adhesive of low temperature resistant performance is not good. Below 5 ℃, the surface of the adhesive will lose activity, and led to the decrease of the sticky relay or disappear. But on a hot summer day, stick good packaging will be out in the warehouse or transportation trunk, degumming there sprang open. This is mainly because of this kind of adhesive high temperature resistant performance is not good, at 50 ℃ ~ 60 ℃ temperatures of the sub tender, strength decreases, resulting in packing box come unglued.
Packing box at the beginning of the taped (generally) for half a month time bonding effect is very good, but with the extension of time, the phenomenon of degumming box will appear. This is mainly because adhesive bonding of persistent performance is poor, because most add some plasticizers in adhesive, with the extension of time, resulting in rubber plasticizer to paper-based migration harden, crisp so that products come unglued. On the other hand because the adhesive contains plenty of unsaturated bond, cause product aging resistance is not good storage period extend film brittle, make the product come unglued.
If the warehouse is very wet, so long time storage in it, not only the product of the humidity will exceed bid, and the product also can appear come unglued. This is mainly because the product to absorb moisture, and the water resistant performance of the adhesive itself has bad, leading to a rubber soft produces delaminating. (Gold Printing Group)

Brazilian publishing experience the biggest decline in 10 years
According to the Brazilian economy research foundation (FIPE) released the
latest statistics show that Brazilian publisher in revenue of $2.439 billion
last year, more than $2011 in 2.147 billion grew by 3.04%, considering the
inflation factor (5.84%), Brazil's book market shrank 2.64% in real terms. This
is also the industry experienced the biggest drop since 2002.
The Brazilian government procurement budget is to reduce the book market in Brazil in 2012, a major reason for poor performance. The Brazilian government last year purchased $644000 worth of books, was down more than 10.4% in 2011.
Sales market is actually growing, but not enough to offset the decline in government procurement budget. In 2012, Brazilian publisher sales were $1.795 billion, more than $2011 in 1.688 billion grew by 0.49%, but that didn't make any sense. The book market sales in Brazil since 2008 there has been no real growth. Government procurement in the publisher and the proportion of income is 26.4%, more than 28.7% in 2011 fell slightly. On the number of it, Brazil has sold 268.6 million copies in 2012, more than 284 million copies in 2011 dropped by 5.43%. Among them, the publishers to sell 166.4 million copies of the government's books, was down more than 10% in 2011.
Publishers to worry about the other problem is publishing the continued volatility of prices, because it is influenced by tax policies and government procurement budget is the largest. Grew by 12.46% in 2012, the average price of publishers, this means that the average price of books during the period of 2011 ~ 2012 grew by 6.25% in real terms.
The average price of mentioned here refers to the amount of gross income divided by total sales in the industry and the data, and can't really reflect the price movements of book. In fact, Brazil's economy research foundation estimates that Brazil's book prices have fallen by 41% since 2004. (Gold Printing Group)

A brief overview of common printing security hidden danger
We summarized the common printing a safety hazard:
1, the safe hidden trouble that bad operating habits
For all the security hidden danger, harm is the most powerful, the concealment of the at the same time it also is the highest, overcome index is the most difficult. More than 90% of the operator is due to the operation is not carried out in accordance with the requirements in the process of operation that caused the accident. Here we will list some common bad habits, so that a wake-up call for everyone.
A. plate (rubber cloth) used to operate: general rotary press plate is more, the operator is used to hang version of two or more groups at the same time, in order to save time, improve work efficiency. Sheet-fed offset press plate also have this kind of phenomenon. Interim plate, in order to speed up the progress, and the teacher is to help, that is one version, one point switch. Safe hidden trouble, plate (rubber cloth), if two or more people operate at the same time, a bit not concentrating, hand skid or unexpected machine problems, it is easy to finger involved, cause personal injury.
Preventive measures:
(1) version of work by one operator, with the hand gently knead plate towing pin and gasket, make sure that pages are not scratch and liner level off, (2) the plate one thousand mistakes or meet "electricity", hand to loosening, don't hold the plate, will not have much loss, if hold, will cause other accidents.
(3) the situation is different for all kinds of machines. If you really need to use hand push plate, can put some talcum powder on the layout, the prevention of accidents.
2. Spade ink used to operate, due to the need of distributing, the operator used with ink shovel movement back and forth on the ink roller, distributing, add ink or shoveled away excess ink ink roller. Safe hidden trouble, when in high speed operation, this belongs to the frequent accidents of dangerous operation, once the ink blade Angle pin offset or operation of the ink shovel met series of ink roller surface uneven, ink shovel will be involved in the main series of ink roll and rubber roll and accident, between light scratch plate or rubber roller, or rolling bad blanket or drum, even in the drawing ink shovel the accidents caused by the controls in a flash.
Preventive measures:
(1) the first thing to heel, focused, hold the ink scraper, don't look in all directions.
(2) find print ink quantity is not enough and must be manually add ink, ink scraper must hold in the hand, and to raise the little ink roller, after waiting for the roller stopped again.
(3) to shovel the ink, the ink shovel to, which is based on the main series of ink roller, conveniently depend on the rubber roller, an impending, ink scraper with bunch of ink roller contact Angle is not less than 45 °.
3. In addition to the dirty habits operation: rotary press and sheet-fed offset printing presses, often appear leather or rubber roller ink, paper, cast in plate picture and text part of the phenomenon. Affect the quality of the product. At this point, the operator is often used in the machine is running to remove dirty fingers.
A safety hazard: this belongs to the illegal operation of dangerous operations, resulting in the printing of the accident. Under the condition of the high speed machine operators to get dirty point location and erasure, available time is quite short, and the strength not wipe off, only to start early, take strong to stick it on the plate dirty point on the graphic (or ink roller) removed. A slight mistake, finger are likely to enter the plate cylinder space. If it is hung up without relying on the operation, is likely to be brought into the cylinder with one hand, the accident caused by the rolling hand.
Preventive measures:
(1) a week regular inspection of the machine all the safety insurance device and main motor brake mechanism. Make sure the machine sensitive, reliable, and found that the problem timely repair.
(2) the operation is to focus, not suspended operations, wipe dirty, palms must rely on between the plate cylinder and rubber drum of the shaft, or on the water roller protection safety hood, pay special attention to the palm relying on the force should be greater than the force of finger wipe dirty point.
(3) if the dirty point much effect on printing, should stop check and timely replacement of rubber roller or paper, ink, fundamentally solve the problem. In the daily production, must establish the idea of safety first, cultivate good habits of operation, or in the event of accident, the product quality and economic benefit etc. Everything will be impossible. So, bad operation habits is the biggest killer of safe hidden trouble. (Gold Printing Group)

The influence of offset printing ink balance and quality
Lithography is the use of the principle of oil and water don't mix, plate
graphic department can oil-wet hydrophobic, gap department water before with
hydrophilic oleophobic selective adsorption. Another characteristic is using
indirect printing, offset printing using dot color way for color copy. Offset printing ink sure if appropriate, in
the normal transfer of imprinting, inky depth, color correct, print dry and
sticky dirty, etc is very important. Can accurately grasp and control the ink
balance, therefore, is to ensure that the print quality not disorderly of hub.
As a high-tech printing workers, should not only know the ink balance
relationship, more master ink balance technology and essentials should be
polished.
Ink balance refers to the certain and the printing pressure, printing speed adjust the supply of education version liquid, emulsion to make the ink contains education version after the volume of the proportional control in 15% ~ 26%, and form a level slightly water-in-oil (W/O) emulsion inks, with minimal amount of feed liquid on the plate printing ink.
Ink balance is the most important thing in education version control fluid and ink. Education version fluid is composed of water and surfactant, education version fluid can be fully wetting layout, cleaning ability and not disorderly of pH value, ensure layout doesn't dirty.
1) the role of education version fluid
(1) in the department of plate gap formation water film on average, in order to prevent the ink on the graphic to open branch of infiltration, to prevent dirty version.
(2) using the education version in the liquid electrolyte with bare metal versions due to abrasion produces chemical reaction, constantly create new layer, maintain layout department of hydrophilic gaps.
(3) control the temperature of the layout of printing ink. Because the new printing presses faster and faster, with print speed too fast will make the ink in the high-speed transmission temperature, the activity of the ink is increased, which resulted in increased network. So puts forward new requirements for education version fluid high-speed machine, namely the education version fluid in contact with the ink forme roller through the layout, can reduce the temperature of the ink roller and ink.
(4) do not make by larger or smaller. Education version with not disorderly plate is required by department and the function of the relative position vacancy department, guarantee in the whole process of printing, graphic neither to expand or narrow.
Ink generally composed of pigment, filler, links and auxiliary additives, selection of ink should be fully considered when ink rheology function and optical function.
Ink rheology function to determine whether the ink has good printing function of main basis. Ink rheology function mainly depends on ink link, of course, also can be regulated by the appropriate auxiliary additives. Ink rheology function evaluation can be reflected through the main function of ink rheology indexes, namely, ink viscosity, viscosity, thixotropy, yield, viscoelastic and activity and so on. In practical production, only grasp the function index, to be familiar with various types of ink printing property, so as to achieve the purpose of the selection to meet the requirements of printing ink.
Print must exist at the same time, surface printing ink and water balance, the purpose is to keep both graphic printing area maximum ink quantity, make bright inky, saturated, points clear bright and clean, but also to keep the printing area clean and tidy, which requires attention to adjust the volume of water and ink in the produce of the relationship.
In printing, the printing quality of imprinting inky depth, in addition to related to the amount of the ink ink fountain, also directly affected by the water supply and layout of ink balance. When the layout of water increases, the imprinting inky dodge becomes shallow gradually. Conversely, reducing water supply section water, imprinted ink is relatively deep than the original. So, more or less ink quantity and layout of water supply will change imprinting inky depth. In the printing process, should be adjusted according to actual situation. Should not rely on to reduce the water supply to progress as required, because the water is too small, loss of balance of ink, easy to make dirty with the vacancy department.
But the need to prevent water on the big ink. When the moisture of excessive, inky becomes shallow, must have to actual situation, mistakenly assume that ink quantity is little, not to reduce the water supply, but to frequent increase in the volume of ink. Ruth reciprocating to increase water supply for ink, resulting in a vicious cycle, the ultimate water ink big all ills, printing from otherwise normal operations.
Experienced printing workers, in actual production, often under the condition of can't afford to ensure plate dirty, control the water supply in the range of as small as possible, and the amount of water and ink is not disorderly state, so it can ensure the printing quality before and after the inky depth is consistent and printing work.

Ink balance refers to the certain and the printing pressure, printing speed adjust the supply of education version liquid, emulsion to make the ink contains education version after the volume of the proportional control in 15% ~ 26%, and form a level slightly water-in-oil (W/O) emulsion inks, with minimal amount of feed liquid on the plate printing ink.
Ink balance is the most important thing in education version control fluid and ink. Education version fluid is composed of water and surfactant, education version fluid can be fully wetting layout, cleaning ability and not disorderly of pH value, ensure layout doesn't dirty.
1) the role of education version fluid
(1) in the department of plate gap formation water film on average, in order to prevent the ink on the graphic to open branch of infiltration, to prevent dirty version.
(2) using the education version in the liquid electrolyte with bare metal versions due to abrasion produces chemical reaction, constantly create new layer, maintain layout department of hydrophilic gaps.
(3) control the temperature of the layout of printing ink. Because the new printing presses faster and faster, with print speed too fast will make the ink in the high-speed transmission temperature, the activity of the ink is increased, which resulted in increased network. So puts forward new requirements for education version fluid high-speed machine, namely the education version fluid in contact with the ink forme roller through the layout, can reduce the temperature of the ink roller and ink.
(4) do not make by larger or smaller. Education version with not disorderly plate is required by department and the function of the relative position vacancy department, guarantee in the whole process of printing, graphic neither to expand or narrow.
Ink generally composed of pigment, filler, links and auxiliary additives, selection of ink should be fully considered when ink rheology function and optical function.
Ink rheology function to determine whether the ink has good printing function of main basis. Ink rheology function mainly depends on ink link, of course, also can be regulated by the appropriate auxiliary additives. Ink rheology function evaluation can be reflected through the main function of ink rheology indexes, namely, ink viscosity, viscosity, thixotropy, yield, viscoelastic and activity and so on. In practical production, only grasp the function index, to be familiar with various types of ink printing property, so as to achieve the purpose of the selection to meet the requirements of printing ink.
Print must exist at the same time, surface printing ink and water balance, the purpose is to keep both graphic printing area maximum ink quantity, make bright inky, saturated, points clear bright and clean, but also to keep the printing area clean and tidy, which requires attention to adjust the volume of water and ink in the produce of the relationship.
In printing, the printing quality of imprinting inky depth, in addition to related to the amount of the ink ink fountain, also directly affected by the water supply and layout of ink balance. When the layout of water increases, the imprinting inky dodge becomes shallow gradually. Conversely, reducing water supply section water, imprinted ink is relatively deep than the original. So, more or less ink quantity and layout of water supply will change imprinting inky depth. In the printing process, should be adjusted according to actual situation. Should not rely on to reduce the water supply to progress as required, because the water is too small, loss of balance of ink, easy to make dirty with the vacancy department.
But the need to prevent water on the big ink. When the moisture of excessive, inky becomes shallow, must have to actual situation, mistakenly assume that ink quantity is little, not to reduce the water supply, but to frequent increase in the volume of ink. Ruth reciprocating to increase water supply for ink, resulting in a vicious cycle, the ultimate water ink big all ills, printing from otherwise normal operations.

Advocate the practice of using water is small, the ink thickness, the water of the little finger is conditional on the level of vacancy layout department doesn't dirty minimum water; The so-called ink thickness, is built on the basis of water small, water ink caused by excessive emulsification, thick ink layer is impossible.

Germany slowly increasing digital printing market, challenge and pressure
Recently, "the German printer" issued digital print advertising and directory
market statistics report, according to the report, the German market for digital
print advertising and directory output rose to 20 million euros from 140 million
euros, obvious growth means that Germany digital printing market has huge
potential.
It is reported that the current printing market is growing, not only in China, India or Brazil, and also in Germany. If observed the entire printing market, people will find some areas or falling. Gravure and offset printing, for instance, advertising and catalogue printing market (total 1 billion euros) from 2009 to 2011 reduced to 110 million euros. But at the same time digital printing advertising and directory market growth by 20 million euros to 140 million euros, grew at an annual rate of 190% a year. So, although another aspect of the market (gravure and offset printing) loss of 110 million euros, but digital print advertising and directory market surge - although similar printing products are advertising and directory. In addition, from 2009 to 2009, the production of gravure magazine total loss of 220 million euros. The demand has disappeared.
The opposite development momentum, printing market potential growth and a variety of opportunities. In order to realize these opportunities, the enterprise not only to see change as an opportunity, and want to start the change process of ignition in person. Have the strategic foresight entrepreneurs in economic history always arouse the process of "creative destruction". They create new methods, new products and new markets. In recent years, in the printing industry to this new situation: it is a new method, such as automation, stability of mixed printing production to successful online printing plant; The second is the new product, such as can design independently by end customer online photo book, this is an unprecedented; Third, new markets, such as printing of electronic device, the new application field for display, battery, photovoltaic products or smart textiles.

Some characteristics about product catalog design and printing
The design of the product catalog printing, in the early good to communicate
with the customer, let the customer be clear at a glance, to maximize the
directory in which the benefit.
Catalogue of text and graphics, is a key design element in the design, text and graphics complement each other, synergies.
Catalogue design printing contains connotation is very broad, compared with the general product catalogue, product catalogue design printing not only include the design of the cover, also includes the product catalog of font, size, color, layout, and so on.
Being a whole, the overall design for designers, especially need to have a grip. From the catalogue of the whole book size, font choices to catalogue and the change of the format, from the arrangement of the picture to the color setting, from material selection to the printing process of innovation and do overall consideration and planning, and then reasonable mobilize all design elements, will they organically fuses in together, in the service of connotation.
A good product catalog design and printing of the success or failure is decided the design localization. Namely to previous customer communication, good product catalogue design printing half from the previous communication, in order to reflect the consumption needs of customers, for customers to bring more sales.

Dot enlargement problem how to solve the offset printing process
Printing in the network increase phenomenon is inevitable, but you can control.
Normally, coated fine print dot increases value must be less than 12%, general
printing quality to less than 18%, newspaper printing are controlled within 35%
(50% generally refers to the network). In the process of production, can
effectively control from the following several aspects.
1. Select high-quality materials, reasonable control the exposure time and solution concentration
Drying plate picture and text clear, network system, can guarantee the network transfer effect, and can guarantee the plate have higher resistance force. Usually to ensure that 5% of the dot is not lost, 95% of the dot is not blurred.
2. Strictly control the printing ink in the balance
In the process of printing, if water supply is too large, can lead to a layout for the ink to increase, the ink layer thick, ink emulsification is severe, causing imprinted dim without burnish. Boot in production process, in order to reduce waste, usually in the boot will be increased to 150% of the normal water level, after the normal printing, water should be gradually reduced to normal, guaranteed by clear, saturated luster.
3. All kinds of printing pressure control in a reasonable range
The plate cylinder and rubber roller pressure control between 0.15 ~ 0.20 mm, and make sure that two parallel version of the ink roller and the plate cylinder, under 100 mm in diameter on edition, ink roller and printing plate cylinder pressure width is 3 ~ 4 mm in diameter 100 mm or more depends on the version of the ink roller and printing plate cylinder pressure width is 5 ~ 6 mm.
4. The correct version control run liquid concentration
Education version liquid concentration control the balance of ink and print quality plays vital role. Education version suitable concentration of liquid can quickly rushed to locations around the "dirt". If education version liquid concentration is low, dot around the ink cannot be removed, while the increase lead to network, or lead to paste version; If education version liquid concentration is too high, it will led to the decrease of the PS edition print resistant force and education version of liquid waste. Usually run version solution of pH control in 4.0 ~ 6.0, conductive value control in the 1400 us. (Gold Printing Group)

Paper box puzzle printing process after the two big impact
Carton puzzle is in accordance with the principle of saving paper, as far as
possible on the premise of conjunction, multiple cartons made a most compact and
Mosaic for the dimension of a printing machine printing. But the carton
production process after the more involved, different methods of puzzle for the
quality and efficiency of process after the different effects, the reasonable
way can make the process after complete, if improper puzzle will brings to the
process after the unexpected trouble, cause cannot be completed, and even had to
rework. Therefore require puzzle personnel must be familiar with the process
after printing, there best for
quality control.
1. The influence on die cutting process
Die cutting is pasting box process before the procedure, die-cutting quality has direct influence on the quality of pasting box.
(1) on the die cutting pressure
After die cutting stripping will get one box of billet, to ensure that each box of billet crease and clear, smooth incision, meet the requirements of molding, die-cutting pressure adjustment is the most crucial, which requires the cartons when the puzzle from the nearest distance between two line is not less than 3 mm, namely general carton minimum distance is 3 mm. Otherwise, will be very troublesome when do die cutter, at the same time also can affect the adjustment of the die cutting pressure, that affect the quality of carton die-cutting.
(2) the effect on the die-cutting rules to adjust
Under the premise of meeting the production requirement, the idea of staff generally will try to improve the layout on the number of spelling, such not only can reduce the production cost, also can improve the production efficiency of equipment. But it also brings another inevitable problems, the paper in the process of printing takes expansion problem, especially the pumping bilge filar detailed direction vertical paper would be more serious, with the corresponding die cutting version size won't appear this kind of change, if the spell the number is too big, will cause to transfer part of the box on the dislocation pattern generation, has done a lot of difficulty to the operating personnel adjustment die-cutting rules.
2. The effect on pasting box process
If the carton processing automatic pasting box machines, when the puzzle must pay special attention to cannot blindly in pursuit of saving paper and to do the mouth is too small, or in order to increase the side pressure of the cartons and will make a living doing too large. Because automatic pasting box machines for carton mouth size has certain requirements, and the same device with different type box mouth size requirements are also different, generally is 30 ~ 80 mm.
