Printing ink

Date:2016/5/9 10:23:46 Hits:5688
 

    Printing definition: through a variety of pressure to transfer the ink to printing substrates surface formed by the replication process of industrialization, the traditional printing plate as a graphic in the middle of the carrier, make the graphic area and blank area isolation by various means, then ink transferred to the product surface, digital printing plate aside, directly to the computer graphic transferred to the product surface, the evolution of technology towards the direction of the fastest, but it seems that there was no evidence of discarded ink printing.

The composition of ink

      Content is the most fundamental purpose of printing, but you have to deliver content, color plays a very important role, nature can show a lot of things, color ink experts first think of the shelf life long and colorful pigment and dye.

      Pigment dye, can't print directly to the product surface, pigment and dye can firmly adhere to the product surface should be attributed to the resin.Most of the resin is solid, the resin for the most part is not a simple resin ink, but formed in the dissolves in the solvent mixture.

      Ink is composed of pigment, resin, solvents, all the printing ink is short of little not the above three kinds of ingredients.

Pad printing ink and printing ink

     Different printing process is not identical to the requirement of printing ink, on ink must also add the appropriate supplement ingredients to make them easier to use in specific situations, such as offset printing ink viscosity, good resistance to water, gravure printing ink is more thin, good liquidity;Silk screen printing ink, will has good permeability.

     Different printing process using ink in total the main difference between ink contains additives is different, this article will mainly talk about silk screen printing ink and printing ink.

      In substrates eligibility, silk screen printing has a great advantage, especially in the shape of plastic hardware electronics and consumer goods industry directly, silk screen printing won a widely admired.However, there is no universal way of printing, silk screen printing is no exception.In a small area and irregular industrial printing area on the surface of the substrates, silk screen printing has met the real trouble, this problem has given rise to the birth of pad printing technology.It can be said that although the pad printing and screen printing technology has very big difference, but they involve extremely similar industrial field.

     The earliest pad printing ink is silk screen printing ink instead of, practice proves that there is nothing absolutely not adapt.Ink used in different printing environment, however, differ in eligibility for certain, such as pad printing inks, users do not require it to have screen printing ink through sex, but will ask its better thixotropism and table stem phenomenon, to ensure its from steel to plastic head, substrates transfer process more accurate.Use a dedicated pad printing ink will undoubtedly easier to improve printing quality.

      MARABU first developed a dedicated pad printing ink.Through the function of additives to keep the surface tension of the ink at a constant range, in order to make the ink transfer printing process to maintain absolute consensus.Ink transfer process and the properties of the rubber pad printing head also is closely linked, and the surface tension of the rubber pad printing head control within the scope of the similar and pad printing ink, it seems, is a systems engineering, essential purpose is to improve the printing ink transfer efficiency.The Japanese is to solve the problem from another Angle, they on the pad printing machine equipped with rubber head cleaning device, however, equipped with rubber head cleaning device mainly lies in the control of the ink transfer, and transfer efficiency did not increase.

       MARABU have 6 (which is actually eight) pad printing ink to choose from: GL, mainly used in metal, ceramics, glass surface, the basic is a two-component ink, you need to add GLH hardener, TPR, is in the SR series screen printing ink on the basis of the improvement of pad printing inks, whatever the SR material that can be used in pad printing process can make the TPR;By the same token, TPY is silk screen printing ink in PY series based on the improved pad printing inks, can be chosen for the material is very difficult to printing surface TPU ink;TPT is mainly used in the oil cup pad printing ink pad printing machine: the stability of the TPL is better, in the long time maintain good uniformity of the friction condition.And there's two kinds of TPP and TPS.

     Worth, screen printing ink and pad printing ink is completely generic, just need to add additives to change the printing eligibility.So there is no special pad printing ink, screen printing ink can be used instead.

Ink color: color, the color, the standard color

      Natural color is rich and colorful, if you want to show all the ink is impossible, there is two ways of copying color in printing, one is direct deployment of color printing, the other is a through the superposition of four color printing.

      Four color is according to four types of pigment in the CMYK color model superposition principle to copy the color, generally four color replication technology to replicate our basic requirements of color, it usually takes four color has a level of manuscript replication technology.

       Four-color ink replication advantage lies in the level of original, for the majority of advertising design and creativity as well as industrial printing, use the color is a very common phenomenon.The color is more able to reflect the designer's ideas, were also more likely to prevent infringement.In theory, can also use the primary color mixing, color hue but do it not only difficult to exactly match, the possibility of waste of ink is also increased.So the printing color copy replication technology includes two aspects, one is inclined to copying with four color ink color, is mainly used in the original level, existence of superposition between color and color.Color printing because of the complicated chromatology involved and the principle of network synthesis, so it is printing technology is one of the most difficult to master the technology.How to control from the manuscript to the film, plate and site changes of substrates is the key link in color printing technology.

        The color to use colors don't stack with each other, because nature is unusually rich pigment, make the kinds of color ink is very much.- a sense of color all color refers to the primary, the implication color is unlimited.The PANTONE company establish standard color ink color, and based on the production of color printing ink appear today widely used color swatches.PANTONE color card is actually a very small part of the color, we call it the standard color.Now Europe also made the European standard color, we can see the two standard color as a subset of the set of all the color.Of course, all kinds of color printing standard color allocate each other can also modulate the color very much, color is one of the world is engaged in the printing business of the company's common language.

      What on earth is red red, who also said not clearly, but if tell you the PANTONE color card number, you will easily find the ink.Ink ink manufacturers can provide according to the standard color card production relations to the vital interests of the users, choice of the ink color is an important content, although the four color printing technology is very difficult to master, but when selecting primary color ink seems to be very simple, because the ink four-color ink only a set of manufacturers., by contrast, the choice of the color ink is more trouble, if a designer is just use some standard colors to express his design ideas, you just bought this kind of ink, you can choose this kind of ink, but fewer and fewer designers should do so, may be the boss also don't allow him to do so, because the more easy to get, imitation is also simple.The subtractive method of deployment of ink is also based on color science, but to modulate the accurate color soon, is just as important as theory and experience.

Select material and ink

      Offset printing method may not be so troublesome, for paper printing eligibility is very good, basic need not consider adhesion problem, but the silk screen printing and pad printing is not so simple, screen printing and pad printing substrate, can not use a printing ink, ink manufacturer is a must to fully adapt to the market to produce all kinds of printing ink.We can be simply divided into the following several kinds of substrates to: 1.In plastic in the family, PP and PE, PP, PE is a very big dosage of two materials, the first is that they have good physical properties, chemical corrosion resistance is very good, most solvents are not them, so in the coatings, cosmetics, plastic film and electronic products are widely used.But it is also they hard to printing the reason, because their molecules are polar molecules.At present, the printing of the two materials widely used prepress processing method, the common way is to flame treatment and high frequency.MARABU company production of Pl treatment water is actually a kind of strong oxidizer, rough surface are formed by oxidation material surface to achieve good adhesion of ink.Development from processing PP ink is also the goal of many manufacturers, technology is also the basic mature, but also can't avoid dealing with ink in the PE surface good adhesion.PP series ink MARBU is free treatment of ink.

      1. In combination with prepress processing, can be used on the surface of the PP, PE, ink varieties more.We discuss here is solvent ink, for UV ink, prepress processing is required, there is no free treatment of UV ink.It should be said that in the current printing technology, printing on PP, PE material, it is difficult to achieve stable quality control.

      2.ABS, PC, PVC, PS, AS some polar material is easy to printing, such AS the materials mostly without prepress processing can be printed, this part of the ink is all manufacturer's strengths.

      3.Glass, metal, ceramic substrates, such as surface there are no absorption properties, according to conventional methods manufacturing printing ink work hard, for the most part use two-component ink.

       There are more and more engaged in pad printing screen printing enterprise, can find products suitable for customers of ink means the ability to get the order.But suppliers according to suitable for this kind of material, to determine whether really can meet the requirements, the key is in accordance with the requirements for testing, if the test effect is not good, might as well change the ink.Sometimes may get the wrong information and technology, must understand the test method, so a lot of ink can't printing method is achieved, and the wrong is an important reason for the results of the test method.If not solve some problem, want to contact timely and ink manufacturers.Preceding narrative provides the important information is, first of all to understand customer's product is what material, secondly to be familiar with the choice of ink information, and then detailed test, until customer satisfaction.Theoretically can not printing products, in fact, many products printing make you worry, the key is to have enough test methods to solve.
