Description
Technical field
The invention belongs to CTP offset plate field, be specifically related to a kind of environmental protection ink-jet CTP version.
Background technology
CTP (CTP) technology is the state-of-the-art plate-making technology of offset printing plate-making in the present age, and its plate used is called CTP version.Along with the development of the key technology such as information, manufacture, before print, plate-making is positive with all strength towards CTP (ComputerToPlate, CTP) widespread development.CTP refers to after original copy information being input to and processing in computer, by computer control, directly information is exported the technology of forme, its essence is and control laser beam with computer instruction, the information on the digitalized electron space of a whole page to be printed sequenced by computer is delivered on printing plate, directly obtains the technology for printing forme.Offset printing CTP plate mainly has photosensitive plate, Thermal sensitive plate and ink-jet plate according to imaging mechanism, and wherein Thermal sensitive plate is in the market in the highest flight.
Recent years, ink-jet printer achieves very big development, and inkjet printing speed is fast, resolution is high, and the price of ink-jet apparatus and ink is relatively low, thus it is less costly to make a plate, simple to operate etc..This makes ink-jet CTP develop quickly, can be widely used in books and newpapers and periodicals printing.Ink-jet CTP printmaking is usually PS version type ink-jet CTP version.PS version type ink-jet CTP version is to repaste the ink-jet receiving layer of layer of transparent on common positive PS printing plate, then on ink-jet receiving layer, picture and text are printed with ink-jet printer, on-hook printing is got final product after processing then through printing down, development, washing, it eliminates the technique such as film, manual imposition and corresponding equipment compared with traditional PS version mask-making technology, shorten the plate-making time simultaneously, advantageously reduce cost.The patent of major part ink-jet CTP version is this PS version type ink-jet CTP offset master both at home and abroad, but this PS version type ink-jet CTP version still uses PS version, namely on aluminum substrate, to be coated with solvent type photoresists, lithography process is identical with traditional PS version simultaneously, also want the operations such as printing down, development, washing, as controlled the improper plate-making quality that also can affect, contaminated environment is also wanted in developer solution discharge simultaneously, is unfavorable for environmental protection.
Prior art was also disclosed a kind of paint ink and the environment-friendly type on-press-coating ink-jet CTP offset master being made thereof.Using the naked version ink-jet CTP version of environment-friendly type that the paint ink of the present invention is fabricated to, its processing technology is simple, eliminates the techniques such as printing down, development, washing, is absent from environment polluting, also reduces printing cost simultaneously.But this technology yet suffers from press resistance rate not high enough (2-3 ten thousand), the shortcomings such as light fastness is good not, and resolution is high not.
Summary of the invention
The purpose of the present invention can be achieved through the following technical solutions:
It is an object of the invention to provide a kind of novel environmental protection ink-jet CTP version, it is from processing technology, and raw material comprehensively optimizes, and simple for production, and the CTP version press resistance rate prepared prints more than 100,000, and light fastness is splendid, and resolution can reach significantly high.
A kind of novel environmental protection ink-jet CTP version, it is prepared from by the following method:

(2) special paint ink is prepared:
nullAccording to weight portion，By 6 part of 50% acrylic acid-acrylic butyl acrylate copolymer emulsion (M=25000 ± 200)，Mol ratio acrylic acid: butyl acrylate=1:1.5，It is sequentially added into 2 parts of pigment wherein，0.2-0.3 part trehalose，0.05 part of malic acid，0.02 part of tea saponin，0.08 part of polyethylene glycol oxide alkyl phenol，5-6 part Polyethylene Glycol，0.5-0.8 part glycerol，0.5 part of isopropanol，0.8 part of hexamethylol melamine resin，0.1 part of molecular weight is the phenolic resin of 9000，0.15 part of molecular weight is the phenolic resin of 120000，16 parts of deionized waters，30min is stirred with the blender that rotating speed is 300 revs/min at 30 DEG C，It is cooled to 5 DEG C，Again by the mulser high-speed stirred 35 minutes of 1500 revs/min，50min is pulverized again with sand mill，Regulate pH value to 8，Insoluble impurity is fallen or pigment that particle diameter exceeds standard with the filtering with microporous membrane of 1 μm，Namely paint ink is obtained；
(3) adopt above-mentioned paint ink, directly pattern is printed upon aluminum substrate with ink-jet printer, after conventional solid version processes, namely obtain the environmental protection ink-jet CTP version of the present invention.
The invention have benefit that:
(1) present invention is from base version, and to the processing technology of paint ink, raw material comprehensively optimizes, and simple for production, and the CTP version press resistance rate prepared prints more than 100,000, and light fastness is splendid, and resolution can reach significantly high.
(2) paint ink that the present invention prepares does not block printing head, stable performance, can quickly be attached on edition base after being printed upon on aluminum substrate, will not trickle and cause picture and text to obscure, and water-fast, thermal sensitivity is high, Gu version temperature is low, the time is short.
