Embodiment 1

[0017] A new type of environmentally friendly inkjet CTP plate, which is prepared by the following method:

[0018] (1) Preparation of aluminum plate base:

[0019] Under the condition of 30°C, put the model 1050 pure aluminum in the mixed solution of sulfuric acid:hydrogen peroxide=3:2 (volume ratio) and perform ultrasonic treatment for 2s, wash it with deionized water, and then use 5% sodium hydroxide solution Wash 1050 pure aluminum for 50 seconds, neutralize it with hydrochloric acid to pH 7, and then wash it with deionized water; then form an electrolytic circuit with a graphite electrode under the action of alternating current to obtain a porous surface with a surface roughness Ra of 0.60; after roughening The layout is then cleaned in a hydrogen peroxide solution with a concentration of 2.7M, deashed, washed with deionized water, and then oxidized to form a hydrophilic layer of aluminum oxide; after washing with water, use a concentration of 3 %K2SrF6 aqueous solution ...

Embodiment 2

[0025] A new type of environmentally friendly inkjet CTP plate, which is prepared by the following method:

Abstract

The invention discloses an environment-friendly ink-jet computer-to-plate material. According to the environment-friendly ink-jet computer-to-plate material, a base plate, the manufacturing technology of pigment ink and raw materials are comprehensively optimized, manufacturing is easy and convenient, the pressrun of the manufactured computer-to-plate material is greater than 100 thousands, the light fastness is excellent, and the resolution ratio is high. The manufactured pigment ink does not block a printing head, is stable performance, can be fast attached to a plate base after being printed on the aluminum plate base, does not flow or cause image-text fuzziness, is resistant to water and is high in thermal sensitivity, the plate fixing temperature is low, and the plate fixing time is short.

Description

technical field [0001] The invention belongs to the field of CTP offset printing plates, and in particular relates to an environment-friendly inkjet CTP plate. Background technique [0002] Computer-to-plate (CTP) technology is the most advanced plate-making technology for contemporary offset printing plate-making, and the plates used are called CTP plates. With the development of key technologies such as information and manufacturing, prepress plate-making is making every effort to popularize computer-to-plate (ComputerToPlate, CTP). Computer-to-plate-making refers to the technology of inputting the original information into the computer for processing, and then directly outputting the information to the printing plate through computer control. The information on the electronic layout is transmitted to the printing plate, and the technology for printing the printing plate is obtained directly. Offset printing CTP plates mainly include photosensitive plates, heat-sensitive...
