Abstract

The invention relates to the technical field of printing technologies, in particular to an environment-friendly printing technology. The environment-friendly printing technology includes the followingsteps that a printing plate is obtained after treatment of film forming, proof making, makeup and plate burning according to specifications of printed objects; the printing plate is fixed to a printer after dampening treatment, and compound ink is poured into the printer; and paper after inertia treatment is fed into the printer to print and a printed object is obtained, and a printing technologyfinished product is obtained by post-press processing. The environment-friendly printing technology adopts a fountain solution without alcohol and the compound ink. The compound ink is prepared fromthe components in parts by weight: 4-9 parts of pigments, 30-50 parts of episulfide resins, 3-5 parts of ethyl acetate, 4-6 parts of dicyandiamide, 4-8 parts of triolein, 1-4 parts of oxalate, 1-4 parts of magnesium sulfate, 3-7 parts of protein powder, 2-6 parts of beeswax, 20-30 parts of an auxiliary assistant, 1-4 parts of a dispersant and 70-80 parts of deionized water.

Description

technical field [0001] The invention relates to the technical field of printing technology, in particular to an environmentally friendly printing technology. Background technique [0002] The printing industry is a huge industry system, but also an industry system with a long history. Since the invention of printing in ancient China, the printing quantity and quality of books have been advancing with the times. It is with the development of the times that more and more fields need to use printing technology. Printing technology is not just a traditional one. It is just a technology that serves books, whether it is the current posters, advertisements, promotional products, etc., or ceramics, wood products, and metal products, it will involve the surface printing of utensils, which not only puts forward higher requirements for printing machines , How to keep the printed patterns and characters for a long time will have higher requirements for the printing process and the ink ...
