Abstract

The invention relates to a printing plate-making technology, and particularly relates to a transparent film for waterproof inkjet printing plate-making for the printing plate-making industry. The technical problem to be solved is to provide a transparent film for waterproof inkjet printing plate-making for the printing plate-making industry, which is good in waterproof effect, fast in speed and clear in screen points. The invention provides a transparent film for waterproof inkjet printing plate-making for the printing plate-making industry. The film is provided with a single coating; and the emulsion of the coating comprises polyvinyl alcohol having a main material polymerization degree of 6000-8000 and an alcoholysis degree of 78%, and a nano-scale granulated silica dispersion having a mass concentration of 40%. The product disclosed by the invention is fast in speed in an application process, clear in screen points, reliable in performance, and quite remarkable in effect. The product disclosed by the invention is reasonable in formula, efficient and environment-friendly, capable of filling in the domestic blanks, capable of being widely applied to the advertising industry and the printing plate-making industry, simple in process, and convenient to operate.

Description

technical field [0001] The invention relates to a printing plate-making technology, in particular to a waterproof ink-jet printing plate-making transparent film used in the printing plate-making industry. Background technique [0002] At present, the traditional laser phototypesetting film has the characteristics of high resolution and high density, but its cumbersome darkroom operation makes the overall cost of printing and plate making high, and the waste liquid caused by the processing process is polluting. With the continuous improvement of inkjet printing technology, especially the application of piezoelectric technology, the output accuracy and width of inkjet printing equipment have been continuously improved, which makes the application field of inkjet printing technology gradually shift from the past advertising output field to digital The image output field and the printing field expand, especially its convenient, fast, and environmental protection features, which ...
