Abstract

The invention discloses a digital screening flexographic preprinting method for a wide color corrugated carton. The method comprises a wide color corrugated carton flexographic preprinting method and a digital screening method, and the digital screening method comprises rasterization calculation and a flexographic screen dot generation system. The flexographic screen dot generation system comprises a compression screen dot restoration tool, flexographic screen dots, a screen dot application tool, a rapid manuscript comparison printing tool and a color management tool. Wherein the flexographic screen dots are selected from one or more of honeycomb-shaped dots, star-shaped screen dots, T-shaped screen dots, chain-shaped dots, variable-frequency screen dots and hierarchical screen dots. The digital screening flexographic preprinting method has the advantages that the printing effect is improved, the printing problem is solved, ink consumption is reduced, and printing waste is reduced.

Description

technical field [0001] The invention relates to a digital screen flexographic pre-printing method for wide-width color corrugated cartons. Background technique [0002] The traditional method in the flexographic plate making method is the photoflexo plate making method. The mesh area of ​​the printing plate made by the method is the same, and the layers of the printed matter are expressed by different mesh depths. The original version has no dots and is a continuous tone film. The image on the original plate is imaged on the corrosion-resistant film (the film used to corrode the coating of the printing plate cylinder) or carbon paper after ultraviolet irradiation, and then the film is wrapped on the cylinder, developed in warm water, and chemically processed by ferric chloride. Corrosion, forming meshes of different shades. Nowadays, the continuous tone original carbon paper is mostly not used, and the method of color separation film is mainly used, that is, the method of...
