Plate making process of intaglio roller

Abstract

The invention belongs to the field of plate making processes, and relates to a plate making process of an intaglio roller. The process comprises the steps of plate roller processing, optical cement manufacturing, pre-plating layer electroplating, engraving layer electroplating, engraving layer polishing, optical cement covering, laser ablation, ink cell cleaning, dot corrosion, optical cement removal and reinforcing layer electroplating, a plate cylinder base body adopts a seamless steel pipe, the weight is 10-300KG, the wall thickness of the steel pipe is 10-30MM, the optical cement comprises 1%-15% of fired resin, 1%-15% of an adhesion promoter, 1%-15% of black color paste, 30%-70% of a solvent, 1%-3% of a plasticizer, 1%-3% of a leveling agent and 1%-3% of a defoaming agent, and the fired resin comprises nitrocotton and rosin. According to the process, plate making can be more accurate, the manufactured plate roller is smooth in surface, small in circumferential deviation and durable, meanwhile, a U-shaped dot is adopted, compared with a V-shaped dot and a prismatic dot, the ink content is larger, an ink layer is thicker, and the color is brighter.

Description

technical field [0001] The invention belongs to the field of plate-making technology, and in particular relates to a plate-making process of gravure plate rollers. Background technique [0002] Gravure printing is to make the entire surface of the printing plate be covered with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only stays in the cells of the graphic part, and then under the action of greater pressure , transfer the ink to the surface of the substrate to obtain printed matter. Gravure printing belongs to direct printing. The graphic part of the printing plate is concave, and the degree of depression varies with the level of the image, and the blank part of the printing plate is raised and on the same plane. The plate making process of the gravure roller directly affects the printing effect. [0003] The traditional gravure roll plate making method mainly uses mechanical pressure roll, electronic engraving an...

Problems solved by technology

[0004] The invention provides a plate-making process of a gravure plate roll, which is used to solve the problem that the surface of the plate-making roll in the existing plate-making process is not smooth, the circumference is irregular, and the characters, lines, and solid edges engraved with prismatic dots will inevitably have some "jaggies" Shaped dots problem
