Gravure printing plate and manufacturing method of gravure printing plate

Abstract

The invention belongs to the technical field of dry etching, and particularly relates to a gravure printing plate and a manufacturing method of the gravure printing plate. The gravure printing plate comprises a frame body, an etching box and feeding frames, wherein the feeding frames are fixedly connected to the two sides of the frame body and are symmetrically designed, the feeding frames are obliquely arranged, the etching box is fixedly connected with the frame body through the feeding frames, sliding grooves are formed in the upper surface of the feeding frames, symmetrically-designed first sliding grooves are formed in the two sides of the etching box, the first sliding grooves and the sliding grooves are designed to communicate with each other, the first sliding grooves are designedto penetrate through the etching box, rotating grooves which are symmetrically designed are formed in the side wall of the etching box, the rotating grooves are used for containing printing plate rollers, a first groove is formed in the bottom of the rotating groove, the first groove is designed to be T-shaped, a supporting plate is elastically connected into the first groove, an electric push rodis fixedly connected to the bottom of the first groove, the rotating grooves communicate with the first sliding grooves, and the etching box is provided with a second sliding groove and a third sliding groove at the bottom of the first sliding grooves.

Description

technical field [0001] The invention belongs to the technical field of dry etching, in particular to a gravure printing plate and a method for manufacturing the gravure printing plate. Background technique [0002] The printing plate is referred to as the printing plate. Carriers used to transfer ink to printed images on substrates can be divided into four types: letterpress, gravure, lithographic, and stencil. Banknote products refer to banknotes and securities, which have a large printing volume and are resistant to printing plates. higher requirements. For a long time, my country's banknote printing has widely used a double-layer or multi-layer metal structure printing plate with extremely high printing resistance. The printing resistance of offset printing plates with this structure is stable above 1.5 million impressions. The production method of this printing plate mainly adopts the method of chemical etching at present, and the basic technological process is as foll...

AI Technical Summary

Problems solved by technology

[0003] In order to make up for the deficiencies of the existing technology, the existence of the air pump in the etching process makes the flow rate of the chemical gas inside the etching box different, and the difference in the activity of the reactants in the center of the upper electrode plate and the surrounding reactants is likely to cause different etching uniformity, resulting in The problem of poor etching effect, a kind of gravure printing plate and the manufacturing method of gravure printing plate proposed by the present invention
