Semi-submerged etching laser plate making method

Abstract

The invention relates to a semi-submerged etching laser plate making method. The method comprises the following steps: performing skim coating or spraying on the surface of a copper-plated plate base to form a surface protection glue layer on the surface; then engraving patterns on the glue layer through a laser engraving machine; putting the copper-plated plate base with the patterns into a cleaning tank to perform pre-etching; after pre-etching, putting the copper-plated plate base on a wheel of an etching groove, and turning on a rotating switch to ensure that the copper-plated plate base starts rotating; and then pressing a direction switch to ensure that one third of the surface of the copper-plated plate base is submerged into etching liquid to start etching, and finally obtaining a copper plated plate with required patterns. Compared with the prior art, the semi-submerged etching laser plate making method disclosed by the invention solves the problems that a laser plate has inconsistent mesh points and is non-uniform in etching, dappled etching of the plate surface is too deep or too shallow, and the like.

Description

technical field [0001] The invention relates to a laser plate-making method, in particular to a semi-immersion etching laser plate-making method.

The corrosion time is short, and the corrosion parameters are generally controlled in seconds. The background color version is not easy to control, and the same type of quality problems often occur repeatedly: [0003] 1. Uneven corrosion of large area plate rollers; [0004] 2. The anti-counterfeit or text version of the cigarette label has been corroded; [0005] 3. The layout with many patterns is easy to fade after being corroded; [0006] 4.

AI Technical Summary

Problems solved by technology

[0002] The existing corrosion method is a spray corrosion method. The ferric chloride corrosion solution is filtered and sprayed directly on the layout for corrosion. The corrosion time is short, and the corrosion parameters are generally controlled in seconds. The background color version is not easy to control, and the same type of quality problems often occur repeatedly:

[0003] 1. Uneven corrosion of large area plate rollers;

[0004] 2. The anti-counterfeit or text version of the cigarette label has been corroded;

[0005] 3. The layout with many patterns is easy to fade after being corroded;

[0006] 4. The etching time is short, and the depth of the dots is not well controlled, resulting in poor repeatability of the process parameters of the laser etching plate;

[0007] 5. The pressure of spray corrosion on the dots is soft, and the air pressure turns the ferric chloride corrosion solution into acid mist, which is easy to corrode the glue on the dots

[0008] The repeated appearance of these quality problems seriously affects the production of laser plates and the use of customers

At present, there are many personalized products, and ordinary electronic engraving can no longer meet the needs of personalized products. More customers choose to use laser engraving and corrosion plate-making process to print products, which requires the laser plate-making process to be more stable and the process parameters consistent. sex is higher
