A semi-immersion etching laser plate-making method

Abstract

The invention relates to a semi-immersed etching laser plate-making method. The surface of the copper-plated plate base is glued or sprayed to form a layer of surface protection glue layer on the surface, and then the pattern is engraved on the glue layer by a laser engraving machine. The copper-plated base of the pattern is placed in the cleaning tank for pre-etching. After the pre-corrosion, the copper-plated base is placed on the wheel of the corrosion tank. One part of the surface is immersed in the etching solution to start corrosion, and finally a copper plate with the desired pattern is obtained. Compared with the prior art, the present invention solves the problems of uniformity of dots and uneven corrosion of the laser plate, deep and shallow corrosion of patterned pages, 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. Background technique [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. Spray corrosion puts a ...

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. Spray corrosion puts a lot of pressure on the dots, 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 individual 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
