Copper plate acid corrosion process
The whole process is as follows: copper plate (pre - screen printing or photosensitive ink) - etching (common etching solution with ferric chloride series mainly has the advantages of low cost, easy to control, the reaction speed of etching solution can be used repeatedly etc.) - painting or plating or polished or antique old post processing. Brief description of etching effect.
Since it is selective etching, of course, the first step is to distinguish between areas where etching and no etching are required, by plate making, printing, or ink spraying.
Copper corrosion process, called strict etching process, we are usually the etching selective etching, or incised or carved, rather than the whole plate thinning etching.
