(1) Metal etching processThe type of metal is different, the etching process is also different, but the general process is as follows: metal etching plate → degreasing → water washing → etching → water washing → drying → screen printing → drying → water immersion for 2~3min → etching pattern Text →

Gravure printing is to fill the entire surface of the printing plate with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only remains in the cells of the graphic part, and then under greater pressure ,Transfer the ink to the surface of the substrate to obtain printed matter.
