Finished CNC Copper Plate
The art of copper plate etching is elegant and solemn, simple and generous, and has a strong artistic charm. The copper plate etching process usually is an selective etching either print etching or anode etching, rather than thinning etching of the entire plate. Of course, since it is selective etching, the area that needs to be etched and the area that does not need to be etched should be distinguished by lithography or inkjet and development.
