Acid Etching
Acid etching, from the German word meaning “to eat,” is cutting into a surface of a material using acid. The method of etching on metal can be a chemical process using acid, a photochemical process, or an electrochemical process. The basic technique for acid metal etching is to apply a resist to the areas of a metal plate, either to the whole plate or just to the areas that one wants to remain unaffected.
