Unlike … WebEtching. Etching is an intaglio printmaking process in which lines or areas are incised using acid into a metal plate in order to hold the ink. In etching, the plate can be made of iron, copper, or zinc. To prepare the plate for etching, it is first polished to remove all scratches and imperfections from the surface.
WebAlthough water can be used as a diluent, acetic acid is preferred as the dissociation of nitric acid can be retarded in order to yield a higher concentration of the undissociated species. At very high HF and low HNO 3 concentrations, the etching rate is controlled by HNO 3, because there is an excess amount of HF to dissolve any SiO 2
