On my work ,I mostly use technique called 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. Once printed onto its paper support, the etching's design appears in reverse of the original on the plate. The pressure of the press not only forces the ink onto the damp paper, but also produces an outline of the outer edges of the metal plate in the paper, known as a plate mark.
