general use: ca. 1880-present
Description: A photomechanical printing process, the print is made from a metal plate like an etching or engraving, using ink to form the image. A plate is made light sensitive, exposed to a negative, and then etched in acid. It was originally favored because it was possible to make large numbers of permanent images of consistent quality. This term is also used to describe some commercial printing processes which utilize screens with a pattern of dots. In the process referred to here, there is no such pattern.
