Intaglio

The collective term for several graphic processes in which prints are made from ink trapped in the grooves in an incised metal plate. Etchings and engravings are the most typical examples. It may also refer to imagery incised on gems or hardstones, seals, and dies for coins, or to an object decorated in this way; which when pressed or stamped into a soft substance, produces a positive relief in that substance.
