One of the four major classes of printmaking. After a metal plate has been incised, ink is dabbed into the lines, the surface is cleaned by wiping, and dampened paper is placed onto the plate. The two are passed through a roller press, which lifts the ink up onto the paper. Engraving, etching, aquatint, stipple, drypoint, and photogravure are forms of intaglio prints. Intaglio is sometimes called copperplate.
