A general term for metal-plate printmaking techniques, including etching, drypoint, engraving, aquatint, and mezzotint. The word comes from the Italian intagliare, meaning “to incise” or “to carve.” In intaglio printing, the lines or areas that hold the ink are incised below the surface of the plate, and printing relies on the pressure of a press to force damp paper into these incised lines or areas, to pick up ink.
