"Intaglio (/ɪnˈtælioʊ/ in-TAL-ee-oh, Italian: [inˈtaʎʎo]) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. It is the direct opposite of a relief print.
Normally, copper or zinc plates are used as a surface or matrix, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint. Collagraphs may also be printed as intaglio plates." - (en.wikipedia.org 19.11.2019)
