Engraving
A print produced by a method in which lines are cut into a copper or metal plate with a cutting tool called an engraver or burin, leaving a tiny trench which is later filled with ink. It is these lines that show as the final image on the print. Ink is applied to the plate and a print is taken after the plate has been wiped to leave ink the engraved lines only. This term is also used generically to cover all methods of producing prints by the intaglio process.
