Prints on paper incorporating impressions of a reverse design created on a printing plate, usually copper, into which the design has been incised (engraved) using burins or gravers. Historically, "engravings" has sometimes been incorrectly used to refer to all prints, regardless of the specific technique. For prints made from designs engraved on a flat wooden block, use "wood cuts"; for prints made from a plate that is etched rather than engraved, use "etchings.
