Engraving is the practice of incising a design on to a hard, usually flat surface, by cutting grooves into it. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called engravings.
Engraving was a historically important method of producing images on paper, both in artistic printmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning the technique, is much less common in printmaking, where it has been largely replaced by etching and other techniques.
Traditional engraving, by burin or with the use of machines, continues to be practised by goldsmiths, glass engravers, gunsmithsand others, while modern industrial techniques such as photoengraving and laser engraving have many important applications.Engraved gems were an important art in the ancient world, revived at the Renaissance, although the term traditionally coversrelief as well as intaglio carvings, and is essentially a branch of sculpture rather than engraving, as drills were the usual tools.
