Chemical Engraving

Engraving is a process of incising a design on to a hard and surface, by cutting grooves into it. The process of engraving is to decorate object in itself mostly, 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 It has long been replaced by photography in its commercial applications and, partly because of the difficulty of learning the technique, is much less common in printmaking, where it has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.

Chemical engraving is a process similar to photo finishing. A negative of the engraving is scribed on the material. Removing the resulting photographic emulsion from the material leaves the engraving on the material.
