Engraving is putting a design onto a hard, flat surface, by carving into it. The result may be a decorative piece in itself, as when silver, gold or steel are engraved, or may provide a printing plate of copper or another metal, for printing images on paper which are also called engravings. Engraving was an important method in history of making images on paper, both in artistic ways, such as making a decorative print, and also for printing books and magazines. It has long been replaced by photography in its commercial uses and, is nowadays much less common in printmaking, where it has been almost completely replaced by etching and other techniques.
