{{Main|Etching}}
Etching is an [[Intaglio (printmaking)|intaglio]] method of [[printmaking]] in which the image is incised into the surface of a metal plate using an acid. The acid eats the metal, leaving behind roughened areas, or, if the surface exposed to the acid is very thin, burning a line into the plate. The use of the process in printmaking is believed to have been invented by [[Daniel Hopfer]] ({{circa|1470}}–1536) of [[Augsburg]], [[Germany]], who decorated armour in this way.

Etching is also used in the manufacturing of printed circuit boards and semiconductor devices.
