The art of engraving has been practiced from the earliest ages. The prehistoric Aztec hatchet given to Alexander von Humboldt in Mexico was just as truly engraved as a modern copper-plate which may convey a design by John Flaxman; the Aztec engraving may be less sophisticated than the European, but it is the same art form.
In intaglio printing, the lines to be printed are cut into a metal (e.g. copper) plate by means either of a cutting tool called a burin, held in the hand – in which case the process is called engraving; or through the corrosive action of acid – in which case the process is known as etching. [6] [7]
Other terms often used for printed engravings are copper engraving, copper-plate engraving or line engraving.

Gravure cylinders are usually made of steel and plated with copper, though other materials, e.g. ceramics can also be used. The desired pattern is achieved by engraving with a laser or a diamond tool, or by chemical etching. If the cylinder is chemically etched, a resist (in the form of a negative image) is transferred to the cylinder before ...
The process of stipple engraving is described in T.H. Fielding's Art of Engraving (1841). To begin with an etching "ground" is laid on the plate, which is a waxy coating that makes the plate resistant to acid. The outline is drawn out in small dots with an etching needle, and the darker areas of the image shaded with a pattern of close dots.
