Chalcography or chalcography printing is a type of etched printing system. It takes its name from the copper sheets used by early engravers. Today zinc sheets are also used, even if, for hardness, the best material is copper.
The name originates from the Greek words: chalkos rame and grápheim, engraving, writing, in other words the art of engraving on a copper sheet.
Before the advent of this technique, that is, until the mid-fifteenth century, the reproduction of illustrations was done exclusively with the wood inlay technique.
In chalcography, the engraving is carried out on a metal sheet, and the ink deposits in the recesses, that is in the etched parts and not on the relief parts as in wood inlay.
