An artistic stamp is an original, as the mould is only created in order to achieve the end result.
The mould , a metal plate (zinc, copper or iron) in chalcography , is engraved with a method defined as "direct" (the tool is guided by the artist's hand and works directly on the plate), or indirect (the artist engraves a wax coating that covers the plate that will be submerged in an acid bath).
The stamp is obtained by inking the engraved marks and cleaning the parts that are not engraved. The mould is then pressed with a printing press against a paper sheet previously wet with a special liquid that helps to preserve over time the finished product.
The high force used to press the mould usually ruins the mould itself, so very few stamps are made with the same mould.

The printed paper is then dryed between two vegetable cartons in order to eliminate any crimples is the paper.Every stamp is then numbered and autographed by the artist.

Numbering is achieved with two numbers: the first defines the progressive number of stamps, while the second number defines the total number of prints.

The mould is then destroyed, as an added guarantee that the number of examples are those indicated.
