Engraving as a technique, is an antique printing process, for which a plate made of zinc or copper is engraved by hand, then the plate is printed on cotton paper using a printing press. Etching, aquatint, dry point, soft wax and mezzotint are some of the better-known methods used. Once the etching is terminated, it is inked, and then pressed in between two rollers, which transfer the image to the moistened paper. After the drying is terminated each copy is numbered and signed by the author to indicate its edition and authenticity.
