Printmaking is the process of making artworks by printing, normally on paper. Printmaking normally covers only the process of creating prints with an element of originality, rather than just being a photographic reproduction of a painting. Except in the case of monotyping, the process is capable of producing multiples of the same pieces, which is called a 'print'. Each piece produced is not a copy but considered an original since it is not a reproduction of another work of art and is technically (more correctly) known as an 'impression'. Printmaking (other than monotyping) is not chosen only for its ability to produce multiple copies, but rather for the unique qualities that each of the printmaking processes lends itself to.
Prints are created by transferring ink from a matrix or through a prepared screen to a sheet of paper or other material. Common types of matrices include: metal plates, usually copper or zinc, or polymer plates for engraving or etching; stone, aluminum, or polymer for lithography; blocks of wood for woodcuts and wood engravings; and linoleum for linocuts. Screens made of silk or synthetic fabrics are used for the screenprinting process. Other types of matrix substrates and related processes are discussed below.
Multiple impressions printed from the same matrix form an edition. Since the late 19th century, artists have generally signed individual impressions from an edition and often number the impressions to form a limited edition. Prints may also be printed in book form, such as illustrated books or artist's books.
