This article is about techniques of printmaking as a fine art
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 piece, 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 from a single original surface, known technically as a matrix. Common types of matrices include: plates of metal, usually copper or zinc for engraving or etching; stone, used for lithography; blocks of wood for woodcuts, linoleum for linocuts and fabric plates for screen-printing. But there are many other kinds of matrix substrates and related processes. Click on above Wikipedia link for more info on the topic of Printmaking.
