Artist's proof

An artist's proof is an impression of a print taken in the printmaking process to see the current printing state of a plate while the plate is being worked on by the artist. A proof may show a clearly incomplete image, often called a working proof or trial impression, but in modern practice is usually used to describe an impression of the finished work that is identical to the numbered copies. There can also be printer's proofs which are taken for the printer to see how the image is printing, or are final impressions the printer is allowed to keep.
