A numbered print which is not part of the limited edition. Usually these prints are signed "Artist Proof" or "AP" with the generally accepted edition size not to exceed ten percent of the regular limited edition size. (ie: an edition of 500 would have 50 artist proofs.) With modern printing, artists proofs are not better quality prints than the regular edition, however they are desirable to many serious collectors in that there are fewer signed in this way. Many artist proofs are remarqued to make them even more valuable.
An early 'proof' of an artist's printing plate (e.g., copper or zinc plate for an etching). The artist proof is essentially the first satisfactory print that defines when an artist determines a plate 'finished' and ready for printing in a full edition.
