Proof

An impression outside the edition, usually pulled during the process of working a plate. Types of proofs include:

Bon a Tirer:
(B.A.T) French for “good to pull” and so signed by the artist as the proof that meets his/her aesthetic and technical standards. It is used as a guide against for the master printer to print the edition from.

Artist's Proof:
(A.P) these rarely exceed 10% of the edition, although this figure can be higher, in which case they may be deemed a “Proof Edition” and usually numbered in Roman numerals. These prints are intended for the artist's personal use and are normally identical to the edition prints. The artist's proof is sometimes known by its French name, Epreuve d'artiste.

Trial Proofs:
(T.P.) in black and white or colour proofs (C.P.) have minor variations in the image, pulled as the artist refines the work just before arriving at the B.A.T.

Instate Proofs:
(I.S.) there may be any number of state proofs. These involve substantial changes made before the final edition is pulled, and often show major stages in the development of the image. The difference between states is sometimes so great that separate editions are sometimes made from instate proofs during the developmental stages of making a plate. When the artist feels reasonably satisfied with the print at a completed stage, yet wants to take it further, he pulls an instate edition in recognition that continual work on the plate may destroy it.

Special Proofs:
(S.P.) Similar to Artist Proofs but may have a subtle difference or printed specially for the artist or printer.

Progressive Proofs:
are a series of impressions made for a multicolour print, showing each colour separately and in combination with each of the other colours.

Presentation Prints:
are usually equal in quality to the prints of the edition and are dedicated to an individual. They are normally hors commerce (H.C.) (“not for sale”), although they occasionally find their way onto the market.

Printer's Proofs:
(P.P.) are given to the printer who collaborated with the artist and/or printed the edition. They may be dedicated personally or simply marked Printer's Proof.

Cancellation Proof:
An impression taken from a stone, block or plate after it has been effaced at the end of the run is called a Cancellation Proof. This indicates that no further prints can be made.
