A proof is an impression of a print pulled prior to the regular, published edition of the print. A trial or working proof is one taken before the design on the matrix is finished. These proofs are pulled so that the artist can see what work still needs to be done to the matrix. Once a printed image meets the artist’s expectations, this becomes a bon tirer (“good to pull”) proof. This proof is often signed by the artist to indicate his approval and is used for comparison purposes by the printer. An artist’s proof is an impression issued extra to the regular numbered edition and reserved for the artist’s own use. Artist’s proofs are usually signed and are sometimes marked “A.P.”, “E.A.” or “H.C.” (Cf. glossary of abbreviations) Commercial publishers found that there was a financial advantage to offering so-called “proofs” for sale and so developed other types of proofs to offer to collectors, generally at higher prices.

  • Proof before letters (Avant les lettres): An impression pulled before the title is added below the image.
  • Scratched letter proof: An impression in which the title is lightly etched below the image.
  • Remarque proof: An impression pulled before the remarque is removed.
