Bon à Tirer (B.A.T.)
Literally "ready to pull," the B.A.T. is the final trial proof - approved by the artist - which tells the printer exactly how the edition should look. Each impression in the edition is matched to or modeled after the B.A.T. This proof is used principally when someone other than the artist is printing the series. There is only one of these proofs for an edition.
