Edition - Numbering

Numbering

Because of the variation in quality, lower-numbered prints in an edition are sometimes favored as superior, especially with older works where the image was struck until the plate wore out. However the numbering of impressions in fact may well not equate at all to the sequence in which they were printed, and may often be the reverse of it.

In later times, printmakers recognized the value of limiting the size of an edition and including the volume of the edition in the print number (e.g., "15/30" for the 15th print in an edition of 30). Tight controls on the process to limit or eliminate variation in quality have become the norm. In monotyping, a technique where only two impressions at most can be taken, prints may be numbered 1/1, or marked "unique". Artists usually print an edition much smaller than the plate allows, both for marketing reasons and to keep the edition comfortably within the lifespan of the plate. Specific steps may also be taken to strengthen the plate, such as electroplating intaglio images, which uses an electric process to put a very thin coat of a stronger metal onto a plate of a weaker metal.

The conventions for numbering prints are well-established, but other marks may indicate that a print has been made in addition to the numbered prints of an edition. Artist's proofs are marked "A. P." or "P/A", sometimes E. A. or E. d'A. (épreuve d'artiste); monoprints and uniquely hand-altered prints are marked "unique"; prints that are given to someone or are for some reason unsuitable for sale are marked "H. C." or "H/C", meaning "hors de commerce", not for sale. These are usually prints reserved for the publisher, like Artist's Proofs. The printer is also often allowed to retain some proof impressions; these are marked "P. P." Finally, a master image may be printed against which the members of the edition are compared for quality: these are marked as "bon à tirer" or "BAT" ("good to print" in French). In all, the number of the main edition can represent 50% or less of the total number of good impressions taken.
