As we know, the idea of limited editions is derived from etchings and lithographs where the plate or stone was degraded by the wear of the printing process. No such wear occurs with negatives or digital files and, as a result, the great innovators of print sales, including, among many others, Edward Weston, Alfred Steiglitz, Ansel Adams and Henri Cartier Bresson did not limit their editions.
Some years ago, galleries discovered that collectors were willing to pay more for a collectible print in a limited edition. This leads me to some questions:
Are you selling or expecting to sell through galleries? If so, what are the policies of those galleries?
Are you selling to collectors who are expecting (hoping?) that the print will increase in value or will at least maintain its value?
Is the edition size so large that it doesn’t really affect value?
Are you prepared to keep records so that you don’t exceed the edition size?
Would your buyers be annoyed if they saw the same image in an advertisement or nicely printed poster?
Just to make things more complicated, some localities have consumer protection laws that define “edition”. For example, are a 11x14 print and a 16x20 print part of the same “edition” or are they in different “editions” because the size is different. You’ll need to check in the locality where you are selling.
