An Edition in Artwork Archive is used as a set of original works of art intended for graphic reproduction and produced by or under the supervision of the artist who designed it. These are images or casts that are produced to be multiples.
Examples of editions: etchings, lithographs, fine art photography prints, bronze castings, etc.
Editions are most often done completely by the artist and made in small runs. Each work in the edition has unique qualities and can vary slightly because each one is created individually.
A Reproduction in Artwork Archive is considered a copy/facsimile of the original work usually created using photomechanical means. Producing a reproduction does not typically involve the original artist. Usually, a digital image is created of the work, and that file can then be used to reproduce it on any surface in any size.
Examples of reproductions: giclee prints, iris, posters, print as a service item such as pillows & garments, cards, etc.
Note: Editions count against your piece count in your plan. Reproductions do not. However, reproductions have limitations—you can not include them in reports, certificate of authenticity, or build location and show history.
