Limited edition Artist original Prints including: Etchings, Screenprints, Collagraphs, Lithographs and combined hand printed techniques. 

As a guide, limited edition prints are exactly that, i.e. limited. The limit is basically a factor of the process. Editions printed by the artists themselves generally have lower numbers in the edition, compared to when a master printer is used to print the artist prepared materials.

Generally etchings, relief (wood and lino-cut prints), collagraphs, lithographs are limited at 30, or less in the edition where the artist is the printer, with a 10% (of the edition number) Artist Proof (A/P) made . These Artist proofs are identical to the edition.

Screen prints are generally limited to 99 in the edition or less as the artist printmaker decides, except in situations such as the Nimrod Theatre posters numbered and signed by Martin Sharp where a (pre-digital printer era) commercial screenprinting workshop was used

As a general guide, artist printed editions of any traditional technique rarely exceed 99 in number without serious technical intervention in the process. For example: steel plating the face of an etching plate to prevent it wearing out before the edition is completed. This is the province of the Master Printer and their Print Workshop staff.

Drypoint etchings are generally very limited editions because the metal curl from the hand scribing of the image into the plate that then holds the ink in the inking up  process before printing simply breaks down very quickly and each print is therefore very subtly different.

An original artist (in computer) created digital print is one that is made by the artist and completely conceived and executed in-computer without any contributing source files that reproduce, amend, etc., an art work originally created in another medium and then incorporated into the digital process. 

"An original artist print is not a signed digital/giclee reproduction and/or signed poster that reproduces an original art work made in another medium."
