An artist’s proof, often marked A.P. or the French Épreuve d’Artiste (E.A.), is a finished print that the artist sets aside outside the main numbered edition. By convention these impressions are often limited to about 10 percent of the edition size, though artists vary that practice. An AP usually matches the edition prints in quality, so it rarely changes the print’s value on its own.
TL;DR:
- An edition of 100 contains 100 numbered prints plus separately tracked proofs; the customary guideline is roughly 10 artist’s proofs, but practices vary.
- Look for an artist’s proof notation in pencil, the artist’s signature, and no standard edition fraction; a working proof may show unfinished changes.
- A printer’s proof belongs to the printer, while an approved reference proof guides production; trial proofs can differ in color or detail.
- Before paying extra, request publisher or gallery records, compare condition, verify the signature, and ask what evidence supports any premium beyond the label.

What exactly an artist’s proof is and how it’s marked
The term goes back to a simple studio practice: before editions were sold, artists kept a small number of impressions for themselves, for records, exhibitions, or gifts. That habit stuck, and today a finished artist’s proof is typically identical in paper, ink, and image quality to the numbered prints in the edition. The GVSU Art Museum glossary confirms that an AP is excluded from the main numbered run but otherwise counts as a completed, sellable impression.
You can usually spot an artist’s proof by its margin markings:
- “A.P.” or “Épreuve d’Artiste” written in pencil near the image, often followed by a number such as “A.P. 3/10”
- A pencil signature from the artist, placed the same way it would appear on a numbered print
- No fraction like “24/100” since APs sit outside the edition count
It helps to separate a finished artist’s proof from an earlier working or trial proof. A working proof is pulled while the artist is still adjusting the image and can look rougher or different from the final version, while a true artist’s proof is a completed, edition-quality impression kept apart from the numbered set.
How APs differ from numbered edition prints and edition-numbering conventions
A numbered print carries a fraction like “14/100,” where the first number is that print’s position in the production order and the second is the total edition size. Neither number ranks quality: print 14 is not better or worse than print 90, since all prints in the run are pulled from the same plate or screen under the same conditions.
Artist’s proofs sit outside that count entirely. If an edition is listed as “100,” the published run contains 100 numbered prints plus whatever proofs the artist or printer set aside.
- Edition size and AP count are tracked separately, so “100” never includes the proofs
- A customary guideline caps artist’s proofs at roughly 10 percent of the edition, meaning an edition of 100 might include around 10 APs, though some artists pull more or fewer
- Because APs are a small, separate group, some collectors treat them as marginally scarcer, even when the image and materials are the same as a numbered print
This exclusion from the main count is a labeling convention, not a quality distinction. A numbered print and an artist’s proof pulled from the same run are typically the same object in every way that matters to how the image looks and holds up over time.
Other proofs you’ll see explained: trial proof, printer’s proof, bon à tirer, hors commerce
Catalog notes and gallery labels use several proof terms that confuse new buyers. Curatorial glossaries from the Getty Research Institute and the IFPDA glossary lay out the main categories:
- Trial or working proof: pulled during development, before the image is finalized, and can differ in color or detail from the eventual edition.
- Bon à tirer (B.A.T.): the single approved proof that becomes the production standard. The printer matches every edition print to this one reference.
- Printer’s proof (P.P.): an impression the printer keeps as compensation or for records, separate from the artist’s own proofs.
- Hors commerce (H.C.): literally “not for trade,” these proofs are generally not intended for sale and are used for exhibitions, records, or display.
- State proof: a proof pulled at a specific stage of the plate or block’s development, used to document changes between states.
Each label tells you something about where that specific impression came from in the production process, not whether it is more valuable by default.
What AP status typically means for value and what to ask before paying more
Dealers and collectors often view artist’s proofs as a slightly more personal category, tied to the artist’s own records rather than the commercial run, and that association sometimes supports a modest premium. But a premium is not automatic. When an artist’s proof and a numbered print share identical materials, condition, and signature, many buyers and sellers treat them as equivalent in the open market.
Before paying more for an AP, it helps to verify a few things:
- Ask for documentation tying the specific impression to the artist or publisher’s records
- Compare condition against numbered prints from the same edition, since foxing, fading, or trimming affects value regardless of proof status
- Confirm the pencil signature matches known examples and appears in the expected location
- Check whether the gallery or auction house can point to a publisher’s archive or exhibition history for that impression
Pro Tip: Ask the seller directly whether the “proof” label reflects a true artist’s proof excluded from the edition count, or just a promotional term, since the ILAB explainer on proof prints notes that “proof” has sometimes been used loosely in commercial listings with little consistent meaning.
A practical checklist to verify an AP on a gallery label or auction listing
Use this short sequence when you are looking at a specific print and want to confirm its AP status before buying.
- Read the margin markings carefully: look for “A.P.,” “E.A.,” or a proof fraction instead of a standard edition number.
- Confirm the pencil signature is present and consistent with other known signed works by the same artist.
- Ask the seller for provenance records, such as a publisher’s invoice, gallery consignment paperwork, or archive confirmation.
- Request a condition report, especially for older prints, since paper toning or trimming can affect both value and authenticity claims.
- When the price carries a significant premium over numbered prints from the same edition, ask what specifically justifies that gap beyond the AP label itself.
Collectors buying editioned works in other mediums face a similar task. The verification checks used for numbered edition statues follow the same logic: documentation and condition matter more than a label alone.
How printers use proofs in production: a Print Cafe USA perspective
In our own production work, proofs exist to lock in quality before a job runs at scale. A bon à tirer style approval, where a client or artist signs off on a reference proof, keeps every piece in a run consistent with what was approved, whether that run is a fine art edition or a commercial print job. We rely on proofing steps like color proofs and press checks to catch issues before full production, which is the same quality-control logic behind a printer’s proof in fine art editioning.
A few things a reputable printer or studio should be able to provide buyers:
- A record of when the reference proof was approved and by whom
- Documentation showing how many proofs were pulled outside the main run
- Confirmation of the materials and process used, since that affects both appearance and longevity
We cover more of this process in our piece on print proofs in flawless production.
A print professional’s view on provenance and proofs
Proofs exist because artists and printers have always needed a reliable reference point before committing to a full run. That tradition still matters, but a label in the margin is not proof by itself. Ask for the paperwork behind it, and treat a well-documented artist’s proof as a good sign, not a shortcut past verification.

FAQ
What does A.P. mean on a print?
A.P. stands for artist’s proof, an impression the artist kept outside the main numbered edition. It is usually identical in quality to the numbered prints from the same run.
Are artist proofs more valuable than numbered prints?
Not automatically. Some buyers pay a modest premium for the association with the artist’s personal records, but when materials, condition, and signature match a numbered print, many in the market treat the two as equivalent.
What is the difference between a proof and a regular print?
A regular print carries a fraction like 14/100 showing its place in the numbered edition, while a proof, such as an artist’s proof or printer’s proof, sits outside that count. The IFPDA glossary outlines how these categories differ by purpose rather than quality.
How many artist proofs are typically made for an edition?
There is no fixed rule, but a common guideline keeps artist’s proofs around 10 percent of the edition size. Some artists produce more or fewer depending on personal practice.
How can I confirm a print labeled “artist proof” is genuine?
Check the margin markings, pencil signature, and ask the seller for provenance or publisher documentation. Loose or inconsistent use of the word “proof” in commercial listings is common enough that the ILAB guide to proof prints recommends confirming paperwork rather than relying on the label alone.
