Art print certificate of authenticity on Shopify

What does a print COA traditionally include?

Galleries and print publishers have converged on a fairly standard set of fields for paper COAs. A digital COA includes the same data, optionally with more:

• Artist name (and sometimes the studio name)
• Title of the work
• Edition number in [number]/[total] format (15/75, or 15 of 75)
• Year of the print run
• Medium and print method (giclée on cotton rag, four-color screen print, etc.)
• Paper (Hahnemühle Photo Rag 308gsm, Somerset Velvet 280gsm, etc.)
• Dimensions (image size and paper size)
• Signature on the print itself (not just the certificate)
• Studio location and publication info
• A signed and dated statement from the artist or the publisher

For digital COAs, the hosted page can include high-resolution images of the print, a video of the printing process, the chain of custody, exhibition history, and any other context that would be cumbersome on paper. The print-specific pattern fits inside the broader provenance certificates pattern that covers every numbered-product category.

What is the convention for numbering art print editions?

Conventions vary by genre, but the most common pattern:

• Number every print in the run with a pencil notation on the print itself, in the format "15/75" or "15 of 75", traditionally written below the image on the lower-left corner
• Artist signature in the lower-right corner, also in pencil
• Print title (if used) in the lower-center
• Edition total is fixed at the start of the run and not exceeded
• Artist's Proofs (AP) are typically counted separately, marked AP 1/10 or similar, and are not part of the numbered run
• Printer's Proofs (PP), Hors Commerce (HC), and other variants exist for specific use cases

The digital COA echoes the print itself: same numbering, same edition total, same artist signature reference. The COA does not replace the pencil notation on the print. It documents and verifies it.

Why do galleries expect a COA?

Three practical reasons:

1. Resale value depends on it. A print in the secondary market without a COA sells for less. Sometimes much less. The COA is part of the asset.
2. Insurance and customs. For pieces that travel, the COA is the documentation that justifies the insured value and the customs declaration.
3. Estate planning and inheritance. Prints get passed down. A COA travels with the piece across generations and confirms what the piece is without anyone having to track down the original artist or publisher.

What is the digital COA workflow on Shopify?

The flow most artists running on Shopify use:

1. Artist sets up the edition on Shopify: a single product with a fixed total (let us say 75)
2. Storefront shows an edition badge ("Edition of 75") and a scarcity bar that updates with each sale
3. Buyer purchases. The numbered-edition app auto-assigns the lowest available number (let us say 12)
4. The buyer's order confirmation includes "Your edition: 12 of 75" and a preview of the certificate
5. Artist signs and numbers print 12 in pencil before shipping
6. Print ships with a printed COA card. Card has the artist name, title, edition number 12, year, medium, paper, dimensions, and a QR code resolving to the hosted certificate page
7. Buyer scans the QR. Lands on the hosted page on the artist's own Shopify domain (no third-party). Sees verified status, high-resolution image of the print, signed statement from the artist
8. Buyer files the COA card with their other documentation. The hosted page lives on the merchant's domain as the durable record

Should the COA include the print's image?

Yes. The hosted certificate page should show the image of the print so the COA cannot be ambiguously associated with a different work. A buyer should be able to look at the hosted page and the print side by side and confirm they match.

Print the QR code only on the card, not on the print itself. The print is a finished artwork. The card is the documentation.

What about Artist's Proofs and other non-edition prints?

Artist's Proofs (AP), Printer's Proofs (PP), and Hors Commerce (HC) prints are usually issued as a separate small set outside the numbered edition. Common patterns:

• For an edition of 75, an artist might issue 5 to 10 APs, numbered AP 1/10 through AP 10/10
• APs are traditionally retained by the artist or used for promotional purposes
• PPs are retained by the printer
• HC prints are non-commercial copies

If you sell APs, they should have their own COA workflow. A Shopify numbered-edition app should let you set up the AP set as a separate product (or a separate edition mode on the same product) so the numbering does not conflict with the main run.

What does the certificate page actually need to show?

A clean hosted COA page for an art print typically shows:

• A high-resolution image of the print at the top
• Title of the work in large display type
• Artist name and signature representation
• Edition number in display type ("12 of 75")
• Medium, paper, print method, dimensions in a clean spec block
• Year and date of issue
• A signed statement from the artist or publisher
• Verified status with a timestamp ("Verified by hashed visitor ID, May 2026")
• Studio and contact information

Pages on a Shopify-hosted certificate stay live for as long as the merchant runs the store. The buyer can return to the URL years later and the page will still resolve.

What about resale and provenance over decades?

For art, the COA needs to outlast the original transaction by many years. Three considerations:

• The certificate URL should live on the artist's own domain. Not a third-party platform that might shut down. Editioned hosts the certificate page on the merchant's Shopify storefront via a theme app extension, so the URL is on the artist's domain.
• The certificate should survive ownership transfer. When the print is sold by the original buyer to a new owner, the same certificate URL should still work. The certificate is anchored to the piece, not to a specific account.
• The artist or publisher should be able to revoke certificates when needed. If a print is destroyed, returned, or stolen, the certificate should be revocable. This is the same revocation pattern that applies in jewelry and streetwear.

How does this compare to NFT prints?

Some artists tried NFTs alongside physical prints from 2021 to 2023. The pattern that emerged:

• Buyers in the art market are older, on average, than buyers in streetwear or sneakers
• Wallet onboarding was an even bigger friction in this segment than elsewhere
• The NFT did not increase the print's resale value at gallery scale; it sometimes hurt it
• Gallery dealers preferred a clean COA card and a hosted URL over a chain-anchored token
• The print itself, the pencil signature, and the COA card remained the canonical artifacts

For a longer analysis of why blockchain-based provenance lost to federated registries in the regulatory space, see DPP vs blockchain provenance for fashion, craft and luxury brands.

Does the EU Digital Product Passport apply to art prints?

Not in the first wave. ESPR (the EU regulation behind DPP) targets product categories with high environmental impact first: batteries, textiles, electronics, construction products, furniture. Art prints are a niche category and unlikely to be on the mandatory list until much later, if at all.

For artists selling prints, this means the EU DPP is not a regulatory issue today. But a structured digital COA that includes manufacturer (the artist or studio), origin (where the print was made), material composition (paper, ink), and conformity statements is already 80% of the DPP format. An artist who adopts this format today is forward-compatible for any future regulation without rebuilding.

How does Editioned handle the art print case?

Editioned ships the full numbered-edition workflow for prints: edition badges on product pages, scarcity bars, auto-assign on order so the buyer sees their specific edition number at checkout, hosted certificate per edition with QR code, auto-revoke on refund. The certificate page is hosted on the artist's own Shopify domain, so the URL stays under the artist's control for the life of the store.

The certificate fields include all the standard art-print data points: title, edition number, medium, paper, dimensions, year, studio location, and a signed statement. The hosted page can show a high-resolution image of the print, a maker's statement, and any chain of custody if needed. Pro tier exports the same data as an EU Digital Product Passport record for forward compatibility.

Flat monthly pricing (Free, $49/mo Pro, $99/mo Studio) with no per-certificate fees. The marginal cost of issuing a certificate is zero, which matters when you are selling editions of 75, 100, or 250 prints at print-tier prices. 30-day Pro trial on every install with no card required.
