Your retail team needs a new headline on an accessory campaign. The factory image stays, one distributor’s approved offer stays, and a year-round asset should remain offer-free. A fast batch edit can still cost more than a manual pass if every apparent shortcut adds another proofing round.
Read the speed claim at the right level
Canva’s newsroom lists Introducing Canva Brush on October 29, 2026. Canva says Brush powers supported design edits in Canva AI for Pro subscribers and describes changes from single lines to multi-slide designs. The company’s speed and per-edit cost comparisons are against its own previous design agent. Those comparisons do not measure the brand team’s time to prepare the brief, verify retail copy or approve an export.
Give your supplier three nearly identical proofs
ONCE’s exception test uses a duplicate of the signed-off artwork, not a live campaign. Suppose a brand sourcing rechargeable desk lamps in China wants to change its holiday display headline. Choose three pages and write one instruction per page, with a list of protected elements.
- Change one: Replace the headline on the participating retailer’s proof. Inspect the final crop for lost words, shifted line breaks or interference with the product.
- Keep one: Preserve the distributor’s different approved line, even if it shares a phrase with the old headline. Verify the product model and compatibility language against the original.
- Leave one blank: The year-round sheet never had a holiday offer. Check that no label appeared and that the original imagery and mandatory copy survived.
Ask for the approved source, change list and exported proofs together. A change may look acceptable in the editor and still fail on a narrow placement. A supplier can reuse the same campaign idea across formats while treating the permission to change each element as a separate instruction.
Measure approved exports, not fast previews
Run the same small brief through the manual route and the proposed AI route. Count preparation, editing, review, correction and export checks. Apply your actual labour rates, add the tool cost allocated to the batch and divide by the number of approved assets delivered on time. Record rejected or late assets separately; a route that delivers zero approved files has no useful unit cost. If exceptions consume the savings, split the work by retailer or use a locked template. Scale the AI route only after it can leave protected artwork alone and the full cost of approval is lower.
