Start with a reference list
Download the print review sheet (A4 PDF).
For each item, record an identifier, expected content, filename and layout position. Add the language, caption and document version. Build this list from the approved request, not solely from the images you are about to check.
Fictional example: A01 is product A on page 2; A02 is product B on page 3. If both images lead to product A, a QR reader can find both readable. Only comparison with the reference list reveals the error.
Check every distinct payload
- Decode every distinct QR code from the final layout file.
- Compare the exact result with the reference: domain, path and parameters.
- Check the associated caption and position.
- Open expected links and verify the right document for the intended audience.
- Record the result and resolve differences before approval.
If an image is repeated, also check that no instance has been replaced or distorted in the layout. A visual sample does not establish that every destination in a variable series is correct.
Validate geometry and finish
Measure the QR code including its margin on an actual-size proof. Check that no cut, fold, hole or text interferes with the usable area. Inspect the most demanding examples: small format, dense grid, curved material or glossy finish.
Test with devices and conditions representative of your distribution. Record those conditions without treating a few successful readings as a universal guarantee. Keep digital content validation and physical material validation as separate results in your record.
Freeze what was actually approved
Your approval can contain six items: series reference, final PDF version, destination register, dimensions and finish, check results, and approver name and date. Keep them together with the files sent to the printer.
After any change to a QR code, image, link or layout, reassess the affected checks. Prepare data with the CSV register. Retain control after distribution with company access management.
