QR distribution / print verification
Verify QR print size, quiet zone and decoded content
Before distribution, compare the printed size, clear margin and content that was actually decoded. Do not PASS while any condition is unknown.
Separate three result states
A visible QR image is not the same as a scannable distributed item. Record size, quiet zone and decoded content separately.
| State | Meaning | Decision | Next step |
|---|---|---|---|
| Verified | All three conditions match | Compare the sheet | Keep the final sample |
| Mismatch | Size, margin or content differs | Do not distribute | Generate or print again |
| Unknown | Unreadable or not inspected | Do not PASS | Inspect the real item |
Use synthetic fixtures for the three conditions
qr-sample.svg is the 30 mm, 4 mm quiet-zone, expected-URL baseline. qr-small.svg is too small and qr-wrong-content.svg has a content or margin mismatch. No real scan result is included.
Follow this order
- Fix the QR URL and its destination record.
- Record the final print size and required quiet zone.
- Scan the final-size physical sample and compare decoded content.
- Treat a small size, narrow margin or wrong content as mismatch.
- If unknown remains, stop distribution and record it on the sheet.
This guide and its fixtures are static files. No real QR or input is sent or stored externally.
What this does not guarantee
Verified means that the declared three conditions match. It does not guarantee every device, lighting condition, printer or destination will scan successfully.
