Prepare a QR code for print: the practical checklist
A successful preview on screen does not guarantee reliable scanning on a glossy, curved or small surface. Test the final artwork in real conditions before the full print run.
QUICK OVERVIEW
What this changes in practice
Physical size
Scanning distance determines the minimum useful size.
Contrast
Dark modules on a calm, light background.
Final test
Several phones, angles and lighting conditions.
01
Size and scanning distance
As a starting point, make the QR width roughly one tenth of the intended scan distance: about 3 cm for a 30 cm scan. This is a practical rule, not a guaranteed limit; dense matrices and difficult materials need more space.
- Do not resize after final testing
- Account for data density
- Test the actual artwork
02
Contrast and quiet zone
Keep at least four modules of clear space around the code. Dark modules on a light background remain the most reliable. Avoid photography, transparency and decorative frames inside the quiet zone.
- No border inside the quiet zone
- No inverted colours without testing
- Never cover finder patterns
03
File format and material
Use SVG or PDF for print so module edges stay sharp. Test reflections on gloss and foil, distortion on curved packaging and ink spread on fabric.
04
Final test before production
Print one sample at final size. Scan it on iOS and Android from realistic angles and lighting, then verify the HTTPS destination and page speed.
- At least two different devices
- Real material and lighting
- A working public destination
FAQ
Frequently asked questions
How big does the code have to be?
Start at roughly one tenth of the distance it will be scanned from — about 3 cm for 30 cm — and then test the real artwork. Dense data and difficult materials need more, so the rule is a floor rather than a target.
Can a logo sit in the middle of the code?
Usually yes: error correction reconstructs the modules a modest centre mark covers. Never cover the three finder squares in the corners, and scan a printed sample rather than trusting the preview on screen.
Which export formats does Mosaqo support?
Mosaqo exports PNG for digital placements and SVG or PDF for scalable, print-ready artwork.
Can I change a QR code destination after printing?
Yes, when the QR code uses dynamic mode. The printed matrix points to a Mosaqo short address, while the final destination can be updated in your workspace.
