Print preflight
A QR code can scan in the generator and still fail in the finished design. It may be reduced, cropped, recoloured or placed too close to other artwork.
Before approving a print run, check the exported file, the complete layout and a physical proof. Test each one at the size, distance and lighting people will use.
Key decisions
Scan the finished layout
Scan the exported PDF or image as well as the source code. Layout software can resize, crop or rasterise the pattern.
Keep clear space around it
Leave the required blank margin on every side. Borders, photos, folds and nearby text can make the code harder to detect.
Use a suitable print file
Use SVG, PDF or EPS when your layout or printer accepts vector files. Otherwise use a high-resolution PNG.
QR print preflight decisions
| Check | Pass condition | Failure to avoid |
|---|---|---|
| Final size | Large enough to scan from the expected distance | A small code on a poster, package or glossy label |
| Quiet zone | Blank space on every side | Borders, stickers or cut lines touching the pattern |
| Contrast | Dark pattern on a light, plain background | Faint colours, transparency, shadows or a busy photo |
| Logo and styling | Small centred logo and high error correction | Large logo or effects that hide too many squares |
| Export format | SVG, PDF or EPS for artwork that will be resized | A screenshot or a small image enlarged for print |
- Check the destination, payment details, contact information or phone action before exporting.
- For close-up scans, start at 2 cm (0.8 in) and make the code larger for posters, windows and signs.
- Leave a clear four-module margin on every side of the code.
- Use a dark pattern on a light background, with enough contrast to distinguish every square.
- Avoid shadows, transparency, filters and busy images behind the pattern.
- Keep the code away from folds, trim lines, curved edges and reflective glare.
- Scan the exported artwork from the distance people will use it, with more than one phone if possible.
- Print a full-size proof before ordering a large run.
- Save the master QR file and destination details with the final artwork.
Check the file, layout and proof
- 1
Generate the final asset
Generate the code with the final destination or data, colours, logo, error-correction setting and file format.
- 2
Place it in artwork
Keep the clear margin, set the intended size and avoid effects that blur, cover or distort the pattern.
- 3
Scan the proof
Scan the exported file and a printed proof from the angles, distance and lighting people will encounter.
Frequently asked questions
Should I test the source QR code or the final artwork?
Test both, but approve the exported layout and a printed proof. The source may scan well before it is resized, cropped, recoloured or compressed in the design.
What size should a printed QR code be?
For close-up scans, 2 cm (about 0.8 in) is a useful starting point. Make it larger for longer distances, denser patterns, low light or window displays.
Which QR code format is safest for print?
SVG, PDF and EPS stay sharp when resized, so they are good choices for print. If you use PNG, export it at the final size and resolution rather than enlarging it later.
Can I recolor a QR code in design software?
Yes. Keep strong contrast, avoid transparency or gradients across the pattern, then scan the exported design.
Do I need a physical proof before printing?
For an important print run, test a physical proof. Paper, ink, lamination, light and viewing distance can expose problems a screen preview misses.
