The Ultimate Guide to Printing QR Codes
The Ultimate Guide to Printing QR Codes
Printing QR codes seems simple, but there are common mistakes that can render your codes unscannable. This guide covers everything you need to know to get it right.
Before You Print: The Golden Rule
Set your QR code's short link before printing. With dynamic QR codes, you can always change the destination URL β but the short link (the URL encoded in the QR pattern) is permanent. Changing it after printing means your printed codes break.
File Format and Resolution
Use PNG at High Resolution
Export your QR code at the highest resolution available. For print materials:
Avoid JPEG
JPEG compression adds artifacts around the sharp edges of QR code modules, which can interfere with scanning.
Sizing Guidelines
| Material | Minimum QR Size | Recommended |
|---|---|---|
| Business card | 2cm Γ 2cm | 2.5cm Γ 2.5cm |
| Flyer (A5/A4) | 3cm Γ 3cm | 4cm Γ 4cm |
| Poster | 5cm Γ 5cm | 8cm Γ 8cm |
| Banner/billboard | 15cm Γ 15cm | Scale for distance |
Scanning distance formula: Maximum scan distance β 10Γ the QR code width.
Material Considerations
Paper and Card Stock
Standard paper works perfectly. Glossy finishes can cause glare under certain lighting β matte or semi-gloss is safer.
Packaging
Ensure the QR code isn't placed on a curved surface where it wraps too much. The flatter the surface, the better the scan reliability.
Clothing and Fabric
QR codes on t-shirts or bags work, but the code needs to be larger than usual and the fabric should be smooth when worn.
Metal and Plastic
Reflective surfaces can interfere with scanning. Use a matte finish or anti-glare coating over the QR code area.
Color and Contrast
Common Printing Mistakes
Conclusion
Printing QR codes is straightforward when you follow these guidelines. Export at high resolution, size appropriately, maintain contrast, and always test before your final print run. With ForeverScan QR's dynamic codes, you get the peace of mind that your destination can change β even after printing.
