Print Is Where QR Codes Shine
QR codes were invented for print. They bridge the physical world with digital experiences in a way no other technology can match. But printing QR codes requires careful attention to size, resolution, material, and placement. A code that works perfectly on screen can fail completely in print if these guidelines are not followed.
File Format Selection
SVG (Recommended): Vector format that scales to any size without quality loss. Ideal for professional print production. Works with Adobe Illustrator, InDesign, and most print vendor workflows.
PDF: Vector-based when exported correctly. Best for sending to print vendors who want press-ready files. Ensures color accuracy across different RIP software.
PNG: Raster format. Acceptable for digital printing and large-format output. Export at minimum 300 DPI at the intended print size. A 3cm code needs to be at least 354x354 pixels.
Never use JPEG: JPEG compression creates artifacts around the sharp edges of QR modules, degrading scannability.
Size Guidelines by Application
Business cards: Minimum 2cm x 2cm. Position on the back with full quiet zone.
Product packaging: Minimum 2.5cm x 2.5cm. Account for the curvature on bottles and cans.
Brochures and flyers: Minimum 3cm x 3cm. Place near the call-to-action text.
Posters (indoor): Minimum 5cm x 5cm for viewing at 1-2 meters.
Banners and signage: Scale to 1/10th of expected viewing distance.
Material Considerations
Paper stock: Matte or uncoated paper provides the best scan reliability. Glossy paper can create glare under certain lighting. If using glossy stock, consider a spot matte varnish over the QR code area.
Corrugated cardboard: The surface texture can distort fine details. Use larger module sizes (lower version codes) and higher error correction.
Metal and glass: Reflective surfaces require careful placement to avoid glare. Test under the actual lighting conditions where the product will be displayed.
Fabric: Woven materials can distort code modules. Use significantly larger codes (minimum 5cm) and highest error correction level.
Color and Contrast in Print
Print colors behave differently than screen colors. When specifying QR code colors in CMYK, use 100K (pure black) for maximum contrast. Avoid rich black (C40 M40 Y40 K100) as it can cause registration issues on small modules. For brand colors, convert your Pantone or RGB brand color to CMYK and verify contrast ratio against the background in the actual print profile.
Pre-Press Checklist
- Code is in vector format (SVG or PDF) or raster at 300+ DPI
- Quiet zone is at least 4 modules wide on all sides
- Foreground-to-background contrast ratio exceeds 4:1
- Test print has been scanned on 3+ devices
- Code links to the correct destination URL
- Analytics tracking is active and receiving test scans
- Error correction level matches code complexity (H for logos, M for clean)
