Printing QR Codes: Format, Margin, and Checklist
Good printing results depend on a sufficient margin, clear contrast, and a suitable output format. SVG stays sharp at any size, while PNG works well for digital or fixed-size output.
PNG or SVG?
PNG is a raster image with a fixed pixel count. It fits well into digital documents, but should be exported at sufficient resolution for print.
SVG describes the modules as vectors and stays sharp when scaled. For layout and print software it's often the more robust choice.
Quiet Zone and Contrast
An empty, light-colored zone must remain around the pattern. It helps the camera separate the actual symbol from the background.
Dark modules on a light background are a reliable starting point. Decoration, text, or images should never reach into the quiet zone.
Paper, Screen, and Surface
Glossy, curved, or heavily textured surfaces can create reflections and distortion. On screens, the code shouldn't become unreadable due to glare or automatic brightness adjustments.
The required edge length depends on scan distance, data amount, and error correction; there's no universal minimum size.
Print Checklist
Before a larger print run, test the actual printout under the intended conditions.
- Destination address or payload verified
- Margin clear all around
- Sufficient contrast between modules and background
- Output size and scan distance tested in practice
- Logo not oversized
- PNG resolution or SVG file checked
