Executive Summary
Printing QR codes requires setting correct sizing and margins to prevent camera failures. This guide sets out rules for print production.
1. Sizing and Distance Ratios
Ensure a minimum size of 2 x 2 cm for URL codes. For long distances, apply a 10:1 ratio: a poster scanned from 10 feet needs a 1-foot code.
2. Quiet Zones & Margins
Leave a solid margin equal to 4 code modules around the matrix to prevent adjacent text or graphics from interfering with decoders.
Frequently Asked Questions
What format should I use for printing?
Always use vector formats like SVG or PDF to keep the matrix edges sharp at any print scale.
