5 Costly QR Code Marketing Mistakes to Avoid

A printed marketing mistake is permanent. Avoid these common QR design errors before you send files to print.

The Pain Point & Challenges

Printing thousands of packages or brochures only to find the QR code won't scan due to size, placement, or bad contrast ratios.

Qodex provides design validation, scannability contrast alerts, and dynamic target editing to protect your campaign budgets.

•Never print a QR code smaller than 0.8 x 0.8 inches (2 x 2 cm) for standard brochures.
•Leave a clear margin (quiet zone) around the QR code to help camera lenses scan it.
•Always print a test copy and scan it under varied light before running the full batch.

Shiny laminate can reflect overhead light, making scanning difficult. Use matte paper for reliable scanning.

Simply open your Qodex dashboard, edit the destination, and save. The printed code is instantly corrected.
