Low Error Correction for Printed QRs
Use Level Q (25%) or Level H (30%) if you intend to print stickers or banners that may suffer physical scuffs or wrinkles.
Inverted Low Contrast Colors
QR scanners expect dark modules on a light background. Low contrast (e.g. light gray on white) reduces scan reliability.
Recommended remediation
Test your generated QR code with both iOS Camera and Android Lens before high-volume print runs.
