Frequently Asked Questions

What contrast ratio is safer for QR codes?

Higher is better. Aim for strong contrast, preferably a dark foreground on a light background.

Can a colorful QR code still scan?

Yes, if contrast remains strong, the quiet zone is clear, and the foreground is darker than the background.

Does contrast guarantee scanning?

No. Contrast helps, but scan reliability also depends on size, quiet zone, print material, lighting, and QR complexity.
