QR Code Error Correction Explained

QR codes include redundant information that helps scanners recover data even when part of the pattern is covered or damaged.

Higher error correction gives more resilience, but can make the QR pattern denser.

A logo covers part of the QR pattern. High error correction helps compensate, which is why FluidQR uses a logo-friendly setup.

Even with error correction, large logos, weak contrast, and tiny print sizes can still cause scan issues.

Keep the logo centered, leave margin around the code, preserve contrast, and test the final artwork.

For mission-critical print materials, use a simpler design and larger QR size.
