Scan Reliability
Use the Designer’s built-in reliability feedback to identify risky styling choices before you print.
How to use Scan Reliability
The preview includes a collapsible Scan Reliability panel. The score is recalculated as the design changes and can provide warnings or recommendations.
Common causes of lower reliability
- Low foreground/background contrast
- Large center logos or logo backgrounds
- Reduced quiet zone
- Aggressive artistic integration
- Very small or unusual data modules
- Decorative finder-eye treatments
- Strong overlays
Tip: Treat the reliability indicator as a design assistant, not a substitute for real-device testing.
