Barcodes
Barcodes need correct size, quiet zones, contrast and a flat placement to scan.
See it
- No quiet zone around the bars
- Placed across a fold on a busy background
Why it matters
EAN-13 at 100% is about 31.35 x 22.85 mm including quiet zones. GS1 guidance allows roughly 80% to 200% magnification; check your retailer's rules.
Scanners need clear quiet zones, strong contrast (dark bars on light ground) and a flat surface. Never put barcodes over folds or patterns.
How to apply it
- Keep EAN-13 within the allowed magnification range
- Leave clear quiet zones on both sides
- Use dark bars on a light background
Common mistakes
- Truncating height without checking
- Placing over folds or patterns
