The scan check
After every change the designer decodes the exact image it drew and compares it with what you entered.
- Scans correctly means the decoded text matched.
- Does not scan means it did not. Reduce the logo, raise the contrast or use square modules.
Even when it scans, it warns you when:
- contrast between code and background is below 4 to 1, measured on the lighter end of a gradient;
- the logo covers more than 15% of the code;
- the code is lighter than its background, which many scanners refuse;
- the background is transparent, since it takes the colour of whatever it is printed on.
The check is a clean digital image. Print a copy and scan it with a phone before printing many.

- PNG includes everything, logo and text.
- SVG is rebuilt from your settings so it stays sharp at any size. A logo is not included in the SVG, because a logo is a picture rather than a shape.
