Pros
- GS1 DataBar Expanded Stacked scans on every retail checkout imager worldwide.
- Check digits are computed or verified before anything prints.
- SVG export stays sharp on packaging artwork at any size.
- Quiet-zone guidance is built into the preview and print SVG.
Cons
- GS1 DataBar Expanded Stacked needs precise widths — shrinking below ~80% magnification hurts scans.
- Curved cans and shrink-wrap glare distort the outer bars.
- Cropping the quiet zones is the most common print failure.
- Styling beyond black-on-white is not safe for checkout.
Form requirements
- Enter (01)09501101530001(21)12345.
