UPC-A Composite with guard-whitespace indicators
Retail POS scanner-alignment conventions that expect quiet-zone guard-whitespace indicator marks alongside the UPC-A guard bars use this generator with those marks turned on.
Same generator, one preset applied
This experience uses the same UPC-A Composite capability as the primary generator, with quiet-zone guard-whitespace indicator marks turned on ("guardwhitespace": true) instead of the primary's default.
Example data
The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.
Workflow
Enter your pipe-delimited UPC-A and GS1 composite data, confirm the preview, then export SVG for the retail-shelf artwork.
Job-specific settings
No job-specific options beyond the added guard-whitespace indicator marks are applied here.
Scanning notes
UPC-A Composite requires a reader capable of decoding the linked GS1 Composite Component in addition to the UPC-A linear symbol; a reader that only decodes UPC-A still reads the linear half correctly.
Common mistakes
A missing pipe character or an incorrect UPC-A check digit are the most common rejections.
Standard
UPC-A Composite pairs GS1's own UPC-A standard with GS1's own Composite Component standard.
