UPC-E Composite for taller linear bars
Small retail item labels printed on lower-resolution thermal printers benefit from a taller linear-component bar height -- this generator applies a fixed, taller height by default.
Same generator, one preset applied
This experience uses the same UPC-E Composite capability as the primary generator, with a fixed 20mm bar height ("height": 20) for the linear component.
Example data
The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.
Workflow
Enter your linear and composite data separated by a pipe character, confirm the preview, then export SVG or PNG for the label artwork.
Job-specific settings
No job-specific options beyond the fixed 20mm bar height are applied here.
Scanning notes
UPC-E Composite requires a reader capable of decoding both a UPC-E linear symbol and a linked 2D composite component in a single scan.
Common mistakes
An incorrect UPC-E check digit or a missing pipe separator are the most common rejections; both are unaffected by the height preset itself.
Standard
UPC-E Composite is defined in the GS1 General Specifications' Composite Symbology rules.
