Channel Code with a narrower finder pattern

Compact numeric identification on tightly constrained label stock uses this generator with a shorter finder pattern applied.

Same generator, one preset applied

This experience uses the same Channel Code capability as the primary generator, with a 5-bar finder pattern ("shortfinder": true) instead of the default 9-bar pattern.

Example data

The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.

Workflow

Enter your 2-to-7-digit value, confirm the preview at the narrower finder pattern, then export SVG for the label artwork.

Job-specific settings

No job-specific options beyond the fixed finder-pattern width are applied here.

Scanning notes

Channel Code requires a reader capable of decoding its own combinatorial bar-pattern structure.

Common mistakes

A value too big for its own digit count's maximum channel value is the most common rejection.

Reference

Channel Code is documented in the bwip-js/BWIPP symbology reference.

For a general-purpose linear symbol without Channel Code's fixed maximum-value-per-digit-count constraint, use the Code 128 generator instead.
