Ultracode with the legacy revision 1 format
Some older Ultracode decoders were built against the original revision 1 specification -- this generator selects that legacy format by default instead of the current revision 2.
Same generator, one preset applied
This experience uses the same Ultracode capability as the primary generator, with the legacy format selected ("rev": 1) instead of the current revision 2.
Example data
The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.
Workflow
Enter your data, confirm the preview, then export SVG or PNG for the label artwork.
Job-specific settings
No job-specific options beyond the legacy revision selection are applied here.
Scanning notes
A reader built only against the current revision 2 specification may not decode a revision 1 symbol correctly -- confirm which revision your decoder expects before relying on this preset.
Common mistakes
Requesting error correction level "EC0" without this preset's own legacy revision would normally be rejected -- this preset's revision selection is what makes that level valid, though the committed example itself does not use EC0.
Standard
Ultracode is a color-capable 2D matrix symbology with two defined format revisions.
