Codablock F for wider, fewer-row labels

Labels with more horizontal space available but limited vertical space use this generator with a wider column layout applied, needing fewer stacked rows for the same data.

Same generator, one preset applied

This experience uses the same Codablock F capability as the primary generator, with a fixed 20-column layout ("columns": 20) preset.

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 fits your label's row budget, then export SVG for the label artwork.

Job-specific settings

Adjust rowheight/sepheight further if your label stock needs taller or shorter rows.

Scanning notes

Codablock F requires a scanner or imager capable of reading a stacked/multi-row symbology, not a simple single-pass linear scanner.

Common mistakes

Choosing a column count that leaves too little row budget for the data length is the most common failure.

Reference

Codablock F is documented in the bwip-js/BWIPP symbology reference.
