Codabar generator
Classic code in blood banks, libraries and air cargo — easy to print even on dot-matrix printers.
Screen settings
Colors apply to every export. The scan check re-decodes the recolored code, so a low-contrast combination fails honestly — dark bars on a light background scan best.
PNG/JPG export in high resolution, SVG for websites — and the PDF is true vector in RGB: sharp at any size, right for documents and office printers.
About Codabar
Codabar is one of the oldest barcodes and survives where its self-checking, technology-forgiving design once made it ideal: blood bags, library books and waybills. New systems should choose Code 128, but millions of Codabar labels are still scanned daily.
Used for
- Blood banks (ISBT legacy)
- Libraries
- Air cargo and couriers
