Kodak Makes Invisible Barcodes

Kodak recently introduced a new ink that’s virtually invisible. The ink, which Kodak has coined Kodak Nexpress is a red fluorescing dry ink that is clear to the naked eye, but becomes illuminated when using the appropriate UV light source.

The ink will be used to print non-reproducible barcodes on printed materials, and they will only be able to be read with specialized barcode readers, making it ideal for security and inventory management applications such as certified documents, medical prescription pads, drivers’ licenses and event tickets. The ink allows clear barcodes to be printed inline and can even handle variable data printing, allowing each item to be marked with unique information.
