The Matica ChromXpert Diamond Line KO Ribbon is a black-and-overlay ribbon designed specifically for the Matica MC310 card printer, delivering 600 prints per roll. The KO configuration — black panel combined with a protective overlay — produces sharp monochrome output across text, barcodes, and images, while the overlay adds a layer of durability that extends the working life of each printed card.

ChromXpert ribbons are engineered to work within Matica's ecosystem rather than alongside it. The MC310 supports automatic ribbon identification, so the printer recognises the ribbon on loading and monitors consumption as you go — no manual tracking, no guesswork about when you're running low. The kind of quiet reliability that matters most when you're running a busy print operation and have other things to think about.

Manufacturer part number PR20319304. If you're printing monochrome cards on a Matica MC310 and want consistent results without the overhead of managing consumables manually, this is the ribbon to specify.
