The Evolis R2131 Monochrome Ribbon is compatible with the Evolis the Evolis Quantum 2 ID Card Printer. This all black resin (K) ribbon is great for printing all black text, barcodes, pre-printing cards, etc. One of the main benefits of printing with a monochrome ribbon is the speed. It also is efficient as rather than using a full panel to print per card, it only uses the amount of ribbon when the surface is actually being printed.
