The Brady R1000 series ribbons are based on a resin formulation that offers a high performance image with strong solvent and scratch resistance. Tough, smear-proof ribbon produces long-lasting printed text that can withstand years in industrial areas and outdoor conditions. B30 Series "Drop & Click" print ribbons enable 5-second ribbon supply changes. No calibrating, no threading, no waste, no hassles and the ink always faces the right direction. Self-contained B30 Series cartridges drop straight into the printer with a "click".
