Evolis YMCKO ribbon prints a full spectrum of colors by combining yellow magenta and cyan panels and using varying degrees of heat. The K panel is a black resin panel typically used for printing text and bar codes and the O panel is a thin clear protective overlay that is applied over the entire surface of your cards. Evolis Ribbon is specially back-coated to extend printhead life. It generates approximately 200 full color prints in your Zenius Primacy and replaces the discontinued Evolis R5F001AAA ribbon.
