Abstract

Methods and systems are disclosed for printing vibrant grey color(s) on plastic cards. The following features, which can be used individually or in any combination thereof, can be implemented to achieve the vibrant grey color(s): 1) use of CMYK pigment inks to achieve CMYK printing; 2) a pixel extraction process and/or a print trapping process; 3) two separate print commands including a CMY (or CMYK)+blending print command and a K+blending print command; and 4) proper card set-up.
