ZXP Series 8 Ribbon I Series YMCKKI Ribbon, 415 Images/roll. This ribbons consist of yellow (Y), magenta (M), cyan (C), and black (K) panels for printing full color and black on the front. The second black (K) resin and inhibitor (I) panel can be used on the front or back. The inhibitor panel prevents the retransfer film from adhering to signature panels or surface foils (front of card). Retransfer film covering signature panels would make it difficult to write on. This ribbon is compatible with the ZXP Series 8 and ZXP Series 9 Printer.
