ZXP Series 8 Ribbon I Series YMCKI Ribbon, 500 Images/roll. This ribbons consist of yellow (Y), magenta (M) and cyan (C) panels for printing full color on the front. The 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.
