Zebra ZC Series YMCKOK 6-Panel Color Ribbon, 200 Images/Ribbon. For use with Zebra ZC300 ID Card Printers.
A Zebra YMCKOK ribbon is the same as a YMCKO ribbon but with an additional “K” black panel for printing on the back side of a card.
The first 5 panels (YMCKO) are for the front side of a card (Y=Yellow, M=Magenta, C=Cyan, K=Black, O=Overlay) and provide for full-color printing with an overlay panel while the last "K" black panel is used for monochrome printing on the back side of a card. The Overlay panel provides a thin layer of clear protection to your cards which helps protect the card from fading and normal wear and tear.
This ribbon is used for dual-sided card printing.
