Fargo 6-Panel YMCKOK Ribbon Cartridge with Cleaning Roller Full-Color Ribbon with Two Resin Black Panels and Clear Overlay Panel (200 Images/Roll). For use with Fargo DTC400 and DTC400e ID Card Printers.
A Fargo 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.
