This is a Fargo HDP5600 YMCK ribbon, part number 084511 only. The Fargo HDP5600 is a reverse transfer ribbon which requires a separate retransfer film, Fargo 084500, to print on the cards.
This color ribbon will print 500 cards on one side, 250 cards with color on front and black only on the back or 250 cards with color on both sides. This is a YMCK ribbon, which means it has a Yellow panel, Magenta panel, Cyan panel, Resin Black panel and then starts again with the Yellow panel. This ribbon uses a resin black panel to print black where needed. This is the most effective for barcodes, or if the customer wants the black to stand out. A YMCK ribbon will still only print 250 two-sided cards, even if only black is printed on the back side of the card.
This ribbon is for a retransfer printer, which initially prints the image onto a film ribbon, then transfers the film onto the card. For this reason, there is no overlay panel on the dye film ribbon because the transfer film acts as an overlay panel.
