What Do YMCKO and YMCKOK Mean?

Members of the print industry easily recognize the letters “CMYK” as the four basic colors of printing: Cyan, Magenta, Yellow, and Black. The four of these colors are layered in different increments on paper to create hundreds of color output combinations.

This same method applies to ID card printing. The letters “YMCK” also stand for the same four basic printing colors: Yellow, Magenta, Cyan and Black. When a color cartridge is indicated as “YMCKO,” the cartridge first prints all four basic colors then adds a clear Overlay (the “O”) at the end to protect the printed image.

A cartridge marked as “YMCKOK” is also a color cartridge complete with clear Overlay, but the “K” at the end indicates this cartridge is used for dual-sided card printing. This cartridge allows you to print full color on the front side and just Black on the reverse side.

Other Abbreviations

Some Black cartridges bear different abbreviations like KdO and KrO. The “K” indicates it is a Black cartridge and the “O” at the end indicates it also comes with a a clear Overlay. The lowercase “d” stands for “dye” while the “r” stands for “resin.” The KdO cartridge is ideal for printing grayscale images with light, midtone, and shadow while the KrO is perfect for printing crisp black lines in logos and barcodes for easy reading.
