CMYK - 3D Subtractive Model

In the CMYK model:

image\sqrblit.gif C stands for Cyan.

image\sqrblit.gif M stands for Magenta.

image\sqrblit.gif Y stands for Yellow.

image\sqrblit.gif K stands for Black.

Printing processes typically use Cyan, Magenta, Yellow, and Black ink on white paper to reproduce colors. Unlike RGB color, which is �additive� because light is added by the amount of color in each of the components, CMYK is �subtractive� because light is subtracted from the bright white background whenever color is applied. This means that higher values for component colors create darker overall colors.

In theory, 100% of each of Cyan, Magenta, and Yellow should produce black, but in reality a pure black is not usually obtained. This is compensated for by introducing the K (black) component.

CMYK, like RGB, is a device dependent color model.
