The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: cyan, magenta, yellow, and key (most often black).
Color space conversion is the translation of the representation of a color from one basis to another. This typically occurs in the context of converting an image that is represented in one color space to another color space, the goal being to make the translated image look as similar as possible to the original.
CMYK is used in the printing process, because it describes what kinds of inks are needed to be applied so the light reflected from the substrate and through the inks produces a given color. One starts with a white substrate (canvas, page, etc.), and uses ink to subtract color from white to create an image.
To see how this works in practice, suppose we have a particular RGB and CMYK color space, and want to convert from this RGB to that CMYK. The first step is to obtain the two ICC profiles concerned. To perform the conversion, each RGB triplet is first converted to the Profile connection space (PCS) using the RGB profile.
If you wish to obtain CMYK values for these colors, you will get appropriate conversion values from your graphics application when you define the type of ink and paper you will be printing on. A CMYK value is meaningful only if you can specify what ink–paper–process standard it is supposed to be used with.
The CMYK coordinates describe the amounts of each of cyan, magenta, yellow and key pigments (such as inks) which are mixed subtractively in order to create a particular color. In Wikipedia, the coordinates are presented as four numbers separated by commas, as in this example for the color orange:
