The CMYK color model is based on the CMY color model, which omits the black ink. Four-color printing uses black ink in addition to subtractive primaries for several reasons: [ 2 ] In traditional preparation of color separations, a red keyline on the black line art marked the outline of solid or tint color areas.
Rich black, in printing, is an ink mixture of solid black over one or more of the other CMYK colors, [1] resulting in a darker tone than black ink alone generates in a printing process. [ 2 ] [ 3 ] Rich black
The widespread offset-printing process is composed of the four spot colors cyan, magenta, yellow, and key commonly referred to as CMYK. More advanced processes involve the use of six spot colors ( hexachromatic process ), which add orange and green to the process (termed CMYKOG ).
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.
In printing, registration black is a black color that includes 100% of each of the process colors used. Typically these are cyan, magenta, yellow and black , [4] but if different colors are used, registration black marks are made with all of the colorants (inks). [4] Registration black is used for printing crop marks and registration marks ...
Colors can be created in printing with color spaces based on the CMYK color model, using the subtractive primary colors of pigment (cyan, magenta, yellow, and black). To create a three-dimensional representation of a given color space, we can assign the amount of magenta color to the representation's X axis , the amount of cyan to its Y axis ...

CcMmYK, sometimes referred to as CMYKLcLm or CMYKcm, is a six-color printing process used in some inkjet printers optimized for photo printing. [1] It complements the more common four-color CMYK process, which uses only cyan, magenta, yellow and black, by adding light cyan and light magenta.
