About color separations. To reproduce color and continuous-tone images, printers usually separate artwork into four plates (called process colors)âone plate for each of the cyan, magenta, yellow, and black portions of the image.
In inkjet printing, the proper use of black is still fundamentally important for getting good color reproduction. TechTarget also says: CMYK is a scheme for combining primary pigments. The C stands for cyan (aqua), M stands for magenta (pink), Y is yellow, and K stands for black. The CMYK pigment model works like an upside-down version of the RGB (red, green, and blue) color model. Many paint and draw programs can make use of either the RGB or the CMYK model. The RGB scheme is used mainly for computer displays, while the CMYK model is used for printed color illustrations (hard copy).
