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.
(The secondary colors of pigment are blue, green, and red.) As such, the CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips. Process magenta is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB.
