Color theory
There are two methods used to create color. The (which is used in this printer) and the additive procin monitors and television).
Subtractive color theory

Half-toning
Half-toning (also called dithering) is a method usepigment to create a full spectrum of color. Becausdots of toner on a page to create an image rather mixing the color (like paint), the dots are distributepatterns. Although they are not physically combineye integrates the dots and the viewer perceives tcolor.
Process colors
The printer does not use half-toning for every appfour basic colors (cyan, magenta, yellow, or black)a solid color. Since red, green, and blue are formebase colors, they are called process colors. See pexplanation of how the process colors are createddrum.
