Color Printing Basics

Additive (Emitted) and Subtractive (Reflected) Color Models
All light is a mixture of red, green, and blue, which is normally called the RGB
model. When red, green, and blue are of equal intensities, the RGB color model
produces white.
Note
RGB is also called additive or emitted color. The colors on your computer
screen are produced by varying the intensities of RGB.
Printed color is a mixture of cyan, magenta, and yellow, which is normally called
the CMY color model. When mixed in equal proportions the CMY color model
produces black.
Note
CMY is also called subtractive or reflective color. Your printer uses CMY toner
plus K (black) toner (CMYK color model) to provide full color printing.
