The RGB color model creates colors by mixing light, red, green and blue. All video displays are RGB. Since it is impossible to print a light mixture printers are able to simulate full color by using four colors, cyan, magenta, yellow and black. Most new color laser copy machines automatically convert RGB to CMYK when a digital file is sent, but the results may be off color.
