What is the difference between CMYK and RGB color for graphics?
Short for Cyan-Magenta-Yellow-Black, and pronounced as separate letters, CMYK is a color model in which all colors are described as a mixture of these four process colors. CMYK is the standard color model used in offset printing for full-color documents such as book covers, since iUniverse, Inc. does not print color images in our books. Because such printing uses inks of these four basic colors, it is often called four-color printing. In contrast, display devices (PDAs, monitors, etc.) generally use a different color model called RGB, which stands for Red-Green-Blue. One of the most difficult aspects of desktop publishing in color is color matching(properly converting the RGB colors into CMYK colors so that what gets printed looks the same as what appears on the monitor).
