Color settings

CMYK (Cyan, Magenta, Yellow and Black) are the colors used in the printing process (offset press), whereas RGB (Red, Green and Blue) are the colors used by screen displays such as your monitor. Your document should be created in CMYK mode so that the colors that you see on the screen most closely match the final printed product. If you create your document in RGB, the colors in your printed product may vary. Many of the bright values produced by your monitor cannot be reproduced in print.

About CMYK and RGB

• Scanners, digital cameras and computer monitors use red, green and blue (RGB) light to display color.
• Presses print with cyan, magenta, yellow and black (CMYK) ink instead of RGB light, and therefore produce a different range of color.

To print on a four-color press, all RGB files must be converted into CMYK.
