Using the Right Color Palette
The printing process is based on four colors of ink: Cyan, Magenta, Yellow and Black (CMYK). Each color is added separately as the paper passes through the press. This is why you may hear it referred to as a Four Color Process or Four Color Printing. Also why you may see your printer refer to a file that will be printed on each side as 4/4. Meaning, four inks on the front and four on the back. A job to be printed only on the front would be 4/0, etc.
