Process colors
A process color is printed using a combination of four standard process inks: cyan, magenta, yellow, and black (CMYK). Use process colors when a job requires so many colors that using individual spot inks would be expensive or impractical, such as when printing color photographs. Keep the following guidelines in mind when specifying a process color: - For best results in a printed document, specify process colors using CMYK values printed in process-color reference charts, such as those available from a commercial printer.
- The final color values of a process color are its values in CMYK, so if you specify a process color using RGB, those color values will be converted to CMYK when you print color separations. These conversions will work differently if you turn on color management; they'll be affected by the profiles you've specified.
- Don't specify a process color based on how it looks on your monitor unless you have set up a color management system properly and you understand its limitations for previewing color.
- Avoid using process colors in documents intended for online viewing only, because CMYK has a smaller color gamut than a typical monitor.
