The color gamut of different proofing technologies and printing processes usually do not match. Part of the color gamut that can be achieved by the proofing system is not possible with the printing process. Trying to match the proof colors with print colors is where a color management system can help.

Using a color management system and the application of ICC compliant color profiles will help to produce quality proofs that will ensure the same color on press. In order for color management to work, rigorous quality control measures must be utilized, kept current, and employed often.
