Color Correction Objectives and Strategies

An investigation of the theory and practice of color correction with the particular reference to the treatment of non-gamut colors. Color correction demands of the printing system, color separation system, original, and the customers are examined in terms of the global adjustments available through the sue of photographic masking or scanner control settings. Two methods of handling non-gamut colors are identified: compress all saturations equally; or ignore the non-gamut colors and reproduce the others as accurately as possible. Optimal color correction and strategies for achieving either outcome are presented. The appropriate use of local color correction techniques is also discussed.
