Paper Abstract

The saturation rendering intent in ICC color management system has never been practiced successfully. One of the reasons is that it is expected to have primary matching for this rendering intent, but the current ICC workflow makes this impossible. In this paper, three approaches to achieve primary matching for printing applications will be presented. We start with building a printer ICC profile that converts selected first and/or secondary primaries of the default monitor RGB color space to the corresponding printer primaries. If a source monitor RGB color space is different from the default RGB color space, a simple approach is to apply the default RGB color space for the saturation rendering intent for primary preservation. This is because the primary matching is more important than color accuracy for the saturation intent, and different source monitor RGB color spaces are not very different. For more accurate color transformation and still to preserve the primary matching, the source monitor RGB color space is adjusted so that the selected primaries are fully adapted to those of the default RGB color space and the adaptation is decreased gradually as the hue of a source color moves off the selected primaries. In a smart CMM environment, the primary matching can be achieved by hue rotation and gamut adaptation during the real-time linking.
