ICC color management technology can be adopted in a number of workflows. Unfortunately, not all color-management systems, as implemented, achieve equal success in real world. There are a number of factors that limit color management performance. This paper reviews factors such as end user's expectations and color management limitations. However, the objective of this paper is to discuss device limitations and how to use statistics and process control methodology to assess and reduce these variations. Test targets, color measurement, and press sheet sampling are utilized to assess spatial uniformity as well as temporal consistency of hard copy output devices. By comparing temporal variation of the process against specifications, process capability indices, CP and CpK, are used to analyze run-to-run color repeatability. To enhance color management performance, a demerit system, based on amplitude responses, was used to determine the best press sheet for printer profiling application. Color management performance ultimately depends on our ability to minimize and control spatial, temporal, and run-to-run variations.
The objectives of the study was to compare image quality from digital photography to RGB-printer under two digital imaging workflows: legacy-based and CMS-based. Due to the difference in judging criteria, the study shows that legacy- based digital imaging workflow can produce pleasing images as good as CMS-based workflow. But ICC-based CMS out performs legacy-based workflow in matching the color appearance of the source images. This is a welcome feature in direct mail catalogs whereby printed images need to match the appearance of the merchandise closely.
