Summary:
Extensive tests have been performed on a wide variety of color separation equipment, web press runs under standardized production conditions, and scientific measuring procedures of separation films and press sheets. After much confusion and misinterpretation, the gray-component replacement (GCR) process is used extensively now in North America. Newer scanning equipment is capable of producing well-balanced GCR separations. Failures to yield proper results with applied GCR are, in most cases, attributed to problems with the basic color program in the scanner, rather than the GCR routines. One unique feature of GCR is the fact that no one single faction of either prepress, press, or quality control can exert individual control over the process and relies almost exclusively on color computation software in the respective color scanner or imaging system. With newer equipment, GCR, although itself complex, is simple to use.
