Abstract
The disclosure is directed to techniques for gamut mapping with modified black point compensation (BPC). The gamut mapping techniques promote well-distributed tone compression so that substantial loss of detail in highlight and shadow regions can be avoided. The gamut mapping techniques may be particularly useful in converting rich saturated images, such as RGB photographs, for presentation as much less saturated output, such as typical newsprint. Other example applications include conversion of CMYK Specifications for Web Offset Printing (SWOP) printing to CMYK Specifications for Newsprint Advertising Production (SNAP) newsprint, and conversion of RGB photos with camera profiling software to CMYK for all types of printing.
