BPC is a run time luminance range mapping, which is useful in making working
space RGB profiles talk to real world print profiles without clipping the
black response. It is a simple form of gamut mapping. You can avoid
the need for BPC and have more nuanced control over the mapping
if you create and use ArgyllCMS perceptual profiles appropriately.
