Anybody got any more info on this? And is it
important?
There's more info on
the ICC website via a slide presentation from HP:
Additionally, a
paper was presented at the Color Imaging Conference in Scottsdale on this
topic;
This paper addresses the issues and
challenges encountered in creating a version 4 (v4) ICC profile. After a brief
discussion of the major conceptual advancements of the v4 ICC framework over the
v2 ICC framework, we describe as a case study the implementation of a v4 sRGB
perceptual and colorimetric color-space profile. Although the ICC specification
defines a reference medium and reference viewing conditions for the v4
perceptual rendering intent, it does not specifically define a reference medium
gamut. Nevertheless one is needed. Within the paper we propose a reference
medium gamut, which serves as a fuzzy target for the perceptual color
re-rendering. It has been presented to the ICC for further consideration. The
discussion of the goals and constraints used for the creation of the perceptual
rendering intent should be helpful for the evaluation of the generated v4 sRGB
ICC profile and for the creation of future v4 profiles. Visualizations of the
perceptual mapping in comparison to the colorimetric mapping and discussions of
potential improvements will conclude the paper.
