Re: [bcm] Some issues with ICC based color management in the real

Hi Olaf, I have been looking at your presentation and look forward to discussing it in further detail next week at the ICC meeting. In the meantime I have some simple questions: (1) You mention as part of your proposed solution: "output intent must consist of - CMYK output profile - information about tone value increase" What information do you think the tone value increase would add to that already present in the ICC profile? Have you considered the possibility that TVI can be estimated from the ICC profile? There may also be better measures for the future than that of TVI, for example a measure of dE relative to the paper. This measure is available from the ICC profile. This would mean that PDF/X-3 documents already meet this part of your requirement. (2) The addition of a new rendering intent [Maintain Colorants] is an interesting idea but I think needs further definition. It is clear how the 'Maintain Colorants' intent should map colours that use only a single colorant but how should C=M=50% be mapped? And what about CMYK [20,30,10,20]?
