Hi Theo, > How can one setup in lcms something like dev-dep ICC -> ideal independent > ICC ?
It is easy: just use an XYZ profile as output, ICC2 in your workflow. lcms has a built-in XYZ profile to do this: cmsHPROFILE hXYZ = cmsCreateXYZProfile() A couple of notes: A good choice for encoding in this case would be TYPE_XYZ_DBL, which will allow you to transform directly to cmsCIEXYZ type. And note that in ICC notation, XYZ get normalized to 1.0, that is, D50 is represented as 0.9642 1.0 0.8249, which is not the usual 96, 100, 82. To get the "normal" numbers is just a matter of multiplying times 100.
