One of the ways to create a ColorCast profile is by “concatenating” four ICC profiles in a Color Worksheet: the Lab profile, a proofing profile (direction: Lab -> device space), a proofing profile for the second time (direction: device space -> Lab), the “host” device profile.
Which profile tables of the host profile will be influenced? Just a single B2A table? Which? All B2A tables? Configurable? Also A2B tables?
Which of the profile tables of the proofing profile will be “incorporated” in the host profile? Configurable?
Is it possible to use a different rendering for the first and the second time the proofing profile is “incorporated” in the host profile? For instance: first time B2A0 (perceptual) and for the second time A2B1 (colorimetric).
More generally: is there a more precise specification of ColorCast profiles and ColorCast profile creation?
