I have used SilverFast to create input profiles for my scanner, but although
profiles contain all three intents, they all have the same offset:
If I understand this correctly, the same offset means, that these tags are
all the same.
So in the end this is not three different intents but only one.
My question is, how do I create an input profile for my scanner that contains
tags: AtoB0, AtoB1 and AtoB2 with Argyll?
You can't. It doesn't make any sense in terms of how ArgyllCMS deals with
ArgyllCMS's approach to gamut mapping is to create an overall optimized gamut
mapping from a source space to destination space, and implement that either
in a device link, or in the perceptual and/or saturation B2A table. For this
reason ArgyllCMS doesn't create different transformations in A2B tables, and
(by default) only uses colorimetric A2B tables when linking profiles.
Hope that explains things.
