Hmm, I guess it is just Profile Maker 5 that creates ICC v2.4.0 Matrix profiles with A2B and B2A tables. Any idea why they would do that? Here is an example: http://www.mediafire.com/?e3nn113ohmw
If it's got A2B and B2A tables, then it's not a matrix profile ! It sounds like it's a combined profile with both cLUT and matrix tages, which is what we were talking about before. [ I have seen profiles that have both a matrix and L*a*b* cLUTs, but although they may work with some software, they technically aren't complient with the ICC spec., since the PCS label of L*a*b* is inconsistent with the matrix. ] Graeme Gill.
