This is a drum scanner coming in with RGB, going to an rgb working
profile such as AdobeRGB before printed, channel crossing visible in
rgb working space.

I meant that if I take A.ti3 and make a profile, it will give 1 delta
E, B.ti will give 1 delta E also on it's own, but once I combine the
ti3s it gives a delta E of 2-3. (symbolic values) Is this because of
the change of standard deviations? They are the same ti3 files, so
there is no changes in the process or input values to colprof

thanks a whole bunch,
