Which Linocolor version? Normally Barco's run at 5000K and gamma 1.8.

Generic or rather the batch text data files corresponding to the IT8 that
your calculating the profile for. Otherwise this will NOT work.

Proofing the originals or repro prints?

If your source profile (Monaco) is good and the screen preview is as the
scanned original then if the repro isn't good it's the destination profile
that is incorrectly describing the press. If the screen preview is off then
it's likely the scan profile, or less likely the Barco profile. Do you have
media white point turned on in the Linocolor profile preferences? If so turn
it off to see if this is causing the differences. For such important work
you may consider Profile City's new scan profiler app that builds wonderful
neutral input profiles.
Let us know.
