You need to load TIFF RGB as the calibration (profile) to null the scanner.
Also ensure that your color assistants are turned off and everything else is
set to standard. I also set the filter (aka sharpening) to none. Then use
the Calibration scan to disk function everything should work well. Loading
the TIFF RGB profile is sharpening base ICC profile for scanner calibration.
This is wrong.
Linocolor 5X was not entirely based on ICC profiles. One of the
internal options was to convert from scannerRGB to TIFFRGB on the
fly. This option appeared in the Import plug-in for each scanner (at
least those I know of). I do not have LC5X loaded on any of the Macs,
but if I remember rightly the option was called Standard RGB in the
Import plug-in.
Linocolor 6X is based entirely on ICC profiles. There is no internal
conversion, not even an internal default CMYK conversion. If you
remove all CMYK profiles from the ColorSync folder (you can only do
this in CS versions prior to 3.0), the image window goes gray if you
select CMYK simulation with a color image open.
The reason is that the simulation chain can't be built (other
software will default to an internal, unknown CMYK which IMO is
deceptive, but then again I prefer my CMYK dry and neither stirred
nor shaken -:)).
The ICC profile you load in the 'Calibration' popup in the Import
plug-in has nothing to do with the 'Calibration Scan to Disk' command
(which is misspellt as 'Calibration Scan to disk' and has remained
misspellt for as long as I can remember).
Again the problem here is that the UI strings confuse the living
daylights out of users even if the application is perfectly logical
and quite foolproof, compared to say Photoshop.
(And I am not saying the LCh color correction tools in Linocolor 5
and 6 are everything I would want, only that the profile chains are
correct and consistent to a fault.)
