Peter,
It sounds as though Nikon has a convoluted form
of color management that is trying to lock you
into their proprietary color management system.
I would want to use an open architecture such
as Apple ColorSync or Windows ICM.
This is the methodology I would use:
I would characterize the scanner with the IT8.7/2
or Q60 target. Then I would create the scanner profile.
Next, load the scanner profile into the colorsync
folder on the Mac or Color folder on a PC.
Now I would test the integrity of the profile, by
scanning the IT8.7/2 target, using the newly created
scanner profile.
I would scan the IT8.7/2 target with and without the profile. Next proof the
scan and verify for yourself
that the scan with the profile does match the original
IT8.7/2 target more accurately than without the profile.
I hope this helps.

I scan my 35mm slides with a Nikon scanner whose software can be used as a
stand alone or as a Photoshop plugin. In either case, I scan the film with
no exposure or color adjustment (as I made the profile) and then assign the
scanner profile to the image, then convert it to my working space, Adobe
RGB.
If I scan as a Photoshop plugin, the image is tagged as Adobe RGB (my
working space), to which I assign the scanner profile and then convert back
to Adobe RGB. If I use the scanner as a stand alone, I get an untagged RGB
file, that I save as a tif and then open up in Photoshop, followed by all
the assigning and converting.
The question is: am I losing something by starting with a tagged file
before assigning it the scanner profile? I thought that it might, but when
I tried it, my eyes didn't see a real difference on the screen between the
file that started tagged and the untagged image once they are finished,
corrected images, ready to print on one of the Epsons. Using Nikonscan as a
plugin is convenient, but I can live with a few extra steps if it is going
to make a difference down the road.
All words of wisdom, caution and/or experience, gratefully accepted.
Thanks in advance,
