You could profile the process / processing in this case but remember that
negative films fluctuate greatly in orange mask and exposure density
differences.

Of some reason it only pops up in the reflective popup in Newcolor.
There are no profiles for negative. You can use a calibration file(profile)
for the corresponding color but they will not be the extracted image values
from negative films.

If we assign it in photoshop the result is pretty poor.

Am I all wrong on this, does there exist any negative targets?

Hope someone can give me a hint on this.
I will someday put up a method on my site on exactly how to do neg scans in
Linocolor. For now I'll briefly say ; scan with the tiffrgb calibration
file on negative transparent settings. You can preset the end points as you
like , maybe chroma too. Open in PS , apply a curves layer, click auto. This
will auto range the three channels. Next add another curves and shape the
contrast as you feel. Duplicate the corrected layer and apply this new layer
at around 30% SoftLight. This pulls in most images to print like quality.
Only attempt this on a calibrated monitor as the screen is your target!
When you want more detail, range you have to scan as a calibration scan
(rgb-raw) control base densities, and save this rgb cal scan to disc>open in
PS , invert and go thru more steps, all along in 16bit. That's for another
day though!
