With PrintFIX PRO/Spyder3Print profiles: our recommendation is:
use the Saturation intent, and turn black point compensation off.

Also: now that things are working correctly: my other recommendation
for the R1800 is to use the 729 patch target, rather than the 225. The
R800/R1800 with the extra inks (red, and blue) are non-linear enough
so that measuring the extra patches can really make a difference in
certain color areas (particularly, facial tones).

If you haven't already done so: go to our web site; get the installer
for the Spyder3Print 3.5 "public beta", download and use that instead
of the older PrintFIX PRO software. It's a free upgrade. Also make
sure you download and read the Update Notes that go along with it. One
major difference you'll find is that measurements will go faster; much
faster; and that measuring the 729 patch target will be much quicker,
smoother, and simpler than before.
