3.X made good profiles but lots of people complained about the lack of
saturation in the finished profiles. If you are going to Seybold, you'll
likely hear and see some vast improvements from this company. So hold onto
those spectral data files!

I've got a 3000 and haven't seen this either. Does doing a calibration
routine pull it back into line?

Where am I missing the bus?
GretagMacbeth made a recommendation once that seemed odd but is certainly
worth a try; use the Saturation intent! One other thing I find is that I
usually prefer output with these profiles using a Relative Colorimetric
intent. However, it's an image by image situation. So use the Convert to
Profile command (since you need to anyway for the Fuji) and toggle different
intents and pick the one you like based on the soft proof you get.
