There are two modes, one is rich black, the other I think is only 
labelled as grayscale, and I get them both confused and so generally 
make both to see which is which. The full CMYK grayscale yields a 
profile with a default name containing the word "gray", the other 
gives no default name and is the black only profile that I mentioned. 
The full CMYK grayscale profile can be used as an output profile 
within the Fiery, the BO profile is not recognised so must be applied 
by converting the image to that space. Made a big improvement over 
just sending a grayscale image to the printer. If you use Norman 
Koren's grayscale test image the 21 steps look real good. The 255 to 
240 graduation that is also on that chart goes up to about 249 for me 
when I convert to the BO space, otherwise I can only get to about 242 
when sending the "raw" grayscale image to the RIP. The steps in the 
21 step chart all look good, and the graduation at the bottom is 
smooth all the way up until the dither runs out on my 9500. Bet it 
looks real good on the 76/9600 at 2880x1440.

I suppose you could do the same thing by adjusting the output sliders 
in level control in Photoshop, but this takes the most trial and 
error away from that process, and gives nice linear steps which may 
not happen using the Photoshop adjustment way. 

Also found out my briefcase is misbehaving, so can't upload anything 
at the moment. The manual is around 12MB and the windows version of 
the software is around 16MB. I suggest just searching the Xrite 
website for "colorshopx" to find the demo (both Mac and Win).
