PrintFIX PRO profiles are capable of controlling tints as well as densities, 
when used with a driver or RIP that allows the profile to do so. So if you 
profile a grayscale driver, you'll only get density, as the a*/b* components will 
be ignored, while profiling a color driver will allow you control of color 
tints as well as density. A 9500 will require a custom inkset to do good B&W 
printing. If you choose a profilable singletone or adjustable tone inkset, then 
you can profile it with PrintFIX PRO. That profile will then allow you to tell 
what is, and is not, in the gamut of that inkset, for the adjustable B&W sets, 
and preview the results at various tints and crosstints. For the single tone 
B&W inkset, a PFP profile will preview that tone, and allow you to adjust 
densities with a live preview of the results; but the tone will be fixed, and will 
vary a bit from paper to paper.

For more info, download the PrintFIX PRO 2.1   UserGuide.pdf at 
colorvision.com, under Support >User Guides. The tutorials on B&W, as well as the screen by 
screen help, will tell you more about the process.
