Digital BW, The Print

Unfortunately, ICC is a standard that was developed specifically for color. While 
there is "space" in the format to characterize quad and hextone b/w, any 
software taking advantage of this has to be configured specifically to do so. To 
date, when companies have developed this capability (ie Colorbyte) they have not 
been eager to share the secret sauce. This may soon change, as more imaging 
companies develop for b/w.

You will always be better served using a good driver and optimally a RIP to take 
advantage of any profiling. Your RIP has to be able to output a target that the 
spectrophotometer can measure properly, and the profiling software has to 
receive this data in a compatible format. Then, the RIP has to actually be able to 
utilize this non-standard (ie non-CMY) information. Many color print makers use a 
RIP, spectrophotometer, and profile-generating software each from a different 
company, so the idea of compatability does exist in the color world.
