Intents deal with out of gamut colors. Paper white and ink black compensation 
work with "out of gamut" blacks and whites instead. There are no out of gamut 
colors (or any colors to speak of) in gray systems. But you still need to 
stretch the profile to print from paper white to ink black, not clip the ends as 
it would without these adjustments. If you look at the Ref Black and Ref White 
functions in PrintFIX PRO you will see that these allow adjustment for 
differing degrees of preview adjustment to paper white (both warmth, and brightness) 
and ink black (tint matters less here, its mostly darkness). These functions 
are to fine tune the white and black (and everything in between, as effected 
by white and black) of your softproof preview to improve your screen to print 
match, without actually changing how the profile prints. Same idea, but for 
color work, or for black and white printed with color profiles.
