Its often easy enough with a RIP to increase the amount of ink in a black 
mix, resulting in a darker black. Getting a sharp, non bleeding result with 
smooth gradients through the dark tones is always a challenge with heavier 
blacks, but simply laying down more ink is easy. On some media, adding more 
ink may not make the resulting patch darker, on others it may. I'll admit; 
paper white is pretty much a fixed limit... but max black is not.
