Digital BW, The Print

This is one of the big plusses of the Posterprint RIP. First you linearise
the RIP for each inkset, then you can tweak the black laydown, then you
profile for each paper/ink combo. So you get a driver that doesn't compress
tonal values and then optimum black flow and then profiles to much the ink
to the paper. A major difference between this and IP IMO - you never wait
for 'support' for an inkset - you just calibrate and go.
