Digital BW, The Print

None of the results posted here regarding the quad pigment inksets are relevant if you are printing on uncoated papers. 
There is no ink/coating reaction, so even with the warmest ink combinations they will appear relatively neutral. Mottle, 
bleed, and posterization are definitely greater with pigments on these papers. By the time the ink is throttled back enough 
to control these problems by various means, color gamut and max black are reduced to less than where one would wind 
up with dyes after addressing the same problems.
The various curves being used will probably not be very useful since they were developed on coated papers.
That's my experience with Piezo, Generations, older MIS, and Lysonic inks. Bob's post about the MIS hybrids might be worth 
pursuing though. Steve Meyers has a lovely older print on Somerset Velvet with an old MIS color set.
For color inks, media setting tests and good profiles would definitely be in order.
