Digital BW, The Print

In the time I used the VM inks, I never got a good print from them. 
Trying different settings, 1290 drivers and curves (for my 1280). 
Nothing worked, all I got was posterized prints. The UT inks and 
curves worked great right from the start. I'm in the middle of 
modifying the curves and ink adjustments in the Epson driver to get a 
bit more of the tones I'm looking for. 

For a bit I messed around with the Duotone mode in PS and printing 
with Epson color inks. I got some really neat results playing with 
different tritone and quadtone sets. BUT, the color casts of the 
inks/driver is so unpredictable. My opinion is unless you have 
everything hardware calibrated or running a RIP, using color inks for 
b&w consumes too much time and resources.
