Thanks for the info Paul.  I'm curious about the composition of the UC 
matte black ink.  I tried printing a few images using only the matte 
black ink through the Epson driver on a 2200 (at 2880 dpi) on eclipse 
satine.  I expected to see a relatively neutral tone, but the prints 
exhibited a warm tone (almost brown) that was actually quite pleasing 
for some of my landscape images.  Is this typical of the carbon based 
pigmented black inks in general?
