Digital BW, The Print

Greetings, I have recently installed UT2 inks on my Epson 1280 and I am 
using Epson Matte Heavyweigth Paper (8X10). I am following Mr. Roark's 
UltraTone 2 (UT2) Information and Settings using the epson sliders. My 
experiments can produce an acceptable warm print (at least to my 
untrained eyes.) However the cool prints are not acceptable. The cool 
prints are not printing well. Poor detail in the cool prints especially 
where I would expect shawdows to transition to black. Cool prints look 
too blue. My question is are there better papers for warm and cool 
prints. Any suggetion would be much appreciated.

Jim
