Digital BW, The Print

I've just taken delivery of an R220 plus UT-R2 Warm Print inks. My 
initial tests on various matte papers have been very encouraging but 
I'm stating to wonder if the warm effect is, well, a bit too warm for 
my personal taste.
I've read some of the info from Paul R on warming up a Neutral set of 
inks but I'm not sure if I completely understand what I would need to 
do to cool down my warm set. Using EZ-Warm ink was mentioned for 
warming a neutral set but I'm not sure what that ink is.

Any suggestions gratefully received.

Peter
