Digital BW, The Print

I've tried some test prints on EEM paper using these inks using both 
of Paul Roark's workflows (slider adjustments and adjustment curves). 
I'm quite certain I've followed his instructions to a "T", but for 
some reason, two things keep happening: 

I keep getting vertical banding 

The prints are very much on the warm side and much lighter than they 
should be even when I'm using UT7 2200 EEM-1.acv

Again, my settings for source space, print space and color management 
all seem to be correct. I even checked that I had the carts in the 
correct positions (I'm using Ebony Black UT7-T0348) and still I'm 
having NO success in getting anywhere near to a decent acceptable 
print. 

Any suggestons?
