Digital BW, The Print

I've just installed UT7 inks in my 2200 (eboni black), but I get
really weak blacks using the Paul Roark smooth pearl and epson glossy
curves on Ilford/epson paper respectively. Images also look a bit
grainy. I have tried printing on matte papers (EEM) and this seems
fine with either curves or using QTR. I must be doing something wrong,
but I can't figure out what. I previously used the UT2 inks in a 1290
without problems using the same glossy papers.

I am using XP, setting space=adobe RGB, same as source, in PS. 1440 
dpi, EEM paper, high speed off, no colour correction in the driver.  I
get perfect nozzle checks.

Anyone any ideas?
