Digital BW, The Print

I've had UT7 inks in my 2100 (2200) for two weeks now and am 
delighted with the results that I'm getting using the sliders in the 
Epson driver.  Clearly there's some trial and error to go through 
for each paper to work out personal preferences but I've achieved 
superb results.  These inks are superb.

But, I first tried the adjustment curves from Paul Roark and found a 
real problem.  I should say first that I've been through all of the 
settings and double-checked everything – but who's to say I've not 
overlooked something!  They're all as per Paul's directions.  For 
every one of the curves supplied (for EEM) when applied as directed, 
the print tones are heavily skewed.  Bear with me as I try to 
explain.  I've printed several step wedges and smooth wedges using 
these curves and all of them print as though they're very low 
contrast.  The 100% black is full black but it rises very quickly 
out of the deep black into dark grey.  It then continues at a 
flatter rate through to light grey then very quickly rises to paper 
base white.  The ramp is nowhere near linear.  It's similar to (but 
not precisely the same as) printing with the contrast slider set to 
minus 25, i.e. it's seems to be very low contrast whilst holding on 
to the black and white at each end.

If it weren't for the fact that I get brilliant results using the 
sliders and UT7 I'd probably have written off UT7 and Paul's 
curves.  But from what I read in this forum and elsewhere it must be 
me and my setup not the inks and curves.

f.y.i. 1 - I use Photoshop CS on an XP Home PC.

f.y.i. 2 - I use a particularly well laid out greyscale available on 
John Paul Caponigro's site -

I must be doing something wrong but I can't for the life of me see 
what.  Can anyone help please?  Thanks in anticipation.
