Daniel,

I'm still wondering about your high partition values.  Looking at your 
scan with ink limit=70 it appears that LK would have a partition value 
of about 55% relative to K, if LK were used as the only other gray ink. 
  When I did my 2200 EEM profiles with the UC inks my default ink limit 
was 75 and the LK partition value was 35%.  I don't know if the UT K vs 
UC K is the reason for the difference or something else.  Are you also 
using the 1440x720 Highest Quality resolution setting for printing?  I 
know that these profiles are resolution dependent and quite different 
results would be obtained with other driver settings.
