Digital BW, The Print

I thought I read on the MIS website somewhere that the Ultrachrome 
and UT7 inks have a heaver pigment load and can't be pumped through 
a dye-based ink printer.  Paul and Clayton, do you know if this is 
true?  If so, since the 870 is a dye-based printer (if my memory is 
correct), then would the UT2 inks have too light a pigment load for 
the 2200 and give too light a print without a custom curve?
