Digital BW, The Print

After printing PS tri- and quadtones for a few years I switched to 
MIS-VM inks on EAM paper a few weeks ago and noticed a dramatic 
improvement in the range of tones captured and in, at least, what 
appears to me, to be the overall definition of my prints. The MIS-VM 
inks also seem to be much more consistent.  However, comparted to PS 
tri-tones printed on Sommerst Velvet Enhanced paper, the prints on 
EAM seem to be a bit flatter, what I can only describe as lacking 
some of the "life" of the PS tri-tones.  I have experimented with 
layers set to "overlay" varying the opacity, and with attempting to 
increase the contrast in various ways, which helps, but something is 
still missing in terms of "sparkle" or "snap."  The prints are far 
from flat, but something is missing.  (I scan in 16 bit.)

Is this simply a characteristic of EAM?  Would an alternative paper 
such as Hahnemuhle Rag make a difference?  Or, as I suspect, is this 
just a matter of technique which will come as I gain more experience 
with the quad inks?  I am quite sure that my settings are correct for 
Paul R.'s curves.  I print on an Epson 1200 and do not have problems 
with banding, etc.  

Sorry for what, at least for this list, is a very elementary 
question.
