Digital BW, The Print

Hi,
   I have just set up an Epson 1400 with the MIS UT-14 inks, and
things seem to be working pretty well printing from Photoshop with
Paul Roark's profiles.  But, I would like to try using QTR to get
better control over the toning.  For instance, I find Paul's "warm"
too warm for my taste, so I would like to be able to mix a warm and
cool curve in QTR.

I think that I have managed to figure out how to make QTR curves, but
it isn't very clear to me how to mix the UT-14 inks for different
effects.  From Paul's description, it initially sounded to me as
though his profiles for glossy papers used only the non-black
channels.  I have tried making a QTR curve that just uses the C and LC
inks, for a cool tone.  It does work, but the prints clearly lack the
depth of those generated by Paul's ICC profiles, leading me to think
that there must actually be some Ebony black used.

If Paul or anyone else, could give me some guidance on how to make QTR
curves for this particular inkset, I would be very grateful.

Thanks,
David
