Right. That makes sense. Thanks a lot
Tom. I can see where the UT7 curves will be better. I really need a
custom curve as the canned ones are coming out very dark.
Thanks again,
Tom

You're finding out what I learned - making curves for the UT7 inkset is a
little more complicated than the UC, but not that difficult once you've done
one.
Generally, (or at least so far) I don't use the toner curves with UT7 and
matte paper. For a cool curve for Matte the L, M and LM inks used as grey
inks. For a warm curve (again for matte paper only) the K C and LC are used
as grey inks. A neutral image is achieved by blending a warm and cool curve
when printing.
For glossy and semi gloss papers such as Epson Premium Semi Gloss, the K ink
is not used. In this case, for a cool curve for example, the M and LM are
used as the black inks and a little bit of C is used in the deep shadows to
achieve the best possible dmax. Look at the Ilford Smooth Pearl curve as an
example.
Basically, with QTR any ink position can be considered to be a grey ink. The
"K" ink is that grey ink with the greatest density - it is assigned 100%
black and the density of the others are defined with respect to that ink.
