Mitch,

That would probably be the best approach. Do a custom dot gain curve for
each ink and paper combination. Since ConeTech is going to offer three
different ink hues I suspect that not all profiles are going to be equal
with each ink set. Ideally ConeTech would have separate profiles for each
ink/paper combination but I don't know what their plans might be in this
regard. Hopefully we will see a Piezo upgrade in the not too distant future.

I feel that the profiles are quite usable with the PiezoTones as they are
with range with the papers I have tried. LPM, EAM, Photo Rag, Museo, German
Etching and William Turner. I am doing work prints on EAM and final prints
on Photo Rag at the moment. In the darkroom it is always a tricky (or
impossible) job to go back and make another print to match an earlier print
using a new batch of paper. Changes in sensitivity and contrast are just a
way of life. In comparison, the differences I am seeing with the inks seem
pretty mild.
