Yes, we tried that ink some years ago and did the
same experience. But as the new color ink should
be a clone of Epson UC (they say) it would have
been nice to know if it worked together with
transparent medias.

Maybe we did something wrong but we can't
understand what. Everything seemed to work as the
instruction told and the curves looked as
expected.
Our idea to use QTR for neg was the possibilty to
disable the toner (hex ink) and trying to
"strangle" the black.
We made our linearization for the 7500 (ordinary
b/w printing) but as we couldn't get it to work
we did never continue with the neg idea.
What DR do you achive with your setup?
