answering for Thomas (hope he doesn't mind), I guess you're referring
to a printer testing process which I intorduced a while back.

I guess you're referring to my printer test procedure here?
A GOOD rip enables proper linearisation - that means that effectively
<<custom printer settings>> can be built.
When constructing the original driver, Epson made the settings for
their papers by linearisation. When we work with the Epson driver all
we can do to <<linearise>> is to choose the best preset they gave us
(even though it wasn't intended for our own choice of paper [and ink]).
