Hi Antonis,

I've been using an 1160 for quite a while and I just got a 7500
(still working out some connection issues I think).  
Both have VM-Sepia in them.  I discovered gimp-print as a
way to use old printers on OS X.  The GP software has a lot
of great stuff in it -- lots of printers, lots of dithering capability,
lots of different ways to lay down dots.  The two things that
have concerned me a little were the linearization of individual
inks and the light/dark ink transitions.  Working with the 1160
has been quite easy but I haven't done much on the 7500 yet.
I've just done it "by hand" so to speak with a little help using
spreadsheets.

Anyway, it looks like the Bowhaus guys have addressed both
of these issues.  It looks like you tested it out with a 2200 --
is there any help/automation in designing the shape of the
curves i.e. partitioning inks?  For instance, how was the
light black to black transition formed?
