Digital BW, The Print

Hi Mike,

Yes, there are two configurations.

The latest and most talked about is UT7 or also called the Roark
configuration -- this will work with the Epson driver.

The older one is under UT and also called Bowhaus or QuadToneRIP
configuration -- this requires one of the rips.

What you are asking about doing -- trying UT7 with Epson first
and then possibly moving to QTR is certainly possible.  The catch
is the "just make a profile".  To do that you have to look at the individual
inks for both color and density and come up with a plan of how they
might fit together to make a neutral tone throughout.  The plan is
a lot easier if you have all similar color grays and separate toners
to give the color.  With the different densities having different colors
its just a lot more difficult.

That said, most likely I'll end up making some UT7 profiles some
time.

Roy
