Hi Joost.
Gutenprint has all the capabilities but--I think, for B&W, that QTR is
still the one to beat. It's (QTR's) facilities for curve generation
and ink limiting are an advance over those currently in gutenprint, in
my estimation. It's not that gutenprint can't do the same things. It
is just that it is not as friendly to use with instrumentation. A jump
from what you describe as your current level with QTR to learning how
to make advanced curves is likely to be much easier than starting over
again with gutenprint. You already have all that you need for the
task. If you haven't done so yet check out Paul Rourk's site for all
the information he has set out for doing the sort of thing you are
looking for with QTR. He has written some tutorials on the topic.

 I still use QTR for all of my B&W printing. The only reason I began
exploring and using Gutenprint is because I had to have some sort of
an advanced RIP for color work that I've been doing. I only wish it
had some of the same functionality that QTR does. It would make it far
easier to use and learn. As it stands, a lot of the parameters in
Gutenprint are still buried within it's drivers. You can make
adjustments to them but, unless you look at the source code itself,
the base parameters are not directly visible to you so your changes
are made somewhat blindly. They are not set up as log10 density or Lab
values or percentages etc. Also any color management has to be done
outside of gutenprint. I hope all that will change as time goes on but
it may be awhile.

Hope this helps.
Duane
