QTR has a moderately user-friendly way to linearize but its grayscale
only.
It can use any measuring device but I use an Eye-One.
Just a very low-level raw version of an old gimp-print is used. None
of the
color code or any of the fancy stuff in Gutenprint is used.
One of the difficulties in a nice GUI from my point of view is
portability --
OSX, Windows, Linux.

As I said in my review, I believe that Gimp-Print is already fully

RIP, Roy demonstrates that but this functionality can achieve
enthusiastic adoption by the less technical photo user community,
provided it is encapsulated.
As far as I'm concerned, with a user perspective in mind, a
user-friendly way to do linearization and ink curves would be a MAJOR
contribution at this time to Gimp-Print - in particular it woudl allow
anyone with a spectro to create a base settings configuration for a
paper/printer combo, which ICC profiling could then polish. I think
that Color Management consultants would jump on the chance to create
custom configurations for their clients as this provides an additional
venue of differentiation.
Roy, could you supply at least a rudimentary but user-friendly way to
do linearization and ink-curves? It would be good to be able to start
from a standard set of spectro readings. A curves editor might be
easily appropriated from the GIMP or even done in Javascript. I know
that I was remiss in not looking how it's done in Quadtone RIP, but
then I was lazy, and you supply some very nice canned settings.
If I'm being unrealistic, please educate me !

I think linearizing the print driver response would be a more
important
factor than having a 16-bit interface.
