Martin,
if I remember the discussion about FOGRA52 the conclusion was:
There are gamut mapping algorithms out there which give decent results using
the new characterization data.
It’s just that they are not inside the profilers you have currently access to.
Correct?
So why don’t you simply buy a decent profiler, create a profile with a mapping
that you prefer and give these profiles to your clients?
My 2 cents
