[argyllcms] Re: how to verify measured target values

Mike,

you could compare the measurements with the profile output of the same 
Cmyk colours. This is possible in ICC Examin with feeding the profile + 
the ti3 files at once. You should then be able to select from the 
main window "View"->"Quality Report".

But the relyability is a bit reduced as these values where formerly used 
for profiling. A clever profiler may try to optimise for just the 
measurements and pays bad for other colour areas. So take such 
comparision with a grain of salt.

Better is to test with a extra set of measurements not used for profiling 
and compare how these play. ICC Examin, and similiar tool, will report much 
more relyable then.
