I recommend the free software
ArgyllCMS
http://argyllcms.com/
with DispcalGUI for ArgyllCMS
http://hoech.net/dispcalGUI/
and with chromatically coordinates white point (recommended) is:
x: 0.326
y: 0.336
for accurate Whitepoint
I have spent a few weeks working with the Windows version of argyllcms via the command line. With what I now know I’ll give the GUI a try.
The results compared with those of i1Profiler are such as to wonder why X-Rite remain so obstinate in their refusal to offer CMY only profiling.
If you don’t mind getting your hands dirty then argyllcms is a powerfull choice for handling the jobs other tools cannot do.
I haven’t quite got it mastered as it takes a little time to experiment and learn how to utilise the variety of options available at each stage of the process. Actually I think I am still ‘painting the fence’ but the results are better than achieved with i1Profiler and its inflexible user interface…
