Hi Richard,
the simplest way of doing a test is to use the built in
fake display device/instrument. If you feed dispcal/dispread/etc.
a "-d fake" parameter, they will use the profile "fake.icm" if present,
or if not present, will use a built in fake RGB device response. So my
sanity check is something like:
dispcal -v -m -d fake test
[This is not in the documentation, but there is a comment at the top
of each tools source file, as well as a commented out usage line.]
Cheers,
Graeme.
