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.
