This doesn't explain anything, unless they are using a very,
very non-standard observe model, or very, very strange
lighting spectrum. In either case, this would make their
ICC profiles completely incompatible with anyone else's.
I agree. But a while back I took spectral measurements of Scan-Am
Profiler targets and was trying to build 3D models in Craig Kloeden's
Rotator. Results went from horseshoe gamut to stretched-egg gamut,
low saturation but very few holes...smooth transitions overall. Of
course they were whacked for any real use, but I wish I'd kept that
data to hum and haw over.
Several ImagePrint profiles have interesting 'shapes', low
saturation, smooth transitions, no holes....
But really I'm fishing in water way over my head...;0)
