I do not know what editor can fix this, but it would need to change the grid

Incidentally, what profile package made the offending profile? Just
curious...

A friend a couple of provinces and three or four states away had
this profile made for him by a local (Epson) dealer. He sent it to
me because of 'grain issues.' Tags reveal no software version or
version number, but it has 8 bit>6gp table A2B0 and a 32gp>8bit
B2A0. Compared to one of my own media profiles (photobase paper) in
Rotator (colorthink) the 3d model reveals it to share the same gamut
width but is very shallow in saturation (less than half) and, of
course, renders the dreaded scumdot.
This LUT configuration sounds familiar, perhaps it's the result of
some of the Color-Savvy-based code? Not sure about that as I think
theirs was limited to 8 bit. I have seen this sig before though...
ColorBlind?
What does it say in the profile header? - also, because those tags
are so cryptic, the copyright tag can be the best indicator of the
creator...
Actually, Joel could you send it over? I'd like to see the effects of
the interpolated scum dot.......
Regards,
Steve
