I have used Profile Prism several times - always easily and successfully but not for awhile.

I have not been able to reduce the warnings for brightness on canvas gessoed (matte) and coated with InkAid:

WARNING: 29 patches marked with "X" are at minimum/maximum brightness.

They are all red 'X's in the lightest (top) patches.

It seems most probable it is a limit of the coated canvas but ask for input in case I am making an error. Dynamic range (70.1) and ink coverage (9.9%) are understandably low while smoothing required is acceptably 4 passes. If "Printer profile usable range: 51-255, 51-255, 51-255" could be boosted it would be nice.

Can anyone tell me if it is simply a limitation of the coated canvas?
