I realy enjoyed using this paper, very pleased with the results from my epson R1800.
The profiles from the manufacturers web site seem reliable, although I had problems with yellow saturation, but this was easy to resolve.
The only down side is it needs carefully dusting before use, or it can flake off leaving white marks on the print. I use a microfibe cloth to wipe it down before loading into the printer. This is the only reason for 4/5.
