Whatever they're doing, if you look at a plot of the gamut, you see that they're often showing that the printer / paper is capable of outputting L=0, a=0, b=0, with a huge color range at L values not much higher. Considering some of these papers don't even come close to single-digit L values, I think it's safe to suggest that there's something not kosher going on.... Cheers, b&
