Ben,
I can understand your frustration, but that's just the physics of the
situation. We often think of metamerism as a bad thing (none of us like to
encounter metameric failure, as you have described in your posts), but
metamerism is the mechanism that allows us to use just four printing inks
(sometimes three, sometime more) to represent a large gamut of colors.
Without metamerism, we could not do this.
The trade-off is that we are making metameric prints, which means they are
dependent on the illuminant. The solution to this dilemma is a new technique
often called "spectral printing", which is currently a hot research topic in
the color science and printing circles. With a limited set of printing inks
(even six, or eight), you will never have a print that looks correct in all
viewing conditions, but with spectral printing, we will be able to optimize
our prints for more than one illuminant. I've seen prints that look correct
under both tungsten and D50!
It will be a while before we see this in common use, but it "is" on the
horizon…
Ken
