Okay, then let me supply you with a second object to get this back under the
heading of metamerism. If I print two copies of the same image, one on an
Epson 2000p, and one on a LightJet, and balance the Epson image to match the
Lightjet image at one light temperature, then the LightJet print will still
hold appropriate skintone balance under differing lighting, while the Epson
print will not. the Epson print's skintones will appear more yellow or more
red (or even more green) than the skintones in the true photo process print.
Yes, the LightJet print will change (as any object will) with differing
lighting, but not in variable, unexpected, extreme, objectionable ways...
that kind of differential change is what is being referred to here.
