Note that their best consumer "Ultima" paper is diabolical with pigment
printers, and their professional range will give poor longevity with dye
printers. I would seriously question why anyone would even use Ultima
for serious dye ink printing. Divide Kodak longevity claims by at least
five - as a starting point - for comparison with reputable
manufacturer's statements. Using Kodak methodology, a pigment inkjet
print displayed behind glass should last 1,000 years.
