Printer and inkset not specified. Canon and HP also make pigment
inksets for photo printers. Third party ink makers also supply some
pigment inks.


True, but in fall of 2006, did Canon or HP make "professional giclee"
pigment ink printers? Maybe yes, maybe no.

Dye based inks on matte paper are a very bad idea for longevity.
UV is the least of problems to be expected.


According to Wilhelm, Epson dye-based inks on Glossy Photo paper fade
noticeably in 4 years, versus ~ 12 years for Heavyweight Matte paper.
That is a factor of 3, more than the difference between pigment and
dye based inks in the aforementioned study.
