The Pro-100 & 9000 MkII both use "Dye" based inks. The Pro-10 & 9500 MkII both use "pigment" based inks. The pigment inks are supposed to last longer and reproduce B&W prints with more depth and contrast. The "dye" based ones are better for producing bright & vibrant colors but they will fade faster. Today's modern high-end paper, for the most part, has (pardon the pun) blurred the lines between these two inks.
Check out this website for info on selecting the right type of paper to make "dye" based inks last virtually as long as "pigment" based inks on paper... Dye or Pigment? Facts you need to know.
According to Wilhelm Imagin Research, the PRO-1 using the latest semi-gloss is only good for 36 years (not framed), 71 yrs (framed under glass), 138 yrs (framed under UV glass, and >200 yrs in dark storage. I'd love to see WIR conduct a test using the reformulated dye inks used in the PRO-100. http://wilhelm-research.com/canon/CanonPixmaPro-1.html
What is very interesting are the results of other papers using inks from Canon, Epson, and HP. The test of the Canson Infinity Line show values that are amazing. http://wilhelm-research.com/Canson/canson_infinity.html
One paper for example: Canson Infinity Rag Photographique
Epson: 36 yrs (no glass), 69 yrs (under glass), 125 yrs (uv glass)
Canon: 56 yrs (no glass), 108 yrs (under glass), 199 yrs (uv glass)
HP: 85 yrs (no glass), 219 yrs (under glass), >450 yrs (uv glass)
HP inks really last that much longer? greater than 450 years if framed under UV glass? Now that is permanence!
