I'd be interested in knowing the results of any tests concerning the 9000. I had a look at the link and it seems to me that the results Wilhelm stated were for the 9500 (a pigment ink printer). The Canon announcement is pretty vague, it doesn't really address print longevity for the 9000. Jim
The 9000 seems to use ChromaLife inks; my 9900 uses what I think is one generation earlier, the dye BCI-6 inks. Canon states these will not show noticeable fading when printed on Canon Photo Paper Pro and framed behind glass for 25 years (see the PhotoPaperPro product page on Canon's website). I assume they also exclude frequent sunlight across the framed print.
Ilford says their Galerie papers, with Canon dye inks, behind glass, will be "comparable to photographic prints" but didn't give me any specific numbers. It's probably too hard to characterize a reasonably general exhibition environment, so that makes it not possible to publish harder numbers.
However I am quite happy with the colour capabilities of the printer.
