Sorry for leaving Canon off the list, but they are harder to put a number on at the
present. WIR website says, under the header Canon imagePROGRAF iPF5000: "A review of
preliminary test data indicates that prints made with the Lucia pigmented inks and select
Canon photo and fine art papers will have WIR Display Permanence Ratings in excess of 100
years for color images and significantly beyond that for monochrome images," found a third
of the way down, far right column <http://www.wilhelm-research.com/>.
However on the question... In many past inkset (of any brand) the "yellow ink" is often
the most significant fading problem. Since Epson has been working on permanence for
sometime, they probably have addresses the low hanging fruit. Yellowing of the paper,
through either (a) extinguishing the UV brighteners or (b) yellowing of the coating layer,
was the next area that was discussed in circles I frequent. A few years ago a certain
Epson paper was reformulated and give new name. Recently, I noticed that Epson has
renamed most of their papers, but have no clue of the reason other than marketing.
Now, I'm wondering if the Ultrachrome/K3 magenta ink is the next item that might make the
biggest improvement in Ultrachrome ink permanence.
