All images printed on Office Depot Premium glossy paper. The top two images are my control samples. Each was stored in a ziplock bag, away from light. The next two images each spent 3 weeks in my ozone chamber. The MIS inks (left) at three weeks are showing a little bit of shift on this paper, but certainly much less than the OEM inks.

What I think is even more interesting, though, is the bottom left image. This is the MIS ink sample after more than 8 weeks in the ozone chamber. At 8 weeks, it shows less color shift than the OEM inks did after 3 weeks.

Perhaps not so obvious, is that the fade affects more than the cyan ink. As a result the color shift isn't so apparent.
