All images printed on 1st generation Epson Premium Glossy Photo Paper. The top two samples are scans of the control samples, protected from light and air. The middle two scans show the MIS and OEM inks after 3 weeks in my ozone chamber. Again, the MIS inks clearly fade and shift less than the OEM inks in this test.

The MIS inks are showing a very, very slight bit of shift. Where the original image is slightly cool (blue), the test sample is slightly warm. I think this is most noticeable in the gray scale. Compared to the results using OEM inks, however, the change is negligible. And don't forget that my test is very agressive, subjecting the prints to a relatively steady supply of ozone, and a constant flow of moving air. And this is on the first generation Premium Glossy, a paper that is very prone to orange shift.

Finally, the bottom image is the test sample, using MIS inks, after 8 weeks in the ozone test. It shows less shift than the OEM inks did after only three.
