At least based on a quick read, the results look consistent with what I would expect. Matte paper, un-mounted, appeared to do the best. RC paper, mounted, gets micro-cracks.
I don't know the limits of the test procedure they used. It's different than what I have heard of before for age testing. Still, it did not appear to cycle the temperature and humidity.
Consistent with the test, if I wanted to make the best glossy mounted printn, I would consider using aluminum. On the other hand, given the use and markets that I have in mind for glossy, I'm not sure it matters.
I would still bet on un-mounted Arches (un-coated watercolor paper) looking the best a few centuries from now. But, I don't expect to live that long. So, to enjoy my images the most, I have mounted, un-glazed B&W dye prints on my office walls, plus one 100% Eboni carbon on Arches print hanging under acrylic on a different wall, in part, to remind me that what I believe to be the ultimate in longevity can look great even when my top, relatively short-lived dye eye-candy prints are also on display.
It's good to see some testing going on and being disseminated. Thanks for posting.

Interesting article thanks for sharing it.. Your right everyone will have their own opinion.. What I can tell you is that within museum conservators you will find varied opinions.. I went thru this with Gator board and similar materials some years ago.. I will try a few searches to see what I can come up with relative to aluminum. What I learned with gator board was that a proper barrier was necessary between the image and the board.. So in the tests that Queens University did it is certainly a valid test but tests typically raise more questions or what if's?? The first that comes to mind is the bonding tissue used.. Is it a valid archival barrier and bonding agent. Regarding the fact that the Premium Luster failed quicker or had more negative effects then a cotton material doesn't surprise me at all.This is a pretty good group and you have a pretty good topic here.. hopefully a few can offer some insights..jimbo----- Original Message -----From: ben@...Sent: Wednesday, October 23, 2013 9:52 AMSubject: [Digital BW] Best way to mount printsHi,
I recently found this 'scientifical' document about the long-term effects of mounting digital ink jet prints to Aluminum and Dibond supports.I wonder if the traditional setup print+passepartout behind glass is better or not.I talked with several people about it, but everyone seems to have his/her opinion.Can I find somewhere good research results about this?This is the doc I talked about in the beginning: http://www.queensu.ca/art/artconservation/research/projectsMAC/TessaThomas.pdfThank you,Ben A.BelgiumNo virus found in this message.
