Aardenburg Imaging has no solvent data last time I checked....
...That being said, I want an archival one
The AaI&A Printmakers' testing fund pretty much got wiped out on the last round of samples I put into test, so I'm waiting on more donations before I can take in more sample submissions from AaI&A members, but I will be more than happy to test output from this new line of Epson Solvent printers once the funding is there and a member wants to submits some samples for test. The fact that the ink is formulated with a solvent other than water is irrelevant to the Aardenburg testing methodology, so the test results will be directly comparable to any other samples in the AaI&A database except for the white and metallic inks which will require a modified test target. Those unique colorants will require a non standard test target to incorporate those colors, but other than that the I* color and tonal accuracy metric I use can test any color set you want to throw at it.
In lieu of any independent testing, however, reading the "longevity" claims from Epson's own published literature on this new Surecolor solvent printer technology strongly suggests that the final image permanence will be highly dependent on image content., i.e., Epson claims the CMYK colorants pass an outdoor durability rating at 3 years, adding the orange ink drops it to two, adding the white pigment drops it to one, and adding the metallic ink comes in at a very surprising limiting factor of only 3 weeks! Yikes! It would be very interesting to determine how it will hold up for indoor display environments! My guess is that artists will be very interested in harnessing the white and metallic pigments for their own creative output, so this tecnology is indeed likely to show up in galleries and in museum collections in the very near future
