Can anyone point me to any current, third-party fade test results for MIS UT-14 inks (or equivalent)?
I found nothing on the Wilhelm Imaging site, but then again I find that site challenging to use. On Aardenburg, I found some old results for MIS, but nothing on UT-14.
On the MIS Web site, they’ve posted 2003 results from their own testing of Ultra-Tone inks, which is somewhat helpful, but these results are 11 years old, aren't independent, and may not reflect the current UT-14 formula. Elsewhere, they say “The Ultratone inks are all extremely archival. Our tests indicate that they will far exceed 100 Wilhelm equivalent years.” But when I asked MIS for a link to the data that backs this up, I got nothing. When I asked MIS about UT-14 specifically, they said “We've never done archival tests on the UT14 inks but the pigments are rated over 100 years.”
I'd submit my own test patches to Aardenburg, but they’ve stopped accepting submissions.
