It is good to see some data.  I've always liked the fact that MIS published
its RIT test results for the MIS Archival inks.

It looks like there may be an error in the MIS FS delta E calculation in the
fade results Cone Editions released.  The FS K faded less than the Portfolio
black, yet is listed as having a higher delta e.

I'm also not sure about note 3 on the "Test Condition."  It says,
"Lightfastness: Irradiation UV (Xe) 10,000 Kj/m2/200 hours."

If the lamp was strong UV, then I wonder if the results correlate well with
actual lighting.  Most of us are oriented to indoor display, where the UV
from fluorescent lights or window-filtered (thus no deep UV) light is the
main problem.  Unlike the outdoor signage market, I don't think we have that
much of a UV problem with our prints.

I'm a little surprised that the carbon sepia did not do better.  I would
have thought that an ink that was supposed to be pure carbon would fade less
than inks that have some color pigments in them to get the tones that are
popular.

I'll run my own tests as samples are provided.
