I think those Eboni 1800 3-MK results on Premier Art 205 (aka Epson
Scrapbook paper) are the best I've ever seen.  At 100 Mlux-hrs the average
as well as worst 10% I* Color scores are both 100.  The average I* tone is
98.7, and average delta-e is 0.2.  The worst delta-e is the paper at 0.5.
 The 50% patch delta-e is 0.1.

Your test strip was also sprayed with Premier Art Print Shield.  Sadly
there is no sample on that paper that was not sprayed, for comparison.  The
performance of the sample is certainly aided by both the paper and spray.
 The informal testing I did with that paper showed it to be the best I ever
tested.  Epson at one point also said that the Scrapbook paper was its
"most archival" (whatever that means).

The spray on the sample also makes it hard to compare to other
Aardenburg-Imaging samples.  The only Epson UltraChrome ABW samples that
are sprayed are on glossy Ilford Galerie Gold Fibre Silk.  At 90 Mlux-hrs
that sample has a 50% delta-e of 1.8.

At any rate, I think the Eboni 3-MK on sprayed Premier Art 205 (Scrapbook)
paper sets the benchmark for lightfastness in these tests are far as I can
tell.
