My own measurements of both Epson Premium Luster and Hahnemuhle Fine Art
Pearl showed these results:
1) The Epson Premium Luster paper has a fluorescence peak at 440nm measuring
between 94.1 and 96.4%, depending on the white patch measured. The Lab
values for the paper base are in the neighborhood of L 95.7, a -0.2, b -3.7.
2) The Hahnemuhle Fine Art Pearl (FAP) shows a fluorescence peak between
107.5 and 108.5% at 440nm, and its paper base reads around L 98.2, a 1.4, b
-4.4.
Side by side under a black light, Hahnemuhle's FAP appears a strikingly more
brilliant blue than the Premium Luster, whose lower fluorescence ends up
looking rather "dull" by comparison.
My conclusion (unscientific as always!) is that, though the Premium Luster
stock reads as having a lower brightness, that may be due to the fact that
the Fine Art Pearl paper's brightness has been artificially enhanced by
using a distinctly higher OB content.
Due to the tendency of OBs to yellow in time (not a desirable outcome for a
fine art print), I find it a strange decision on Hahnemuhle's part to have
loaded its FA paper (which is advertised as a "fine art" stock) with such a
high OB content. Personally, I would think that a fine art print should be
made on papers with as low an OB content as possible (ideally none -- though
that is probably a pipe dream, given that we have been so conditioned to
demand brightness in our papers, and OBs are a convenient shortcut to that).
