Digital BW, The Print

I concur with what John has said.  I use Lascaux for matte paper to avoid
dmax loss and Premier Art Print Shield (the solvent based one) for glossy
paper to get the best dmax and hide the bronzing better.

If I were doing Epson color, I might use Premier Art for that even on matte
for the UV protection, which Lascaux does not have.  In my tests Epson
pigments fade at about a 30% lower rate with Premier Art, whereas MIS
pigments only get about a 10% boost.  With custom B&W inks I've made from
Epson pigments, this spray brings them right up to where the MIS inks are in
terms of fade resistance.

The Lascaux and Premier Art spray cans also seem to have about the best
nozzles I've found, which is important for even results on glossy paper.  Be
sure, of course, to turn the can upside down and clear the nozzle after the
spraying is done to be sure that nozzle stays in good condition.
Additionally, for important prints on glossy paper I avoid nearly empty
cans.  The pressure gets too low to get a good spray.
