Digital BW, The Print

I'm not so sure any more.  I always reserve the right to change my mind.

After the last test, I'd have to say that Lascaux (B72) is good for some
physical protection, but it did not help at all with respect to
lightfastness.  In the past it had no effect on this issue.  This time it
looked like it might actually lower the lightfastness slightly.  (This could
be a random error it was so small.  However, it was enough to raise a yellow
caution flag in my mind.)

I do think that matte prints need some physical protection.  Putting them
under glass is great, but who wants to do this with most shots?  So, among
the other ways to protect the image somewhat, B72 seemed like a relatively
good way to go.  It *was* neutral in lightfastness, has a great reputation
in the conservation field, has about the least effect on dmax (matte dmax
often decreases with light sprays), and is easy to use.

Bottom line, it is probably a good idea if the print is otherwise
unprotected.  However, we really need a better spray for matte prints.  I
have not tested many papers, but PremierArt (which increased lightfastness
in the last test and is great on glossy paper) lowers the dmax unacceptably
on some matte paper.  So, be sure to test a small test strip before using it
or any other spray.
