Digital BW, The Print

I tried coating some Silver Rag (I do hope that they change the name)
with Krystal Topkote in a second pass, The visible improvement was
quite dramatic – possibly the biggest improvement that I've seen
during the short period I've been testing Topkote. The D-Max increase
of around 0.13 was plainly visible, as was the reduction in glare. As
this is beta test paper, it may be that the surface properties of the
paper I'm looking at are not the same as those that everyone else is
looking at. 

Because I only got five sheets in total (hey, I'm grateful that they
sent even five sheets to an obscure nobody like me) I couldn't do a
full side-by-side coated/uncoated test to quantify the density change
at different original densities. As with Epson Premium Glossy Photo,
the only other paper that I have done any significant amount of
Topkote testing on, the coating improved the shadow separation. Coated
EPGP has a slightly higher D-Max than coated Silver Rag, but the
coating narrowed the gap, and these results are, of course, just for
my printer setup and they could change as I tweak the profiles to make
the most of the coating.

When the four Silver Rag postcards that I had sent out were received,
one postcard showed a little scratching/abrasion through to the paper
base. I suspect that the Topkote will protect against that to some
extent. Even uncoated, it is excellent postcard paper.
