Digital BW, The Print

I think there may be potential in having different materials and dual or
multi-coating of papers.  However, on the matte papers you're liable to
start to lose dmax after 3 light Lascaux sprays.

The Lascaux is a thinner mix that soaks in more.  So, I'd think that might
go on first.  Then the heavier UV that lays on top.  A Lascaux-like spray
that had a UV filter in it might be useful if we could find one.    

This multi-spraying might be particularly effective when the top coats are
the Eco Print Shield or other water-borne coating.  I found, for example,
when I was experimenting with Hydrocote that if the print was sprayed first
with Lascaux I got less if any separation at the edge when I trimmed the
print.

Livick's very high lightfastness used a dual coating method very similar to
this.

The Golden tech told me that the solvent based UV coatings are more
effective than water-borne.  On the other hand, the Eco Print Shield appears
to be more effective in fade testing.  I'd guess it is the thickness, not
the effectiveness per mil.  This might indicate that a UV solvent based coat
under the Eco water-borne would be even more effective.

Anyway, dual or multi-layered coats might have potential.
