Digital BW, The Print

In our coatings study, the dmax of uncoated 100% Piezo Black printed on
Orwell dropped from 1.69 to 1.53 in 6 weeks of full LA sun.  I don't know
how to convert this to stops...maybe Antonis could help with this one.
Regardless these were really harsh conditions.  I doubt a silver print would
have done as well...but I don't have 21 step wedges of silver prints to fade
side by side...wish I did.
