Digital BW, The Print

Doug,

I have not done a survey of old test strips, but the ones that caught my
attention were some old Piezo on EAM test strips that I wanted to compare
current results to.  I suspect that it affects all of them.  If the process
is oxidation, then even dark stored prints would be expected to "age," even
if at a rate that is much slower than one exposed to light.
