I think that accelerated aging only tests for a narrow set of conditions
and not the real world hazards that actual prints are subject to. We
know how silver halide prints survive over time from the millions that
have already done so. Inkjet prints are more fragile due to the nature
of their coatings and in the very thin amount of ink on the surface.
They scratch easily. More research needs to be done in this area.
As opposed to Wilhelm, I think Aardenburg may have a far more realistic
way of testing for a predictable useful life of a print. Mark has done
some good work.

Hi John.
You get a sense that the Wilhelm longevity tests are off in their
estimates?
What happened that made you come to these conclusions? Was one or more
of
those estimates proven incorrect based on your own observations?
