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.
Right, Mark has the better method and the institute is more transparent
in its structure. That said he could use more members to continue the job.

True, the inkjet surface needs better protection and a paper integrated
solution has been neglected too long already. On the other hand a B&W
silver halide print that survived without changes on the paper white
(development stains or plain yellowing), RC cracking or layer release
and even changes to the silver composition, must be an indication that
it came from a good lab and better than average archiving after that.
While color pigment inkjet prints share the same surface vulnerability
it is quite clear that they show much better fade resistance than any
chromogenic color process used in the past.
