FWIW.
The life of an inkjet print from a Canon printer is not limited by exposure
to light as much as exposure to the atmosphere itself. One really unique
facet of what happens when you pay someone to "independently" assess print
life is that they only assess the criteria they are paid for. Pretty simple
when you think about it.
The estimated life of a Canon inkjet print is calculated on whatever process
Canon paid Wilhelm to use... Exposure to light. The fact that Canon's dye
inks on ceramic coated photo paper, evaporate off the paper and shift colour
based on the elements in the atmosphere were never considered in the "25
year life" now quoted for their prints. Talk about controversial processes.
Canon's professional dye ink plotters (the really big ones) use laminate to
seal the surface. Not practical for home use.
One simple way to extend the life of Canon prints made on Photo paper is to
laminate them. This probably won't get you 25 years on display - more like a
year or two because Canon issue a warning about their prints which say you
should store them in a dark place, away from light!!! What is a photo for,
then?
If you leave their unprotected prints in the path of an air-conditioned or
exposed to the atmosphere from a kitchen or in a room often filled with
cigar smoke, even exposed to decaying electronics, the life before colour
shift and fade may well be measured in weeks.
There are some in this group who defend the industry's most controversial
life of prints tester. All of them have passed over the fact he is funded by
the very companies we are now discovering are using him to defend their
false advertising claims. If the life of an inkjet print were measured
against the known life of a photographic print, we'd all stop buying inkjet
printers.
