All my tests were very destructive and not meant for a real or normal situation, they had full exposure to all the elements for 24/7, it was to show that it’s pointless to use dye inks in a high UV or ozone environment and expect them not to fade...I was surprised with the results obtained by "The Hat" with the laminated photo.
Which XP model are you testing here ? Pigment inks will improve the fading performance very much, and bronzing can be eliminated by a separate overprint with gloss opimizer with a separate cartridge for the black channel in B/W mode.Anyway, I am now doing experiments with the Epson XP line in order to use pigment ink instead of dye. Bronzing is now the villain.
the typical lamination process works with a glue between the paper and the film, and hot lamination works with heat to activate the glue, it could be that the glue reacts with the ink dyes, or the heat accelerates the process. I assume that your kitchen type film just adheres electrostatically to the paper and you can pull it off easily. There are several effects to consider, does the film filter and block the UV radiation and/or does it provide a barrier against ozone and other chemical agents or both ? And in which ratio ? So there are several variables in the game which may lead to different results depending on the circumstances.
