They can afford to be smug, can’t they, they’re the ones charging the higher prices for their inks, and as for longevity, they say 100 years in albums with their inks. Huh !'Exceptional results that last a lifetime thanks to genuine Canon ink'
Why should got papers disintegrate in that time. My oldest family photos are from the late 19th century and a lot from the first 20 years of the 20th century. They are now over 100 years old and for sure have not been stored in archival environments. My oldest prints out of the dark room, whether paper or first multigrade papers with plastics are more than 45 years old and no degradations visible.They say 100 years, ? but I reckon the photo paper itself would disintegrate in that time..
about everybody has similar material in his cabinet, it can be the coating of inkjet papers which makes a difference - a mix of organic - binder etc - and anorganic materials - and not so much the base paper itself. Optical brighteners can yellow the coating, and there is a reason that paper companies have a separate line of museum/archival papers for some reason - claiming that they last longer than their regular papers - for some reason. Books have been written about the proper storage of prints and images - not just by Henry WilhelmSo my conclusion is, that long storage times are possible
