Books printed on "good old paper" can last hundreds of years. Don't see the need for "special paper". We have a similar thread about types of ink. Same thing again. Any normal ink is fine. Books that monks wrote 1500 years ago are still perfectly legible. I don't think hi-tech solutions are needed for paper/ink when doing paper wallets. Maybe don't use invisible ink though
Do they? Most books I have start to yellow pretty quickly even after a few years. And those old books are usually written on papyrus or hemp paper or some other form.
I have books from primary school from 30+ years ago, and they are fine. Cheap shit paper and cheap shit ink. What are you doing to make yours turn yellow after a few years? I think that is fungus
Maybe glossy paper ones will last, but not standard paperback books etc. And why are you keeping on to outdated textbooks from 30 years ago? Do they tell you that earth is flat in them?
Nah, just my school reports really, to give my son a giggle "Has potential but doesn't listen" etc. Still in pristine condition after 30 years. But yeah I agree, standard paperbacks use shitty paper, the cheapest of the cheapest, and do tend to turn yellow. Uggh!
