Why? Both sorts of prints are exposed to the same amount of UV as they are pinned to the same fridge.
I wonder if there is a better printing technology comparable to analog "prints" (of film). That would actually make more sense (to me) than saving everything on M-Disc.
Ah, sorry I thought the old ones were stashed somewhere. Yeah, I'd like that too, although not sure who would I trust telling me that these will actually be like this in 30 years.
In the meantime I found out that there are in fact printing technologies based on pigments with a longer lifespan. For instance Epson Surecolor or Canon imagePROGRAF. The alternative is to use online services who produce actual "c-prints" of digital images.
