archival pigment?

In a local office building, the walls are decorated with a typical corporate
art display. There's a set of prints, mostly landscapes, rather fuzzy,
unfocused, like impressionist paintings. The labels read "Archival pigment
ink photograph"

What does that mean?

Hi.
It means the prints were made using a printer like an Epson inkjet
printer using archival pigments as opposed to more tradtional inks.
