The acid free rag papers, even the coated ones, are going to last a long
while. It all depends on the inkset and its behaviour with that particular
paper. If you are printing pigment inks (eg the Coneset) on acid free rag
paper, your prints are going to be around for a long time. Lysonic inks on
Luminos paper are tested for >120 years longevity.

There will probably be some slight shift of tone and maybe a lowering of
Dmax, but these processes are potentially at least as archival as normal
fine art printmaking methods. There is no absolute in archival, and there is
almost always in *any* method a compromise to be negotiated between absolute
print quality and permanence. Few great paintings by the old masters would
be considered 'archival' in the sense we talk about inkjet prints!

There is an interesting article by Jon Cone at:

The wilhelm research data on inkjet longevity can be found at:

...although it should be noted that Wilhelm's research does not address the
ozone-fading problem that undermined the 1270 longevity claims.

Bottom line: pigmented inks on archival paper!
