Tim, Paul recently told me something about the uniqueness of their
molecular structure... er somethin'... it went right over my head.
It is apparently different, and of course you are right about
historical carbon prints.
I'm still unconvinced the existance of material in addition to carbon
has any detrimental effect on an ink's longevity. This carbon thing is
becoming mythical, there's little to support it.
Inks have lots of things going on in them besides ingredients to make
density, and/or color, and I suspect some of those things effect fading.

As a pure element, yes, carbon makes diamonds, bla bla... and the
historical carbon processes were very stable.
But when it comes to carbon and inkjet ink, it's kind of like saying
Tang is made from oranges.

I don't know, that's what I'm thinkin'.
On the other hand, there are a lot of fine art B&W lightjets out there
made on Crystal Archive, those will surely change color. I'd say the
concern at the buyer/dealer level is conversely porportional to the
fame of the artist. Did anyone ask how long their Hockney Iris would
last before they took out a loan to buy it?
Little of this stuff is based in rationality.
