Robert,

Do you know what kind of carbon is used?  My chemist brother is guessing it
is a graphite.  Assuming that it is, there is a whole specialty on the edge
effects relating to graphite.  Graphite forms itself into plates, where the
surfaces are smooth (thus its lubricating qualities) and rather
non-reactive.  The edges are where the action is.  That is where the
oxidation that is apparently the source of the fading probably takes place.
It might also be where we could find a toner to lock up those open bonds --
just like with silver and selenium.  I think there is a lot to be done with
this technology, but getting accurate information is not very easy.

Tree?  That was a self portrait!  ;-)
