With traditional pigments, the pigment is suspended in a binder, and 
it's this binder which holds the pigment on the substrate.  Change over 
time can happen with any element.  I.e. the substrate can deteriorate, 
the binder can deteriorate, or the pigment can change.  With current 
computerized ink printing, doesn't the coating on the paper act as the 
binder?  Are there any issues with these coatings breaking down over time?
