No toners or inks used in inkjets are totally lightfast. Even the best have
lives measured in 5 years or so. To get permanence in computer printers you
need dye-sub, or the dye-sub mode in the ALPS printers, and even then the
litefastness is perhaps 20 yrs or so. There is a Web site (I don't have the
reference at hand, but you can use one of the search engines to find it)
that provides full details on expected life of all these inks. One of the
great factoids about most alt processes is the long lifespan of the images
that are created, lifespans measured in centuries, not years!
