There is a very good article on "Predicting the Life of Printed
Images" and why it is almost impossible to pin down. The article is
in the March/April 2003 Photo Techniques. It is by Eric Everett a
tech specialist at Q-Panel Lab Products, a manufacturer of light
stability and weathering test equipment.
