For years I have been telling customers Cibachrome was the only color print the majority of museums would acquire for their collections and the only color print fade resistant and permanent enough to not worry about hanging. Now, my custom lab says because of the shortage of Cibachrome they only want to do Lightjet prints. I must admit the 11X14, 20X20, and 30X40 prints they have recently done look good, but then I do not have a Cibachrome classic to compare them side by side. I am also concerned about the longevity issue. Some input about museum thought would also be of help.
