Using old color paper is a nightmare to print with, especially if you don't know how it was stored. There is no consistency due to all different color shifts so you can't count on your usual color filtration settings and exposure times. It's OK if you want to spend the time taking 3-4 attempts at making a print, which you'll end up doing to account for the paper color shifts. About 10 years ago I got 6 boxes of old Kodak color paper for just the postage and ended up throwing it all out in frustration. I've used 3 year old Fuji Crystal Archive paper that I bought fresh and stored as recommended (50F or below).
