So, this may be the issue. Perhaps the correct answer is that if you use dye inks, expose prints for protracted periods to either direct sunlight or fluorescent lights and don't use UV glass, you may get deterioration within a few years.
I know that good pigment inks last many decades under good conditions. I don't recall reading what happens to them if exposed to UV.
