I have a collection of digital photos which I printed in 2004 from an Epson Stylus Photo 870 onto Epson Premium Glossy Photo Paper. Certain areas of several of these photos now seem very blurry compared to how I remember them - its as if the inks have soaked into the paper / each other more, reducing sharpness. They are all stored in a large folder with plastic sleeves, so they have enough protection. Do digital inkjet prints have a very limited lifespan? I have a large collection of photos printed post-2004 which don't seem to show any signs of aging yet - considering the cost of developing them, I hope they won't!
