Read the printer's manufacturer report on photo testing (usually found on the box) when selecting which printer to use. Every manufacturer does in-house and/or independent testing to determine how many years their inkjet photos are likely to last. Although there are inconsistencies in how these tests are performed, it does give you a basic method of comparing inkjet printers for printing photos that last.
Use high-quality photo paper made by the manufacturer of your printer. For example, if you have an HP printer, use HP photo paper.
Display the photos in a glass frame or acid-free photo album. In a study presented at the Imaging Conference Japan 2007, photos kept in glass frames had significantly less fading due to less ozone exposure. Photo albums with plastic sleeves will also protect photos from ozone.
Do not hang or display your photos where they will receive direct sunlight through a window. Direct light will accelerate the fading process.
