They discolor and disintegrate over time. Inkjet papers are composed of a backing layer and an inkjet receptor coating.

Inkjet prints are subject to damage by water, light, atmospheric contaminants and framing materials.For longevity tests not sponsored by printer manufacturers, see the Light Fade Test Results at Aardenburg Imaging. Typical longevity testing is performed under controlled humidity and lighting conditions that are rarely encountered in the real world (read this report from Wilhelm Imaging).Every combination of printer, surface and ink has its own fading profile: each color fades and shifts at its own rate.There is no official standard for 'noticeable'. Experts define image permanence with regard to how long it takes for colors to fade and shift by a 'noticeable' percentage.Galleries and photographers who sell them (and the companies who sell printers, paper and ink) may be reluctant to emphasize this point but ironically, the best way to preserve inkjet prints is to store them in total darkness at low temperature and humidity.Images printed onto metal and glass are also subject to fading and discoloration. Like the countless millions of Kodak and Fuji prints produced over the decades, inkjet images start to fade and shift as soon as they roll off the printer.
