Various A4 colour photos we have stuck onto the bedroom walls for 1 or
two
years have noticeably faded. Is this expected? They were printed using
Hewlett Packard printer, HP ink and photo quality paper.
Fade can be "normal", but it depends on a number of factors, including
ink and paper and exposure. HP's recent models with Vivera ink have
much better fade resistance than previous models. The inks used in the
#97/99 cartridges have 2-5x better fade resistance than those used in
the 57/58 or 78 cartridges, which have 2x or so better fade resistance
than the 41 or 23 cartridges. Paper can make a very large difference;
inks rated for over 100 years fade resistance on some papers may have 1
year on different papers. For comprehensive data take a look at Henry
Wilhelm's web site. He has a few hundred articles on fade resistance
based on decades of research. See

subject you can download Henry's 758 page book on the subject of "The
Permanence and Care of Color Photographs: Traditional and Digital Color
Prints, Color Negatives, Slides, and Motion Pictures", a free download.
If you specify what ink and paper you are using and the display
conditions (covered, open to air, exposed to sunlight, etc) someone here
could probably give you more specific suggestions.
