After a color-expert columnist suggested we really didn’t yet know what the archival quality of ink jet prints would be, I decided to do my own experiment.
Two years ago almost to this day, I printed out digital images of two paintings of mine, covered portions of them with several layers of opaque artist’s tape, and left them on the sunniest, south-facing windowsill in my house. There they sat undisturbed for a l-o-n-g time.
Results below. The one printed on glossy photo paper (Easter Island, WA) shows no visible signs of fading or discoloration at all. I can’t even tell where I put the tape. However, the one I printed on good-quality bright white office grade paper(Cleared Trail) faded and discolored badly — particularly all the warm colors.
