Re: OT inkjet neg fading

If you're running a humidifier AND a de-humidifier you may be preserving the precious water supply while increasing global warming... Look out your window: that's me with the 'Save the dinosaurs!' sign.

  Mark & Others,

  I don't know if anyone has mentioned this, but much of this information is available from Wilhelm Imaging Research. Henry Wilhelm is recognised as "the expert" in this area of image permanence. They have a PDF you can download for free, but be forewarned, it is 80 megabytes in size!

  I have a friend who bought a print she just loved from a local artist. The artist had made the print on nice watercolor paper and then did some very nice work with pastels on top of it. In about 3 months, my friend came over storming mad and showed me her $300 print—all that was left was the pastels and a very very faint vision of the original inkjet—which was dye based.

  Anyway, check out the Wilhelm site, it is interesting.

  Alt Photo Tip for Winter: If you live in the northern zones and are finding printing is difficult due to low humidity and have to run a humidifier, you can conserve our precious water supply by also running a dehumidifier.

    To answer Judy's question, no, I never thought that inkjet prints were
    archival. But what surprised me was how rapidly the print loses
    density. In the article I mentioned, they had a graph that showed print
    density loss versus time. By 70 days, there was a 0.12 loss of print
    density, or almost a third of a stop. I am well aware that this was a
    specific result that is applicable to one printer/ink/paper
    combination, but it sure gives one pause. My post was really just to
    see if anyone has noticed any density loss with their inkjet negs over
    time. I suspect that the dye based inkjet negs will show some loss,
    whereas the pigment based inks that I'm guessing that Sandy uses on his
    2200 will show much less of a loss over time.
