Re: [Digital BW] condensation from print

Classic outgassing description. If you had framed it under glass, this film would now be on the inner surface of the glass, and you would need to open the frame to clean it. Most of the outgassing occurs in the first day or so, but it continues at lower levels for some time.

In December I printed a few 16x20 colour images on canvas. I used an Epson 4880 with all Epson colours and MIS blacks.

One of the prints was off a bit from the colour balance I wanted, so I set it aside in my darkroom, draped face down over a 35mm Saunder 4500 negative carrier that was on top of a few boxes of 8x10 paper. I did not disturb it until yesterday, at which point I saw what looked like mildly viscous patches on the black surface of the negative carrier. They looked a bit like oil or glycerol. These deposits were not there when I set the print on the carrier. The patches cleaned off easily with Windex.

Does anyone know what the substance was? I was surprised that it had apparently moved from the ink to the metal carrier, and even more surprised that it still there four months after the print “dried”.
