Let your gass out

At home I have a whole series of photo frames and from time to time I like to swap the contents of them. One of the things I have noticed is that often when I open the frame a ghost image has appeared on the inside of the glass.

As the image doesn't touch the glass - how does it happen? Well apparently it is caused by solvents in the inks "out gassing". I came across this article that explains why this fogging occurs and how to stop it.

In a nutshell Epson recommend:

1. After printing, let the print rest for 15 minutes.
2. After 15 minutes, place a sheet of plain paper (not photo paper) on top of the print and let
dry for 24 hours. The paper acts like a sponge to absorb the gasses and accelerate the
outgassing. (You may stack the prints if you are printing more than one. Be sure to
interleave each print with a sheet of plain paper.)
3. After 24 hours, remove the plain paper. You may notice the plain paper is wavy. If it is,
repeat the procedure again with a new sheet of paper for another 24 hours, after which the
print should be ready for framing. If it is not wavy, this indicates that the solvents in the
print should now be completely dry and the print should be ready for framing

I'll have to try this and see how it goes.
