Yves,
I routinely use the 2:1 gum/K dichromate ratio for my gum prints and
still have what I call the dichromate image. I've asked a chemist
colleague investigate whether this image/stain is some form of chromium
or simply discolored/tanned gum arabic, but it will be awhile before the
analysis is completed.
