~I've tried gumoil. It is not an easy technique to master. Itis very
different from gum bichromate printing. First it uses an enlarged positive
rather than an enlarged negative and uses oil paint rather than water color
pigment. The effect is rather dramatic and high contrast. If you like
Kodalith type images you will like gumoil. Making a monochromatic image is
rather simple , the trick is doing the "bleach/etch" step. I was never able
to see the change in the gum in the bleach bath nor was I am be use a water
spray to remove the loosened gum. It always took a brush to remove the gum.
The process was very difficult to control and the images all had a
posterized look to them. Not what I was interested in.
