Well, the procedure is the following one:
1. Papers must ALWAYS be sized with gelatine, starch or arrow-root =
solution.
2. When they are dried, they are soaked for 2 minutes in a solution of
potassium bichromate and then dried again.
3. They are expose.
4. They are developed like usual (water bath, etc.) and then dried.
5. Then they are coated with a solution of Gum, Citric acid, Glycerine =
and
pigments and dried again.
6. They are soaked in cold water and dried.
As the active dichromate is washed out before the pigment is applied, the end
result would appear to be a lithgraphic variation with the pigment taking on the
tanned size. As such it may give an interesting result but without the
flexibility of the process where the gum and pigmented mixture is dichromated. I
am reminded of the contemporary 'dusting' processes.
I would be interested to hear of results but it does not inspire me to devote
obsessive concern to its further development.

Well, the process is quite long but it is written that one of the main
adavantage of this process is that the concentration of pigment in the
gum solution is not strickly limited since the light has not to pass =
through
a layer containing pigments.
Has anyone tried this process? Judy? Luis?
