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

Hello,Michel,
your interesting morsel about the Foxlee process once again, well stocks
our larder, I have not heard of or read of such a process so the reward is
even greater.
However, the principle of separating the colourant from the colloid ,was a
concern of mine in experimental research a few years ago, and in theory has
much to recommend it.
The method was to expose a plain gum/gloy emulsion
containing no pigment ,then roll over with greasy ink,process after soaking
in water when if all has gone well the ink should come away with the
unexposed gum, another variation was to use acrylic in the same manner, the
acrylic was sprayed on.the problem with this method is that a
photo-mechanical image is needed such as halftone or random screen to
render tonality,a variation of this technique which did give a satisfactory
indication that it might work if I had devoted more time to was a wet in
wet technique similar to the painters methodology.
A sheet of paper was roller coated with a a wet coat of sensitised gum/gloy
, not dried, then sprayed with acrylic, this gave a good tonal image
without the need
for photo-mechanical tonal reproduction .
Hope this may be is of interest,
pete
