I have found also that a larger ratio of gum to dichromate makes a
*softer* emulsion... in fact since I reduced the concentration of my
dichromate (from 26% to about 12%) I've never had a layer that couldn't
be brushed off. To make it even softer, increase the ratio of
gum-pigment. That is, instead of equal parts gum & sensitizer, try 1-1/2
or even 2 parts gum to one part sensitizer.
