Hi:
In Barnier's chapter on oil printing in "Coming into focus" he says
hardening is unesseccary for the matrix if a hard gelatin is used. He
recommends three coats of gelatin, hardening if a soft gelatin is used,
and then superdrying the matrix (heating the matrx).
This is supposed to provide a gelatin coating that will swell
apporpriately for inking.
I thought I would try a hard gelatin in order to skip a step :)
