Has anyone tried using some sensitisers other than dichromate for gum or
carbon? Silkscreen emulsions have used diazo since the 70's. Can it be used
for our purposes? If so, would it be less toxic, and would longevity of the
emulsion be increased?

A somewhat related question: does anyone know the chemical make-up of
KwikPrint? It was popular in the 70's to the 80's. First made for proofing
print jobs and them sold by Light Impressions for alt printing. Best results
when used on a king of vinyl that comes with it. Are there no old timers on
the list who can shed light on it? Seems that it was akin to casein and used
diazo as well.
