Thanks Tom for the quote from "Studio Colotype". I have been looking
for that book but it isn't in local libraries. It's price is a little
too dear for me to buy.

Phritz, The colotypie site appears to me to show the gelatin being
applied in a thin coating that is brushed out with a hake brush
allowing excesses to flow off the sides. It would seem that casting a
thick layer like carbon printing would lead to excessive topography on
the plate with the hardened areas being lower than the unhardened
areas. That would (I think) make printing details difficult. It would
appear that a thin coat would be better. These is just an intuitive
surmise.
