A photomechanical print made directly from a hardened film of
gelatin or other colloid; also, the process of making such
prints. According to one method, the film is sensitized with
potassium dichromate and exposed to light under a reversed
negative. After the dichromate has been washed out, the film
is soaked in glycerin and water. As this treatment causes
swelling in those parts of the film which have been acted on
by light, a plate results from which impressions can be taken
with prepared ink. The albertype, phototype, and heliotype
are collotypes.
