There are many types of photopolymers. Rubber stamps are made of much
softer PP than letterpress plates, so I assume there are quite a
number of different types.
I have a friend who makes rubber stamps using a liquid photopolymer
on a machine called a Merigraph. It was poured between two glass
plates in contact with a negative, then exposed top and bottom,
washed out and reexpoed. She also had a harder setting liquid that
made a couple of photopolymer plates for me in the past, though they
were somewhat less precise than the ready-to-expose materials common
