RE: [PPLetterpress] plate specifications

Thank you for answering my question. It has been indeed helpful. I managed to find a company that sells the plates based on a hardness of 67. However it’s only ex stock, and they aren’t bringing it in again. I am buying up all 40 plates to start off with. Hopefully enough to last me during my learning phase.
Another question. I went to check out two machines today. One of then had a darker red ball, while the second machine which is attached had a much brighter one, I wonder if there is any difference between the two machines.

I understand that you are from Singapore . The soft photopolymer plates you are refering to are flexographic plates such as Cyrel from DuPont or liquid photopolymers for rubber stamps. Flexographic plates have a Shore A durometer hardness of 25-55 versus durometer readings in excess of 60 for letterpress plastic plates. For the history of letterpress photopolymer plates see

Manufacturers of letterpress photopolymer plates include Toray, TOK, Toyobo and Flint Group. Their tradenames are Torelief, Miraclon & Rigilon, Printight and nyloprint resp.
