My company is looking to start producing ADA/way-finding signage via the photopolymer process. We have in the past been using a Roland Desktop engraver. I have looked into the photopolymer process and like the way it works. Can anybody who has had experience with using photopolymers for ADA compliant tactile and braille signage weigh in on it. Is it worth the investment? We have spoken with Nova Polymers, are there any other companies that offer similar equipment? Any direction and or advise would be greatly appreciated.
