Photon-Lumitype 713
Quick Summary
The Photon-Lumitype 713 was a functional phototypesetter introduced in 1957. This machine was part of the second generation of phototypesetters, which aimed to minimize mechanical parts and friction.12
The Photon-Lumitype 713 operated by exposing photosensitive material to light through transparent letter matrices. It could produce between 70,000 and 80,000 characters per hour. However, this speed was nearing the limit for techniques using a rotating matrix case due to centrifugal force. These machines represented a significant advancement in printing technology, moving away from traditional lead-based typesetting towards photographic methods for composition.12
