Lumizip 900

The Lumizip 900 was a functional phototypesetter, a type of machine used in the printing industry for photocomposition. Unlike earlier typesetters that used lead, functional phototypesetters created text images directly onto a photosensitive surface using light. The Lumizip 900 represented a significant advancement by minimizing moving parts. Instead of a revolving disk or drum for matrices, it used stationary matrices and a moving lens component. This design allowed it to photograph an entire line of text at once, achieving exceptionally high output speeds of over 2,000,000 characters per hour. This machine required magnetic tape for input and was used to produce works like the Index Medicus.12
