The system is heavily based on [[hot metal typesetting]] technology, with the metal casting machinery replaced with photographic film, a light system and glass pictures of characters.]]
In 1949 the Photon Corporation in Cambridge, Massachusetts, developed equipment based on the [[Lumitype]] of [[Rene Higonnet]] and [[Louis Moyroud]].<ref>{{Cite web |title=René Higonnet {{!}} French printer {{!}} Britannica |url=https://www.britannica.com/biography/Rene-Higonnet |access-date=2022-12-30 |website=www.britannica.com |language=en}}</ref> The Lumitype-Photon was first used to set a complete published book in 1953, and for newspaper work in 1954.<ref>[http://www.prepressure.com/prepress/history/events-1950-1959 Prepressure – the history of prepress & publishing, 1950–1959], retrieved on 8 May 2014</ref> [[Mergenthaler Linotype Company|Mergenthaler]] produced the Linofilm using a different design, and [[Monotype Corporation|Monotype]] produced Monophoto. Other companies followed with products that included [[Alphatype]] and Varityper.

To provide much greater speeds, the Photon Corporation produced the ZIP 200 machine for the MEDLARS project of the National Library of Medicine and Mergenthaler produced the Linotron. The ZIP 200 could produce text at 600 characters per second using high-speed flashes behind plates with images of the characters to be printed. Each character had a separate xenon flash constantly ready to fire. A separate system of optics positioned the image on the page.<ref>Harold E.
