Abstract: This apparatus is a unitary photographic lettering and display typography composing device and has as its objective the creation and mechanical combining of two adjacent master and slave photo typographic systems into one unitary, simultaneously controlled photographic, daylight operating lettering composing device that can produce display headings, captions and sub-heads in either English or foreign languages, on a full sheet of photographic paper. Because of its constantly yellow-illuminated character image that develops into a black character image instantly upon exposure to white light and its visible spacing control, its transverse and longitudinal motion adjustability of the photographic paper, it also lends itself to the composition of Semitic and Oriental languages, border designs, overall background pattern tint effects and engineering symbols.Each character is constantly projected in the master unit from a yellow safety light source and is visually spaced to the desired position.
