Pho′to-type.
（Photography.) A general term for processes in which sun-pictures, or light-pictures, as the name indicates, are made printing-surfaces and thus become the means of multiplying pictures. The term has been specially applied to the following process: — An impression on a plate in raised characters derived from a transfer obtained by the photozincographic process. The original manuscript or page of type is photographed, treated with ink, washed and transferred to the plate, which is then bit in, so as to depress the surface at points not protected by the ink. (See photozincography.) For an analogous process, see Photoglyphic engraving. The resulting plate has a salient impression, and is printed from as with ordinary type.
