A method of and apparatus for reproducing a graphic representation includes a scanner for scanning the original along a series of contiguous lines and transmitting an analog signal proportional to the intensity of the scanned area to an analog to digital convertor to provide a series of parallel, binary signals. Circuitry is provided which permits the digital signals to be stored and retrieved as a number of simultaneous signals from corresponding points in an equal number of transverse bands across the original. The retrieved digital signals are then used to control a bank of drop projectors, equal in number to the transverse bands, which project drops toward a receiving member mounted on a rotating cylinder, with the drop generators moving incrementally, axially of the cylinder, one line spacing each revolution of the cylinder to cause the reproduction to be produced as a series of contiguous, transverse bands corresponding to the transverse bands of the original.
