Machines that make copies of print originals by scanning an image, or receiving a digital signal from a computer, and burning a 'master' or stencil onto a photosensitive polyester resin film bonded to thin fibrous paper, which is mounted on an ink drum, through which ink passes onto a paper support. For machines that make a similar type of print from a manually created stencil, and that do not have the scanning stage, use 'duplicators'. For similar machines that use a specific type of chemistry and ink combination, and that are manually operated, use 'mimeographs.'
