    摘要： A process for perforating a stencil sheet comprising a thermoplastic resin film is disclosed which process comprises melting predetermined portions of the thermoplastic resim film with the heat from heat-generating elements to form perforations while applying a pressure to the film and under such a condition that the film is spaced away from the heat-generating elements by a close distance. According to the process of the invention, perforations through which ink passes smoothly can be formed in a stencil sheet using a thermal head and thus clear images can be obtained.
