Abstract
A heat-sensitive stencil including a porous support, and a thermoplastic resin film laminated on the support and having a surface smoothness of at least 10,000 seconds. The stencil is fabricated by bonding a thermoplastic resin film to a porous support with an adhesive having a specific viscosity and a specific volatile matter content, while maintaining each of the support and the film under a specific tension. The stencil may also be fabricated by applying a coating composition containing a resin and first and second solvents having a specific solubility and specific evaporation rates, and drying the applied composition to form a porous support. A printing master is produced by heating the above stencil imagewise by a thermal head with a heating energy of not greater than 0.05 mJ/dot.
