A stencil printer of the present invention includes a master making section for perforating a master, which includes a porous support and a thermoplastic resin film, in accordance with image data to thereby make a master and wraps the master around a print drum to thereby effect printing. The stencil printer includes a cavity sensor for sensing the condition of cavities existing in the porous support of the stencil. A controller identifies the kind of the stencil by determining the condition of the cavities in accordance with information output from the cavity sensor, so that stable print quality is insured without regard to a difference in cavity ratio between the lots of stencils.
