Abstract:
1. A stencil printing apparatus having a platemaking device that creates perforations in a stencil base sheet via platemaking means, a rotationally-driven cylindrical plate cylinder on an outer circumferential surface of which a stencil base sheet made by platemaking is mounted, a sheet-feed device for separately feeding out a printing sheet, a printing-pressure device for pressing a fed printing sheet onto the outer circumferential surface of the plate cylinder, and a sheet discharge device for conveying and discharging a printed sheet, the stencil printing apparatus, comprising: wherein the sheet-type detecting unit detects whether the printing sheet set in the sheet-feed device is a coated sheet or a non-coated sheet based on an optical reflectance of the printing sheet, and wherein a film thickness of the coated sheet as a printing sheet is larger than a film thickness of the non-coated sheet, and an adhesive of the coated sheet is stronger than an adhesive of the non-coated sheet.
