摘要

Method to produce a printing stencil (10) for the decoration, by writings and/or images, of printing supports, on which ink and/or glaze is able to be applied, able to transfer the writings and/or images onto the printing supports by contact with the printing supports. The method comprises at least a stencil molding step in which at least a first image transfer layer (11), provided with a printing surface (11a) and comprising gelatin and/or photo-engravable emulsion, at least a second support layer (12), comprising a silk-screen fabric or suchlike, and at least a third anti-leakage layer (13), comprising a polymerizing film and able to prevent the leakage of the ink and/or the glaze, are associated with each other so as to form a single multi-layered photo-engravable element, which constitutes the basic body of the stencil (10).
