There is a problem that it is difficult. Further, in order to form a high-resolution, clear print image, for example, the stencil portion of the stencil image formed on the thermoplastic resin film layer constituting the copy printing plate must be 3
From 500 dpi (dot per inch) to 500-600d
Pi has been tried, but in the case of a stencil image in which such fine perforations are formed, the above-mentioned problems become even more remarkable and undesirable. Therefore, the present invention provides a transcript printing method in which a porous support layer or an adhesive layer does not block a perforated portion of a stencil image formed in a thermoplastic resin film layer constituting the transcript printing plate. The object of the present invention is to provide a heat-sensitive stencil sheet capable of forming a high-resolution, clear printed image, and a stencil printing plate using the same, in which the ink is transferred to a printing substrate such as paper in a sufficiently satisfactory state. It is assumed that.

In the present invention, if the support layer can be peeled off and removed from the partial adhesive layer after plate making as described above, this is sufficient, but the adhesive strength of the partial adhesive layer is strong. When the support layer is difficult to remove and remove, the support layer in the vicinity of the partial adhesive layer above, after forming a stencil image on the thermoplastic resin film layer constituting the heat-sensitive copying base paper, or Before that, the support layer constituting the heat-sensitive stencil sheet is cut off from the heat-sensitive stencil sheet, and a cut-off line for separation which can be removed can be engraved to manufacture the stencil printing plate according to the present invention.

In the above description, a method of engraving a cut line for separating the support layer on the support layer near the partial adhesive layer will be described. There are various methods, such as heating. It can be performed by a method such as a needle punching method for pressing a needle, a physical perforation method using a knife or a cutter, a laser beam irradiation, a processing method such as a corona discharge or a plasma discharge, or the like.

When a heat-generating element is brought into contact with a thermoplastic resin film layer constituting the heat-sensitive copying base paper, a heat-sealing prevention layer is passed through, and a character, a pattern, or the like is subjected to heat-sensitive printing to make a perforated plate to form a stencil image. In addition, a material having a heat insulating property for shutting off heat from a heat generating element such as a thermal head or the like can be used. For example, various kinds of paper, particularly open paper such as Japanese paper, rayon , Vinylon, polyester, acrylonitrile, tissue paper made of chemical fibers such as polyamide, the above-mentioned chemical fibers,
