摘要： The present invention provides a stencil sheet roll formed by winding up a stencil sheet to form a roll, the sheet including a thermoplastic resin film and a porous support laminated thereto, wherein the compression elastic modulus of the sheet is not less than 32 kg/cm.sup.2. The invention also provides a stencil sheet roll formed by winding up a stencil sheet to form a roll, the sheet including a thermoplastic resin film and a porous support laminated thereto and having been subjected to calender treatment. Also disclosed is a method for manufacturing a stencil sheet roll comprising laminating a thermoplastic resin film to a porous support to form a stencil sheet, subjecting the stencil sheet to calender treatment, and winding up the calender-treated stencil sheet to form a roll. According to the present invention, excellent printing images can be obtained since compression elastic modulus of a stencil sheet is enhanced without impeding permeability of ink and thus deterioration in quality of images due to reduction in surface smoothness of the stencil sheet can be effectively prevented.
摘要翻译： 本发明提供一种通过卷绕蜡纸来形成辊而形成的蜡纸卷，该片包括热塑性树脂膜和层压在其上的多孔载体，其中片材的压缩弹性模量不小于32kg / cm 2 。 本发明还提供一种通过卷绕蜡纸来形成辊而形成的蜡纸卷，该片包括热塑性树脂膜和层压在其上的多孔载体，并经过压延处理。 还公开了一种用于制造蜡纸卷的方法，其包括将热塑性树脂膜层压到多孔载体上以形成蜡纸，使蜡纸经受压光处理，以及卷起压延处理的蜡纸以形成卷。 根据本发明，可以获得优异的印刷图像，因为在不妨碍油墨的渗透性的情况下增加了蜡纸的压缩弹性模量，并且因此可以有效地防止由于模板的表面平滑度的降低导致的图像质量下降。
