Stencil sheet roll and a method for preparing the same
 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.
