Abstract: A microporous stencil sheet for use in stencil printing and methods for making stencil master using this microporous stencil sheet are disclosed herein. The microporous stencil sheet is for use in stencil printing using a low-viscosity ink with a viscosity ranging from 0.001 to 1 Pa·s, comprises an inelastic resin film and has an air permeability ranging from 1 to 600 seconds and a thickness ranging from 1 to 100 &mgr;m. The methods for making stencil master using this microporous stencil sheet comprise the step of closing the micropores of the stencil sheet in a non-printing portion of a desired printed image.
