ABSTRACT:
The invention relates a source sheet for stencil printing comprising: a porous support material; a porous resin film formed on a surface of the porous support material;wherein, the porous support material has a maximum air permeability of 90 s/100 cc; and,the porous resin film has a maximum air permeability of 600 s/100 cc;preferably, the air permeability of the porous support material≦the air permeability of the porous resin film.According to the source sheet and plate manufacturing method of the present invention, the plate for the stencil printing can be obtained which is superior in the pore block property and in which the thermal deformation of the source sheet during the plate manufacturing is suppressed.
