ABSTRACT:
To form a good perforation image and prevent oozing of the ink in the processing of plate making, a heat sensitive stencil 10 is generally made of a heat sensitive film 12, a non-woven fabric 16 impregnated with ink, a separator 14, a frame 18 located so as to surround the non-woven fabric 16, and a film 20 as a base having an ink impermeability. The separator 14 is located between the heat sensitive film 12 and the non-woven fabric 16. An end portion of the separator 14 is inserted through a slit 18c of the frame 18, and extends through between the frame 18 and the film 20 to the outside of the heat sensitive stencil 10.
