ABSTRACT:
In the thermal stencil master plate and the method for processing the stencil master plate according to the present invention, since swelled and solidified unprocessed regions formed by film lumps or a part thereof produced from the melted film are provided continuously, the merging and excessive expansion of the perforations can be avoided so that clear printed picture images may be formed even in the regions of solid picture images. Further, the ink passing through each of the perforated dots is reliably separated from the ink passing through adjacent perforation dots before it is deposited onto the printing paper so that excessive deposition of the ink is avoided and the time required for drying the printing ink is reduced so that offsetting may be avoided.
