ABSTRACT:
A screen fabric employed in screen printing is improved by flattening its selvages to the extent of the thickness of the ground of the screen fabric so that wrinkles having been occurred in the selvages of the wound-up fabric are removed to increase the yield of stencils obtained from the screen fabric. In addition, the thus flattened selvages make it possible to apply a sufficiently large tensile force to the screen fabric in its stretching operation in order to produce a highly precise stencil for conducting a precise screen printing of the circuitboard and the like.
