FREMGANGSMAADE OG STENCILARK TIL FREMSTILLING AF EN DUPLIKERINGSSTENCIL

摘要

A duplicating stencil is produced by placing an electrostatically-produced image on a substrate in contact with an ink-impervious surface layer of a stencil blank, bonding the image to the surface layer by the application of heat and/or pressure and stripping the substrate from the stencil blank to remove the surface layer in the image area. The surface layer may comprise a synthetic resin composition containing a finely dispersed pigment and is attached to the porous base tissue of the stencil blank by an adhesive. Bonding of the image to the surface layer and possibly also fixing of the image to the substrate in the same operation can be effected by means of infra-red heating.
