Process for producing a base mold for electrolytically producing seamless rotary screen printing stencils

A process for producing a mold for electrolytically producing seamless rotary screen printing stencils, the process comprising the following steps:

• providing a metal mold body having a cylindrical outer surface;
• covering the outer surface of the metal mold body with a sensitive layer selected from the group consisting of a photo-sensitive layer, a thermo-sensitive layer and an electrically sensitive layer;
• exposing predetermined portions of the sensitive layer to a beam which is controlled electronically by a controller having a memory with a grid stored therein, thereby creating exposed portions of the sensitive layer as well as leaving unexposed portions of the sensitive layer;
• removing the unexposed portions of the sensitive layer by a process selected from the group consisting of physically removing the unexposed portions and chemically removing the unexposed portions;
• generating indentations in the metal mold body at predetermined areas where the unexposed portions have been removed by a process selected from the group consisting of etching and electrolytical metal removing;
• removing the exposed portions of the sensitive layer;
• and
• filling the indentations with a non-conductive filler.
