Abstract (en)
[origin: WO2013030273A1] The present invention relates to a method for producing a printing stencil for technical printing, for applying a printed pattern to a substrate, and to a printing stencil. The method comprises supplying a carrier layer (21) for the printing stencil, supplying a structure layer (22) for the printing stencil, this layer being located beneath the carrier layer (21), making an elongate printed-image opening (22a), corresponding to at least part of the printed pattern, in the structure layer (22), and making carrier-layer openings (21a) in the carrier layer (21) in the region of the printed-image opening (22a). The method is characterized in that, for making the carrier-layer openings (21a), use is made of a laser device which is designed to emit a laser beam in laser pulses, and the task of making the carrier-layer openings (21) comprises making a row of carrier-layer openings (21a) extending in the longitudinal direction of the printed-image opening, wherein, for making each carrier-layer opening (21) in the row, a focussing means of the laser device is positioned at a position of the respective carrier-layer opening (21), and the respective carrier-layer opening (21) is made by means of one or more laser pulses at this position (P1), and the focussing means of the laser device, once a carrier-layer opening has been made, between two successive laser pulses, is displaced relative to the carrier layer, and in the longitudinal direction of the elongate printed-image opening (22a), from the position (P1) of the carrier-layer opening (21a) which has been made to the position (P2) of the carrier-layer opening which is subsequently to be made.
