Abstract A method and apparatus for producing a silk screen matrix wherein a master, having contrasting characters scribed thereon that are to be reproduced is scanned by an electronic scanning device. The scanning device converts light or dark images on the master to electronic impulses. These impulses are transmitted to a punching apparatus, where they are used to activate a punch, which may be pneumatically or mechanically powered. The punch either includes a single die that travels across a matrix of paper, or other suitable material, punching holes corresponding to the light or dark areas on the master as it travels, or it includes a plurality of individually operated dies arranged in series across the mat and arranged such that operation of the dies in response to sensing of light or dark by the scanning device will punch holes through the mat. Either disclosed apparatus will thereby produce a punched matrix suitable for use in a silk screen printing operation.
A method of producing a silk screen matrix from an imaged master comprising sensing the images of a master to be copied; generating electrical signals corresponding to the sensed images; transmitting said electrical signals on a row-by-row basis to punch means; and feeding a matrix suitable for use in silk screen printing past said punch means such that said punch means is operated by said electrical signals to punch holes through the said matrix on a row-by-row basis, with each hole corresponding to a portion of a sensed image in a corresponding row on the master.
