Printer with reversibly illustrated printing form has carrier layer for printing surface, positive or negative charges, and basic body

摘要

The flat-bed printing-form (2) has a carrier layer (5) whose surface used for printing is illustrated by positive or negative charges. The charges are anchored on the carrier layer by applying a charge on the carrier layer's surface not used for printing. The charge forms a counter-potential to the charges acting on the carrier layer which is placed on a fairly electrically-conductive basic body (3).
