Abstract

Die Druckform umfaßt eine Halbleiterschicht. In dieser werden durch Dotierung kapazitive oder induktive Bereiche erzeugt. Jedem dieser Bereiche ist ein selektiv ansteuerbares elektronisches Schaltelement zugeordnet. Mit dem Schaltelement kann entsprechend dem zu druckenden Motiv der jeweilige kapazitive oder induktive Bereich aufgeladen bzw. erregt werden. In diesem Zustand können über eine entsprechende Einfärbevorrichtung dem Formzylinder Farbe, beispielsweise Ferro-Fluidfarbe, zugeführt werden, die dann an den erregten bzw. geladenen Bereichen haften bleibt. Durch Anlegung der Steuerleitungen an Masse oder an entgegengesetzte Polaritäten ist eine Entladung möglich. Ladung und Entladung können auch während des Betriebes vorgenommen werden.
