Abstract

Die Erfindung betrifft ein Druckwerk einer Druckmaschine, insbesondere einer Rollendruckmaschine, mit einem Formzylinder, mit einem auf dem Formzylinder abrollenden Übertragungszylinder (10), mit einem auf dem Übertragungszylinder (10) abrollenden Gegendruckzylinder, und mit einem Farbwerk, wobei mit dem Farbwerk Druckfarbe auf den Formzylinder, nämlich auf mindestens eine auf demselben positionierte Druckform, auftragbar ist, und wobei der Übertragungszylinder (10), der mindestens ein auf demselben positioniertes Gummituch oder eine Gummituchhülse trägt, die Druckfarbe auf einen Bedruckstoff, der durch einen zwischen dem Übertragungszylinder (10) und dem Gegendruckzylinder ausgebildeten Druckspalt hindurch bewegbar ist, überträgt. Erfindungsgemäß weist mindestens ein Zylinder, nämlich der Formzylinder und/oder der Übertragungszylinder (10) und/oder der Gegendruckzylinder, entlang seiner Axialerstreckung einen abgestuften Durchmesser auf.
