Abstract

Die Flexodruckmaschine, die, wie es nach einer Definition für den Flexodruck typisch ist, weist einen Druckzylinder mit einem weichen (flexiblen) Klischee und einem harten Gegendruckzylinder auf. Das flexible Klischee ist erfindungsgemäß sehr viel dünner als es beim Stand der Technik der Fall ist. Die Stärke des Klischees ist geringer als 1 mm. Auf den Druckzylinder ist eine Hülse aufgeschoben, die auf einem Rohr 1 aufgebaut ist und eine hochkompressible Schicht 2 aufweist, auf der eine gering oder im wesentlichen noch kompressible Sperrschicht 7 vorgesehen ist, die die beim Druck entstehenden Friktionskräfte aufnimmt, und auf der das Klischee befestigt ist. In vorteilhafter Weise liegt die Stärke des Klischees zwischen 0,5 und 0,8 mm. Durch die wesentliche Verringerung der Stärke des Klischees in Verbindung mit der Hülse, die kräfteresorbierend aufgebaut ist, wird eine wesentliche Qualitätsverbesserung erreicht. The flexographic press, which, according to a definition is typical for flexographic printing, has a printing cylinder with a soft (flexible) cliché and a hard one Impression cylinder on. The flexible cliché is according to the invention, much thinner than in the prior art Technology is the case. The strength of the cliché is lower than 1 mm. A sleeve is pushed onto the printing cylinder, which is built on a tube 1 and a highly compressible Has layer 2, on which a little or essentially still compressible barrier layer 7 is provided, which absorbs friction forces arising during pressure, and on the cliché is attached. Advantageously lies the thickness of the cliché between 0.5 and 0.8 mm. Through the substantial reduction in the strength of the cliché Connection with the sleeve, which is built up to absorb the forces a significant improvement in quality is achieved.
