DAMPING ROLLER FOR PRINTING PRESSES AND METHOD FOR THE PRODUCTION THEREOF

摘要

A damping roller for printing presses and a method for the production thereof, wherein a heat injected microporous special steel coating is applied to a cylindrical base body, is described. The average pore body of said coating is approximately 5 mum. A thicker moistening agent film is obtained by capillary force thereby enabling a higher moistening agent flow rate in the damping system of an off-set printing press.
