Abstract

A printing unit includes two screen-printing cylinders and two transfer cylinders that cooperate with the screen-printing cylinders and which define a printing gap or nip. At least one of the screen-printing cylinders has a screen surface and an interior doctor blade. A support element is provided for handling radially outwardly directed pressure exerted by the doctor blade on the screen surface in one section of the screen surface.
