Abstract
An imprinter, particularly for use downstream of a flexographic printing machine, wherein the stubs at the ends of the counterpressure roller which forms part of the web guiding system are suspended on levers. The levers are pivotable about a horizontal axis defined by a pivot member on one or more carriages which are movable in the frame up and down to move the counterpressure cylinder nearer to or further away from two printing cylinders. The printing cylinders flank the counterpressure cylinder and their stubs are removably installed in open-sided sockets which are provided therefor in the sidewalls of the frame. Each printing cylinder receives ink from a discrete source.
