Varnishing apparatus on offset printing machines

摘要

The invention relates to a varnishing apparatus on offset printing machines. The aim of this invention is to design the varnishing apparatus for motif-related varnishing in such a way that the setting-up time is shortened and the work is made easier. The object of the invention is to eliminate the repeated shifting of the rubber blanket on the blanket cylinder during the setting-up operation for motif-related varnishing. According to the invention, this is achieved in that the blanket cylinder is provided with a register adjustment device which acts both in the circumferential and in the lateral direction. <IMAGE>
