Printing ink application method for e.g. offset printing machine, involves spraying ink on transfer cylinder using piezoelectrically activatable ejector units, and transferring ink directly or indirectly to form cylinder

摘要

The method involves spraying a printing ink on a transfer cylinder using piezoelectrically activatable ejector units (04), and transferring the printing ink directly or indirectly on a form cylinder of a printing machine by using a color deck. The ejector units are controlled individually or controlled in group. The ejector units are formed by piezoceramic tubes, which are moved opposite to each other in a transfer direction. An independent claim is also included for a printing unit of a printing machine.
