Device for printing ink onto printing material
Abstract:
A printing device includes an ink jet print head having individually controllable nozzles for jetting ink drops. An ink line connected to a chamber has a feed and/or return line for the print head. The print head, ink line and chamber move jointly relative to printing material. The ink line is part of a circulation ink supply system for the print head. A mass element associated with the chamber has a position and/or shape relative to the chamber changing as a function of the joint movement so that the chamber volume is a function of the position and/or shape of the mass element to compensate for pressure fluctuations and/or movements of the ink and avoid problems in the ink supply system for a print head in industrial, high-performance ink jet printing and in cooperation with circulation ink supply systems conveying large volumes of ink.
