Abstract
A print bar comprises a mounting assembly and a plurality of drop-on-demand inkjet print modules mounted to the mounting assembly. The modules comprise conduits for continuously circulating ink. Each of the modules comprises a drop-on-demand inkjet print head and a local element for controlling the ink pressure, assigned to the print head. The print bar further comprises control circuitry assigned to the print heads of the modules for controlling the local elements for controlling the ink pressure and ink release by the print head. An optimum printing result at high frequency may be obtained from every print head as the ink delivered to the print head is locally brought to a desired pressure. A modular buildup is achieved, which means that new printers may be easily designed and built from a comparably small number of components to be held available. Maintenance is similarly facilitated. Scalability is excellent.
