Abstract:
The negative pressure in the ink chamber of a nozzle of a print head is reduced in a printing interruption phase, in particular upon transport of the print head from a cleaning position into a printing position, relative to the negative pressure in a printing phase. The leaking of ink during the printing interruption phase may thus be reliably avoided, and the print quality may be increased.

Claim (Index 13):
An inkjet printing device, comprising:\n a print head having at least one nozzle that is configured to eject ink droplets onto a recording medium in a printing phase to print a print image onto the recording medium; a negative pressure tank that stores ink and that is connected with the print head via an ink channel to provide ink for printing of a print image; a pressure adjuster configured to vary a physical pressure in the negative pressure tank to vary a physical rest pressure of ink in the nozzle; and a controller that is configured to:\n determine a presence of a printing interruption phase of a print head of the inkjet printing device or that a previous print preparation phase has been performed; and \n induce the pressure adjuster based on the determination to vary the physical rest pressure of the ink in the nozzle.
