Abstract: An inkjet printing assembly is configured for providing an imaging liquid on a recording medium. The inkjet printing assembly comprises a transport path for transporting an intermediate medium and the inkjet printing assembly has arranged along said transport path a first inkjet print station for ejecting a process liquid on an intermediate medium prior to ejecting the imaging liquid on the intermediate medium; a second inkjet print station for ejecting the imaging liquid on the intermediate medium; a spreading treatment station arranged between the first print station and the second print station for treating the process liquid on the intermediate medium before receiving the imaging liquid on the intermediate medium; and a transfer station for transferring at least the imaging liquid from the intermediate medium to the recording medium.

Abstract: An inkjet printing assembly is configured for direct inkjet printing on a recording medium and for indirect inkjet printing via an intermediate medium. The inkjet printing assembly comprises a transport path for transporting a print medium. Further, a control unit is provided for selecting the print medium, wherein the print medium is may at least be a recording medium or an intermediate medium. An inkjet print station is provided and arranged along the transport path for providing droplets of a liquid on the print medium. A transfer station is provided and configured for transferring the droplets of the liquid from an intermediate medium to a recording medium. A recording medium output station is provided for receiving the printed recording medium.

Abstract: A method is provided for actuating an liquid discharge element in an array of discharge elements of a print head. The liquid is provided to the elements of the array through a channel in the print head. A discharge element is provided with a driving signal from a set of signals comprising a discharging signal, a non-discharging signal, and a null signal. Only the first signal generates a drop of liquid, the second and third do not. An amount of discharging signals supplied to the print head is determined in accordance with a required number of droplets. A ratio of non-discharging signals versus null signals for the elements that do not discharge a drop of liquid increases with increasing amount of discharging signals. The elements receiving an non-discharge signal are selected randomly from the elements not discharging a drop of liquid. This extends the time that the print head may be operated without maintenance.
