Abstract
A method for printing waveforms, such as overlong waveforms, can be used to enable the printing of large ink droplets. The method can include determining whether the first waveform is longer than the duration and inducing the continued activation of a nozzle arrangement with the first waveform at a second activation point in time based on the determination that the first waveform is longer than the duration. The method can include the suppression of a new activation of the nozzle arrangement to ensure the execution of the first waveform (e.g., an overlong waveform).
Claims20
A method to activate a nozzle arrangement, a recording medium and the nozzle arrangement being moved relative to one another in a transport direction, the method comprising:
- activating the nozzle arrangement at a sequence of activation points in time to print a corresponding sequence of pixels of a column of a print image in the transport direction on the recording medium, wherein a time interval between a first activation point in time and a subsequent second activation point in time of the sequence of activation points in time corresponds to a time duration;
- determining that the nozzle arrangement should be activated with a first waveform at the first activation point in time;
- determining whether the first waveform is longer than the time duration;
- and
- inducing the continued activation of the nozzle arrangement with the first waveform at the second activation point in time based on the determination that the first waveform is longer than the time duration.
An inkjet printing system, comprising:
- at least one print head for printing a print image on a recording medium, the at least one print head including a plurality of nozzle arrangements configured to print a corresponding plurality of columns of the print image, wherein the recording medium and the plurality of nozzle arrangements are moved relative to one another in a transport direction;
- and
- a controller configured to:
- activate a nozzle arrangement of the plurality of nozzle arrangements at a sequence of activation points in time to print a corresponding sequence of pixels of a column of the print image in the transport direction on the recording medium, wherein a time interval between a first activation point in time and a subsequent second activation point in time of the sequence of activation points in time corresponds to a time duration;
- determine that the nozzle arrangement should be activated with a first waveform at the first activation point in time;
- determine whether the first waveform is longer than the time duration;
- and
- induce the continued activation of the nozzle arrangement with the first waveform at the second activation point in time based on the determination that the first waveform is longer than the time duration.
