Abstract
Described are a system and a method to activate an actuator for a first nozzle of a plurality of nozzles of an inkjet printing system. The inkjet printer system can be configured to generate triggers with a frequency for printing of a respective line of pixels by the plurality of nozzles. The frequency of the triggers can depend on a print speed of the inkjet printing system, and the print speed can be modifiable. A time period between two successive triggers can correspond to a total duration available to the first nozzle for an ink firing for printing of a pixel of the line. An indicator for a current print speed of the inkjet printing system can be determined. Depending on the indicator for the current print speed, a waveform for activation of an actuator can be defined to produce an ink firing for printing of the pixel of the line on the recording medium by the first nozzle within the total duration available at the current print speed. The waveform can be defined such that, depending on the indicator for the current print speed within the total duration available at the current print speed, the waveform includes: a prefire portion for excitation of a meniscus of the first nozzle without firing the ink droplet, and a fire portion for firing the ink droplet from the first nozzle.
