Abstract
In a method and system for increasing print quality, activation pulses are activated with which a nozzle of an inkjet printing device to print dots on a recording medium. The activation pulses may be adapted based on sensor data with respect to already printed dots. The method and system can further include an automatic adaptation of the activation pulses to increase print quality even given the presence of soiling at the nozzle.
Claims13
A device for increasing the print quality of an inkjet printing device having at least one nozzle and being configured to produce, in reaction to an activation pulse, an ink ejection to print a dot of a print image on a recording medium, the device comprising:
- an interface configured to receive sensor data corresponding to at least one dot printed by the at least one nozzle;
- and
- processing circuitry configured to adapt the activation pulse for printing a subsequent dot based on the sensor data.
A method for increasing the print quality of an inkjet printing device having at least one nozzle that is configured to produce, in reaction to an activation pulse, an ink ejection for printing a dot of a print image on a recording medium, the method comprising:
- determining sensor data corresponding to at least one dot printed by the at least one nozzle;
- and
- adapting the activation pulse for printing of a subsequent dot based on the sensor data.
