In a method and device for ascertaining print data for a print image to be printed, the print data is adapted and/or determined such that the time curve of the ink flow quantity, exhibits no quantity changes or flow rates due to which ink ejection errors might be produced, in particular nozzle failures. The device includes: a communication interface configured to receive the print data; and processing circuitry that ascertains, based on the print data, a time curve of an ink flow quantity of ink that, during the printing of the print image, flows in the print bar and/or is ejected from the one or more nozzles of the print bar; and determine, based on the time curve of the ink flow quantity, whether an ink ejection error will be produced.
A device for ascertaining print data for a print image to be printed by a print bar of an inkjet printing device, the print bar including one or more nozzles and the print data indicates, for a plurality of dots of the print image, a respective ink quantity that is to be ejected by a respective nozzle of the one or more nozzles of the print bar, the device comprising:
