Abstract: A method of generating print data for an inkjet printhead having a plurality of ink planes. The method includes the steps of: receiving image data for a print job in a printer controller; retrieving keep-wet pattern data for each ink plane of the printhead, the retrieved keep-wet pattern data being determined using one or more input parameters; generating first print data for each ink plane in the printer controller based on the received image data; merging the first print data with the keep-wet pattern data to provide second print data for each ink plane; and sending the second print data from the printer controller to the printhead, thereby causing the printhead to print an image together with a keep-wet pattern. The keep-wet pattern is defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead.
