METHOD OF GENERATING PRINT DATA FOR INKJET PRINTHEAD

摘要

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.

1. A method of generating print data for an inkjet printhead having a plurality of ink planes, the method comprising 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 of the printhead 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 of the printhead; and sending the second print data, or third print data based on 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, wherein 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.
