Abstract
A method is disclosed. The method includes receiving print job data, rasterizing the print job data to generate image data for each page of the print job data to be printed, calculating a coverage per unit area for two or more color planes of each page of the image data and calculating a flushing mask to flush nozzles of the inkjet print head.
Claims9
A method comprising:
- receiving print job data;
- rasterizing the print job data to generate image data for each page of the print job data to be printed;
- calculating a coverage per unit area for two or more color planes of each page of the image data;
