Abstract
A method is disclosed.

Claims25
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;
- and
- calculating a flushing mask to flush nozzles of the inkjet print head.
A printer comprising:
- a control unit to receive print job data, rasterize the print job data to generate image data for each page of the print job data to be printed, calculate a coverage per unit area for two or more color planes of each page of the image data and calculate a flushing mask;
- and
- an inkjet print head having a plurality of ink nozzles flushed according to the flushing mask.
An article of manufacture comprising a machine-readable medium including data that, when accessed by a machine, cause the machine to perform operations comprising:
- receiving print job data;
