According to one example of the present invention, there is provided a method of generating data to control the ejection of ink drops from a plurality of arrays of printhead nozzles of a printing system. In the printing system one of the arrays of nozzles is configured to eject a first ink of a first colour having a first colourant density. Another one of the arrays of nozzles is configured to eject a second ink of the first colour having a second colourant density. Each array of nozzles is capable of making ink marks having a plurality of different ink mark volumes on a media. The method comprises obtaining image data for a single colour channel and generating, from the image data, multi-level screen data describing, for each of the first and second inks, the ink mark volume to be made by the array of printhead nozzles at each screen location.
A method of generating data to control the ejection of ink drops from a plurality of arrays of printhead nozzles of a printing system, one of the arrays of nozzles configured to eject a first ink of a first colour having a first colourant density, and one of the arrays of nozzles configured to eject a second ink of the first colour having a second colourant density, each array of nozzles capable of making ink marks having a plurality of different ink mark volumes on a media, the method comprising:
A tangible, machine-readable medium that stores machine-readable instructions executable by a processor to provide a method of generating data to control the ejection of ink drops from a plurality printheads one of the printheads configured to eject a first ink of a first colour having a first colourant density, and one of the printheads configured to eject a second ink of the first colour having a second colourant density, each printhead configured to make ink marks having a plurality of different ink mark volumes on a media, the tangible machine-readable medium comprising:
