摘要： In an example print system including a mask engine and print engine, the mask engine is able to cause generation of print masks with disabled sections that are non-overlapping. In an example method of printing, a number of passes over a zone of media is identified, a plurality of print masks corresponding to the zone are generated with a disabled section of pixels that are non-overlapping, and the number of passes are printed based on the plurality of masks such that the disable pixels in each print mask are in a different relative position with respect to a location of the media.

摘要： There is disclosed a method comprising determining, by a processor, if there are consecutive nozzles of a print apparatus that are occluded by a contaminant; and, when a predetermined number of consecutive nozzles are occluded, automatically triggering a cleaning operation to at least partially remove the contaminant.

摘要： An example of a system for selecting print mode configurations is disclosed. The example disclosed herein comprises an array of nozzles to eject ink, and a controller. The controller is to instruct the array of nozzles to print a plurality of color patches, each color patch being printed using different nozzle setting values. Also, the controller is to receive a sensor signal from each color patch from a color sensor. The controller is further to derive color saturation and/or density measurement information from the sensor signals; and to select a print mode configuration based on the color saturation and/or density measurement information.
