Abstract: An image processing method is disclosed. The method includes receiving information relating to a print component to be used to print a target image; determining, based on the received information relating to the print component, half-toning parameters to be applied when generating a half-tone representation of the target image; and generating, using the determined half-toning parameters, a half-tone representation of the target image. An apparatus and a machine-readable medium are also disclosed.

Abstract: 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.

Abstract: As one example, a printer includes a density calculator to determine a content density of data on page to be printed and a controller. In that example, the controller may perform operations to determine a dry time for a swath of the page to be printed based on the content density and an environmental variable and adjust a parameter for the page to be printed to mitigate a drying time of the page to be printed based on the dry time determined for the swath.

Abstract: 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.

Abstract: Certain examples described herein relate to evaluating print quality. In these examples, a check image is printed at a first print quality in accordance with test image data for at least one test image, and a reference image is printed at a second print quality with reference image data corresponding to the one or more test images modified to simulate one or more print defects. A comparison of the printed reference image and the printed check image allows evaluation of a quality level for the printed check image.

Abstract: One example includes a printer (110) having a calculator (120) to determine plot density of a printer content page (130). A controller (140) is provided to set a print parameter based on the determined plot density for the printer content page (130) to mitigate dry time for a printed output page (150).
