  • Patent number: 11223746
    Abstract: 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.

  • Publication number: 20210008877
    Abstract: An example of a printing system is disclosed. The example disclosed herein comprises a plurality of nozzles and a controller. The plurality of nozzles is to eject a printing agent on a substrate to print a print job. The controller is to receive the print job comprising an outline and a fill area to be printed. The controller is also to define a first subset of the plurality of nozzles as a first printing mode to print the outline. The controller is further to define a second subset of the plurality of nozzles as a second printing mode to print the fill area, wherein the second subset comprises more nozzles than the first subset. The controller is further to print the print job based on the first printing mode and the second printing mode.

  • Patent number: 10391762
    Abstract: The present disclosure discloses a page wide array (PWA) printer (20) particularly but not exclusively for performing print jobs while maximizing print bar performance uniformity within the printer. The PWA printer includes a print bar which can be moved laterally and a controller which causes the print bar to laterally move from a first to a second position and causes the nozzles within the print bar to print an image while the print bar is in the second position without modifying the lateral alignment of the image.

  • Patent number: 10350880
    Abstract: A method and system of controlling at least one printbar in a printing system are described. The printing system has one or more of printbars distributed along a media transport. A first image including a reference pattern is generated on a print medium with a first printbar. A pattern is then detected on the print medium. The reference pattern and the detected pattern are used to determine a position of the first image relative to a second printbar. This position is used to configure nozzle data for a second image to be generated on the print medium by the second printbar.

  • Patent number: 10343417
    Abstract: A method of generating a diagnostic plot for a printing system includes printing a first half of a diagnostic pattern representative of a first state of the printing system, and printing a second half of the diagnostic pattern representative of a second state of the printing system. Variation of the diagnostic pattern from an adjacent diagnostic pattern indicates the printing system is out of specification.

  • Patent number: 10000080
    Abstract: Example implementations relate to random wave mask generation. Some examples may distribute data points in a mask area based on a probability density function. The probability density function may have a maximum probability density located at a first edge and a second edge of the mask area. Some examples may also identify a wave curve that fits the data points. The wave curve may include oscillating waveforms of varying amplitudes. Some examples may also generate a random wave mask based on the wave curve.

  • Publication number: 20180154654
    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.

  • Patent number: 9962931
    Abstract: Examples include estimation of pen to paper spacing (PPS). Examples include an alignment pattern printed on a medium at a target speed, an optical scan procedure performed on the printed alignment pattern to determine values of cross-media misalignment for first and second portions of the alignment pattern, determination of a dynamic swath height error (DSHE) effect value based on the values of cross-media misalignment, and estimation of an amount of PPS based on the determined DSHE effect value and the target print speed.

  • Patent number: 9908323
    Abstract: A method and system of controlling at least one printbar in a printing system are described. The printing system has one or more of printbars (160, 190) distributed along a media transport. A first image including a reference pattern (240A, 240B) is generated on a print medium (150) with a first printbar (160). A detector (180) then detects a pattern on the print medium. The reference pattern and the detected pattern are used to determine a position of the first image relative to a second printbar (190). This position is used to configure nozzle data for a second image to be generated on the print medium by the second printbar.

  • Patent number: 9906686
    Abstract: Image processing transforms input multi-level image data into output image data having a smaller number of levels (the input and output image data represents images formed of cells). The image processing distributes quantization error of a target cell of the image to neighbor cells in proportions determined by a set of weights. The distribution excludes neighbor cells whose data level is less than a threshold value from receiving distributed quantization error, or allows just a fraction of the quantization error to be distributed to such neighbor cells.

  • Patent number: 9895915
    Abstract: Example implementations relate to swath height error compensation. Some examples may determine a density of an image to be printed in an overlap area of a printing material. The overlap area may include target pixels capable of being printed by a first set of drop ejection elements and a second set of drop ejection elements that are redundant to the first set of drop ejection elements. Some implementations may also determine a mask to apply to the first and second set of drop ejection elements based on the determined density, and the mask may designate at least one additional drop to apply to at least one target pixel in the overlap area by at least one of the first and second set of drop ejection elements. Some implementations may also apply the mask to the first set of drop ejection elements and the second set of drop ejection elements.
