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.

Abstract: Methods and apparatus for developing a color mapping for mapping colors from a source gamut to an output gamut are described. In an example, defects in a printed output image are used to identify a region of an initial output gamut associated with a defect. A modified output gamut may be developed, the modified output gamut excluding the identified region. A color mapping for use in mapping colors from the source gamut to the modified output color gamut for producing an output image may also be developed.

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: 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.

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.

Abstract: A calibration-pattern printing method in a page-wide array printer having an array of print nozzles extending in a transverse direction of the printer comprises printing a respective calibration pattern portion on a substrate by at least one first portion of the nozzle array, changing the relative position of the nozzle array and substrate in the transverse direction then printing a respective further calibration pattern portion on the substrate by the at least one first portion of the nozzle array so that a given first nozzle-array portion prints a calibration pattern portion and further calibration pattern portion that are at least partially aligned with each other in the longitudinal direction and join up in the transverse direction to form an enlarged calibration pattern portion.
Abstract translation: 在具有在打印机的横向方向上延伸的打印喷嘴阵列的页宽阵列打印机中的校准图案印刷方法包括：通过喷嘴阵列的至少一个第一部分在基板上印刷相应的校准图案部分， 喷嘴阵列和基底在横向上的相对位置，然后通过喷嘴阵列的至少一个第一部分在基底上印刷相应的另外的校准图案部分，使得给定的第一喷嘴阵列部分打印校准图案部分，并进一步 校准图案部分，其在纵向方向上彼此至少部分对准并且在横向方向上连接以形成放大的校准图案部分。
