  • Publication number: 20230166934
    Abstract: In an example of the disclosure, a first optical sensor positioned adjacent to a web path and having a first sensor beam is utilized to identify a first signal value as the first optical sensor detects an eye-mark as the web is moved along the web path. A second optical sensor positioned adjacent to the web path, downstream of the first optical sensor, and having a second sensor beam, is utilized to identify a second signal value as the second optical sensor detects the eye-mark. A lateral misalignment of the web is determined based upon the first signal value, the second signal value, and a lateral offset of the first sensor beam from the second sensor beam.

  • Patent number: 11238322
    Abstract: A position of a first registration mark printed on a substrate during an earlier printing operation is detected. A second registration mark is printed on the substrate during a current printing operation at a position on the substrate relative to the first registration mark based on the detected position of the first registration mark and a correction factor. An alignment difference between the position of the first registration mark and the position of the second registration mark is measured. A new correction factor for a subsequent printing operation is calculated by weighting the measured alignment difference according to a difference between the measured alignment difference and a previous measured alignment difference.

  • Patent number: 11232335
    Abstract: In an example, an apparatus comprising an image processor is configured to perform edge detection on the image to detect a plurality of edges, automatically identify a path across the image based on the detected plurality of edges, divide the image into two adjacent sub-images based on the determined path, and generate first and second print data to cause the printing device to print the two adjacent sub-images.

  • Patent number: 11163504
    Abstract: In some examples, a system selects a spanning region of an image spanning an intersection between adjacent sub-images that partition the image. The spanning region is divided based on a non-linear path that is determined on the basis of a user input, resulting in respective modified adjacent sub-images. Print data to cause a printing device to print the respective modified adjacent sub-images is generated on the basis of the dividing.

  • Patent number: 10990041
    Abstract: According to some examples, a method comprises successively transferring a series of images from an imaging surface to an intermediate transfer member, ITM, then from the ITM to positions on a web substrate. The method may comprise intermittently adjusting a position at which particular images are transferred to the ITM by a first defined distance laterally across the ITM and by a second defined distance longitudinally with respect to the ITM. The method may comprise adjusting a position at which the particular images are transferred to the web substrate by approximately the first defined distance laterally relative to the ITM and by approximately the second defined distance longitudinally relative to the ITM. The method may comprise, after a first defined number of intermittent position adjustments, changing a direction in which the position is adjusted. A print apparatus and a machine-readable medium are also disclosed.

  • Patent number: 10802770
    Abstract: A method and apparatus for generating print data are described herein. An apparatus comprising an image processor (110) is configured to select a region of an image spanning an intersection between at least two adjacent sub-images that partition the image. The spanning region is divided based on a non-linear path that is determined on the basis of a user input, resulting in at least two modified adjacent sub-images. Print data operable to cause a printing device (150) to print the respective modified adjacent sub-images are generated on the basis of the dividing.

  • Patent number: 9937741
    Abstract: A method and system for performing color print quality monitoring for a color printing process, the method includes determining a calibration distance (ZCAL) between a Spectrophotometer (140) and an associated calibration patch (310) that provides a maximum luminescence value (LMAX) detected by the Spectrophotometer. The Spectrophotometer (140) is calibrated at the calibration distance by taking a color reading. A first color patch distance (Z1) between the Spectrophotometer and a color calibration patch (320) printed on a sheet (155) is determined from a first maximum color patch luminescence value (L1). A first color reading of the color calibration patch is taken and a second color patch distance (Z2) between the Spectrophotometer and a different area of the color calibration patch (320) is determined to provide a second maximum color patch luminescence value (L2).

The Spectrophotometer (140) or patch distance (Z1) between the Spectrophotometer and a color calibration patch (320) printed on a sheet (155) is determined from a first maximum color patch luminescence value (L1). A first color reading of the color calibration patch is taken and a second color patch distance (Z2) between the Spectrophotometer and a different area of the color calibration patch (320) is determined to provide a second maximum color patch luminescence value (L2). A second color reading of the color calibration patch is taken and compared with the first color reading to determine if the printing process needs adjusting.
