Publication number: 20220146972Abstract: An example of printing calibration includes printing a calibration page having test patches, the test patches developed at a plurality of voltages of a binary ink developer. The test patches are measured to determine an indication of ink thickness of the patches and a calibration voltage is generated based on the indications of the ink thickness of the test patches.Type: ApplicationFiled: July 17, 2019Publication date: May 12, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Yoav Landau, Ran Waidman, Nir Guttman

Patent number: 10992822Abstract: Example aspects described herein relate to an apparatus for adjusting control parameters of a printing substance for a printing system. Such adjustments may occur in conjunction with a color calibration process of the printing system.Type: GrantFiled: July 12, 2017Date of Patent: April 27, 2021Assignee: HP Indigo B.V.Inventors: Lior Joseph, Yoav Landau, Noam Parvin

Patent number: 10877419Abstract: In one example of the disclosure, a first print engine is caused to print a first image in a first set of sectors of a substrate. A second print engine is caused to print a second image in a second set of sectors of the substrate. The second print engine is caused to print a cover-up image over an incidence of the first image printed by the first print engine. The second print engine is caused to print a calibration image upon the cover-up image.Type: GrantFiled: June 30, 2017Date of Patent: December 29, 2020Assignee: HP INDIGO B.V.Inventors: On Mashiach, Yoav Landau

Patent number: 10759199Abstract: In one example in accordance with the present disclosure, a printing system is described. The printing system includes multiple print engines to form printed marks on a substrate. Each print engine prints non-sequential pages of a print job. A sensor of the printing system detects, for each page, a trailing edge gap size and a leading edge gap size. A controller of the printing system, based on a difference between trailing edge gap sizes and leading edge gap sizes for a set of pages of a print job, adjusts a printing operation to equalize subsequent trailing edge gap sizes and leading edge gap sizes.Type: GrantFiled: July 23, 2019Date of Patent: September 1, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: On Mashiach, Yoav Landau

Patent number: 10518534Abstract: In one example of the disclosure, a first print engine is to print a first image in a first area of a web substrate, and is to leave blank a second area of the web substrate. The printed first image includes a set of fiducials 1-n. For each of fiducials 1-n, a fiducial position error is determined based upon a comparison of the detected position and a predicted position for a subject fiducial. A substrate advancement error is calculated based upon an average of the determined fiducial position errors. An insertion point is determined based upon the substrate advancement error. The insertion point is a point at which a second print engine in-line with the first print engine is to begin printing a second image in the second area.Type: GrantFiled: June 28, 2018Date of Patent: December 31, 2019Assignee: HP Indigo B.V.Inventors: Yoav Landau, On Mashiach
