Patent number: 11789667Abstract: Apparatus is described that comprises a printer carriage (100), comprising a printhead (105), at least one sensor (101, 102) for scanning an image deposited on a print media by the printhead (105) and a spectrophotometer (104) connected to the at least one sensor (101, 102) for generating data based on a reference image (120) on a test print media (110). The sensor (101, 102) is calibrated based on the generated data to detect a specific ICC profile, and wherein, in use, the sensor (101, 102) scans and digitizes an image of a final print media as the image is being printed on the final print media; and wherein the sensor (101, 102) is connected to a controller (106) that performs image quality analysis of the digitized image to determine whether colour deviation has occurred.Type: GrantFiled: November 5, 2019Date of Patent: October 17, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Gianni Cessel, Santiago Felez Navarro, Marcos Casaldaliga Albisu

Publication number: 20230267294Abstract: A colorant value adjustment method is disclosed. The method comprises obtaining data defining colorant values for a plurality of print addressable locations representative of pixels of an image to be printed during a printing operation, wherein each colorant value is representative of an amount of colorant to be delivered from a print nozzle to a corresponding print addressable location as the print nozzle moves between the print addressable locations during the printing operation. The method comprises determining, based on the obtained data, a measure of time that the print nozzle is not to deposit colorant immediately prior reaching a first print addressable location. The method comprises determining, based on the determined measure of time, an adjustment to be applied to the colorant value at the first print addressable location. The method comprises applying the adjustment to the colorant value for the first print addressable location. An apparatus and a machine-readable medium are also disclosed.Type: ApplicationFiled: July 2, 2020Publication date: August 24, 2023Applicant: Hewlett-Packard Development Company, L.P.Inventors: Marcos CASALDALIGA ALBISU, Maurizio BORDONE, Li QIAN, Carles CARMONA CALPE

Patent number: 11509798Abstract: In one example in accordance with the present disclosure, a printing device is described. The printing device includes a print controller with a processor and memory. The print controller generates print instructions. Specifically, the print controller receives print image data representing an image to be printed and identifies enclosed regions in a background print agent plane. The print controller also determines a size of the enclosed regions of background print agent plane and responsive to the size of an enclosed region being smaller than a threshold size, removes the enclosed region from the background print agent plane. The printing device also includes a print agent distribution system to apply the background print agent and the image print agent to a substrate according to the print instructions.Type: GrantFiled: March 1, 2021Date of Patent: November 22, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jordina Torrents Barrena, Marcos Casaldaliga Albisu, Carles Carmona Calpe
