Publication number: 20230264481Abstract: The disclosure relates to the analysis of digital contone image data (302) to compensate for a printing artefact, by identifying overlapping segments (202, 204) where print agent is to be printed in adjacent bands of the image, and defining a compensation for the artefact in an edge region (208) of a segment (204) based on an evaluation of an artefact criterion. Adjusted digital contone image data (316) is defined based on the compensation.Type: ApplicationFiled: July 2, 2020Publication date: August 24, 2023Applicant: Hewlett-Packard Development Company, L.P.Inventors: Eduardo AMELA CONESA, Marta BLANCH PINOL, Diana CANTO ESTANY

The method includes producing at least one sample print and calibrating misalignment of the superpositioned layers at a plurality of calibration locations on the sample print. The resultant misalignment data is provided to a morphing program to pre-deform the digital image to provide a modified digital image which compensates for misalignment during printing. The image is then printed using the modified digital image. An apparatus and a machinereadable storage medium comprising instructions executable by a processor are also disclosed.Type: GrantFiled: June 26, 2019Date of Patent: May 16, 2023Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Eduardo Amela Conesa, Diana Canto Estany, Marta Blanch Pinol

Patent number: 11318735Abstract: Method and devices for dynamically preventing printing errors caused by a media deformation are disclosed. In one example, a pen to print media space (PPS) distance is measured. A media deformation is identified in response to measuring the PPS distance. A corrective function is identified in response to identifying the media deformation. The corrective function identified is then performed. The proposed method provides for consistent quality across a print.Type: GrantFiled: June 18, 2018Date of Patent: May 3, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Santiago Sanz Ananos, Juan Uroz, Eduardo Amela Conesa, Francisco Lopez Moral, Marta Blanch Pinol, Diana Canto Estany

Publication number: 20220072855Abstract: A printing apparatus is disclosed. The printing apparatus comprises a printhead and a controller. The printhead includes an array of nozzles, each having an actuator to eject a printing fluid, the array of nozzles having a first and a second subset of nozzles, wherein the first subset is located at the vicinity of an edge of the printhead. The controller is to assign a firing mask so that the actuators corresponding to the first subset of nozzles are instructed to eject the printing fluid with a higher energy level than the actuators corresponding to the second subset of nozzles.Type: ApplicationFiled: April 29, 2019Publication date: March 10, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Marta Blanch Pinol, Diana Canto Estany, Eduardo Amela Conesa
