Patent number: 9044959Abstract: Methods performed by a printing system are described herein. A portion of a print area is located by operating an optical sensor to respond to a color shift. The color shift is from a printed reference color. The color shift is caused by a fixer fluid applied to the portion. Printing systems and tangible machine readable storage mediums are also described herein.Type: GrantFiled: September 21, 2011Date of Patent: June 2, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Eduardo Amela Conesa, Jacint Humet Pous, Marc Serra Vail, Jaime Fernández del Rio

Patent number: 9004642Abstract: An apparatus and method for controlling a printing device are described. In examples, a printing device has a first printhead interface, a first printhead for use in applying a treatment fluid to a print medium and a second printhead interface, a second printhead for use in applying ink to the print medium. The first and second printhead interfaces are consecutively aligned along a common axis and each printhead has a plurality of nozzles that extend in a direction of relative movement of the print medium in relation to said printheads. An example apparatus then has a controller arranged to, when the printheads are installed, configure activation of nozzles of at least one of the first and second printheads in the direction of relative movement to spatially offset useable nozzles of the first printhead with respect to useable nozzles of the second printhead in said direction.Type: GrantFiled: January 28, 2013Date of Patent: April 14, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jaime Fernandez Del Rio, Jacint Humet Pous, Eduardo Amela Conesa, Marc Serra Vall

Patent number: 8985735Abstract: The present disclosure is related to deposition of print treatments. In an example, treatment is to be deposited on substrate dot locations to receive ink according to selected treatment-to-ink regimes. The selected treatment-to-ink regimes include a variable treatment-to-ink regime and a constant treatment-to-ink regime. The variable treatment-to-ink regime is for depositing a variable amount of treatment dependent on the amount of ink to be deposited in a substrate dot location when the ink amount in the substrate dot location is below a threshold. The constant treatment-to-ink regime is for depositing a selected constant amount of treatment in a substrate dot location and an area surrounding the substrate dot location when the ink amount in the substrate dot location is above the threshold. Other examples are illustrated herein.Type: GrantFiled: March 28, 2013Date of Patent: March 24, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jaime Fernandez del Rio, Eduardo Amela Conesa, Jacint Humet Pous, Marc Serra Vall

Patent number: 8922838Abstract: Application of treatments for treating a colorant for printing an image is described herein. In an example, an amount of a treatment to be applied on a substrate portion is determined considering color calibration of a printing system for specific conditions of printing the image. The treatment is for treating the amount of colorant on the substrate portion.Type: GrantFiled: September 7, 2012Date of Patent: December 30, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jaime Fernandez del Rio, Jacint Humet Pous, Eduardo Amela Conesa, Marc Serra Vall

Patent number: 8899712Abstract: A method performed by a printing system is described herein. A request is provided to a user to enter data related to print quality of a mark or marks printed on a portion of a background region. The background region includes an area or areas treated with a fixer fluid applied by a printhead. A user input is received associated to the request. A misalignment of the printhead is estimated in accordance with the user input. A printing system and a tangible machine readable storage medium are also described herein.Type: GrantFiled: August 31, 2011Date of Patent: December 2, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Marc Serra Vall, Maria Elizabeth Zapata, Eduardo Amela Conesa, Jacint Humet Pous, Jaime Fernández del Rio

Publication number: 20140232783Abstract: A printing method is described herein. A fixer fluid is applied to a print area. The areal density of fixer fluid in a boundary region of the print area is different than the areal density of fixer fluid in an interior region of the print area. The print area corresponds to an image portion to be printed with a uniform color.Type: ApplicationFiled: October 6, 2011Publication date: August 21, 2014Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Jaime Fernandez del Rio, Eduardo Amela Conesa, Marc Serra Vall, Jacint Humet Pous

Patent number: 8789907Abstract: According to one example, a printer includes an inkjet printhead, and the printhead comprises nozzles through which printing fluid is ejectable during a pass of the printhead across a print zone. Processing printhead control data includes obtaining printhead control data describing pixel locations in an image to be printed on a media, and allocating, for a swath of the image, each of the pixel locations to a printhead nozzle and to a print pass of a set of print passes in accordance with a print mask. The print mask defines sections associated different groups of the nozzles.Type: GrantFiled: November 30, 2012Date of Patent: July 29, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Marc Serra Vall, Eduardo Amela Conesa, Jaime Fernandez Del Rio, Jacint Humet Pous
