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

Patent number: 10341534Abstract: Example implementations relate to color compensation. Some examples may print a calibration target background on a non-opaque media. The calibration target background may have a color that increases a dynamic range of a set of color measurements of a calibration target foreground. Some examples may print the calibration target foreground over the calibration target background. Additionally, some examples may measure an optical density of the calibration target foreground with a reflective sensor and may calibrate a printer based on the measured optical density.Type: GrantFiled: August 26, 2014Date of Patent: July 2, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Juan Uroz Soria, Pere Gasparin Talarn, Antonio Gracia Verdugo

Patent number: 9375963Abstract: Techniques related to printer calibration are disclosed herein. In an example, an actual measurement of a colorimetric parameter is performed by measuring the colorimetric parameter on a printed calibration pattern. The colorimetric parameter is associated with an ink drop number. The calibration pattern is printed with selected printing conditions. An ink drop number variation is determined from a reference measurement and the actual measurement of the colorimetric parameter. The reference measurement is a measurement of a colorimetric parameter. The reference measurement corresponds to a measurement of the colorimetric parameter on a calibration pattern printed with the selected printing conditions. An actual linearization is generated by validating a set of pre-defined linearizations with the determined ink drop number variation. Other examples of printer calibration are disclosed.Type: GrantFiled: March 28, 2013Date of Patent: June 28, 2016Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jacint Humet Pous, Juan Uroz Soria, Pere Gasparin Talarn
