Patent number: 10379790Abstract: In one embodiment, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to print a print job, and determine target color data for each sheet of the print job while printing the job. The instructions further cause the processor to continually save the target color data to a server for each sheet of the print job as each sheet is printed.Type: GrantFiled: June 29, 2018Date of Patent: August 13, 2019Assignee: HP Indigo B.V.Inventors: Gal Amit, Ran Waidman, Tsafrir Yedid Am

Patent number: 9124754Abstract: A method for position calibration of a spot of a known geometry of an optical sensor is disclosed. The method may include providing a position calibration patch on a sheet at a position which is known with respect to a reference position on the sheet, along a scan path of the spot of the optical sensor across the sheet. The patch may include at least two adjacent blocks of different colors. The method may also include obtaining a sampling of the position calibration patch using the optical sensor. The method may further include determining from the sampling a relative coverage of the spot over the color blocks of the position calibration patch, and based on the known geometry of the spot and on the determined relative coverage, determining the position of the spot of the sensor with respect to the reference position.Type: GrantFiled: June 8, 2011Date of Patent: September 1, 2015Assignee: Hewlett-Packard Indigo B.V.Inventors: Nadav Barkai, Lior Katz, Gal Amit

Patent number: 8469479Abstract: In one embodiment, a media is advanced in the process direction to cause a plurality of fiducials to successively appear within a sensor's focal width. Each fiducial includes a target and a background, with the target superimposed to the background. Each target has a substantially same target width, a substantially same optical density, and a position at a distinct distance from an edge of the media. Each background has an optical density less than the optical density of the targets and greater than an optical density of the media. An optical density for each fiducial is read utilizing the sensor. The target the sensor is most aligned with is discerned by identifying an identified fiducial with the highest-read optical density. Utilizing data indicative of a position of the discerned target relative to a desired position, the sensor is caused to move to the desired position.Type: GrantFiled: November 15, 2010Date of Patent: June 25, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Gal Amit, Ran Waidman, Oren Bengigi
