Patent number: 11363170Abstract: Examples of an apparatus and method for use with a printing system are described herein. A correction to be applied to a printing system during print calibration is obtained. A distortion is applied to the correction. A relationship between an expected and measured output of the printing system is determined based on the print performed at least in part on the distorted correction. The printing system is calibrated on the basis of the determined correction.Type: GrantFiled: July 20, 2016Date of Patent: June 14, 2022Assignee: HP Indigo B.V.Inventors: Tsafrir Yedid Am, Rivay Mor, Pavel Blinchuk

Patent number: 10348936Abstract: Methods of measuring colors, methods of calibrating printers and printing systems for implementing the methods are disclosed. Calibration maps are printed on print media. The calibration maps have intertwined contiguous printed and non-printed areas. One or more color signals are measured on contiguous printed areas. One or more noise signals are measured on non-printed areas that are adjacent to the contiguous printed areas. Clear color signals are generated by removing the one or more measured noise signals from the one or more measured color signals.Type: GrantFiled: January 30, 2015Date of Patent: July 9, 2019Assignee: HP Indigo B.V.Inventors: Sagi Yehonatan Refael, Pavel Blinchuk, Iliya Shahamov

Patent number: 10081209Abstract: A method for determining a printing position, such as for image-on-paper registration in a printer or photocopying machine, is disclosed. A fiducial mark pattern comprising a plurality of fiducial marks at predefined relative distances is provided on a printing medium, and is scanned. The fiducial marks and a first edge of the printing medium are identified in a scanned representation of the printing medium. A first distance between the first edge and a first fiducial mark is determined, and a second distance between a second fiducial mark and a third fiducial mark are likewise determined from the scanned representation of the printing medium. The distance between the fiducial mark pattern and the first edge is computed based on both the determined first distance and the determined second distance. The invention also relates to a corresponding system and a computer-readable medium for determining a printing position.Type: GrantFiled: August 25, 2017Date of Patent: September 25, 2018Assignee: HP INDIGO B.V.Inventors: Rodolfo Jodra Barron, Sagi Refael, Eyal Bodinger, Pavel Blinchuk

Patent number: 9946187Abstract: A method of controlling a print engine, the method comprising: printing a first test image including a number of scans of printing components at a first setting of the array of printing components; printing at least a second test image by a number of scans of the printing components at a modified setting of the array of printing components, the modified setting being different from the first setting, wherein the modified setting provides a modified setting for each one of the printing components which is varied according to the position of the respective printing component in the array; optically scanning the printed test images and determining the distinctiveness of a scan band within the printed test images for each one of the test images; and deriving an optimum setting of the array of printing components from a comparison of the determined distinctiveness.Type: GrantFiled: January 31, 2014Date of Patent: April 17, 2018Assignee: HP Indigo B.V.Inventors: Tsafrir Yedid Am, Haim Vladomirski, Pavel Blinchuk
