Patent number: 7894065Abstract: A method for the correction of measurement errors caused by surface effects induced by ink splitting during the color measurement of a printed sheet on a running printing device, includes scanning the printed sheet photoelectrically point by point and forming color and/or density measured values from scanning signals from the scanned points. Those scanned points which have a brightness exceeding a limiting value are identified, and the measured values are corrected by using the identified scanned points. In particular, during the formation of the color and/or density measured values, the scanning signals from the identified scanned points are not taken into account.Type: GrantFiled: January 29, 2008Date of Patent: February 22, 2011Assignee: Heidelberger Druckmaschinen AGInventors: Adrian Kohlbrenner, Peter Ehbets, Wolfgang Geissler

Patent number: 7821639Abstract: A scanner device includes a color measuring, a support surface for a measured object and a drive unit for moving the measuring head across the support surface and for adjusting the height of the measuring head in a direction perpendicular to the support surface. The measuring head is equipped with an illuminating channel and a collection channel. The illuminating channel has a light source and optical means for illuminating the measured object at a measurement site at a mean angle of incidence of 45°. The collection channel has optical means for capturing light emanating from the measured object at the measurement site at a mean collection angle of 0° and coupling it into a light guide, which directs the captured light to a wavelength-selective photoelectric transformer, which resolves it into a number of wavelength ranges and generates an electric measurement signal corresponding to each wavelength range.Type: GrantFiled: December 20, 2007Date of Patent: October 26, 2010Assignee: X-Rite Europe GmbHInventors: Peter Ehbets, Adrian Kohlbrenner

Patent number: 7755773Abstract: A scanner device for measuring the color properties of a measured object pixel by pixel has a support surface for the measured object, a color measuring head, a drive unit for moving the color measuring head above the support surface in at least one dimension thereof and for adjusting the height of the color measuring head in the direction perpendicular to the support surface, as well as a measurement and drive control unit which activates the drive unit and co-operates with the color measuring head. It is also equipped with an electronic distance control system which adjusts the distance of the color measuring head above the measurement point in the direction perpendicular to the support surface to a desired measuring distance for every measurement point by means of the drive unit. The electronic distance control system works with measurement values generated by the color measuring head and distance values computed from them.Type: GrantFiled: December 20, 2007Date of Patent: July 13, 2010Assignee: X-Rite Europe GmbHInventors: Peter Ehbets, Adrian Kohlbrenner

Patent number: 7679785Abstract: Image measurement values of a measurement object, in particular a printed sheet, measured by means of a photoelectric image measuring unit operating on the basis of pixels are corrected with respect to at least one influencing variable which influences the measurement result with a view to at least partially eliminating the effect of this influencing variable on the measuring process. The image measurement values measured by the image measuring unit are converted by correction parameters of a parameter-based correction model into corrected image measurement values which no longer contain the influencing variable affecting the measuring process. The correction parameters used for the parameter-based correction model are automatically calculated using reference measurement values measured at reference measurements points on preferably the same measurement object by means of a reference measuring unit and the image measuring unit.Type: GrantFiled: October 28, 2005Date of Patent: March 16, 2010Assignee: X-Rite Europe GmbHInventors: Peter Ehbets, Adrian Kohlbrenner, Harald Ammeter

Patent number: 7671992Abstract: The measuring device comprises a lighting system, a photoelectric receiver unit and optical means. The lighting system applies light to image elements disposed in strip-shaped lighting regions (15) at a standardized angle of incidence range. The photoelectric receiver unit comprises several photoelectric line sensors (21) disposed parallel at a distance apart which are sensitized to different wavelength ranges by color filters (22) connected upstream. The optical means comprise linear optical arrays (31) which pick up the measurement light reflected by the image elements at a standardized range of angle of reflection and direct it to one of the respective line sensors (21). By means of optical screening and other structural features, cross-talk effects between adjacent image elements are largely reduced.Type: GrantFiled: October 28, 2005Date of Patent: March 2, 2010Assignee: X-Rite Europe GmbHInventors: Peter Ehbets, Adrian Kohlbrenner, Beat Frick

Patent number: 7515267Abstract: In a method for determining color and/or density values for use in monitoring and regulating a printing process in a printing apparatus, specifically in a sheet-fed offset printing press, measuring areas of a printed sheet are measured photoelectrically during the printing process, directly in or on the running printing apparatus. From the measured values obtained in the process, the color and/or density values for the relevant measuring areas are formed. From the measurement, measured value deviations caused directly in the printing process with respect to a measurement outside the printing process can be corrected computationally.Type: GrantFiled: November 3, 2006Date of Patent: April 7, 2009Assignee: Heidelberger Druckmaschinen AGInventors: Peter Ehbets, Wolfgang Geissler, Adrian Kohlbrenner
