Abstract: 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. In particular, image measurement values measured without polarization filters are converted into polarization filter image measurement values by means of this method. Influences induced by print medium, fluorescence effects and the influences of non-standard measuring geometries are also corrected.

Abstract: 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.

Abstract: For the color measurement of samples printed on a substrate including a brightener, a raw spectral reflection factor of the sample is measured in a first measurement by illumination of the sample with light without UV portion. In a second measurement, a fluorescence spectrum of the sample is measured by illumination of the sample with only UV light. The measured fluorescence spectrum is recalculated as a corrected fluorescence spectrum by weighting with spectrally dependent correction factors and, finally, the measured raw spectral reflection factor and the corrected fluorescence spectrum are added to form a corrected spectral reflection factor from which the values characterizing the color of the sample are then calculated. The spectral correction factors are determined during the device manufacture for a certain set of light types and stored in the device.

Abstract: A color management system using distributed profiles includes a color printer adapted to print controlled color using a custom profile. The color printer system creates a custom profile by reading its initial characterization data, the profiles of the inks and the profile of the paper used in the printer. The color printing system includes a spectral measurement module adapted to generate spectral measurement of an output of the color printer. The printing system computes its initial characterization data by using the output of the color printer, measured by the spectral measurement module. The printing system updates the paper profile, the ink profile and/or the printer characterization data based on the measurement of the spectral measurement module.

Abstract: 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. The scanner device is suitable for running high-precision measurements on even the smallest measurement fields without contact and no separate measurement sensor is needed for the distance control system.

The interface is a USB or Fire Wire interface and the power supply to all electrical components of the measuring device is carried out through the interface. Therefore a power supply circuit is provided which is connected to the interface for generating the necessary supply voltage for each of the individual electrical components of the measuring device from the supply voltage being supplied by the external computer via the interface. The use of a USB or Fire Wire interface allows the processing of the measurement data to be transferred into the external computer, thus allowing a particularly cost efficient manufacturing of the device so that the device becomes available to a wide range of users.

Abstract: A hand-held measurement device for appearance analyses includes a measurement array which comprises a number of illumination means for applying illumination light to a measurement field in at least three illumination directions and a number of pick-up means for capturing the measurement light in at least one observation direction. The illumination directions and the observation directions lie in a common system plane. At least one pick-up means is embodied to spectrally gauge the measurement light in a locally integral way, and at least one imaging pick-up means is embodied to gauge the measurement light in terms of colour in a locally resolved way. The spectral pick-up means and the locally resolving pick-up means are arranged such that they receive the measurement light reflected by the measurement field under the same observation conditions and in particular from the same observation direction.
