Abstract: A spectral photoelectric measurement transformer comprises an array (10) of photoelectric transformer elements and dielectric interference bandpass filters (22a, 22b) disposed on a common filter support (21) connected upstream of them for sensitizing the transformer elements to different wavelength ranges of the measurement light. The bandpass filters are divided into a number of filter groups, each of which contains the same different bandpass filters within the filter group. An optical deflector element (30) spectrally shifts the effective bandpass curves of the bandpass filters of all the filter groups except one so that the effective bandpass curves of all the bandpass filters have different spectral positions. As a result, a multiplication of the filter channels effectively made available can be achieved using only a few different bandpass filters. Due to the small number of different bandpass filters, the measurement transformer is inexpensive to manufacture.

Abstract: A measuring system for photoelectrically scanning measurement points of a measurement object includes a lighting channel (21-24) for applying illuminating light to the measurement object (M) disposed in a measurement plane (MP) and a measuring channel (11-13) for capturing and photoelectrically converting the measurement light reflected by the measurement points of the measurement object M. The lighting channel and/or the measuring channel is configured so as to detect the reflection properties of the measurement points in several wavelength bands. The lighting channel (21-24) has a spatial light modulator controlled by an electronic control unit (40) for generating a spatial lighting pattern which causes illuminating light to be selectively applied to measurements points (25) of interest of the measurement object (M). The control unit (40) may be equipped with image processing functions and be configured to identify measurement points (25) suitable for the application purpose from image data of the measurement object (M) and to calculate corresponding lighting patterns for selectively illuminating the measurement points.

Abstract: To measure the colour of samples printed on a substrate containing brightener, a first spectral proportion of the total spectral reflection factor of the sample is measured by illuminating the sample with light having no UV element. From this first spectral proportion, a spectral correction factor is calculated making allowance for the characterisation data of the brightened substrate and the spectral properties of a selected type of illuminating light. The spectral correction factor is added to the first spectral proportion in order to obtain the total spectral reflection factor of the measured sample. The total spectral reflection factor is then evaluated for measuring and control purposes, in particular for calculating colour values of the sample. The characterising data of the substrate is determined on the basis of measurements taken with illuminating light with no UV element and with UV light only on a limited set of measurement samples, especially on the non-printed substrate only (paper whiteness). The measuring method has the advantages of a double measurement, which it requires physically but on a significantly reduced sample set only, which speeds up the measuring procedure considerably. The measurements needed for characterising the substrate may also be run with a separate measuring device, so that the measuring method can easily be implemented in existing colour measuring devices with interchangeable measuring filters or different light sources.

Abstract: A spectrometer is provided having a carrier, a light input for measurement light disposed on the carrier, a diffraction grating disposed on the carrier for dispersing the measurement light received from the light input, an opto-electronic detector disposed on the carrier for receiving and detecting the measurement light dispersed by the diffraction grating, at least one optical component for imaging the measurement light on the detector through the diffraction grating, a base board fastened to said carrier for supporting the opto-electronic detector, wherein the opto-electronic detector is fastened at a predetermined position on the base board, and wherein the base board and the carrier include positioning members for relatively positioning the base board on the carrier in a predetermined position. Preferably, the detector is a detector chip excluding a housing and fastened in a predetermined position on the base board. Both, carrier and base board have cooperating positioning members for positioning the base board on the carrier. The base board is preferably an electronic circuit board being fastened to the carrier in such a manner so as to allow a thermal expansion, and wherein the position of the fastening point P relative to the position of the detector on the base board is chosen such that the thermal expansion of the base board substantially compensates the drift of the spectral light component relative to the detector for at least an intermediate wavelength of the measured spectrum, the drift being caused by the thermal expansion of the diffraction grating and the carrier. In addition, the materials of the carrier, the base board, and the diffraction grating are selected with respect to their thermal expansion coefficients such that the temperature drift of the spectrum is substantially compensated for the entire measured spectrum. For most applications, the spectrometer is also sufficiently temperature compensated when using plastic components and is easily and economically produced.

Abstract: 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.

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.
