Abstract: Differences between an offline spectrophotometer and an inline spectrophotometer can result in differences between a hardcopy target color and a printed reproduction of that color. The inline spectrophotometer is inside of a printer and configured to measure printer output. As such, the inline spectrophotometer cannot conveniently measure the hardcopy target color. A printing error or an instrument offset can be determined and passed to a color correction module that updates the device dependent color specification associated with the given spot color. This color specification may be stored, for example, in the printer controller, and used when a document subsequently calls for that spot color, thereby providing accurate color reproduction from that particular printer incorporating that particular inline spectrophotometer.

Abstract: A method for characterizing a primary radiant spectra of a projector includes projecting primary colors with a projector having a projector lamp and color filters. Measurements of each primary color are taken with a multi-band camera. Spectra of the color filters are estimated using the measurements from the multi-band camera. The primary radiant spectra of the projector are estimated using spectral data of the projector lamp and the estimated spectra of the color filters.

Abstract: A reference-color measurement step of obtaining a reference-color measurement value by measuring a spectroscopic-radiation luminance of a light being emitted from a reference-color portion in a measurement direction, or a tristimulus value thereof, using a light-source-color measuring instrument 5, without irradiating the reference-color portion with a light source for measurement, in a predetermined measurement environment; an objective-portion measurement step of obtaining an objective-portion measurement value by measuring a spectroscopic-radiation luminance of a light being emitted from a measurement-objective portion in the measurement direction, or a tristimulus value thereof, using the light-source-color measuring instrument 5, without irradiating the measurement-objective portion with a light source for measurement, in the measurement environment; and a color identification step of finding a color of the measurement-objective portion by means of computation from a ratio of the objective-portion measurement value with respect to the reference-color measurement value are equipped. Even when measuring a color of such a body, like a body including a fluorescent material, whose reflectivity has changed depending on the type of light source, it is possible to measure the color of such a body accurately.

Abstract: A method and an arrangement for testing the quality of multicolor patterned surfaces with an n-channel imaging sensor such as a color camera or an imaging spectrometer. The method determines from the captured images the deviations of the color/spectral statistics and of the image sharpness with respect to references and, before an assessment, converts at least one of the deviations or threshold values using a transformation which emulates the genetically and/or culturally specific perception of the targeted customer groups. The method further allows a quality produced to be associated with a genetically and/or culturally specific group of customers who accept this quality in terms of their perception of multicolor patterned surfaces.
