Abstract: A process and an apparatus for the preparation of color formula for the reproduction of the color of a master are described. In the process, during a measurement, the gloss component of the reflected light is already suppressed with polarizing filters, so that the calculation of the colorant concentrations may be carried out independently of the surface conditions of the master to be reproduced (glossy, semigloss, matte) with a set of optical data of the colorants that are independent of surface conditions.

Abstract: A method of optically measuring chromatic densities of a sample. In the method, three stimulus values, X, Y and Z, of light reflected from the sample, are derived. A cyan density, a magenta density and a yellow density are determined for the sample, using the X, Y and Z stimulus values, and in addition, three stimulus values, Xo, Yo and Zo of a standard color, such as white. With this method, a color image of an original picture may be accurately reproduced with a high fidelity.

Abstract: In a color measuring instrument, an integrating sphere is used to illuminate the sample and fiber optics are used to carry light diffusely reflected from the sample and from an interior wall of the sphere to a spectrometer. The transmitting ends of the fiber optic bundles are fixed in the housing of the spectrometer as entrance slits for the spectrometer, which includes a fixed grating and one or two arrays of photodetectors to detect the spectra dispersed by the grating from light received from the two transmitting ends.

Abstract: A real-time color comparator which performs color comparisons of sample objects to a reference color for the purpose of identification, sorting or matching. Two optical paths are positioned to collect the light from a reference object and a sample object and the light outputs from the two paths are directed onto a spherical dispersive element shown in the form of a concave diffraction grating that decomposes each light signal into its spectral constituents which are imaged on a dual photodetector array. The color signature from the reference and the color signature from the sample are compared.

Abstract: A colorimeter for measuring color of an object, in particular for measuring the color of liquids such as paints in a process stream. In the colorimeter, a single analytical light beam, with its blue and red intensity ratio controlled through a feedback loop, is directed to a sample whose color is being measured. A portion of the analytical light beam is reflected from the sample into a grating monochromator which disperses the light beam into its spectra. A detector array is attached to the monochromator which converts the spectra of the light beam into discrete signals which are then multiplexed with instrument status and reference color signals into an A/D converter. The output of the A/D converter is then fed directly to a computer programmed to directly provide standard color values.

Abstract: Systems and methods spectrally and radiometrically calibrate an optical spectrum detected with a color-image sensor of an optical spectrometer. When the color-image sensor includes a Bayer filter, the red-peaked, green-peaked, and blue-peaked spectral responses of the color filters forming the Bayer filter may be used to identify unique spectral signatures in the red, green, and blue color channels. These spectral signatures may be used to associate calibration wavelengths to the pixel locations of the color-image sensor where the spectral signatures are observed. A fitted model may then be used to associate a wavelength to each pixel location of the color-image sensor. These systems and methods account for translational shifts of the optical spectrum on the color-image sensor induced by optical image stabilization, and thus may aid optical spectrometry utilizing a digital camera in a smartphone or tablet computer.

Abstract: In order to provide a technique by which a highly-accurate conversion rule of measurement values between different spectrocolorimetric devices can be easily set, the spectrocolorimetric device includes a light source, a light-receiving unit, and a conversion unit. The light-receiving unit spectroscopically disperses reflected light generated on a surface of an object according to irradiation of the object with illumination light emitted from the light source and measures a spectroscopic spectrum of the reflected light. The conversion unit calculates a spectral reflectance that can be acquired by another spectrocolorimetric device from the spectroscopic spectrum by using a calibrated spectral sensitivity of the other spectrocolorimetric device different from the spectrocolorimetric device and the spectroscopic spectrum.
