Abstract: As described herein, a method has been developed to estimate the gloss of a black or dark sample using a color measurement system. In such a system, when measuring a higher gloss sample, more illumination light reflected from the sample surface will be directed away from the receiving sensor, and thus less signal will be detected. Using a derived sensor-signal to surface-gloss relationship, the surface gloss of a sample can be calculated by applying the measurements of the sample to the signal to gloss relationship to obtain a more accurate gloss measurement of a sample under analysis.

Abstract: A method and a system are provided for obtaining improved spectra recovery results of a measurement of a sample through the use of a calibration matrix obtained from calibration measurement values using at least one illumination source. By calculating the reflectance spectrum of a collection of calibration samples across several rounds of measurements and cascading the results, an improved calibration matrix can be used to convert the sample measurement values to more accurate results.

Abstract: A method and a system are provided to measure transmittance or reflectance of a color specimen by using a transformation matrix obtained from the measurement values of a series of known transmittance or reflectance calibration color standards and multiple flashes from different illumination sources. A color spectrum can be determined with reduced error by calculating the reflectance spectra of an object using measurement matrices obtained under at least two illuminants and the transformation matrix.

Abstract: A method has been developed to monitor the aging of an illuminator (such as a lamp) and the interior sphere wall in a sphere-based color measurement instrument. This monitoring process or method is configurable to independently monitor the aging of the illuminator as well as the aging of the interior surface of a color measurement device using standard calibration measurements already present in the color measurement device.

Abstract: In one example, an initial transform is stored for converting wavelength channel responses of a color measurement instrument to color readings. The initial transform is set in-factory by a manufacturer of the color measurement device. A color selection of a sample is subsequently retrieved from a database, where the color selection was made by an end user in response to a color reading by the color measurement instrument using the initial transform. An adjustment to the initial transform is calculated using the color selection. The adjustment is then sent to the color measurement instrument for use in making future color measurements.

Abstract: A method is provided for identifying colors across illuminants using a processor configured by code executing therein, the method comprising capturing a sample image with an image recording device, the image including pixels resenting a color sample under analysis and a color reference chart. The processor is also configured to execute comparing the color values of pixels representing the color reference chart of the sample image to the pixel values corresponding to a plurality of entries within a plurality of color reference datasets to determine the color reference having the closest match of sample captured in the image. The reference identifier of the color that is the closest match to the sample is then output for further use.
