Abstract: In accordance with one or more implementations of the apparatus, system and methods described, a sample measurement device is provided that is configured to measure the color of a sample. The sample measurement device includes at least one light source configured to illuminate the sample; at least one light sensor configured to output a signal in response to light emitted by light source and reflected off the sample being received by at least a portion of the light sensor; and a processor configured to receive the signal and calculate a color value for the sample, the processor configured to calculate the color value by at least adjusting the signal using a calibration factor.

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.
