    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.

    Abstract: An apparatus and method for providing a solution that enables technicians or other technical professionals to obtain accurate gloss, haze and DOI values for a reflecting sample due to the surface conditions of the sample. The apparatus and method allow for the generation of a data model of the surface of a sample using a sensor array designed to detect the divergence of a collimated beam of light reflected off the surface of the sample. The same principle enables technical professionals to obtain accurate haze and clarity values for a transparent or translucent sample that is trans-illuminated by light.

    Abstract: A system including a processor and a memory configured to store code executed by the processor is provided. In one or more implementations, the processor is configured by the code to calibrate measurements made by color measurement devices. In one particular implementation, the processor receives a measurement dataset of one or more color values, for a sample obtained by a color measurement device. The processor is configured to convert the measurement dataset to a standard space measurement dataset using a standard space measurement model and calculate a color dataset based on the standard space measurement dataset using a color conversion model. The processor is further configured to output the calculated color dataset to at least one of a display, database or local memory store.

    Abstract: In accordance with particular implementations of the invention described herein, a sample for analysis is illuminated under each of one or more narrow-band light sources. The light incident upon this sample is received by a sensor that generates measurement data in response thereto. One or more processors are configured to receive the measurement data and derive an excitation response curve and a fluorescent response curve from the measurement data. The processor is further configured to generate a fluorescent profile value using measurements from the fluorescent response curve for each of the captured narrow band measurement data and an excitation profile value corresponding to the area under the fluorescence curve divided by the area under the excitation curve. The generated fluorescent profile and excitation profile are both output as a dataset providing improved measurement values over similar approaches in the art.
