    Abstract: Described herein is a process for correcting an observed color difference between a color at a first gloss and the color at a second gloss different than the first gloss, said process comprising the steps of: (a) determining a first correction caused by a lightness (Y-value) of the color a first gloss; (b) determining a second correction caused by an inclusion of a first surface diffusion in gloss readings; (c) based on the first and second corrections, determining a specular correction caused by a difference in specular reflections from the color at the first gloss and the color at the second gloss; (d) determining tristimulus corrections based on the specular correction; (e) preparing corrected tristimulus values of the color at a second gloss; and (f) producing a paint composition for the color at the second gloss using the corrected tristimulus values.

    Abstract: Apparatuses and methods for approximating a 5-angle color difference model are provided, where the 5-angle color difference model utilizes a 5-angle equation. In an exemplary embodiment, an apparatus includes a storage device for storing instructions and one or more processors configured to execute the instructions. The processor(s) are configured to receive 3-angle standard and test color measurements, and enter the 3-angle standard measurement into a neural network empirical model. The neural network empirical model includes a plurality of input nodes, a plurality of hidden nodes connected to the input nodes, and a plurality of output nodes connected to the hidden nodes. The neural network empirical model is configured to output 3-angle tolerance values, and to calculate a 3-angle color difference value using the 5-angle equation for at least one of the 3 color measurement angles using the 3-angle standard and test color measurements and the 3-angle tolerance values.

    Abstract: A printer moves a color chart relative to a spectrometer that carries out spectral measurement on the color chart. The color chart, which is a color measurement target of the printer, includes a color patch and a white portion that is positioned in a first position and a second position. The first position and the second position interpose a color measurement position, in which the color patch is disposed, along a predetermined direction. The printer acquires measured values by carrying out spectral measurement for the color measurement position, the first position, and the second position, determines a reference value corresponding to the color measurement position based on the measured values of the first position and the second position, and determines a color measurement result of the color patch based on the measured value of the color measurement position and the reference value.
