    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 color adjustment determination method is provided that includes forming a color adjustment image on a recording medium by moving a plurality of heads including a plurality of nozzles relative to the recording medium in a relative moving direction and ejecting liquid from the plurality of heads that are arranged in an orthogonal direction orthogonal to the relative moving direction, acquiring colorimetric values of a plurality of portions of the color adjustment image formed by the plurality of heads that are arranged at different positions in the orthogonal direction, calculating a color difference between at least two portions of the plurality of portions of the color adjustment image based on the colorimetric values of the plurality of portions, and determining whether at least one of the plurality of heads that have ejected the liquid requires adjustment based on the calculated color difference.

    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.
