Abstract: The invention relates to a computer implemented process for matching a paint to the visual appearance properties of a painted substrate surface comprising the steps of a) selecting a potentially matching first candidate paint based on a first paint recipe comprising one or more colour and/or effect imparting toners, b) applying the first candidate paint to a test panel to obtain a first painted test panel c) visually comparing the appearance properties of the painted substrate surface and the first painted test panel under more than one viewing angle, wherein the visual comparison comprises c1) selecting a visual appearance category wherein the appearance of the painted test panel most prominently deviates from the painted substrate, wherein the categories are selected from a number of pre-defined visual appearance categories displayed on an output device of a computer, c2) inputting the selected visual appearance category in an input device of the computer, c3) visually determining the visual appearance difference of the painted test panel and the painted substrate in the selected appearance category, d) entering the determined visual appearance difference in an input device of the computer, e) optionally, entering only the types of toners of the candidate paint in an input device of the computer, f) providing a paint recipe modification advice consisting an advice of increasing or reducing one or more of the toners in the recipe, or adding an additional toner to the recipe or, on an output device of the computer, wherein the computer software provides the modification advice on the basis of i) the entered visual appearance difference and ii) a database in which only visually determined appearance properties of available toners under two or more viewing angles are stored, with the aim to minimize the appearance difference, g) preparing a second candidate paint based on the recipe modification advice, h) applying the second candidate paint to a test panel to obtain a second painted test panel, and i) repeating steps c) to h) until the visual comparison in step c) indicates that the candidate paint sufficiently matches the appearance properties of the painted substrate surface.

Abstract: A color measuring apparatus includes a measurement assembly which includes at least one illumination assembly for applying substantially parallel illumination light to a measurement spot of a measurement object and a pick-up assembly for capturing the measurement light radiated back from the measurement spot in an observation direction and for converting the same into corresponding electrical signals. The illumination assembly includes at least two illumination subassemblies which illuminate the measurement spot from different illumination sub-directions near a first preset nominal illumination direction, each with preferably parallel illumination light. By the illumination from different illumination sub-directions slightly deviating from the nominal illumination direction, angular errors of the illumination assembly can be compensated for in a simple manner.

Abstract: A multi-angle colorimeter employs a multi-angle mode and a symmetrical arrangement mode in an optical arrangement. Light detection on both sides of the symmetrical arrangement is performed by a single photodetector unit. The photodetector unit is used on both sides, and thus, the device becomes simpler, without any impact on individual difference in characteristics of multiple photodetector units. Conversely, elements for illumination can be used on both sides. Also in a case where multiple photodetector units are used, the size and cost of the device can be reduced with the use of a photodetector unit having a relatively low wavelength resolution as a photodetector unit to be used on one side. This enables to reduce an attitude error due to relative tilting of a measurement surface while reducing the size and cost of the device.

Abstract: A system and method of characterizing a color variation of a surface includes a device having a light source and a plurality of sensors positioned at respective viewing angles. An algorithm is stored on and executable by a controller to cause the controller to direct a beam of light at the measurement location with the light source and measure the light leaving the measurement location with the sensors at a plurality of azimuth angles to obtain respective measured color values. The controller is configured to define a color vector function F(θ, φ) to represent the color variation of the surface. The controller is configured to determine the color vector function F(θ, φ) based at least partially on the respective measured color values. The system allows for a representation of color space of a surface at any azimuth and viewing angle.
