Gloss, Colour, Brightness, Surface Testing

The gloss of a surface is perceived through its light reflection, with the impression varying depending on the viewing angle. To determine the gloss level, the reflected light is measured at different angles to objectively categorize it as "high gloss," "medium gloss," or "matte gloss" and express it numerically. Since color and brightness are perceived subjectively and can be difficult to communicate, modern color measurement enables precise capture of color data for control and formulation. Since gloss can affect the color perception, simultaneous measurement of gloss and brightness is often useful.
