Abstract

Procedimiento y matriz de medición de la gama cromática de un recubrimiento gonioaparente.#La invención describe un procedimiento para medir y representar los colores que adquiere un recubrimiento gonioaparente según los ángulos de irradiación y observación para cualquier tipo de contenido espectral de una fuente de luz, estandarizada o no. El procedimiento comprende los pasos de: medir el factor de reflectancia para varias combinaciones de valores regularmente espaciados de ángulo de irradiación ({ze}{sub,i}) y ángulo de observación ({ze}{sub,s}); calcular los valores triestímulo XYZ correspondientes a un iluminante y un observador normalizados a partir del factor de reflectancia obtenido en el paso anterior; calcular los valores RGB o CMYK a partir de los valores triestímulo XYZ obtenidos en el paso anterior; y representar los valores RGB o CMYK de cada combinación de ángulo incidente ({ze}{sub,i}) y ángulo de observación ({ze}{sub,s}) en las celdas de una matriz. La invención también describe la matriz obtenida por dicho procedimiento.
