Abstract

PARA PREPARAR EXTRACTOS DE COLOR SE MUESTREA PUNTUALMENTE UN MODELO (3), DE FORMA POLICROMATICA, POR EJEMPLO, TRICROMATICA, PARA OBTENER LOS VALORES DE LAS SEÑALES DE COLOR, LOS CUALES SE UTILIZAN PARA LA CREACION DE LOS EXTRACTOS DE COLOR. PARA ESTO, SE SELECCIONA UN DETERMINADO NUMERO DE LOS VALORES DE SEÑALES DE COLOR QUE APARECEN CON MAYOR FRECUENCIA. DESPUES SE LLENA EL ESPACIO DE COLORES (RGB) CON ESTOS VALORES DE SEÑALES DE COLOR MAS FRECUENTE PARA OBTENER UN ESPACIO CORRECTOR DEL COLOR. EL MODELO (3) SE MUESTREA DESPUES, POR SEGUNDA VEZ, PUNTUALMENTE DE FORMA POLICROMATICA O TRICROMATICA, SUSTITUYENDOSE LOS VALORES DE SEÑAL DE COLOR ASI OBTENIDOS POR LOS VALORES DE SEÑAL DE COLOR QUE, EN EL ESPACIO CORRECTOR DE COLOR, SE ENCUENTRAN EN EL MISMO LUGAR. CON EL INVENTO PUEDEN REPRODUCIRSE, DE FORMA ELECTRONICA Y CON EL COLOR EXACTO, UN MODELO CON RELATIVAMENTE POCOS COLORES Y NECESITANDO SOLO UN REDUCIDO DEPOSITO.
