Abstract

Un método de medición del nivel de defecto de una región de un sustrato para un documento de seguridad, donde el nivel de defecto se asocia con la transparencia reducida de la región del sustrato, el método incluye las etapas de: toma de imágenes digitales en la región para crear una imagen digital, la imagen digital que contiene datos de intensidad de la luz; y análisis de la imagen digital que incluyen: calcular una medida estadística de los datos de intensidad de la luz en la región; y asignar una calificación de defecto a la región sobre la base de la medición estadística de los datos de intensidad de la luz en la región.
