Abstract

Se codifica un substrato capaz de recibir y retener un dibujo de manera qua maximize la cantidad de informacion explorable que puede ser almacenada en unárea, y/o que proporcione una característica efectiva de seguridad. Se dibuja un primer codigo de identificacion legible mecánicamente (por ejemplo codigo de barras) sobre un área predeterminada del substrato, y que es opaca a un primer rango predeterminado de longitud de onda de energía electromagnética (por ejemplo la region de luz infrarroja. Se aplica una capa sobrepuesta sobre y cubriendo por lo menos parcialmente el primer codigo. La capa sobrepuesta es transparente al primer rango de longitud de onda y opaca a un segundo rango de longitud de onda (por ejemplo el espectro de luz visible). La capa sobrepuesta puede ser un bloque de seguridad el cual substancialmente cubre totalmente el primer codigo, o puede ser un segundo codigo de barras (o codigos adicionales) el cual es transparente al segundo rango. Los codigos pueden ser leidos por pases multiples de diferentes cabezas exploradas por movimiento relativo entre las cabezas y el substrato, o por un explorador en el cual la primer y segunda (o más) cabezas exploradoras diferentes se monten juntas de manera que sobre un substrato puedan leerse al mismo tiempo dos codigos de barras de diferentes rangos de longitud de onda.
