Abstract

La presente invención se refiere a un marcado de material de cristal líquido polimérico con unas determinadas características ópticas que permiten su autenticación y lectura mediante una máquina y su autenticación por el ojo humano. El marcado se aplica en un objeto, mercancía o artículo mediante un proceso de impresión de información variable. El marcado tiene la forma de indicios que representan un código único que permite tanto una autenticación fácil por el ojo humano como un seguimiento y rastreo seguros del objeto, mercancía o artículo marcado a lo largo de todo su ciclo de vida.
