OPTICAL DEVICE HAVING AN ILLUSIVE OPTICAL EFFECT AND METHOD OF FABRICATION

摘要

A method is provided for manufacturing an image on a substrate, wherein the image includes an indicia and a frame. The method includes covering at least a portion the substrate with a carrier comprising magnetically alignable flakes, aligning the magnetically alignable flakes with a magnetic field of a magnetic assembly comprising a metal plate with an opening, and solidifying the carrier. The frame is formed at an edge of the opening and the indicia is visible within the frame. The magnetic assembly includes two magnets disposed so that the North pole of one magnet and the South pole of another magnet are proximate to the metal plate at opposite sides of the opening.
