Abstract: In a printed article, pigment flakes are magnetically aligned so as to form curved patterns in a plurality of cross-sections normal a continuous imaginary line, wherein radii of the curved patterns increase along the imaginary line from the first point to the second point. When light is incident upon the aligned pigment flakes from a light source, light reflected from the aligned pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the continuous imaginary line when the substrate is tilted with respect to the light source.

Abstract: A scanning laser having a wavelength compatible with a coating binder so as to cure it as the laser scans and irradiates the coating on a moving web. A system and method for curing flakes by providing a scanning laser which scans across a moving coated substrate in a magnetic field allows images to be formed as magnetically aligned flakes are cured into a fixed position. The images have regions of cured aligned flakes. The scanning laser cures the magnetically aligned flakes within it region it irradiates. Alternatively an array of lasers can be used wherein individual lasers can be switched on and off to fix irradiated coating as a moving web is moved at a high speed.

Abstract: 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.
