FIELD: printing.
SUBSTANCE: 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 curved patterns increase along imaginary line from first point to second point.
EFFECT: when light is incident upon aligned pigment flakes from a light source, light reflected from aligned pattern forms a bright image which appears to gradually change its shape and move from one side of continuous imaginary line to another side of continuous imaginary line when substrate is tilted with respect to light source.
