the ink in coating 1 is cured under uv illumination permanently locking the orientation of the reflective color shifting flakes a second coating 2 is applied to form a third zone of 100 mm 2 located in between said first two zones using the same ink composition this second coating while still wet on the substrate is subjected to a magnetic field generated by said magnet located 3 mm above the surface of the substrate on the same side as the coating 2 thus creating a positively curved reflective surface according to the present invention with the flake like pigments oriented said zone reflects light in such a way that it visually resembles the internal surface of a hollow metallic cylinder said second coating is cured under ultraviolet illumination permanently locking the orientation of the reflective flakes example 1 shows a conspicuous visual effect characterized by a downward movement of the reflections emanating from the two zones in coating 1 accompanied by a simultaneous upward movement of the reflection emanating from the single zone in coating 2 as the print is tilted backwards here tilting backwards means rotating the printed substrate about an axis located in the plane of the substrate passing through all 3 printed zones so that the top of the substrate moves away from the observer whilst the bottom of the substrate moves toward the observer a first coating 1 is applied in the form of two square zones of 100 mm.
