OVI printed features for dynamic color changes

OVI printed features produce dynamic color changes on a banknote when it is tilted.

OVI printed features are generated using special tiny pigment pads in transparent ink varnish which change color depending on the light’s angle of incidence. When viewed straight on a design may appear in magenta, but as the banknote is tilted the color (SICPA OVI) shifts to green.
