Optically variable ink & Refraction change color ink ( screen type )
The ink displays two distinct colors depending on the angle the bill is viewed at. it displays one colour at one angle, and the other colour in another.
Optically variable inks (OVI) - Color-shifting inks reflect various wavelengths in white light differently, depending on the angle of incidence to the surface. An unaided eye will observe this effect as a change of color change while the viewing angle is changed. A color copier or scanner can copy a document only at one fixed angle relative to the card’s surface.
