Latent Image

Latent image – is a security feature based on the optical effect under light produced by a special arrangement of plastic lines printed by intaglio technique. The picture becomes visible only when the note is held at the eye level in a horizontal position against a source of light. On the front of the note, the effect produces a dark or light picture of the abbreviation “Sk” of the Slovak currency unit, while on the back of the note, a picture of an eight-pointed star appears (on 5000 Sk banknote only).
