Abstract

A process for the recognition of elements marked with OVItm (Optical Variable Ink) comprising the following steps: - production of a ray of polarised light by the use of a first polarising filter (13) on a source of light; - exposure of the part of the document or banknote marked with OVItm type inks to the ray of polarised light; - additional filtering of the light reflected by the document or the banknote by means of a second polarising filter (14) placed at an appropriate reciprocal angle with respect to the degree of polarisation of the incident light; - detection of the variation in luminescence.
