Abstract
The emission of light (6) of a controlled wavelength is directed towards a region of the document to be checked. The reflected and refracted light on the light sensor (2) is collected by optical focusing system and the transmission of the signal generated in the light sensor is sent to an interpretation and validation microprocessor. An INDEPENDENT claim is also included for a method of identifying substrates bearing graphic matter.
