Abstract (en)
The procedure, for use with banknotes or other documents (10), consists of applying a security sign (100) using two different substances with pigments that generate luminscent radiation at different spectral frequencies in response to excitation radiation (210) centred around a wavelength of about 370 nm. The first substance generates luminescent radiation with a broad frequency range, while the second one emits one or more rays outside the spectrum of the first. The emitted radiation (220, 221, 222) can be detected by a machine or the naked eye.
