Near-infrared spectroscopy and hidden graphics applied in printing security documents in the offset technique
The method of mixing pigments for the printing technology is expanded with the addition of dual states in security graphics. Near- infrared spectroscopy of colorants used in the offset technique has brought about the concept of targeted design by a selective use of colorants that are visible in the visible region of the electromagnetic spectrum.
