Sažetak

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.
