FIELD: printing equipment.
SUBSTANCE: marking for the substrate is proposed. Marking comprises at least one luminescent substance (a) and at least one material (b) based on a chiral liquid crystal polymer (CLCP). Wavelength range of the reflection waves overlaps at least part of the luminescence wavelength range (a). At least a portion of the luminescent substance (a) is disposed under the chiral fatty crystal polymer material (b).
EFFECT: marking containing the chiral liquid crystal polymer and the luminescent substance has been proposed.
