FLUORESCENT INFORMATION LABEL AND METHODS OF MAKING SAID LABEL Russian patent published in 2013 - IPC G06K1/12 G06K7/10 

FIELD: physics.

SUBSTANCE: invention is aimed at making a symbolic label for direct application, for example a two-dimensional label, in which information elements, for example cavities of a needle-impact label or laser-treated regions during laser engraving, using techniques described in the invention, are filled with fluorescent dyes which absorb radiation at wavelengths, for example, either below the shortwave transmission edge of a reader filter, for example, in the 250-600 nm range, and radiating in the wavelength range of the bandwidth of a receiving reader channel, for example 600-700 nm, or absorbing radiation at wavelengths longer than the long-wave transmission edge of a reader filter, for example in the 700 nm-10 mcm range, and radiating in the wavelength range of the bandwidth of an input reader filter, for example 600-700 nm.

EFFECT: providing high image contrast, image quality which does not depend on reflecting and microrelief properties of a surface, makes reading easier, and also enabling reading of labels with scanners designed to read ordinary labels.
