METHOD FOR PRINTING LOGOS INVISIBLE TO DAYLIGHT AND VISIBLE TO ULTRAVIOLET LIGHT SPECTRUM, IN TEXTILES AND GARMENTS, EITHER IN SYNTHETIC OR NATURAL FIBERS.

摘要

The present method is useful for making printed logos invisible to daylight and visible to ultraviolet light spectrum in garment and textiles. The ultraviolet inks are important safety measures used to authenticate valuable documents such as banknotes and bank credit cards; these are known as invisible inks. There are ultraviolet inks, which are commercialized as markers or ink containers which are degraded with washing and drying. The inks with a high content of solids with fluorescence resist washing and drying but are not invisible. The method of the present invention turn the printed logos into invisible to daylight and visible to the ultraviolet light spectrum in garments and textiles, these are resistant to washing and drying processes, thus the invisible logos may be commercialized integral with the garment, which may have different uses, above all in safety printings against the non-authorized reproduction and piracy.
