Title:
BRONZE RED PRINTER TONER EMPLOYING RARE EARTH SPECTROSCOPY TRACING
Document Type and Number:
WIPO Patent Application WO/2021/134812
Kind Code:
A1
Abstract:
A bronze red printer toner employing rare earth spectroscopy tracing. Yttrium oxide (1), a yttrium oxide reagent (2), other rare earth oxides (3) and a reagent powder (4) are mixed to form a spectroscopy tracing material which is mixed with a printer toner (6). Proportions of the above components are recorded. A spectral line of the mixed printing material is tested and recorded. Printing is performed on a carrier, and a spectral line of the print carrier is tested and recorded. After the carrier has undergone an aging process, a spectral line of the printing material is tested again. The invention enables standardized, generalized, serialized and industrialized production of the bronze red printer toner employing rare earth spectroscopy tracing, such that products of a manufacturer are traceable, and customized printed products of a user are traceable. The invention can be widely applied to anti-counterfeiting and tracing measures for printed products and derivative products thereof. Since spectroscopy comparison is employed to perform uniqueness verification, no damage will be caused to samples.
