Thus, the rare earth anti-counterfeiting inkpad can be customized, or produced by means of standardized, generalized, serialized, and industrialized production. Meanwhile, both the products manufactured by manufacturing companies and the customized seal impressions are traceable, so that it can be widely applicable to the anti- counterfeiting tracing of the inkpad and its derivatives, without damaging the sample. Furthermore, the unique authentication can be accomplished through comparing the spectrums.

With the rapid development of electronic seal reproduction technology, the original traceability authentication of seal images, especially the authentication of seal imprint of high-quality fake calligraphy and painting works, has quit the stage. The traceability authentication of seal imprint produced by means of electronic seal reproduction is conducted by authenticating universal images of seal. Thus, it is impossible to make a conclusion related to traceability. Till now, relevant information about the use and research of anti-counterfeiting inkpad, which can test the seal by utilizing the spectral lines of inkpad and based upon adopting the method of spectral traceability, has not been reported. Summary of the Present Invention The present invention is characterized in that mixing rare earth powder, rare earth powder oxides, rare earth powder reactants, and the combination of such rare earth powder, rare earth powder oxides, and rare earth powder reactants according to certain ratio to prepare the spectrum traceable material, and then testing and recording the spectral lines of the spectrum traceable material, the inkpad, the rare earth anti-counterfeiting inkpad containing the spectrum traceable material, the carrier for sealing with the inkpad, the seal, and the carrier for sealing subjected to ageing treatment by means of spectroscopic test, after that, comparing the aforesaid spectral lines, and thus the consistency of typical spectral lines can be traced by means of direct-reading spectrometry.
The present invention is characterized in that:
1. Mixing rare earth powder, rare earth powder oxides, rare earth powder reactants, and the combination of such rare earth powder, rare earth powder oxides, and rare earth powder reactants according to certain ratio to prepare the spectrum traceable material source.

The process control showed in the figure is as follows: Mix materials physically. Adopt the universal stirring method for solid-liquid mixtures, which shall meet a criterion that all typical spectral lines can be obtained for the sampling test. Test 10 spectral lines, which shall meet a criterion that all of them are consistent through visual inspection.
