[Working Principles]
More than ten different kinds of rare earth material are added to various substances of certain proportions, which are then sintered with different temperature and duration to get sintered compact stuff. The sintered stuff will be ground into powder with certain size and is used as the base material to be added to printing ink and other substances in specific formula so that anti-counterfeit marks will be produced by printing such substances on words, numbers, patterns or designated positions on the outer packing of commodities through original printing process.
