Abstract
By flow-melting low-melting point electroplated metal structures, each corresponding to a white-manifesting region of the embossing master, any originally re-entrant shaped structure becomes non-re-entrant. Further, the flow-melting provides a brighter white color capability for the filter embossed in a thermoplastic film.
