Which Printer is best for pre-embossed paper

Hi all,
My institution needs to print some certificates of honor and we will need a printer that can print on pre-embossed cards without damaging the embossed material (foils seal with ribbons). Also, we want ink that is permanent and does not smear nor fade with time.
We are thinking of a flatbed (UV) printer but not sure of the ink longevity of those printers on the market.
Any recommendations?
