Abstract (en)
[origin: EP1839893A1] A method of printing on a metal surface includes steps of forming a plurality of macropores (110) on at least a portion of a metal surface. A plurality of micropores (112) are formed within and adjacent to the macropores. The metal surface is cleaned, and a first ink having a first color is applied to the macropores and micropores to form at least one image (114) on the metal surface. Preferably, the ink is applied using an inkjet printer. The ink is dried. A second ink (120) having a second color may also be applied to the metal surface and then dried. Additional inks may also be applied. A lacquer top coat (122) may be applied to the metal surface on top of the first ink (and additional inks, if provided). Preferably, the metal surface is part of a coin (100).
