Abstract: A method of printing fine patterns prints a fine pattern on a substrate using an elastic mold with an intaglio pattern. This method includes applying a fine pattern printing ink to a surface of a patterned elastic mold; removing the ink applied to an embossed portion of the elastic mold by closely adhering an ink removing unit having a polymer resin or an organic compound with a surface energy from <a surface energy of the ink?2 erg/cm2> to <the surface energy of the ink+erg/cm> to the surface of the elastic mold and then detaching the ink removing unit therefrom; and closely adhering the elastic mold to a substrate to transcribe the printing ink thereto. This method allows forming a fine pattern with good quality since the ink applied to the embossed portion of the elastic mold may be effectively removed during a gravure process.

The step (S2) may be performed in a way of closely adhering a surface of an ink removing unit having a surface energy from <a surface energy of the ink?2 erg/cm2> to <the surface energy of the ink+8 erg/cm2> to the embossed portion of the elastic mold and then taking away the ink removing unit from the embossed portion. This method allows forming a black matrix in a simple and economic way by applying the gravure process.
