METHOD OF PRINTING FINE PATTERNS BY INTAGLIO PRINTING AND PRINTING SYSTEM FOR PRINTING FINE PATTERNS BY INTAGLIO PRINTING

摘要

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 + 8 erg/cm2 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.
