Abstract:
A method for printing a fine pattern is provided to make the uniform width, external circumference, size, and shape of the fine pattern by preventing an ink separation from a printing region of a partition layer. A substrate(11) is prepared. A printing region is formed on the substrate by a partition layer(13). An ink(I) is transferred to the printing region to print a fine pattern(5). Soft-hardening is performed on the fine pattern. A height of the soft-hardened fine pattern is uniformed. The fine pattern whose height is uniformed is hardened. The substrate and an inner wall of the partition layer corresponding to the printing region have hydrophile property with respect to the ink. A non-printing region except for the printing region has a hydrophobic property with respect to the ink. The fine pattern is printed through a screen print, a grabia print, a flexo print, a pad print, and an ink jet print.
