Abstract: A method for high resolution ink-jet print using a pre-patterned substrate employs an ink-jet printing device including an ink-jet head for discharging conductive ink droplets and a driving stage for supporting a substrate to which the conductive ink droplets are hit, to draw a fine line width pattern on the substrate. The method includes (A) forming a stripe pattern with repeated stripes on a substrate surface on which a fine line width pattern will be formed, thereby preparing a pre-patterned substrate; (B) loading the substrate to the ink-jet printing device; and (C) injecting conductive ink droplets to a substrate region where the stripe pattern is formed. An equivalent interval (d) of the stripe pattern and a fine line width (D) of the drawn fine line width pattern satisfy a relation of d<<D, and the hit ink droplets are flowed in an anisotropic form within the region.
