Method of printing fine patterns by intaglio printing and printing system for printing fine patterns by intaglio printing

A printing system of fine patterns, comprising:

• a printing roller having an outer circumference with an intaglio pattern and coating a substrate with a fine pattern printing ink filled in an intagliated portion of the outer circumference while rotating on a central axis;
• an ink supplying unit for supplying and applying the ink to the outer circumference of the printing roller;
• an ink removing belt rotating in close contact with an embossed portion of the outer circumference of the printing roller so as to remove an ink applied to the embossed portion of the outer circumference of the printing roller and having a polymer resin or an organic compound with a surface energy ranging from <a surface energy of the ink−2 erg/cm2> to <the surface energy of the ink+8 erg/cm2;
• and
• a belt rotating unit for successively rotating the ink removing belt.
