Gravure printing method

摘要

A gravure printing method is provided that includes: patterning a substrate to form a printing substrate having a recess portion and a convex portion; forming a first self-assembled monolayer on the surface of the recess portion; forming a second self-assembled monolayer on the surface of the convex portion; filling ink into the recess portion; and transferring the ink filled in the recess portion to a printing object substrate, wherein the first and second self-assembled monolayers respectively formed on the surfaces of the recess portion and the convex portion have different surface energies.

1. A gravure printing method comprising:
patterning a substrate to form a printing substrate having a recess portion and a convex portion; forming a first, hydrophilic, self-assembled monolayer on the surface of the recess portion; forming a second, hydrophobic, self-assembled monolayer on the surface of the convex portion; filling the recess portion with an ink, wherein the ink includes a polar solvent; and transferring the ink in the recess portion onto a printing object substrate, wherein an attractive force is generated between the first, hydrophilic, self-assembled monolayer and the polar solvent attracting the ink into the recess portion to fill the recess portion with the ink, and a repulsive force is generated between the second, hydrophobic, self-assembled monolayer and the polar solvent repelling the ink from the surface of the convex portion.
