Abstract
A method for forming a patterns includes applying ink onto an etching object layer; forming ink patterns on the etching object layer as a printing roll having convex patterns thereon rotates on the ink and removes portions of the ink which contact the convex portions of the printing roll, thereby forming ink patterns; and hardening the ink patterns.
Claims15
A method for forming a pattern, comprising:
- providing a printing roll having convex patterns thereon;
- applying an ink onto an etching object layer;
- and
- forming ink patterns on the etching object layer as the printing roll rotates on the ink with the convex patterns in contact with the ink,
- wherein the step of providing the printing roll having the convex patterns, comprises:
- providing a cylindrical roll having a blanket on its surface;
- applying an organic film to a surface of the blanket;
- providing a cliché having a plurality of convex patterns;
- forming organic patterns on a blanket surface which does not contact with the convex patterns by rotating the roll after contacting the organic film on the blanket surface with the cliché;
- and
- hardening the organic patterns.

- applying an ink onto an etching object layer;
- and
- forming ink patterns on the etching object layer as the printing roll rotates on the ink with the convex patterns in contact with the ink,
- wherein the step of providing the printing roll having the convex patterns, comprises:
- providing a cliché having a plurality of grooves;
- applying an organic material onto the cliché;
- filling the organic material into the grooves and simultaneously, removing the material remaining on the surface of the cliché by moving a doctor blade across the surface of the cliché;
- transferring the organic material filled in the grooves onto a surface of a cylindrical roll;
- and
- hardening organic patterns transferred onto the surface of the roll.
