Abstract

A printing device system comprises a printing roller that has a blanket adhered to an outer surface thereof. The printing device system further comprises a drying device that dries the blanket of the printing roller.

Claims (18)

1. A patterning method comprising:

moving a printing nozzle to the inside of a chamber through a first inlet, and supplying a pattern material to a blanket adhered to a printing roller by the printing nozzle;

moving the printing roller to the outside of the chamber through a second inlet;

rotating the printing roller on a cliché plate that has a projection so as to transfer some pattern material onto the projection of the cliché plate, and so as to leave the remaining part of the pattern material as a predetermined form on the printing roller;

rotating the printing roller on a substrate, to transfer the predetermined form of the pattern material to the substrate;

moving the printing roller to the inside of the chamber, and drying the blanket of the printing roller;

wherein the process for drying the blanket is performed in the cylinder; and

controlling a pressure inside the chamber after drying the blanket of the printing roller.

2. The method of claim 1 , wherein the process of drying the blanket is performed by a vacuum suction part.

3. The method of claim 2 , wherein the vacuum suction part is used in state of room-temperature air.

4. The method of claim 2 , wherein the vacuum suction part includes a plurality of holes that sucks air.

5. The method of claim 2 , wherein the vacuum suction part includes at least one slit that sucks air.

6. The method of claim 2 , wherein the vacuum suction part includes a temperature controller.

7. The method of claim 1 , wherein the process of controlling the pressure inside the chamber comprises supplying air to the inside of the chamber through a ventilator connected with the chamber.

8. The method of claim 1 , further comprising controlling a gap between the printing roller and a drying device that dries the blanket by a hydraulic device, the hydraulic device having one end connected with the chamber and the other end connected with the drying device.

9. The method of claim 1 , further comprising:

cleaning the cliché plate.

10. The method of claim 9 , wherein the process of cleaning the cliché plate and the process of drying the blanket are performed at the same time.
