Abstract
A printing device and a printing method using the same is disclosed. An air pocket is formed in a cliché stage to prevent a cleaning solution from permeating into a space between the cliché stage and a cliché plate, thereby preventing a lower surface of the cliché plate from being contaminated. The printing device comprises a cliché stage for fixation of a cliché plate, a plurality of vacuum holes disposed in the cliché stage for providing a vacuum to fix of the cliché plate to the cliché stage; and an air pocket surrounding the plurality of vacuum holes for providing air to minimize permeation of a cleaning solution into a space between the cliché plate and the cliché stage.
Claims9
A printing device comprising:
- a cliché stage for fixation of a cliché plate;
- a plurality of vacuum holes disposed in the cliché stage for providing a vacuum to fix the cliché plate to the cliché stage;
- and
- an air pocket surrounding the plurality of vacuum holes for providing air to minimize permeation of a cleaning solution into a space between the cliché plate and the cliché stage.
A printing method comprising:
- fixing a cliché plate having concave or convex portions to a stage including a plurality of vacuum holes and an air pocket surrounding the vacuum holes;
- coating a pattern material on an outer surface of a printing roller;
- rotating the printing roller on the cliché plate, thereby printing a first portion of the pattern material on the convex portions of the cliché plate and retaining a second portion of the pattern material on the outer surface of the printing roller;
- rotating the printing roller on a substrate, thereby transferring the second portion of the pattern material from the printing roller to the substrate;
- and
- cleaning the cliché plate, thereby removing the first portion of the pattern material from the cliché plate, wherein the cleaning comprises supplying air to an air pocket.
