AN INK PRINTING APPARATUS FOR COMPENSATING MIS-ALIGNMENT OF PATTERNS CAUSED BY VARIATION OF A SUBSTRATE AND A PATTERNING METHOD USING THEREOF

摘要

A method for patterning includes filling ink in a recess of a cliché corresponding to a position of a pattern which will be formed, transferring the ink onto a surface of a transfer roll by rotating the transfer roll while the transfer roll is contacted to the cliché, detecting variation of the substrate by calculating the area of the substrate on which the ink is transferred, calculating moving speed of the substrate on a basis of the detected variation, and re-transferring the ink on the surface of the transfer roll onto the substrate by rotating the transfer roll when the transfer roll is contacted to the substrate while moving the substrate at the calculated moving speed.
