Abstract:
A method for manufacturing a glass cliché using laser etching includes a dipping step for dipping a glass cliché, which will be etched, into an etching solution, a patterning step for irradiating laser to the glass cliché dipped in the etching solution to form a pattern therein, and a washing step for washing the patterned glass cliché. This method allows making a cliché with a high aspect ratio and fine line widths in comparison to a conventional cliché manufacturing method using photoresist for etching, and also ensures more efficient energy consumption and higher etching efficiency rather than an etching method using laser only.
