Abstract:
A printing plate and method for fabricating the same is disclosed. A metal layer is first formed on a glass substrate. The metal layer is then patterned in a predetermined shape. The glass substrate is next etched to a predetermined depth using the patterned metal layer as a mask and the metal layer removed. If necessary, additional metal layers have the same or different patterns may be formed on the glass substrate and the glass substrate etched after each metal layer is formed thereon until a desired etching depth in the glass is achieved.
