Abstract
A method and an apparatus for cleaning a printing plate for fabricating an alignment film in which the printing plate is dipped into an internal container filled with a solvent and a predetermined vibration is transmitted to the printing plate so as to remove a polyimide remaining at the printing plate. In addition, the printing plate is loaded into a heater tank and baked at a high temperature with an injected gas, to thereby completely remove solvent residuals at the printing plate, completely cleaning the printing plate and preventing solvent residuals from solidifying.
