Abstract: An original plate manufacturing method includes preparing first design data and second design data from a predetermined pattern to be formed on a target object. The first design data corresponds to a first design pattern, and the second design data corresponds to a second design pattern. The first and second design patterns are complementary portions of the predetermined pattern. The first design pattern is then formed on the target object based on the first design data. An inspection is performed on the target object on which the first design pattern has been formed. Third design data is generated based on a result of the inspection. The second design data is then adjusted based on the third design data to generate corrected second design data. The target object is then patterned again based on the corrected second design data.
