PURPOSE:To efficiently extract only vector data required for a printing process by providing a noise eliminating device for a minute and closed vector data loop which is converted, while referring to knowledge information which is recorded in a knowledge information memory. CONSTITUTION:The main point of a variation on a binary fine line is retrieved by a direction code, and original vector data 21 is corrected automatically to corrected vector data 22. Subsequently, when a noise eliminating device 5i retrieves vector data in accordance with knowledge information of an image memory 4 and a noise elimination rule, noise data 16 can be erased automatically. In such a way, noise elimination vector data 18 is generated. In such a state, a layout scanner 8 executes an access to the image memory 4, while referring to the data which is generated by the device 5i, extracts only color image data corresponding to the inside of the data 18, and executes an exposure output to each block with respect to a printing film block 9 which is set to an output drum. |
