PURPOSE: To guarantee the quality of printed matter by improving the visibility of mask data and shortening the time for its recognition, and also improving the accuracy of outline extraction. CONSTITUTION: A mask data coloring means 4 sets color information in a clipping area or clipping area of the mask data to generate colored mask data and a superimposed image generating means 4 superimposes image data and the colored mask data on the basis of the transmissivity of the set area of the color information of the colored mask data to generate superposed image data; and a display processing means 4 displays the superimposed image data generated by the superimposed image generating means and a transmissivity varying means varies the transmissivity of the superimposed image generating means 4. |
