PROBLEM TO BE SOLVED: To obtain a printed matter which undergone the inexpensive and satisfactory sharpness processing. SOLUTION: A mask size correction parameter, a grayness correction parameter gS and an edge emphasis gain correction parameter f(u) are prepared for every output device and previously stored in a correction parameter memory 100. These parameters can obtain the images equivalent to each other with no dependence on the display characteristic of every output device. When an operator selects one of output devices, the sharpness processing is carried out based on the correction parameter corresponding to the selected output device. The sharpness processing result is outputted to the selected output device. Thus, the sharpness processing result is outputted to the optional one of a monitor 70, a monochromatic printer 90 and a color printer 91 and confirmed there. Then a print original plate can be produced by a film plotter 92. |
