ABSTRACT:
In a digital printing process employing a CTP device14, hues can easily be changed in a process of generating printing plates without going back to a prior process. A plurality of gradation conversion curves whose gradation characteristics are different stepwise from each other, which are stored in a gradation conversion curve saving unit22, are displayed on a display unit36. The user selects a desired of the displayed gradation conversion curves with respect to at least one color element with a keyboard/mouse34. The selected gradation conversion curve is set in an LUT converter26. Input image data G can easily be converted into output image data Ga by converting the gradations of the input image data G according to the gradation conversion curve set in the LUT converter26. The image data Ga is converted by a binarizing unit30into binary image data H, which is supplied to the CTP device14. The CTP device14outputs printing plates each bearing a binary image represented by the binary image data H.
