A control section 11 of an image data generation apparatus 1 of a thermal transfer recording apparatus S performs resolution conversion processing, gradation conversion processing, CMYK separation processing, contour expansion processing, image sift processing, dot processing, and image reverse shift processing for entered image data 5 stored in an image memory 33 of a storage section 12. The control section 11 sends the produced image data to a printing section 2, prints it on an intermediate transfer medium, and transfers it onto a polycarbonate film or the like. Through contour expansion processing, contours of color images masked by a black background are expanded by numbers of pixels which differ among the colors, and masked by the black background.
