An image inspection data creating device comprising: a target inspection page image data creating element which performs print rasterization on page data for creating a printed material, thereby creating target inspection page image data corresponding to print page image data to be printed by a printing machine, said page data being described by a page description language; an inspection page image data creating element which performs display rasterization on said page data differently from said print rasterization, thereby creating inspection page image data corresponding to display page image data to be displayed on a page data display device; a differential page image data creating element which creates differential page image data having a different image region between a target inspection page image and an inspection page image, by comparing said target inspection page image represented by said target inspection page image data and said inspection page image represented by said inspection page image data; and a differential page image attribute information creating element which creates differential page image attribute information identifying a cause of a differential page image, by acquiring attribute information of an image region (A1, A2, A3) of said target inspection page image and an image region (A1, A2, A4) of said inspection page image corresponding to said differential page image represented by said differential page image data, from said target inspection page image data and said inspection page image data; and a confirmation page image data creating element which creates confirmation page image data including said differential page image attribute information as a comment on said differential page image. a target inspection page image data creating element which performs print rasterization on page data for creating a printed material, thereby creating target inspection page image data corresponding to print page image data to be printed by a printing machine, said page data being described by a page description language; an inspection page image data creating element which performs display rasterization on said page data differently from said print rasterization, thereby creating inspection page image data corresponding to display page image data to be displayed on a page data display device; a differential page image data creating element which creates differential page image data having a different image region between a target inspection page image and an inspection page image, by comparing said target inspection page image represented by said target inspection page image data and said inspection page image represented by said inspection page image data; and a differential page image attribute information creating element which creates differential page image attribute information identifying a cause of a differential page image, by acquiring attribute information of an image region (A1, A2, A3) of said target inspection page image and an image region (A1, A2, A4) of said inspection page image corresponding to said differential page image represented by said differential page image data, from said target inspection page image data and said inspection page image data; and a confirmation page image data creating element which creates confirmation page image data including said differential page image attribute information as a comment on said differential page image.
