A compressed image, for which a desired SSIM value is obtained, is acquired when irreversible compression is performed. Specifically, a quadratic curve Gis defined. Next, a compression ratio Pis calculated. An image is irreversibly compressed at the compression ratio P, the compressed image is decoded and an SSIM value Sis calculated. If the calculated SSIM value Sis outside an allowable range of the target SSIM value, then the quadratic curve Gis corrected in such a manner that it will pass through an intersection Cbetween the compression ratio Pand the SSIM value S, whereby a quadratic curve Gis obtained.

Page description language data are imposed according to entered imposition information. The imposed page description language data are converted into raster-format data by an RIP process. Page data depending on a plurality of page areas are clipped from the raster-format data. The clipped page data are mapped onto respective model areas corresponding to the page areas on a determined three-dimensional shape model thereby to generate three-dimensional preview data of a print. A three-dimensional preview image of the print is displayed based on the three-dimensional preview data.
