PROBLEM TO BE SOLVED: To change the gloss of the specific part of an image formed on a prepress color proof with a surprinting method, for making the expression of a print effective by using a varnished film provided with an adhesive transparent resin layer including a transparent matting agent and a transparent photoreceptive layer. SOLUTION: The varnished film constituted in such a manner that the adhesive transparent resin layer including the transparent matting agent, being peelable from a transparent substrate and the transparent photoreceptive layer are laminated on the substrate is used. Then, a formed matte surface image is formed on the prepress color proof formed by the surprinting method, to obtain a color proof where the surface gloss of the specific part of the image is adjusted. In other words, when the varnished film is exposed with the image and developed, in an unexposed part, the photoreceptive layer is removed and the adhesive transparent resin layer including the transparent matting agent is exposed, so that the gloss of the unexposed part is reduced. Therefore, the difference in glossiness between an exposed part and the unexposed part is great and the image excellent in contrast can be obtained.
