    • PROBLEM TO BE SOLVED: To manufacture a printed matter with a curved face which can deal with demand for a small lot and a variety of grades per lot, rapidly and at a low cost by laminating a pictorial image layer to be printed under an on-demand system, on one of the faces of a supporting film which swells in a specific solvent. SOLUTION: The on-demand system is a printing method by which printing is performed without the use of a printing plate. In detail, an ink jet system, an electronic photography system, a heat fusion-type or a dye sublimation-type heat transfer system and the like are available. After printing an image on a supporting film 1 in ink A using an ink jet printer 2, an image layer 3 which constitutes a pictorial pattern by a drying process is formed to obtain the transfer film 4 for printing a curved face. The supporting film 1 is preferably of such a type that it swells sufficiently in a solvent during transfer in a curl fit printing process and displays the suitability for multicolor printing and transfer printing properties and also has such a property as to stubbornly adhere to the surface of a printed matter with a curved face. Thus it is possible to manufacture the printed matter with a curved face in a short time and at a low cost, compared to the case with the use of a conventional transfer film for printing a curved face by gravure printing which requires a printing plate.
