PROBLEM TO BE SOLVED: To solve the problem, that while release paper can be eliminated by a method using a heat-sensitive adhesive in place of a pressure-sensitive adhesive in order to reduce an environmental load, a cover film is preheated in a conventional technique causing a curl easy to occur in a laminated sheet after the adhesion to a printing base material, with limited use now. SOLUTION: The cover film and the printing base material are heated and pressed at the same time to be thereby adhered to each other, and subsequently held to an adhesive temperature or close to the temperature for a definite time for more reduction of the curling of the laminated sheet.
