Abstract
A method of enlarging a design possessed by a synthetic resin film includes a printing step of printing the design on the top side of the synthetic resin film, and an enlarging deformation step of providing a curved portion by stretching a prescribed surface of the synthetic resin film which includes a portion on which the design has been printed and curvingly deforming the prescribed surface in such a manner that the surface will protrude above the plane defined by the synthetic resin film. The design printed on the synthetic resin film beforehand in the printing step is printed in dimensions conforming to the rates of enlargement of points on the curved portion of the synthetic resin film. A portion of the design having a small rate of enlargement is printed at relatively large dimensions in comparison with other portions thereof and a portion of the design having a high rate of enlargement is printed at relatively small dimensions in comparison with other portions thereof.
