2. Description of the Related Art An original picture of a painting such as an oil painting has unevenness of paint on the surface, and it is desired to reproduce not only the pattern but also the unevenness of the surface when reproducing the oil painting. Various attempts have been made to reproduce the uneven pattern of the original image (original). Then, as a reproduction of this uneven pattern, a cross-linking reactive liquid resin such as an unsaturated polyester resin is applied on a printing paper on which a pattern is printed, and a pressing die in which the uneven pattern of the original image is molded is overlaid and heat-molded. There is also known a method of forming a pattern, and a method of vacuum forming a synthetic paper on which a design pattern is printed in accordance with a mold.

[0003]

However, in the former method described above, since the pressing die has a reinforcing material layer such as a gauze or a stencil, it lacks transparency. There is a problem that it is difficult to register with the press die and misregistration easily occurs, and it is difficult to align the concave-convex pattern of the press die with the printed pattern pattern of the printing paper, that is, it is difficult to synchronize the printed picture with the concave-convex pattern. In addition, in this method, it is difficult to faithfully reproduce the color, density, and gloss of the original image because the resin is laminated on the printed surface of the pattern even as a completed duplicate image. The sharpness of the picture pattern was not sufficient.

Even in the latter method, since the synthetic paper is opaque, the above-mentioned problems occur when the synthetic paper is fitted to the mold, and it is difficult to accurately synchronize the printed picture and the uneven pattern. Furthermore, since the area of the synthetic paper is enlarged too much in correspondence with the unevenness due to the vacuum forming, there arises a problem that the density of the printing ink becomes thin and the pattern pattern is destroyed.
The present invention has been made in view of the above problems, and it is possible to accurately express a picture pattern in synchronization with a concavo-convex pattern, to faithfully express the color, density, and gloss of an original, and to duplicate the work. It is an object of the present invention to provide a method of copying a manuscript that can be easily performed and a duplicate.

Silicone rubber (for example, KE-1300TRTV manufactured by Shin-Etsu Chemical Co., Ltd.) 13a is evenly applied to a thickness of about 0.1 to 2.0 mm so as to prevent air bubbles from mixing on the surface of No. 0 and semi-cured or cured, and then this silicone is used. The rubber 13a is covered with a reinforcing material 14 such as a polyester fiber gauze (about 25 to 100 mesh) or a stencil, and the reinforcing material 14 is further covered with the silicone rubber 13b of the same grade as the silicone rubber 13a (hereinafter, 13a and 13b). Is represented by 13). Then, as shown in FIG. 1b, after the silicone rubber 13b is cured, the silicone rubber 13 integrated with the reinforcing material 14 is peeled off, and the pressing die 1 is used.
Used as 1. The pressing die 11 is provided on one surface with a concavo-convex pattern 11a whose concavities and convexities are opposite to the concavo-convex pattern 72a on the surface of the oil painting 70.

In the process for producing the uneven plate, first, the cardboard,
Metal plate such as MDF, plywood, particle board and aluminum plate, inorganic plate such as calcareous board, gypsum board, stone material,
A primer layer (not shown) made of a polyol resin such as a saturated polyester resin or an acrylic ester resin is formed on a base material 21 such as an acrylic plate or a synthetic resin plate such as an unsaturated polyester resin. Next, a transparent cross-linking reactive liquid resin 22, for example, a liquid resin such as an unsaturated polyester resin or an epoxy resin is poured on the primer layer, and the pressing die 11 is covered on the liquid resin 22 (see FIG. 2).
