Description

Technical Field

[0001] The present invention relates to Japanese painting reproductions, and more particularly, to Japanese painting reproductions manufactured by printing technology. The manufacturing method of this Japanese painting reproduction is also mentioned.

Background Art

[0002] Regarding paintings with artistic and historical value, while storing the original in a good environment to prevent deterioration, it is widely practiced to provide replicas for general display, sales, etc. From the perspective of enabling viewers to feel the texture and brushwork of the original, there is no doubt that replicas with a highly reproduced texture of the original are preferable, and Japanese paintings are no exception.

[0003] One of the characteristics of Japanese paintings is the use of mineral pigments. Since mineral pigments are formed by finely pulverizing ores and rocks, they produce a unique texture due to the luster and unevenness caused by the cleavage surfaces of fine gravel. In general printing, such luster and texture do not occur, so it can be said that one of the problems in replicating Japanese paintings is to create an appearance similar to these.

[0004] Several techniques for the purpose of reproducing the luster described above in Japanese painting replication are known. In Patent Document 1, after forming a replication print of a Japanese painting on a base material, a transparent adhesive is applied, synthetic resin powder is scattered, and then heated and melted. In Patent Document 2, a layer of white lead (gofun, a white pigment) is formed on the surface of Japanese paper, and a replication print is formed on the white lead layer by offset printing. Further, parts that should be particularly emphasized or parts that cannot be fully expressed by offset printing are formed by silk screen printing.

SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

[0006] Although the techniques described in Patent Document 1 and Patent Document 2 have certain effects, there is still room for improvement in terms of the reproduction of gloss at present. In addition, Patent Document 1 requires steps that are not common in general printing, such as spraying and heat-melting synthetic resin powder, and Patent Document 2 requires steps such as forming a mica layer, so there is also room for improvement in terms of manufacturing efficiency.

[0007] An object of the present invention is to provide a Japanese painting reproduction that can be easily produced and has a gloss closer to that of mineral pigments.

MEANS FOR SOLVING THE PROBLEMS

[0008] The first aspect of the present invention is a Japanese painting reproduction. This Japanese painting reproduction includes a Japanese paper layer, a printing layer formed on the Japanese paper layer, a binder, and mica, and includes a gloss adjustment layer formed on the printing layer.

[0009] The second aspect of the present invention is a method for manufacturing the Japanese painting reproduction according to the first aspect. In this manufacturing method, a printing layer is formed on the Japanese paper layer, and ink containing a resin or a resin precursor serving as a binder and mica is printed on at least a part of the printing layer, and the mass ratio of mica to the resin or the resin precursor is 0.1% or less, and the mica is fixed on the printing layer by the binder.

Embodiments for Carrying Out the Invention

[0012] An embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a view showing a Japanese painting reproduction (hereinafter simply referred to as "reproduction") 1 according to the present embodiment. The reproduction 1 is a reproduction of an original Japanese painting using a printing technique, and has a gloss similar to that of rock paint partially due to the structure described later.

[0013] FIG. 2 is a partial enlarged sectional view of the reproduction 1, showing the layer structure of the reproduction 1. The reproduction 1 includes a Japanese paper layer 10 serving as a base material, a printing layer 20 provided on the Japanese paper layer 10, and a gloss adjustment layer 30 formed on the printing layer.

[0014] There are no particular restrictions on the Japanese paper constituting the Japanese paper layer 10, and various known Japanese papers can be used. The printing layer 20 is a layer for reproducing the main elements such as the pattern and color of the original Japanese painting, and can be formed by various known printing techniques including inkjet. In recent years, although there is very high-quality inkjet printing, it is still not sufficient from the viewpoint of reproducing the texture of Japanese paintings.

[0015] The gloss adjustment layer 30 contains a binder mainly composed of a resin. Examples of the resin constituting the binder include various synthetic resins such as thermoplastic resins and curable resins. Examples of the thermoplastic resin include vinyl chloride-based resins. Examples of the curable resin include ultraviolet curable resins. The resin preferably has high transparency.

[0016] As shown in Fig. 2, the glitter 31 is disposed on the surface and inside of the gloss adjustment layer 30. Fig. 3 shows an enlarged view of the glitter 31. The glitter 31 has a structure in which a thin metal layer 31b is formed on a base material 31a made of synthetic resin. Examples of the material of the base material 31a include polyester resins such as polyethylene terephthalate (PET). Examples of the material of the metal layer 31b include aluminum, gold, silver, copper, etc., and it can be easily formed by vapor deposition or the like. Among these, aluminum is preferable. The metal layer 31b may contain components other than metals such as metal oxides. The metal layer 31b may be formed on one side or both sides of the base material 31a. The thickness of the metal layer 31b is generally 1 nm or more and 1000 nm or less, and preferably 5 nm or more and 100 nm or less from the viewpoints of texture expression and dispersibility. The glitter 31 produces a sparkling appearance depending on the viewing angle due to the metal layer 31b reflecting light, and this appearance mimics the gloss by the particles of the rock paint. The glitter 31 is fixed on the surface of the replica painting 1 by the binder of the gloss adjustment layer 30. However, since its posture is irregular, the sparkling appearance varies depending on the viewing angle. The glitter 31 may partially protrude from the surface or may be covered by the binder. From the viewpoint of scratch resistance, it is preferable that the binder covers the glitter 31.

[0017] An example of the manufacturing procedure of the replica painting 1 configured as described above will be described. First, as a preparatory work, print data for forming the print layer 20 is created. This setting can be performed, for example, according to the following procedure, but this is not essential and may be performed by other procedures. · Select a plurality of adjustment regions from the original imaging data · Create a color chart based on the adjustment regions and visual inspection of the original · Adjust the color tone of the print data based on the color chart to complete the print data

[0018] Next, the print layer 20 is formed on the Japanese paper layer 10 using the completed print data. Further, a gloss adjustment layer 30 including a metallic foil 31 is formed on the printing layer 20 using an ink. This ink contains a resin or a resin precursor and the metallic foil 31. The resin precursor is something that forms a resin by polymerization, such as a monomer or an oligomer. The ink may be one in which the resin or the resin precursor and the metallic foil 31 are diluted with a solvent so as to be easy to print. As the solvent, a known solvent such as a hydrophilic solvent or a hydrophobic solvent can be used according to the ink.

[0019] After the ink is printed, since the solvent soaks into or volatilizes from the Japanese paper layer 10, only the binder and the metallic foil 31 remain on the printing layer 20, and the metallic foil 31 is held on the printing layer 20 by the binder.

[0020] The amount of the metallic foil 31 in the ink is preferably 0.1% or less, more preferably 0.05% or less, by mass ratio of the resin or the resin precursor that serves as the binder. Inks containing metallic foils are widely used for various purposes. Usually, the content of the metallic foil is set to about 3% for the purpose of sufficiently producing the gloss by the metallic foil, and it rarely falls below 1%. The content rate in this embodiment is at most 1 / 60 or less of the content of the metallic foil in a general metallic foil ink, and is completely insufficient in view of the general purpose of using a metallic foil ink. However, it is extremely suitable for the purpose of the present invention of producing an appearance close to the gloss produced by a gouache. Since the metallic foil 31 has good dispersibility and dispersion stability in the ink, the metallic foil 31 does not aggregate in the completed gloss adjustment layer 30, and a gloss close to that of a gouache can be reproduced. Further, since the metallic foil 31 is hardly discolored when touched by air or hand, the gloss close to that of a gouache can be maintained.

[0021] Since the gloss adjustment layer 30 is formed by silk screen printing, the size of the lame 31 is set so that it can pass through the screen. It is preferable to set the planar dimension of the lame 31 to be within a square of 150 μm (0.15 mm) in size, as it will be approximately the same size as the fine pieces of ore that produce gloss with actual rock paint. A lame of such a size can pass through a commonly used screen of about 100 mesh to 80 mesh without problems. The planar shape of the lame 31 does not have to be a quadrilateral as shown in FIG. 3, and may be other polygons, a circle, an irregular shape, etc.

[0022] After applying the ink by printing, processing according to the ink, such as removing the solvent by heat drying and curing by irradiation with light such as ultraviolet rays or electron beams, completes the gloss adjustment layer 30. Although there is no particular limitation, it is preferably that the completed gloss adjustment layer 30 contains 2 to 30 lames 31 per 1 cm 2 in terms of appearance. When the number of lames 31 per 1 cm 2 is small, it is suitable for reproducing the gloss of a fine-grained rock paint or the gloss of a Japanese painting with less overlapping of the paint. When the number of lames 31 per 1 cm 2 is large, it is suitable for reproducing the gloss of a coarse-grained rock paint or the gloss of a Japanese painting with a large amount of overlapping of the paint. In the present invention, the number of lames 31 per 1 cm 2 is defined as the arithmetic mean value of three locations obtained by observing any three locations of the gloss adjustment layer 30 of the Japanese painting reproduction 1 visually or with a microscope and counting the number of lames 31 per 1 cm 2 In this way, the reproduction 1 is completed. In the completed reproduction 1, the reproduction of the pattern etc. by the printing layer 20 and the minute glow similar to the gloss of the rock paint by the lame 31 are combined, and a high-quality appearance is realized such that a texture close to the original can be felt.

[0023] ​As described above, the reproduced painting 1 according to this embodiment can be easily produced by a commonly used printing method, realizes a gloss closer to that of rock paint, and has extremely high reproducibility. Therefore, viewers can experience the texture of the original and obtain a high level of satisfaction, and it also becomes easier to conduct such exhibitions in parallel in many places.

[0024] In this embodiment, the thickness of the gloss adjustment layer 30 can be set as appropriate. However, if it is too thick, it may affect the color tone. Therefore, it is preferably 50 μm or less, and more preferably 20 μm or less. The thickness of the gloss adjustment layer 30 in the present invention can be measured by observing a cross-section prepared by embedding a fragment of the Japanese painting reproduction 1 in a photocurable resin and cutting it with an ultramicrotome using a scanning electron microscope (SEM). More specifically, the cross-section is observed in 6 fields of view using SEM, and it is defined as the arithmetic mean value of a total of 12 points consisting of the minimum and maximum film thickness sites in each field of view.

[0025] As described above, each embodiment of the present invention has been described. However, the specific configuration is not limited to this embodiment, and it also includes configuration changes, combinations, etc. within the scope that does not deviate from the gist of the present invention.

[0026] For example, the lame used in the present invention is not limited to those with a colorless base material, and may be a colored transparent one. The base material can be colored by coating with pigments, dyes, etc. The color of the base material when colored is not particularly limited, such as yellow, red, blue, etc., and these may be used in combination with the lame with a colorless base material. Among them, when the base material is colorless, it is preferable for reproducing the texture of rock paint. The thickness of the base material is generally 5 μm or more and 1000 μm or less, and from the viewpoints of dispersibility and fixing property, it is preferably 10 μm or more and 100 μm or less.

[0027] In addition, the gloss adjustment layer does not necessarily have to be provided over the entire surface of the replicated painting. As a white Japanese painting pigment, crushed shells may be used instead of rock pigment, in which case no gloss is produced. Therefore, for example, in an area where only such a white pigment is applied in the original, the gloss adjustment layer may not be intentionally provided, thereby further improving the reproducibility of the replicated painting.

[0028] Furthermore, the gloss adjustment layer may contain particles in addition to glitter. For example, when particles made of silica or synthetic resin are mixed into the ink for forming the gloss adjustment layer, minute irregularities due to the transparent particles can be imparted to the surface of the completed gloss adjustment layer, contributing to an appearance closer to that of the part made of rock pigment. The size of the particles can be appropriately determined in consideration of the mesh of the silk screen used.
