Description
本発明は、金箔等の金属箔による装飾が施された、障屏画等の古画を忠実に複製する方法に関する。 The present invention relates to a method for faithfully reproducing an old picture such as a hand-drawn picture decorated with a metal foil such as a gold foil.
襖絵、屏風絵および壁画等の文化遺産は人類にとって貴重な財産であり、後世に残すべきものである。しかし、それらは年々老朽化が進んでおり、現在、それらの保護が重要な課題となっている。 Cultural heritage such as samurai paintings, folding screen paintings and murals are precious assets for mankind and should be left to future generations. However, they are becoming obsolete year by year, and their protection is now an important issue.
それらの保護方法の一つとして、実物の複製を製作し、実物と複製物を置き換えるとともに実物を収蔵庫等に保管しておく方法がとられている。 As one of those protection methods, a method is used in which a replica of the actual product is produced, the actual product and the replicated product are replaced, and the actual product is stored in a storage or the like.
従来の複製方法として、高精度のデジタルカメラや大型スキャナ等の画像入力手段により、文化遺産の絵柄のデジタル画像データを取得し、そのデジタル画像データに基づいて紙に絵柄を印刷して複製物を製作する方法があるが、金属箔が施された絵柄については、金属箔色をインクのみで表現することはできなかった。そこで、金箔による装飾が施されたものについては、紙上に金箔を貼付し、その上にオフセット印刷を施すことによって、長い年月を経た金箔の色合い等を表現し、複製する方法がまた、存在する（特許文献１参照）。
しかしながら、この複製方法では、紙に貼付された一様な金属光沢の金属箔の上に、インクによって多様な色合いが表現されるに過ぎず、金属光沢が多様ではなかった。そのため、金箔色を表現した部分が実物と比較して立体感のない平坦な印象を与えてしまい、複製すべき古画の絵柄を忠実に再現することは困難であった。 However, in this duplicating method, various colors are merely expressed by ink on a uniform metal gloss metal foil affixed to paper, and the metal gloss is not diverse. Therefore, the portion expressing the gold foil color gives a flat impression without a three-dimensional effect compared to the real thing, and it has been difficult to faithfully reproduce the pattern of the old painting to be reproduced.
したがって本発明の目的は、金箔等の金属箔による装飾が施された古画を忠実に複製する方法を提供することによって、かかる従来技術の問題点を解決することにある。 Accordingly, an object of the present invention is to solve the problems of the prior art by providing a method of faithfully reproducing an old picture decorated with a metal foil such as a gold foil.

［実施形態１（金泥を用いる場合）］
第１の実施形態として、金箔による装飾が施された古画を、金泥を用いて複製する方法につき説明する。図４は、実施形態１にかかる複製方法を示すフロー図である。
まず、高精度のデジタルカメラまたはスキャナ等により、複製すべき古画のデジタル画像データを取得する（図４におけるＳ１）。次に、取得したデジタル画像データに基づいて、和紙６に複製すべき古画の絵柄をカラー印刷する（Ｓ２）。ここで、図１に示すとおり、印刷された絵柄７は金箔色を表現すべきでない領域１と、金箔色を表現すべき領域２とに区分される。
[Embodiment 1 (when using gold mud)]
As a first embodiment, a method for replicating an old picture decorated with gold leaf using gold mud will be described. FIG. 4 is a flowchart illustrating the duplication method according to the first embodiment.
First, digital image data of an old picture to be duplicated is acquired by a high-precision digital camera or scanner (S1 in FIG. 4). Next, based on the acquired digital image data, an old picture pattern to be reproduced on the Japanese paper 6 is color-printed (S2). Here, as shown in FIG. 1, the printed picture 7 is divided into a region 1 that should not represent the gold foil color and a region 2 that should represent the gold foil color.
次に、金箔色を表現すべき領域２の全体において、滲み防止のために礬砂液（膠液に明礬を加えたもの）を塗布する（Ｓ３）。そして、図２に示す金属光沢の高い金箔色に表現すべき領域３（図中の白色で示された領域）に、金属光沢の高い金パール（雲母にチタンをまき着色したもの）と第１の接着剤との混合物８を塗布する（Ｓ４）。ここで、表現すべき金属光沢の高低は、複製すべき古画の色調を参照することによって決定する。 Next, in the entire region 2 where the gold foil color is to be expressed, a cinnabar liquid (a solution obtained by adding alum to the glue liquid) is applied to prevent bleeding (S3). Then, in a region 3 (region shown in white in the figure) to be expressed in a gold foil color with a high metallic luster shown in FIG. 2, a gold pearl with a high metallic luster (a mica-plated titanium) and a first The mixture 8 with the adhesive is applied (S4). Here, the level of the metallic luster to be expressed is determined by referring to the color tone of the old painting to be reproduced.
塗布した金パール混合物８が完全に乾いた後、金箔色を表現すべき領域２の全体に、金パール混合物８よりも金属光沢の低い第１の金泥９（金粉を膠液で溶いたもの）を塗布する（Ｓ５）。 After the applied gold pearl mixture 8 is completely dried, the first gold mud 9 having a metallic luster lower than that of the gold pearl mixture 8 (the one in which gold powder is dissolved in a glue liquid) is formed in the entire region 2 where the gold foil color is to be expressed. Is applied (S5).
塗布した第１の金泥９が完全に乾いた後、図２に示す、金属光沢の高い金箔色に表現すべき領域３（図中の白色で示された領域）および金属光沢の更に低い金箔色に表現すべき領域５（図中の濃いグレーで示された領域）において、礬砂液を付着させた綿や布等を用いて第１の金泥９を擦り取り、下にある金パール混合物８および印刷された絵柄７を露出させる（Ｓ６）。ここで、擦り取られずに残っている第１の金泥９は、金属光沢の低い金箔色に表現すべき領域４（図中の薄いグレーで示された領域）を表現することになる。 After the applied first gold mud 9 is completely dried, the region 3 (region shown in white in the drawing) to be expressed in a gold foil color with a high metallic luster and a gold foil color with a lower metallic luster shown in FIG. In the region 5 to be expressed in (region shown in dark gray in the figure), the first gold mud 9 is scraped off using cotton, cloth or the like to which dredged sand liquid is adhered, and the gold pearl mixture 8 below Then, the printed picture 7 is exposed (S6). Here, the 1st gold mud 9 which remains without being scraped will express the area | region 4 (area | region shown with the light gray in the figure) which should be expressed by the gold foil color with a low metallic luster.
以上により、表現すべき金箔色が、それぞれ異なる金属光沢を有する金パール混合物８、第１の金泥９および印刷された絵柄７によって表現されるため、金属光沢が一様である場合と比較して立体感のある自然な金属箔色を再現でき、実物に忠実な複製物を製作することができる。 As described above, since the gold foil color to be expressed is expressed by the gold pearl mixture 8, the first gold mud 9, and the printed pattern 7 having different metallic luster, compared with the case where the metallic luster is uniform. A natural metal foil color with a three-dimensional effect can be reproduced, and a replica that is faithful to the real product can be produced.
更に金属光沢を多様に表現する必要があるときは、擦り取られずに残っている第１の金泥９の上に、第１の金泥９よりも濃度の薄い第２の金泥を重ね塗りしてもよい。それによって、既にある金属光沢とは別の金属光沢を有する領域を加えることができ、更に多様な金属光沢を表現することができる。 Furthermore, when it is necessary to express the metallic luster in various ways, the second gold mud having a concentration lower than that of the first gold mud 9 may be overcoated on the first gold mud 9 that remains without being scraped off. Good. Thereby, a region having a metallic luster different from the existing metallic luster can be added, and further various metallic luster can be expressed.
［実施形態２（金箔を用いる場合）］
次に、第二の実施形態として、金箔による装飾が施された古画を、金箔を用いて複製する方法につき説明する。図５は、実施形態２にかかる複製方法を示すフロー図である。
なお、金パール混合物８を塗布するステップ（図５におけるＳ４）までは前述の実施形態１と同様であるため、それ以降のステップ（Ｓ５〜）につき説明する。
[Embodiment 2 (when using gold leaf)]
Next, as a second embodiment, a method for replicating an old picture decorated with a gold foil using a gold foil will be described. FIG. 5 is a flowchart illustrating the duplication method according to the second embodiment.
In addition, since it is the same as that of the above-mentioned Embodiment 1 until the step (S4 in FIG. 5) of apply | coating the gold pearl mixture 8, it demonstrates per subsequent step (S5-).
塗布した金パール混合物８が完全に乾いた後、金箔色を表現すべき領域２の全体に、第２の接着剤を塗布によって適用し、その上に金パール混合物８よりも金属光沢の低い第１の金箔９’を貼付する（Ｓ５）。ここで、第２の接着剤は膠液であるのが好ましい。 After the applied gold pearl mixture 8 is completely dried, the second adhesive is applied to the whole area 2 where the gold foil color is to be expressed by coating, and the metal luster having a lower metallic luster than the gold pearl mixture 8 is applied thereon. 1 gold foil 9 'is affixed (S5). Here, the second adhesive is preferably a glue liquid.
また、第２の接着剤を適用する際、古画の絵柄をカラー印刷するのに用いた元のデジタル画像データに再び基づき、公知の画像処理プログラムを用いて古画の絵柄における金箔色領域を特定し、その領域上に、スクリーン印刷、オフセット印刷、フレキソ印刷またはグラビア印刷によって第２の接着剤を適用してもよい。この場合、公知の画像処理プログラムによれば、例えば、元のデジタル画像データにおける各ピクセルの色成分値を予め定められた閾値と比較することによって、または、元のデジタル画像データの取得時に検出した各ピクセルの光の反射率を予め定められた閾値と比較することによって、古画の絵柄における金箔色領域が特定される。
この構成によれば、第２の接着剤を自動的に、正確かつ効率良く適用することができる。なお、この場合の第２の接着剤は、アクリル系樹脂等の公知の印刷用接着剤であるのが好ましい。
In addition, when applying the second adhesive, based on the original digital image data used for color printing of the old picture pattern, the gold color area in the old picture pattern is determined using a known image processing program. A second adhesive may be applied on the area by screen printing, offset printing, flexographic printing or gravure printing. In this case, according to a known image processing program, for example, it is detected by comparing the color component value of each pixel in the original digital image data with a predetermined threshold or at the time of acquiring the original digital image data. By comparing the light reflectance of each pixel with a predetermined threshold value, the gold foil color region in the pattern of the old picture is specified.
According to this configuration, the second adhesive can be automatically and accurately applied efficiently. In this case, the second adhesive is preferably a known printing adhesive such as an acrylic resin.
塗布した第２の接着剤が完全に乾いた後、図２に示す金属光沢の高い金箔色に表現すべき領域３（図中の白色で示された領域）および金属光沢の更に低い金箔色に表現すべき領域５（図中の濃いグレーで示された領域）において、礬砂液を付着させた綿や布等を用いて第１の金箔９’を擦り取り、下にある金パール混合物８および印刷された絵柄７を露出させる（Ｓ６）。 After the applied second adhesive is completely dried, the region 3 (region shown in white in the figure) to be expressed in the gold foil color with a high metallic luster shown in FIG. In the region 5 to be expressed (the region shown in dark gray in the figure), the first gold foil 9 'is scraped off using cotton or cloth to which cinnabar liquid is adhered, and the gold pearl mixture 8 below is scraped off. Then, the printed picture 7 is exposed (S6).
この実施形態２においても実施形態１と同様に、実物に忠実な複製物を製作することができる。 Also in the second embodiment, as in the first embodiment, a replica faithful to the real object can be manufactured.
以上、具体例を例示しつつ、本発明の実施の形態について説明したが、本発明はこれらの具体例に限定されるものではない。例えば前述の両実施形態において、複製すべき古画の絵柄を和紙６に印刷したが、印刷可能な紙であればよく、実物を忠実に表現できる紙を適宜選択すればよい。また、印刷はインクジェット方式、オフセット方式およびスクリーン方式等の一般的なカラー印刷であってよい。なお、印刷に用いるインクは耐水性を有するのが好ましい。 As mentioned above, although embodiment of this invention was described, demonstrating a specific example, this invention is not limited to these specific examples. For example, in both the above-described embodiments, the pattern of the old picture to be duplicated is printed on the Japanese paper 6. However, any printable paper may be used, and paper that can faithfully represent the real thing may be selected as appropriate. The printing may be general color printing such as an inkjet method, an offset method, and a screen method. The ink used for printing preferably has water resistance.
また、滲み防止のために礬砂液を塗布したが、他の一般的な滲み防止剤であってもよい。更に、使用する紙および印刷インクに応じて適宜省略してもよい。 Moreover, although the cinnabar liquid was applied for preventing bleeding, other general bleeding preventing agents may be used. Furthermore, it may be omitted as appropriate according to the paper and printing ink used.
また、表現すべき金属光沢の高低を決定する際、直接観察できない場合や判断が難しい場合は、取得した複製すべき古画のデジタル画像データに対して、例えばコントラストを大きくする等、金属光沢の高低を視覚的に判断し易くするように画像処理を施し、それに基づいて決定してもよい。 Also, when determining the level of metallic luster to be expressed, if direct observation is not possible or judgment is difficult, the metallic luster of the acquired old image digital image data to be duplicated, such as by increasing the contrast, is used. Image processing may be performed so as to make it easy to visually determine the height, and the determination may be made based on the image processing.
また、金属光沢の高い金箔色を有する領域を表現するのに金パール混合物８を用いたが、高い金属光沢を有するものであればよく、第２の金箔８’を用いてもよい。更に、金属光沢の高い金箔色を有する粉８（または第２の金箔８’）にかかる第１の接着剤は、その上に塗布または貼付された後に擦り取られる第１の金泥９（または第１の金箔９’）と一緒に取り去られないよう、第１の金泥９（または第１の金箔９’）にかかる膠液等の接着剤（または第２の接着剤）よりも、強い接着力を有するのが好ましい。 Further, the gold pearl mixture 8 is used to express a region having a gold foil color with a high metallic luster, but the second gold foil 8 'may be used as long as it has a high metallic luster. Further, the first adhesive applied to the powder 8 (or the second gold foil 8 ′) having a gold foil color with a high metallic luster is applied to the first gold mud 9 (or the second gold mud 9) which is scraped off after being applied or pasted thereon. Adhesion stronger than the adhesive (or the second adhesive) such as glue applied to the first gold mud 9 (or the first gold foil 9 ') so as not to be removed together with the first gold foil 9') It is preferable to have power.
また、金属光沢の異なる金箔色領域を形成する際、複製すべき古画の色調に応じて、金属光沢とともにその色合いに変化をもたせるようにしてもよい。例えば、金属光沢の高い金箔色に表現すべき領域に対して、金属光沢の高い、黄色の色合いを有する金箔色の粉を塗布するとともに、金属光沢の低い金箔色に表現すべき領域に対し、金属光沢の低い、赤色の色合いを有する金泥を塗布する等である。それによって、金箔による装飾が施された複製すべき古画をより忠実に複製することができる。 Further, when forming a gold foil color region having a different metallic luster, the hue may be changed along with the metallic luster according to the color tone of the old painting to be reproduced. For example, for a region that should be expressed in a gold foil color with a high metallic luster, a gold foil color powder having a high metallic luster and a yellow tint is applied, and for a region that should be expressed in a gold foil color with a low metallic gloss, For example, gold mud having a low metallic luster or a red color is applied. Thereby, it is possible to more faithfully reproduce the old painting to be duplicated decorated with gold leaf.
また、前述の両実施形態では金箔の場合を例示したが、複製すべき古画に応じて銀箔やアルミ箔等の金属箔を使用することもできる。 Moreover, although the case of gold foil was illustrated in both above-mentioned embodiment, metal foils, such as silver foil and aluminum foil, can also be used according to the old picture which should be reproduced.
また、全作業完了後、複製物を保護するために、水性ウレタン等のコーティング剤を全体に塗布してもよい。 In addition, a coating agent such as aqueous urethane may be applied to the whole after the completion of all operations in order to protect the duplicate.
