Description

シガレットパッケージ、及びシガレットパッケージの印刷方法Cigarette package and method for printing cigarette package
　本発明は、シガレットパッケージ、及びシガレットパッケージの印刷方法の技術に関する。 The present invention relates to a cigarette package and a technique for printing a cigarette package.
　たばこ商品等の被収容物を収容する包装（パッケージ）として、ソフトパック型パッケージ、ハードボックス型パッケージ等が知られている。また、これらのシガレットパッケージには、パッケージの表面に種々の印刷技術を用いて銘柄や社名等が印刷されている。 2. Description of the Related Art Soft pack type packages, hard box type packages, and the like are known as packages that contain articles such as tobacco products. Also, in these cigarette packages, brand names, company names, and the like are printed on the surface of the package using various printing techniques.
　一方、シガレットパッケージの印刷に限らず、既存の印刷技術の一つとして、高輝度金属インキを使用した印刷技術が知られている（例えば、特許文献１、２を参照）。例えば、特許文献１には、基材層と、基材層の上に色インキを使用した印刷により形成された色印刷層と、色印刷層の上に高輝度インキを使用した印刷により形成された高輝度印刷層と、高輝度印刷層の上に表面を保護しさらに光沢を付与する保護層とからなる印刷物が開示されている。 On the other hand, printing technology using high-luminance metal ink is known as one of existing printing technologies, not limited to cigarette package printing (see, for example, Patent Documents 1 and 2). For example, Patent Document 1 includes a base material layer, a color printing layer formed by printing using a color ink on the base material layer, and printing using a high brightness ink on the color printing layer. Further, there has been disclosed a printed matter comprising a high-brightness printing layer and a protective layer that protects the surface and imparts gloss on the high-brightness printing layer.

　高輝度印刷層を備える従来の印刷物では、高輝度印刷層の上に保護層を設けることが一般的であった。また、高輝度金属インキを使用した印刷技術は、シガレットパッケージの印刷にも用いられている。ここで、図１は、従来のシガレットパッケージの一例の斜視図を示す。また、図２は、図１のａ－ａ断面に対応する、従来の印刷技術によって印刷が施されたシガレットパッケージの本体を構成する紙体の断面図を示す。図２に示すように、シガレットパッケージに高輝度金属インキを使用する場合、従来技術では高輝度金属インキの上にＯＰニスなどの保護層が設けられていた。しかしながら、高輝度金属インキの上に保護層を設けると、輝度感が低下することが懸念されていた。なお、輝度は、物体表面の輝きを示し、光沢は、物体表面のつや（艶）を示す。 In a conventional printed matter provided with a high brightness print layer, it is common to provide a protective layer on the high brightness print layer. Moreover, the printing technique using high-intensity metal ink is also used for the printing of a cigarette package. Here, FIG. 1 shows a perspective view of an example of a conventional cigarette package. FIG. 2 is a cross-sectional view of the paper body constituting the main body of the cigarette package printed by the conventional printing technique, corresponding to the aa cross section of FIG. As shown in FIG. 2, when using a high-intensity metal ink for a cigarette package, in the prior art, a protective layer such as OP varnish was provided on the high-intensity metal ink. However, when a protective layer is provided on the high-brightness metal ink, there is a concern that the brightness feeling is lowered. The luminance indicates the brightness of the object surface, and the gloss indicates the gloss (gloss) of the object surface.
　本発明は、上記の問題に鑑み、高輝度金属インキが使用されたシガレットパッケージの輝度感を従来よりも向上する技術を提供することを課題とする。 In view of the above problems, an object of the present invention is to provide a technique for improving the brightness feeling of a cigarette package using a high-intensity metal ink as compared with the conventional technique.
　本発明は、上述した課題を解決するため、高輝度金属インキを使用する領域と高輝度金属インキ以外のインキを使用する領域とで、インキの階層構造を変えることとした。 In the present invention, in order to solve the above-described problems, the hierarchical structure of the ink is changed between the area where the high-intensity metal ink is used and the area where the ink other than the high-intensity metal ink is used.
　より詳細には、本発明に係るシガレットパッケージは、シガレットパッケージの本体を構成する原紙と、前記原紙の上に形成される、色インキからなる少なくとも１層の色インキ層と、前記色インキ層の上に形成され、該色インキ層を保護する保護層と、前記保護層の少なくとも一部を覆う、高輝度金属インキからなる高輝度金属インキ層と、を備える。 More specifically, the cigarette package according to the present invention includes a base paper constituting the main body of the cigarette package, at least one color ink layer made of color ink formed on the base paper, and the color ink layer. A protective layer that is formed thereon and protects the color ink layer; and a high-brightness metal ink layer made of high-brightness metal ink that covers at least a part of the protective layer.
　本発明に係るシガレットパッケージは、少なくとも一部に保護層を覆う高輝度金属インキ層を有することを特徴とする。換言すると、本発明では、高輝度金属インキ層が印刷される領域では、保護層が高輝度金属インキ層の上層ではなく、高輝度金属インキ層の下層、すなわち下地として配置される。これにより、高輝度金属インキ層の上に保護層を設けることで発生する輝度感の低下を回避することができる。その結果、輝度感を従来よりも向上することができる。また、高輝度金属インキ層の下方は、原紙の表面から順に、色インキ層、保護層が印刷され、各層が形成される毎に表面の凹凸が減少する。つまり、原紙の表面の粗さが色インキ層が印刷されることで平滑化され、更に色インキ層の上に保護層が形成されることでより平滑化される。このように高輝度金属インキ層は、下地処理が段階的に行われた上で印刷されることから、輝度感を従来よりも向上することができる。なお、本発明の高輝度金属インキ層は、十分な耐久性を有している。従って、例えば、既存のたばこ包装機において、本発明の印刷が施されたシガレットパッケージブランクを使用することもできる。 The cigarette package according to the present invention is characterized by having a high-intensity metal ink layer covering at least a part of the protective layer. In other words, in the present invention, in the region where the high-brightness metal ink layer is printed, the protective layer is arranged not as an upper layer of the high-brightness metal ink layer but as a lower layer of the high-brightness metal ink layer, that is, a base. Thereby, the fall of the brightness | luminance feeling which generate | occur | produces by providing a protective layer on a high-intensity metal ink layer can be avoided. As a result, the luminance feeling can be improved as compared with the conventional case. In addition, a color ink layer and a protective layer are printed in order from the surface of the base paper below the high-brightness metal ink layer, and surface irregularities are reduced each time each layer is formed. That is, the roughness of the surface of the base paper is smoothed by printing the color ink layer, and further smoothed by forming a protective layer on the color ink layer. As described above, since the high-brightness metal ink layer is printed after the base treatment is performed stepwise, the brightness feeling can be improved as compared with the conventional case. In addition, the high-intensity metal ink layer of this invention has sufficient durability. Therefore, for example, in an existing cigarette wrapping machine, a cigarette package blank on which printing of the present invention has been performed can also be used.
　シガレットパッケージには、ソフトパック型パッケージ、ハードボックス型パッケージ等が含まれる。なお、シガレットパッケージは、たばこ商品を収容可能なパッケージであればその形態は特に限定されない。 Cigarette packages include soft pack type packages and hard box type packages. The form of the cigarette package is not particularly limited as long as it is a package that can accommodate tobacco products.
　ここで、本発明に係るシガレットパッケージは、最表層に前記高輝度金属インキ層を有する高輝度金属インキ領域と、最表層に前記保護層を有する色インキ領域と、を更に備えていてもよい。高輝度金属インキ領域では、高輝度金属インキ層が最表層に位置することから、高輝度金属インキ層の上に保護層が印刷されていた従来のパッケージに比べて、輝度感を向上することができる。一方、高輝度金属インキ領域以外の領域である色インキ領域では色インキ層を保護層により保護することができる。 Here, the cigarette package according to the present invention may further include a high luminance metal ink region having the high luminance metal ink layer on the outermost layer and a color ink region having the protective layer on the outermost layer. In the high-brightness metal ink region, the high-brightness metal ink layer is located on the outermost layer, so the brightness feeling can be improved compared to the conventional package in which the protective layer is printed on the high-brightness metal ink layer. it can. On the other hand, the color ink layer can be protected by the protective layer in the color ink region which is a region other than the high-luminance metal ink region.
　また、本発明に係るシガレットパッケージにおいて、前記高輝度金属インキ層は、リーフィングタイプのインキからなる層とすることができる。リーフィングタイプのインキを用いることで、リーフ状の金属片が高輝度金属インキ層の上部に散らばって折り重なるように形成され、色インキ層が透けるといった色インキ層の影響を受け難くなる。その結果、輝度感を向上することができる。 Also, in the cigarette package according to the present invention, the high brightness metal ink layer may be a layer made of leafing type ink. By using the leafing type ink, the leaf-shaped metal pieces are scattered and formed on the upper part of the high-brightness metal ink layer so that the color ink layer is less affected by the color ink layer. As a result, the brightness feeling can be improved.
　また、本発明に係るシガレットパッケージにおいて、前記高輝度金属インキ層の表面は、該表面を平滑化するための押し加工が施されていてもよい。押し加工が施されることで、高輝度金属インキ層の表面がより平滑化され、輝度感がより向上する。 Further, in the cigarette package according to the present invention, the surface of the high brightness metal ink layer may be subjected to a pressing process for smoothing the surface. By performing the pressing process, the surface of the high-brightness metal ink layer is further smoothed, and the brightness feeling is further improved.
　また、本発明に係るシガレットパッケージは、最表層に前記高輝度金属インキ層を有する高輝度金属インキ領域と、最表層に前記保護層を有する色インキ領域と、前記高輝度金属インキ領域において、前記保護層の上に形成され、保護層と高輝度金属インキとの接着力を高めるアンカー層と、を更に備えるようにしてもよい。アンカー層を備えることで、保護層と高輝度金属インキとの接着力を高めることができる。また、アンカー層が保護層の上に設けられており、シガレットパッケージの表面がより平滑になる。 Further, the cigarette package according to the present invention is a high-brightness metal ink region having the high-brightness metal ink layer on the outermost layer, a color ink region having the protective layer on the outermost layer, and the high-brightness metal ink region, You may make it further provide the anchor layer which is formed on a protective layer and raises the adhesive force of a protective layer and high-intensity metal ink. By providing the anchor layer, the adhesive force between the protective layer and the high-intensity metal ink can be increased. Moreover, the anchor layer is provided on the protective layer, and the surface of the cigarette package becomes smoother.
　ここで、本発明は、シガレットパッケージの印刷方法として特定することができる。すなわち、本発明は、シガレットパッケージの印刷方法であって、前記シガレットパッケージの本体を構成する原紙の上に少なくとも１層の色インキ層を印刷する色インキ層印刷工程と、前記色インキ層の上に、該色インキ層を保護する保護層を形成する保護層印刷工程と、前記保護層の少なくとも一部を覆う、高輝度金属インキ層を印刷する高輝度金属インキ層印刷工程と、を備える。 Here, the present invention can be specified as a method for printing a cigarette package. That is, the present invention is a method for printing a cigarette package, comprising: a color ink layer printing step of printing at least one color ink layer on a base paper constituting the main body of the cigarette package; And a protective layer printing step for forming a protective layer for protecting the color ink layer, and a high luminance metallic ink layer printing step for printing a high luminance metallic ink layer covering at least a part of the protective layer.
　本発明によれば、保護層の少なくとも一部を覆う高輝度金属インキ層を印刷することで、高輝度金属インキ層が印刷される領域では、保護層が高輝度金属インキ層の上層ではなく、高輝度金属インキ層の下層、すなわち下地として配置される。これにより、高輝度金属インキ層の上に保護層を設けることで発生する輝度感の低下を回避することができ、輝度感を従来よりも向上することができる。また、高輝度金属インキ層が、下地処理が段階的に行われた上で印刷されることから、輝度感を従来よりも向上することができる。 According to the present invention, by printing a high-brightness metal ink layer covering at least a part of the protective layer, in the region where the high-brightness metal ink layer is printed, the protective layer is not an upper layer of the high-brightness metal ink layer, It is arranged as a lower layer of the high brightness metal ink layer, that is, as a base. As a result, it is possible to avoid a decrease in luminance caused by providing a protective layer on the high-luminance metal ink layer, and it is possible to improve the luminance feeling compared to the prior art. In addition, since the high-brightness metal ink layer is printed after the base treatment is performed in stages, the brightness feeling can be improved as compared with the prior art.
　また、本発明に係るシガレットパッケージの印刷方法において、最表層の印刷工程として前記高輝度金属インキ層印刷工程を行い、最表層に前記高輝度金属インキ層を有する高輝度金属インキ領域を形成し、最表層の印刷工程として前記保護層印刷工程を行い、最表層に前記保護層を有する色インキ領域を形成するようにしてもよい。高輝度金属インキ領域では、高輝度金属インキ層が最表層に位置することから、高輝度金属インキ層の上に保護層が印刷されていた従来のパッケージに比べて、輝度感を向上することができる。一方、高輝度金属インキ領域以外の領域である色インキ領域では色インキ層を保護層により保護することができる。 Further, in the cigarette package printing method according to the present invention, the high luminance metal ink layer printing step is performed as the outermost layer printing step, and the high luminance metal ink region having the high luminance metal ink layer is formed on the outermost layer, The protective layer printing step may be performed as the outermost layer printing step to form a color ink region having the protective layer on the outermost layer. In the high-brightness metal ink region, the high-brightness metal ink layer is located on the outermost layer, so the brightness feeling can be improved compared to the conventional package in which the protective layer is printed on the high-brightness metal ink layer. it can. On the other hand, the color ink layer can be protected by the protective layer in the color ink region which is a region other than the high-luminance metal ink region.
　また、本発明に係るシガレットパッケージの印刷方法において、前記高輝度金属インキ層印刷工程では、リーフィングタイプのインキを用いて前記高輝度金属インキ層を印刷してもよい。リーフィングタイプのインキを用いることで、リーフ状の金属片が高輝度金属インキ層の上部にリーフィング状に形成され、色インキ層が透けるなどの色インキ層の色の影響を受け難くなる。その結果、輝度感を向上することができる。 In the cigarette package printing method according to the present invention, in the high brightness metal ink layer printing step, the high brightness metal ink layer may be printed using leafing type ink. By using the leafing type ink, a leaf-like metal piece is formed in a leafing shape on the upper part of the high-brightness metal ink layer, so that it is difficult to be influenced by the color of the color ink layer such that the color ink layer is transparent. As a result, the brightness feeling can be improved.
　また、本発明に係るシガレットパッケージの印刷方法は、前記高輝度金属インキ層の表面に、該表面を平滑化するための押し加工を施す押し加工工程を更に備えるようにしてもよい。押し加工を施すことで、高輝度金属インキ層の表面がより平滑化され、輝度感がより向上する。 Further, the cigarette package printing method according to the present invention may further include a pressing process for applying a pressing process to smooth the surface of the high brightness metal ink layer. By applying the pressing process, the surface of the high-brightness metal ink layer is further smoothed, and the brightness feeling is further improved.
　また、本発明に係るシガレットパッケージの印刷方法は、最表層の印刷工程として前記高輝度金属インキ層印刷工程を行い、最表層に前記高輝度金属インキ層を有する高輝度金属インキ領域を形成し、最表層の印刷工程として前記保護層印刷工程を行い、最表層に前記保護層を有する色インキ領域を形成し、前記高輝度金属インキ領域において、前記保護層の上に形成され、保護層と高輝度金属インキとの接着力を高めるアンカー層を形成するアンカー層形成工程を更に備えるようにしてもよい。アンカー層を形成することで、保護層と高輝度金属インキとの接着力を高めることができる。 Moreover, the cigarette package printing method according to the present invention performs the high-brightness metal ink layer printing step as the outermost layer printing step, and forms a high-brightness metal ink region having the high-brightness metal ink layer on the outermost layer, The protective layer printing step is performed as the outermost layer printing step, a color ink region having the protective layer is formed on the outermost layer, and the high-intensity metal ink region is formed on the protective layer. You may make it further provide the anchor layer formation process which forms the anchor layer which raises the adhesive force with a brightness | luminance metal ink. By forming the anchor layer, the adhesive force between the protective layer and the high brightness metal ink can be increased.
　本発明によれば、高輝度金属インキが使用されたシガレットパッケージの輝度感を従来よりも向上することができる。 According to the present invention, the brightness feeling of the cigarette package using the high-brightness metal ink can be improved as compared with the conventional case.

　次に、本発明に係る実施形態について図面に基づいて説明する。なお、以下で説明する実施形態は本発明を実施するための例示であり、本発明は以下で説明する態様に限定されない。 Next, an embodiment according to the present invention will be described with reference to the drawings. In addition, embodiment described below is an illustration for implementing this invention, and this invention is not limited to the aspect demonstrated below.
　＜構成＞
　実施形態に係るシガレットパッケージ１（以下、単にパッケージとする。）は、図３に示すように、ハードボックス型パッケージである。パッケージ１は、本体２と蓋部３とからなる直方体形状であり、本体２の背面上部にあるヒンジ４を軸として蓋部３が開閉自在である。パッケージ１の内部には、たばこ商品として、紙巻たばこ（フィルタシガレット、両切たばこ（フィルタ無し））、シガー（葉巻）、シガリロ、無煙たばこ（かぎたばこ、かみたばこ）、電子たばこ等を収容可能である。また、パッケージ１には、銘柄、社名、内容表示等が印刷され、印刷表示の一部に高輝度金属インキが用いられている。なお、本実施形態では、ハードボックス型パッケージを例に説明するが、パッケージは、ソフトパック型パッケージなど、たばこ商品を収容可能なパッケージであればその形態は特に限定されない。 <Configuration>
A cigarette package 1 according to the embodiment (hereinafter simply referred to as a package) is a hard box type package as shown in FIG. The package 1 has a rectangular parallelepiped shape including a main body 2 and a lid portion 3, and the lid portion 3 can be opened and closed with a hinge 4 at the upper back of the main body 2 as an axis. Inside the package 1, cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), cigarillos, smokeless cigarettes (cig cigarettes, cigarettes), electronic cigarettes, etc. can be accommodated in the package 1 is there. The package 1 is printed with brand name, company name, content display, and the like, and high-intensity metal ink is used as part of the printed display. In the present embodiment, a hard box type package will be described as an example. However, the form is not particularly limited as long as the package can accommodate tobacco products such as a soft pack type package.
　ここで、図４は、図３のａ－ａ断面に対応する、印刷が施されたパッケージを構成する紙体の断面図を示す。図４に示すように、実施形態に係るパッケージ１の紙体は、印刷が施されることで、原紙２１、第一インキ層２２、第二インキ層２３、ＯＰニス層２４、専用アンカー層２５、高輝度金属インキ層２６によって構成されている。 Here, FIG. 4 shows a cross-sectional view of the paper body constituting the printed package corresponding to the aa cross section of FIG. As shown in FIG. 4, the paper body of the package 1 according to the embodiment is subjected to printing, whereby the base paper 21, the first ink layer 22, the second ink layer 23, the OP varnish layer 24, and the dedicated anchor layer 25. The high-brightness metal ink layer 26 is used.
　原紙２１は、パッケージ１の本体２及び蓋部３を構成する紙体の基材である。原紙２１には、片面コート紙、アートポスト紙、キャストコート紙等を用いることができる。原紙２１に表面が平滑な紙を用いることで、輝度感をより高めることができる。 The base paper 21 is a paper base material that constitutes the main body 2 and the lid 3 of the package 1. As the base paper 21, one-side coated paper, art post paper, cast coated paper, or the like can be used. By using a paper with a smooth surface as the base paper 21, it is possible to enhance the brightness.
　第一インキ層２２及び第二インキ層２３は、原紙２１の表面に色インキの印刷を施すことで形成される層である。第一インキ層２２及び第二インキ層２３は、本発明に係る色インキ層に相当する。第一インキ層２２及び第二インキ層２３は、パッケージ１のデザインを表現する層であり、高輝度金属インキが用いられる領域以外の、銘柄、社名、内容表示等を表現する。なお、図４では、色インキ層として、２種類のインキ層が形成されているが、色インキ層の数は、パッケージのデザインに応じて適宜変更可能である。高輝度金属インキが用いられる領域は、本発明の高輝度金属インキ領域に相当し、それ以外の領域は、本発明の色インキ領域に相当する。 The first ink layer 22 and the second ink layer 23 are layers formed by printing color ink on the surface of the base paper 21. The first ink layer 22 and the second ink layer 23 correspond to the color ink layer according to the present invention. The first ink layer 22 and the second ink layer 23 are layers that represent the design of the package 1 and represent brands, company names, content displays, and the like other than the region where the high-intensity metal ink is used. In FIG. 4, two types of ink layers are formed as the color ink layers, but the number of color ink layers can be changed as appropriate according to the design of the package. The region where the high brightness metal ink is used corresponds to the high brightness metal ink region of the present invention, and the other region corresponds to the color ink region of the present invention.
　ＯＰニス層２４は、色インキ層（本実施形態では、第二インキ層）の表面にＯＰ（Over Print）ニス加工を施すことで形成される層である。ＯＰニス層２４は、本発明に係る保護層に相当する。ＯＰニス層２４は、色インキ層を傷や汚れから保護し、また、色インキ層の表面に光沢を付与する。ＯＰニス層２４は、高輝度金属インキが用いられる領域以外の領域では最表層となる。 The OP varnish layer 24 is a layer formed by performing OP (Over Print) varnish processing on the surface of the color ink layer (in the present embodiment, the second ink layer). The OP varnish layer 24 corresponds to the protective layer according to the present invention. The OP varnish layer 24 protects the color ink layer from scratches and dirt, and also gives gloss to the surface of the color ink layer. The OP varnish layer 24 is the outermost layer in a region other than the region where the high brightness metal ink is used.
　ＯＰニスは、ＵＶ、油性、水性の３種類に区別される。高輝度金属インキは油性であることから、ＯＰニスも油性であることが望ましい。また、前記３種類のＯＰニスは、夫々がグロスタイプとマットタイプとに更に区別される。本実施形態では、表面をより平滑化するため、グロスタイプを用いることが望ましい。更に、たばこのパッケージのＯＰニスに求められる特性として、滑り性、耐摩擦性、耐熱性、耐光性などが例示される。本実施形態では、高輝度金属インキが用いられる領域におけるＯＰニスは、特に滑り性が低い（高擦係数、表面が平滑）ことが望ましい。一方で、高輝度金属インキが用いられる領域以外の領域におけるＯＰニスは、滑り性が高いことが望ましい。そこで、ＯＰニス層２４は、特性の異なるＯＰニスを複数用いて形成してもよい。例えば、特性の異なるＯＰニスを領域ごとに分けてニス加工し、ＯＰニス層２４を形成してもよい。また、滑り性が高いＯＰニスを用いてニス加工し、高輝度金属インキが用いられる領域にのみ更に滑り性が低いＯＰニスを用いてニス加工し、ＯＰニス層２４を形成するようにしてもよい。 · OP varnish is classified into three types: UV, oily and aqueous. Since high brightness metal ink is oily, it is desirable that OP varnish is also oily. The three kinds of OP varnishes are further classified into a gloss type and a mat type, respectively. In the present embodiment, it is desirable to use a gloss type in order to further smooth the surface. Furthermore, examples of the characteristics required for the OP varnish of the cigarette package include slipperiness, friction resistance, heat resistance, and light resistance. In this embodiment, it is desirable that the OP varnish in the region where the high-brightness metallic ink is used has particularly low slipperiness (high friction coefficient, smooth surface). On the other hand, it is desirable that the OP varnish in the region other than the region where the high-brightness metal ink is used has high slipperiness. Therefore, the OP varnish layer 24 may be formed using a plurality of OP varnishes having different characteristics. For example, the OP varnish 24 may be formed by varnishing OP varnishes having different characteristics for each region. Alternatively, the OP varnish may be formed using OP varnish having high slipperiness, and varnishing using OP varnish having lower slipperiness only in the region where the high-brightness metal ink is used. Good.
　専用アンカー層２５は、高輝度金属インキの接着性を高めるためにアンカーコート剤（以下、単にアンカーともいう）を塗布することで形成される層である。専用アンカー層２５を形成することで、高輝度金属インキの接着性をより高めることができる。なお、専用アンカー層２５を省略し、ＯＰニス層２４の上に直接高輝度金属インキ層２６を形成してもよい。 The dedicated anchor layer 25 is a layer formed by applying an anchor coating agent (hereinafter also simply referred to as an anchor) in order to enhance the adhesiveness of the high-brightness metal ink. By forming the dedicated anchor layer 25, the adhesiveness of the high brightness metal ink can be further increased. The dedicated anchor layer 25 may be omitted, and the high brightness metal ink layer 26 may be formed directly on the OP varnish layer 24.
　アンカーは、ＵＶ、油性、水性の３種類に区別される。高輝度金属インキは油性であることから、アンカーも油性であることが望ましい。更に、たばこのパッケージのアンカーに求められる特性として、アンカーと接する層との密着性、平滑性が例示される。本実施形態では、アンカーは、高い密着性と平滑性を有していることが望ましい。 ¡Anchors are classified into three types: UV, oily, and aqueous. Since the high-intensity metal ink is oily, it is desirable that the anchor is oily. Furthermore, the properties required for the anchor of the cigarette package include adhesion and smoothness with the layer in contact with the anchor. In this embodiment, it is desirable that the anchor has high adhesion and smoothness.
　高輝度金属インキ層２６は、専用アンカー層２５又はＯＰニス層２４の上に、高輝度金属インキの印刷を施すことで形成される層である。換言すると、高輝度金属インキ層２６は、専用アンカー層２５又はＯＰニス層２４の一部を覆うように形成される。本実施形態では、高輝度金属インキとして蒸着アルミリーフィングタイプインキが用いられる。これにより、リーフ状のアルミニウム片が高輝度金属インキ層の上部に、葉が散らばって折り重なるようにリーフィング状に形成される。従って、リーフ状のアルミニウム片が表面に近い位置に存在し、また、色インキ層の色が透けるなどの色インキ層の色の影響を受け難くなる。その結果、輝度感を向上することができる。 The high brightness metal ink layer 26 is a layer formed by printing high brightness metal ink on the dedicated anchor layer 25 or the OP varnish layer 24. In other words, the high-brightness metal ink layer 26 is formed so as to cover a part of the dedicated anchor layer 25 or the OP varnish layer 24. In this embodiment, vapor deposition aluminum leaf type ink is used as the high brightness metal ink. Thereby, the leaf-like aluminum piece is formed in a leafing shape on the upper part of the high-brightness metal ink layer so that the leaves are scattered and folded. Accordingly, the leaf-shaped aluminum piece is present at a position close to the surface, and it is difficult to be influenced by the color of the color ink layer such that the color of the color ink layer is transparent. As a result, the brightness feeling can be improved.
　高輝度金属インキは、油性であることが望ましい。高輝度金属インキには、ＤＩＣ株式会社製のスーパーシルバー（商品名）、株式会社Ｔ＆Ｋ　ＴＯＫＡ製のＮＫ蒸着シルバー（商品名）、東洋インキ株式会社製のシルバーキングレオ（商品名）が例示される。 It is desirable that the high brightness metal ink is oily. Examples of the high-intensity metal ink include Super Silver (trade name) manufactured by DIC Corporation, NK-deposited silver (trade name) manufactured by T & K Corporation, and Silver King Leo (trade name) manufactured by Toyo Ink Co., Ltd.
　なお、本実施形態では、高輝度金属インキ層２６の表面にエンボス加工が施され、高輝度金属インキ層２６の表面が平滑化されている。これにより、高輝度金属インキ層２６の表面における乱反射が抑制され、輝度感が更に向上する。エンボス加工は、本発明に係る押し加工に相当する。エンボス加工に代えて、デボス加工、型押し加工を施してもよい。 In the present embodiment, the surface of the high-brightness metal ink layer 26 is embossed, and the surface of the high-brightness metal ink layer 26 is smoothed. Thereby, irregular reflection on the surface of the high-brightness metal ink layer 26 is suppressed, and the brightness feeling is further improved. The embossing corresponds to the pressing according to the present invention. Instead of embossing, debossing or embossing may be performed.
　ここで、図５は、実施形態に係る印刷が施されたパッケージを構成する紙体の断面詳細図を示す。なお、図５は、説明の便宜上、原紙２１や各層の表面の凹凸を強調して示している。図５に示すように、原紙２１の表面には、凹凸が存在するが、第一インキ層２２、第二インキ層２３、ＯＰニス層２４が形成されることで、表面が段階的に平滑化されている。つまり、高輝度金属インキ層２６は、表面が最も平滑化されたＯＰニス層２４の上に、更に専用アンカー層２５を介して印刷されている。専用アンカー層２５を介することでＯＰニス層２４と高輝度金属インキ層２６との接着性が向上する。また、表面が最も平滑化されたＯＰニス層２４の上に専用アンカー層２５を介して高輝度金属インキ層２６が形成されることで、輝度感が向上する。 Here, FIG. 5 shows a detailed cross-sectional view of a paper body constituting a package on which printing according to the embodiment is performed. In FIG. 5, for convenience of explanation, the surface of the base paper 21 and each layer is highlighted. As shown in FIG. 5, the surface of the base paper 21 has irregularities, but the surface is smoothed in steps by forming the first ink layer 22, the second ink layer 23, and the OP varnish layer 24. Has been. That is, the high-brightness metallic ink layer 26 is printed on the OP varnish layer 24 whose surface is most smoothed via the dedicated anchor layer 25. The adhesion between the OP varnish layer 24 and the high brightness metal ink layer 26 is improved by using the dedicated anchor layer 25. Moreover, the high brightness metallic ink layer 26 is formed on the OP varnish layer 24 whose surface is most smoothed via the dedicated anchor layer 25, thereby improving the brightness.
　また、図６Ａは、エンボス加工を施した、高輝度金属インキ層の断面詳細図を示し、図６Ｂは、エンボス加工を施していない、高輝度金属インキ層の断面詳細図を示す。なお、図６Ａ、図６Ｂにおいても、説明の便宜上、リーフ状のアルミニウム片や、高輝度金属インキ層２６の表面の凹凸を強調して示している。図６Ａ、図６Ｂに示すように、リーフ状のアルミニウム片が高輝度金属インキ層２６の上部にリーフィング状（葉が散らばって折り重なるように）に形成される。その結果、高輝度金属インキ層２６の下層にある色インキ層（図示せず）の色が透けるなどの色インキ層の影響を受け難くなり、輝度感が向上する。また、高輝度金属インキ層２６の表面にエンボス加工を施すことで、高輝度金属インキ層２６の表面が平滑化される。その結果、高輝度金属インキ層２６の表面に入射した光は、乱反射せず、正反射するようになり、輝度感がより向上する。 6A shows a detailed cross-sectional view of the high-intensity metal ink layer that has been embossed, and FIG. 6B shows a detailed cross-sectional view of the high-intensity metal ink layer that has not been embossed. In FIGS. 6A and 6B, for convenience of explanation, the unevenness on the surface of the leaf-shaped aluminum piece and the high-brightness metal ink layer 26 is also highlighted. As shown in FIGS. 6A and 6B, a leaf-shaped aluminum piece is formed in a leafing shape (so that the leaves are scattered and folded) on the high-brightness metal ink layer 26. As a result, the color ink layer (not shown) in the lower layer of the high-brightness metal ink layer 26 is hardly affected by the color ink layer such as the color being transparent, and the brightness feeling is improved. Moreover, the surface of the high-intensity metal ink layer 26 is smoothed by embossing the surface of the high-intensity metal ink layer 26. As a result, the light incident on the surface of the high-brightness metallic ink layer 26 is not diffusely reflected but is regularly reflected, and the brightness feeling is further improved.
　＜印刷方法＞
　図７は、実施形態に係る印刷方法の工程を示す。本実施形態に係る印刷方法は、インキの転移量に優れたグラビア印刷により行うことが最も好ましい。但し、本実施形態に係る印刷方法は、オフセット印刷、オフセットＵＶ印刷などの公知の印刷技術によっても実現可能である。グラビア印刷による場合には、公知のグラビア印刷機を用いて印刷することができる。また、他の公知の印刷技術による場合には、公知の印刷技術に対応した印刷機を用いて印刷することができる。 <Printing method>
FIG. 7 shows steps of the printing method according to the embodiment. The printing method according to the present embodiment is most preferably performed by gravure printing having an excellent ink transfer amount. However, the printing method according to the present embodiment can also be realized by a known printing technique such as offset printing or offset UV printing. In the case of gravure printing, printing can be performed using a known gravure printing machine. In addition, in the case of using another known printing technique, printing can be performed using a printing machine corresponding to the known printing technique.
　色インキ層印刷工程（Ｓ０１）では、原紙２１の上に色インキ層が印刷される。本実施形態では、色インキ層として第一インキ層２２及び第二インキ層２３が形成される。使用する色インキは、パッケージ１のデザインに応じて適宜選択される。次に、ＯＰニス加工工程（Ｓ０２）では、色インキ層（本実施形態では、第二インキ層２３）の表面にＯＰニス加工を施すことで、ＯＰニス層２４が形成される。ＯＰニス加工工程は、本発明の保護層印刷工程に相当する。形成されたＯＰニス層２４は、高輝度金属インキが用いられる領域以外の領域では最表層となる。 In the color ink layer printing step (S01), a color ink layer is printed on the base paper 21. In the present embodiment, the first ink layer 22 and the second ink layer 23 are formed as the color ink layer. The color ink to be used is appropriately selected according to the design of the package 1. Next, in the OP varnish processing step (S02), the OP varnish layer 24 is formed by performing OP varnish processing on the surface of the color ink layer (second ink layer 23 in the present embodiment). The OP varnish processing step corresponds to the protective layer printing step of the present invention. The formed OP varnish layer 24 is the outermost layer in a region other than the region where the high brightness metal ink is used.
　次に、高輝度金属インキが用いられる領域では、専用アンカー加工工程（Ｓ０３）において、ＯＰニス層２４の上にアンカーコート剤が塗布され、専用アンカー層２５が形成される。なお、本工程（専用アンカー加工工程）を省略し、ＯＰニス加工工程の次に後述する高輝度金属インキ層印刷工程を行うようにしてもよい。 Next, in the region where the high-intensity metal ink is used, an anchor coating agent is applied on the OP varnish layer 24 in the dedicated anchor processing step (S03), and the dedicated anchor layer 25 is formed. Note that this step (dedicated anchoring step) may be omitted, and a high-intensity metal ink layer printing step, which will be described later, may be performed after the OP varnishing step.
　高輝度金属インキ層印刷工程（Ｓ０４）では、専用アンカー層２５又はＯＰニス層２４の上に、高輝度金属インキの印刷が施され、高輝度金属インキ層２６が形成される。本実施形態では、金属インキとして蒸着アルミリーフィングタイプインキが用いられる。蒸着アルミリーフィングタイプインキは、例えば図８に示す方法で得られる。すなわち、容器（真空容器）内でアルミニウムを加熱して蒸発させ、アルミニウムから離れて配置された基板に蒸発したアルミニウムを付着させる。その後、基板に付着させたアルミニウム片を剥離し、剥離したアルミニウム片を色インキに混合する。銀は、蒸着アルミリーフィングタイプインキを単独で使用すればよい。金、赤いメタリック色、青いメタリック色は、蒸着アルミリーフィングタイプインキに、夫々、黄、赤、青等の色インキを混合すればよい。以上により、任意の色の蒸着アルミリーフィングタイプインキが得られる。 In the high brightness metal ink layer printing step (S04), the high brightness metal ink is printed on the dedicated anchor layer 25 or the OP varnish layer 24 to form the high brightness metal ink layer 26. In this embodiment, vapor deposition aluminum leafing type ink is used as metal ink. The vapor deposited aluminum leaf type ink is obtained by the method shown in FIG. 8, for example. That is, aluminum is heated and evaporated in a container (vacuum container), and the evaporated aluminum is adhered to a substrate disposed away from the aluminum. Thereafter, the aluminum piece adhered to the substrate is peeled off, and the peeled aluminum piece is mixed with the color ink. As for silver, vapor-deposited aluminum leaf type ink may be used alone. For gold, red metallic color, and blue metallic color, color inks such as yellow, red, and blue may be mixed with vapor-deposited aluminum leaf type ink, respectively. As described above, vapor deposition aluminum leafing type ink of any color can be obtained.
　次に、エンボス加工工程（ステップＳ０５）では、高輝度金属インキ層２６の表面にエンボス加工が施される。これにより、高輝度金属インキ層２６の表面が平滑化される。エンボス加工は、本発明に係る押し加工に相当する。エンボス加工に代えて、デボス加工、型押し加工を施してもよい。以上により、パッケージの印刷処理が終了する。 Next, in the embossing process (step S05), the surface of the high brightness metal ink layer 26 is embossed. Thereby, the surface of the high-intensity metal ink layer 26 is smoothed. The embossing corresponds to the pressing according to the present invention. Instead of embossing, debossing or embossing may be performed. Thus, the package printing process ends.
　＜効果＞
　以上説明した実施形態に係るパッケージ１は、高輝度金属インキを印刷する領域では、ＯＰニス層２４が高輝度金属インキ層２６の上層ではなく、高輝度金属インキ層２６の下層、すなわち下地として配置される。これにより、高輝度金属インキ層２６の上にＯＰニス層２４などの保護層を設けることで発生する輝度感の低下を回避することができる。その結果、輝度感を従来よりも向上することができる。また、本実施形態に係るパッケージ１では、高輝度金属インキ層２６の下方において、原紙２１の表面から順に、第一インキ層２２、第二インキ層２３が形成され、各層の表面が段階的に平滑化されている。更に第二インキ層２３の上にＯＰニス層２４が形成されることでより平滑化されている。このように高輝度金属インキ層２６は、下地処理が段階的に行われた上に形成されることから、輝度感を従来よりも向上することができる。また、ＯＰニス層２４と高輝度金属インキ層２６との間には、専用アンカー層２５が形成され、ＯＰニス層２４と高輝度金属インキ層２６との接着力が高められている。更に、高輝度金属インキ層２６の表面はエンボス加工が施されていることから、高輝度金属インキ層２６の表面も平滑化されている。その結果、高輝度金属インキ層２６の表面における乱反射が抑制され、輝度感がより向上する。 <Effect>
In the package 1 according to the embodiment described above, the OP varnish layer 24 is disposed not as an upper layer of the high-brightness metal ink layer 26 but as a lower layer of the high-brightness metal ink layer 26, that is, as a base in the region where the high-brightness metal ink is printed. Is done. Thereby, it is possible to avoid a decrease in luminance caused by providing a protective layer such as the OP varnish layer 24 on the high luminance metal ink layer 26. As a result, the luminance feeling can be improved as compared with the conventional case. In the package 1 according to the present embodiment, the first ink layer 22 and the second ink layer 23 are formed in order from the surface of the base paper 21 below the high brightness metal ink layer 26, and the surface of each layer is stepwise. Smoothed. Further, the OP varnish layer 24 is formed on the second ink layer 23, thereby further smoothing. As described above, the high-brightness metal ink layer 26 is formed after the base treatment is performed stepwise, and thus the brightness feeling can be improved as compared with the conventional case. In addition, a dedicated anchor layer 25 is formed between the OP varnish layer 24 and the high-brightness metal ink layer 26, and the adhesive force between the OP varnish layer 24 and the high-brightness metal ink layer 26 is enhanced. Further, since the surface of the high-brightness metal ink layer 26 is embossed, the surface of the high-brightness metal ink layer 26 is also smoothed. As a result, irregular reflection on the surface of the high-brightness metallic ink layer 26 is suppressed, and the brightness feeling is further improved.
