従来、偽造防止機能を有する印刷物としては、見る角度によって色彩が変化する色彩可変印刷層と、色彩可変印刷層の上に紫外線または赤外線の照射により蛍光発光する光反応印刷層をパターン状に設けた構成の印刷媒体（例えば、特許文献１参照）、あるいは、印刷箇所の少なくとも一部がパール顔料及び蛍光顔料を含む偽造防止用インキで印刷されており、同時に偽造防止用インキで使用されているパール顔料によるインキにて少なくとも一部が印刷されている偽造防止印刷物（例えば、特許文献２参照）等が知られている。 Conventionally, as a printed matter having an anti-counterfeit function, a color variable printing layer whose color changes depending on a viewing angle and a photoreactive printing layer that emits fluorescence by irradiation with ultraviolet rays or infrared rays are provided in a pattern on the color variable printing layer. A print medium having a structure (see, for example, Patent Document 1), or at least a part of the printed portion is printed with an anti-counterfeit ink containing a pearl pigment and a fluorescent pigment, and at the same time, the pearl used in the anti-counterfeit ink An anti-counterfeit printed matter (for example, see Patent Document 2) and the like at least partially printed with pigment ink is known.
しかしながら、前記印刷媒体あるいは偽造防止印刷物においては、パールインキを用いた印刷層上に蛍光インキによる印刷層が形成されているものであり、パールインキと蛍光インキの重ね刷りにより偽造防止効果を図るものであり、真偽判定には目視判定と例えば、ブラックライト等の器具を使用することによる判定が併用されるものである。 However, in the printing medium or the anti-counterfeit printed matter, a printing layer made of fluorescent ink is formed on a printing layer using pearl ink, and the anti-counterfeiting effect is achieved by overprinting the pearl ink and the fluorescent ink. In the true / false determination, visual determination and determination by using an instrument such as a black light are used in combination.
そこで本発明は、上記問題を解決すべくなされたものであり、その目的とするところは印刷物に備えた真偽判別領域に設けたパール印刷層により形成された例えばロゴ、マーク等の画像を見る角度を変えることにより目視で十分に読み取ることができ、かつ、カラーコピーされた画像が確実に判別不能または判別困難となる偽造防止機能を有する印刷物を提供するものである。 Accordingly, the present invention has been made to solve the above-described problems, and the object of the present invention is to view images such as logos and marks formed by a pearl print layer provided in a genuineness determination area provided in a printed material. It is an object of the present invention to provide a printed matter that can be sufficiently read visually by changing the angle and has a forgery prevention function that makes it difficult to distinguish or difficult to distinguish a color-copied image.
本発明は、上記課題を達成するためになされたものであり、請求項１記載の本発明は、真偽判別領域を有する基材の前記真偽判別領域の上に下地印刷層を設け、前記下地印刷層の上に見る角度により色が変化するパールインキからなるパール印刷層を備えた印刷物であって、前記パール印刷層が、ロゴ、マーク、数字、記号、図形、又は文字等の目視可能な画像部分として構成されており、前記下地印刷層がストライプ柄の目視可能な背景部分として構成されており、前記真偽判別領域内には前記下地印刷層からなる部分と、前記下地印刷層と前記パール印刷層が積層された部分と、前記パール印刷層からなる部分とが設けられていることを特徴とする印刷物である。 The present invention has been made in order to achieve the above-mentioned problem, and the present invention according to claim 1 is characterized in that a base printing layer is provided on the authenticity determination region of the base material having the authenticity determination region, Printed material with a pearl print layer made of pearl ink whose color changes depending on the angle seen on the base print layer, and the pearl print layer is visible for logos, marks, numbers, symbols, figures, characters, etc. The underprint layer is configured as a visually recognizable background portion of a stripe pattern, and the authenticity determination region includes a portion composed of the underprint layer, and the underprint layer. The printed matter is characterized in that a portion where the pearl print layer is laminated and a portion made of the pearl print layer are provided .
また、請求項２記載の本発明は、請求項１に記載の印刷物において、前記基材上には墨インキからなる印刷層が形成されており、前記下地印刷層が前記印刷層の前記墨インキで形成されていることを特徴とするものである。 According to a second aspect of the present invention, in the printed matter according to the first aspect, a printing layer made of black ink is formed on the substrate, and the base printing layer is the black ink of the printing layer. It is characterized by being formed by .
本発明の印刷物は、真偽判別領域を有する基材の前記真偽判別領域の上に下地印刷層を設け、前記下地印刷層の上に見る角度により色が変化するパールインキからなるパール印刷層を備えた構成とすることにより、下地印刷層が目止めとなり、基材表面を平滑にする効果とパール印刷層を形成するパールインキが基材に含浸することを防止する効果を奏し、パール印刷層で形成された画像がより鮮明に浮かび上がり、例えば、パール印刷層で形成されたロゴを見る角度を変えることにより容易に読み取ることができる。さらに、パール印刷層で形成された画像はカラーコピー機を用いて複写しても異なった色ないしはパールインキが有する光輝性が得られず目視画像を複写画像で再現することができないのでカラーコピー機による偽造防止が困難となる。 The printed matter of the present invention is a pearl print layer comprising a pearl ink in which a base print layer is provided on the authenticity discrimination region of a base material having a true / false discrimination region, and the color changes depending on an angle viewed on the base print layer. By using the structure, the base printing layer becomes a filler, and the effect of smoothing the substrate surface and the effect of preventing the pearl ink forming the pearl printing layer from being impregnated in the substrate are obtained. The image formed by the layers emerges more clearly and can be easily read, for example, by changing the viewing angle of the logo formed by the pearl print layer. Further, even if the image formed with the pearl printing layer is copied using a color copying machine, the different colors or the glittering properties of the pearl ink cannot be obtained, and the visual image cannot be reproduced with the copied image. It becomes difficult to prevent forgery.
また、請求項１に記載の本発明は、下地印刷層をストライプ柄とすることにより、真偽判別領域内には基材の上にパール印刷層のみの部分と、下地印刷層のみの部分と、下地印刷層の上にパール印刷層が積層された部分が少なくとも存在することとなり、それぞれの部分においてパール印刷層の色彩が異なり、そのコントラストにより真偽判別が目視で簡単にできる。 Further, the invention according to claim 1, by the underlying print layer and stripes, a portion of on the substrate pearl printing layer only true false determination area, the only portion of the underprint layer Then, at least a portion where the pearl printing layer is laminated on the base printing layer is present, and the color of the pearl printing layer is different in each portion, and the authenticity determination can be easily made visually by the contrast.
また、請求項２に記載の本発明は、基材上に形成された墨インキからなる印刷層と同じ墨インキで下地印刷層が形成されるので印刷の色数を増やすことなく墨インキからなる印刷層と下地印刷層を同時に形成できるので原価低減が図れる。 Further, the present invention according to claim 2 is made of black ink without increasing the number of printing colors because the base print layer is formed of the same black ink as the print layer made of black ink formed on the substrate. Since the printing layer and the base printing layer can be formed simultaneously, the cost can be reduced.

図１は本発明に係る印刷物の第一実施形態を示し、（イ）は平面図、（ロ）はＡ−Ａ線断面図である。図１に示すように本発明の印刷物１は基材１０上に真偽判別領域１１を有している。真偽判別領域１１は基材１０上の所定位置に設けられ、真偽判別領域１１には下地印刷層２０により四角形の下地柄２が形成され、その上にパール印刷層３０によりロゴ３が形成されている。第一実施形態の印刷物１は商品券の例を示しており、上部に商品券等の標題４、中央には商品券金額５、下部には発行会社名６、左側には地紋模様７が印刷されている。標題４、商品券金額５、発行会社名６、地紋模様７は通常、プロセスカラーインキを用いてオフセット印刷される。第一実施形態の標題４および発行会社名６は墨インキからなる印刷層４０で形成されている。本発明の印刷物１はカラーコピー機を用いて偽造されることを防止する機能が要求される用途に用いられ、第一実施形態に示す商品券以外に、図書券、株券、証券、ギフト券、株主優待券、チケットなどの金券類、各種証明書、重要書類等に使用できる。基材１０上に設けられる真偽判別領域１１の所定位置は、特に限定されるものではないが、一見して判る目立つ位置が望ましい。 1A and 1B show a first embodiment of a printed matter according to the present invention, in which FIG. 1A is a plan view and FIG. As shown in FIG. 1, the printed matter 1 of the present invention has a true / false discrimination region 11 on a substrate 10. The authenticity determination area 11 is provided at a predetermined position on the base material 10. In the authenticity determination area 11, a square base pattern 2 is formed by the base print layer 20, and a logo 3 is formed thereon by the pearl print layer 30. Has been. The printed matter 1 of the first embodiment shows an example of a gift certificate. The title 4 such as a gift certificate is printed at the top, the gift certificate amount 5 is printed at the center, the issuing company name 6 is printed at the bottom, and the background pattern 7 is printed on the left side. Has been. The title 4, gift certificate amount 5, issuing company name 6, and background pattern 7 are usually offset printed using process color ink. The title 4 and the issuing company name 6 in the first embodiment are formed of a printing layer 40 made of black ink. The printed matter 1 of the present invention is used for an application that requires a function to prevent forgery using a color copier, and besides the gift certificate shown in the first embodiment, a book certificate, stock certificate, securities, gift certificate, Can be used for shareholder coupons, tickets, and other certificates, various certificates, important documents, etc. The predetermined position of the authenticity discrimination region 11 provided on the base material 10 is not particularly limited, but a conspicuous position that can be seen at a glance is desirable.
真偽判別領域１１は図１（ロ）に示すように基材１０の上に下地印刷層２０とパール印刷層３０が順に積層された構成である。下地柄２を形成する下地印刷層２０はベタ印刷、グラデーション柄の印刷、ストライプ柄等で設けることができ、下地柄２は例えば動物やキャラクターや図形等の特定パターンが使用される。第一実施形態の印刷物１の下地印刷層２０はベタ印刷して設けられ四角形の下地柄２を形成している。下地印刷層２０を形成するインキは、光反射率の低い暗色系のインキを用いる方がパール印刷層の画像がより鮮明になり、また、カラーコピーした場合にはパール印刷層の画像再現が困難となるので好ましい。特に図１（イ）に示すように標題４や発行会社名６に墨インキを用いた場合、下地印刷層２０は同じ墨インキを用いて墨インキからなる印刷層４０として形成することが特に好ましい。 As shown in FIG. 1B, the authenticity discrimination area 11 has a configuration in which a base printing layer 20 and a pearl printing layer 30 are sequentially laminated on a base material 10. The base print layer 20 that forms the base pattern 2 can be provided by solid printing, gradation pattern printing, stripe pattern, or the like, and the base pattern 2 uses a specific pattern such as an animal, a character, or a figure. The ground printing layer 20 of the printed material 1 of the first embodiment is provided by solid printing to form a rectangular ground pattern 2. The ink used to form the base printing layer 20 uses a dark-colored ink with low light reflectance, so that the image of the pearl printing layer becomes clearer, and when the color copy is made, it is difficult to reproduce the image of the pearl printing layer. Therefore, it is preferable. In particular, as shown in FIG. 1A, when black ink is used for the title 4 or the issuing company name 6, it is particularly preferable that the base printing layer 20 is formed as a printing layer 40 made of black ink using the same black ink. .
下地印刷層２０の上に形成されるパール印刷層３０は、ロゴ、マーク、数字、記号、図形、文字等の特定パターンが用いられる。第一実施形態の印刷物１のパール印刷層３０はロゴ３が形成されている。パール印刷層３０は見る角度により色が変化するパールインキを用いてシルク印刷方式で下地印刷層２０の上に形成する。
パール印刷層３０を形成するためのパールインキとしては、屈折率の低い雲母やシリカ、アルミナと、屈折率の高い酸化ケイ素、酸化チタン、酸化スズ、酸化鉄などの金属酸化物とが層状配列された顔料を透明なビヒクル中に分散したものが使用できる。パールインキで印刷されたパール印刷層は、例えば、雲母と金属酸化物が組み合わされた多層膜になり、入射光は異なる屈折率を有する層の境界で多重反射し、また、反射光が相互に干渉することにより、パール特有の干渉色や高虹彩色と光沢が再現される。
The pearl print layer 30 formed on the base print layer 20 uses a specific pattern such as a logo, a mark, a number, a symbol, a figure, or a character. A logo 3 is formed on the pearl print layer 30 of the printed matter 1 of the first embodiment. The pearl printing layer 30 is formed on the base printing layer 20 by a silk printing method using pearl ink whose color changes depending on the viewing angle.
As the pearl ink for forming the pearl print layer 30, mica, silica, and alumina having a low refractive index and metal oxides such as silicon oxide, titanium oxide, tin oxide, and iron oxide having a high refractive index are layered. A pigment dispersed in a transparent vehicle can be used. A pearl print layer printed with pearl ink, for example, is a multilayer film in which mica and metal oxide are combined, and incident light is multiple-reflected at the boundary between layers having different refractive indexes, and reflected light is mutually reflected. By interference, the interference color peculiar to pearl, high iris color and gloss are reproduced.
図２は本発明に係る印刷物の第二実施形態を示す平面図である。第二実施形態の印刷物１Ａは、下地印刷層２０をグラデーション柄で設け、その上にパール印刷層３０を積層している。その他は第一実施形態と同じである。図２に示す下地印刷層２０の下地柄２は左から右の方向に向かって暗から明になるグラデーションを設けている。下地印刷層２０の下地柄２をグラデーションとすることにより、パール印刷層３０が下地のグラデーションに応じて色彩が変化し多彩に見えるのでより真偽判定が容易となる。なお、パール印刷層３０で形成されたロゴ３は下地印刷層２０と明確に表示するために白抜き文字で示す。 FIG. 2 is a plan view showing a second embodiment of the printed matter according to the present invention. In the printed matter 1A of the second embodiment, the base print layer 20 is provided with a gradation pattern, and the pearl print layer 30 is laminated thereon. Others are the same as the first embodiment. The ground pattern 2 of the ground printing layer 20 shown in FIG. 2 is provided with a gradation from dark to bright from the left to the right. By making the base pattern 2 of the base print layer 20 into a gradation, the pearl print layer 30 changes in color according to the base gradation and looks various, so that authenticity determination becomes easier. Note that the logo 3 formed with the pearl print layer 30 is indicated by white letters to clearly display the underprint layer 20.
図３は本発明に係る印刷物の第三実施形態を示し、（イ）は平面図、（ロ）はＢ−Ｂ線断面図である。図３に示すように第三実施形態の印刷物１Ｂは下地印刷層２０の下地柄２を画線部と非画線部からなるストライプ柄で設け、その上にパール印刷層３０を積層している。図３（ロ）に示すように真偽判別領域１１内にはストライプ柄の画線部のみが表出した下地印刷層からなる部分ＳＯと、下地印刷層２０のストライプ柄の画線部の上にパール印刷層３０が積層された状態の下地印刷層とパール印刷層が積層された部分ＳＰと、下地印刷層２０のストライプ柄の非画線部であり基材１０上にパール印刷層３０が直接形成された状態のパール印刷層からなる部分ＰＯとが設けられている。円内にその拡大図を示す。前記３つの部分ＳＯ、ＳＰ、ＰＯが確保できれば、ストライプ柄の画線部の線幅、線間隔（非画線部の線幅）、線の角度は任意に形成できる。真偽判別領域１１内にパール印刷層のみの部分（ＰＯ）と、下地印刷層のみの部分（ＳＯ）と、下地印刷層の上にパール印刷層が積層された部分（ＳＰ）を存在させることにより、それぞれの部分において色が異なって見え、そのコントラストにより容易に真偽判別が可能となる。さらに、カラーコピー機を用いて複写してもパール印刷層３０の画像が再現されず偽造防止効果がより得られるものとなる。 3A and 3B show a third embodiment of the printed matter according to the present invention, in which FIG. 3A is a plan view and FIG. As shown in FIG. 3, the printed matter 1 </ b> B according to the third embodiment is provided with the base pattern 2 of the base print layer 20 in a stripe pattern including an image line portion and a non-image line portion, and a pearl print layer 30 is laminated thereon. . As shown in FIG. 3B, in the authenticity determination area 11, a portion SO consisting of a base print layer in which only a stripe pattern image line portion is exposed, and an area above the stripe pattern image line portion of the base print layer 20. The pearl print layer 30 is a non-image portion of a stripe pattern of the base print layer 20 and the portion SP where the pearl print layer 30 and the pearl print layer are laminated. A portion PO made of a pearl print layer in a directly formed state is provided. The enlarged view is shown in the circle. If the three portions SO, SP, and PO can be secured, the line width, the line interval (line width of the non-image portion), and the line angle of the stripe pattern can be arbitrarily formed. In the authenticity discrimination area 11, there must be a part (PO) of only the pearl print layer, a part (SO) of only the base print layer, and a part (SP) in which the pearl print layer is laminated on the base print layer. Thus, colors appear different in each part, and authenticity determination can be easily performed by the contrast. Furthermore, even if copying is performed using a color copier, the image of the pearl print layer 30 is not reproduced, and a forgery prevention effect is further obtained.
図４は本発明に係る印刷物の第一実施形態をカラーコピー機で複写した複写物を示す平面図である。複写物１’では、パールインキからなるパール印刷層３０で形成されたロゴ３からなる特定パターンにおいて、パールインキの光輝性が失われ、色相もグレー系となったロゴ３’として複写物の基材１０’上に複写されている。すなわち、図１（イ）に示す印刷物１０と図４に示す複写物１’を比較して目視すればその違いに気付き即座に真偽判定ができる。 FIG. 4 is a plan view showing a copy obtained by copying the first embodiment of the print according to the present invention with a color copier.
