Description

長尺印刷物Long printed matter
　本発明は、長尺帯状のウェブにデザイン印刷部が長手方向に繰り返し表された長尺印刷物に関する。 The present invention relates to a long printed matter in which a design printed portion is repeatedly represented in the longitudinal direction on a long strip-shaped web.
　一般に、ラベル、包装材、ラッピングリボンなどのシート物は、長尺印刷物を切断することによって得られる。このような長尺印刷物は、通常、長尺帯状のウェブと、前記ウェブの長手方向に繰り返して印刷された複数のデザイン印刷部と、を有する。前記デザイン印刷部は、各種の印刷法によってウェブにインキを印刷することによって形成される。印刷法としては、凸版印刷法と凹版印刷法に大別できる。 Generally, sheets such as labels, packaging materials, and wrapping ribbons are obtained by cutting long printed matter. Such a long printed matter usually has a long strip-shaped web and a plurality of design printing portions repeatedly printed in the longitudinal direction of the web. The design printing unit is formed by printing ink on the web by various printing methods. The printing method can be roughly divided into a letterpress printing method and an intaglio printing method.
　凸版印刷法は、コスト的に比較的安価であり、さらに、様々な材質或いは厚みのウェブに対する印刷適性に優れている。凸版印刷法としては、フレキソ印刷法、凸版輪転印刷法などの印刷方式が挙げられ、特に、長尺印刷物を凸版印刷法にて形成する場合には、フレキソ印刷法が多用されている。 The letterpress printing method is relatively inexpensive in terms of cost, and is also excellent in printability for webs of various materials and thicknesses. Examples of the letterpress printing method include printing methods such as a flexographic printing method and a letterpress rotation printing method. In particular, when a long printed matter is formed by the letterpress printing method, the flexographic printing method is often used.
　フレキソ印刷法は、円筒状の版胴とその版胴の周囲に巻き付けたシート状の印刷版とを有する円筒状版を用いてフレキソインキを印刷する方式である。前記印刷版は凸版を有する。その印刷版を有する円筒状版を回転させ且つその版の表面にウェブを接触させることにより、インキが凸版からウェブに転写されてデザイン印刷部が形成される。 The flexographic printing method is a method of printing flexographic ink using a cylindrical plate having a cylindrical plate cylinder and a sheet-shaped printing plate wound around the plate cylinder. The printing plate has a letterpress. By rotating the cylindrical plate having the printing plate and bringing the web into contact with the surface of the plate, the ink is transferred from the letterpress to the web to form a design printing portion.
　フレキソ印刷などの凸版印刷法にあっては、円筒状版の回転に従い、円筒状版の表面のウェブへの接触（凸版がウェブに接触）と円筒状版の表面のウェブへの非接触（凸版を有さない凹部においてウェブから離れる）とが交互に繰り返される。このため、円筒状版が振動し、いわゆるバウンシングを生じ、インキの転写不良箇所が生じ得る。インキの転写不良箇所は、印刷がぼやけてしまうので、その改善が求められる。 In letterpress printing methods such as flexographic printing, the surface of the cylindrical plate is in contact with the web (the letterpress is in contact with the web) and the surface of the cylindrical plate is not in contact with the web (toppan) according to the rotation of the cylindrical plate. (Leave away from the web in the recesses that do not have) and so on are repeated alternately. Therefore, the cylindrical plate vibrates, so-called bouncing occurs, and ink transfer defects may occur. Printing is blurred at areas where ink transfer is poor, so improvement is required.
　特許文献１には、画像部と非画像部とを有し、前記画像部の印刷方向の先端側から０．５ｍｍ～５ｍｍまでの領域が、その領域以外の前記画像部の高さよりも低い低層化領域であり、前記低層化領域が前記印刷方向において非画像部に向かって漸次低くなっているフレキソ印刷版を用いることが開示されている。特許文献１には、前記フレキソ印刷版を用いることにより、バウンシングを抑制でき、ムラのない画像を印刷できると記載されている。 Patent Document 1 has an image portion and a non-image portion, and a low layer in which a region from the tip end side of the image portion in the printing direction to 0.5 mm to 5 mm is lower than the height of the image portion other than the region. It is disclosed that a flexographic printing plate is used, which is a modified region, and the low-layer region is gradually lowered toward a non-image portion in the printing direction. Patent Document 1 describes that by using the flexographic printing plate, bouncing can be suppressed and an even image can be printed.

　技術の多様性の見地から、凸版印刷によってデザインを表す場合に、特許文献１とは異なる手段によって、デザイン印刷部が綺麗に表されている長尺印刷物が望まれる。 From the viewpoint of the variety of technologies, when expressing a design by letterpress printing, a long printed matter in which the design printed portion is clearly represented by a means different from Patent Document 1 is desired.
　本発明の目的は、凸版印刷によってデザイン印刷部の画像が綺麗に表された長尺印刷物を提供することである。 An object of the present invention is to provide a long printed matter in which the image of the design printing section is clearly represented by letterpress printing.
　本発明の長尺印刷物は、長尺帯状のウェブと、前記ウェブの長手方向に繰り返して凸版印刷された複数のデザイン印刷部からなるデザイン列であって、前記ウェブの短手方向に２列以上配置されたデザイン列と、任意の１つの前記デザイン列に隣接して配置され且つ長手方向に延びるベアラーバー印刷部と、を有し、前記デザイン印刷部が、第１インキを凸版印刷した第１インキ印刷部と、第２インキを凸版印刷した第２インキ印刷部と、を有し、前記ベアラーバー印刷部が、前記第１インキを凸版印刷した第１バー部と、前記第２インキを凸版印刷した第２バー部と、を有し、前記第１バー部の幅が、第２バー部の幅よりも大きい。 The long printed matter of the present invention is a design row consisting of a long strip-shaped web and a plurality of design printing portions repeatedly letterpressed in the longitudinal direction of the web, and two or more rows in the lateral direction of the web. A first ink having an arranged design row and a bearer bar printing portion arranged adjacent to any one of the design rows and extending in the longitudinal direction, the design printing portion printing the first ink on a letterpress. It has a printing unit and a second ink printing unit on which the second ink is letterpress-printed, and the bearer bar printing unit prints the first bar portion on which the first ink is letterpressed and the second ink on a letterpress. It has a second bar portion, and the width of the first bar portion is larger than the width of the second bar portion.
　本発明の好ましい長尺印刷物は、前記第１インキ印刷部が、背景印刷部であり、前記第２インキ印刷部が、文字を含む画像を表した印刷部である。 In the preferred long printed matter of the present invention, the first ink printing unit is a background printing unit, and the second ink printing unit is a printing unit representing an image including characters.
　本発明の好ましい長尺印刷物は、前記ウェブが、熱収縮性を有する透明なシートからなり、前記デザイン列において、長手方向に隣接する各デザイン印刷部の間に、デザイン印刷部を有さない非画像部が短手方向に延在されている。 In a preferred long printed matter of the present invention, the web is made of a heat-shrinkable transparent sheet, and there is no design printing portion between each design printing portion adjacent in the longitudinal direction in the design row. The image part extends in the lateral direction.
　本発明の好ましい長尺印刷物は、前記ベアラーバー印刷部が、短手方向に隣接する２つのデザイン列の間に配置されている。 In the preferred long printed matter of the present invention, the bearer bar printing portion is arranged between two design rows adjacent to each other in the lateral direction.
　本発明の好ましい長尺印刷物は、前記第１バー部と第２バー部が、重ねられており、前記第２バー部の単位面積あたりのインキ付着量が、第１バー部の単位面積あたりのインキ付着量よりも小さい。 In a preferable long printed matter of the present invention, the first bar portion and the second bar portion are overlapped with each other, and the amount of ink adhered per unit area of the second bar portion is per unit area of the first bar portion. It is smaller than the amount of ink adhered.
　本発明によれば、円筒状版にてデザイン印刷部を凸版印刷する際にインキ抜けを抑制できるので、凸版印刷によってデザイン印刷部の画像が綺麗に表された長尺印刷物を提供できる。 According to the present invention, since ink loss can be suppressed when the design printing portion is letterpress printed on the cylindrical plate, it is possible to provide a long printed matter in which the image of the design printing portion is clearly represented by the letterpress printing.

＜長尺印刷物の概要＞
　図１は、長尺印刷物Ａを表面側から見た図である。図２は、長尺印刷物Ａを裏面側から見た図であり、図３は、図２の一部分を拡大した平面図であり、図４は、図３のＩＶ－ＩＶ線で切断した断面図であり、図５は、図３のＶ－Ｖ線で切断した断面図である。 <Overview of long printed matter>
FIG. 1 is a view of the long printed matter A viewed from the front surface side. FIG. 2 is a view of the long printed matter A viewed from the back surface side, FIG. 3 is an enlarged plan view of a part of FIG. 2, and FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG. 5 is a cross-sectional view taken along the line VV of FIG.
　図１において、長尺印刷物Ａは、平面視で長尺帯状である。本明細書において、長尺帯状は、長手方向長さが短手方向よりも十分に長い平面視略長方形状をいう。前記短手方向は、長手方向と直交する方向である。長尺帯状の長手方向長さとしては、例えば、５ｍ以上、好ましくは１０ｍ以上である。 In FIG. 1, the long printed matter A has a long strip shape in a plan view. In the present specification, the long strip shape refers to a substantially rectangular shape in a plan view in which the length in the longitudinal direction is sufficiently longer than that in the lateral direction. The lateral direction is a direction orthogonal to the longitudinal direction. The length in the longitudinal direction of the long strip is, for example, 5 m or more, preferably 10 m or more.
　長尺印刷物Ａは、長尺帯状のウェブ１と、ウェブ１に形成された印刷部と、を有する。ここで、本明細書において、印刷部は、ウェブ１にインキを凸版印刷してなるインキ固化部からなる。印刷部は、デザイン印刷部２と、ウェブ１の長手方向に帯状に延びるベアラーバー印刷部３と、を含む。デザイン印刷部２は、画像（デザイン）を表した印刷部であり、ベアラーバー印刷部３は、凸版印刷する際にベアラー凸版がウェブ１に接触することによって形成される印刷部である。 The long printed matter A has a long strip-shaped web 1 and a printed portion formed on the web 1. Here, in the present specification, the printing unit includes an ink solidifying unit formed by letterpress printing ink on the web 1. The printing unit includes a design printing unit 2 and a bearer bar printing unit 3 extending in a strip shape in the longitudinal direction of the web 1. The design printing unit 2 is a printing unit representing an image (design), and the bearer bar printing unit 3 is a printing unit formed by the bearer letterpress plate coming into contact with the web 1 during letterpress printing.
　デザイン印刷部２は、ウェブ１の長手方向に繰り返して凸版印刷されており、従って、複数のデザイン印刷部２が長手方向に配置されている。この長手方向に並んだ複数のデザイン印刷部２からなる列（デザイン列）は、ウェブ１の短手方向に２列以上配置されている。ベアラーバー印刷部３は、任意の１つのデザイン列に隣接して配置されている。 The design printing section 2 is repeatedly letterpress printed in the longitudinal direction of the web 1, and therefore, a plurality of design printing sections 2 are arranged in the longitudinal direction. Two or more rows (design rows) composed of the plurality of design printing units 2 arranged in the longitudinal direction are arranged in the lateral direction of the web 1. The bearer bar printing unit 3 is arranged adjacent to any one design row.
　デザイン印刷部２は、第１インキを凸版印刷した第１インキ印刷部２１と、第２インキを凸版印刷した第２インキ印刷部２２と、を有する。ベアラーバー印刷部３は、第１インキを凸版印刷した第１バー部３１と、第２インキを凸版印刷した第２バー部３２と、を有し、第１バー部３１の幅が、第２バー部３２の幅よりも大きい。第１バー部３１や第２バー部３２などのバー部の幅は、短手方向における長さをいう。 The design printing unit 2 includes a first ink printing unit 21 in which the first ink is letterpress printed, and a second ink printing unit 22 in which the second ink is letterpress printed. The bearer bar printing section 3 has a first bar section 31 on which the first ink is letterpress printed and a second bar section 32 on which the second ink is letterpress printed, and the width of the first bar section 31 is the second bar. It is larger than the width of the portion 32. The width of the bar portion such as the first bar portion 31 and the second bar portion 32 refers to the length in the lateral direction.
＜ウェブ＞
　ウェブ１は、柔軟性並びに適宜な強度及び剛性を有するものであれば特に限定されず、例えば、合成樹脂製シート、発泡樹脂シート、紙、合成紙、不織布、及びこれらが２層以上積層された積層シートなどが挙げられる。さらに、合成樹脂製シート、紙又は積層シートなどに、金属蒸着膜などのガス及び／又は光バリア層が積層されているものをウェブ１として用いてもよい。なお、シートという用語には、一般にフィルムと呼ばれるものも含まれる。合成樹脂製シートなどの材質は特に限定されず、例えば、ポリエチレン、ポリプロピレン、環状オレフィン、ポリエチレンを含む共重合ポリマーなどのポリオレフィン系、ポリエチレンテレフタレート、ポリ乳酸などのポリエステル系、ポリアミド系、ポリスチレン系などが挙げられる。 <Web>
The web 1 is not particularly limited as long as it has flexibility and appropriate strength and rigidity. For example, a synthetic resin sheet, a foamed resin sheet, paper, synthetic paper, a non-woven fabric, and two or more layers thereof are laminated. Laminated sheets and the like can be mentioned. Further, a web 1 in which a gas and / or optical barrier layer such as a metal vapor deposition film is laminated on a synthetic resin sheet, paper or a laminated sheet may be used. The term sheet also includes what is generally called a film. The material of the synthetic resin sheet and the like is not particularly limited, and examples thereof include polyethylene, polypropylene, cyclic olefins, polyolefin-based materials such as copolymer polymers containing polyethylene, polyester-based materials such as polyethylene terephthalate and polylactic acid, polyamide-based materials, and polystyrene-based materials. Can be mentioned.
　また、ウェブ１は、熱収縮性及び／又は自己伸縮性を有するものでもよく、或いは、実質的に熱収縮性及び自己伸縮性を有さないものでもよい。熱収縮性は、所定温度（例えば、７０℃～１００℃）に加熱されることによって収縮する性質をいう。自己伸縮性は、引っ張り力を加えることによって伸張し、その後、引っ張り力を解除することによってほぼ元の状態に復元する性質をいう。なお、実質的に熱収縮性を有さないウェブ１としては、例えば、長手方向及び短手方向のそれぞれの熱収縮率が５％以下のシート、好ましくは同熱収縮率が３％以下のシートが挙げられる。 Further, the web 1 may have heat shrinkage and / or self-stretchability, or may have substantially no heat shrinkage and self-stretchability. Heat shrinkability refers to the property of shrinking when heated to a predetermined temperature (for example, 70 ° C to 100 ° C). Self-stretching refers to the property of stretching by applying a tensile force and then restoring to almost the original state by releasing the tensile force. As the web 1 having substantially no heat shrinkage, for example, a sheet having a heat shrinkage rate of 5% or less in each of the longitudinal direction and the lateral direction, preferably a sheet having the same heat shrinkage rate of 3% or less. Can be mentioned.
　熱収縮性及び／又は自己伸縮性を有するシートをウェブ１として用いる場合、そのシートは、短手方向に熱収縮及び／又は自己伸縮するものでもよく、或いは、長手方向に熱収縮及び／又は自己伸縮するものでもよく、或いは、短手方向及び長手方向に熱収縮及び／又は自己伸縮するものでもよい。また、そのウェブ１は、短手方向に主として熱収縮及び／又は自己伸縮するものでもよく、或いは、長手方向に熱収縮及び／又は自己伸縮するものでもよく、或いは、短手方向及び長手方向に同等に熱収縮及び／又は自己伸縮するものでもよい。 When a heat-shrinkable and / or self-stretchable sheet is used as the web 1, the sheet may be heat-shrinkable and / or self-expandable in the lateral direction, or heat-shrink and / or self in the longitudinal direction. It may be stretchable, or it may be heat-shrinkable and / or self-stretchable in the lateral and longitudinal directions. Further, the web 1 may be mainly heat-shrinkable and / or self-expandable in the lateral direction, may be heat-shrinkable and / or self-expandable in the longitudinal direction, or may be heat-shrinkable and / or self-expandable in the longitudinal direction, or in the lateral direction and the longitudinal direction. It may be similarly heat-shrinkable and / or self-expanding.
　図示例では、短手方向に主として熱収縮するウェブ１が用いられている。かかるウェブ１の主たる熱収縮方向（例えば短手方向）の熱収縮率は、特に限定されないが、比較的大きな径差を有する被着体にも良好に熱収縮装着できる点から、好ましくは２０％以上であり、より好ましくは３０％以上であり、さらに好ましくは４０％以上である。前記ウェブ１は、主たる熱収縮方向に対して直交する方向（例えば長手方向）に熱変化するものでもよく、その方向における熱収縮率は、例えば、－３～１５％であり、好ましくは１～１０％である。前記熱収縮率のマイナスは、熱伸長を意味する。 In the illustrated example, the web 1 that mainly heat-shrinks in the lateral direction is used. The heat shrinkage rate of the web 1 in the main heat shrinkage direction (for example, the short side direction) is not particularly limited, but is preferably 20% from the viewpoint that the heat shrinkage can be satisfactorily attached to an adherend having a relatively large diameter difference. The above is more preferably 30% or more, still more preferably 40% or more. The web 1 may be thermally changed in a direction orthogonal to the main heat shrinkage direction (for example, a longitudinal direction), and the heat shrinkage rate in that direction is, for example, -3 to 15%, preferably 1 to 1 to 1. It is 10%. The minus of the heat shrinkage rate means heat elongation.
　ただし、本明細書において、熱収縮率は、加熱前（標準状態下で２４時間保存）のウェブ１の長さ（元の長さ）と、９０℃温水中に１０秒間浸漬して取り出した後のウェブ１の長さ（浸漬後の長さ）と、をそれぞれ標準状態下で計測し、下記式に代入して求められる。なお、各ウェブ１の長さは、標準状態下で計測する。標準状態は、２３℃、１気圧、５０％ＲＨをいう。
　熱収縮率（％）＝［｛（長手方向（又は短手方向）の元の長さ）－（長手方向（又は短手方向）の浸漬後の長さ）｝／（長手方向（又は短手方向）の元の長さ）］×１００。 However, in the present specification, the heat shrinkage is the length (original length) of the web 1 before heating (stored for 24 hours under standard conditions) and after being immersed in warm water at 90 ° C. for 10 seconds and taken out. The length of the web 1 (the length after immersion) is measured under standard conditions, and is obtained by substituting it into the following equation. The length of each web 1 is measured under standard conditions. Standard conditions are 23 ° C, 1 atm, and 50% RH.
Heat shrinkage rate (%) = [{(original length in the longitudinal direction (or the lateral direction))-(length after immersion in the longitudinal direction (or the lateral direction))} / (longitudinal direction (or the lateral direction) Direction) Original length)] x 100.
　ウェブ１の厚みは、特に限定されず、例えば、８μｍ～５００μｍであり、好ましくは、１０μｍ～２００μｍである。例えば、合成樹脂製シート、合成紙及びこれらを含む積層シートなどからなるウェブ１の厚みは、８μｍ～２００μｍであり、好ましくは、１０μｍ～１２０μｍである。 The thickness of the web 1 is not particularly limited, and is, for example, 8 μm to 500 μm, preferably 10 μm to 200 μm. For example, the thickness of the web 1 made of a synthetic resin sheet, synthetic paper, a laminated sheet containing these, and the like is 8 μm to 200 μm, preferably 10 μm to 120 μm.
　また、ウェブ１は、透明又は不透明のいずれでもよい。本明細書において、透明は、有色透明又は無色透明という意味である。好ましくは透明なウェブ１が用いられ、より好ましくは無色透明なウェブ１が用いられる。上記例示した中で、透明なウェブ１としては、合成樹脂製シート、合成樹脂製シートと透明な別のシートとの積層シートなどが挙げられる。 Further, the web 1 may be transparent or opaque. As used herein, transparent means colored transparent or colorless transparent. A transparent web 1 is preferably used, and more preferably a colorless and transparent web 1 is used. Among the above examples, examples of the transparent web 1 include a synthetic resin sheet, a laminated sheet of a synthetic resin sheet and another transparent sheet, and the like.
　ここで、透明（有色透明又は無色透明）は、対象物の裏面側に、その裏面から１ｃｍ離れた箇所に、白地の紙に黒色インキで任意の数字（大きさ１２ポイント）を印刷したものを配置し、前記対象物を透かしてその数字を表面側から識別できる状態をいう。不透明は、前記と同じ条件で裏面側に配置した数字を対象物の表面側から視認できない状態（数字を認識できない状態）をいう。透明（無色透明又は有色透明）の指標としては、例えば、全光線透過率などを用いて表すことができる。透明（無色透明又は有色透明）の指標としては、例えば、全光線透過率が７０％以上であり、好ましくは８０％以上であり、より好ましくは９０％以上である。ただし、全光線透過率は、透明である測定対象（透明なウェブ１である場合にはそのウェブ１が測定対象、透明な印刷部である場合には、前記透明なウェブ１に透明な印刷層を設けたものが測定対象）を、ＪＩＳ　Ｋ　７３６１（プラスチック－透明材料の全光線透過率の試験方法）に準拠した測定法によって測定される値をいう。 Here, transparent (colored transparent or colorless transparent) is a white paper printed with an arbitrary number (12 points in size) on the back side of the object at a distance of 1 cm from the back side. It refers to a state in which the object is arranged and the number can be identified from the surface side through the object. Opaque refers to a state in which the numbers arranged on the back surface side under the same conditions as described above cannot be visually recognized from the front surface side of the object (a state in which the numbers cannot be recognized). As an index of transparency (colorless transparency or colored transparency), for example, total light transmittance can be used. As an index of transparency (colorless transparency or colored transparency), for example, the total light transmittance is 70% or more, preferably 80% or more, and more preferably 90% or more. However, the total light transmittance is a transparent measurement target (in the case of a transparent web 1, the web 1 is a measurement target, and in the case of a transparent printing portion, the transparent web 1 is covered with a transparent print layer. Is a value measured by a measurement method based on JIS K 7361 (test method for total light transmittance of plastic-transparent material).
＜デザイン印刷部＞
　デザイン印刷部２は、纏まりある任意の画像（デザイン）を１つのデザインパターンとし、そのデザインパターンが、ウェブ１の長手方向に繰り返して印刷されている。その長手方向に並んだ複数のデザイン印刷部２を「列」とすると、デザイン印刷部２は、ウェブ１の短手方向に１列だけ設けられていてもよいが、通常、短手方向に２列以上（複数列）設けられる。デザイン列は、ウェブ１の短手方向に２列以上有していればよく、好ましくは、３列以上、より好ましくは、４列以上配置される。デザイン列の列数の上限は、特に制限はなく、ウェブ１の短手方向長さとデザイン印刷部２の短手方向長さとの関係で決定される。図示例では、便宜上、短手方向において４列のデザイン列が設けられた長尺印刷物Ａを表している。 <Design printing department>
The design printing unit 2 uses a set of arbitrary images (designs) as one design pattern, and the design pattern is repeatedly printed in the longitudinal direction of the web 1. Assuming that a plurality of design printing units 2 arranged in the longitudinal direction are "rows", the design printing units 2 may be provided in only one row in the lateral direction of the web 1, but usually 2 in the lateral direction. More than one row (multiple rows) is provided. The design rows may have two or more rows in the lateral direction of the web 1, preferably three or more rows, and more preferably four or more rows. The upper limit of the number of design columns is not particularly limited, and is determined by the relationship between the lateral length of the web 1 and the lateral length of the design printing unit 2. In the illustrated example, for convenience, a long printed matter A in which four rows of design rows are provided in the lateral direction is represented.
　デザイン印刷部２は、図１に示すように、ウェブ１の表面側から画像（デザイン）が視認できるように、ウェブ１の表面又は／及び裏面に設けられている。なお、ベアラーバー印刷部３も同様である。図１において、ウェブ１の表面側から見たときに視認できる、デザイン印刷部２及びベアラーバー印刷部３を実線で表している。ウェブ１が透明である場合、デザイン印刷部２は、ウェブ１の表面及び裏面の少なくともいずれか一方に設けられる。ウェブ１が不透明である場合、デザイン印刷部２は、ウェブ１の少なくとも表面（表面のみ又は表面及び裏面）に設けられる。なお、ベアラーバー印刷部３は、後述する製法から、デザイン印刷部２と同じ面に形成される。図示例では、透明なウェブ１の裏面にデザイン印刷部２及びベアラーバー印刷部３が設けられている。 As shown in FIG. 1, the design printing unit 2 is provided on the front surface and / or the back surface of the web 1 so that the image (design) can be visually recognized from the front surface side of the web 1. The same applies to the bearer bar printing unit 3. In FIG. 1, the design printing unit 2 and the bearer bar printing unit 3 that can be visually recognized when viewed from the surface side of the web 1 are represented by solid lines. When the web 1 is transparent, the design printing unit 2 is provided on at least one of the front surface and the back surface of the web 1. When the web 1 is opaque, the design printing section 2 is provided on at least the front surface (front surface only or front surface and back surface) of the web 1. The bearer bar printing unit 3 is formed on the same surface as the design printing unit 2 by a manufacturing method described later. In the illustrated example, the design printing section 2 and the bearer bar printing section 3 are provided on the back surface of the transparent web 1.
　上述のように、各デザイン列において、複数のデザイン印刷部２がウェブ１の長手方向に配置されているが、長手方向において隣接するデザイン印刷部２は、連続していてもよく、或いは、長手方向に所定間隔を開けて配置されていてもよい。図示例では、長手方向において隣接するデザイン印刷部２は、連続しておらず、所定間隔を開けて配置されている。従って、デザイン列において、長手方向に隣接する各デザイン印刷部２の間に、デザイン印刷部２を有さない非画像部２ａが短手方向に延在されている。この非画像部２ａは、短手方向に延びる帯状であり、ウェブ１が透明である場合には、透明部となる。 As described above, in each design row, a plurality of design printing units 2 are arranged in the longitudinal direction of the web 1, but the design printing portions 2 adjacent to each other in the longitudinal direction may be continuous or longitudinal. They may be arranged at predetermined intervals in the direction. In the illustrated example, the design printing units 2 adjacent to each other in the longitudinal direction are not continuous and are arranged at predetermined intervals. Therefore, in the design row, the non-image portion 2a having no design printing portion 2 extends in the lateral direction between the design printing portions 2 adjacent to each other in the longitudinal direction. The non-image portion 2a has a strip shape extending in the lateral direction, and when the web 1 is transparent, it becomes a transparent portion.
　また、各デザイン列において、ウェブ１の短手方向において隣接するデザイン印刷部２は、連続していてもよく、或いは、短手方向に所定間隔を開けて配置されていてもよい。図示例では、短手方向において隣接するデザイン印刷部２は、連続しておらず、所定間隔を開けて配置されている。従って、短手方向に隣接する各デザイン印刷部２の間に、デザイン印刷部２を有さない非画像部２ｂが長手方向に延在されている。この非画像部２ｂは、長手方向に延びる帯状であり、ウェブ１が透明である場合には、透明部となる。以下、短手方向の延びる帯状の非画像部２ａを短手非画像部２ａといい、長手方向の延びる帯状の非画像部２ｂを長手非画像部２ｂという。 Further, in each design row, the design printing units 2 adjacent to each other in the lateral direction of the web 1 may be continuous or may be arranged at predetermined intervals in the lateral direction. In the illustrated example, the design printing units 2 adjacent to each other in the lateral direction are not continuous and are arranged at predetermined intervals. Therefore, a non-image portion 2b having no design printing portion 2 extends in the longitudinal direction between the design printing portions 2 adjacent to each other in the lateral direction. The non-image portion 2b has a strip shape extending in the longitudinal direction, and becomes a transparent portion when the web 1 is transparent. Hereinafter, the strip-shaped non-image portion 2a extending in the lateral direction is referred to as a short non-image portion 2a, and the strip-shaped non-image portion 2b extending in the longitudinal direction is referred to as a longitudinal non-image portion 2b.
　短手非画像部２ａの幅（短手非画像部２ａの長手方向における長さ）及び長手非画像部２ｂの幅（長手非画像部２ｂの短手方向における長さ）は、それぞれ独立して、特に限定されず、適宜設定される。短手非画像部２ａの幅は、例えば、３ｍｍ～１０ｍｍであり、長手非画像部２ｂの幅は、例えば、１ｍｍ～１０ｍｍである。 The width of the short non-image portion 2a (the length of the short non-image portion 2a in the longitudinal direction) and the width of the longitudinal non-image portion 2b (the length of the longitudinal non-image portion 2b in the lateral direction) are independent of each other. , Is not particularly limited, and is set as appropriate. The width of the short non-image portion 2a is, for example, 3 mm to 10 mm, and the width of the longitudinal non-image portion 2b is, for example, 1 mm to 10 mm.
　デザイン印刷部２は、２種以上の異なるインキによって形成されている。デザイン印刷部２（及びベアラーバー印刷部３）を構成するインキは、任意の色彩を呈するカラーインキである。上述のように、デザイン印刷部２は、第１インキを凸版印刷した第１インキ印刷部２１と、第２インキを凸版印刷した第２インキ印刷部２２と、を有する。第１インキと第２インキは、異なるインキである。ここで、異なるインキとは、後述する製法においてデザイン印刷部２を形成する際に、異なる円筒状版にて凸版印刷されるインキを意味する。異なるインキは、色彩及び／又は組成が異なっていてもよく、或いは、色彩及び組成が同じであってもよい。通常、異なるインキは、色彩が異なるインキであり（色違いインキ）、このような色彩が異なるインキは、一般的にはその組成も異なる。 The design printing unit 2 is formed of two or more different inks. The ink constituting the design printing unit 2 (and the bearer bar printing unit 3) is a color ink exhibiting an arbitrary color. As described above, the design printing unit 2 includes a first ink printing unit 21 in which the first ink is letterpress-printed, and a second ink printing unit 22 in which the second ink is letterpress-printed. The first ink and the second ink are different inks. Here, the different inks mean inks that are letterpress printed on different cylindrical plates when the design printing unit 2 is formed in the manufacturing method described later. Different inks may have different colors and / or compositions, or may have the same color and composition. Usually, different inks are inks having different colors (different color inks), and such inks having different colors generally have different compositions.
　デザイン印刷部２は、第１インキの固化部である第１インキ印刷部２１と、第２インキの固化部である第２インキ印刷部２２と、を有していることを条件として、さらに、これらと異なるインキを凸版印刷した印刷部を有していてもよい。より装飾性に優れたデザインを表す観点から、デザイン印刷部２は、３種以上の異なるインキを凸版印刷して形成されていることが好ましく、４種以上の異なるインキを凸版印刷して形成されていることがより好ましい。図示例では、デザイン印刷部２は、５種の異なるインキによって形成されている。以下、５種のインキ及びそれらを凸版印刷して形成された印刷部を、第１乃至第５インキ及び第１乃至第５インキ印刷部２１乃至２５という。 The design printing unit 2 further includes a first ink printing unit 21 which is a solidifying unit of the first ink and a second ink printing unit 22 which is a solidifying unit of the second ink. It may have a printing unit in which ink different from these is printed on a letterpress. From the viewpoint of expressing a more decorative design, the design printing unit 2 is preferably formed by letterpress printing of three or more different inks, and is formed by letterpress printing of four or more different inks. Is more preferable. In the illustrated example, the design printing unit 2 is formed of five different inks. Hereinafter, the five types of ink and the printing unit formed by letterpress printing of the five types of ink are referred to as the first to fifth inks and the first to fifth ink printing units 21 to 25.
　デザイン印刷部２に表される画像（デザイン）は、特に限定されず、任意である。デザイン印刷部２に表される画像は、大別して、（１）何らかの観念を視覚的に識別できる画像（以下、観念を視覚的に識別できる画像を特に「標示」という）、（２）何らかの観念を視覚的に識別できない画像（以下、前記標示との対比から「非標示」という）、に分けられる。 The image (design) represented by the design printing unit 2 is not particularly limited and is arbitrary. The images represented by the design printing unit 2 are roughly classified into (1) an image that can visually identify an idea (hereinafter, an image that can visually identify an idea is particularly referred to as a "marking"), and (2) some idea. Is divided into images that cannot be visually identified (hereinafter, referred to as "non-marked" in comparison with the above-mentioned marking).
前記標示としては、文字、記号、絵柄などが挙げられる。前記絵柄としては、看者が何らかの観念を視覚的に識別できるものであり、例えば、山の柄、花の柄、クリスタルカット模様、波模様、インキ付着量の差によって表されたグラデーション模様など、様々なものが挙げられる。 Examples of the marking include characters, symbols, and patterns. The pattern is such that the viewer can visually identify some idea, for example, a mountain pattern, a flower pattern, a crystal cut pattern, a wave pattern, a gradation pattern represented by a difference in the amount of ink adhered, and the like. There are various things.
　前記非標示としては、無模様一色のベタ状の画像が挙げられる。前記ベタ状は、インキ固化部が面方向に延在して１つの連続した層を成していることをいう。ただし、印刷法にて形成されるベタ状の画像は、ドット状に付着し且つ固化したインキの集合物から構成されるので、巨視的に見ると、そのインキ固化部が面方向に延在して１つの連続した層を成しているが、微視的に見ると、その面内に無数の微細な隙間が存在する場合があることに留意されたい。このように微視的に見ると、微細な隙間を有する場合でも、巨視的に１つの連続した層を成している場合には、ベタ状の範疇に含まれるものとする。 Examples of the non-marking include a solid image with no pattern and one color. The solid shape means that the solidified ink portion extends in the plane direction to form one continuous layer. However, since the solid image formed by the printing method is composed of an aggregate of inks that are adhered and solidified in a dot shape, the ink solidified portion extends in the plane direction when viewed macroscopically. Although they form one continuous layer, it should be noted that there may be innumerable minute gaps in the plane when viewed microscopically. When viewed microscopically in this way, even if there are minute gaps, if they form one continuous layer macroscopically, they are included in the solid category.
　デザイン印刷部２の画像は、標示のみでもよく、或いは、非標示のみでもよく、或いは、標示及び非標示でもよい。好ましくは、デザイン印刷部２の画像は、標示のみから構成され、又は、標示及び非標示から構成される。１つの好ましいデザイン印刷部２は、標示を表す複数の印刷部からなり、もう１つの好ましいデザイン印刷部２は、標示を表す少なくとも１つの印刷部と、非標示を表す少なくとも１つの印刷部と、からなる。特に好ましいデザイン印刷部２は、標示を表す２つ以上の印刷部と、非標示を表す１つの印刷部と、からなる。 The image of the design printing unit 2 may be only marked or non-marked, or may be marked and non-marked. Preferably, the image of the design printing unit 2 is composed of only markings, or is composed of markings and non-marking. One preferred design printing section 2 comprises a plurality of printing sections representing markings, and another preferred design printing section 2 comprises at least one printing section representing markings, at least one printing section representing non-marking, and more. Consists of. A particularly preferable design printing unit 2 includes two or more printing units that represent markings and one printing unit that represents non-marking.
　図示例では、第１インキを凸版印刷して形成された第１インキ印刷部２１は、それ以外のインキ印刷部（第２乃至第５インキ印刷部２２乃至２５など）の背景となる背景印刷部とされている。背景印刷部（第１インキ印刷部２１）は、他のインキ印刷部の標示を際立たせる効果及び他のインキ印刷部の標示と融合して、デザイン印刷部２によって表されるデザインの１つの要素となる。背景印刷部である第１インキ印刷部２１は、他のインキ印刷部（第２乃至第５インキ印刷部２２乃至２５など）の裏面及びウェブ１の裏面（インキ印刷部が形成されていない範囲のウェブ１の裏面）を覆うように、その他のインキ印刷部の裏面及びウェブ１の裏面に延在して形成される。従って、第１インキ印刷部２１は、デザイン印刷部２の最裏面部を構成している。なお、図示例では、他のインキ印刷部（第２乃至第５インキ印刷部２２乃至２５など）は、ウェブ１と第１インキ印刷部２１の間に介在されている。 In the illustrated example, the first ink printing unit 21 formed by letterpress printing the first ink is a background printing unit that serves as a background for other ink printing units (second to fifth ink printing units 22 to 25, etc.). It is said that. The background printing unit (first ink printing unit 21) is one element of the design represented by the design printing unit 2 by fusing with the effect of making the markings of the other ink printing units stand out and the markings of the other ink printing units. It becomes. The first ink printing unit 21, which is the background printing unit, includes the back surface of other ink printing units (second to fifth ink printing units 22 to 25, etc.) and the back surface of the web 1 (range in which the ink printing unit is not formed). It is formed so as to extend over the back surface of the other ink printing portion and the back surface of the web 1 so as to cover the back surface of the web 1. Therefore, the first ink printing unit 21 constitutes the backmost surface portion of the design printing unit 2. In the illustrated example, other ink printing units (second to fifth ink printing units 22 to 25, etc.) are interposed between the web 1 and the first ink printing unit 21.
　背景印刷部である第１インキ印刷部２１は、上述のように、クリスタルカット模様、波模様、インキ付着量の差によって表されたグラデーション模様などの絵柄を表した印刷部でもよく、或いは、無模様一色の印刷部でもよい。好ましくは、第１インキ印刷部２１は、標示又は非標示のベタ状の印刷部であり、より好ましくは、非標示の無模様一色のベタ状の印刷部である。 As described above, the first ink printing unit 21, which is the background printing unit, may or may not be a printing unit that represents a pattern such as a crystal cut pattern, a wavy pattern, or a gradation pattern represented by a difference in the amount of ink adhered. A printing unit with a single color pattern may be used. Preferably, the first ink printing unit 21 is a marked or non-marked solid printing unit, and more preferably a non-marked, non-patterned, solid color printing unit.
　第１インキ印刷部２１の色彩は、特に限定されず、白色、銀色、黒色などの任意の色彩から選ばれる１色である。好ましくは、無模様一色の第１インキ印刷部２１は、白色である。このような無模様白色の第１インキ印刷部２１は、白色インキ（第１インキ）をウェブ１に凸版印刷することによって形成できる。 The color of the first ink printing unit 21 is not particularly limited, and is one color selected from arbitrary colors such as white, silver, and black. Preferably, the first ink printing unit 21 having no pattern and one color is white. Such a patternless white first ink printing unit 21 can be formed by letterpress printing white ink (first ink) on the web 1.
　第１インキ印刷部２１以外のインキ印刷部（第２乃至第５インキ印刷部２２乃至２５）は、ウェブ１の裏面に直接的に設けられ、第１インキ印刷部２１が、それらのインキ印刷部２２乃至２５を覆うように、それらのインキ印刷部２２乃至２５の裏面及びウェブ１の裏面に設けられる。各インキ印刷部（第１乃至第５インキ印刷部２１乃至２５）の厚みは、特に限定されず、それぞれ独立して、例えば、０．５μｍ～５μｍである。 The ink printing units (second to fifth ink printing units 22 to 25) other than the first ink printing unit 21 are provided directly on the back surface of the web 1, and the first ink printing unit 21 is the ink printing unit thereof. It is provided on the back surface of the ink printing portions 22 to 25 and the back surface of the web 1 so as to cover 22 to 25. The thickness of each ink printing unit (first to fifth ink printing units 21 to 25) is not particularly limited, and is independently, for example, 0.5 μm to 5 μm.
　各平面図において、第１インキ印刷部２１が設けられた範囲を横長長方形で表している。この横長長方形の範囲に、ベタ状に第１インキを凸版印刷することにより、第１インキ印刷部２１が形成されている。ただし、第１インキ印刷部２１が設けられる範囲の平面視形状、及び、その配置は、図示例に限定されるわけではなく、これらは、あくまで参考的に記載していることに留意されたい。 In each plan view, the range in which the first ink printing unit 21 is provided is represented by a horizontally long rectangle. The first ink printing portion 21 is formed by letterpress printing the first ink in a solid shape in the range of the horizontally long rectangle. However, it should be noted that the plan-view shape and the arrangement thereof in the range in which the first ink printing unit 21 is provided are not limited to the illustrated examples, and these are described for reference only.
　なお、ウェブ１の裏面側から見ると、第２乃至第５インキ印刷部２２乃至２５は、背景印刷部である第１インキ印刷部２１に覆われているので、明瞭に視認できない。図１においては、第２乃至第５インキ印刷部２２乃至２５が表面側から明瞭に視認できることを表す意味で、実線で描いたが、図２においては、第２乃至第５インキ印刷部２２乃至２５が裏面側から明瞭に視認できないことを表す意味で、これらを破線で描いている。 When viewed from the back surface side of the web 1, the second to fifth ink printing units 22 to 25 are covered with the first ink printing unit 21 which is the background printing unit, and therefore cannot be clearly seen. In FIG. 1, the second to fifth ink printing units 22 to 25 are drawn with solid lines in the sense that they can be clearly seen from the surface side, but in FIG. 2, the second to fifth ink printing units 22 to 25 are drawn. These are drawn with broken lines in the sense that 25 is not clearly visible from the back surface side.
　第２乃至第５インキ印刷部２２乃至２５は、それぞれ独立して、任意の標示を表している。標示によって視覚的に伝達される内容（情報）の観点では、大別して、法定表示、非法定表示がある。法定表示は、法律、業界団体の取り決め又は慣習などによって表すべきものをいう。法定表示は、長尺印刷物Ａを適用する商品に応じて決定され、例えば、商品名、成分、原産地、内容量、賞味期限、製造日、製造者（販売者）などが挙げられる。 The second to fifth ink printing units 22 to 25 independently represent arbitrary markings. From the viewpoint of the content (information) visually transmitted by the sign, there are roughly two types: legal display and non-legal display. Legal labeling refers to what should be represented by law, trade association agreements or customs. The statutory display is determined according to the product to which the long printed matter A is applied, and examples thereof include a product name, an ingredient, a place of origin, a content, an expiration date, a date of manufacture, and a manufacturer (seller).
　法定表示は、一般に、主として文字からなるが、これに限定されず、記号などを含んでいる場合もある。非法定表示は、通常、商品を宣伝するために任意に表すものをいう。非法定表示は、一般に、商標（商品名）、キャラクター、商品イメージ、商品説明、キャッチフレーズなどが挙げられる。 The statutory display generally consists mainly of characters, but it is not limited to this and may include symbols and the like. Non-statutory labeling usually refers to what is arbitrarily represented to promote a product. Non-statutory indications generally include trademarks (product names), characters, product images, product descriptions, catchphrases, and the like.
　例えば、デザイン印刷部２を構成する複数のインキ印刷部のうち少なくとも１つは、法定表示を表す印刷部であり、それらのうち少なくとも１つは、非法定表示を表す印刷部である。図示例では、第２インキを凸版印刷して形成された第２インキ印刷部２２は、法定表示を表し、第３乃至第５インキを凸版印刷して形成された第３乃至第５インキ印刷部は、それぞれ非法定表示を表している。 For example, at least one of the plurality of ink printing units constituting the design printing unit 2 is a printing unit representing a legal display, and at least one of them is a printing unit representing a non-statutory display. In the illustrated example, the second ink printing unit 22 formed by letterpress printing the second ink represents a legal display, and the third to fifth ink printing portions formed by letterpress printing the third to fifth inks. Represent each non-statutory display.
　各平面図において、第２インキ印刷部２２が設けられた範囲を正方形で表し、第３インキ印刷部が設けられた範囲を縦長長方形で表し、第４インキ印刷部が設けられた範囲を三角形で表し、第５インキ印刷部が設けられた範囲を円形で表している。 In each plan view, the range provided with the second ink printing section 22 is represented by a square, the range provided with the third ink printing section is represented by a vertically long rectangle, and the range provided with the fourth ink printing section is represented by a triangle. The area where the fifth ink printing unit is provided is represented by a circle.
　ただし、第２乃至第５インキ印刷部２２乃至２５が設けられる範囲の平面視形状、及び、それらの配置は、図示例に限定されるわけではなく、これらは、あくまで参考的に記載していることに留意されたい。さらに、第２乃至第５インキ印刷部２２乃至２５が、文字や記号を表している場合、前記平面視形状（例えば、第２インキ印刷部２２では正方形、第３インキ印刷部２３では縦長長方形など）の範囲内に、文字や記号が集中的に表されている。また、図示例では、第１乃至第５インキ印刷部２１乃至２５は、それぞれ１箇所の範囲に纏まって形成されているが、それぞれ、２箇所以上の範囲に分散して形成されていてもよい。 However, the plan-view shapes in the range in which the second to fifth ink printing units 22 to 25 are provided and their arrangements are not limited to the illustrated examples, and these are described for reference only. Please note that. Further, when the second to fifth ink printing units 22 to 25 represent characters or symbols, the plan view shape (for example, a square in the second ink printing unit 22, a vertically long rectangle in the third ink printing unit 23, etc.) ), Characters and symbols are intensively represented. Further, in the illustrated example, the first to fifth ink printing units 21 to 25 are each formed in a range of one place, but each may be formed dispersed in a range of two or more places. ..
　長手方向における長さの観点では、第１インキ印刷部２１の長手方向長さは、第２インキ印刷部２２の長手方向長さよりも大きい。第１インキ印刷部２１及び第２インキ印刷部２２以外のインキ印刷部の長手方向長さは、第１インキ印刷部２１の長手方向長さよりも小さいことを条件にして、特に限定されず、第２インキ印刷部２２の長手方向と同じでもよく、或いは、小さくてもよい。例えば、第１インキ印刷部２１及び第２インキ印刷部２２以外のインキ印刷部の長手方向長さは、いずれも、第２インキ印刷部２２の長手方向よりも小さい。例えば、第１インキ印刷部２１の長手方向長さ＞第２インキ印刷部２２の長手方向長さ＞第３インキ印刷部２３の長手方向長さ≧第４インキ印刷部２４の長手方向長さ≧第５インキ印刷部２５の長手方向長さ、の関係を満たしている。 From the viewpoint of the length in the longitudinal direction, the length in the longitudinal direction of the first ink printing unit 21 is larger than the length in the longitudinal direction of the second ink printing unit 22. The length of the ink printing unit other than the first ink printing unit 21 and the second ink printing unit 22 is not particularly limited, provided that it is smaller than the length of the first ink printing unit 21 in the longitudinal direction. 2 It may be the same as the longitudinal direction of the ink printing unit 22, or may be smaller. For example, the length of the ink printing unit other than the first ink printing unit 21 and the second ink printing unit 22 in the longitudinal direction is smaller than that of the second ink printing unit 22 in the longitudinal direction. For example, the longitudinal length of the first ink printing section 21> the longitudinal length of the second ink printing section 22> the longitudinal length of the third ink printing section 23 ≧ the longitudinal length of the fourth ink printing section 24 ≧ The relationship between the length of the fifth ink printing unit 25 in the longitudinal direction is satisfied.
　図示例では、第１インキ印刷部２１の長手方向長さ＞第２インキ印刷部２２の長手方向長さ＞第３インキ印刷部２３の長手方向長さ＞第４インキ印刷部２４の長手方向長さ＞第５インキ印刷部２５の長手方向長さ、の関係を満たしている。なお、第１乃至第５インキ印刷部２１乃至２５が、長手方向においてそれぞれ２箇所以上の範囲に分散して形成されている場合には、その第１乃至第５インキ印刷部２１乃至２５の各長手方向長さは、それぞれ、その２箇所以上の範囲の長手方向長さの合計をいう。 In the illustrated example, the longitudinal length of the first ink printing section 21> the longitudinal length of the second ink printing section 22> the longitudinal length of the third ink printing section 23> the longitudinal length of the fourth ink printing section 24. The relationship of> the length of the fifth ink printing unit 25 in the longitudinal direction is satisfied. When the first to fifth ink printing units 21 to 25 are dispersed in two or more locations in the longitudinal direction, each of the first to fifth ink printing units 21 to 25 is formed. The longitudinal length refers to the total of the longitudinal lengths of the two or more ranges, respectively.
　例えば、第１インキ印刷部２１の長手方向長さを１００％とした場合、第２インキ印刷部２２の長手方向長さは、３０％～９５％であり、第３インキ印刷部２３の長手方向長さは、３０％～９０％であり、第４インキ印刷部２４の長手方向長さは、１５％～６０％であり、第５インキ印刷部２５の長手方向長さは、１５％～６０％である。第１乃至第５インキ印刷部２１乃至２５の短手方向長さは、特に限定されず、全て同じでもよく、或いは、互いに異なっていてもよい。第１インキ印刷部２１を背景印刷とする場合には、通常、図示例のように、第１インキ印刷部２１の短手方向長さが最も大きい。 For example, when the longitudinal length of the first ink printing unit 21 is 100%, the longitudinal length of the second ink printing unit 22 is 30% to 95%, and the longitudinal length of the third ink printing unit 23 is 30%. The length is 30% to 90%, the longitudinal length of the fourth ink printing section 24 is 15% to 60%, and the longitudinal length of the fifth ink printing section 25 is 15% to 60%. %. The lengths of the first to fifth ink printing units 21 to 25 in the lateral direction are not particularly limited, and they may all be the same or may be different from each other. When the first ink printing unit 21 is used for background printing, the length of the first ink printing unit 21 in the lateral direction is usually the largest as shown in the illustrated example.
＜ベアラーバー印刷部＞
　ベアラーバー印刷部３は、第１インキを凸版印刷した第１バー部３１と、第２インキを凸版印刷した第２バー部３２と、を有し、第１バー部３１の幅が、第２バー部３２の幅よりも大きい。 <Bearer bar printing department>
The bearer bar printing section 3 has a first bar section 31 on which the first ink is letterpress printed and a second bar section 32 on which the second ink is letterpress printed, and the width of the first bar section 31 is the second bar. It is larger than the width of the portion 32.
　ベアラーバー印刷部３は、第１バー部３１及び第２バー部３２の２つのバー部を有していることを条件として、３つ以上のバー部を有していてもよい。好ましくは、ベアラーバー印刷部３は、デザイン印刷部２の各インキ印刷部にそれぞれ対応した、複数のバー部からなる。上述のように、デザイン印刷部２が第１乃至第５インキ印刷部２１乃至２５からなる場合、ベアラーバー印刷部３は、それぞれのインキ印刷部に対応して、第１乃至第５バー部３１乃至３５からなる。 The bearer bar printing unit 3 may have three or more bar units, provided that the bearer bar printing unit 3 has two bar units, a first bar unit 31 and a second bar unit 32. Preferably, the bearer bar printing unit 3 is composed of a plurality of bar units corresponding to each ink printing unit of the design printing unit 2. As described above, when the design printing unit 2 is composed of the first to fifth ink printing units 21 to 25, the bearer bar printing unit 3 corresponds to each ink printing unit, and the first to fifth bar units 31 to It consists of 35.
　第１乃至第５バー部３１乃至３５は、いずれも、ウェブ１の長手方向に帯状に延在する。ただし、第１乃至第５バー部３１乃至３５は、（ウェブ１の長手方向全体に亘って連続しておらず）長手方向の所々で周期的に途切れる箇所を有しつつ、長手方向に帯状に延在する。この途切れ箇所は、後述する製法のように、円筒状版の継ぎ目部分に相当する。図示例では、第１乃至第５バー部３１乃至３５の各途切れ箇所は、短手非画像部２ａに一致している。 The first to fifth bar portions 31 to 35 all extend in a strip shape in the longitudinal direction of the web 1. However, the first to fifth bar portions 31 to 35 are formed in a strip shape in the longitudinal direction while having periodically interrupted portions in the longitudinal direction (not continuous over the entire longitudinal direction of the web 1). It is postponed. This interrupted portion corresponds to the seam portion of the cylindrical plate, as in the manufacturing method described later. In the illustrated example, each of the interrupted portions of the first to fifth bar portions 31 to 35 coincides with the short non-image portion 2a.
　第１バー部３１は、第１インキを凸版印刷したものからなる。従って、第１インキ印刷部２１と第１バー部３１は、同じインキ（第１インキ）から形成されている。第２バー部３２は、第２インキを凸版印刷したものからなる。従って、第２インキ印刷部２２と第２バー部３２は、同じインキ（第２インキ）から形成されている。第３バー部３３は、第３インキを凸版印刷したものからなる。従って、第３インキ印刷部２３と第３バー部３３は、同じインキ（第３インキ）から形成されている。第４バー部３４は、第４インキを凸版印刷したものからなる。従って、第４インキ印刷部２４と第４バー部３４は、同じインキ（第４インキ）から形成されている。第５バー部３５は、第５インキを凸版印刷したものからなる。従って、第５インキ印刷部２５と第５バー部３５は、同じインキ（第５インキ）から形成されている。 The first bar portion 31 is formed by letterpress printing of the first ink. Therefore, the first ink printing unit 21 and the first bar unit 31 are formed of the same ink (first ink). The second bar portion 32 is formed by letterpress printing of the second ink. Therefore, the second ink printing section 22 and the second bar section 32 are formed of the same ink (second ink). The third bar portion 33 is formed by letterpress printing of the third ink. Therefore, the third ink printing unit 23 and the third bar unit 33 are formed of the same ink (third ink). The fourth bar portion 34 is formed by letterpress printing of the fourth ink. Therefore, the fourth ink printing section 24 and the fourth bar section 34 are formed of the same ink (fourth ink). The fifth bar portion 35 is formed by letterpress printing of the fifth ink. Therefore, the fifth ink printing section 25 and the fifth bar section 35 are formed of the same ink (fifth ink).
　各バー部（第１乃至第５バー部３１乃至３５）の厚みは、特に限定されず、それぞれ独立して、例えば、０．５μｍ～５μｍである。幅（ウェブ１の短手方向における長さ）の観点では、第１バー部３１の幅は、第２バー部３２の幅よりも大きい。 The thickness of each bar portion (first to fifth bar portions 31 to 35) is not particularly limited, and is independently, for example, 0.5 μm to 5 μm. From the viewpoint of the width (the length of the web 1 in the lateral direction), the width of the first bar portion 31 is larger than the width of the second bar portion 32.
　第１バー部３１及び第２バー部３２以外のバー部の幅は、第１バー部３１の幅よりも小さいことを条件にして、特に限定されず、第２バー部３２の幅と同じでもよく、或いは、その幅よりも小さくてもよい。例えば、第１バー部３１及び第２バー部３２以外のバー部の幅は、いずれも、第２バー部３２の幅よりも小さい。例えば、第１バー部３１の幅＞第２バー部３２の幅＞第３バー部３３の幅≧第４バー部３４の幅≧第５バー部３５の幅、の関係を満たしている。 The width of the bar portions other than the first bar portion 31 and the second bar portion 32 is not particularly limited, provided that it is smaller than the width of the first bar portion 31, and may be the same as the width of the second bar portion 32. It may be good or smaller than its width. For example, the width of the bar portions other than the first bar portion 31 and the second bar portion 32 is smaller than the width of the second bar portion 32. For example, the relationship of the width of the first bar portion 31> the width of the second bar portion 32> the width of the third bar portion 33 ≥ the width of the fourth bar portion 34 ≥ the width of the fifth bar portion 35 is satisfied.
　図示例では、第１バー部３１の幅３１Ｗ＞第２バー部３２の幅３２Ｗ＞第３バー部３３の幅３３Ｗ＞第４バー部３４の幅３４Ｗ＞第５バー部３５の幅３５Ｗ、の関係を満たしている（符号３１Ｗ乃至３５Ｗは、図３を参照）。なお、第１乃至第５バー部３１乃至３５が、短手方向においてそれぞれ２箇所以上の範囲に分散して形成されている場合には、その第１乃至第５バー部３１乃至３５の各幅は、それぞれ、その２箇所以上の範囲の幅の合計をいう。 In the illustrated example, the width 31 W of the first bar portion 31> the width 32 W of the second bar portion 32> the width 33 W of the third bar portion 33> the width 34 W of the fourth bar portion 34> the width 35 W of the fifth bar portion 35. The relationship is satisfied (see FIG. 3 for reference numerals 31W to 35W). When the first to fifth bar portions 31 to 35 are dispersedly formed in two or more locations in the lateral direction, the widths of the first to fifth bar portions 31 to 35 are each. Means the sum of the widths of the two or more ranges, respectively.
　例えば、第１バー部３１の幅を１００％とした場合、第２バー部３２の幅は、３１％～６０％であり、第３バー部３３の幅は、１１％～３０％であり、第４バー部３４の幅は、１％～１０％であり、第５バー部３５の幅は、０％を越え１０％以下である。 For example, assuming that the width of the first bar portion 31 is 100%, the width of the second bar portion 32 is 31% to 60%, and the width of the third bar portion 33 is 11% to 30%. The width of the fourth bar portion 34 is 1% to 10%, and the width of the fifth bar portion 35 is more than 0% and 10% or less.
　第１乃至第５インキ印刷部２１乃至２５の長手方向長さと、それらに対応する第１乃至第５バー部３１乃至３５の幅は、相関関係にある。つまり、長手方向長さが大きいインキ印刷部に対応するバー部は、その幅が大きい。例えば、長手方向長さが最も大きい第１インキ印刷部２１に対応する第１バー部３１は、その幅が最も大きく、長手方向長さが第１インキ印刷部２１よりも小さい第２インキ印刷部２２に対応する第２バー部３２は、その幅が第１バー部３１よりも小さい。 There is a correlation between the longitudinal lengths of the first to fifth ink printing portions 21 to 25 and the corresponding widths of the first to fifth bar portions 31 to 35. That is, the bar portion corresponding to the ink printing portion having a large length in the longitudinal direction has a large width. For example, the first bar section 31 corresponding to the first ink printing section 21 having the largest longitudinal length has the largest width and the second ink printing section having a longer longitudinal length than the first ink printing section 21. The width of the second bar portion 32 corresponding to 22 is smaller than that of the first bar portion 31.
　ウェブ１の短手方向におけるベアラーバー印刷部３（第１乃至第５バー部３１乃至３５）の配置は、特に限定されない。ベアラーバー印刷部３（第１乃至第５バー部３１乃至３５）は、例えば、ウェブ１の短手方向右端部又は左端部に配置されていてもよく、ウェブ１の短手方向中間部に配置されていてもよい。 The arrangement of the bearer bar printing portions 3 (first to fifth bar portions 31 to 35) in the lateral direction of the web 1 is not particularly limited. The bearer bar printing portions 3 (first to fifth bar portions 31 to 35) may be arranged, for example, at the right end portion or the left end portion in the lateral direction of the web 1, and may be arranged at the intermediate portion in the lateral direction of the web 1. You may be.
　ベアラーバー印刷部３がウェブ１の短手方向右端部に配置されている場合とは、ウェブ１の短手方向右縁と最も右側のデザイン列との間の領域に、ベアラーバー印刷部３が配置されることをいう。ベアラーバー印刷部３がウェブ１の短手方向左端部に配置されている場合とは、ウェブ１の短手方向左縁と最も左側のデザイン列との間の領域に、ベアラーバー印刷部３が配置されることをいう。ベアラーバー印刷部３がウェブ１の短手方向中間部に配置されている場合とは、短手方向において隣接する２つのデザイン列の間の領域に、ベアラーバー印刷部３が配置されることをいう。 When the bearer bar printing unit 3 is arranged at the right end of the web 1 in the lateral direction, the bearer bar printing unit 3 is arranged in the area between the right edge of the web 1 in the lateral direction and the rightmost design row. To say that. When the bearer bar printing unit 3 is arranged at the left end of the web 1 in the lateral direction, the bearer bar printing unit 3 is arranged in the area between the left edge of the web 1 in the lateral direction and the leftmost design row. To say that. The case where the bearer bar printing unit 3 is arranged in the intermediate portion in the lateral direction of the web 1 means that the bearer bar printing unit 3 is arranged in the area between two adjacent design rows in the lateral direction.
　好ましくは、ベアラーバー印刷部３（第１乃至第５バー部３１乃至３５）は、ウェブ１の短手方向中間部に配置される。図示例では、ベアラーバー印刷部３は、ウェブ１の短手方向略中央部（例えば、右側の２つのデザイン列と左側の２つのデザイン列の間の領域）に配置されている。 Preferably, the bearer bar printing unit 3 (first to fifth bar units 31 to 35) is arranged in the intermediate portion in the lateral direction of the web 1. In the illustrated example, the bearer bar printing unit 3 is arranged at a substantially central portion in the lateral direction of the web 1 (for example, an area between two design rows on the right side and two design rows on the left side).
　第１乃至第５バー部３１乃至３５（各バー部）について、少なくとも１つのバー部と少なくとも１つのバー部が重なった状態でウェブ１に設けられていてもよく、或いは、少なくとも１つのバー部と少なくとも１つのバー部が重なり且つ少なくとも１つのバー部が他のバー部に重なることなくウェブ１に直接的に設けられていてもよく、或いは、第１乃至第５バー部３１乃至３５（各バー部）が、重なることなくそれぞれ独立してウェブ１に直接的に設けられていてもよい。 The first to fifth bar portions 31 to 35 (each bar portion) may be provided on the web 1 in a state where at least one bar portion and at least one bar portion overlap each other, or at least one bar portion. And at least one bar portion may be provided directly on the web 1 without overlapping the other bar portions, or the first to fifth bar portions 31 to 35 (each). The bar portions) may be provided directly on the web 1 independently of each other without overlapping.
　少なくとも１つのバー部と少なくとも１つのバー部が重なった状態でウェブ１に設けられている場合としては、例えば、第２乃至第５バー部３２乃至３５（複数のバー部）が重なることなく短手方向に並んで配置され且つ第１バー部３１がその第２乃至第５バー部３２乃至３５の全てに重なって配置されている場合、或いは、第２乃至第４バー部３２乃至３４（複数のバー部）が重なることなく短手方向に並んで配置され且つ第１バー部３１及び第５バー部３５がその第２乃至第４バー部３２乃至３４の全てに重なって配置されている場合、或いは、全てのバー部３１乃至３５が厚み方向に重なっている場合、などが挙げられる。 When the web 1 is provided with at least one bar portion and at least one bar portion overlapping, for example, the second to fifth bar portions 32 to 35 (plurality of bar portions) are short without overlapping. When the first bar portions 31 are arranged side by side in the hand direction and the first bar portions 31 are arranged so as to overlap all of the second to fifth bar portions 32 to 35, or the second to fourth bar portions 32 to 34 (plural). Bar portions) are arranged side by side in the lateral direction without overlapping, and the first bar portion 31 and the fifth bar portion 35 are arranged so as to overlap all of the second to fourth bar portions 32 to 34. Alternatively, when all the bar portions 31 to 35 overlap in the thickness direction, and the like can be mentioned.
　後述するように、長尺印刷物Ａのうちベアラーバー印刷部３を含む領域は、長尺印刷物の使用時に廃棄されるため、廃棄量を少なくする観点から、ベアラーバー印刷部３の幅は、できるだけ小さいことが好ましい。かかる観点から、ベアラーバー印刷部３を構成する第１乃至第５バー部３１乃至３５（各バー部）は、少なくとも１つのバー部と少なくとも１つのバー部が重なっていることが好ましく、３つ以上のバー部が重なっていることがより好ましく、全てのバー部が厚み方向に重なっていることが最も好ましい。 As will be described later, the area of the long printed matter A including the bearer bar printing section 3 is discarded when the long printed matter is used. Therefore, from the viewpoint of reducing the amount of waste, the width of the bearer bar printing section 3 should be as small as possible. Is preferable. From this point of view, it is preferable that at least one bar portion and at least one bar portion overlap with each other in the first to fifth bar portions 31 to 35 (each bar portion) constituting the bearer bar printing portion 3. It is more preferable that the bar portions of the above are overlapped, and it is most preferable that all the bar portions are overlapped in the thickness direction.
　他方、後述するように、長尺印刷物Ａはロール状に巻いて保管・運搬されるが、そのロール体において長尺印刷物Ａのブロッキングを防止する観点から、ベアラーバー印刷部３を構成する第１乃至第５バー部３１乃至３５（各バー部）は、互いに重なることなく短手方向に並んで配置されていることが好ましい。各バー部が重なっていると、その重なり部分におけるベアラーバー印刷部３の厚みが大きくなり、長尺印刷物Ａをロール状に巻いた際に、前記重なり部分においてブロッキングを生じ易くなるからである。ブロッキング抑制の観点から、ベアラーバー印刷部３の最大厚みは、デザイン印刷部２の最大厚みと同じ又はそれよりも小さいことが好ましい。 On the other hand, as will be described later, the long printed matter A is rolled into a roll and stored / transported. From the viewpoint of preventing the long printed matter A from being blocked in the roll body, the first to the bearer bar printing units 3 are formed. It is preferable that the fifth bar portions 31 to 35 (each bar portion) are arranged side by side in the lateral direction without overlapping each other. This is because when the bar portions overlap, the thickness of the bearer bar printing portion 3 at the overlapping portion increases, and when the long printed matter A is wound in a roll shape, blocking is likely to occur at the overlapping portion. From the viewpoint of suppressing blocking, the maximum thickness of the bearer bar printing unit 3 is preferably the same as or smaller than the maximum thickness of the design printing unit 2.
　なお、複数のバー部からなるベアラーバー印刷部３の幅をできるだけ小さくするために、短手方向に並んで配置される複数のバー部は、短手方向両側縁が近接して又は短手方向両側縁が接するように設けられていることが好ましい。 In order to make the width of the bearer bar printing portion 3 composed of the plurality of bar portions as small as possible, the plurality of bar portions arranged side by side in the lateral direction have both edges in the lateral direction close to each other or both sides in the lateral direction. It is preferable that the edges are provided so as to be in contact with each other.
　廃棄量の低減及びブロッキング防止を両立させるために、ベアラーバー印刷部３は、２つのバー部が重なっていることが好ましい。２つのバー部が重なっていても、ベアラーバー印刷部の厚みは、さほど大きくならず、長尺印刷物のブロッキングを抑制できる。例えば、ベアラーバー印刷部３が第１及び第２バー部３１，３２からなる場合、第１及び第２バー部３１，３２は重なって設けられることが好ましい。例えば、ベアラーバー印刷部３が第１及び第２バー部３１，３２以外のバー部を有する場合、第１バー部３１以外のバー部は、互いに重なることなく短手方向に並んで配置され、その並んで配置された複数のバー部のそれぞれに重なるように第１バー部３１が配置されることが好ましい。 In order to reduce the amount of waste and prevent blocking, it is preferable that the bearer bar printing section 3 has two bar sections that overlap each other. Even if the two bar portions overlap, the thickness of the bearer bar printed portion is not so large, and blocking of long printed matter can be suppressed. For example, when the bearer bar printing section 3 is composed of the first and second bar sections 31, 32, it is preferable that the first and second bar sections 31, 32 are provided so as to overlap each other. For example, when the bearer bar printing section 3 has bar sections other than the first and second bar sections 31, 32, the bar sections other than the first bar section 31 are arranged side by side in the lateral direction without overlapping each other. It is preferable that the first bar portion 31 is arranged so as to overlap each of the plurality of bar portions arranged side by side.
　なお、特に図示しないが、ベアラーバー印刷部３が第１乃至第５バー部３１乃至３５を有する場合、第２乃至第５バー部３２乃至３５から選ばれる３つのバー部は、互いに重なることなく短手方向に並んで配置され、残る１つのバー部が前記３つのバー部のいずれかに重なって設けられ、その並んで配置された複数のバー部のそれぞれに重なるように第１バー部３１が配置されていてもよい。例えば、第２バー部３２、第３バー部３３及び第４バー部３４が互いに重なることなく短手方向に並んで配置され、第４バー部３４が第３バー部３３に重なって設けられ、それらに重なるように第１バー部３１が設けられていてもよい。 Although not particularly shown, when the bearer bar printing section 3 has the first to fifth bar sections 31 to 35, the three bar sections selected from the second to fifth bar sections 32 to 35 are short without overlapping each other. The first bar portion 31 is arranged side by side in the hand direction, the remaining one bar portion is provided so as to overlap one of the three bar portions, and the first bar portion 31 overlaps each of the plurality of bar portions arranged side by side. It may be arranged. For example, the second bar portion 32, the third bar portion 33, and the fourth bar portion 34 are arranged side by side in the lateral direction without overlapping each other, and the fourth bar portion 34 is provided so as to overlap the third bar portion 33. The first bar portion 31 may be provided so as to overlap them.
　或いは、特に図示しないが、ベアラーバー印刷部３が第１乃至第５バー部３１乃至３５を有する場合、第２乃至第５バー部３２乃至３５から選ばれる２つのバー部は、互いに重なることなく短手方向に並んで配置され、残る２つのバー部がそれぞれ短手方向に並んだ２つのバー部にそれぞれ重なって設けられ、その並んで配置された複数のバー部のそれぞれに重なるように第１バー部３１が配置されていてもよい。例えば、第２バー部３２及び第３バー部３３が互いに重なることなく短手方向に並んで配置され、第４バー部３４が第２バー部３２に重なり且つ第５バー部３５が第３バー部３３に重なって設けられ、それらに重なるように第１バー部３１が設けられていてもよい。 Alternatively, although not particularly shown, when the bearer bar printing section 3 has the first to fifth bar sections 31 to 35, the two bar sections selected from the second to fifth bar sections 32 to 35 are short without overlapping each other. The first bar portions are arranged side by side in the hand direction, and the remaining two bar portions are provided so as to overlap each of the two bar portions arranged in the lateral direction, respectively, and overlap with each of the plurality of bar portions arranged side by side. The bar portion 31 may be arranged. For example, the second bar portion 32 and the third bar portion 33 are arranged side by side in the lateral direction without overlapping each other, the fourth bar portion 34 overlaps the second bar portion 32, and the fifth bar portion 35 is the third bar. The first bar portion 31 may be provided so as to overlap the portions 33 and overlap the portions 33.
　図示例のように、ベアラーバー印刷部３が第１乃至第５バー部３１乃至３５からなる場合、第２乃至第５バー部３２乃至３５は、互いに重なることなく短手方向に並んで配置され、その第２乃至第５バー部３２乃至３５のそれぞれに重なるように第１バー部３１が配置されることが好ましい。この場合、図示例のように、第２乃至第５バー部３２乃至３５がウェブ１の裏面に直接的に設けられ、第１バー部３１が、第２乃至第５バー部３２乃至３５の裏面を覆うように設けられる。なお、特に図示しないが、第１バー部３１がウェブ１の裏面に直接的に設けられ、第２乃至第５バー部３２乃至３５が、互いに重なることなく第１バー部３１の裏面に並んで設けられていてもよい。図示例では、短手方向に並んで配置されている第２乃至第５バー部３２乃至３５は、隣接する短手方向両側縁が近接して設けられているが、短手方向両側縁が接するように設けられていてもよい（図示せず）。 As shown in the illustrated example, when the bearer bar printing section 3 is composed of the first to fifth bar sections 31 to 35, the second to fifth bar sections 32 to 35 are arranged side by side in the lateral direction without overlapping each other. It is preferable that the first bar portion 31 is arranged so as to overlap each of the second to fifth bar portions 32 to 35. In this case, as shown in the illustrated example, the second to fifth bar portions 32 to 35 are directly provided on the back surface of the web 1, and the first bar portion 31 is the back surface of the second to fifth bar portions 32 to 35. It is provided so as to cover. Although not particularly shown, the first bar portion 31 is provided directly on the back surface of the web 1, and the second to fifth bar portions 32 to 35 are lined up on the back surface of the first bar portion 31 without overlapping each other. It may be provided. In the illustrated example, the second to fifth bar portions 32 to 35 arranged side by side in the lateral direction are provided with adjacent both edges in the lateral direction close to each other, but both edges in the lateral direction are in contact with each other. (Not shown).
　ベアラーバー印刷部３を構成する各バー部（第１乃至第５バー部３１乃至３５）の単位面積あたりのインキ付着量は、特に限定されず、適宜設定できる。上述のように、ベアラーバー印刷部３の厚みを小さくすると、ブロッキングの発生を抑制できる。例えば、第１バー部３１と第２バー部３２が重なっている場合、第１バー部３１と第２バー部３２の合計厚みを比較的小さくすることにより、ブロッキングの発生を抑制できる。このため、第１バー部３１と第２バー部３２の合計厚みを比較的小さくするために、第２バー部３２の単位面積あたりのインキ付着量を、第１バー部３１の単位面積あたりのインキ付着量よりも小さくすることが好ましい。凸版印刷で形成されるバー部の、単位面積あたりのインキ付着量と厚みとは、通常、比例関係にあり、単位面積あたりのインキ付着量が第１バー部３１の単位面積あたりのインキ付着量よりも小さい第２バー部３２の厚みは、第１バー部３１の厚みよりも小さくなる。 The amount of ink adhered per unit area of each bar portion (first to fifth bar portions 31 to 35) constituting the bearer bar printing portion 3 is not particularly limited and can be set as appropriate. As described above, if the thickness of the bearer bar printing portion 3 is reduced, the occurrence of blocking can be suppressed. For example, when the first bar portion 31 and the second bar portion 32 overlap, the occurrence of blocking can be suppressed by making the total thickness of the first bar portion 31 and the second bar portion 32 relatively small. Therefore, in order to make the total thickness of the first bar portion 31 and the second bar portion 32 relatively small, the amount of ink adhered per unit area of the second bar portion 32 is set to the unit area of the first bar portion 31. It is preferable that the amount is smaller than the amount of ink adhered. The ink adhesion amount per unit area and the thickness of the bar portion formed by letterpress printing are usually in a proportional relationship, and the ink adhesion amount per unit area is the ink adhesion amount per unit area of the first bar portion 31. The thickness of the second bar portion 32, which is smaller than the thickness of the second bar portion 32, is smaller than the thickness of the first bar portion 31.
　同様な理由から、第２乃至第５バー部３２乃至３５のそれぞれの単位面積あたりのインキ付着量は、第１バー部３１の単位面積あたりのインキ付着量よりも小さいことが好ましい。第２乃至第５バー部３２乃至３５のそれぞれの単位面積あたりのインキ付着量は、同じでもよく、或いは、異なっていてもよい。好ましくは、第１バー部３１の単位面積あたりのインキ付着量＞第２バー部３２の単位面積あたりのインキ付着量の関係を満たし、より好ましくは、第１バー部３１の単位面積あたりのインキ付着量＞第２バー部３２の単位面積あたりのインキ付着量又は第３バー部３３の単位面積あたりのインキ付着量又は第４バー部３４の単位面積あたりのインキ付着量又は第５バー部３５の単位面積あたりのインキ付着量の関係を満たす。 For the same reason, it is preferable that the amount of ink adhered per unit area of the second to fifth bar portions 32 to 35 is smaller than the amount of ink adhered per unit area of the first bar portion 31. The amount of ink adhered to each of the second to fifth bar portions 32 to 35 per unit area may be the same or different. Preferably, the relationship of the amount of ink adhered per unit area of the first bar portion 31> the amount of ink adhered per unit area of the second bar portion 32 is satisfied, and more preferably, the ink adhered per unit area of the first bar portion 31. Adhesion amount> Ink adhesion amount per unit area of the second bar portion 32, ink adhesion amount per unit area of the third bar portion 33, ink adhesion amount per unit area of the fourth bar portion 34, or fifth bar portion 35 Satisfy the relationship of the amount of ink adhered per unit area of.

　図９（ａ）及び（ｂ）は、凸版の一部分を切断した断面を含む斜視図である。図９（ａ）および（ｂ）に示すように、第１乃至第５印刷版７１乃至７５の各凸版（デザイン凸版及びベアラー凸版）の表面には、無数の小突起７９が突設されている。従って、凸版は、微視的には、無数の小突起７９の集合で構成されている。印刷時には、各小突起７９の頂面にインキが付着しており、この各小突起７９の頂面からウェブ１にインキが移転することにより、デザイン印刷部２及びベアラーバー印刷部３が凸版印刷される。 9 (a) and 9 (b) are perspective views including a cross section obtained by cutting a part of the letterpress. As shown in FIGS. 9A and 9B, innumerable small protrusions 79 are projected on the surface of each letterpress (design letterpress and bearer letterpress) of the first to fifth printing plates 71 to 75. .. Therefore, the letterpress is microscopically composed of a set of innumerable small protrusions 79. At the time of printing, ink adheres to the top surface of each small protrusion 79, and the ink is transferred from the top surface of each small protrusion 79 to the web 1, so that the design printing section 2 and the bearer bar printing section 3 are letterpress printed.

The letterpress 79 in which the small protrusions 79 of FIG. 9A are roughly formed can print an ink printing portion and a bar portion in which the amount of ink adhered per unit area is small. The letterpress 79 in which the small protrusions 79 of FIG. 9B are densely formed can print an ink printing portion and a bar portion having a large amount of ink adhered per unit area.
　上述のように、例えば、第１バー部３１の単位面積あたりのインキ付着量＞第２バー部３２の単位面積あたりのインキ付着量の関係を満たす第１バー部３１及び第２バー部３２を形成する場合、小突起７９が密に形成されているベアラー凸版７１２を有する第１印刷版７１を用い且つ小突起７９が粗に形成されているベアラー凸版７２２を有する第２印刷版７２を用いて凸版印刷すればよい。また、第２乃至第５バー部３２乃至３５から選ばれる２つのバー部を重なって設ける場合、ブロッキング抑制の観点から、その重ね合わせる２つのバー部は、小突起７９が粗に形成されているベアラー凸版を有する印刷版を用いて形成することが好ましい。 As described above, for example, the first bar portion 31 and the second bar portion 32 satisfying the relationship of the ink adhesion amount per unit area of the first bar portion 31> the ink adhesion amount per unit area of the second bar portion 32. When forming, the first printing plate 71 having the bearer letterpress 712 in which the small protrusions 79 are densely formed is used, and the second printing plate 72 having the bearer letterpress 722 in which the small protrusions 79 are roughly formed is used. Toppan printing may be performed. Further, when two bar portions selected from the second to fifth bar portions 32 to 35 are provided so as to overlap each other, small protrusions 79 are roughly formed on the two overlapping bar portions from the viewpoint of suppressing blocking. It is preferably formed using a printing plate having a bearer letterpress.

＜＜印刷工程＞＞
　印刷工程においては、ウェブ１に少なくとも２つのインキ（第１インキ及び第２インキ）を印刷してデザイン印刷部２及びベアラーバー印刷部３を形成する。以下、上記のように第１乃至第５インキを凸版印刷することにより、第１乃至第５インキ印刷部２１乃至２５からなるデザイン印刷部２及び第１乃至第５バー部３１乃至３５からなるベアラーバー印刷部３を形成する場合を説明する。ただし、第１インキ乃至第５インキの印刷順序は、下記に限定されるわけではなく、各円筒状版の配置を適宜変更して、各インキの印刷順序を変更してもよい。 << Printing process >>
In the printing process, at least two inks (first ink and second ink) are printed on the web 1 to form the design printing section 2 and the bearer bar printing section 3.

However, the printing order of the first ink to the fifth ink is not limited to the following, and the printing order of each ink may be changed by appropriately changing the arrangement of each cylindrical plate.

Next, the fourth ink is printed on the back surface of the web 1 by the fourth cylindrical plate 64 to form the fourth ink printing portion 24 and the fourth bar portion 34, and the third cylindrical plate 63 is used to print the fourth ink on the web 1. The third ink is printed on the back surface to form the third ink printing portion 23 and the third bar portion 33.
　図６及び図１１を参照して、第２円筒状版６２により、ウェブ１の裏面に第２インキを印刷し、第２インキ印刷部２２及び第２バー部３２を形成し、最後に、第１円筒状版６１により、ウェブ１の裏面に第１インキを印刷し、第１インキ印刷部２１及び第１バー部３１を形成する。なお、インキの種類に応じて、インキの乾燥或いは紫外線などの電離線照射などを行い、各インキを硬化させる。得られた長尺印刷物Ａは、通常、芯材５９を有する巻き取り部に巻き取られる。図１２は、長尺印刷物Ａが芯材５９の周囲にロール状に巻き取られたロール体Ｂを示す。 With reference to FIGS. 6 and 11, the second ink is printed on the back surface of the web 1 by the second cylindrical plate 62 to form the second ink printing section 22 and the second bar section 32, and finally, the second ink printing section 22 and the second bar section 32 are formed. The first ink is printed on the back surface of the web 1 by the cylindrical plate 61 to form the first ink printing portion 21 and the first bar portion 31. Depending on the type of ink, the ink is dried or irradiated with ionizing rays such as ultraviolet rays to cure each ink. The obtained long printed matter A is usually wound around a winding portion having a core material 59. FIG. 12 shows a roll body B in which a long printed matter A is wound around a core material 59 in a roll shape.
＜長尺印刷物の効果＞
　本開示の長尺印刷物Ａは、デザイン印刷部２を構成するインキ印刷部の画像が凸版印刷によって綺麗に表されている。具体的には、長尺印刷物Ａを製造する際には、上述のように、円筒状版を使用してインキをウェブ１に凸版印刷する。円筒状版のバウンシングを抑制するために、印刷版にベアラー凸版が形成されている。つまり、版胴の周囲の略全体にベアラー凸版が設けられている円筒状版を用いると、円筒状版の回転中、ベアラー凸版がウェブに離れずに接触しているので、円筒状版のバウンシングを抑制できる。 <Effect of long printed matter>
In the long printed matter A of the present disclosure, the image of the ink printing unit constituting the design printing unit 2 is clearly represented by letterpress printing. Specifically, when producing the long printed matter A, as described above, the ink is letterpress-printed on the web 1 using the cylindrical plate. A bearer letterpress is formed on the printing plate in order to suppress bouncing of the cylindrical plate. In other words, if a cylindrical plate in which a bearer letterpress is provided almost entirely around the plate cylinder is used, the bearer letterpress is in contact with the web while the cylindrical plate is rotating, so that the cylindrical plate bounces. Can be suppressed.
　しかしながら、比較的長時間、連続的に印刷工程を行なっていると（印刷機を比較的長時間稼働させていると）、円筒状版が僅かにバウンシングするおそれがある。バウンシングは、凸版がウェブに接触した後に円筒状版に微小な振動が生じることによって発生すると考えられる。長手方向長さの大きいインキ印刷部を形成する円筒状版は、周方向長さの大きいデザイン凸版を有するが、前記凸版がウェブに接触した後に生じるバウンシングによって、インキ抜けが生じ易い。特に、長手方向長さが比較的大きく且つベタ状の一色のインキ印刷部（例えば、上述の第１インキ印刷部２１）を凸版印刷した場合には、バウンシングによるインキ抜けが目立ってしまう。 However, if the printing process is continuously performed for a relatively long time (when the printing machine is operated for a relatively long time), the cylindrical plate may slightly bounce. Bouncing is thought to be caused by the small vibrations in the cylindrical plate after the letterpress comes into contact with the web. The cylindrical plate forming the ink printing portion having a large length in the longitudinal direction has a design letterpress having a large length in the circumferential direction, but ink loss is likely to occur due to bouncing that occurs after the letterpress comes into contact with the web. In particular, when letterpress printing is performed on a solid color ink printing section (for example, the first ink printing section 21 described above) having a relatively large length in the longitudinal direction, ink loss due to bouncing becomes conspicuous.
　この点、本開示においては、第１バー部３１を印刷する第１印刷版７１のベアラー凸版７１２の軸方向長さが、他の印刷版（第２印刷版７２を含む）のベアラー凸版７２２の軸方向長さよりも大きい。軸方向長さが比較的大きいベアラー凸版はウェブ１に対する接触面積が大きいので、かかるベアラー凸版７１２を有する第１円筒状版６１は、バウンシングし難くなる。バウンシングし難い第１円筒状版６１を用いて凸版印刷された第１インキ印刷部２１は、インキ抜けが生じ難く、特に、一色の第１インキ印刷部２１は、綺麗に表される。 In this regard, in the present disclosure, the axial length of the bearer letterpress 712 of the first printing plate 71 that prints the first bar portion 31 is the bearer letterpress 722 of another printing plate (including the second printing plate 72). Greater than axial length. Since the bearer letterpress with a relatively large axial length has a large contact area with the web 1, the first cylindrical plate 61 having such a bearer letterpress 712 becomes difficult to bounce. The first ink printing unit 21 that is letterpress-printed using the first cylindrical plate 61 that is difficult to bounce is less likely to cause ink loss, and in particular, the one-color first ink printing unit 21 is beautifully represented.
　なお、第２乃至５印刷版の各ベアラー凸版７２２乃至７５２の周方向長さは、それぞれ第２乃至第５バー部３２乃至３５の長手方向長さに対応して順に小さいので、第２乃至第５印刷版７２乃至７５は、バウンシング抑制効果が順に低くなる。しかし、第２乃至第５印刷版７２乃至７５によって凸版印刷される第２乃至第５インキ印刷部２２乃至２５は、各長手方向長さが順に小さく、仮にバウンシングを生じても各インキ印刷部に表される画像のインキ抜けが目立ち難い。このため、長尺印刷物Ａは、デザイン印刷部２を構成するインキ印刷部が凸版印刷によって外見上綺麗に表されている。さらに、本開示の好ましい長尺印刷物によれば、ロールに巻き取った際にブロッキングを生じ難いという効果も奏する。 Since the circumferential lengths of the bearer letterpress plates 722 to 752 of the 2nd to 5th printing plates are smaller in order corresponding to the longitudinal lengths of the 2nd to 5th bar portions 32 to 35, respectively, the 2nd to 5th printing plates are used. In the 5 printing plates 72 to 75, the bouncing suppressing effect becomes lower in order. However, the second to fifth ink printing units 22 to 25, which are letterpress-printed by the second to fifth printing plates 72 to 75, have smaller lengths in the longitudinal direction in order, and even if bouncing occurs, they are printed on the ink printing units. Ink loss in the represented image is inconspicuous. For this reason, in the long printed matter A, the ink printing unit constituting the design printing unit 2 is beautifully represented by letterpress printing. Further, according to the preferred long printed matter of the present disclosure, there is also an effect that blocking is unlikely to occur when the printed matter is wound on a roll.
＜長尺印刷物の使用例＞
　長尺印刷物Ａは、デザイン印刷部２によって表された画像（デザイン）が長手方向に繰り返して配置されている。かかる長尺印刷物Ａは、各種のラベル、包装材、ラッピングリボンなどとして使用できる。ラベルとしては、筒状ラベル、巻き付けラベル、グルーラベル、インモールドラベルなどの従来公知のものが挙げられる、包装材としては、オーバーラップフィルム、ピロー包装袋用のフィルム、パウチ袋用のフィルムなどが挙げられる。 <Example of using long printed matter>
In the long printed matter A, the image (design) represented by the design printing unit 2 is repeatedly arranged in the longitudinal direction. Such a long printed matter A can be used as various labels, packaging materials, wrapping ribbons, and the like. Examples of the label include conventionally known ones such as a tubular label, a wrapping label, a glue label, and an in-mold label. Examples of the packaging material include an overlap film, a film for a pillow packaging bag, a film for a pouch bag, and the like. Can be mentioned.
　例えば、長尺印刷物Ａを筒状ラベルに加工する場合には、まず、長尺印刷物Ａを、単列のデザイン列からなる長尺シートに分割する。具体的には、図２の太矢印で示すデザイン列の境界（例えば、長手非画像部２ｂ）で、長尺印刷物Ａを長手方向と平行に切断して、１列のデザイン列を含む長尺シートを得る。図２に示すように、短手方向に４列のデザイン列が設けられた長尺印刷物Ａの場合には、４つの長尺シートが得られる。なお、長尺印刷物Ａの短手方向右側部及び左側部（いわゆる耳部）、並びに、ベアラーバー印刷部３を含む領域は、廃棄される。 For example, when processing a long printed matter A into a tubular label, first, the long printed matter A is divided into a long sheet consisting of a single row of design rows. Specifically, at the boundary of the design row indicated by the thick arrow in FIG. 2 (for example, the longitudinal non-image portion 2b), the long printed matter A is cut in parallel with the longitudinal direction, and the long printed matter A includes one row of design rows. Get a sheet. As shown in FIG. 2, in the case of the long printed matter A in which four rows of design rows are provided in the lateral direction, four long sheets can be obtained. The area including the right side portion and the left side portion (so-called ear portion) in the lateral direction of the long printed matter A and the bearer bar printing portion 3 is discarded.
　図１３は、長尺印刷物Ａを分割して得られた１つの長尺シートＣを示す。図１４は、長尺シートから筒状ラベルを形成する過程を示す参考斜視図である。図１４に示すように、前記長尺シートＣの裏面側を内側にして筒状に丸め、その短手方向左側端部Ｃ１と右側端部Ｃ２を重ね合わせて接着することにより、長尺状の筒状ラベル連続体Ｄが得られる。この長尺状の筒状ラベル連続体Ｄを、１つのデザイン毎に分割するべく長手非画像部２ｂにおいて短手方向に平行に切断することにより、１つの筒状ラベルが得られる。筒状ラベルは、熱収縮性及び／又は自己伸縮性を有するウェブ１を使用した長尺印刷物Ａの１つの使用例である。 FIG. 13 shows one long sheet C obtained by dividing the long printed matter A. FIG. 14 is a reference perspective view showing a process of forming a tubular label from a long sheet. As shown in FIG. 14, the long sheet C is rolled into a tubular shape with the back surface side inside, and the left end portion C1 and the right end portion C2 in the lateral direction are overlapped and adhered to form a long sheet. A tubular label continuum D is obtained. One tubular label can be obtained by cutting the long tubular label continuum D in parallel in the lateral direction at the longitudinal non-image portion 2b so as to divide each design. The tubular label is an example of use of a long printed matter A using a web 1 having heat shrinkage and / or self-stretchability.
　また、図１３に示す長尺シートＣを、１つのデザイン毎に分割するべく長手非画像部２ｂにおいて短手方向に平行に切断することにより、枚葉状のラベルが得られる。この枚葉状のラベルは、巻き付けラベル、グルーラベル、インモールドラベルなどとして使用できる。
　枚葉状のラベルＥは、例えば、図１５に示すように、容器などの被着体９に巻き付けるようにして装着される。このような装着方法によるラベルＥは、巻き付けラベルとも呼ばれる。この巻き付けラベルＥの少なくとも一方の端部Ｅ１の裏面に接着剤を塗布し、図１５（ａ）に示すように、その一方の端部Ｅ１を容器などの被着体９に貼り付け、巻き付けラベルＥを被着体９の周囲に巻き付けた後、図１５（ｂ）に示すように、その他方の端部Ｅ２の裏面を一方の端部Ｅ１の表面に貼り付ける（又はその他方の端部Ｅ２の裏面を被着体９に貼り付ける）ことにより、ラベル付き物品Ｆが得られる。 Further, a single-wafer-shaped label can be obtained by cutting the long sheet C shown in FIG. 13 in parallel in the lateral direction at the longitudinal non-image portion 2b so as to divide each design. This sheet-fed label can be used as a wrapping label, a glue label, an in-mold label, or the like.
As shown in FIG. 15, for example, the single-wafer-shaped label E is attached so as to be wrapped around an adherend 9 such as a container. The label E by such a mounting method is also called a wrapping label. An adhesive is applied to the back surface of at least one end E1 of the wrapping label E, and as shown in FIG. 15A, the one end E1 is attached to an adherend 9 such as a container, and the wrapping label is used. After wrapping E around the adherend 9, as shown in FIG. 15B, the back surface of the other end E2 is attached to the surface of one end E1 (or the other end E2). The back surface of the article F is attached to the adherend 9) to obtain the labeled article F.
