Description

本発明は、立体視または可変視用の印刷画像もしくは印刷図柄・模様が見えるようにしたレンズ付き印刷物に関し、さらに詳細には、画像もしくは図柄・模様に独自の変化を与える立体感や加飾効果に優れるレンズ付き印刷物に関するものである。   The present invention relates to a printed image with a lens so that a printed image or printed pattern / pattern for stereoscopic vision or variable vision can be seen, and more specifically, a stereoscopic effect and a decoration effect that give an original change to the image, the pattern / pattern, or the like. It is related with the printed matter with a lens which is excellent in.

従来から、例えば、特許文献1で提案されているように、印刷等により平面的に視覚表現された絵や図柄等の画像(「立体視用の画像」)をレンチキュラーレンズを用いて立体的に視認できるようにした立体印刷物はよく知られている。この立体印刷物は、左右の目で像を結ぶことができる立体視用の画像をレンチキュラーレンズの微細な凸レンズ列と同じ間隔(ピッチ)で線状に配列し、立体画像として認識することができるようにしたものである。   Conventionally, for example, as proposed in Patent Document 1, an image such as a picture or a pattern visually expressed in a planar manner by printing or the like (“stereoscopic image”) is stereoscopically displayed using a lenticular lens. Three-dimensional printed materials that can be visually recognized are well known. This three-dimensional printed product can be recognized as a three-dimensional image by arranging three-dimensional images that can form an image with the left and right eyes in a line at the same interval (pitch) as the fine convex lens array of the lenticular lens. It is a thing.

また、レンチキュラーレンズに、2種類3種類以上の絵や図柄等をこのレンズの微細な凸レンズ列の間隔(ピッチ)に合わせて交互にまたは種類順に繰り返して短冊状に合成した画像(「可変視用の画像」)を配設し、見る角度によって2種類または数種類の異なる絵柄が見えるようにした可変印刷物もよく知られている。   In addition, two or more types of pictures and designs on a lenticular lens are synthesized in a strip shape alternately or according to the type in accordance with the interval (pitch) of the minute convex lens array of this lens ("for variable vision" Also known are variable prints in which two or several different images can be seen depending on the viewing angle.

従来、上記の立体視または可変視印刷物は、平面の画像に遠近感や立体感を与えたり、動作変化を与える印刷物の技法として、あらかじめ複数の画像を縦方向または横方向に多数の線状帯に分け、これら異なる画像の線状帯を順次に並べて一枚に印刷し、その上に線状帯のピッチと方向に合わせたかまぼこ状の微細レンズの集合体からなるレンチキュラーシート等のレンズ作用により、複数の画像を重ね合わせ普通の視覚距離で結合して見せ、画面に立体感を出したり、画面を傾けることにより画像の変化を与える方法が取られている。画面を傾けて画像の変化を与える場合、画面にはめ込むかまたは分割して異なった2つの画像を一枚に印刷し、レンチキュラーシートを張つけても、傾きによるそれぞれの画像の変化は同一で、それぞれの画像に独自の変化を与えることは出来なかった。
特許第3038329号公報
Conventionally, the above-described stereoscopic vision or variable vision printed material is a technique for a printed material that gives perspective or stereoscopic effect to a flat image or changes its operation. The linear bands of these different images are sequentially arranged and printed on one sheet, and the lens action such as a lenticular sheet made of an assembly of kamaboko-shaped microlenses aligned with the pitch and direction of the linear bands on it. A method is used in which a plurality of images are superimposed and combined at an ordinary visual distance to give a three-dimensional effect to the screen or to change the image by tilting the screen. When tilting the screen to give an image change, even if the two different images are printed on one sheet and divided into one sheet, and the lenticular sheet is attached, the change in each image due to the tilt is the same, Each image could not be given its own changes.

Inserted into and placed in the press molding machine (50), heated and pressed under a predetermined temperature condition, and the uneven shape (61) is formed into a corrugated shape on the stereoscopic or variable vision image sheet (1) side of the printed matter with lens. Following (61), the irregularities were transferred and shaped, and then cooled under predetermined cooling conditions, and the irregularities (61) were fixed to provide irregularities, as shown in FIG. Can be printed with a lens.

本発明における凹凸形状の深さが0.003mm〜10mmの範囲で、ピッチが0.005mm〜100mmの範囲が望ましい。   In the present invention, the depth of the concavo-convex shape is preferably in the range of 0.003 mm to 10 mm, and the pitch is preferably in the range of 0.005 mm to 100 mm.

本発明のレンズ付き印刷物の立体視または可変視画像シート(1)のレンズ部(1a)は、紫外線硬化型樹脂で形成されているので加熱押圧工程でレンズが潰れることがないので立体視または可変視が可能である。また、本発明のレンズ付き印刷物の画像の印刷は紫外線硬化型インキを用いて形成するした方が上記の加熱押圧工程で印刷画像の変形を防止できる点において望ましい。   Since the lens portion (1a) of the stereoscopic or variable vision image sheet (1) of the printed matter with a lens of the present invention is formed of an ultraviolet curable resin, the lens is not crushed in the heating and pressing step, so that it is stereoscopic or variable. Visible. In addition, it is desirable to print an image of a printed matter with a lens according to the present invention using an ultraviolet curable ink in that the deformation of the printed image can be prevented by the heating and pressing step.

上記で得られる本発明のレンズ付き印刷物は、立体視または可変視画像シート側に凹凸形状が形成されているので、従来の凹凸形状が施されていない平坦状のレンズ付き印刷物では得られない、画像もしくは図柄・模様に独自の変化を与える立体感や加飾効果に優れるレンズ付き印刷物を提供できる。したがって、本発明のレンズ付き印刷物は観る者の注目を集め易く、パッケージ、カード、ポスター、景品等に使用して宣伝や差別効果の高いものとなる。また、絵本や雑誌等に用いても利用価値の高いものとなる。   The printed matter with a lens of the present invention obtained above has a concavo-convex shape formed on the stereoscopic or variable vision image sheet side, so it cannot be obtained with a conventional flat lenticular printed product that has not been provided with a concavo-convex shape. It is possible to provide a printed matter with a lens that is excellent in three-dimensional effect and decoration effect that gives an original change to an image or a pattern / pattern. Therefore, the printed matter with a lens of the present invention easily attracts the viewer's attention, and is used for a package, a card, a poster, a prize, etc., and has high advertising and discrimination effects. Moreover, even if it is used for a picture book, a magazine, etc., it will have a high utility value.

本発明のレンズ付き印刷物の一例として、波形形状の凹凸が形成されているレンズ付き印刷物を示す模式断面図である。It is a schematic cross section which shows the printed matter with a lens in which the waveform unevenness | corrugation is formed as an example of the printed matter with a lens of this invention. レンズ付き印刷物に波形形状凹凸が形成される前の平担状のレンズ付き印刷物の一部分を示す模式拡大断面図である。It is a model expanded sectional view which shows a part of flat printed matter with a lens before waveform shape unevenness | corrugation is formed in a printed matter with a lens. 本発明のレンズ付き印刷物に用いられるレンチキュラーレンズの一例を示す模式斜視図である。It is a model perspective view which shows an example of the lenticular lens used for the printed matter with a lens of this invention. 本発明のレンズ付き印刷物に用いられるマイクロレンズアレイの一例を示す模式斜視図である。It is a model perspective view which shows an example of the micro lens array used for the printed matter with a lens of this invention. 本発明のレンズ付き印刷物の一例としてマイクロレンズアレを用いたドットパターンが立体視される例を説明するための模式説明図である。It is a schematic explanatory view for explaining an example in which a dot pattern using a microlens array is stereoscopically viewed as an example of a printed matter with a lens of the present invention. 本発明のレンズ付き印刷物に形成される凹凸形状を形成する方法の一例を説明するための模式断面図である。It is a schematic cross section for demonstrating an example of the method of forming the uneven | corrugated shape formed in the printed matter with a lens of this invention.
