[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
In the three-dimensional / variable printing jigsaw puzzle and the method of manufacturing the same according to the present invention, the lenticular lens portion is preferably formed of a lenticular lens having a thickness of 0.2 to 3.0 mm and a lens pitch of 20 to 150 lines / inch. The production method is not limited, and for example, a commercially available product may be used. When the thickness is smaller than the above range, hardness and waist (stiffness) are insufficient, so that it is easy to bend and the handleability as a piece deteriorates. Conversely, if the thickness is larger than the above range, it is difficult to handle and the material cost increases. In the first aspect of the present invention, a jigsaw puzzle piece is constituted by the lenticular lens itself.
[0009]
In the first aspect of the present invention, a picture whose image is decomposed in accordance with the lens pitch of the lenticular lens is formed on the surface of the mount case in which the piece is fitted. Specifically, the image-decomposed pattern may be directly printed on the surface of the mount case, or paper or a plastic sheet on which the image-decomposed pattern is printed may be bonded to the surface of the mount case.
[0010]
Since computer software for decomposing a three-dimensional / variable image color original according to the lens pitch is already commercially available, plate making and printing may be performed using this software, and a dot density of 150 to 700 lines / inch may be obtained. It is desirable that the printing be performed, and the printing can be performed by oil-based printing, UV offset printing, silk printing, gravure printing, flexographic printing, or the like by means such as on-demand printing. Here, the lens pitch refers to the pitch of the lenticular lens.
[0011]
The three-dimensional / variable printing jigsaw puzzle according to the first aspect of the present invention can be created by the following procedure.
First, a lenticular lens having a thickness of 0.2 to 3.0 mm and a lens pitch of 20 to 150 lines / inch is prepared, and an image-decomposed pattern is formed on the surface of the mount case in accordance with the lens pitch of the lenticular lens.
Next, the backing case is laminated below the lenticular lens, and in that state, half blanking is performed from above. Thereby, the lenticular lens becomes a divided jigsaw puzzle piece.
[0012]
In the three-dimensional / variable-printing jigsaw puzzle according to the first aspect of the present invention, since the pieces of the jigsaw puzzle are formed of transparent lenticular lenses, the jigsaw puzzles are fitted as compared with the case of combining pieces having ordinary patterns formed thereon. In some cases, sophisticated considerations are required, and the entertainment becomes more enjoyable. Then, the completed image obtained by fitting is a three-dimensional / variable image having a high visual effect and a high design effect, and has a high decorative effect when hung on a wall or the like.
[0013]
Also in the second aspect of the present invention, the jigsaw puzzle piece is constituted by the lenticular lens. In this case, a picture whose image is decomposed in accordance with the lens pitch of the lenticular lens is formed on the back surface side. ing. Specifically, on the back of the lenticular lens, the image-decomposed pattern may be printed directly using the back printing method, or paper or a plastic sheet on which the image-decomposed pattern is printed may be printed on the back of the lenticular lens. You may stick them together. In the case of backing paper or a plastic sheet, an adhesive layer or an adhesive layer is formed on the printing surface.
[0014]
The three-dimensional / variable printing jigsaw puzzle according to the second aspect of the present invention can be created by the following procedure.
First, a lenticular lens having a thickness of 0.2 to 3.0 mm and a lens pitch of 20 to 150 lines / inch is prepared, and on the back surface, a pattern whose image has been decomposed according to the lens pitch of the lenticular lens is formed by a back printing method. Form.
Next, a mount case is laminated below the lenticular lens, and in that state, a half blanking process is performed from above. Thereby, the lenticular lens becomes a divided jigsaw puzzle piece.
[0015]
In the three-dimensional / variable-printing jigsaw puzzle according to the second aspect of the present invention, the jigsaw puzzle piece is formed of a lenticular lens, and a picture whose image is decomposed is formed on the back surface thereof. The variable image is formed, the visual effect and the design are higher than the piece on which the normal pattern is formed, and the entertainment is more enhanced. Then, the completed image obtained by fitting is a continuous three-dimensional / variable image, which is hung on a wall or the like and has a high decorative effect.
[0016]
Further, the lenticular lens layer may be formed by silk screen printing. That is, a regular uneven pattern may be formed on the surface of the transparent sheet material by silk screen printing at 20 to 150 lines / inch so that the concave portion has a smooth portion having a width of 1 to 50 μm. Alternatively, it may be created by pressing a sheet.
[0017]
As a transparent sheet material used in that case, a sheet made of polyvinyl chloride, polycarbonate, polyester, acrylic resin, polystyrene, polypropylene, polyethylene, ABS resin, biodegradable resin, or the like, or synthetic paper can be used. As a matter of course, a transparent or translucent type paper is used as the synthetic paper.
[0018]
The regular concavo-convex pattern is for forming a lenticular lens layer on the surface of the transparent sheet material, and is formed at 20 to 150 lines / inch as described above. On the other hand, the concave portion (on the bottom surface) is formed to have a smooth portion having a width of 1 to 50 μm. By forming such a smooth portion, the pattern is clear, and the displacement, moiré phenomenon, blur, blur, and the like can be significantly reduced, and excellent design can be obtained.
[0019]
The ink used in the silk screen printing for forming the above-described regular uneven pattern is not particularly limited as long as it has high transparency and forms an uneven pattern without performing processing such as embossing. For example, a Braille ink or the like can be suitably used. More specifically, UV Clear POT5020, manufactured by Teikoku Ink Co., Ltd., an improved Braille ink manufactured by Seiko-Advance, or an improved shrink printing ink manufactured by Toyo Ink can be used. In these printings, it may be important to control the temperature strictly, for example, at 25 ° C. ± 5 ° C., or to control the viscosity of the ink.
[0020]
In the third and fourth aspects of the present invention, as described above, the jigsaw puzzle pieces are constituted by transparent or translucent dod lens sheets. Then, in the third mode, a three-dimensional / variable image is developed by being combined with a picture printing provided with a halftone dot printing section formed on the mount case. In the fourth embodiment, a picture print is formed on the back surface of the jigsaw puzzle piece, a three-dimensional / variable image is given to the piece itself, and basically no picture print is given to the mount case.
[0021]
The jigsaw puzzle piece according to the third aspect of the present invention is constituted by a transparent or translucent dod lens sheet, but by itself, it is simply a transparent or translucent film, and can be superimposed on a normal printed matter. It does not provide any visual effect. In addition, the pattern printing provided with the halftone printing portion formed on the backing case is not what has a stereoscopic image at all by itself, but is a mere printed matter, and when it is closely observed, fine halftone printing is performed. It is the degree to which it is visually recognized. Then, by combining these, that is, by bringing them into close contact, a stereoscopic image is developed. Therefore, fitting into a specified position in the first place is interesting as a jigsaw puzzle, but after being fitted, a pattern as a mere printed matter formed on a mount case is expressed as having a stereoscopic image. With the completion of the jigsaw puzzle, it becomes interesting to obtain a highly decorative ornament.
[0022]
The jigsaw puzzle piece according to the fourth aspect of the present invention is constituted by a transparent or translucent dod lens sheet, but is provided with a pattern printing provided with a halftone dot printing portion on the back surface thereof, and is itself a three-dimensional image. Visual image appears. Then, with the completion of the jigsaw puzzle, it is possible to obtain an interesting feature that it becomes a highly decorative ornament.
[0023]
In the third aspect and the fourth aspect, the picture print on which the halftone dot printing section is formed, even if it appears to be a single-color solid print, can be obtained by combining parts having partially different halftone frequencies. By creating and applying this to the jigsaw puzzle (mounting case or piece), halftone dots of partially different sizes will give different stereoscopic sensations, exhibiting a very strange decorativeness that has never been seen before. Become. By appropriately selecting the color relationship between the halftone dot and the background color, it is possible to make it appear as if a hidden pattern appears.
Furthermore, when the pattern printing is made into two or more kinds of multicolor printed matter, and one or more of them (one color) is made into a halftone printing part (hereinafter, a normal printing part is called a flat printing part), for example, it becomes a six-color multicolored printed matter When applied to the jigsaw puzzle as a halftone dot printing portion for the three color picture portions, the flat printing portion constituting the three color picture portion looks flat, and the halftone dot printing portion constituting the remaining three color picture portions has a deepness. Is obtained. That is, the stereoscopic image becomes more prominent as compared with the printed matter formed only by the halftone dot printing section, and the decoration effect becomes higher. In particular, by making the halftone printing portion and the flat printing portion adjacent to each other, a stereoscopic image becomes prominent.
[0024]
Also, by controlling the dot pattern of the dot lens sheet with respect to the dot printing section of the picture printing, or controlling the dot of the dot printing section of the picture printing with respect to the dod pattern of the dot lens sheet, It is also possible to use a partially emphasized pattern. In particular, the latter control method can be easily performed.
[0025]
When the coating is performed with a transparent paint or the like exceeding the depth of the groove of the dod lens sheet, the transparency itself is not impaired, but the magnifying effect (lens effect) of the lens sheet is lost only in that portion. That is, in the case of a base material which is partially coated or laminated as a dod lens sheet exceeding the groove depth of the lens sheet, only that portion becomes a mere transparent film. Therefore, when a piece is formed from this base material and applied to the jigsaw puzzle, the part where coating or lamination is partially performed is seen as a mere flat shape, but the stereoscopic image is more prominent. And the decorative effect is higher.
[0026]
In the present invention, a stereoscopic image appears when the number of lines (m) of the halftone dot printing part of the picture printing and the number of lines (n) of the dod lens sheet forming the piece have the following relationship. I found that.
n = 50 to 150, m = (1/2/3/2) × n, m ≠ n
For example, when n = 50, m = 25 to 75, where m ≠ 50,
When n = 100, m = 50 to 150, where m ≠ 100,
When n = 130, m = 65-195, where m ≠ 130,
When n = 150, m = 75-225, where m ≠ 150.
Outside the above range, a stereoscopic image does not appear or becomes extremely blurred, has no eye catching effect, and does not have a rich visual interest.
[0027]
