Description

  The present invention relates to a printed material that forms a three-dimensional image, and more particularly, to a three-dimensional printed material in which a three-dimensional image is formed using moire and a technique of a manufacturing method of the three-dimensional printed material.

Among printed materials typified by sheets and stickers, a three-dimensional printed material is known in which an image printed according to the angle and distance at which the printed material is viewed is viewed three-dimensionally. As this three-dimensional printed material, a technique is widely adopted in which a lenticular lens made up of an assembly of cylindrical lenses (kamaboko-shaped fine lenses) is bonded and a three-dimensional effect is formed by the action of the lenticular lens. That is, the three-dimensional printed material is formed as a single printed material (hereinafter referred to as a lenticular printed material) by superimposing a plurality of lenticular lenses on which a predetermined image is printed.
As a technique using the lenticular lens described above, there is a combination of a transmissive lenticular print and a print for alignment, and this can be achieved by changing the combination of the transmissive lenticular print and the print for alignment. There is a technique that enables synthesis (see, for example, Patent Document 1).

JP 2000-275754 A

On the other hand, when the lenticular printed material was used, the following inconvenience occurred. As described above, the lenticular printed material is formed as a single printed material by superimposing a plurality of image sheets. Therefore, the cost per sheet is higher than that of a normal printed matter.
In addition, when the lenticular printed material is a printed material with a sealing function, the object to be bonded to the lenticular printed material is not flat but curved or has a corner. It was virtually impossible to attach. This is because the lenticular printed material is thicker than a normal printed material and is not suitable for a form in which the lenticular printed material is folded and pasted.
Therefore, there has been a demand for a technique for a three-dimensional printed matter after solving the above-described problems. That is, a three-dimensional printed material that forms an excellent three-dimensional image with a simple configuration, and a three-dimensional printed material that can flexibly cope with the shape of the object has been desired.

The present invention has been made in view of the above-described problems. That is, an object of the present invention is to provide a three-dimensional printed material that forms an excellent three-dimensional image with a simple configuration and can flexibly cope with the shape of an object.
The invention described in claims 1 to 7 is a three-dimensional printed material that forms an excellent three-dimensional image with a simple configuration, and provides a three-dimensional printed material that can flexibly cope with the shape of an object.
The invention according to claim 8 is a three-dimensional printed material that forms an excellent three-dimensional image with a simple configuration, and provides a method for producing a three-dimensional printed material that can flexibly cope with the shape of an object.

In order to solve the above-mentioned problem, in the present invention according to claim 1, the lower surface located below the transparent sheet (20) printed with a regular pattern having regularity through the bent portion (21). A three-dimensional printed material (10) comprising a sheet (22) and an upper surface sheet (23) positioned above the lower surface sheet (22), and a general image (30) printed on a part of the transparent sheet (20). )I will provide a.
That is, the lower surface ground portion (22a) in the lower surface sheet located at the end opposite to the bent portion (21), and the upper surface in the upper surface sheet (23) provided at a position corresponding to the lower surface ground portion (22a) By bending the grounding portion (23a) with the bent portion (21) as a grid, the portion other than the lower surface grounding portion (22a) in the lower surface sheet (22) and the upper surface grounding portion (23a) in the upper surface sheet (23) 3D printed matter fixed so as to form a moire forming space (50) between the other portions.

(Glossary)
The “transparent sheet (20)” is a sheet-like printed material represented by a transparent film or the like. As this permeable sheet (20), for example, a very thin film sheet is used.
The “regular pattern” is a pattern formed by regularly arranging dots and lines. The upper sheet (23) and the lower sheet (22) are printed on the upper sheet (23) and the lower sheet (22), but before the bent portion (21) is formed, the upper sheet (23) and the lower sheet (22) are one continuous sheet. Therefore, in general, the upper sheet (23) and the lower sheet (22) are not printed separately, but are printed in one step.
The “general image (30)” is an image formed by characters or patterns. Further, the “part of the transparent sheet” on which the general image (30) is printed may be a part of the lower surface sheet (22) or a part of the upper surface sheet (23). Alternatively, it may be printed across the lower sheet (22) and the upper sheet (23).
Moreover, although specified by another claim, the image formed by changing only the angle of a regular pattern is also included.
The “folded portion (21)” is a fold line provided at the boundary between the lower surface sheet (22) and the upper surface sheet (23).
The “moire forming space (50)” is a space provided for forming a moire generated by printing a regular pattern on the transparent sheet (20) and overlapping the regular pattern.
As a pattern for forming the moire forming space (50), when the upper sheet (23) swells with respect to the flat lower sheet (22), the lower sheet (22) with respect to the flat upper sheet (23). In some cases, the bottom sheet (22), the top sheet (23), or both have a wavy shape.

(Function)
A regular pattern is printed on the top sheet (23) and the bottom sheet (22) of the permeable sheet (20). Further, a general image is printed on a part of the transparent sheet. The lower surface grounding portion (22a) of the lower surface sheet (22) and the upper surface grounding portion (23a) of the upper surface sheet (23) are folded using the folding portion (21) as a grid. It is fixed so that a moire forming space (50) is formed between a portion other than the lower surface ground portion (22a) and a portion other than the upper surface ground portion (23a).
That is, by fixing the lower surface grounding portion (22a) and the upper surface grounding portion (23a) so that the moire forming space (50) is formed, the regular patterns of the upper surface sheet (23) and the lower surface sheet (22) are formed. Moire occurs due to overlapping. For this reason, when the transparent sheet (20) is viewed through the moire forming space (50), a 3D effect is produced. In other words, a simple structure in which a regular pattern is printed on the transparent sheet (20), and a moire forming space (50) is provided and stacked, and a stereoscopic image can be formed without using a conventional lenticular print. A print (10) can be provided. Further, since the permeable sheet (20) is formed of a thin film sheet, it can be relatively freely deformed and can be bonded according to the shape of the object.

Invention of Claim 2 limited the three-dimensional printed matter of Claim 1,
The upper surface grounding portion (23a) is provided with an elongated glue white (24) having a V-shaped cross section by folding back an end of the upper surface grounding portion (23a). (22a) is characterized in that a moire forming space (50) is formed between a portion other than the glue white (24) and a portion other than the lower surface grounding portion (22a).

(Glossary)
The “glue scissors” are formed so as to have a space when the lower surface grounding portion (22a) and the upper surface grounding portion (23a) are fixed. The V-shaped cross section can be easily achieved by adopting a material such as a thermoplastic resin of the permeable sheet (20), for example. Since the glue sheet (24) is formed by being bent at a predetermined interval from the end, the thickness of the moire forming space (50) is increased.
(Function)
According to the second aspect of the present invention, the glue white (24) provided on the upper surface grounding portion (23a) is different from the lower surface grounding portion (22a) in terms of the portion other than the glue white (24) and the lower surface grounding portion ( It is fixed so that a moire forming space (50) is formed between the parts other than 22a). By forming in this way, it becomes easy to fix the lower surface grounding portion (22a) and the upper surface grounding portion (23a). In addition, the overall shape of the three-dimensional printed material (10) is rounded, which is excellent in aesthetics.

Invention of Claim 3 limited the three-dimensional printed matter of Claim 1,
The lower surface grounding portion (22a) is provided with an elongated glue white that is folded back at the end of the lower surface grounding portion (22a), and the adhesive white is a portion other than the glue white relative to the upper surface grounding portion (23a). A moire forming space (50) is formed so as to form a portion other than the upper surface grounding portion (23a).

(Function)
According to the third aspect of the present invention, the glue white provided on the lower surface grounding portion (22a) has a portion other than the glue white and a portion other than the upper surface grounding portion (23a) relative to the upper surface grounding portion (23a). The moire forming space (50) is fixed between the two.
In the present invention, the position of the glue white specified in the invention of claim 2 is turned upside down. That is, as specified in claims 2 and 3, it may be formed on either the lower surface ground portion (22a) or the upper surface ground portion (23a), or may be provided on both.

  Invention of Claim 4 limited the three-dimensional printed matter of Claims 1-3, and was printed on the regular pattern and upper surface sheet (23) which were printed on the said lower surface sheet (22). The regular pattern is characterized by being formed with the same regular pattern.

(Function)
According to the invention described in claim 4, the regular pattern of the upper surface sheet (23) and the regular pattern of the lower surface sheet (22) are formed in the same regular pattern. By using the same regular pattern, moire surely occurs and an excellent stereoscopic image can be formed.

Invention of Claim 5 limited the three-dimensional printed material in any one of Claim 1 to Claim 4,
The general image (30) is printed on the top surface and the back surface of the top sheet (23),
The pattern shape of the general image (31) printed on the upper surface and the pattern shape of the general image (32) printed on the back surface are formed differently and printed on the upper surface of the upper surface sheet (23). The general image (31) is formed so that the general image (32) printed on the back surface cannot be seen through.
For example, the general image (31) printed on the upper surface of the upper surface sheet (23) cannot be seen through the general image (32) as an opaque image. As a result, it is not possible to confirm what the general image (32) printed on the back side is unless the folding part (21) is turned back.

(Function)
According to the fifth aspect of the present invention, in a state where the upper sheet (23) covers the lower sheet (23) by the bent portion (21), the general image printed on the upper surface of the upper sheet (23) ( Only the image 31) can be seen, and it cannot be confirmed what the general image (32) printed on the back side is. Therefore, by returning the folding of the bent portion (21), for example, by removing the glue white (24), it can be used for purposes such as “wrinkle drawing”.

Invention of Claim 6 limited the three-dimensional printed matter in any one of Claims 1-5,
The general image (30) is formed as an irregular pattern in which only the angle of the regular pattern is changed.

(Function)
According to the invention described in claim 6, the general image is formed as an irregular pattern in which only the angle of the regular pattern is changed. When formed in this way, a regular image that has an irregular pattern by changing only the angle has a form in which only the angle is changed, so it is difficult to distinguish the regular pattern printed on the transparent sheet from the regular image. It becomes. For this reason, for example, it can also be used for security applications using a three-dimensional printed material.

The invention according to claim 7 limits the three-dimensional printed material according to any one of claims 1 to 6,
The permeable sheet (20) is provided on a separate sheet having an adhesive function.

(Function)
According to the invention described in claim 7, the permeable sheet (20) on the separate sheet can be adhered to the object because the separate sheet has an adhesion function. For this reason, for example, it may be used as a POP for sales promotion, or may be used as a seal for toys.

A procedure for printing a general image on a part of the transparent sheet, a lower surface grounding portion on the lower surface sheet located at the end opposite to the bent portion, and a position corresponding to the lower surface grounding portion A moiré forming space between the upper surface grounding portion of the upper surface sheet provided on the upper sheet and the procedure of bending the bent portion as a grid, and a portion of the lower surface sheet other than the lower surface grounding portion and a portion of the upper surface sheet other than the upper surface grounding portion And a method of manufacturing a three-dimensional printed material by a procedure of fixing so as to form.

(Function)
According to invention of Claim 8, a regular pattern is printed on the upper surface sheet and lower surface sheet | seat of a permeable sheet. A general image is printed on a part of the transparent sheet. The lower surface grounding portion of the lower surface sheet and the upper surface grounding portion of the upper surface sheet are folded using the folded portion as a grid. It fixes so that the space for moire formation may be formed between parts other than a lower surface grounding part and parts other than an upper surface grounding part.
By using the manufacturing method as described above, a moire forming space is formed inside the transparent sheet, and by folding the transparent sheet, a regular pattern overlapping through the space forms a three-dimensional image. Become. For this reason, when the transparent sheet is viewed through the moire forming space, a three-dimensional effect is produced. Further, since the permeable sheet is formed of a very thin film sheet, it can be relatively freely deformed, and can be bonded according to the shape of the object.

It was.

  Hereinafter, the present invention will be described in more detail based on the embodiments of the present invention shown in the drawings. The drawings used here are FIGS. 1 to 7. FIG. 1 is a plan view showing a configuration of a three-dimensional printed material, FIG. 2 is a plan view showing a state where the transparent sheet of FIG. 1 is folded, and FIG. 3 is a perspective view of the three-dimensional printed material viewed from the side. FIG. 4 is a front view of a three-dimensional printed material, (a) and (b) are diagrams showing a 3D effect when viewed from different viewpoint angles, and FIG. 5 is a three-dimensional printed material. (A) And (b) is a figure which showed how a stereoscopic image looks when it sees by changing the number of lines and a viewpoint angle.

(First embodiment)
As shown in FIG. 1, the three-dimensional printed material 10 has a transparent sheet 20 on which a regular pattern having regularity is printed on a separate sheet 90, and forms the three-dimensional printed material 10 as a whole. The permeable sheet 20 is provided with a bent portion 21 at a substantially central portion of the permeable sheet 20, a lower surface sheet 22 positioned below the bent portion 21, and an upper surface positioned above the lower surface sheet 22. The general image 30 is printed on a part of the transparent sheet 20. Further, the lower surface ground portion 22a in the lower surface sheet 22 located at the end opposite to the bent portion 21 and the upper surface ground portion 23a in the upper surface sheet 23 provided at a position corresponding to the lower surface ground portion 22a are folded portions. 21 is fixed so that a moire forming space 50 is formed between a portion other than the lower surface grounding portion 22a in the lower surface sheet 22 and a portion other than the upper surface grounding portion 23a in the upper surface sheet 23. Yes.
Here, the “regular pattern” is a pattern formed by regularly arranging dots, lines, and the like. In this embodiment, lines are used. The regular pattern is printed on the upper surface sheet 23 and the lower surface sheet 22, but before the bent portion 21 is formed, the upper surface sheet 23 and the lower surface sheet 22 are one continuous sheet. The sheet 23 and the lower surface sheet 22 are not printed separately, but are printed in one step.
In addition, the “transparent sheet” is a printed material formed in a sheet shape represented by a transparent film or the like. A very thin film sheet is used for the permeable sheet of this embodiment.
The separate sheet 90 is formed of a permeable film sheet, and a sealing function (adhesion function) is provided on the back surface opposite to the surface on which the permeable sheet 20 is pasted. This sealing function is used, for example, when the three-dimensional printed material 10 is attached to an object.

A plurality of general images 30 are printed on the lower surface sheet 22 and the upper surface sheet 23. The general image 30 includes a general image 31 printed on the top surface of the top sheet 23, a general image 32 printed on the back surface of the top sheet 23, and a general image 33 printed on the back surface of the bottom sheet 22. ing. Further, the general image 31 printed on the upper surface and the back surface of the upper surface sheet 23 is formed so that the pattern shape of the general image 31 printed on the upper surface is different from the pattern shape of the general image 32 printed on the back surface. The general image 31 printed on is formed so that the general image 32 printed on the back surface cannot be seen through.
For example, the general image 31 printed on the upper surface of the upper surface sheet 23 cannot be seen through the general image 32 as an opaque image. Accordingly, unless the folding portion 21 is returned, it is not possible to confirm what the general image 32 printed on the back side is. Therefore, by returning the folding of the bent portion 21, specifically, by removing the glue white 24, it can be used for applications such as “wrinkle drawing”.
In addition, although the general image 30 is printed on a part of the transmissive sheet, it may be a part of the lower sheet 22, a part of the upper sheet 23, It may be printed across the top sheet 23.

  Details of the permeable sheet 20 will be described with reference to FIG. The permeable sheet 20 is a transparent film formed of a transmissive or semi-transmissive material, and a regular pattern is printed on almost the entire surface of the permeable sheet. The regular pattern in this embodiment is formed by a plurality of vertical lines with an angle of ± 0 degrees, but the regular pattern itself is not particularly limited. That is, it is only necessary to be regularly distributed, and for example, a horizontal line, a diagonal line, and a dot pattern may be used. As shown in FIG. 2, when the transient sheet 20 is viewed in a plan view, the bent portion 21 extends in the width direction. In the present embodiment, the lower portion is defined as the lower surface sheet 22 and the upper portion is defined as the upper surface sheet 23 with the bent portion 21 as a reference. That is, the lower surface sheet 22 and the upper surface sheet 23 are formed with the same regular pattern.

Next, the form which bent the upper surface sheet | seat 23 is demonstrated. The permeable sheet 20 is shaped as shown in FIG. 2 by bending the top sheet 23 to the near side (the bottom sheet 22 side) of FIG. At the time of bending, the upper surface ground portion 23 a of the upper surface sheet 23 is fixed to the lower surface ground portion 22 a of the lower surface sheet 22 so as to form the moire forming space 50.
As the shape of the upper surface grounding portion 23a of the present embodiment, an elongated glue white 24 having a V-shaped cross section is provided by folding back an end portion of the upper surface grounding portion 23a. Here, the “glue scissors” are formed so as to have a space when the lower surface grounding portion 22a and the upper surface grounding portion 23a are fixed. The V-shaped cross section can be easily achieved by adopting a material such as a thermoplastic resin of the permeable sheet 20, for example.
Since the glue white 24 is formed by being bent at a predetermined interval from the end portion, a thickness is generated in the moire forming space 50. The glue white 24 is folded to the near side of FIG. 1 with the folded portion 24b as a reference, and has a form as shown in FIG. That is, the glue white 24 is fixed to the lower surface grounding portion 22a, so that the moire forming space 50 is formed in the permeable sheet 20. In addition, you may make it provide the glue white 24 in the lower surface grounding part 22a.

The moire forming space 50 has a shape in which opposite side surfaces are open and the upper surface sheet 23 draws a semicircle. Here, the “moire forming space” is a space provided for forming a moire generated by printing a regular pattern on a transparent sheet and overlapping the regular pattern. As a pattern for forming the moire forming space 50, when the upper surface sheet 23 swells with respect to the flat lower surface sheet 22, when the lower surface sheet 22 swells with respect to the flat upper surface sheet 23, There is a case where one or both of the top sheets 23 have a waved shape.
That is, when the upper surface sheet 23 is fixed to the lower surface sheet 22, the lower surface sheet 22 and the upper surface sheet 23 are overlapped to generate moire. Moire is a periodic striped pattern that can be formed by interference of pixels (dots) with each other when regular patterns are superimposed.

Hereinafter, it is the consideration result about the moire in the three-dimensional printed material 10.
FIG. 4 is a front view of FIG. 3, schematically showing a form in which a stereoscopic image is generated by overlapping the lower surface sheet 22 and the upper surface sheet 23. FIG. 4A shows a state in which the three-dimensional printed material 10 is viewed from the front. That is, when the lower surface sheet 22 and the upper surface sheet 23 on which the regular pattern is printed are overlapped via the moire forming space 50, the regular pattern of the transmissive sheet 20 becomes a three-dimensional image in which the regular pattern looks three-dimensional. FIG. 4B is a view seen from the front with the viewpoint angle being gentler than that in FIG. When the viewpoint angle is changed, it can be seen that, unlike the stereoscopic image of FIG.

5A and 5B show a form in which the number of lines of the regular pattern is increased in the regular pattern printed on the transmissive sheet 20. Also in FIG. 5, it can be understood that different stereoscopic images are generated in (a) and (b) by changing the viewpoint angle in the same manner as in FIG. In addition, although illustration is omitted, there are cases in which a three-dimensional image looks like a wood grain by changing the number of lines and the angle of the regular pattern.
Even if the lower surface sheet 22 and the upper surface sheet 23 are overlapped without providing the moire forming space 50, moire is generated, but it is not a three-dimensional image and is the same as the moire generated in a general printing process. It was a thing.

That is, as is apparent from the above consideration results, a lenticular printed material using a conventional lenticular lens with a simple configuration in which a regular pattern is printed on the transmissive sheet 20 and a moire forming space 50 is provided and stacked. A three-dimensional printed material that forms a three-dimensional image can be provided without using the.
Moreover, the permeable sheet 20 is affixed to the separate sheet 90, and can be bonded to the object by the sealing function of the back surface of the separate sheet 90. Since both the permeable sheet 20 and the separate sheet 90 are formed of very thin film sheets, they can be deformed relatively freely, and can be bonded according to the shape of the object. For example, even when the object has a cylindrical shape and the three-dimensional printed material 10 is affixed around the object, the object does not have a thickness like a lenticular lens, and thus can be easily affixed.

  4 and 5 are merely examples, and the stereoscopic image is not limited. In addition, stereoscopic images do not look the same due to various factors such as the surrounding environment such as light and dark, the viewpoint distance and viewpoint angle of the viewer. However, although there are individual differences, this is a printed matter that allows a person with normal vision to feel a three-dimensional effect.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. The three-dimensional printed material 100 according to the second embodiment includes a lower sheet 22 positioned below the transparent sheet 20 on which a regular pattern having regularity is printed via a bent portion 21, and the lower sheet 22. An upper surface sheet 23 located above, a general image 30 is printed on a part of the transmissive sheet 20, and a lower surface grounding portion 22a in the lower surface sheet 22 located at an end opposite to the bent portion 21; The upper surface grounding portion 23a of the upper surface sheet 23 provided at a position corresponding to the lower surface grounding portion 22a is bent using the bent portion 21 as a grid, so that the portion other than the lower surface grounding portion 22a and the upper surface of the upper surface sheet 23 are The point that the moire forming space 50 (not shown in FIG. 6) is formed between the portion other than the grounding portion 23a is fixed. It is exactly the same as the embodiment. However, the present embodiment is different from the three-dimensional printed matter of the first embodiment in that the thin glue white 24 obtained by folding back the separate sheet 90 and the end portion of the upper surface ground portion 23a is eliminated and the configuration is simple.

  That is, the moire forming space 50 necessary for forming a stereoscopic image is fixed only by the lower surface grounding portion 22a and the upper surface grounding portion 23a. If it does in this way, it contributes to simplification of the manufacturing process of three-dimensional printed matter.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. The three-dimensional printed material 200 in the third embodiment is the same as that in the second embodiment described above, but the shape of the general image is different. In other words, the general image 30a printed on the three-dimensional printed material 200 is formed as an irregular pattern in which the angle is changed with respect to the angle of the regular pattern printed on the transparent sheet 20, and only the angle is changed. Therefore, in the state before the lower surface sheet 22 or the upper surface sheet 23 is overlaid (the state shown in FIG. 6), the distinction between the regular pattern of the transparent sheet 20 and the general image 30a can be instantly visually recognized. It becomes difficult. For this reason, it can also be used as a security sheet using the three-dimensional printed material 200.

  For example, an example used for confirming the consistency of merchandise discount coupons often used in retail stores will be described. At the stage of creating the three-dimensional printed material 200, a text or image appealing to consumers, such as campaign contents and product information, is printed as an opaque general image. On the other hand, the date on which the product discount voucher was issued, the expiration date, the store's own mark, etc. are printed in the same area. This is an irregular pattern in which only the angle is changed to the regular pattern of the permeable sheet 20. The retail store stores the bottom sheet 22 for checking, and superimposes it when the consumer uses the product discount coupon, thereby preventing unauthorized use by confirming the irregular pattern. Further, the same pattern as the general image (the date of issue of the product discount coupon, the expiration date, and the store-specific mark) printed on the top sheet 23 may be printed on the check sheet of the retail store. This is because the accuracy can be increased by a deviation or the like at the time of overlapping.

It is a top view which shows the three-dimensional printed material which concerns on this invention. It is the top view which showed the state which bent the permeable sheet. It is the perspective view which looked at the three-dimensional printed material which concerns on this invention from the side surface. It is a front view of a three-dimensional printed matter, (a) and (b) are the figures which compared the three-dimensional image seen when changing a viewpoint angle, respectively. It is a front view of a three-dimensional printed matter, (a) and (b) are the figures which compared the three-dimensional image seen when changing the number of lines and a viewpoint angle, respectively. It is a top view which shows the three-dimensional printed matter of 2nd embodiment. It is a top view which shows the three-dimensional printed matter of 3rd embodiment.
