The present invention relates to a product label, a decorative sticker, and other pseudo-hologram printed matter that can provide a variety of visual effects similar to holograms, and a manufacturing method effective for mass production thereof.

Pseudo-holographic prints and methods for manufacturing the same that are close to the present invention are disclosed in Patent Documents 1 and 2.

The printed matter described in Patent Document 1 is capable of transmitting light having a large number of convex portions (3A) or concave portions (3B) on its surface, and a transparent layer (3) composed of a transparent varnish, and A reflective layer (5) having a light reflecting surface (5A) provided on the back surface side of the transmissive layer (3) and a plurality of colored layers provided between the transmissive layer (3) and the reflective layer (5). The colored portion (7A) is provided between the colored layer (7) discretely arranged by printing and the transmission layer (3) and the reflective layer (5), and the thickness dimension of the colored colored portion (7A). (T2) has the same thickness dimension, and is provided with a colorless portion (9) printed with a medium (colorless transparent ink) between adjacent colored colored portions (7A), and the colorless portion ( 9) is the structure provided in the part corresponding to the recessed part (3B) of the said transmission layer (3).

On the other hand, the pseudo-holographic printed matter described in Patent Document 2 is a light reflection layer (2) on the surface of the printing object (10), and a colored ink layer printed with colored ink on the upper layer of the reflection layer (2). A pseudo-hologram print (1) comprising (3) and a pseudo-hologram layer (4) which is printed with a transparent ink in a predetermined range on an upper layer of the colored ink layer (3),

The pseudo hologram layer (4) has a plurality of matte transparent ink parts (41) for reducing the light reflectance of the colored ink layer (3) and a plurality of matte transparent ink portions (41) for increasing the light reflectance of the colored ink layer (3). At least any two or more of the glossy transparent ink portion (42) and the plurality of blank portions (43) on which the matte transparent ink and the glossy transparent ink are not printed are configured.

Japanese Patent No. 6271855 JP, 2017-71137, A

However, in the structure of the printed matter described in Patent Document 1, in addition to the fact that the light transmission layer (3) formed by printing with the transparent varnish always has the concave portion (3B) on its surface, the colored layer ( Since the colorless part (9) of 7) is printed with a medium (colorless transparent ink) in the same thickness dimension as the thickness dimension (T2) of the colored portion (7A), the light transmission layer (3) It is difficult to secure a large height difference between the convex portion (3A) and the concave portion (3B) in (4), and the light is merely scattered.

Further, there is no description that the convex portion (3A) of the transparent layer (3) is a line. Moreover, there is no explanation that the colored portion (7A) of the colored layer (7) is printed as a line consisting of colored image lines of different coloring colors.

Therefore, even if the colored portion (7A) of the colored layer (7) is printed in a striped pattern, if the parallel lines and the intersecting lines forming the striped pattern are in a thick solid printing state, complicated and various color tones are obtained. It is not possible to obtain a visual effect that is rich in a sense of change and is luxurious.

On the other hand, the pseudo-holographic printed matter described in Patent Document 2 has a blank portion (43) on which transparent ink is not printed, but has a matte transparent ink portion (41) and a glossy transparent ink portion (42) having different light reflectances. By arranging at least any two or more of the blank portion (43) and the colored ink layer (3), a three-dimensional illusion is given to the observer.

Therefore, when the colored ink of the colored ink layer (3) is a single color, the change of the color tone cannot be obtained even if the change of the shade is obtained, and much less the color ink of the colored ink layer (3) is used for printing. Since the image such as the designed pattern or characters is not divided and formed from the lines, it is impossible to obtain a pseudo-hologram printed matter rich in complex and various color changes and high quality.

Further, as a method for producing the printed matter, in addition to the colored ink printing step (S1), a matte transparent ink printing step (S2) and a glossy transparent ink printing step (S3) performed thereafter are necessary, and the matte transparent ink Both the transparent glossy ink and the glossy transparent ink must be printed so as not to overlap the character portion printed by the colored ink, which is very troublesome and cannot exert the mass production effect.

The present invention aims to improve such a problem, and in order to achieve the object, in claim 1, as a structure of a pseudo-holographic print, a printing substrate having a light reflecting layer on the front surface or a light reflecting layer on the back surface is provided.

It is sufficient if there are a total of two (two columns) colored drawing lines.

Further, the line width (thickness) (W1) of the colored image lines (12a) (12b) (12c) forming one set (1 unit) is, for example, 0.04 mm, and all of the plurality are set to be the same. , The plurality of adjacent pitches (D1) are all set to be the same, for example, 0.12 mm, but as suggested by FIGS. The interval pitch (D2) where the two are adjacent to each other is not limited to the same as the interval pitch (D1) (0.12 mm illustrated above) between the adjacent colored image lines forming one set (1 unit), and In some cases, the difference may be wider or narrower than this.

Further, (13) is a set (1 unit) consisting of a plurality of parallel colored image lines (12a) (12b) (12c) in the colored underlayer (12), and the entire set from the front side as shown in FIGS. Which is a transparent coating layer for selectively coating, and which has a line width (W2) (thick) wider than the line of the colored base layer (12) and has a plano-convex lens shape or a kamaboko shape. It is printed on 10) with a transparent varnish.

In that case, the line widths (thicknesses) (W2) of the lines forming the transparent coating layer (13) are all set to be the same, for example, 0.24 mm, but the transparent coating layers (13) are adjacent to each other. Is in a separated state in which all the same pitches (D3) of 0.12 mm are maintained, and the space between adjacent ones is left as an unprinted blank portion (14). The surface of the printing substrate (10) is exposed.

In the first embodiment of FIGS. 1 to 4, as described above, the line width (thickness) (W1) of the colored image lines (12a) (12b) (12c) forming one set in the colored underlayer (12) is the same. A plurality (three in the illustrated example) are all set to be the same, and the plurality of adjacent pitches (D1) are also set to the same, but as shown together with the modified embodiment of FIG. The line widths (thicknesses) (W1) of the colored image lines (12a) (12b) (12c) and/or the adjacent pitches (D1) may be all different from each other. Even if these are different, it is sufficient that each of the above-mentioned sets is in the same arrangement state and is composed of lines which are regularly and spacedly repeated. According to the modified embodiment of FIG. 5, it is useful to obtain a change in shading or enhancement degree (strength) in the colored lines (12a) (12b) (12c) of the colored underlayer (12).

Further, in the first embodiment of FIGS. 1 to 4, a plurality of different colored image lines (12a) (12b) (12c) forming a set in the colored underlayer (12) are adjacent to each other at a constant pitch (D1). If the total of two colored lines of at least two different colors are arranged in parallel with each other, it is clear from another modified embodiment of FIG. 6, for example, the cyan line (12a). ) And a magenta image line (12b) are in contact with each other without a space between them (in other words, non-overprinting state), or as shown in yet another modified embodiment of FIG. It is also possible to set the state of (12b) and the image line (12c) of yellow to be overlaid on each other. According to the modified embodiment of FIG. 7, a mixed color tone (for example, orange color) of the two different colors can be obtained.

Further, in the first embodiment of FIGS. 1 to 4, as is imperceptible from the schematic overall view of FIG. 1, the lines forming the colored underlayer (12) and, by extension, a plurality of different colored image lines. The thick lines of the transparent coating layer (13), which covers the entire set of (12a), (12b), and (12c) as a whole, are arranged in the same vertical direction (vertical direction) as the arrangement angle of 90 degrees. By arranging them in parallel along each other, a pseudo hologram print (A) displaying one decorative line image (vertical stripe pattern) (P) as a whole is finished. , 9 of the second and third embodiments, by making the array angle of the lines in the colored underlayer (12) different, a plurality of identifiable first to third decorations made of the different lines are provided. Even if the line images (P1) (P2) (P3) and the first to fourth decorative line images (P1) (P2) (P3) (P4) are finished as a pseudo hologram print (A) displayed in a non-overprint state. good.

In this regard, in the second embodiment of FIG. 8, the lines or the background of the second and third decorative line images (P2) and (P3) are defined by the lines having the arrangement angle of 90 degrees (vertical direction) in the colored underlayer (12). The first decorative line image (line pattern) (P1) that becomes a pattern, and the second line of the elliptical ring shape that is inclined to the left by the line with the array angle of 45 degrees to the right (inclination direction to the right). An elliptical ring-shaped third decorative line image (line pattern) inclined upward to the right by the line image (line pattern) (P2) and the line having the above-mentioned arrangement angle of 45° to the left (inclination direction to the left). Three of (P3) are displayed in a combined state.

In that case, as a precaution, the parallel lines of the colored underlayer (12) forming the first decorative line image (P1) of the second embodiment are the cyan line (12a) and the magenta line. (12b) and the yellow image line (12c), the lines of the colored underlayer (12) forming the second decorative line image (P2) are cyan image lines (12a). ) And a yellow image line (12c), which form the third decorative line image (P3), the colored underlayer (12) lines are magenta image line (12b) and yellow image line. (12c) and two colors.

As described above, the number of colored drawing lines forming a set in the colored underlayer (12) and the coloring colors combined with each other are different for each decorative line image (line pattern) (P1) (P2) (P3) (P4). It can be different.

Further, in the third embodiment of FIG. 9, the half-doughnut-shaped first decorative line image (the line pattern) is also formed by the line having the arrangement angle in the colored underlayer (12) that is 45 degrees to the right (inclination direction to the right). ) (P1) and the line with the arrangement angle of 45° to the left (inclining to the left), the second donut-shaped second decorative line image (line) facing the first decorative line image (P1). Pattern) (P2) and the parallel line having the arrangement angle of 0 degree (horizontal direction), and the circular third decorative line image (parallel line pattern) that becomes the background or ground pattern of the fourth decorative line image (P4). Four lines of (P3) and the fourth decorative line image (line pattern) (P4) of alphabet characters are displayed in a combined state by the line having the arrangement angle of 90 degrees (vertical direction).

That is, the plurality of decorative line images (P1) (P2) (P3) (P4) in the colored underlayer (12) are the marks composed of characters, figures, symbols, patterns, or a combination thereof, and the outline of the mark. Is separated by both ends of the parallel line, it is not necessary to trim the decorative line images (P1), (P2), (P3), and (P4), and the decorative line images (P1) and (P2) are not necessary. Even if the plurality of (P3) and (P4) become the pseudo hologram print (A) displayed in the overall combination state, the decorative line images (P1), (P2), (P3), and (P4) do not overlap each other. It is kept in print.

As a method for obtaining a plurality of distinguishable decorative line images (P1), (P2), (P3), and (P4), the array angle of the lines in the colored base layer (12) is different, but only that method is used. Similarly, the line width (thickness) (W1) of the lines in the colored underlayer (12) may be different, or the adjacent pitch (D1) between the lines may be different, or any one of them. The two methods may be combined and adopted.

Since the pseudo-hologram printed matter (A) according to the first embodiment of FIGS. 1 to 4 and the various partially modified embodiments of FIGS. 5 to 7 has the above configuration, a plurality of different parallel colored image lines (12a) are provided. ) (12b) (12c) 1 set (1 unit) consists of a line of colored underlayers (12) consisting of lines that are regularly spaced in parallel and spaced apart from each other, and a line with a line width (W2) wider than that line. When viewed through a transparent coating layer (13) having a plano-convex lens shape or a semi-cylindrical cross section, the refraction angle or reflection angle of light due to the plano-convex lens action of the transparent coating layer (13) varies depending on the viewing position and direction. The colored underlayer (12) of the decorative line image (P) is visible or invisible, and the visibility (shading) is also changed. The effect will be obtained.

In that case, the surface of the printing substrate (10) is exposed as an unprinted blank part (14) between the adjacent transparent coating layers (13) having a plano-convex lens shape or a semi-cylindrical cross section. As a plano-convex lens, the transparent coating layer (13) can be raised up high from the surface of the printing substrate (10), and the largest possible refraction of light causes various changes in the gloss and color tone. There is an effect that can be seen from a wide angle.

In particular, as in the pseudo-holographic prints (A) according to the second and third embodiments of FIGS. 8 and 9, the colored underlayer (12) covered with the transparent coating layer (13) has an arrangement angle and a line width. (W1) and/or a plurality of distinguishable decorative line images (P1) (P2) (P3) (P4) consisting of lines having different pitches (D1) adjacent to each other, if non-overprinting is performed. For example, as a pseudo hologram print (A) in which the plurality of decorative line images (P1), (P2), (P3), and (P4) are displayed in a composite state, the above-mentioned gloss and color tone have become more and more complex and diverse. And it is possible to obtain a high-quality visual effect.

In manufacturing the pseudo-holographic printed material (A) according to the first embodiment of FIGS. 1 to 4 and various partially modified embodiments of FIGS. 5 to 7, an inkjet printer (not shown) having a plurality of nozzles is used. Preferably, the following steps may be performed using a UV curable colored ink and a UV curable transparent varnish.

That is, a printing substrate (10) such as paper having a light reflecting layer (11) on the front surface as shown in FIG. 3, or a transparent plastic film having a light reflecting layer (11) on the back surface as shown in FIG. A printing substrate (10) such as (evaporated film) is prepared, and one set (1 unit) composed of a plurality of different parallel colored image lines (12a) (12b) (12c) as shown in FIGS. A line of lines that are regularly arranged in parallel at regular intervals (at regular intervals) is inkjet-printed on the surface of the printing substrate (10) with a UV-curable colored ink to form a colored line composed of the lines. The formation (12) is formed.

Then, one set (one unit) composed of a plurality of different parallel colored image lines (12a) (12b) (12c) in the colored underlayer (12) is covered from the front side as a whole (1 unit), as shown in FIGS. As described above, a line having a line width (W2) (thick) wider than the colored image lines (12a) (12b) (12c) of the colored underlayer (12) is formed into a plano-convex lens section with a UV curable transparent varnish. Alternatively, ink-jet printing is performed in the shape of a kamaboko.

In that case, the inkjet printer is provided with a plurality of nozzles (printer heads), and the colored ink and the transparent varnish are also UV-curable ones. And can be performed almost simultaneously at the same time, and the pseudo-holographic printed material (A) which is rich in gloss and color tone and rich in luxury can be efficiently mass-produced.

Furthermore, a plurality of different first to fourth decorative line images (line patterns) (P1) (P2) (P3) (P4) as shown in the second and third embodiments of FIGS. Also in the method of manufacturing the pseudo-holographic printed matter (A), the printing process of each of the decorative line images (line patterns) (P1) (P2) (P3) (P4) has been described based on the first embodiment. The colored base layer forming step and the transparent coating layer forming step may be performed in the same manner.

However, for example, in order to prevent the plurality of decorative line images (line patterns) (P1) (P2) (P3) (P4) from being overprinted, for example, the pseudo hologram print (A) according to the second embodiment of FIG. ), it is assumed that the first decorative line image (P1) is printed first, then, as shown in FIG. 10A, the subsequent second and third decorative line images (P2) (P3). The planned printing site of () is secured as a blank part (S).

After printing the first decorative line image (P1), the second and third decorative line images (P2) and (P3) are sequentially printed as shown in FIGS. The order of printing the plurality of decorative line images (P1) (P2) (P3) can be freely selected.

The pseudo hologram print (A) is peeled off by attaching, for example, a release sheet (not shown) to the back surface of the printing base material (10) to form a product package or business card. It can be provided as a product label or a decorative sticker to be attached.

The present invention relates to a product label, a decorative sticker, and other pseudo-hologram printed matter that can provide a variety of visual effects similar to holograms, and a manufacturing method effective for mass production thereof.

Pseudo-holographic prints and methods for manufacturing the same that are close to the present invention are disclosed in Patent Documents 1 and 2.

The printed matter described in Patent Document 1 is capable of transmitting light having a large number of convex portions (3A) or concave portions (3B) on its surface, and a transparent layer (3) composed of a transparent varnish, and A reflective layer (5) having a light reflecting surface (5A) provided on the back surface side of the transmissive layer (3) and a plurality of colored layers provided between the transmissive layer (3) and the reflective layer (5). The colored portion (7A) is provided between the colored layer (7) discretely arranged by printing and the transmission layer (3) and the reflective layer (5), and the thickness dimension of the colored colored portion (7A). (T2) has the same thickness dimension, and is provided with a colorless portion (9) printed with a medium (colorless transparent ink) between adjacent colored colored portions (7A), and the colorless portion ( 9) is the structure provided in the part corresponding to the recessed part (3B) of the said transmission layer (3).

On the other hand, the pseudo-holographic printed matter described in Patent Document 2 is a light reflection layer (2) on the surface of the printing object (10), and a colored ink layer printed with colored ink on the upper layer of the reflection layer (2). A pseudo-hologram print (1) comprising (3) and a pseudo-hologram layer (4) which is printed with a transparent ink in a predetermined range on an upper layer of the colored ink layer (3),

The pseudo hologram layer (4) has a plurality of matte transparent ink parts (41) for reducing the light reflectance of the colored ink layer (3) and a plurality of matte transparent ink portions (41) for increasing the light reflectance of the colored ink layer (3). At least any two or more of the glossy transparent ink portion (42) and the plurality of blank portions (43) on which the matte transparent ink and the glossy transparent ink are not printed are configured.

Japanese Patent No. 6271855 JP, 2017-71137, A

However, in the structure of the printed matter described in Patent Document 1, in addition to the fact that the light transmission layer (3) formed by printing with the transparent varnish always has the concave portion (3B) on its surface, the colored layer ( Since the colorless part (9) of 7) is printed with a medium (colorless transparent ink) in the same thickness dimension as the thickness dimension (T2) of the colored portion (7A), the light transmission layer (3) It is difficult to secure a large height difference between the convex portion (3A) and the concave portion (3B) in (4), and the light is merely scattered.

Further, there is no description that the convex portion (3A) of the transparent layer (3) is a line. Moreover, there is no explanation that the colored portion (7A) of the colored layer (7) is printed as a line consisting of colored image lines of different coloring colors.

Therefore, even if the colored portion (7A) of the colored layer (7) is printed in a striped pattern, if the parallel lines and the intersecting lines forming the striped pattern are in a thick solid printing state, complicated and various color tones are obtained. It is not possible to obtain a visual effect that is rich in a sense of change and is luxurious.

On the other hand, the pseudo-holographic printed matter described in Patent Document 2 has a blank portion (43) on which transparent ink is not printed, but has a matte transparent ink portion (41) and a glossy transparent ink portion (42) having different light reflectances. By arranging at least any two or more of the blank portion (43) and the colored ink layer (3), a three-dimensional illusion is given to the observer.

Therefore, when the colored ink of the colored ink layer (3) is a single color, the change of the color tone cannot be obtained even if the change of the shade is obtained, and much less the color ink of the colored ink layer (3) is used for printing. Since the image such as the designed pattern or characters is not divided and formed from the lines, it is impossible to obtain a pseudo-hologram printed matter rich in complex and various color changes and high quality.

Further, as a method for producing the printed matter, in addition to the colored ink printing step (S1), a matte transparent ink printing step (S2) and a glossy transparent ink printing step (S3) performed thereafter are necessary, and the matte transparent ink Both the transparent glossy ink and the glossy transparent ink must be printed so as not to overlap the character portion printed by the colored ink, which is very troublesome and cannot exert the mass production effect.
