Description

    The present invention relates to a three-dimensional printed material that allows a design portion to be viewed three-dimensionally by providing a light reflecting layer on an opening design portion such as characters and symbols provided on a ground color layer.

    As a conventional three-dimensional printed material, for example, the one described in Patent Document 1 below is known.

Japanese Patent Laying-Open No. 2007-38551 (FIG. 2)

  This is a three-dimensional printed material including a transparent base material and a print display portion having a predetermined shape formed by screen printing on the back surface of the base material, and the print display portion is provided on the back surface of the base material. A first ink portion having an edge forming an outer shape of the first ink portion and a second ink portion that contacts the edge and forms a border of the print display portion are printed by screen printing, and the second ink portion transmits light. A third ink part is formed by screen printing, which is formed of a possible ink and is thicker than the first ink part, and further covers the second ink part and fills between the edges of the second ink part. The third ink portion is formed of mirror surface ink.

  In such a three-dimensional printed material, since the second ink part is provided so as to contact the edge part of the first ink part, the second ink part is composed of the mirror surface ink filled between the edges of the second ink part. The three ink parts are visually recognized as popping out from the first ink part, and a three-dimensional effect is expressed.

    However, in such a conventional three-dimensional printed material, since the first ink portion occupying most of the three-dimensional printed portion is composed of a single color ink, the feeling received from the entire three-dimensional printed material becomes monotonous, There was a problem that the decoration effect and the design effect were not sufficient.

  An object of this invention is to provide the three-dimensional printed matter which can improve a decoration effect and a design effect easily.

    The object is to provide a transparent base material, a pattern layer that is formed of a large number of linear protrusions printed with light transmissive ink on the back surface of the base material, and presents a predetermined pattern, and the pattern Printed on the back side of the base material so as to cover the layer, and printed with a ground color layer having an open design part, and ink that allows light to pass through the side edge of the design part, and is in close contact with the side edge This is achieved by a three-dimensional printed material provided with a border layer and a light reflecting layer made of a light reflecting material provided on the back side of the substrate so as to cover both the back surface and the border layer of the substrate overlapping the design portion. be able to.

  In this invention, the back surface of the base material is provided with a pattern layer that is formed of a large number of linear protrusions printed with light transmissive ink, and reveals a predetermined pattern, and the pattern layer is opened. Since it is covered with a ground color layer having a portion, a predetermined pattern can be superimposed on the ground color to give the viewer a fresh feeling. Thereby, the decoration effect and design effect of a three-dimensional printed matter improve easily.

  Moreover, if comprised as described in Claim 2, while blocking | transmitting permeation | transmission of the light from a back surface side to the surface and ensuring clear visual recognition of a design part, peeling of a ground color layer, a border layer, and a light reflection layer Etc. can be prevented. Furthermore, if it comprises as described in Claim 3, the light reflection layer in a design part can be protruded enough and reliably from a ground color layer.

It is a top view which shows Embodiment 1 of this invention. It is II sectional view taken on the line of FIG. It is the A section enlarged view of FIG.

Embodiment 1 of the present invention will be described below with reference to the drawings.
In FIGS. 1, 2, and 3, reference numeral 11 denotes a plate-like or sheet-like substrate. The substrate 11 is made of, for example, plastic such as polycarbonate, acrylic, polyethylene, or polyester, or glass. Here, the base material 11 is transparent, and may be colored as long as the design portion of the ground color layer to be described later can be clearly seen from the surface 11a side.

  14 is a pattern layer provided in close contact with the back surface 11b of the substrate 11, and this pattern layer 14 is provided on a part or the whole of the back surface 11b, in this embodiment, except for the design portion described later, circular, Various shapes such as rhombus and rectangle can be used. The pattern layer 14 may be provided in the design portion. Here, the pattern layer 14 includes a plurality of linear protrusions 15 that are substantially parallel to each other, and these linear protrusions 15 are directly printed on the back surface 11b of the substrate 11 by, for example, screen printing. The linear protrusions 15 are made of ink that can transmit light, that is, highly transparent. However, the linear protrusions 15 may be colored so as not to affect the light transmittance.

  An example of such ink that can transmit light is an ultraviolet curable clear ink. When this ink is used, it can be cured by irradiating with ultraviolet rays after printing on the substrate 11. Good. And when this pattern layer 14 is seen from the surface 11a side, it can reveal a predetermined pattern. In this embodiment, the pattern layer 14 is spaced equiangularly in the circumferential direction with the center point S being the substantially center of the substrate 11. Recognized as a plurality of linearly extending radial lines L.

  Here, in order to make the above-described pattern appear, the back surface 11b is divided into a plurality of fan-shaped areas with the radial line L centered on the center point S as a dividing line, and a large number of arc-shaped areas are formed in each fan-shaped area. However, the center of curvature of these linear protrusions 15 is located between the position where the linear protrusions 15 are provided and the center point S, and away from the center point S. The radius of curvature increases as the linear protrusion 15 increases. Furthermore, both ends of the linear protrusion 15 provided in each fan-shaped area are continuous with one end of the linear protrusion 15 in the adjacent fan-shaped area. As a result, the continuous linear protrusion 15 has a shape like a round circle. Thus, a large number of these round-shaped linear protrusions 15 are arranged concentrically while being slightly separated from each other in the radial direction with the center point S as the center. If such a linear protrusion 15 is arranged on the back surface 11b, it is recognized as a radiation pattern in which the dividing line of the fan-shaped region is the radial line L.

  The predetermined pattern on which the pattern layer 14 appears is not limited to that of this embodiment, and there are various other forms. For example, a plurality of substantially sector-shaped partitioned areas are arranged in a zigzag shape on the back surface 11b while being in contact with each other along a straight line, and the partitioned areas arranged in this zigzag shape are also orthogonal to the straight line. Further, a large number of arcuate linear protrusions 15 that are arranged repeatedly and extend almost in parallel in each of the above-described partition regions are provided by printing. In this case, the outer shape of the substantially sector-shaped partition area is clearly visually recognized, and these partition areas are recognized as a pattern repeatedly arranged in the XY directions.

  18 is a ground color layer provided by, for example, screen printing on the back surface side of the base material 11. The ground color layer 18 covers the entire pattern layer 14, and in this embodiment, the ground color layer 18 is provided on the entire base material 11. ing. The ground color layer 18 can be a color ink containing an organic pigment or an inorganic pigment, a mica alone or a pearl ink containing a pearl pigment formed by coating titanium oxide or iron oxide on a mica, and the like. 11 may be divided into a plurality of regions, and the ground color layer 18 may be provided by printing with different inks in each region.

  Then, by providing the ground color layer 18 so as to cover the pattern layer 14 in this way, the pattern layer 14 is recognized as a predetermined pattern provided on the ground color layer 18 from the surface 11a side. In addition, the ground color layer 18 is formed with an opening (a white window penetrating in the thickness direction) such as a design portion 19 such as letters, numbers, symbols, figures, and patterns to be viewed by the viewer. Since the linear protrusion 15 is not provided on the back surface 11b of the portion overlapping the design portion 19, as described above, the flat back surface 11b is exposed.

  As described above, the pattern layer 14 is provided on the back surface 11b of the base material 11 and includes a plurality of linear protrusions 15 and presents a predetermined pattern, and the ground layer 18 having the design portion 19 opened. Since a predetermined pattern overlaps the ground color, a fresh feeling can be given to the viewer. Thereby, the decoration effect and design effect of a three-dimensional printed matter can be improved easily.

  Reference numeral 22 denotes a border layer formed by printing, for example, by screen printing over the entire side edge 19a of the design portion 19 of the ground color layer 18, and this border layer 22 is a light-emitting layer. Can be formed with a medium ink that can transmit, and a highly transparent UV curable clear ink. The border layer 22 may be lightly colored as long as it can transmit light. The border layer 22 has an L-shaped cross section, and is bent and extends so that the side separated from the base material 11 is separated from the design portion 19. When the rim layer 22 has such a cross-sectional shape, light transmission, reflection, and refraction are complicated, and the light reflection layer, which will be described later, is visually recognized as popping out from the ground color layer 18, that is, toward the surface 11a side. A three-dimensional feeling is expressed.

  In this embodiment, the thickness of the border layer 22 and the thickness of the ground color layer 18 are the same, but the thickness of the border layer 22 is thicker than the ground color layer 18, and the base layer 11 of the border layer 22 is The separated side may protrude from the back surface of the ground color layer 18 by a predetermined amount. Here, the width W orthogonal to the thickness direction of the border layer 22 is preferably in the range of 0.01 to 0.10 mm. The reason for this is that if the width W is less than 0.01 mm, the light reflection layer cannot sufficiently be recognized from the ground color layer 18, while if it exceeds 0.10 mm, the light reflection layer and the ground color layer 18 This is because the boundary of the image becomes unclear and the feeling of popping out becomes unstable.

  25 is the back surface 11b (exposed surface of the back surface 11b) of the portion of the base material 11 that overlaps the design portion 19, and the back surface side of the base material 11 so as to cover both the side edge and the back surface of the border layer 22, for example by screen printing. The light reflection layer 25 is provided, and the light reflection layer 25 is formed of a metallic ink or a mirror ink having high light reflectivity including a metal powder pigment such as aluminum powder or bronze powder. As the light reflecting layer 25, a light reflecting material may be used. In addition to the ink as described above, a metal deposited film on which a metal is deposited, a metal foil, or the like may be used. As described above, since the narrow border layer 22 is interposed between the light reflection layer 25 and the ground color layer 18, the light reflection layer 25 in the design portion 19 is located in front of the ground color layer 18 as described above. It is visible as if it jumped out.

  28 is a shielding layer provided by, for example, screen printing on the back surface side of the base material 11 so as to cover the ground color layer 18 and the light reflection layer 25, and this shielding layer 28 is formed from an opaque ink having a high light shielding property. Yes. Here, the color of the opaque ink may be a chromatic color, but an achromatic color such as white or gray is preferable because it does not adversely affect the color of the ground color layer 18. If such a shielding layer 28 is provided, light transmission from the back surface side to the surface 11a can be blocked to ensure a clear visual recognition of the design portion 19, and the ground color layer 18 and the border layer 22 In addition, peeling of the light reflecting layer 25 can be prevented. The shielding layer 28 can be omitted as necessary. Such a three-dimensional printed material can be used for various seals, stickers, and the like in addition to the members constituting the outer shell parts of various devices, the exterior plate, the face plate, and the like.

Next, the operation of the first embodiment will be described.
When manufacturing the three-dimensional printed material as described above, first, a large number of substantially parallel linear protrusions 15 are formed on the back surface 11b of the base material 11 by screen printing, gravure printing, or the like using an ink capable of transmitting light. Direct printing is performed to form a pattern layer 14 that is in close contact with the back surface 11 b of the substrate 11. Next, printing is performed by screen printing, gravure printing or the like using the ink as described above on the back surface side of the base material 11 to cover the pattern layer 14 and form a ground color layer 18 having an open design portion 19. . By covering the pattern layer 14 that reveals the predetermined pattern with the ground color layer 18 in this way, the predetermined pattern overlaps the ground color and can give a fresh feeling to the viewer. The decorative effect and design effect can be easily improved.

  Next, printing is performed on the side end 19a of the design portion 19 by screen printing or the like using an ink that can transmit light, and the border layer 22 that is in close contact with the side end 19a is formed. Thereafter, a light reflecting layer 25 is formed on the back surface 11b of the portion overlapping the design portion 19 and the side edges and back surface of the border layer 22 by screen printing or the like using a highly light reflective ink. As a result, the narrow border layer 22 is interposed between the light reflecting layer 25 and the ground color layer 18 so that the light reflecting layer 25 in the design portion 19 is visually recognized to jump out from the ground color layer 18. Next, a shielding layer 28 that covers the ground color layer 18 and the light reflection layer 25 is formed on the back surface 11b side of the base material 11 by screen printing, gravure printing, or the like using an ink having a high light shielding property, thereby producing a three-dimensional printed material.

  The present invention can be applied to the industrial field of a three-dimensional printed material that allows a design portion provided in a ground color layer to be viewed three-dimensionally.
