Description

  The present invention is used for an instrument such as an automobile, and in particular, a hairline display of an instrument panel that expresses a hairline pattern on the surface (a pattern that appears to have been finished by applying numerous scratches to a metal material). Concerning structure.

  Conventional instrument panels are widely used in which a metallic ground color layer is formed by solid-printing metallic ink on a substrate such as a plastic plate, and a metal finish pattern is printed on the metal ground color layer with smoke ink or the like. ing. In this metal finishing, a hairline pattern similar to that formed on the processed surface can be expressed on the substrate by machining the metal plate with an inexpensive method.

  However, in such a conventional instrument panel, since the printed layer and the metal finish pattern are one layer, the design of the hairline pattern and the satin pattern is monotonous and lacks realism to the extent that it cannot be compared with the machined hairline pattern. There was an inconvenience.

  On the other hand, for example, Patent Document 1 discloses a display board in which realism is imparted to a hairline pattern by printing. As shown in FIGS. 5 and 6, the first smoke-like paint is printed on the substrate 1, the metal ground color layer 2 formed on the surface side of the substrate 1, and the upper surface of the metal ground color layer 2. The first design layer 3 formed of the first processed pattern 31 formed, and the second design layer formed of the second processed pattern 41 formed by printing the second smoke-like paint on the upper surface of the first design layer 3. 4 is a display board A. The first processed pattern 31 and the second processed pattern 41 have substantially the same shape, and the second design layer 4 includes the second processed pattern 41 and the first processed pattern 31 so that they intersect each other. In this configuration, the processed pattern 41 is applied in a state where the processed pattern 41 is moved with respect to the first processed pattern 31 of the first design layer 3. A region where the metal ground color layer 2, the first design layer 3, and the second design layer 4 are not provided is a display unit 5 such as numerals and scales.

  Therefore, in this display board A, the design layer for applying the processed pattern 31, 41 is provided with two layers of the first design layer 3 and the second design layer 4, and the second processed pattern 41 and the first processed layer. When the tone pattern 31 intersects, the shading by the processed tone patterns 31 and 41 becomes complicated. In particular, in the vicinity of the intersection of the second processed pattern 41 and the first processed pattern 31, the pattern density increases as the point approaches the intersection, and the pattern density decreases in a portion away from the intersection. Therefore, on the surface of the display board, the shading distribution of the processed patterns 31 and 41 is not uniform but non-uniform. For this reason, the appearance of the display board A is as if it were a real metal processing pattern.

  Moreover, as shown in FIG. 7, the transparent substrate 1A, the first hairline 6 provided by printing on the surface side of the substrate 1A, and the first hairline 6 by printing on the back side of the substrate 1A. A corresponding second hairline 7, a ground color layer 9 provided on the back side of the second hairline 7 except for a portion that becomes the display unit 8, and a light shielding layer that covers the ground color layer 9 Patent Document 2 discloses a display panel B having 10 and a white transmissive display layer 11 that covers a portion corresponding to the display unit 8 on the back side of the substrate 5. The first hairline 6 and the second hairline 7 are formed by printing innumerable colorless and transparent ink, for example, by straight lines extending radially from the center of the substrate 1A, or by concentric circles having the center of the substrate 1A as the origin. .

  As described above, the first hairline 6 and the second hairline 7 are provided by printing on the front surface side and the back surface side of the transparent substrate 1A, and the ground color layer 9 is provided so as to overlap the second hairline 7, so that it is inexpensive. A fine hairline can be expressed by the method, and a three-dimensional feeling can be given to the hairline. Further, by making the ground color layer 9 metallic, a metallic decorative member with a hairline with a fine and three-dimensional effect can be obtained.

  Further, as shown in FIG. 8, the resin substrate 12, the colored design layer 13 formed on the upper surface (lower surface), and the surface of the resin substrate 12 opposite to the design surface on which the design layer 13 is formed. The concavo-convex layer 14 formed by alternately arranging a plurality of concave portions 14a and convex portions 14b is formed, and the concavo-convex layer 14 is UV-cured so that the thickness of the convex portions 14b is larger than the thickness of the concave portions 14a. Japanese Patent Application Laid-Open No. H10-228688 discloses a display panel C in which droplets of a conductive ink are printed and cured by ink jet printing. The design layer 13 has a three-layer structure including a metal coloring layer 16, a black coloring layer 17, and a white printing layer 18 in a region excluding the display unit 15.

  In this display panel C, a transparent concavo-convex layer 14 is formed on the surface opposite to the design surface side, and the concavo-convex layer 14 has a plurality of concave portions 14a and a plurality of convex portions 14b arranged alternately and concentrically. Thus, the concentric pattern of the concavo-convex layer 14 causes interference fringes, and allows the driver or the like to observe the gloss and texture of the metal based on the metal coloring layer 16 on the design surface side. .

  Further, as shown in FIG. 9, a light reflecting layer 20 that emits a metallic luster by reflection of light is formed by screen printing on the back surface of the printing sheet 19 made of a transparent flat plate, while the light reflection on the printing sheet 19 is performed. On the surface opposite to the layer 20, there are a concentric spindle pattern 21 in which a large number of concentric circles are drawn with circular ridges 21 a at a constant pitch, and a radial pattern that extends radially from the central portion of the spindle pattern 21. Patent Document 4 discloses an instrument panel D in which a radial pattern 22 is laminated and formed by screen printing using light-transmitting ink. Here, the spindle pattern 21 and the radial pattern 22 are formed by screen-printing light transmissive ink. Further, a light shielding layer 23 is provided on the back surface of the light reflecting layer 20.

  In this instrument panel D, since a metallic luster is emitted from the light reflecting layer 20 formed on the back surface of the printing sheet 19, the surface of the light reflecting layer 20 on the printing sheet 19 side functions as a mirror surface, thereby A spindle pattern 21 formed on the surface of the printing sheet 19 using light-transmitting ink is projected onto the light reflection layer 20 and formed on both the front and back surfaces of the printing sheet 19. It will be in such a state. For this reason, in such an instrument panel D, it is apparent between the spindle pattern 21 actually formed on the surface of the printing sheet 19 and the spindle pattern projected on the light reflection layer 20 on the back surface of the printing sheet 19. The spin effect in which reflected light is rotated and the reflected light appears to be rotated is effectively exhibited. Therefore, such a spin effect and the metallic luster effect generated in the light reflecting layer 20 are combined to perform machining. The hairline pattern similar to the metal surface cut by the above is realistically expressed with high texture on the surface of the printing sheet 19.

  However, each of the display boards described in Patent Documents 1 to 4 uses a metallic print layer as a base, and prints a hairline with transparent or light-transmitting ink thereon, or prints a hairline with thick ink. However, it is possible to obtain a glossy change and texture in the hairline, but because only the transparent ink or thick ink is used to print the hairline, the glossiness of the hairline There was an inconvenience that it was not possible to give a sufficiently strong impression to the change in feeling and the texture of the hairline. In addition, in any of the conventional display panels, there is an inconvenience that only a slight hairline is drawn on the metal plate, and it is difficult to visually recognize the hairline when viewed away from the printing surface. .

  On the other hand, by mixing the part where only the solid printing part is printed with metallic ink and the part where the solid printing part and the hairline pattern printing part overlap in two layers, the color density of the two parts is mixed. Patent Document 5 discloses an expression structure of a metallic surface capable of emphasizing metallic irregularities (shadows).

However, the conventional metal surface representation structure described in Patent Document 5 described above has the following problems to be solved.
That is, since the printing of the solid printing portion and the pattern printing portion is performed with the same color (or the same type) metallic ink, the density of the color development is not sufficiently emphasized, and the unevenness is an unevenness generated by two printings. The degree of shading enhancement is small, and the hairline cannot be sufficiently visually recognized (identified) from a position away from the printing surface.

  The present invention has been made in view of the above-described circumstances, and its purpose is to enhance the impression of the hairline while highlighting the change in glossiness by making the appearance of the metallic tone of the two layers different, Accordingly, it is an object of the present invention to provide a hairline display structure of an instrument panel that can recognize hairlines remarkably even from a position away from the printing surface.

In order to achieve the above-described object, the hairline display structure of the instrument panel according to the present invention is characterized by the following (1) to (4).

According to the hairline display structure of the instrument panel configured as described in (2) above, a portion of the first metallic tone printed layer on the front surface of the substrate that can be directly viewed by a portion that is not covered by the smoke printed layer and the second metallic tone printed layer And a portion that can be seen through the smoke printed layer, the appearance of the first metallic print layer is different, and a change in glossiness can be felt on the viewer side as a hairline. At the same time, due to the difference in appearance between the second metallic tone printed layer and the first metallic tone printed layer arranged with a level difference from the second metallic tone printed layer, the difference in the glossiness of the hairline in this portion is caused. It becomes even more prominent. Therefore, the change in the glossiness of the hairline is further emphasized, and this hairline pattern can be easily visually recognized even from a position away from the instrument panel.

At the same time, due to the difference in appearance between the second metallic tone printed layer and the first metallic tone printed layer arranged with a level difference from the second metallic tone printed layer, the difference in the glossiness of the hairline in this portion is caused. It becomes even more prominent. Therefore, the change in the glossiness of the hairline is further emphasized, and this hairline pattern can be easily visually recognized even from a position away from the instrument panel.
According to the configuration of the above (4), the glossiness of the hairline changes more delicately, and the impression of the hairline can be further effectively enhanced. Further, even from a position away from the printing surface, it can be recognized in the same manner as when the hairline is viewed close.

  According to the present invention, by changing the appearance of the two layers of the first metallic tone printed layer and the second metallic tone printed layer from the front of the instrument panel, the glossiness and texture of each hairline can be changed.

  Hereinafter, a hairline display structure of an instrument panel according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

  The hairline display structure of the instrument panel of the present embodiment shown in FIG. 1 includes a substrate 51, a light shielding layer 52, a first metallic print layer 53, a smoke printed layer 54, and a second metallic print layer 55. Have

  The substrate 51 is made of a printing material such as a plastic plate or a glass plate whose front and back surfaces are formed smoothly. The substrate 51 is provided with display portions (not shown) for numbers, scales, characters, and the like indicating the speed of the vehicle, and the first metallic tone printed layer 53, the smoke printed layer 54, and the second are formed at portions other than these. The metallic print layer 55 is provided.

  The light shielding layer 52 is a printing layer made of black ink or the like, and blocks light incident from the back side of the substrate 51. For example, a light source for displaying scales or numbers on the back side of the substrate is installed. In addition, it functions to prevent the upper first metal-tone printed layer 53 from being transparently exposed to the surface side by turning on the light source.

  The first metallic tone printed layer 53 is formed of a metallic ink printed layer using a pearl pigment made by coating metal powder such as aluminum powder or bronze powder or mica with titanium oxide or iron oxide. Accordingly, the first metallic tone printed layer 53 reveals a metal color such as gold, silver, pearl, or the like. The first metallic print layer 53 is printed via a light shielding layer 52 on a substrate 51 in a portion excluding a display portion for numbers, scales, characters and the like indicating the speed of the vehicle.

  The smoke print layer 54 is printed on the first metal tone print layer 53 with a width wider than that of a second metal tone print layer 55 described later in detail. As the smoke printing layer 54, for example, a clear coating material in which gloss and transparency are increased by kneading medium and black ink, or a mat coating material in which gloss is suppressed by mixing a matting agent and black ink or the like is used.

  The second metallic print layer 55 is printed on the smoke print layer 54. The second metallic tone printed layer 55 is sufficiently narrower than the width of the smoke printed layer 54. Therefore, when the smoke printed layer 54 is viewed from above, the second printed metallic layer 55 The metal-like print layer 55 protrudes greatly on both sides.

  Therefore, the instrument panel of the present embodiment has a light shielding layer (omitted if necessary) 52, a first metallic print layer 53, a smoke printed layer 54, and a second metallic print layer 55 on a transparent substrate 51. Are printed in this order. In the instrument panel obtained in this printing process, the first metallic tone printed layer 53 is directly observed between the adjacent smoke printed layers 54, and the smoke printing is performed. There arises a portion where the first metallic print layer 53 is indirectly seen through the layer 54. Therefore, in addition to the difference in the appearance of the two portions of the first metallic tone printing layer 53, the presence of the second metallic tone printing layer 55 extends in the longitudinal direction of the metallic tone printing layers 53, 55. While realizing a hairline pattern, the change (difference) in the glossiness of these two metallic print layers 53 and 55 can be made noticeable on the viewer side.

  Further, the first metal tone print layer 53 and the second metal tone print layer 55 are different in height in the stacking direction by the thickness of the smoke print layer 54. Due to the difference in height, a difference in appearance between the first metallic tone printed layer 53 and the second metallic tone printed layer 55, which are directly visible portions, occurs. You can feel it. Therefore, the change in glossiness is more emphasized compared to the conventional one that expresses the hairline using a metallic print layer and non-metallic transparent ink or thick ink, and for those who observe the instrument panel, The hairline can be clearly impressed.

  In addition, with the configuration using the first metallic tone printing layer 53 and the second metallic tone printing layer 55, one of the printing layers constituting the hairline is not a metallic tone printing layer, for example, a conventional transparent or smoke ink. Compared with the printed layer using, the hairline is greatly emphasized. Therefore, the hairline can be clearly recognized even when viewed from a position away from these printing surfaces. When the instrument panel is a disk, the first metal tone print layer 53 and the second metal tone print layer 55 have a plurality of concentric circles whose hairline pattern is, for example, centered on one point. Formed as.

  As described above, according to the hairline display structure of the instrument panel of the present embodiment, the first metallic tone printed layer 53 on the substrate 51 is covered with the smoke printed layer 54 and the second metallic tone printed layer 55. The portion that can be seen directly and the portion that can be seen through the smoke printed layer 54 are different, so that the appearance of the first metal-like printed layer 53 is different, and the side that sees the change (difference) in glossiness as a hairline Make you feel. At the same time, due to the difference in appearance between the second metallic tone printed layer 55 and the first metallic tone printed layer 53 in which the smoke printed layer 54 is separated in level, the difference in the glossiness of the hairline in this portion becomes more prominent. . Therefore, the change in glossiness of each hairline is further emphasized, so that the hairline pattern can be easily viewed from a position away from the instrument panel or the like.

  FIG. 2 shows another embodiment of the present invention. In this embodiment, a transparent plate is used as the substrate 51A, the same first metallic tone print layer 53 as described above is printed on the back surface side of the substrate 51A, and the back surface (lower surface) of the first metallic tone print layer 53 is further printed. ) Side is printed with a light shielding layer 52 of black ink. Further, a plurality of smoke print layers 54 having a predetermined width are printed on the surface side of the substrate 51A, and a second metallic tone print layer having a width narrower than that of the smoke print layer 54 is formed on the smoke print layers 54. 55 is printed in the same manner as in the case shown in FIG.

  In this embodiment, the first metallic print layer 53 is printed on the back surface of the substrate 51A. However, since the substrate 51A is a transparent plate, the transparent substrate 51a is transmitted from the front of the instrument panel. The first metallic print layer 53 on the back of this can be seen. Therefore, similar to the above-described embodiment, due to the difference in appearance between the first metallic tone printed layer 53 seen through the substrate 51A and the second metallic tone printed layer 55 seen directly, these Differences in the glossiness and texture of the hairline between the viewers can be viewed from a position away from the display surface.

  By the way, in the instrument panel shown in FIG. 1, the width of the printing layer constituting the second metallic tone printing layer 55 can be changed according to a desired hairline pattern, for example, as shown in FIG. In this case, the change in the glossiness and texture of the hairline is further emphasized, and the adjacent ones of the second metallic tone printed layer 55 are brought closer to or away from each other, thereby enhancing the impression of the hairline. Such a hairline configuration can also be adopted for an instrument panel as shown in FIG.

  Further, by performing dot printing on the smoke print layer 54 and the second metallic tone print layer 55, the density of each print layer can be arbitrarily adjusted. FIG. 4 is an explanatory diagram illustrating a situation in which the area surrounded by IV in FIG. 1 can be adjusted by dot printing. In FIG. 4, the smoke print layer 54 includes a dense region (a range indicated by “dark”) where the density of dots printed is high, and a sparse region (“light”) where the arrangement density of dots printed is low. The range shown). The higher the dot density, the darker the color, and the lower the dot density, the lighter the color appears. The second metallic print layer 55 is also dot-printed on the smoke print layer 54. Similar to the smoke print layer 54, the second metallic tone print layer 55 can change the density by adjusting the dot density. Such dots are formed along the hairline direction. Thereby, the glossiness and texture change of the hairline are further emphasized, and the impression of the hairline can be strengthened even when viewed from a position away from the printing surface.

  Note that the printing method according to the present embodiment is effective not only for the hairline but also for printing that expresses a line by some kind of printing on the metal-like print layer, and is effective for expressing the metal. By printing, high quality printing can be performed.

  As described above, according to the hairline display structure of the instrument panel of the present embodiment, the portion of the first metal tone print layer 53 on the substrate 51A that is not covered by the smoke print layer 54 and the second metal tone print layer 55 is displayed. Since there are a portion that can be seen directly through the transparent substrate 51A and a portion that can be seen through the smoke printed layer 54, the appearance of the first metallic print layer 53 is different, and the change in glossiness is seen as a hairline. You can feel it. Further, the difference in appearance of the second metallic tone printed layer 55, the smoke printed layer 54, and the first metallic tone printed layer 53 separated from the level difference of the substrate 51A may cause a difference in glossiness of the hairline in this portion. Furthermore, it becomes easy to visually recognize each hairline pattern even from a position away from the instrument panel.

  Moreover, the hairline display structure of the instrument panel according to the present embodiment has a configuration in which the line widths of the smoke printed layer 54 and the second metallic tone printed layer 55 change in the longitudinal direction thereof, so that the glossiness of the hairline is further increased. It will change subtly and the impression of the hairline can be further enhanced.
