Description

  In general, metal products have an appearance that gives a high-class feeling and a profound impression as compared to synthetic resin products and the like. For this reason, for example, many things such as symbol plates and character plates that are pasted to display various marks and names on the walls of buildings and various expensive products are made of metal such as aluminum or brass. Has been. Conventionally, in order to further enhance the high-class feeling and profound feeling of such a metal product, the surface of the metal product is cut (cut) by machining or the like and parallel to the surfaces. It is generally performed to form a hairline pattern in which a large number of straight lines, a large number of the same or similar curves are drawn, or a spin pattern (spindle pattern) in which a large number of concentric circles are drawn. Yes.

  On the other hand, a technique for forming a metal pseudo surface that represents a metal surface in a pseudo manner is known as one of screen printing application techniques that can be printed on a wide variety of substrates (substrates). This is a so-called metallic ink that has a metallic color (silver or gold) such as aluminum or brass on the front or back surface of a substrate made of a transparent resin flat plate made of polycarbonate or acrylic resin, or a transparent glass flat plate. A metallic ink layer (metal ground color layer) is formed by solid coating by printing, and the metal surface is expressed in a pseudo manner on the surface of the substrate on which the metallic ink layer is formed.

  And since the screen printed matter having a metal pseudo surface formed by such a screen printing technique is superior in formability, light weight and the like than a metal product, for example, the symbol plate and the character plate as described above. In addition, it is often used as a substitute for metal products for products that are preferably made of metal for obtaining a high-class feeling, profound feeling, and the like. In addition, recently, since a high-strength synthetic resin material is used as a base material, it is also applied to casings and the like of small and expensive electronic devices.

  In addition, a pattern similar to a hairline pattern or spin pattern formed on a metal surface by machining is applied to the metal pseudo surface of the screen so that a higher texture can be obtained on the metal pseudo surface of such a screen print. Some screen prints are formed by printing. For example, a screen printed matter formed by forming a metal ground color layer on one of the front surface and the back surface of the substrate and superposing a hairline pattern on the metal ground color layer ( For example, refer to Patent Document 1 below), a spin pattern is formed on both the front surface and the back surface of the substrate, and a metal ground color layer is formed on the spin pattern formed on the back surface. This is a screen print (see, for example, Patent Document 2 below).

  However, the inventors of the present invention have a conventional screen print in which a hairline pattern or spin pattern is formed on the surface by screen printing as described above, and a metal product having a surface in which the hairline pattern or spin pattern is actually formed by machining. When the surfaces of the conventional screen prints were compared, the hairline pattern and spin pattern on the surface of the conventional screen prints were clearly lacking in realism, and the conventional screen prints had a moire that caused appearance defects. Therefore, it has been found that it is extremely difficult to obtain a high-class feeling and heavy feeling that is exhibited in a metal product having a hairline pattern or a spin pattern machined on the surface, in a conventional screen print. It is.

  Here, the present invention has been made in the background as described above, and the problem to be solved is that the hairline pattern or spin pattern formed on the surface by machining is the surface by screen printing. Improvement of screen prints that are more realistically expressed without causing appearance defects due to moire by the hairline pattern or spin pattern formed on the screen, and that can provide a more luxurious and profound feeling more effectively. Is to provide an improved structure.

In addition, a pattern formed by screen printing using a light-transmitting ink, and a plurality of parallel straight lines extending continuously in one direction without any breaks have the same line width and constant pitch. And a first linear hairline pattern having a regular linear hairline pattern drawn with (c) an ink having light transparency so as to be superimposed on the first linear hairline pattern. The pattern is printed by screen printing, and both the line width and the pitch are different from the straight lines constituting the regular linear hairline pattern of the first linear hairline pattern. A plurality of straight lines including a line, or a straight line having one or a plurality of cuts and at least one of a line width and a pitch constituting the regular linear hairline pattern A screen print is characterized in that a plurality of parallel straight lines including different straight lines are provided with a second straight hairline pattern having an irregular straight hairline pattern drawn.

  In such a screen printed product according to the present invention, a plurality of parallel straight lines constituting the regular linear hairline pattern of the first linear hairline pattern and the second straight line on the printed surface of the substrate. Screen printing is performed in a state where a plurality of parallel straight lines constituting an irregular linear hairline pattern of the hairline pattern overlap each other with the latter as an upper side, or are adjacent to each other.

  Therefore, in such a screen-printed product, a larger number of straight lines on the printed surface of the substrate have no regularity, and are notable between straight lines that overlap one another and straight lines that do not overlap one another. As a result, the linear hairline pattern made up of a large number of straight lines can be drawn with a higher level of texture while eliminating or suppressing the occurrence of moiré more advantageously. Can be done.

  Therefore, in the screen printed material according to the present invention as described above, the linear hairline pattern formed on the surface by machining is a linear hairline pattern formed on the surface by screen printing, causing an appearance defect due to moire. And can be expressed more realistically. As a result, even if the base material is a metal product that has not been subjected to any surface processing or a screen printed matter having a metal pseudo surface, a linear hairline pattern is formed on the surface by machining. A high-class feeling and profound feeling comparable to that of metal products can be obtained even more effectively.

A light reflection layer that reflects the light irradiated from the printed surface side of the transparent sheet and emits a metallic luster is provided. Also according to this embodiment, for example, in a screen printed matter having a base material made of a synthetic resin or a glass transparent sheet, the metal pseudo surface does not cause an appearance defect due to moire or the like, and a more realistic texture and luxury. Can be effectively expressed.

<9> In any one of the above aspects <6> to <8>, the light reflecting layer directly or on the surface of the transparent sheet opposite to the surface to be printed Is formed on the light reflection layer, the ink reflection layer is formed on the entire surface of the light reflection layer by applying opaque ink over the entire surface of the light reflection layer. A light shielding layer is further provided which prevents light irradiated from the printed surface side of the sheet from passing through the light reflecting layer and increases the amount of light reflected by the light reflecting layer. According to this aspect, the light reflecting layer increases the reflected light in the light reflecting layer, so that the light reflecting layer emits a more vivid metallic luster and the metallic luster effect is exhibited at a higher level. Therefore, the metal surface cut by machining can be expressed with a more realistic texture.

  Hereinafter, in order to clarify the present invention more specifically, the configuration of a screen print according to the present invention will be described in detail with reference to the drawings.

  First, in FIG. 1 and FIG. 2, as an embodiment of a screen printed matter having a structure according to the present invention, a name plate which is a base plate of a predetermined emblem or mark is schematically shown in a planar form and a longitudinal sectional form, respectively. Is shown in As is clear from these drawings, the name plate 10 of the present embodiment has a printing sheet 12 as a base material, and a light reflection layer 14 on the surface (the upper surface of the printing sheet 12 in FIG. 2). On the other hand, the light shielding layer 16 is formed on the rear surface (the lower surface of the printing sheet 12 in FIG. 2).

  More specifically, the printing sheet 12 is configured by a transparent rectangular thin flat plate made of a resin material such as polycarbonate or acrylic resin, a glass material, or the like. And the light reflection layer 14 is formed on the surface of such a to-be-printed sheet 12 by apply | coating the ink which emits metallic luster by reflection of light to a circle by screen printing. In other words, the light reflecting layer 14 is an ink that is formed so as to completely cover a circular area portion of a predetermined size on the surface of the transparent printing sheet 12 with a predetermined thickness and emits a metallic luster due to reflection of light. It is composed of layers.

  On the other hand, the light shielding layer 16 is constituted by an opaque ink layer formed by applying opaque ink to the entire surface of the sheet 12 to be printed opposite to the light reflecting layer 14 formation side by solid screen printing. ing. In other words, the light shielding layer 16 is formed on the back side of the printing sheet 12 so as to cover the entire back surface of the light reflecting layer 14 via the printing sheet 12 with the light reflecting layer 14 being lined. Accordingly, light irradiated from the front surface side of the printing sheet 12 can be blocked from being transmitted through the light reflecting layer 14 and leaking from the back surface side of the printing sheet 12.

  Thus, here, the light irradiated from the surface side of the printing sheet 12 is reflected by the light reflection layer 14, and the light reflection layer 14 emits a metallic luster. In addition, since the light that has passed through the light reflecting layer 14 leaks from the back side of the printing sheet 12, the light shielding layer 16 blocks the amount of light reflected by the light reflecting layer 14. Effectively increased, the metallic luster can be emitted more clearly on the light reflecting layer 14. As a result, the formation site of the light reflection layer 14 on the surface of the printing sheet 12 is a metal pseudo surface portion 17 that artificially represents the metal surface with sufficient realism.

  As the ink for providing the light reflecting layer 14, among the screen inks used for screen printing, gold ink mixed with brass fine powder, silver ink mixed with aluminum fine powder, further red ink and gold ink. Ink that emits metallic luster such as gold, silver, bronze, etc. due to reflection of light, such as mixed ink that is a mixture of ink such as blue ink, candy ink, indigo ink, etc., is a metal color that should be expressed by the light reflecting layer 14 Depending on use, it is used appropriately. As the ink for providing the light shielding layer 16, an ink having an opaque color such as white or black is appropriately selected from various screen inks. Further, as the ink for providing the light reflecting layer 14 and the light shielding layer 16, generally an inexpensive solvent type is used, but the type (type) of such ink is not particularly limited.

Further, the thickness of the light reflecting layer 14 (dimension indicated by t ₁ in FIG. 2) and the thickness of the light shielding layer 16 (dimension indicated by t _{2 in} FIG. 2) are not limited at all. Although not provided, it is desirable that the thicknesses t ₁ and t ₂ of the light reflecting layer 14 and the light shielding layer 16 are 3 μm or more. As a result, leakage of transmitted light of the light reflecting layer 14 from the back side of the printing sheet 12 is further effectively prevented, and a more vivid metallic luster is emitted in the light reflecting layer 14. The upper limits of the thicknesses t ₁ and t ₂ of the light reflecting layer 14 and the light shielding layer 16 are appropriately set so that the light reflecting layer 14 and the light shielding layer 16 do not become unnecessarily thick due to wasteful use of ink. To be determined.

  In the name plate 10 of the present embodiment, in particular, the surface of the printing sheet 12 is a printing surface, and the light reflecting layer 14 that provides the metal pseudo surface portion 17 formed on the printing surface is provided. On top of that, a first spin pattern 18 and a second spin pattern 20 having different concentric circular patterns are laminated, and there are significant features not found in conventional products. .

  That is, as apparent from FIGS. 1 and 2 and FIG. 3 showing a planar form of a screen printed matter in which only the first spin pattern 18 is formed on the surface of the printing sheet 12, here, the printing sheet is here. A concentric pattern in which a large number of concentric circles are densely drawn is screen-printed using light-transmitting ink on substantially the entire circular region where the light reflecting layer 14 is formed on the surface of 12. The first spin pattern 18 is formed by the print pattern having the concentric pattern.

In other words, the first spin pattern 18 has a different diameter from each other, which is formed on substantially the whole of the circular metal pseudo-surface portion 17 in the printing sheet 12 by screen printing using light-transmitting ink. There are a number of first circular ridges 22 having no cuts, and a number of the first circular ridges 22 having different diameters from each other are set around the center point of the circular light reflecting layer 14 as O _1. Further, it is configured by being positioned so as to draw concentric circles.

Each of the multiple first circular ridges 22 having different diameters forming the first spin pattern 18 has the same width (dimension indicated by w _{1 in} FIG. 2), and extremely The first spin pattern 18 having such a large number of first circular ridges 22 has a narrow and constant pitch (the dimension indicated by P ₁ in FIG. 3). A concentric pattern is displayed.

  Further, as is apparent from FIGS. 1 and 2 and FIG. 4 showing a planar form of a screen printed matter in which only the second spin pattern 20 is formed on the surface of the printing sheet 12, the printing sheet 12 has On the first spin pattern 18 formed on the metal pseudo-surface portion 17, a second spin pattern 20 that exhibits a concentric pattern different from the first spin pattern 18 is formed on the entire surface. It is formed by screen printing using an ink having properties.

That is, the second spin pattern 20 has a plurality of second circular convex shapes 24 having different diameters formed by screen printing. Further, a large number of the second circular ridges 24 having different diameters are drawn so as to draw a concentric circle around the center: O ₂ of the reference circular ridge 24a having the smallest diameter among them. It is configured by being positioned.

Further, in such a large number of second circular ridges 24, the width (the dimension indicated by w _{2 in} FIG. 2) is the same as each first circular ridge in the first spin pattern 18. The width of the strip 22 is the same size as w ₁ , but the cuts 26 are formed in a non-uniform length at one or a plurality of randomly selected locations on the circumference of each strip. cage, also, (4, dimension indicated by P ₂₎ pitch, the pitch of the first circular projections 22: there is a non-uniform size different from the P _1. As a result, the second spin pattern 20 composed of a large number of second circular ridges 24 exhibits an irregular concentric pattern different from the first spin pattern 18 composed of a large number of first circular ridges 22. It has become.

As shown in FIG. 1, the center of the reference circular protrusion 24 a in the second spin pattern 20 having the irregular concentric pattern as described above: O ₂ , that is, a large number of second circular protrusions 24. In the radial direction of each first circular ridge 22 from the center: O _{1 in} the center: O ₁ in the first spin pattern 18 in which the center: O ₂ has a regular concentric pattern in FIG. The second spin pattern 20 is formed on the first spin pattern 18 so as to be superimposed on the right side of FIG. Although not shown in the figure, here, a predetermined emblem or mark is formed on the second spin pattern 20 formed on the first spin pattern 18 by using a predetermined screen ink. It is further formed by screen printing or the like.

  Thus, here, as shown in FIG. 1, a large number of first circular ridges 22 and a large number of second circular ridges 24 in a stacked state of the second spin pattern 20 on the first spin pattern 18. Are positioned so as to cross each other, overlap each other over a predetermined length, or are adjacent to each other in the radial direction. It is designed to change gradually in the direction. As a result, as shown in FIG. 2, the overlapping portions of the first circular ridges 22 and the second circular ridges 24 at the irregular positions on the metal pseudo-surface portion 17 have the highest height. The first circular ridge 22 is formed with a stepped portion 28 composed of the upper surface, and the second circular ridge 24 has a height lower than the overlapped portion. The second circular ridges 24 are formed so as to be positioned at random with a lower height than the second circular ridges 24.

As described above, in the present embodiment, the first spin pattern 18 and the second spin pattern 20 are stacked on the metal pseudo-surface portion 17 in a state where the centers: O ₁ and O ₂ are inconsistent. As a result, a larger number of circular ridges 22, 24 are formed without any regularity, and with a remarkable and complicated height difference.

  Therefore, in the name plate 10 of the present embodiment, the concentric patterns of the first spin pattern 18 and the second spin pattern 20 that are stacked by screen printing, that is, each spin pattern is a metal pseudo surface portion. The spin pattern formed by machining on the upper surface of the metal product in the metal pseudo-surface portion 17 can be formed on the metal pseudo surface portion 17 more sterically and without causing moire. It can be expressed more realistically without causing an appearance defect due to.

  Therefore, in the nameplate 10 according to this embodiment as described above, a high-class feeling and a solid feeling comparable to a metal product having a spin pattern formed on the surface by machining can be obtained extremely effectively. It is.

  In addition, as the ink for forming the first spin pattern 18 and the second spin pattern 20 as described above, among transparent screen inks used for screen printing, colorless transparent or colored ink having light transmittance is appropriately selected. Among them, among them, for example, an ultraviolet curable colorless transparent ink is preferably used. By using such an ink, it is possible to perform thick embossing printing peculiar to printing using an ultraviolet curable ink without impairing the vividness of the metallic luster emitted from the light reflecting layer 14. Both the first circular ridges 22 and the second circular ridges 24 of the second spin pattern 20 are advantageously thickened. As a result, the spin pattern in the first and second spin patterns 18 and 20 is sharpened, and the spin pattern formed by machining on the surface of the metal product in the metal pseudo-surface portion 17 is It can be expressed with a more realistic texture.

Further, the width of each first circular protrusion 22 of the first spin pattern 18 and each circular protrusion 24 of the second spin pattern 20, that is, the line width of the spin pattern in the first spin pattern 18: w ₁ The line width w ₂ of the spin pattern in the second spin pattern 20 is not particularly limited, but is about 0.2 to 0.5 point (0.07028 to 0.1757 mm). It is desirable that This is because it is difficult to print and form the respective spin patterns 18 and 20 having extremely small line widths: w ₁ and w ₂ below 0.2 point (0.07028 mm) with the current screen printing technology. In addition, when the line widths of the spin patterns 18 and 20: w ₁ and w ₂ exceed 0.5 points (0.1757 mm), the width of the circular ridges 22 and 24 becomes too large, Each of the spin patterns 18 formed densely by concentric circular ridges 22 and 24 having different diameters is formed on the metal pseudo-surface portion 17 in the same state as when light-transmitting ink is solidly applied. , 20 delicate spin patterns are not easily recognized.

Further, the pitch between the first circular ridges 22 of the first spin pattern 18: P ₁ , that is, the pitch of the concentric circles of the concentric pattern that gives the first spin pattern 18 is set to a constant value as described above. However, the value is selected within the range of 0.2 to 0.8 mm, for example. This is because it is difficult to print and form spin patterns 18 having such a pitch: P ₁ of less than 0.2 mm by screen printing, and when such pitch: P ₁ exceeds 0.8 mm, they are adjacent to each other. The gap between the first circular ridges 22 becomes excessive, whereby the first circular ridges 22 having different diameters draw concentric circles, and the spin pattern of the first spin pattern 18 is densely formed. This is because the texture is lowered.

The pitch P ₂ between the second circular ridges 24 of the second spin pattern 20, that is, the pitch of the concentric circles of the concentric pattern that gives the second spin pattern 20 is an uneven value as described above. However, the value is selected as a value within the range of 0.2 to 0.8 mm, for example, similarly to the pitch P ₁ between the first circular ridges 22 of the first spin pattern 18. . This is for the same reason as described above. A plurality of types of values are appropriately selected from the values within such a range.

Further, the thickness of each first circular ridge 22 of the first spin pattern 18 (the dimension indicated by t _{3 in} FIG. 2) and the thickness of each second circular ridge 24 of the second spin pattern 20. (Dimensions shown by t ₄ in FIG. 2) are also appropriately selected, but they are preferably 5 μm or more. This is because the spin patterns 18 and 20 whose thicknesses: t ₃ and t ₄ are less than 5 μm are too thin and the sharpness of the spin pattern is impaired. Further, the upper limit values of the thickness: t ₃ of each first circular ridge 22 of the first spin pattern 18 and the thickness: t ₄ of each second circular ridge 24 of the second spin pattern 20 are: Although none of them is specified, the patterns 18 and 20 are appropriately determined as long as the patterns 18 and 20 do not become unnecessarily thick due to waste of ink. Further, the thickness t ₄ of each second circular ridge 24 of the second spin pattern 20 is made larger than the thickness t ₃ of each first circular ridge 22 of the first spin pattern 18. It is desirable that

  Furthermore, the length of the cuts 26 formed at one place or a plurality of places on the circumference of each second circular ridge 24 in the second spin pattern 20 is not particularly limited, for example, a metal pseudo surface portion. 17, the length of the cut 26 is about 0.1 to 30 mm, although it is determined as appropriate depending on the size of the formation region of the second spin pattern 20 on the surface 17. preferable. This is because if the length of the cut 26 is less than 0.1 mm, the cut 26 is too short, and the presence of the cut 26 and the first and second circular ridges 22 and 24 obtained thereby. This is because the complicated height difference cannot be fully recognized. In addition, when the length of the cut line 26 exceeds 30 mm, the cut line 26 is too long, making it difficult to give a delicate spin pattern to the second spin pattern 20. This is because there is a risk that the effect of expressing the spin pattern is significantly reduced.

By the way, in the first embodiment, each second circular ridge 24 of the second spin pattern 20 has the same width as the width: w ₁ of each first circular ridge 22 in the first spin pattern 18: w ₂ , a cut 26 provided with a non-uniform length at one or a plurality of positions on the circumference, and a non-uniform pitch: P ₂ . as indicated, a number of second circular projections 24, the width of the first spin pattern 18 in each first round projections 22: w ₁ and nonuniform widths including those of different sizes are: w ₂ And a cut 26 provided with a non-uniform length at one or a plurality of locations on the circumference, and a constant pitch: P ₂ that is the same as the pitch: P _{1 of} each first circular ridge 22. And the second spin pattern 20 is constituted by such a large number of second circular ridges 24. And it may be. The second spin pattern 20 as described above is also formed so as to be superimposed on the first spin pattern 18 formed on the metal pseudo-surface portion 17 as in the first embodiment. Therefore, it is possible to effectively enjoy various actions and effects.

Further, for example, as shown in FIG. 6, a large number of second circular ridges 24 include those having a size different from the width: w ₁ of each first circular ridge 22 in the first spin pattern 18. It is configured to have a non-uniform width: w ₂ and a pitch of each first circular ridge 22: a non-uniform pitch: P ₂ including a size different from P ₁ , and such The second spin pattern 20 may be configured by a large number of second circular ridges 24.

Furthermore, for example, as shown in FIG. 7, a large number of second circular ridges 24 have the same width: w _{2 as} the width: w ₁ of each first circular ridge 22 in the first spin pattern 18. a cut 26 provided in a non-uniform length in one place or a plurality of locations on the circumference, the pitch of the first circular projections 22: P ₁ and the same constant pitch: P _2, or such a pitch: P ₁ and Has a non-uniform pitch including different sizes: P ₂ , and among the many second circular ridges 24, the center of each second circular ridge 24 excluding the reference circular ridge 24 a is The center of the reference circular ridge 24a is configured to be positioned at a position different from O _2, and the second spin pattern 20 is configured by such a large number of second circular ridges 24. May be.

Furthermore, for example, as shown in FIG. 8, a large number of second circular ridges 24 having a size different from the width: w ₁ of each first circular ridge 22 in the first spin pattern 18. Including non-uniform width: w ₂ and pitch of each first circular ridge 22: constant pitch: P ₂ same as P ₁ , or non-uniform pitch including pitch different from P ₁ : : and a P _2, and a number of the second circular projections 24, the centers of the second circular projections 24 except the reference circular ridge 24a is, the reference circular ridges 24a center: O ₂ a The second spin pattern 20 may be configured by a plurality of second circular ridges 24 configured to be positioned at different positions. In addition, although not shown, it is of course possible to provide cuts 26 having a non-uniform length with respect to a large number of second circular ridges 24 in the second spin pattern 20.

  Then, the second spin pattern 20 having the structure shown in FIGS. 6 to 8 is formed so as to overlap the first spin pattern 18 formed on the metal pseudo-surface portion 17. As a result, the same actions and effects as those of the first embodiment can be enjoyed effectively.

Incidentally, in the first embodiment, the reference circular ridges 24a in the second spin pattern 20 center: O ₂ is the center of a number of first circular projections 22 in the first spin pattern 18: from O ₁ The second spin pattern 20 was laminated on the first spin pattern 18 in a state of being offset by a predetermined dimension on the right side in FIG. 1 in the radial direction. The positional deviation direction between the second spin pattern 20 and the first spin pattern 18 is not limited to this as long as it is the radial direction of the first circular ridge 22. It is of course possible to form the second spin pattern 20 on the first spin pattern 18 without any misalignment.

  In the first embodiment, the light reflection layer 14 is formed on the front surface of the printing sheet 12 and the light shielding layer 16 is formed on the back surface thereof. On top of this, the light reflecting layer 14 and the light shielding layer 16 are laminated so that the latter is positioned on the printed sheet 12 side, or the light reflecting layer 14 and the light shielding layer 16 are formed on the back surface of the printed sheet 12. Alternatively, the former may be laminated so that the former is positioned on the printed sheet 12 side.

  Furthermore, if only the light reflection layer 14 can reflect the irradiation light from the surface side of the printing sheet 12 in a sufficient amount, the light shielding layer 16 is not necessarily provided.

  Furthermore, the region where the light reflecting layer 14 and the light shielding layer 16 are formed on the printing sheet 12, that is, the overall shape of the light reflecting layer 14 and the light shielding layer 16 is not limited to the illustrated circular shape. However, other shapes can be employed as appropriate, and the formation region of the first spin pattern 18 and the second spin pattern 20 on the surface of the printing sheet 12 is also on the surface of the printing sheet 12. According to the formation region of the light reflection layer 14 in FIG.

  Next, FIG. 9 schematically shows another embodiment of a screen print having a structure according to the invention in its planar form. As is apparent from FIG. 9, the screen print 30 of the present embodiment has a metal plate 32 made of a rectangular metal plate such as aluminum, for example, as a base material. Then, one surface in the thickness direction of the metal plate 32 is used as a printing surface 34, and the first linear hairline pattern 36 and the second linear shape are formed on substantially the entire surface excluding the outer peripheral portion of the printing surface 34. A hairline pattern 38 is formed in a stacked manner.

  More specifically, as is clear from FIG. 9 and FIG. 10 showing a planar form of a screen printed matter in which only the first linear hairline pattern 36 is formed on the printing surface 34 of the metal plate 32, here, as shown in FIG. A linear hairline pattern in which a number of straight lines parallel to each other are densely drawn on the entire rectangular area excluding the outer peripheral portion on the printing surface 34 is screen-printed using light-transmitting ink. The first linear hairline pattern 36 is formed by the printing pattern that exhibits this linear hairline pattern.

That is, the first linear hairline pattern 36 is formed by a large number of unbroken first linear shapes formed on substantially the entire printed surface 34 of the metal plate 32 by screen printing using light-transmitting ink. The ridge 40 is provided. The first linear-shaped projections 40 a number of them, the same length and width with each other, very narrow, (10, dimension indicated by P ₃₎ constant pitch with a and, the metal plate 32 It is configured by being positioned on the printing surface 34 so as to extend parallel to each other continuously in the left-right direction in FIG. Thus, the first linear hairline pattern 36 has a regular linear hairline pattern.

  Further, as is clear from FIG. 9 and FIG. 11 showing a planar form of a screen printed matter in which only the second linear hairline pattern 38 is formed on the printing surface 34 of the metal plate 32, On the first linear hairline pattern 36 formed on the printing surface 34, a second linear hairline that exhibits a linear hairline pattern different from the first linear hairline pattern 36 on the whole. The pattern 38 is formed by screen printing using an ink having optical transparency.

  That is, the second linear hairline pattern 38 has a large number of second linear protrusions 42 formed by screen printing using light-transmitting ink. And these many 2nd linear protruding item | line 42 is comprised by being located on the to-be-printed surface 34 of the metal plate 32 so that it may extend in parallel with each other continuously in the left-right direction in FIG. Yes.

Furthermore, in such a large number of second linear ridges 42, the width thereof is the same as the width of each first linear ridge 40 in the first linear hairline pattern 36. However, the cuts 44 are formed at non-uniform lengths at one or a plurality of points selected at random in the length direction of each, and the pitch (P _{4 in} FIG. 11) is formed. size) indicated by the well, the pitch of the first straight-shaped projections 40: there is a non-uniform sizes, including those of different sizes and P _3. As a result, the second linear hairline pattern 38 composed of a large number of second linear ridges 42 is different from the first linear hairline pattern 36 composed of a large number of first linear ridges 40. It is designed to have a hairline pattern.

  Then, as shown in FIG. 9, the second linear hairline pattern 38 having the irregular linear hairline pattern as described above is the first linear hairline pattern 36 having the regular linear hairline pattern. It is formed so as to overlap.

  Thus, here, a large number of first straight ridges 40 and a large number of second straight ridges 42 under the laminated state of the second linear hairline pattern 38 on the first linear hairline pattern 36. However, some of them are positioned so as to overlap with each other over the entire length or to be adjacent to each other in the width direction. It is supposed to be uniform. As a result, overlapping portions of the first straight ridges 40 and the second straight ridges 42 are formed at the highest height at irregular positions on the printing surface 34 of the metal plate 32. In addition, the second straight ridge 42 has a lower height than the overlapped portion, and the first straight ridge 40 has a height lower than the second straight ridge 42, respectively. It is formed so as to be located at random. Furthermore, although not clearly shown in FIG. 9, the formation portion of the cut 44 of the second linear ridge 42 in the overlapping portion of the first linear ridge 40 and the second linear ridge 42 is not provided. The step part which consists of the upper surface of the 1st linear protruding item | line 40 is formed.

  Thus, in the present embodiment, the first linear hairline pattern 36 and the second linear hairline pattern 38 are laminated and formed on the printing surface 34 of the metal plate 32 so as to overlap each other. Thus, more linear ridges 40 and 42 are formed without any regularity, and with a remarkable and complicated height difference.

  Therefore, in the screen print 30 of the present embodiment, the linear hairline patterns of the first linear hairline pattern 36 and the second linear hairline pattern 38 that are laminated by screen printing are formed on the metal plate 32. It can be formed on the printing surface 34 with a higher texture without being more three-dimensional and causing moire.

  Therefore, in the screen printed matter 30 according to the present embodiment as described above, the printing surface 34 of the metal plate 32 is not machined at all, but the printing surface 34 is machined. The formed linear hairline pattern can be expressed more realistically without causing appearance defects due to moire. And as a result, there is no need for a large and expensive equipment for machining the linear hairline pattern on the surface, and a luxury feeling comparable to a metal product on which the linear hairline pattern is formed on the surface by machining. A profound feeling can be obtained very effectively.

  The ink that forms the first linear hairline pattern 36 and the second linear hairline pattern 38 as described above is formed on the metal pseudo surface portion 17 of the name plate 10 according to the first embodiment. The same ink as that for forming the first spin pattern 18 and the second spin pattern 20 is used. Further, the width, pitch, thickness, length of the cut line 44, etc. of the first and second linear ridges 40, 42 constituting the first and second linear hairline patterns 36, 38 are, for example, The first and second circular ridges 22 and 24 constituting the first and second spin patterns 18 and 20 have the same width, pitch, thickness, length of the cut line 26, and the like.

By the way, in said 2nd embodiment, each 2nd linear protrusion 42 of the 2nd linear hairline pattern 38 is the same as the width | variety of each 1st linear protrusion 40 in the 1st linear hairline pattern 36. 12, the slits 44 having a non-uniform length provided at one or a plurality of locations in the length direction, and a non-uniform pitch: P ₄ . As shown in FIG. 3, the multiple second linear ridges 42 have non-uniform widths including those having a size different from the width of each first linear ridge 40 in the first linear hairline pattern 36. , a cut 44 provided in one place or a plurality of locations uneven length in the lengthwise direction, of the first straight-shaped projections 40 pitch P ₃ with the same constant pitch so as to have a P ₄ And a second straight line with a number of such second straight ridges 42 It is also possible to configure the hairline pattern 38. The second linear hairline pattern 38 as described above is also formed so as to overlap the first linear hairline pattern 36 formed on the printing surface 34 of the metal plate 32. The same operations and effects as those of the second embodiment can be enjoyed effectively.

Further, for example, as shown in FIG. 13, a large number of second linear ridges 42 having a size different from the width of each first linear ridge 40 in the first linear hairline pattern 36. And having a non-uniform width including each of the first straight ridges 40 and a non-uniform pitch including P ₄ having a size different from that of P ₃ , and such a large number You may make it comprise the 2nd linear hairline pattern 38 with the said 2nd linear protrusion 42. FIG.

Furthermore, for example, as shown in FIG. 14, each second linear ridge 42 of the second linear hairline pattern 38 has a width of each first linear ridge 40 in the first linear hairline pattern 36. A non-uniform width including those of different sizes, a cut 44 provided with a non-uniform length in one or more locations in the length direction, and the pitch of each first straight ridge 40: P ₃ having a non-uniform pitch including a size different from ₃ : P ₄ , and with such a large number of second linear ridges 42, a second linear hairline pattern 38. You may make it comprise.

  Then, the second linear hairline pattern 38 having the structure shown in FIGS. 13 and 14 is superimposed on the first linear hairline pattern 36 formed on the printing surface 34 of the metal plate 32. Even if formed in this way, the same actions and effects as in the second embodiment can be enjoyed effectively.

  Next, FIG. 15 schematically shows yet another embodiment of a screen print having a structure according to the invention in its planar form. As is apparent from FIG. 15, the screen printed product 46 of this embodiment has a metal plate 48 made of a rectangular plate made of metal such as aluminum as a base material. Then, one surface in the thickness direction of the metal plate 48 is set as a printing surface 50, and the first curved hairline pattern 52 and the second curved shape are formed on substantially the entire surface excluding the outer peripheral portion of the printing surface 50. The hairline pattern 54 is laminated.

  More specifically, as is apparent from FIG. 15 and FIG. 16 showing a planar form of a screen printed matter in which only the first curvilinear hairline pattern 52 is formed on the printing surface 50 of the metal plate 48, as shown in FIG. Then, a curvilinear hairline pattern in which a large number of corrugated curves are densely drawn on the entire rectangular area excluding the outer peripheral portion on the printing surface 50 is screen-printed using light-transmitting ink. And the 1st curvilinear hairline pattern 52 is formed with the printing pattern which exhibits this curvilinear hairline pattern.

That is, the first curvilinear hairline pattern 52 is formed in substantially the same wave shape with no cuts formed on substantially the entire printed surface 50 of the metal plate 48 by screen printing using light-transmitting ink. A plurality of first curved ridges 56 exhibiting The first song linear projections 56 a number of them, and same width, very narrow, (16, dimension indicated by P ₅₎ constant pitch with a a, the printed surface 50 of the metal plate 48 It is configured by being positioned so as to extend continuously in the left-right direction in FIG. Thus, the first curved hairline pattern 52 has a regular curved hairline pattern. Note that the first curved ridge 56 formed on the upper and lower portions of the printing surface 50 of the metal plate 48 in FIGS. 15 and 16 is a portion positioned at the center of the printing surface 50. It should be understood that the first curved ridges 56 formed in a part are formed of a part of the same shape.

  Further, as apparent from FIG. 15 and FIG. 17 showing a planar form of a screen printed matter in which only the second curved hairline pattern 54 is formed on the printing surface 50 of the metal plate 48, On the first curvilinear hairline pattern 52 formed on the printing surface 50, a second curvilinear hairline that exhibits a curvilinear hairline pattern different from the first curvilinear hairline pattern 52 as a whole. The pattern 54 is formed by screen printing using light-transmitting ink.

  That is, the second curved hairline pattern 54 has a plurality of second curved ridges 58 that are formed by screen printing using light-transmitting ink and have the same wave shape. . And these many 2nd curve-shaped convex stripes 58 are comprised by being located on the to-be-printed surface 50 of the metal plate 48 so that it may extend continuously in the left-right direction in FIG.

Further, in such a large number of second curved ridges 58, the width is the same as the width of each first curved ridge 56 in the first curved hairline pattern 52. However, the cuts 60 are formed in a non-uniform length at one or a plurality of locations selected at random in the length direction of each of the components, and the pitch (in FIG. 17, P ₆ dimension indicated by) also, the pitch of the first song linear projections 56: there is a non-uniform sizes, including those of different sizes and P _5. As a result, the second curved hairline pattern 54 composed of a large number of second curved ridges 58 is different from the first curved hairline pattern 52 composed of a large number of first curved ridges 56. A hairline pattern is presented. Furthermore, here, among the many second curved ridges 58 in the second curved hairline pattern 54, the one located at the approximate center in the vertical direction in FIG. 17 is defined as the reference curved ridge 58a. Yes.

Then, as shown in Figure 15, the predetermined curvature circle of the second curved hairline reference in the pattern 54 curvilinear ridges 58a having an irregular curved hairline pattern, such as the center: O ₃ is, rules Curvature of the first curved ridge 56a closest to the reference curved ridge 58a among the many first curved ridges 56 in the first curved hairline pattern 52 having a typical curved hairline pattern. The second curvilinear hairline pattern 54 is located on the left side of FIG. 15 in the radial direction from the center of the circle: O ₄ , with the second curvilinear hairline pattern 54 being offset by the dimension indicated by n. The hairline pattern 52 is formed so as to overlap.

  Thus, here, a number of first curve-shaped ridges 56 and a number of second curve-shaped ridges 58 under the stacked state of the second curve-shaped hairline pattern 54 on the first curve-shaped hairline pattern 52 Are crossed with each other, overlapped over a predetermined length, or positioned adjacent to each other in the radial direction of each curvature circle, and the interval between those adjacent to each other is, They are non-uniform with each other and gradually change. As a result, overlapping portions of the first curved ridges 56 and the second curved ridges 58 are formed at the highest height at irregular positions on the printing surface 50 of the metal plate 48. In addition, the second curved ridge 58 has a lower height than the superposed portion, and the first curved ridge 56 has a lower height than the second curved ridge 58, respectively. It is formed so as to be located at random. Furthermore, although not clearly shown in FIG. 15, there is an area where the cut line 60 of the second curved ridge 58 is formed in the overlapping portion of the first curved ridge 56 and the second curved ridge 58. The step part which consists of the upper surface of the 1st curve-shaped protruding item | line 56 is formed.

  Thus, in the present embodiment, the first curved hairline pattern 52 and the second curved hairline pattern 54 are laminated and formed on the printing surface 50 of the metal plate 48 so as to overlap each other. Thus, more curved ridges 56 and 58 are formed without any regularity and with a remarkable and complicated height difference.

  Therefore, in the screen printed matter 46 of the present embodiment, the curved hairline patterns of the first curved hairline pattern 52 and the second curved hairline pattern 54 that are formed by screen printing are formed on the metal plate 48. It can be formed on the printing surface 50 with a higher texture without being more three-dimensional and causing moire.

  Therefore, in the screen printed matter 46 according to the present embodiment as described above, the printing surface 50 of the metal plate 48 is not machined at all, but the printing surface 50 is subjected to machining. The formed curly hairline pattern can be expressed more realistically without causing appearance defects due to moire. And as a result, without requiring any large and expensive equipment for machining the curved hairline pattern on the surface, a high-class feeling comparable to a metal product having a curved hairline pattern formed on the surface by machining. A profound feeling can be obtained very effectively.

  The ink that forms the first curvilinear hairline pattern 52 and the second curvilinear hairline pattern 54 as described above is formed on the metal pseudo surface portion 17 of the name plate 10 according to the first embodiment. The same ink as that for forming the first spin pattern 18 and the second spin pattern 20 is used. In addition, the width and pitch, thickness of each of the first and second curved ridges 56, 58 constituting the first and second curved hairline patterns 52, 54, the length of the cut line 60, etc., for example, The first and second circular ridges 22 and 24 constituting the first and second spin patterns 18 and 20 have the same width, pitch, thickness, length of the cut line 26, and the like.

By the way, in said 3rd embodiment, each 2nd curvilinear protruding line | wire 58 of the 2nd curvilinear hairline pattern 54 is the same as the width | variety of each 1st curvilinear protrusion 56 in the 1st curvilinear hairline pattern 52. , A cut 60 provided with a non-uniform length at one or a plurality of positions in the length direction, and a non-uniform pitch: P ₆ , for example, FIG.

The second curvilinear hairline pattern 54 as described above is also formed so as to overlap the first curvilinear hairline pattern 52 formed on the printing surface 50 of the metal plate 48. The same actions and effects as those of the third embodiment can be enjoyed effectively.

Further, for example, as shown in FIG. 19, a large number of second curved ridges 58 have a size different from the width of each first curved ridge 56 in the first curved hairline pattern 52. And having a non-uniform width including each of the first curved ridges 56 and a non-uniform pitch including P ₆ having a size different from that of P ₅ , and such a large number The second curved hairline pattern 54 may be configured by the second curved ridges 58.

Furthermore, for example, as shown in FIG. 20, each second curved ridge 58 of the second curved hairline pattern 54 is the width of each first curved ridge 56 in the first curved hairline pattern 52. A non-uniform width including a different size, a cut 60 provided with a non-uniform length in one or more locations in the length direction, and the pitch of each first curved ridge 56: P ₅ with a non-uniform pitch including P ₆ , and with such a large number of second curved ridges 58, the second curved hairline pattern 54. You may make it comprise.

  Then, the second curved hairline pattern 54 having the structure as shown in FIGS. 19 and 20 is superimposed on the first curved hairline pattern 52 formed on the printing surface 50 of the metal plate 48. Even if formed in this way, the same operations and effects as those of the third embodiment can be enjoyed effectively.

In the third embodiment, the center of the predetermined curvature circle of the reference curved ridge 58a in the second curved hairline pattern 54: O ₃ is a number of first curves in the first curved hairline pattern 52. of curvilinear projections 56, the curvature of the circle of the first song linear projections 56a that is closest to the reference curve shaped projections 58a center: from O _4, by a predetermined distance on the left side of FIG. 15 in the radial direction biasing The second curved hairline pattern 54 is laminated on the first curved hairline pattern 52 in a state where the second curved hairline pattern 54 and the second curved hairline pattern 54 are arranged. The positional deviation direction of one curved hairline pattern 52 is not limited as long as it is the radial direction of the curvature circle of the first curved ridge 56a. Further, the second curvilinear hairline pattern 54 may be laminated on the first curvilinear hairline pattern 52 without such positional deviation.

  In the third embodiment, the first curved hairline pattern 52 is composed of a plurality of first curved ridges 56 having the same shape, and the second curved hairline pattern 54 is also mutually connected. For example, as shown in FIG. 21 to FIG. 23, the first curved hairline pattern 62 has a similar shape to each other. The second curvilinear hairline pattern 64 can also be composed of a plurality of second curved ridges 68 that have similar shapes to each other.

In the present embodiment, the width of each second curved ridge 68 constituting the second curved hairline pattern 64 is equal to the width of each first curved ridge 66 in the first curved hairline pattern 62. However, the cut line 70 is formed in a non-uniform length at one or a plurality of points selected at random in the length direction of each second curved ridge 68. in addition, (23, dimension indicated by P ₈₎ the pitch of each of the second tracks the linear projections 68 also in pitch (Figure 22 of the first song linear projections 66, indicated by P ₇ dimensions ) has been non-uniform size, including those having a size different from, such second width curved hairline pattern 64 each second song linear ridge 68 which constitute the or pitch of P ₈ Regarding the size, the presence or absence of the cut 70, etc., the third Embodiment similar variations (e.g., variations shown in FIGS. 18 to 20) from among, are properly selected.

<Example 1>
First, a printing sheet made of a transparent rectangular flat plate having a thickness of 0.5 mm, which is made of polycarbonate and has a smooth surface and a back surface, was prepared as a base material. Then, a screen ink [trade name: MRC750 Silver (manufactured by Mino Group Co., Ltd.)] that emits a silver metallic luster by reflection of light on a circular region of a predetermined size on the surface of the prepared printing sheet is 250 mesh. Using this screen, a solid coating was applied by a known screen printing technique, and this was dried and cured to form a light reflecting layer having a thickness of 2 μm.

  Next, an opaque screen ink having a black color [trade name: MRC black (manufactured by Mino Group)] is applied to the entire back surface of the printing sheet using a 250 mesh screen by a known screen printing method. This was dried and cured to form a light-shielding layer having a thickness of 2 μm.

  Thereafter, a transparent ultraviolet curable screen ink [trade name: 6100SL medium (manufactured by Jujo Chemical Co., Ltd.)] is applied to the entire surface of the light reflection layer of the printing sheet using a 350 mesh screen. A large number of first circular ridges as shown in FIG. 3 having the same width but different diameters were printed by a printing method so as to draw concentric circles at a constant pitch. Then, the first spin pattern having a concentric pattern is cured by irradiating the multiple first circular ridges with ultraviolet rays with an ultraviolet irradiator, thereby curing the multiple first circular ridges. Formed. The line width of the first spin pattern thus formed, that is, the width of each first circular protrusion was set to 0.15 points (0.05271 mm), and the thickness was set to 10 μm.

  Subsequently, on the first spin pattern formed on the surface of the sheet to be printed, the same ink as the ink that gives the first spin pattern is formed by a known screen printing method as shown in FIG. The first spin pattern has the same width as each of the first circular ridges, but the pitch is different, and one or more cuts in the length direction are provided with non-uniform length cuts. A large number of second circular ridges were formed by printing. In addition, as shown in FIG. 1, such a large number of second circular ridges have their center points from the central points of the many first circular ridges in the first spin pattern. It was designed to be offset by 0.2 mm in the radial direction of the strip. In addition, the length of the cut formed in each of these many second circular ridges is set to a non-uniform length within a range of 0.1 to 30 mm, and the pitch of each second circular ridge is set to 0. Within the range of 3 to 2.0 mm, the pitch was different from the pitch of the first circular ridges. Furthermore, the thickness of each 2nd circular protruding item | line was 10 micrometers.

  After that, as described above, the second circular ridges are irradiated with ultraviolet rays with an ultraviolet irradiator on the multiple second circular ridges laminated on the first spin pattern. Was cured. Thus, the second spin pattern having an irregular concentric pattern was formed so as to be superimposed on the first spin pattern having a regular concentric pattern. In forming the second spin pattern, a 350 mesh screen was used.

  Thus, the light reflecting layer and the light shielding layer are respectively formed on the surface and the back surface of the printing sheet, and the metal pseudo surface is formed on the surface of the printing sheet. A target screen printed matter in which the spin pattern and the second spin pattern were integrally laminated was obtained.

  Then, when the obtained screen printed matter was visually observed from the surface, a silver metallic luster was emitted by reflection of light on the surface, and the surface producing such metallic luster was formed on the upper surface of the metal product. Similar to the spin pattern formed by machining, it is recognized that a spin pattern having a more three-dimensional and high texture is formed, and further, such a surface has a moire pattern that does not appear on the actual metal surface. It was confirmed that almost no generation occurred. For this reason, in the screen printed matter having the structure according to the present invention, the metal surface cut by machining without causing any deterioration in appearance due to the occurrence of moire has a higher texture, and is even more realistic and at a lower cost. It can be clearly recognized that it can be expressed as:

<Example 2>
First, as a base material, a metal plate made of a rectangular flat plate having a thickness of 0.5 mm and made of aluminum and having a smooth surface and a back surface was prepared. Then, the surface of the prepared metal plate is substantially the same as each other by a known screen printing method using a transparent ultraviolet curable screen ink [trade name: 6100SL medium (manufactured by Jujo Chemical Co., Ltd.)]. A plurality of first straight ridges having a width and a length, as shown in FIG. 10, are printed at a constant pitch so as to extend parallel to each other, and the first The linear ridges were irradiated with ultraviolet rays with an ultraviolet irradiator and cured to form a first linear hairline pattern having a linear hairline pattern. The line width of the first spin pattern thus formed, that is, the width of each first linear protrusion was set to 0.25 points (0.08785 mm), and the thickness was set to 10 μm.

  Next, on the first linear hairline pattern formed on the surface of the metal plate, the same ink as the ink that gives the first linear hairline pattern is used, and a known screen printing technique is used as shown in FIG. The configuration as shown, i.e., the width of each first linear protrusion in the first linear hairline pattern is the same, but the pitch is different, and it is uneven at one or more locations in the length direction. A number of second straight ridges were formed by printing with length cuts. In addition, the length of the cut formed in each of these many second straight ridges is set to a non-uniform length within a range of 0.1 to 30 mm, and the pitch of each second straight ridge is In the range of 0.3 to 3.0 mm, the pitch is different from the pitch of the first linear ridges. Furthermore, the thickness of each second linear protrusion was 10 μm.

  And after that, as described above, the second linear ridges laminated on the first linear hairline pattern are irradiated with ultraviolet rays with an ultraviolet irradiator. The straight ridges were cured. Thus, the second linear hairline pattern having an irregular linear hairline pattern was formed so as to be superimposed on the first linear hairline pattern exhibiting the regular linear hairline pattern. In forming the first linear hairline pattern and the second linear hairline pattern, a 350 mesh screen was used.

  Thus, the intended screen printed material was obtained, in which the first linear hairline pattern and the second linear hairline pattern were integrally laminated on the surface of the metal plate.

  Then, when the obtained screen printed matter was visually observed from the surface, a linear shape having a more three-dimensional and high texture, like the linear hairline pattern formed by machining on the upper surface of the metal product, on the surface. It was confirmed that a hairline pattern was formed, and it was further confirmed that almost no moire that caused an appearance defect occurred on the surface. From this, in the screen printed matter having a structure according to the present invention using a metal plate as a substrate, the metal surface cut by machining without causing any deterioration in appearance due to the occurrence of moire has a higher texture, It can be clearly recognized that it can be expressed even more realistically and at a lower cost.
