Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drawing structures, and in particular to a drawing structure capable of displaying different degrees of metallic luster. BACKGROUND

[0002] In recent years, the fineness of artworks has gradually been valued. In order to be able to present metallic luster, these metallic lusters can generally be realized by forming a lamination in the drawing structure, for example, gold stamping can be provided on the color ink. However, the metallic luster presented by this method is single, and it is difficult to meet the needs of users for color images.

[0003] In other words, although the drawing structure has gradually met their purposes, there are still some problems to be overcome. Therefore, how to provide a drawing structure capable of displaying different degrees of metallic luster has become a topic to be solved in the art. CONTENT OF THE INVENTION

[0004] The embodiment of the present application provides a drawing structure to solve the problem that the metallic luster presented by the drawing structure in the prior art is single and it is difficult to meet the needs of users for color images.

[0005] In order to solve the above technical problems, the present application is implemented as follows:

[0006] In some embodiments, a drawing structure is provided, which includes a metal foil, a shading ink layer and a color ink layer. The shading ink layer is provided on the metal foil, wherein the shading ink layer includes a first part and a second part, and the first shielding rate of the first part is different from the second shielding rate of the second part. The color ink layer is provided on the shading ink layer.

[0007] In some embodiments, the metal foil is a silver foil.

[0008] In some embodiments, the shading ink layer is white ink.

[0009] In some embodiments, the first shielding rate of the first part of the shading ink layer and the second shielding rate of the second part of the shading ink layer are both greater than 0%.

[0010] In some embodiments, the periphery of the shading ink layer has a gradually decreasing thickness.

[0011] In some embodiments, the width of the first part or the second part of the shading ink layer is between 0.1 mm and 1000 mm.

[0012] In some embodiments, the color ink layer is provided on the shading ink layer and the metal foil in a blanket manner.

[0013] In some embodiments, in a top view, the total area of the color ink layer is greater than the total area of the light-shielding ink layer.

[0014] In some embodiments, the color ink layer includes a third portion, the third portion corresponding to the first portion and covering the first portion.

[0015] In some embodiments, the color ink layer further includes a fourth portion, the fourth portion corresponding to the second portion and covering the second portion.

[0016] As mentioned above, the present application provides a drawing structure, which is provided with a light-shielding ink layer between a color ink layer and a metal foil. By controlling various parameters of the light-shielding ink layer, the color image can present multiple metal luster, thereby meeting the needs of users. In order to make the features and advantages of the present application more obvious and easy to understand, various embodiments are described below, and the drawings are described in detail as follows. BRIEF DESCRIPTION OF DRAWINGS

[0017] The drawings described herein are used to provide further understanding of the present application, and form a part of the present application.

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] In the drawing structure, color ink can be disposed on the drawing paper by printing, inkjet, etc. to form a color image. Further, to make the color image have more abundant and diverse display effects, more layers of drawing structure can be formed. For example, a layer of gold material can be disposed on the color ink by screen printing, lithography or gilding, etc. to make the color image have metallic luster. However, it is difficult to present gold color with different hues, levels and brightness on a single color image by this way, and there is a problem of inaccurate overprint. In addition, by disposing silver ink on the color ink to present metallic luster, there is a problem of insufficient brightness of metallic luster and the color is not gold (it is gray). Similarly, the technology of attaching gold foil by glue also has the problems of insufficient resolution (i.e. insufficient precision) and difficulty in presenting different levels and brightness of gold color.

[0024] Therefore, the present application provides a drawing structure, which is provided with a light-shielding ink layer between the color ink layer and the metal foil. By controlling the parameters of the light-shielding ink layer, the color image can present diverse metallic luster to meet the needs of users.

[0025] Reference Figures 1 to 4 , wherein Figures 1 to 4 is a cross-sectional schematic view of a drawing structure according to some embodiments of the present application. In some embodiments, Figures 1 to 4 may be a cross-sectional schematic view of different positions of a single drawing structure 1, but the present application is not limited thereto. In other embodiments, Figures 1 to 4 may also be a cross-sectional schematic view of different drawing structures 1.

[0026] As shown in Figure 1 , the drawing structure 1 includes a metal foil 10, a light-shielding ink layer 12 and a color ink layer 14. It is worth mentioning that, for the sake of simplicity, Figure 1 (and Figures 2 to 4 ) omit some possible elements or components. In other embodiments, those skilled in the art can set other elements or components such as adhesives between the above-mentioned elements according to needs.

[0027] As shown in Figure 1As shown, the metal foil 10 can serve as a substrate to support the light-shielding ink layer 12 and the colored ink layer 14 disposed thereon. In addition, the metal foil 10 can also be used to form various colors with a metallic luster together with the colored ink layer 14. For example, when the colored ink layer 14 above the metal foil 10 is yellow, light from the external environment, after passing through the colored ink layer 14 and being reflected by the metal foil 10, will appear as a metallic yellow (or gold). Alternatively, when the colored ink layer 14 above the metal foil 10 is green, light from the external environment, after passing through the colored ink layer 14 and being reflected by the metal foil 10, will appear as a metallic green. In other words, this application can form various colors with a metallic luster through the light mixing between the metal foil 10 and the colored ink layer 14.

[0028] like Figure 1 As shown, in some embodiments, the metal foil 10 includes a substrate 100 and a metal layer 101. In some embodiments, the substrate 100 may be or may include painting paper, canvas, other suitable painting substrates, or combinations thereof, but this application is not limited thereto. In other embodiments, the substrate 100 may also be sketch paper or watercolor paper, other suitable paper substrates, or combinations thereof, but this application is not limited thereto. Taking watercolor paper as an example, watercolor paper can be further subdivided into cotton pulp paper and wood pulp paper. It is worth mentioning that this application may use any paper known to those skilled in the art as the substrate 100, and is not limited to the materials described above.

[0029] In some embodiments, the metal layer 101 may be or may include aluminum to simulate the metallic luster of silver. In this case, the metal foil 10 may be referred to as silver platinum. Alternatively, the aluminum metal layer 101 may be subjected to processes such as coating or the addition of an additional film layer (e.g., a plastic layer) to give the metal layer 101 a golden appearance, simulating the metallic luster of gold. In this case, the metal foil 10 may be referred to as gold platinum. However, this application is not limited thereto. In other embodiments, the metal layer 101 may also be or may include materials such as tin, gold, silver, other suitable metals, or combinations thereof to directly present or simulate the metallic luster of a particular metal.

[0030] In some embodiments, the metal layer 101 can be formed on the substrate 100 by an evaporation process. However, the present application is not limited thereto. In other embodiments, the metal layer 101 can be formed on the substrate 100 by offset printing, rolling, stamping or other suitable processes. In some embodiments, the metal layer 101 on the metal foil 10 can have hairline or water wave patterns, but the present application is not limited thereto. For example, the metal layer 101 on the metal foil 10 can be smooth or matte.

[0031] In some embodiments, the metal foil 10 can include the metal layer 101 and omit the substrate 100. In other words, the metal foil 10 can be a metal thin film. In some embodiments, the metal foil 10 can include the substrate 100 and the metal layer 101, and the material of the substrate 100 can be or include metal. In this case, the metal material of the substrate 100 is used to support the elements thereon, and the metal material of the metal layer 101 is used for the optical interference phenomenon with the light from the external environment. In some embodiments, the material of the substrate 100 can be similar to or the same as the material of the metal layer 101, but the present application is not limited thereto.

[0032] As shown in FIG. 1, the metal foil 10 includes a substrate 100 and a metal layer 101. The substrate 100 can be or include a metal foil, a plastic foil, a glass foil, a ceramic foil, a polymer foil, a composite foil or other suitable material. In some embodiments, the substrate 100 can be or include a metal foil, a plastic foil, a glass foil, a ceramic foil, a polymer foil or a composite foil, but the present application is not limited thereto. Figure 1 As shown in FIG. 1, the metal foil 10 includes a substrate 100 and a metal layer 101. The substrate 100 can be or include a metal foil, a plastic foil, a glass foil, a ceramic foil, a polymer foil, a composite foil or other suitable material. In some embodiments, the substrate 100 can be or include a metal foil, a plastic foil, a glass foil, a ceramic foil, a polymer foil or a composite foil, but the present application is not limited thereto.

[0033] For example, when the shielding rate of the shielding ink layer 12 on a specific area of the metal foil 10 is 100%, the shielding ink layer 12 completely blocks the light from the external environment from shining on the metal foil 10. In other words, the shielding ink layer 12 is completely opaque, so that the metal foil 10 is completely shielded by the shielding ink layer 12. On the other hand, when the shielding rate of the shielding ink layer 12 on another specific area of the metal foil 10 is 50%, the shielding ink layer 12 only partially shields (e.g., shields 50%) the light from the external environment from shining on the metal foil 10. In other words, the shielding ink layer 12 is partially transparent (e.g., 50% transmittance), so that the metal foil 10 is partially shielded by the shielding ink layer 12. It is worth mentioning that the relationship between the shielding rate and the transmittance mentioned above is only an example, and the present application is not limited thereto. In some embodiments, the relationship between the shielding rate and the transmittance can be positively correlated but not necessarily proportional.

[0034] As shown in FIG. 1, the metal foil 10 includes a substrate 100 and a metal layer 101. The substrate 100 can be or include a metal foil, a plastic foil, a glass foil, a ceramic foil, a polymer foil, a composite foil or other suitable material. In some embodiments, the substrate 100 can be or include a metal foil, a plastic foil, a glass foil, a ceramic foil, a polymer foil or a composite foil, but the present application is not limited thereto. Figure 1As shown, in some embodiments, the shading ink layer 12 can include a first portion 12a and a second portion 12b, and a first shading rate of the first portion 12a is different from a second shading rate of the second portion 12b. In this way, the color image can present a display effect with metallic luster in a specific area (e.g., the second portion 12b) by setting the shading ink layer 12 (e.g., the first shading rate is 100%) in an area (e.g., the first portion 12a) where the metallic luster is not desired to be presented, and by setting the shading ink layer 12 (e.g., the second shading rate is substantially 0%) with a coverage or thickness of almost 0 or substantially 0 in an area (e.g., the second portion 12b) where the metallic luster is desired to be presented.

[0035] In some embodiments, the color image can present a display effect with different metallic lusters in different areas (e.g., the first portion 12a and the second portion 12b) by setting more shading ink layer 12 (e.g., the first shading rate is 80%) in an area (e.g., the first portion 12a) where less metallic luster is desired to be presented, and by setting the shading ink layer 12 (e.g., the second shading rate is substantially 0%) with a coverage or thickness of almost 0 or substantially 0 in an area (e.g., the second portion 12b) where more metallic luster is desired to be presented.

[0036] Alternatively, the first shading rate of the first portion 12a of the shading ink layer 12 and the second shading rate of the second portion 12b of the shading ink layer 12 are both greater than 0%, and the first shading rate of the first portion 12a can be greater than or less than the second shading rate of the second portion 12b. For example, the color image can present a display effect with different metallic lusters in different areas (e.g., the first portion 12a and the second portion 12b) by setting more shading ink layer 12 (e.g., the first shading rate is 60%) in an area (e.g., the first portion 12a) where less metallic luster is desired to be presented, and by setting less shading ink layer 12 (e.g., the second shading rate is 30%) in an area (e.g., the second portion 12b) where more metallic luster is desired to be presented.

[0037] In the present application, the term "masking rate" can be achieved in various ways. For example, when the light-blocking ink layer 12 is disposed in an inkjet manner, the light-blocking ink sprayed by the inkjet head onto the metal foil 10 is dot-shaped ink of the same size and randomly distributed. Therefore, different masking rates of the light-blocking ink layer 12 can be achieved by adjusting the coverage (or density) of the dot-shaped light-blocking ink. For example, the coverage of the light-blocking ink layer 12 in a specific area (e.g., the first portion 12a and the second portion 12b) can be (substantially) 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, any value or range of values between the above-mentioned values, or any value to achieve the masking rates described above. It is worth mentioning that the relationship between the coverage mentioned above and the masking rate can be positively correlated but not necessarily proportional. In addition, in some cases, the higher the coverage, the thicker the thickness of the light-blocking ink layer 12 (because the dot-shaped ink can still overlap each other).

[0038] Alternatively, when the light-blocking ink layer 12 is disposed in a printing manner, the light-blocking ink coated (or transferred) by the printing device onto the metal foil 10 is one or more layers of ink, wherein the total thickness of the ink is positively correlated with the masking rate but not necessarily proportional. Therefore, the number of layers (or thickness) of the light-blocking ink layer 12 can be adjusted to achieve different masking rates. For example, the thickness (e.g., the first thickness t1 and the second thickness t2) of the light-blocking ink layer 12 in a specific area (e.g., the first portion 12a and the second portion 12b) can be 0.01 mm, 0.05 mm, 0.10 mm, 0.20 mm, 0.30 mm, 0.50 mm, 0.75 mm, 1.00 mm, any value or range of values between the above-mentioned values, or any value to achieve the masking rates described above, but the present application is not limited thereto.

[0039] In some embodiments, the light-blocking ink layer 12 can be or can include white ink, but the present application is not limited thereto. Specifically, since the spectrum of white color is composed of red color, blue color and green color (and their approximate colors), white color has a better reflection effect on light. In this way, the effect of blocking light from shining on the metal foil 10 can be achieved by disposing ink such as white ink (or near-white). However, the present application is not limited thereto. In other embodiments, the effect of blocking light from shining on the metal foil 10 can also be achieved by deep-colored ink such as black ink to absorb light. For example, the light-blocking ink layer 12 in a specific area (e.g., the first portion 12a and the second portion 12b) can include white ink, black ink, other suitable color ink, or a combination thereof.

[0040] In some embodiments, the light-blocking ink layer 12 can be or include a matrix and dispersed particles dispersed in the matrix, but the present application is not limited thereto. In some embodiments, the matrix can be or include a resin or a solvent, but the present application is not limited thereto. In some embodiments, the dispersed particles can be or include absorbing particles or scattering (reflecting) particles, but the present application is not limited thereto. In some embodiments, the dispersed particles can be or include white particles or black particles, but the present application is not limited thereto. In some embodiments, the weight percentage (or volume percentage) of the dispersed particles in the first portion 12a of the light-blocking ink layer 12 is greater than the weight percentage (or volume percentage) of the dispersed particles in the second portion 12b of the light-blocking ink layer 12, so as to achieve different shielding rates by adjusting the concentration of the dispersed particles.

[0041] It is worth mentioning that the light-blocking ink layer 12 can include more than two portions (i.e., other portions not belonging to the first portion 12a and the second portion 12b), so that the drawing structure 1 is not limited to only having two different metallic luster performances. For example, the light-blocking ink layer 12 can include a first portion 12a, a second portion 12b, …, and an Nth portion (not shown), and the shielding rates of each portion are different from each other. In this way, the color image can present more than two metallic luster brightnesses, hues, gradations, or stereoscopic effects (e.g., depth of field presented by different degrees of metallic luster). In addition, the above-mentioned manners are only used to make the present application clearer and easier to understand, and are not intended to limit the present application. In other embodiments, the present application can achieve different shielding rates in other manners. For example, the effect of adjusting the shielding rate can also be achieved by adjusting the concentration, color, or any combination of the above-mentioned manners of the light-blocking ink.

[0042] In some embodiments, the present application can also adjust the detailed structure of the light-blocking ink layer 12 to make the display effect of the drawing structure 1 more excellent. For example, the periphery of the light-blocking ink layer 12 can have a gradually decreasing thickness. For example, as shown in Figure 2 when the light-blocking ink layer 12 is a narrow line in the top view, the light-blocking ink layer 12 can be a trapezoidal structure in the cross-sectional view (e.g., the thickness of the periphery of the first portion 12a gradually decreases, or the thickness of the periphery of the second portion 12b gradually decreases), so as to avoid obvious steps between the light-blocking ink layer 12 and the surrounding, resulting in a rough surface of the drawing structure 1.

[0043] In addition, as shown in Figure 2 or Figure 3As shown, when the light-blocking ink layer 12 has two adjacent regions with a large difference in metallic luster (e.g., one is the first portion 12a and the other is the second portion 12b) in a plan view, one or more buffer portions 12c can be provided between the first portion 12a and the second portion 12b, so that the height difference between the first portion 12a and the second portion 12b gradually decreases in a gradient manner, thereby avoiding a clear step difference between the two portions (in the normal direction of the metal foil 10).

[0044] For example, the first portion 12a with a first shielding rate (or can be represented by a coverage rate) of 80% has a first thickness t1, and the second portion 12b with a second shielding rate (or can be represented by a coverage rate) of 40% has a second thickness t2, where the first thickness t1 is significantly greater than the second thickness t2. Therefore, to avoid the step difference between the first thickness t1 and the second thickness t2 causing the surface of the drawing structure 1 to be uneven, one or more buffer portions 12c (two in the example shown) can be provided between the first portion 12a and the second portion 12b, as shown. Figure 3 Figure 3 The buffer portions 12c have shielding rates of 60% and 40% and third and fourth thicknesses t3 and t4, and the third and fourth thicknesses t3 and t4 are between the first and second thicknesses t1 and t2. In this way, a clear step difference between the first portion 12a and the second portion 12b can be avoided.

[0045] It is worth mentioning that the above-mentioned values and configurations are only used to make the present application clearer and easier to understand, and are not intended to limit the present application. In other embodiments, the shielding rates, number, thicknesses of the first portion 12a, the second portion 12b, and the one or more buffer portions 12c can be determined according to actual conditions. For example, when the shielding rate difference (or thickness difference) between the first portion 12a and the second portion 12b is large, one, three, or more than three buffer portions 12c can be provided between the two to further reduce the step difference between the two adjacent regions.

[0046] Alternatively, in some embodiments, the thickness of the buffer portion 12c between the first portion 12a and the second portion 12b can also gradually decrease from one portion to the other portion. In this case, the upper surface of the buffer portion 12c can be a straight line with a slope from the cross-sectional view.

[0047] As shown, when the light-blocking ink layer 12 has two adjacent regions with a large difference in metallic luster (e.g., one is the first portion 12a and the other is the second portion 12b) in a plan view, one or more buffer portions 12c can be provided between the first portion 12a and the second portion 12b, so that the height difference between the first portion 12a and the second portion 12b gradually decreases in a gradient manner, thereby avoiding a clear step difference between the two portions (in the normal direction of the metal foil 10). Figure 1 ​As shown, in some embodiments, the width w1 of the first portion 12a or the width w2 of the second portion 12b of the light-shielding ink layer 12 is between 0.1 mm and 1000 mm, but this application is not limited to this. In other words, the light-shielding ink layer 12 of this application can have a narrower width (e.g., 0.1 mm), thus presenting a narrow linear structure. Conversely, the light-shielding ink layer 12 of this application can also have a wider width (e.g., 0.1 mm), thus presenting a broad plate-like (or sheet-like) structure. For example, the width w1 of the first portion 12a or the width w2 of the second portion 12b can be 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 1 mm, 5 mm, 10 mm, 100 mm, 500 mm, 1000 mm, or any value or any range of values ​​between the above values. Because the size range of the light-shielding ink layer 12 can be finely adjusted, the drawing structure 1 of this application can have fine alignment, thereby improving the resolution of the color image.

[0048] like Figure 1 As shown, a colored ink layer 14 is blanket-like disposed on the light-shielding ink layer 12 and the metal foil 10. By blanket-likely covering the light-shielding ink layer 12 and the metal foil 10 with the colored ink layer 14, the unevenness of the surface of the drawing structure 1 can be reduced. However, this application is not limited to this. In other embodiments, the step differences between the light-shielding ink layers 12 can be minimized as much as possible by one or more buffer portions 12c as described above or by other similar means. In this case, even if the colored ink layer 14 is conformally disposed on the light-shielding ink layer 12 and the metal foil 10, the unevenness of the surface of the drawing structure 1 can be reduced.

[0049] In some embodiments, in a top view, the total area of ​​the colored ink layer 14 is equal to the total area of ​​the metal foil 10, and the total area of ​​the colored ink layer 14 is greater than the total area of ​​the light-shielding ink layer 12. In other words, a portion of the metal foil 10 may not be covered by the light-shielding ink layer 12, and this portion of the metal foil 10 is in direct contact with the colored ink layer 14 (e.g., Figure 2 Region A). In the region where the metal foil 10 directly contacts the colored ink layer 14, the mixed light formed by the colored ink layer 14 and the metal foil 10 has the maximum metallic luster.

[0050] like Figure 1 As shown, in some embodiments, the colored ink layer 14 includes a third portion 14a and a fourth portion 14b, wherein the third portion 14a is disposed on the first portion 12a, and the fourth portion 14b is disposed on the second portion 12b. In this way, different metallic lusters under the same color or different colors can be achieved by adjusting the first occlusion rate of the first portion 12a and the second occlusion rate of the second portion 12b.

[0051] like Figure 4 As shown, in some embodiments, the third portion 14a of the colored ink layer 14 corresponds to and covers the first portion 12a of the light-shielding ink layer 12. For example, the third portion 14a of the colored ink layer 14 is red ink, and the first portion 12a of the light-shielding ink layer 12 is white ink with a 60% opacity. Compared to embodiments where the third portion 14a (i.e., red ink) is only disposed above the first portion 12a (i.e., white ink), covering the upper and side surfaces of the first portion 12a (i.e., white ink) with the third portion 14a (i.e., red ink) allows for better light mixing between the red ink, white ink, and metallic foil 10, resulting in a superior red pattern with a metallic sheen.

[0052] Similarly, such as Figure 4 As shown, in some embodiments, the fourth portion 14b of the colored ink layer 14 corresponds to and covers the second portion 12b of the light-shielding ink layer 12. For example, the fourth portion 14b of the colored ink layer 14 is yellow ink, and the second portion 12b of the light-shielding ink layer 12 is white ink with a 20% opacity. Compared to embodiments where the fourth portion 14b (i.e., yellow ink) is only disposed above the second portion 12b (i.e., white ink), covering the upper and side surfaces of the second portion 12b (i.e., white ink) with the fourth portion 14b (i.e., yellow ink) allows for better light mixing between the yellow ink, white ink, and metallic foil 10, resulting in a superior yellow (or gold) pattern with a metallic sheen.

[0053] In some embodiments, the first portion 12a and the second portion 12b of the light-shielding ink layer 12 are white inks with different opacities, and the third portion 14a and the fourth portion 14b of the colored ink layer 14 can be colored inks of similar or the same color. In this case, the same color with different metallic luster (e.g., red, green, blue, etc.) can be presented at different locations in the drawing structure 1. In some cases, the first portion 12a and the third portion 14a thereon can be disposed adjacent to one side of the second portion 12b and the fourth portion 14b thereon to highlight the same color with different metallic luster to the user's eyes.

[0054] As mentioned above, since the light-shielding ink layer 12 and the color ink layer 14 can be disposed by a coating process such as a printing process, and the precision can reach 0.1 mm as mentioned above, both of them can have excellent positioning effect. In practical application, the disposition of the light-shielding ink layer 12 and the color ink layer 14 can be planned by image editing software. For example, the image structure 1 of the present application can be formed by adjusting the image information corresponding to the color image, and outputting the image information to a printing device. In some embodiments, the image information corresponding to the color image can also be adjusted by image partitioning, so that different regions (which can be the same color or different colors) of the color image show more complex metallic luster. For example, a green pattern can show a first green metallic luster with a certain metallic luster and a second green metallic luster with a different metallic luster.

[0055] In some embodiments, the image information designed by the image editing software can obtain the image structure 1 as described in the present application after being output by an output device (for example, a printing device). The image structure 1 shows more than two metallic lusters in brightness, hue, gradation or stereoscopic effect (for example, the depth of field shown by different degrees of metallic luster) by adjusting the shielding rate of the light-shielding ink layer 12. For example, Figure 4 The third part 14a and the fourth part 14b in the third part 14a and the fourth part 14b both have metallic luster, and the metallic luster of the fourth part 14b is obviously brighter than the metallic luster of the third part 14a.
