Description

Drawing structure

This disclosure relates to drawing structures, and in particular to drawing structures capable of displaying different degrees of metallic luster.

In recent years, the level of detail in artworks has gradually gained attention. For example, religious colored images such as Thangka are usually based on guardian deities or Buddha statues with a metallic luster. In order to present the metallic luster, these metallic lusters can generally be achieved by forming a layer in the drawing structure, such as by setting hot stamping on colored ink. However, the metallic luster presented by this method is single, which is difficult to meet the user's demand for color images.

In other words, although drawing structures have gradually met their purpose, there are still some problems to be overcome. Therefore, how to provide a drawing structure that can display different degrees of metallic luster has become an urgent issue to be solved in this field.

In some embodiments, a drawing structure is provided, which includes a metal foil, a light-shielding ink layer, and a color ink layer. The light-shielding ink layer is disposed on the metal foil, wherein the light-shielding ink layer includes a first portion and a second portion, and a first shielding rate of the first portion is different from a second shielding rate of the second portion. The color ink layer is disposed on the light-shielding ink layer.

In some embodiments, the metal foil is silver foil.

In some embodiments, the light-shielding ink layer is white ink.

In some embodiments, the first shielding ratio of the first portion of the light-shielding ink layer and the second shielding ratio of the second portion of the light-shielding ink layer are both greater than 0%.

In some embodiments, the periphery of the light-shielding ink layer has a gradually decreasing thickness.

In some embodiments, the width of the first portion or the second portion of the light-shielding ink layer is between 0.1 mm and 1000 mm.

In some embodiments, the color ink layer is blanket-coated on the light-shielding ink layer and the metal foil.

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

In some embodiments, the color ink layer includes a third portion, which corresponds to the first portion and covers the first portion.

In some embodiments, the color ink layer further includes a fourth portion, which corresponds to the second portion and covers the second portion.

As mentioned above, the present disclosure provides a drawing structure in which a light-shielding ink layer is disposed between a color ink layer and a metal foil. By controlling various parameters of the light-shielding ink layer, the color image can present a variety of metallic lusters, thereby satisfying the needs of the user. In order to make the features and advantages of the present disclosure more obvious and easy to understand, various embodiments are specifically cited below, and detailed descriptions are given in conjunction with the attached drawings as follows.

It is worth noting that, according to standard industry practices, some features may not be drawn in scale.

The following disclosure provides many different embodiments or examples for implementing different components in the provided structure. Specific examples of each component and its configuration are described below to simplify the embodiments of the present disclosure, but are certainly not intended to limit the present disclosure. For example, if the description refers to a first component formed on a second component, it may include an embodiment in which the first component and the second component are directly in contact, and it may also include an embodiment in which an additional component is formed between the first component and the second component so that the first component and the second component are not directly in contact. In addition, the present disclosure may repeat component symbols and/or characters in different embodiments or examples. Such repetition is for simplicity and clarity, and is not used to indicate the relationship between the different embodiments and/or examples discussed.

The directional terms mentioned herein, such as "up", "down", "left", "right" and the like, are directions of reference drawings. Therefore, the directional terms used are used to illustrate rather than limit the present disclosure.

In some embodiments of the present disclosure, terms such as "disposed", "connected" and similar terms, unless otherwise specifically defined, may refer to two components being in direct contact, or may also refer to two components not being in direct contact, with an additional component located between the two structures. Terms related to disposition and connection may also include situations where both structures are movable, or where both structures are fixed.

In addition, the terms "first", "second" and similar terms mentioned in this specification or patent application are used to name different components or distinguish different embodiments or scopes, and are not used to limit the upper or lower limit of the number of components, nor are they used to limit the manufacturing order or setting order of the components.

In the following text, "approximately", "substantially" or similar terms mean within 10%, 5%, 3%, 2%, 1% or 0.5% of a given value or range of values. The quantities given here are approximate quantities, that is, in the absence of specific description of "approximately" or "substantially", the meaning of "approximately" or "substantially" can still be implied.

Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those of ordinary skill in the art. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant technology and the present disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined in the embodiments of the present disclosure.

Some variations of the embodiments are described below. In the different drawings and described embodiments, the same or similar element symbols are used to indicate the same or similar parts. It is understood that additional steps may be provided before, during, or after the method, and some of the described steps may be replaced or deleted for other embodiments of the method.

In the drawing structure, color ink can be placed on the drawing by printing, inkjet printing, etc., so that the color ink forms the color image to be presented. Furthermore, in order to make the color image have a richer and more diverse display effect, a more layered drawing structure can be formed. For example, a gold material layer can be placed on the color ink by methods such as screen printing, lithography, or hot stamping, so that the color image presents a metallic luster. However, this method is difficult to present gold with different hues, layers, and brightness on a single color image, and it is easy to have the problem of inaccurate overprinting (or superposition). In addition, by placing silver ink on the color ink to present the metallic luster, there is also the problem that the metallic luster is not bright enough and the color is not golden (it is gray). Similarly, the technique of attaching gold foil with glue still has the problem of insufficient resolution (i.e., insufficient precision) and difficulty in presenting different levels and brightness of gold.

To this end, the present disclosure provides a drawing structure in which a light-shielding ink layer is disposed between a color ink layer and a metal foil. By controlling various parameters of the light-shielding ink layer, the color image can present a variety of metallic lusters, thereby satisfying the needs of users.

Referring to Figures 1 to 5, Figures 1 to 4 are schematic cross-sectional views showing drawing structures according to some embodiments of the present disclosure, and Figure 5 is a schematic top view showing drawing structures according to some embodiments of the present disclosure. In some embodiments, Figures 1 to 4 may be schematic cross-sectional views of a single drawing structure 1 at different positions, but the present disclosure is not limited thereto. In other embodiments, Figures 1 to 4 may also be schematic cross-sectional views of different drawing structures 1.

As shown in FIG. 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, FIG. 1 (and FIG. 2 to FIG. 4) omits some possible elements or components. In other embodiments, a person with ordinary knowledge in the relevant technical field may set other elements or components such as adhesives on or between the above elements as required.

As shown in FIG. 1 , the metal foil 10 can be used as a substrate to support the light-shielding ink layer 12 and the color 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 color ink layer 14. For example, when the color ink layer 14 above the metal foil 10 is yellow, the light from the external environment will appear yellow (or gold) with a metallic luster after penetrating the color ink layer 14 and being reflected by the metal foil 10. Alternatively, when the color ink layer 14 above the metal foil 10 is green, the light from the external environment will appear green with a metallic luster after penetrating the color ink layer 14 and being reflected by the metal foil 10. In other words, the present disclosure can form various colors with metallic luster through light mixing between the metal foil 10 and the color ink layer 14.

As shown in FIG. 1, 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 the present disclosure 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 the present disclosure is not limited thereto. Taking watercolor paper as an example, watercolor paper can be further divided into cotton pulp paper and wood pulp paper. It is worth mentioning that the present application can use any paper known to a person of ordinary skill in the art as the substrate 100, without being limited to the above-mentioned materials.

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 a coating process or an additional film layer (e.g., a plastic layer) to make the metal layer 101 appear golden to simulate the metallic luster of gold. In this case, the metal foil 10 may be referred to as gold platinum. However, the present disclosure is not limited thereto. In other embodiments, the metal layer 101 may also be or may include tin, gold, silver, other suitable metals or combinations thereof to directly present or simulate the metallic luster of a specific metal.

In some embodiments, metal may be disposed on the substrate 100 by evaporation to form the metal layer 101. However, the present disclosure is not limited thereto. In other embodiments, metal may be disposed on the substrate 100 by offset printing, calendering, hammering or other suitable processes to form the metal layer 101. In some embodiments, the metal layer 101 on the metal foil 10 may have hairline or water ripples, but the present disclosure is not limited thereto. For example, the metal layer 101 on the metal foil 10 may be a smooth and bright surface or a matte surface.

In some embodiments, the metal foil 10 may include a metal layer 101 and the substrate 100 is omitted. In other words, the metal foil 10 may be a metal thin film. In some embodiments, the metal foil 10 may include a substrate 100 and a metal layer 101, and the material of the substrate 100 may be or may include metal. In this case, the metal material of the substrate 100 is used to support the components located thereon, and the metal material of the metal layer 101 is used to optically interfere with the light of the external environment. In some embodiments, the material of the substrate 100 may be similar or the same as the material of the metal layer 101, but the present disclosure is not limited thereto.

As shown in FIG. 1, the light-shielding ink layer 12 is disposed on the metal foil 10 to partially or completely shield the metal foil 10, so that light from the external environment cannot or can only partially interfere with the metal foil 10 (e.g., reflection and/or scattering). In this way, the display effect of the color image can be controlled by selectively disposing a light-shielding ink layer 12 with different shielding rates at a specific position of the metal foil 10.

For example, when the shielding rate of the light-shielding ink layer 12 on a specific area of the metal foil 10 is 100%, the light-shielding ink layer 12 completely blocks the light from the external environment from irradiating the metal foil 10. In other words, the light-shielding ink layer 12 is completely opaque, so that the metal foil 10 is completely shielded by the light-shielding ink layer 12. On the other hand, when the shielding rate of the light-shielding ink layer 12 on another specific area of the metal foil 10 is 50%, the light-shielding ink layer 12 can only partially shield (for example, block 50%) the light from the external environment from irradiating the metal foil 10. In other words, the light-shielding ink layer 12 is partially transparent (for example, the light transmittance is 50%), so that the metal foil 10 is partially shielded by the light-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 disclosure is not limited to this. In some embodiments, the relationship between the shielding rate and the transmittance may be positively correlated but not necessarily proportional.

As shown in FIG. 1, in some embodiments, the light-shielding ink layer 12 may include a first portion 12a and a second portion 12b, and the first shielding rate of the first portion 12a is different from the second shielding rate of the second portion 12b. In this way, by setting the light-shielding ink layer 12 (for example, the first shielding rate is 100%) in the area where the metallic luster is not to be presented (for example, the first portion 12a), and by setting the light-shielding ink layer 12 with a coverage rate or thickness of almost 0 or substantially 0 (for example, the second shielding rate is substantially 0%) in the area where the metallic luster is to be presented (for example, the second portion 12b), the color image can present a display effect with a metallic luster in a specific area (for example, the second portion 12b).

In some embodiments, a more shading ink layer 12 (e.g., the first masking rate is 80%) is provided in the area where less metallic gloss is to be presented (e.g., the first part 12a), and a shading ink layer 12 with a coverage rate or thickness of almost 0 or substantially 0 (e.g., the second masking rate is substantially 0%) is provided in the area where metallic gloss is to be presented (e.g., the second part 12b), so that the color image can present different metallic gloss display effects in different areas (e.g., the first part 12a and the second part 12b).

Alternatively, the first shielding rate of the first portion 12a of the light-shielding ink layer 12 and the second shielding rate of the second portion 12b of the light-shielding ink layer 12 are both greater than 0%, wherein the first shielding rate of the first portion 12a may be greater than or less than the second shielding rate of the second portion 12b. For example, by setting more light-shielding ink layers 12 (for example, the first shielding rate is 60%) in the area where less metallic gloss is to be presented (for example, the first portion 12a), and by setting less light-shielding ink layers 12 (for example, the second shielding rate is 30%) in the area where more metallic gloss is to be presented (for example, the second portion 12b), the color image can present different metallic gloss display effects in different areas (for example, the first portion 12a and the second portion 12b).

In the present disclosure, the term "masking rate" can be implemented in various ways. For example, when the light-shielding ink layer 12 is provided by inkjet printing, the light-shielding ink sprayed onto the metal foil 10 by the inkjet head is a dot-shaped ink of the same size and randomly distributed. Therefore, different masking rates of the light-shielding ink layer 12 can be achieved by adjusting the coverage rate (or density) of the dot-shaped light-shielding ink. For example, the coverage rate of the light-shielding 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 any range of values between the above values to achieve the above-mentioned masking rate. It is worth mentioning that the relationship between the coverage and the shielding rate mentioned above can be positively correlated but not necessarily proportional. In addition, in some cases, the higher the coverage, the thicker the light-shielding ink layer 12 may be (because the dot inks may still overlap each other).

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

In some embodiments, the light-shielding ink layer 12 may be or may include white ink, but the present disclosure is not limited thereto. Specifically, since the spectrum of white color is composed of red color, blue color and green color (and its approximate colors), white color has a better reflective effect on light. In this way, the effect of blocking light from irradiating the metal foil 10 can be achieved by setting ink such as white ink (or ink similar to white). However, the present disclosure is not limited thereto. In other embodiments, dark ink such as black ink can also be used to absorb light to achieve the effect of blocking light from irradiating the metal foil 10. For example, the light-shielding ink layer 12 can include white ink, black ink, other suitable color inks or a combination thereof in specific areas (e.g., the first part 12a and the second part 12b).

In some embodiments, the light-shielding ink layer 12 may be or may include a matrix and dispersed particles dispersed in the matrix, but the present disclosure is not limited thereto. In some embodiments, the matrix may be or may include a resin or a solvent, but the present disclosure is not limited thereto. In some embodiments, the dispersed particles may be or may include absorption particles or scattering (reflection) particles, but the present disclosure is not limited thereto. In some embodiments, the dispersed particles may be or may include white particles or black particles, but the present disclosure is not limited thereto. In some embodiments, the weight percentage (or volume percentage) of the dispersed particles in the first part 12a of the light-shielding ink layer 12 is greater than the weight percentage (or volume percentage) of the dispersed particles in the second part 12b of the light-shielding ink layer 12, so as to achieve different shielding rates by adjusting the concentration of the dispersed particles.

It is worth mentioning that the light-shielding ink layer 12 may include more than two parts (i.e., other parts that do not belong to the first part 12a and the second part 12b), so that the drawing structure 1 is not limited to having only two different metal gloss expressions. For example, the light-shielding ink layer 12 may include a first part 12a, a second part 12b...an Nth part (not shown), and the shielding rate of each part is different from each other. In this way, the color image can present more than two or more metal gloss brightness, hue, layering or three-dimensional sense (for example, the depth of field presented by different degrees of metal gloss). In addition, the above-mentioned methods are only used to make the present disclosure clearer and easier to understand, and are not intended to limit the present disclosure. In other embodiments, the present disclosure can achieve different shielding rates in other ways. For example, the effect of adjusting the shading rate can be achieved by adjusting the concentration or color of the light-shielding ink, or by any combination of the above methods.

In some embodiments, the present disclosure can also adjust the fine structure of the light-shielding ink layer 12 to make the display effect of the drawing structure 1 more excellent. For example, the periphery of the light-shielding ink layer 12 can have a gradually decreasing thickness. For example, as shown in FIG. 2, when the light-shielding ink layer 12 is a thin line with a narrow width in the top view, the light-shielding ink layer 12 can be made into a trapezoidal structure in the cross-sectional view (for example, the thickness of the periphery of the first part 12a gradually decreases, or the thickness of the periphery of the second part 12b gradually decreases) to avoid a significant step difference between the light-shielding ink layer 12 and the surroundings, resulting in an uneven surface of the drawing structure 1.

In addition, as shown in FIG. 2 or FIG. 3, when the light-shielding ink layer 12 is two adjacent areas with a large difference in metal gloss in a top view (for example, one is the first part 12a and the other is the second part 12b), one or more buffer parts 12c can be set between the first part 12a and the second part 12b, so that the height difference between the first part 12a and the second part 12b gradually decreases in a gradient manner, thereby avoiding a significant step difference between the two parts (in the normal direction of the metal foil 10).

For example, the first portion 12a with a first shielding rate (or coverage rate) of 80% has a first thickness t1, and the second portion 12b with a second shielding rate (or coverage rate) of 40% has a second thickness t2, wherein the first thickness t1 is significantly greater than the second thickness t2. Therefore, in order 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 FIG. 3) may be provided between the first portion 12a and the second portion 12b as shown in FIG. 3, wherein the buffer portion 12c has a shielding rate of 60% and 40% and a third thickness t3 and a fourth thickness t4, and the third thickness t3 and the fourth thickness t4 are between the first thickness t1 and the second thickness t2. In this way, there will be no obvious step difference between the first portion 12a and the second portion 12b.

It is worth mentioning that the above values and configurations are only used to make the present disclosure clearer and easier to understand, and are not intended to limit the present disclosure. In other embodiments, the shielding rate, quantity, and thickness of the first part 12a, the second part 12b, and one or more buffer parts 12c may be determined according to actual circumstances. For example, when the shielding rate difference (or thickness difference) between the first part 12a and the second part 12b is large, one, three, or more than three buffer parts 12c may be provided between the two to further reduce the step difference between the two adjacent areas.

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

As shown in FIG. 1 , in some embodiments, the width w1 of the first portion 12a of the light-shielding ink layer 12 or the width w2 of the second portion 12b is between 0.1 mm and 1000 mm, but the present disclosure is not limited thereto. In other words, the light-shielding ink layer 12 of the present disclosure may have a narrow width (e.g., 0.1 mm), thereby presenting a narrow linear structure. Conversely, the light-shielding ink layer 12 of the present disclosure may also have a wide width (e.g., 0.1 mm), thereby presenting a wide 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 may be 0.1mm, 0.2mm, 0.3mm, 0.5mm, 1mm, 5mm, 10mm, 100mm, 500mm, 1000mm or any value or any range of values therebetween. Since the size range of the light-shielding ink layer 12 can be finely adjusted, the drawing structure 1 disclosed herein can have fine alignment, thereby improving the resolution of the color image.

As shown in FIG. 1, the color ink layer 14 is blanket-coated on the light-shielding ink layer 12 and the metal foil 10. By blanket-coating the color ink layer 14 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. However, the present disclosure is not limited thereto. In other embodiments, the step difference between the light-shielding ink layers 12 can be reduced as much as possible by one or more buffer portions 12c as described above or other similar methods. In this case, even if the color 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.

In some embodiments, in a top view, the total area of the color ink layer 14 is equal to the total area of the metal foil 10, and the total area of the color 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 the portion of the metal foil 10 directly contacts the color ink layer 14 (e.g., area A in FIG. 2). In the area where the metal foil 10 directly contacts the color ink layer 14, the mixed light formed by the color ink layer 14 and the metal foil 10 has the maximum degree of metallic luster.

As shown in FIG. 1, in some embodiments, the color 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 glosses in the same color or different colors can be achieved by adjusting the first shading rate of the first portion 12a and the second shading rate of the second portion 12b.

As shown in FIG. 4, in some embodiments, the third portion 14a of the color ink layer 14 corresponds to the first portion 12a of the light-shielding ink layer 12 and covers the first portion 12a. For example, the third portion 14a of the color ink layer 14 is red ink, and the first portion 12a of the light-shielding ink layer 12 is white ink with a shielding rate of 60%. Compared with the embodiment in which the third portion 14a (i.e., red ink) is only disposed above the first portion 12a (i.e., white ink), the third portion 14a (i.e., red ink) covers the upper surface and side surface of the first portion 12a (i.e., white ink) to achieve a better light mixing effect between the red ink, the white ink and the metal foil 10, thereby presenting a better red pattern with a metallic luster.

Similarly, as shown in FIG. 4, in some embodiments, the fourth portion 14b of the color ink layer 14 corresponds to the second portion 12b of the light-shielding ink layer 12 and covers the second portion 12b. For example, the fourth portion 14b of the color ink layer 14 is yellow ink, and the second portion 12b of the light-shielding ink layer 12 is white ink with a 20% shielding rate. Compared with the embodiment in which the fourth portion 14b (i.e., yellow ink) is only disposed above the second portion 12b (i.e., white ink), the fourth portion 14b (i.e., yellow ink) covers the upper and side surfaces of the second portion 12b (i.e., white ink) to achieve a better light mixing effect between the yellow ink, the white ink and the metal foil 10, thereby presenting a more excellent yellow (or gold) pattern with a metallic luster.

In some embodiments, the first portion 12a and the second portion 12b of the light-shielding ink layer 12 are white inks with different shielding rates, and the third portion 14a and the fourth portion 14b of the color ink layer 14 may be color inks of similar or identical colors. In this case, the same color (e.g., red, green, blue, etc.) with different metallic lusters may be presented at different locations of the drawing structure 1. In some cases, the first portion 12a and the third portion 14a thereon may 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 lusters in the eyes of the user.

As mentioned above, since the light-shielding ink layer 12 and the color ink layer 14 can be set by a coating process such as a printing process, and the accuracy can reach 0.1 mm as described above, both can have excellent positioning effects. In practical applications, the setting of the light-shielding ink layer 12 and the color ink layer 14 can be planned by image editing software. For example, the drawing structure 1 disclosed herein 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 be adjusted by dividing the image so that different areas of the color image (which can be the same color or different colors) present a more complex metallic luster. For example, a green pattern can be made to present a first green metallic light with a specific metallic luster and a second green metallic light with a different metallic luster.

In some embodiments, the image information designed by the image editing software can be outputted through an output device (e.g., a printing device) to obtain a drawing structure 1 as described in the present disclosure. The drawing structure 1 adjusts the shading rate of the light-shielding ink layer I2 to present more than two kinds of metallic luster brightness, hue, layering or stereoscopic feeling (e.g., depth of field presented by different degrees of metallic luster) in the thangka as shown in FIG. 5 (but not limited to). For example, the third part 14a and the fourth part 14b in FIG. 5 both have metallic luster, and the metallic luster of the fourth part 14b is significantly brighter than the metallic luster of the third part 14a.
