Design printing device and method utilizing magnetic phenomenon

[0001] The present invention relates to a design printing device and method utilizing a magnetic phenomenon, and more particularly, to a design printing device and method utilizing a magnetic phenomenon capable of three-dimensional expression by inducing a magnetic field so that a magnetic field is applied to a printing surface before magnetic ink containing a magnetic substance is cured, even when it is difficult for a jig to be positioned below a printing surface or when a printing medium is thick, and utilizing a light reflection effect in which the angle at which the magnetic substance is oriented is formed differently according to the magnetic field and the shape in which the magnetic substance reflects light differently appears.

[0002] As the proportion of design in products continues to increase, the design-first, component-first approach is being introduced in product design and manufacturing, and exterior design is having a significant impact on marketability.

[0003] This is no exception in the case of pattern design on the surface of a product, and various design techniques that provide unique effects are being introduced.

[0004] Among these design techniques are magnetic ink containing magnetic substances (particles) and design printing technology utilizing magnetic phenomena.

[0005] Design printing technology using magnetic ink and magnetic phenomena is a technology that enables three-dimensional expression by utilizing the light reflection effect in which the angle at which the magnetic material is oriented is formed differently depending on the magnetic field, and the shape in which the magnetic material reflects light is different.

[0006] Korean Patent Publication No. 1881037 (published on July 17, 2018, hereinafter referred to as “Prior Art 1”) discloses a method for forming a pattern using magnetic ink and magnetic force.

[0007] Prior art 1 introduces a technology for forming a design that matches the uneven pattern by placing a product having a printed surface (surface of the product) coated with magnetic ink on the upper side of a jig and applying a magnetic field to the jig.

[0008] However, this method has a problem in that the print quality deteriorates as the distance between the surface of the jig that applies the magnetic field and the printing surface where the magnetic ink is applied increases, making it difficult to print on thick products.

[0054] As illustrated in FIGS. 1 to 3, a design printing device utilizing a magnetic phenomenon according to one embodiment of the present invention includes a magnetic field surface induction unit (100) and a magnetic field application unit (200).

[0055] The magnetic field surface induction unit (100) is provided so that one side faces the printed surface (11) of the product (10), and induces a magnetic field on the printed surface (11) of the product (10).

[0056] The above magnetic field surface induction unit (100) induces a magnetic field generated from the magnetic field application unit (200) described below to one side of the printed surface (11) of the product (10).

[0057] For this purpose, one side of the printed surface (11) of the above product (10) and one side of the magnetic field surface induction unit (100) are provided to face each other.

[0058] The above magnetic field surface induction unit (100) can be formed of a mixed material of a soft magnetic material, a hard magnetic material, and a non-magnetic material, and any material that can induce a magnetic field generated from the magnetic field application unit (200) described below to one side of the printed surface (11) of the product (10) can be used.

[0059] Representative soft magnetic materials capable of forming the above magnetic field surface induction portion (100) include at least one material selected from among iron, cobalt, and nickel, a synthetic material (alloy, etc.) containing at least one material selected from among iron, cobalt, and nickel, and a representative hard magnetic material includes a permanent magnet.

[0060] The above magnetic field surface induction unit (100) is configured to induce a magnetic field on one side of the printed surface (11) of the product (10), and is provided on one side of the surface of the product (10) where printing of the product (10) is to be performed. At this time, it is preferable that the magnetic field surface induction unit (100) is provided so as to be spaced apart from the product (10) by a certain distance. Here, the printed surface (11) may be a part of the surface of the product (10).

[0061] The magnetic field generating unit (200) is provided on the other side of the product (10) or the other side of the magnetic field surface induction unit (100) and generates a magnetic field.

[0062] The above magnetic field applying unit (200) generates a magnetic field so that a magnetic field can be induced in the magnetic field surface induction unit (100), and as a result, a magnetic field is applied to one side of the printed surface (11) of the product (10) with the help of the magnetic field surface induction unit (100).

[0063] The position at which the magnetic field applying unit (200) is provided can be implemented in various ways. As a representative example, as shown in FIGS. 1 and 2, it can be provided on the other side of the product (10), and as shown in FIG. 3, it can be provided on the other side of the magnetic field surface induction unit (100).

[0064] As shown in Fig. 3, when the magnetic field applying unit (200) is provided on the other side of the magnetic field surface induction unit (100), it is also possible for the magnetic field surface induction unit (100) to be provided in close contact with the magnetic field applying unit (200).

[0065] The above magnetic field applying unit (200) may include at least one selected from among a permanent magnet and an electromagnet, and any material may be used as long as it can generate a magnetic field of a desired shape.

[0066] At this time, the design printing device utilizing the magnetic phenomenon according to one embodiment of the present invention is characterized in that the magnetic ink containing the magnetic substance (particle) applied to one printing surface (11) of the product (10) is exposed to a magnetic field, so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, and the shape in which the magnetic substance reflects light appears differently, thereby hardening the magnetic ink so that a three-dimensional effect can be expressed according to the reflection of light, so that the printing result of the flat (2D) structure appears as a printing result of the three-dimensional (3D) structure.

[0067] That is, the magnetic field generated from the magnetic field applying unit (200) is applied to the magnetic ink applied to the printing surface (11) of the product (10) by the magnetic field surface induction unit (100), so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, so that the shape in which the magnetic substance reflects light appears differently, thereby hardening the magnetic ink to produce a three-dimensional effect according to the reflection of light, and thereby the printing result of the flat (2D) structure appears as a printing result of the three-dimensional (3D) structure.

[0068] Here, the printing result of a flat (2D) structure is not limited to flat printing, and refers to a case where magnetic ink is applied to form the same / similar thickness on the printing surface (11).

[0069] That is, a printing result in which magnetic ink is applied in a multi-faceted flat shape printed on a flat product (10) can be called a printing result in a flat (2D) structure, and a printing result in which magnetic ink is applied in a multi-faceted hemispherical shape printed on a hemispherical product (10) can be called a printing result in a flat (2D) structure.

[0070] The printed result of a flat (2D) structure printed in this way can appear as a three-dimensional (3D) structure depending on the direction from which the printed result is viewed, as long as the direction in which the light shines is constant.

[0071] As illustrated in FIG. 4, the magnetic field surface induction unit (100) of the design printing device utilizing a magnetic phenomenon according to one embodiment of the present invention may be characterized by being formed in a three-dimensional shape including at least one selected from among a concave-convex shape (a), a curved shape (b), and a shape in which a through hole is formed (c).

[0072] Any form that allows for three-dimensional expression, such as a relief form, a positive form, a negative form, or a form where both positive and negative forms are flat, can be implemented.

[0073] In addition, in FIG. 4, a three-dimensional shape in the form of an intaglio is illustrated on one surface of the magnetic field surface induction unit (100), but the present invention is not limited thereto, and various implementations are possible, such as forming a three-dimensional shape on the other surface of the magnetic field surface induction unit (100).

[0074] The form in which the through hole is formed is a form in which a part of the magnetic field surface induction part (100) is penetrated in a specific shape.

[0075] In Fig. 4, an example in which the magnetic field surface induction part (100) is formed in a three-dimensional shape is given, but the present invention is not limited thereto, and it goes without saying that the magnetic field rear induction part (300) described later can also be formed in a three-dimensional shape.

[0076] The magnetic field surface induction unit (100) of a design printing device utilizing a magnetic phenomenon according to one embodiment of the present invention may be characterized by being formed by a combination of magnetic domains in which a plurality of magnetic domains, which are spatial regions having the same magnetization direction, are spatially formed.

[0077] A spatial region with the same magnetization direction is called a magnetic domain.

[0078] Therefore, a combination of multiple magnetic domains means a combination of multiple magnetic domains having different magnetization directions.

[0079] Taking Fig. 5 as an example, the part (d) diagonally oriented in one direction of the magnetic field surface induction part (100) can be formed so that the magnetization direction is directed toward the center of the hemisphere, and the part (e) diagonally oriented in the other direction of the magnetic field surface induction part (100) can be formed so that the magnetization direction is opposite to that.

[0080] That is, due to the different magnetization directions of the magnetic domain layers, the arrangement direction of the magnetic substances (magnetic particles) mixed in the magnetic ink changes depending on the location, and as a result, an arrangement of magnetic substances (magnetic particles) is formed that exhibits different optical effects, including three-dimensionality, height and depth of engraving and relief, and light and shade, depending on the direction of light incident on the printing surface (11).

[0081] The above magnetic field surface induction unit (100) can only change the shape of the magnetic domain without changing the physical shape of the above magnetic field surface induction unit (100).

[0082] At this time, it is also possible to transform the shape of the magnet into three dimensions.

[0083] In other words, the magnetic field surface induction unit (100) may be formed as a single magnetic domain before forming a magnetic domain, and the shape of the magnetic domain may be modified to design it into a desired shape.

[0084] For example, the magnetic field surface induction part (100) may be formed in a plate shape (see FIGS. 1 and 2), and the first magnetic domain may form a three-dimensional shape of a specific type in the form of an intaglio from one side of the magnetic field surface induction part (100) and may have a magnetization direction from the top to the bottom, and the second magnetic domain may correspond to the remaining area of ​​the magnetic field surface induction part (100) in a form that surrounds the side and the top of the first magnetic domain and may have a magnetization direction from the bottom to the top.

[0085] The magnetic field surface induction part (100) in which such a magnetic field is formed can induce a magnetic field similar to the structure formed by the intaglio on one side of the magnetic field surface induction part (100) to one side of the printed surface (11) of the product (10).

[0086] That is, the magnetic field surface induction unit (100) may be composed of a plurality of magnetic domains having different magnetization directions.

[0087] Although an example of a magnetic field surface induction unit (100) in which two magnetic domains are formed is given above, the present invention is not limited thereto, and various implementations combining various types of magnetic domains and magnetization directions are of course possible.

[0088] In the above, an example in which the magnetic field surface induction part (100) is formed by a combination of multiple magnetic domains was given, but the present invention is not limited thereto, and it goes without saying that the magnetic field rear induction part (300) described later can also be formed by a combination of multiple magnetic domains.

[0089] As illustrated in FIG. 6, the magnetic field applying unit (200) of the design printing device utilizing a magnetic phenomenon according to one embodiment of the present invention includes a permanent magnet or an electromagnet, and may include a magnetic field generating unit (210) that generates a magnetic field and a magnetic field rectifying unit (220) that rectifies the magnetic field so that the magnetic field is induced to one printing surface (11) of the product (10).

[0090] The above magnetic field rectification unit (220) is configured to rectify a magnetic field, and serves to reduce or block the influence of magnetic fields generated from other electrical devices or electronic equipment, thereby enabling printing of more precise designs.

[0091] That is, the magnetic field rectifier (220) plays a role in reducing or eliminating noise.

[0092] At this time, it is also possible for the magnetic field surface induction unit (100) to be installed in close contact with the magnetic field rectification unit (220).

[0093] If the above magnetic field rectification unit (220) is provided, high-quality printing is possible even when printing by reducing the strength of the magnetic field, and higher-quality printing is possible by more precisely controlling the direction of the magnetic field.

[0094] As illustrated in FIG. 7, a design printing device utilizing a magnetic phenomenon according to one embodiment of the present invention includes a magnetic field rear induction unit (300) and a magnetic field application unit (200).

[0095] The magnetic field rear induction unit (300) is provided so that one side of the back surface and one side of the printed surface (11) of the product (10) are opposite each other, thereby inducing a magnetic field to the printed surface (11) of the product (10).

[0096] The above magnetic field rear induction unit (300) induces a magnetic field generated from the magnetic field application unit (200) described below to one side of the printed surface (11) of the product (10).

[0097] For this purpose, the back surface of one side of the printed surface (11) of the above product (10) and one side of the magnetic field rear induction part (300) are provided to face each other.

[0098] The above magnetic field rear induction part (300) can be formed of a mixed material of a soft magnetic material, a hard magnetic material, and a non-magnetic material, and any material that can induce a magnetic field generated from the magnetic field application part (200) described below to one side of the printed surface (11) of the product (10) can be used.

[0099] Representative soft magnetic materials capable of forming the above magnetic field rear induction part (300) include at least one material selected from among iron, cobalt, and nickel, a synthetic material (alloy, etc.) containing at least one material selected from among iron, cobalt, and nickel, and a representative hard magnetic material includes a permanent magnet.

[0100] The above magnetic field rear induction unit (300) is configured to induce a magnetic field on one side of the printed surface (11) of the product (10), and is provided on the back side of the printed surface (11), which is the surface side of the product (10) on which printing of the product (10) is to be performed. At this time, the magnetic field rear induction unit (300) may be provided in close contact with the product (10), or may be provided at a certain distance from the product (10). Here, the printed surface (11) may be a part of the surface of the product (10).

[0101] The magnetic field generating unit (200) is provided so that one side faces the printed surface (11) of the product (10) and generates a magnetic field.

[0102] The above magnetic field applying unit (200) generates a magnetic field so that a magnetic field can be induced in the magnetic field rear induction unit (300), and as a result, a magnetic field is applied to one side of the printed surface (11) of the product (10) with the help of the magnetic field rear induction unit (300).

[0103] The position at which the magnetic field applying unit (200) is provided can be implemented in various ways, and as a representative example, it can be provided on one side of the printed surface (11) of the product (10), as shown in FIG. 7.

[0104] As shown in Fig. 7, when the magnetic field applying unit (200) is provided on one side of the printed surface (11) of the product (10), it is preferable that it be provided at a certain distance from the product (10).

[0105] The above magnetic field applying unit (200) may include at least one selected from among a permanent magnet and an electromagnet, and any material may be used as long as it can generate a magnetic field of a desired shape.

[0106] At this time, the design printing device utilizing the magnetic phenomenon according to one embodiment of the present invention is characterized in that the magnetic ink containing the magnetic substance (particle) applied to one printing surface (11) of the product (10) is exposed to a magnetic field, so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, and the shape in which the magnetic substance reflects light appears differently, thereby hardening the magnetic ink so that a three-dimensional effect can be expressed according to the reflection of light, so that the printing result of the flat (2D) structure appears as a printing result of the three-dimensional (3D) structure.

[0107] That is, the magnetic field generated from the magnetic field applying unit (200) is applied to the magnetic ink applied to the printing surface (11) of the product (10) by the magnetic field rear induction unit (300), so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, thereby causing the magnetic substance to reflect light differently, thereby hardening the magnetic ink to produce a three-dimensional effect according to the reflection of light, and thereby causing the printed result of a flat (2D) structure to appear as a printed result of a three-dimensional (3D) structure.

[0108] Here, the printing result of a flat (2D) structure is not limited to flat printing, and refers to a case where magnetic ink is applied to form the same / similar thickness on the printing surface (11).

[0109] That is, a printing result in which magnetic ink is applied in a multi-faceted flat shape printed on a flat product (10) can be called a printing result in a flat (2D) structure, and a printing result in which magnetic ink is applied in a multi-faceted hemispherical shape printed on a hemispherical product (10) can be called a printing result in a flat (2D) structure.

[0110] The printed result of a flat (2D) structure printed in this way can appear as a three-dimensional (3D) structure depending on the direction from which the printed result is viewed, as long as the direction in which the light shines is constant.

[0111] If there is a relief-like shape on the lower part of the product (10), the printing result shows a relief printing effect, and if there is a relief-like shape on the upper part of the product (10), the printing result shows a negative printing effect.

[0112] In addition, if there is a negative projection shape on the lower part of the product (10), the printing result shows a negative printing effect, and if there is a negative projection shape on the upper part of the product (10), the printing result shows a relief printing effect.

[0113] The above magnetic field surface induction unit (100) or magnetic field rear induction unit (300) may be made of a flexible material and may be made to be deformed into a curved shape corresponding to the curved surface (11) of the product (10).

[0114] The above magnetic field surface induction unit (100) or magnetic field rear induction unit (300) can be implemented by filling metal clay into a housing (mold) having a three-dimensional shape.

[0115] Metal clay can be composed of metal powder and resin.

[0116] At this time, the housing can be formed of a material that does not affect the magnetic field. For example, silicon can be used.

[0117] Additionally, the housing can also be manufactured using a 3D printer.

[0118] Here, the housing can serve as a mold and also as a frame for fixing the metal clay.

[0119] That is, after printing is performed with the housing filled with metal clay, the metal clay used in printing can be recovered and reused for other printing.

[0120] In other words, when producing small quantities of various products, only the housing needs to be replaced, and the metal clay can be reused, reducing printing costs.

[0121] The above magnetic field surface induction unit (100) or magnetic field rear induction unit (300) can also be manufactured using a metal 3D printer. In this case, the magnetic field surface induction unit (100) or magnetic field rear induction unit (300) can be fixed by a fixed frame made of a non-magnetic material.

[0122] The configuration for fixing the magnetic field surface induction unit (100), magnetic field applying unit (200), and magnetic field rear induction unit (300) can be formed of a non-magnetic material.

[0123] This is to minimize changes in the magnetic field and obtain high-quality printing results.

[0124] As illustrated in FIG. 8, a design printing device utilizing a magnetic phenomenon according to one embodiment of the present invention includes a magnetic field surface induction unit (100) and a magnetic field application unit (200), and the magnetic field application unit (200) may be provided on the other side of the magnetic field surface induction unit (100) and the other side of the product (10).

[0125] That is, a magnetic field can be generated on both sides of the above product (10).

[0126] This makes it possible to use a magnetic field applying unit (200) with a smaller output than generating a magnetic field on only one side, and can reduce external noise.

[0127] As illustrated in FIG. 9, a design printing method utilizing a magnetic phenomenon according to one embodiment of the present invention includes a transfer step (S30), a design formation step (S40), and a drying step (S50).

[0128] The transfer step (S30) moves the product (10) or the magnetic field surface induction unit (100) and the magnetic field application unit (200) so that the product (10) is positioned within the magnetic field influence zone of the magnetic field surface induction unit (100) that is provided so that one side of the magnetic field application unit (200) faces the one side of the printed surface (11) of the product (10) and induces the magnetic field generated from the magnetic field application unit (200) to the one side of the printed surface (11) of the product (10).

[0129] That is, it is possible to move the product (10) into the magnetic field influence zone, and it is also possible to generate a magnetic field influence zone on the product by moving the magnetic field surface induction unit (100) and the magnetic field application unit (200) while the product (10) is fixed. For example, after magnetic ink is applied to the body, such as the exterior of a car, the magnetic field surface induction unit (100) and the magnetic field application unit (200) are moved, and then a magnetic field is applied in the design formation step (S40) described later.

[0130] The above-mentioned transfer step (S30) is for moving the product (10) or the magnetic field surface induction unit (100) and the magnetic field application unit (200) to an area for design printing using a magnetic phenomenon, and the product (10) or the magnetic field surface induction unit (100) and the magnetic field application unit (200) are moved so that one side of the printed surface (11) of the product (10) is positioned within the magnetic field influence zone of the magnetic field application unit (200) and the magnetic field rear induction unit (300).

[0131] The design formation step (S40) generates a magnetic field from the magnetic field applying unit (200), and the magnetic field generated from the magnetic field applying unit (200) is applied to the printing surface (11) on which magnetic ink containing a magnetic substance (particle) is applied, and the magnetic field surface induction unit (100) induces the magnetic field to one printing surface (11) of the product (10) so that the design to be printed is formed on the printing surface (11) on which the magnetic ink is applied.

[0132] The above design formation step (S40) is to form the design to be printed on the printing surface (11) to which the magnetic ink is applied, and the design to be printed is actually revealed in the design formation step (S40).

[0133] The drying step (S50) dries the magnetic ink on the printing surface (11).

[0134] The above drying step (S50) dries the magnetic ink in which the design to be printed is formed.

[0135] The above drying step (S50) may be applied with various drying methods, such as a method of drying the magnetic ink in which the design to be printed is formed by increasing the temperature, a method of drying the magnetic ink in which the design to be printed is formed by using light (light such as infrared rays, visible rays, or ultraviolet rays), and a natural drying method, depending on the characteristics of the magnetic ink.

[0136] At this time, the design printing method utilizing a magnetic phenomenon according to one embodiment of the present invention is characterized in that the magnetic ink containing a magnetic substance (particle) applied to one side of the printing surface (11) of the product (10) is exposed to a magnetic field, so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, and the shape in which the magnetic substance reflects light appears differently, thereby hardening the magnetic ink so that a three-dimensional effect can be expressed according to the reflection of light, so that the printing result of a flat (2D) structure appears as a printing result of a three-dimensional (3D) structure.

[0137] That is, the magnetic field generated from the magnetic field applying unit (200) is applied to the magnetic ink applied to the printing surface (11) of the product (10) by the magnetic field surface induction unit (100), so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, so that the shape in which the magnetic substance reflects light appears differently, thereby hardening the magnetic ink to produce a three-dimensional effect according to the reflection of light, and thereby the printing result of the flat (2D) structure appears as a printing result of the three-dimensional (3D) structure.

[0138] Here, the printing result of a flat (2D) structure is not limited to flat printing, and refers to a case where magnetic ink is applied to form the same / similar thickness on the printing surface (11).

[0139] That is, a printing result in which magnetic ink is applied in a multi-faceted flat shape printed on a flat product (10) can be called a printing result in a flat (2D) structure, and a printing result in which magnetic ink is applied in a multi-faceted hemispherical shape printed on a hemispherical product (10) can be called a printing result in a flat (2D) structure.

[0140] The printed result of a flat (2D) structure printed in this way can appear as a three-dimensional (3D) structure depending on the direction from which the printed result is viewed, as long as the direction in which the light shines is constant.

[0141] As illustrated in FIG. 9, a design printing method utilizing a magnetic phenomenon according to one embodiment of the present invention includes a transfer step (S30), a design formation step (S40), and a drying step (S50).

[0142] The transfer step (S30) moves the product (10) or the magnetic field back induction unit (300) and the magnetic field application unit (200) so that the product (10) is positioned within the magnetic field influence zone of the magnetic field application unit (200) which is provided so that one side of the printed surface (11) of the product (10) faces the other side and generates a magnetic field, and the magnetic field back induction unit (300) which is provided so that one side of the printed surface (11) of the product (10) faces the other side and induces the magnetic field generated from the magnetic field application unit (200) to the printed surface (11) of the product (10).

[0143] That is, it is possible to move the product (10) into the magnetic field influence zone, and it is also possible to generate a magnetic field influence zone on the product by moving the magnetic field rear induction unit (300) and the magnetic field application unit (200) while the product (10) is fixed.

[0144] The above-mentioned transfer step (S30) is for moving the product (10) or the magnetic field rear induction unit (300) and the magnetic field application unit (200) to an area for design printing using a magnetic phenomenon, and the product (10) or the magnetic field rear induction unit (300) and the magnetic field application unit (200) are moved so that one side of the printed surface (11) of the product (10) is positioned within the magnetic field influence zone of the magnetic field application unit (200) and the magnetic field rear induction unit (300).

[0145] The design formation step (S40) generates a magnetic field from the magnetic field applying unit (200), and the magnetic field generated from the magnetic field applying unit (200) is induced by the magnetic field rear induction unit (300) to one side of the printing surface (11) of the product (10) on which magnetic ink containing a magnetic substance (particle) is applied, so that the design to be printed is formed on the printing surface (11) on which the magnetic ink is applied.

[0146] The above design formation step (S40) is to form the design to be printed on the printing surface (11) to which the magnetic ink is applied, and the design to be printed is actually revealed in the design formation step (S40).

[0147] The drying step (S50) dries the magnetic ink on the printing surface (11).

[0148] The above drying step (S50) dries the magnetic ink in which the design to be printed is formed.

[0149] The above drying step (S50) may be applied with various drying methods, such as a method of drying the magnetic ink in which the design to be printed is formed by increasing the temperature, a method of drying the magnetic ink in which the design to be printed is formed by using light (light such as infrared rays, visible rays, or ultraviolet rays), and a natural drying method, depending on the characteristics of the magnetic ink.

[0150] At this time, the design printing method utilizing a magnetic phenomenon according to one embodiment of the present invention is characterized in that the magnetic ink containing a magnetic substance (particle) applied to one side of the printing surface (11) of the product (10) is exposed to a magnetic field, so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, and the shape in which the magnetic substance reflects light appears differently, thereby hardening the magnetic ink so that a three-dimensional effect can be expressed according to the reflection of light, so that the printing result of a flat (2D) structure appears as a printing result of a three-dimensional (3D) structure.

[0151] That is, the magnetic field generated from the magnetic field applying unit (200) is applied to the magnetic ink applied to the printing surface (11) of the product (10) by the magnetic field surface induction unit (100), so that the angle at which the magnetic substance inside the magnetic ink is oriented is formed differently according to the magnetic field, so that the shape in which the magnetic substance reflects light appears differently, thereby hardening the magnetic ink to produce a three-dimensional effect according to the reflection of light, and thereby the printing result of the flat (2D) structure appears as a printing result of the three-dimensional (3D) structure.

[0152] Here, the printing result of a flat (2D) structure is not limited to flat printing, and refers to a case where magnetic ink is applied to form the same / similar thickness on the printing surface (11).

[0153] That is, a printing result in which magnetic ink is applied in a multi-faceted flat shape printed on a flat product (10) can be called a printing result in a flat (2D) structure, and a printing result in which magnetic ink is applied in a multi-faceted hemispherical shape printed on a hemispherical product (10) can be called a printing result in a flat (2D) structure.

[0154] The printed result of a flat (2D) structure printed in this way can appear as a three-dimensional (3D) structure depending on the direction from which the printed result is viewed, as long as the direction in which the light shines is constant.

[0155] Since the magnetic field surface induction unit (100) or the magnetic field application unit (200) is positioned on the printing surface (11) of the product (10) from the above design formation step (S40), it is difficult to apply magnetic ink on the printing surface (11) of the product (10).

[0156] Therefore, the process of applying magnetic ink to the product and the process of applying a magnetic field can be separated.

[0157] The process of applying magnetic ink to the product may be performed during the above-mentioned transfer step (S30) or may be performed before the transfer step (S30), and this will be described below.

[0158] The transfer step (S30) of the design printing method utilizing a magnetic phenomenon according to one embodiment of the present invention may be characterized by applying magnetic ink containing a magnetic substance (particle) to one printing surface (11) of the product (10) while moving the product (10) to a designated location.

[0159] For example, a magnetic ink spray nozzle may be installed on one edge of a component (surface induction unit (100) or magnetic field application unit (200)) located on the printing surface (11) of the product (10), and magnetic ink may be applied while the printing surface (11) of the product (10) passes the magnetic ink spray nozzle.

[0160] As illustrated in FIG. 10, a design printing method utilizing a magnetic phenomenon according to one embodiment of the present invention may include an ink application step (S20) of applying magnetic ink containing a magnetic substance (particle) to one printing surface (11) of a product (10) prior to the transfer step (S30).

[0161] The above ink application step (S20) forms a printing layer by applying magnetic ink to the printing surface (11) of the product (10). Various printing methods can be applied as long as a printing layer can be formed by applying magnetic ink to the printing surface (11), such as silk printing, spray printing, gravure printing, offset printing, and pad printing (stamp printing).

[0162] As illustrated in FIG. 11, a design printing method utilizing a magnetic phenomenon according to one embodiment of the present invention may include a printing preparation step (S10) of preparing a configuration selected from among the magnetic field surface induction unit (100) and the magnetic field application unit (200) so as to form a magnetic field according to a design to be printed on one printing surface (11) of the product (10) prior to the transfer step (S30).

[0163] The above printing preparation step (S10) is a step of preparing a magnetic field surface induction unit (100) or a magnetic field rear induction unit (300) that induces a magnetic force to form a design to be printed, or preparing a magnetic field application unit (200) that generates a magnetic force to form a design to be printed.

[0164] That is, a three-dimensional shape or magnetic domain for forming a design to be printed can be formed in the magnetic field surface induction unit (100), the magnetic field rear induction unit (300), or the magnetic field application unit (200).

[0165] Here, there is a difference between the design to be printed and the three-dimensional shape or domain formed in the magnetic field surface induction unit (100), the magnetic field rear induction unit (300), or the magnetic field application unit (200) to form the design to be printed.

[0166] For example, when a three-dimensional shape is formed on the magnetic field surface induction part (100), there is a difference between the three-dimensional shape formed on the magnetic field surface induction part (100) and the three-dimensional shape shown in the printed result.

[0167] At this time, it is easy to infer the three-dimensional shape shown in the printed result after determining the three-dimensional shape formed in the magnetic field surface induction unit (100), but it is difficult to infer the three-dimensional shape formed in the magnetic field surface induction unit (100) after determining the three-dimensional shape shown in the printed result.

[0168] That is, the three-dimensional shape or domain to be formed in the magnetic field surface induction unit (100), the magnetic field rear induction unit (300), or the magnetic field application unit (200) can be produced through complex calculations.

[0169] These calculations can be used for numerical analysis such as multiple regression analysis, or for instrumental learning.

[0170] Using software that programs these calculations, it is possible to design a three-dimensional shape or magnetic domain to be formed in the magnetic field surface induction unit (100), the magnetic field rear induction unit (300), or the magnetic field application unit (200).

[0171] The present invention is not limited to the above-described embodiments, and the scope of application is diverse, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
