Description

Technical Field

[0001] The present application relates to the technical field of 3D anti-counterfeiting printing, and in particular to a printing method and a printing device. Background Art

[0002] In the prior art, various commodities need to be printed with corresponding anti-counterfeiting patterns to prevent others from counterfeiting and selling the commodities. For example, a printed pattern with anti-counterfeiting ability that is difficult to counterfeit can be set on the commodities, so that even if others can counterfeit the commodities, it is difficult to set the printed pattern on the counterfeit commodities, so that buyers can determine whether the commodities are genuine by whether the printed pattern exists on the commodities.

[0003] The defect of the prior art is that, with respect to the existing printed patterns with anti-counterfeiting capabilities, the complexity of the lines of the printed patterns is increased to increase the difficulty of counterfeiting the printed patterns, but this will also make it difficult for buyers to determine whether the more complex patterns they see are genuine printed patterns, that is, the recognition of the printed patterns is poor. Alternatively, the complexity of the lines of the printed patterns is reduced to increase the recognition of the printed patterns, but this will also make the difficulty of counterfeiting the printed patterns lower. In other words, the printed patterns of the prior art are difficult to have both the characteristics of high recognition and high difficulty of counterfeiting, and have poor anti-counterfeiting capabilities. Summary of the invention

[0004] The main technical problem solved by this application is how to improve the anti-counterfeiting ability of printed patterns.

[0005] In order to solve the above technical problems, the first technical solution adopted in this application is: a printing method, comprising: applying magnetic ink to a substrate so that the magnetic ink is located on one side of the substrate; placing a hexagonal magnetic member on the other side of the substrate; the projection shape of the hexagonal magnetic member in the first direction is a hexagon, the first direction is the direction from the hexagonal magnetic member toward the substrate, the magnetic field direction of the hexagonal magnetic member is a second direction, and the second direction is not parallel to the first direction; and curing the magnetic ink.

[0006] The hexagon is a symmetrical hexagon, or the hexagon is a regular hexagon.

[0007] The hexagon is a regular hexagon, the length of any side of the hexagon is a first value, the thickness of the hexagonal magnetic part in the first direction is a second value, and the ratio between the first value and the second value is 0.1-10.

[0008] The second direction is perpendicular to the first direction.

[0009] Placing the hexagonal magnetic piece on the other side of the substrate includes: magnetically connecting at least one hexagonal magnetic piece and / or magnetic piece in a second direction to form a splicing piece; the second direction is perpendicular to the first direction; and placing the splicing piece on the other side of the substrate.

[0010] Wherein, the projection shape of the splicing piece in the first direction is a symmetrical figure.

[0011] Wherein, the magnetic field strength of the hexagonal magnetic member is not less than 200 millitesla, and / or, when the hexagonal magnetic member is located on the other side of the substrate, the distance between the hexagonal magnetic member and the substrate is not greater than 100 mm.

[0012] The hexagon includes a first side and a second side, and the first side is different from the second side.

[0013] The first side and the second side are both straight sides, and the length of the first side is different from the length of the second side; or, the first side is a straight side, and the second side is a curved side.

[0014] In order to solve the above technical problems, the second technical solution adopted in this application is: 10. A printing device, comprising: at least one hexagonal magnetic member, the projection shape of the hexagonal magnetic member in the first direction is a hexagon, the magnetic field direction of the hexagonal magnetic member is a second direction, and the second direction is not parallel to the first direction; the first direction is the direction from the hexagonal magnetic member toward the substrate to be printed.

[0015] The beneficial effects of the present application are as follows: Different from the prior art, in the technical solution of the present application, the magnetic ink is coated on the substrate so that the magnetic ink is located on one side of the substrate; the hexagonal magnetic member is placed on the other side of the substrate; the magnetic ink is cured; the projection shape of the hexagonal magnetic member in the first direction is a hexagon, the first direction is the direction from the hexagonal magnetic member toward the substrate, the magnetic field direction of the hexagonal magnetic member is the second direction, and the second direction is not parallel to the first direction. Based on the above method, the magnetic pigment ink composition on the uncured substrate can be magnetically acted on based on the hexagonal magnetic member with a projection shape of a hexagon, so that the magnetic pigment ink The magnetic particles in the composition are arranged and adjusted under the influence of the corresponding magnetic field, so that the pattern formed by the magnetic pigment ink composition has the effect of being large in the middle and small at both ends, and the pattern changes with the viewing angle. The magnetic pigment ink composition is then cured to fix the pattern to form the desired printed pattern. That is, when using the hexagonal magnetic member with a relatively simple structure, a printed pattern with the characteristics of being large in the middle and small at both ends, and the color changing effect with the viewing angle can be achieved. Since this characteristic is more obvious, the printed pattern has a high degree of recognition and is difficult to imitate, thereby improving the anti-counterfeiting ability of the printed pattern.

[0055] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application.

[0056] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0057] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "set", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium. For ordinary technicians in this field, the above-mentioned specific meanings belonging to this application can be connected according to specific circumstances.

[0058] This application proposes a printing method, see Figure 1 , Figure 1 : is a schematic diagram of a process of an embodiment of the printing method of the present application. Figure 1 As shown, the printing method includes:

[0059] Step S11 : coating the magnetic ink 11 onto the substrate 12 , so that the magnetic ink 11 is located on one side of the substrate 12 .

[0060] The magnetic ink 11 may be magnetic optically color-changing ink or other types of magnetic ink, which is not limited here.

[0061] See also Figure 2 , Figure 2 Schematic diagram of the spatial structure of magnetic ink, substrate and hexagonal magnetic components in the printing process of this application. Figure 2 As shown, the uncured magnetic ink 11 can be output to the upper side of the substrate 12 to achieve coating of the magnetic ink 11.

[0062] In one example, the substrate 12 may be placed on an operating platform first.

[0063] A preset mold is then placed on the substrate 12. The preset mold has a hollow area. The shape of the hollow area can be any desired shape of the printed pattern. After subsequent curing, the edge shape of the printed pattern will correspond to the shape of the hollow area, which is not limited here.

[0064] Then, the magnetic ink 11 is output to the hollow area, so that the magnetic ink 11 fills the hollow area, and the coating of the magnetic ink 11 is completed.

[0065] Step S12 : placing the hexagonal magnetic member 13 on the other side of the substrate 12 .

[0066] The magnetic ink 11 can be magnetized based on step S12.

[0067] The projection shape of the hexagonal magnetic component 13 in the first direction is a hexagon. The first direction is the direction from the hexagonal magnetic component 13 toward the substrate 12, and may also refer to the projection direction of the positive projection of the hexagonal magnetic component 13 on the substrate 12. The magnetic field direction of the hexagonal magnetic component 13 is the second direction, and the second direction is not parallel to the first direction.

[0068] In an example, the first direction may specifically refer to a vertical direction parallel to the gravity direction, and the second direction may refer to a horizontal direction perpendicular to the vertical direction, that is, a direction on a horizontal plane.

[0069] A hexagonal magnetic piece 13 can be set on the side of the operating platform away from the substrate 12, so that the magnetic ink 11 on the substrate 12 is subjected to a corresponding magnetic field based on the hexagonal magnetic piece 13, so that the magnetic particles in the magnetic ink 11 are arranged and adjusted under the action of the corresponding magnetic field, so that the pattern formed by the magnetic ink 11 has a large middle and small ends, and the pattern changes with the change of viewing angle. It should be noted that the effect of the pattern change can be a color change, a change in the depth of black, white and gray, or other types of pattern change effects, which can be determined according to the type of magnetic ink 11 used, and is not limited here.

[0070] Step S13: curing the magnetic ink 11.

[0071] After the magnetization in step S12 , step S13 may be performed to solidify the magnetic ink 11 .

[0072] After the pattern formed by the magnetic ink 11 has the effect characteristics of being large in the middle and small at both ends, and the pattern changes with changes in viewing angle, the magnetic ink 11 can be cured to form a printed pattern that is fixed and no longer changes with changes in the surrounding magnetic field. That is, the cured printed pattern will maintain the effect characteristics of being large in the middle and small at both ends, and the pattern changes with changes in viewing angle under the action of any magnetic field, thereby completing the printing operation and improving the anti-counterfeiting ability of the printed pattern.

[0073] In one example, the magnetic ink 11 in the hollow area can be solidified so that the edge shape of the printed pattern corresponds to the shape of the hollow area, and the distribution of the printed pattern itself will also have the characteristics of being large in the middle and small at both ends. Subsequently, the magnetic ink is solidified to fix the pattern and a printed pattern formed by the solidified magnetic ink 11 can be obtained.

[0074] Different from the prior art, in the technical solution of the present application, the magnetic ink is coated on the substrate so that the magnetic ink is located on one side of the substrate; the hexagonal magnetic member is placed on the other side of the substrate; the magnetic ink is cured; the projection shape of the hexagonal magnetic member in the first direction is a hexagon, the first direction is the direction from the hexagonal magnetic member toward the substrate, the magnetic field direction of the hexagonal magnetic member is the second direction, and the second direction is not parallel to the first direction. Based on the above method, the magnetic pigment ink composition on the uncured substrate can be magnetically acted on the hexagonal magnetic member with a projection shape of a hexagon, so that the magnetic pigment ink composition in the magnetic pigment ink composition The magnetic particles are arranged and adjusted under the influence of the corresponding magnetic field so that the pattern formed by the magnetic pigment ink composition has the effect characteristics of being large in the middle and small at both ends, and the pattern changes with the change of viewing angle. The magnetic pigment ink composition is subsequently cured to fix the pattern to form the desired printed pattern. That is, when using the hexagonal magnetic member with a relatively simple structure, a printed pattern with the characteristics of being large in the middle and small at both ends, and the color changing effect with the change of viewing angle can be achieved. Since this characteristic is more obvious, the printed pattern has a high degree of recognition and is difficult to imitate, thereby improving the anti-counterfeiting ability of the printed pattern.

[0075] In summary, the printing method provided in the present application provides a new method for manufacturing anti-counterfeiting patterns. The patterns prepared based on this printing method have the characteristics of being "easy to identify and difficult to imitate", and also have a certain aesthetic effect, thereby achieving improvements in anti-counterfeiting technology.

[0076] In one embodiment, the second direction is perpendicular to the first direction.

[0077] Specifically, the first direction refers to a vertical direction parallel to the gravity direction, and the second direction is a horizontal direction perpendicular to the vertical direction, that is, a direction on a horizontal plane.

[0078] In the second direction, that is, when the magnetic field direction of the hexagonal magnetic member 13 is horizontal, the magnetic field of the hexagonal magnetic member 13 has the strongest effect on the magnetic field of the magnetic ink 11 on the substrate 12, and can produce the best printing pattern effect, further improving the anti-counterfeiting ability of the printed pattern.

[0079] In one embodiment, the hexagon is a symmetrical hexagon, or the hexagon is a regular hexagon.

[0080] Specifically, the viewing angle when the observer's line of sight is perpendicular to the plane where the printed pattern is located is defined as 0 degrees, and the viewing angle when the observer's line of sight is parallel to the plane where the printed pattern is located is defined as 90 degrees. When the observer's viewing angle is 0 degrees, the shape of the hexagonal magnetic member 13 observed is the above-mentioned projection shape, which can be a symmetrical hexagon or a regular hexagon.

[0081] In one example, see Figure 3 , Figure 3 : is a schematic structural diagram of the first embodiment of the hexagonal magnetic member of the present application, such as Figure 3 As shown, the projection shape of the hexagonal magnetic member 13 in the first direction is a regular hexagon, and the second direction is perpendicular to the first direction, that is, the second direction is a horizontal direction, and the second direction is parallel to one side of the projection shape of the regular hexagon. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0082] See also Figures 4 to 6 , Figure 4 This is a multi-view effect diagram of the first embodiment of the printed pattern of the present application on the magnetic field. Figure 5 This is one of the multi-view effect diagrams of the first embodiment of the printed pattern of the present application on the pattern. Figure 6 This is the second multi-view pattern effect diagram of the first embodiment of the printed pattern of the present application.

[0083] like Figure 4 As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that there is always a bright bar in the middle of the printed pattern, and the brightness gradually decreases until it becomes dark on both sides. As the viewing angle changes, the bright bar gradually changes from a straight line to a curve, and is always located in the middle of the printed pattern, giving the illusion of rolling.

[0084] like Figure 5 and Figure 6 As shown in FIG. 1 , the corresponding situation of the printed pattern when the hollow area is other shapes, the hollow area only affects the edge shape of the printed pattern, but the color change in the printed pattern is still the same as Figure 4 Corresponding.

[0085] In another example, see Figure 7 , Figure 7 : is a schematic diagram of the structure of the second embodiment of the hexagonal magnetic member of the present application. Figure 7 As shown, the projection shape of the hexagonal magnetic member 13 in the first direction is a regular hexagon, and the second direction is perpendicular to the first direction, that is, the second direction is a horizontal direction, and the second direction is perpendicular to one side of the projection shape of the regular hexagon. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0086] See also Figures 8 to 10 , Figure 8 This is a multi-view effect diagram of the second embodiment of the printed pattern of the present application on the magnetic field. Fig. 9 This is one of the multi-view effect diagrams of the second embodiment of the printed pattern of the present application on the pattern. Fig.10 This is the second multi-viewing effect diagram of the second embodiment of the printed pattern of the present application.

[0087] like Figure 8 As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that with the change of viewing angle, the bright strips gradually become thinner, and finally the far end is completely dark, while the near end is still bright, giving the illusion of rolling.

[0088] like Fig. 9 and Fig.10 As shown in FIG. 1 , the corresponding situation of the printed pattern when the hollow area is other shapes, the hollow area only affects the edge shape of the printed pattern, but the color change in the printed pattern is still the same as Figure 8 Corresponding.

[0089] In other examples, the magnetic field direction of the hexagonal magnetic member 13 having the projection shape of a regular hexagon may be a horizontal direction that forms an angle greater than 0 degrees and less than 90 degrees with one side of the regular hexagon, which is not limited here.

[0090] Optionally, the hexagon is a regular hexagon, the length of any side of the hexagon is a first value, the thickness of the hexagonal magnetic member 13 in the first direction is a second value, and the ratio between the first value and the second value is 0.1-10.

[0091] Specifically, the ratio between the first value and the second value can be 2, that is, the length of any side of the hexagon is twice the thickness. The magnetic field formed by the hexagonal magnetic member 13 under this ratio can better exert a magnetic field effect on the magnetic ink 11. If the ratio between the first value and the second value is too large, it is easy to cause the magnetic field effect on the unit area of ​​the magnetic ink 11 to be too weak. If the ratio between the first value and the second value is too small, it is easy to cause the magnetic field effect on the unit area of ​​the magnetic ink 11 to be too strong. When the ratio between the first value and the second value is 2, the magnetic ink 11 can be subjected to a more appropriate magnetic field effect at every place as much as possible to improve the effect of the printed pattern. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0092] In one embodiment, the hexagon includes a first side and a second side, and the first side is different from the second side.

[0093] Specifically, while maintaining the symmetry of the hexagon, the difference between the first side and the second side may be that one is a straight side and the other is a curved side, or one is a long side and the other is a short side.

[0094] The first side and the second side may be two adjacent sides or two opposite sides, which is not limited here.

[0095] Based on the above method, the magnetic ink 11 can be subjected to a magnetic field effect through a hexagonal magnetic member 13 having a symmetrical hexagonal projection shape, and the printed pattern can have a corresponding deformation effect on the basis of being large in the middle and small at both ends, and having a color change effect with changes in viewing angle. For example, the size difference between the middle section and the two end sections of a bright strip that is large in the middle and small at both ends can be increased or decreased, or the bright strip that is large in the middle and small at both ends can be extended along a straight line or along a curve, which changes specifically according to the side length characteristics of the hexagon and the change in the second direction, which is not limited here.

[0096] Optionally, the first side and the second side are both straight sides, and the length of the first side is different from the length of the second side.

[0097] Alternatively, the first side is straight and the second side is curved.

[0098] Specifically, in the first example, see Figure 11 to Figure 12 , Fig.11 : is a schematic structural diagram of the third embodiment of the hexagonal magnetic member of the present application, Fig.12 This is a multi-viewing effect diagram of the third embodiment of the printed pattern of the present application.

[0099] like Fig.11 As shown, each side in the hexagon is a straight side, there are two groups of relatively short sides and one group of relatively long sides in the hexagon, and the second direction is perpendicular to the first direction, that is, the second direction is horizontal, and the second direction is perpendicular to the long sides.

[0100] like Fig.12 As shown, from top to bottom are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that there is always a bright bar in the middle of the printed pattern, and the brightness gradually decreases until it becomes dark on both sides. As the viewing angle changes, the bright bar gradually changes from a straight line to a curved line, giving the illusion of rolling.

[0101] In the second example, see Figure 13 to Figure 14 , Fig.13 : is a schematic structural diagram of the fourth embodiment of the hexagonal magnetic member of the present application, Fig.14 This is a multi-viewing effect diagram of the fourth embodiment of the printed pattern of the present application.

[0102] like Fig.13As shown, each side in the hexagon is a straight side, there are two sets of long sides and one set of short sides in the hexagon, the second direction is perpendicular to the first direction, that is, the second direction is horizontal, and the second direction is perpendicular to the short side. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0103] like Fig.14 As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that there is always a bright bar in the middle of the printed pattern, and as the viewing angle changes, the bright bar gradually changes from a straight line to a curved line, giving the illusion of rolling.

[0104] In the third example, see Figure 15 to Figure 16 , Fig.15 is a schematic structural diagram of the fifth embodiment of the hexagonal magnetic member of the present application, Fig.16 This is a multi-viewing effect diagram of the fifth embodiment of the printed pattern of the present application.

[0105] like Fig.15 As shown, each side in the hexagon is a straight side, there are two sets of short sides and one set of long sides in the hexagon, the second direction is perpendicular to the first direction, that is, the second direction is horizontal, and the second direction is parallel to the long side. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0106] like Fig.16 As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that there is always a bright bar in the middle of the printed pattern, and as the viewing angle changes, the bright bar gradually changes from being distributed along a straight line to being distributed along a curved line, giving the illusion of rolling.

[0107] In the fourth example, see Figure 17 to Figure 18 , Fig.17 is a schematic structural diagram of the sixth embodiment of the hexagonal magnetic member of the present application, Fig.18 This is a multi-viewing effect diagram of the sixth embodiment of the printed pattern of the present application.

[0108] like Fig.17 As shown, each side in the hexagon is a straight side, there are two sets of long sides and one set of short sides in the hexagon, the second direction is perpendicular to the first direction, that is, the second direction is horizontal, and the second direction is parallel to the short side. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0109] like Fig.18As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that there is always a bright strip in the middle of the printed pattern, which is thick in the middle, thin at both ends, and finally radial patterns appear at both ends. As the viewing angle changes, the bright strip gradually changes from being distributed along a straight line to being distributed along a curved line, giving the illusion of rolling.

[0110] In the fifth example, see Figures 19 to 20 , Fig.19 : is a schematic structural diagram of the seventh embodiment of the hexagonal magnetic member of the present application, Fig. 20 This is a multi-viewing effect diagram of the seventh embodiment of the printed pattern of the present application.

[0111] like Fig.19 As shown, each side in the hexagon is a straight side, and there are three sets of long sides and short sides arranged oppositely in the hexagon, and the long sides and short sides are connected alternately in sequence, and the second direction is perpendicular to the first direction, that is, the second direction is a horizontal direction, and the second direction is perpendicular to a long side. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0112] like Fig. 20 As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 45 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of -30 degrees, and the printed pattern observed by the observer at a viewing angle of -45 degrees. It can be seen that in the process from 0 degrees to 45 degrees, or from 0 degrees to -45 degrees, there is always a bright bar in the middle of the printed pattern, and the brightness gradually decreases until it becomes dark towards both sides, and as the viewing angle changes, the bright bar gradually changes from a straight line to a curved line, giving the illusion of rolling.

[0113] In the sixth example, see Figure 21 to Figure 22 , Fig.21 is a schematic structural diagram of the eighth embodiment of the hexagonal magnetic member of the present application, Fig. 22 This is a multi-viewing effect diagram of the eighth embodiment of the printed pattern of the present application.

[0114] like Fig.21 As shown, each side in the hexagon is a straight side, there are two groups of short sides and one group of long sides in the hexagon, the second direction is perpendicular to the first direction, that is, the second direction is horizontal, and the second direction is perpendicular to one short side. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13. It can be seen that the midpoint between the N pole and the S pole of the hexagonal magnetic member 13 is parallel to one of the short sides, that is, the second direction representing the direction of the magnetic field is perpendicular to one of the short sides.

[0115] like Fig. 22 As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that this embodiment is different from the above embodiments: the middle is large and the two ends are small. The two ends of this embodiment are also thinner and the middle is also large, but a certain degree of distortion occurs. Therefore, there is an S-shaped bright strip in the middle of the printed pattern, and the brightness of the middle section of the S-shaped bright strip gradually decreases until it becomes dark toward both sides, and as the viewing angle changes, the S-shaped bright strip gradually changes from a straight line to a curved thin line, giving the illusion of rolling.

[0116] In the seventh example, see Figure 23 to Figure 24 , Fig.23 is a schematic structural diagram of the ninth embodiment of the hexagonal magnetic member of the present application, Fig.24 This is a multi-viewing effect diagram of the ninth embodiment of the printed pattern of the present application.

[0117] like Fig.23 As shown, each side in the hexagon is a straight side, there are two groups of short sides and one group of long sides in the hexagon, the second direction is perpendicular to the first direction, that is, the second direction is horizontal, and the second direction is parallel to one short side. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13. It can be seen that the midpoint between the N pole and the S pole of the hexagonal magnetic member 13 is perpendicular to one of the short sides, that is, the second direction representing the direction of the magnetic field is parallel to one of the short sides.

[0118] like Fig.24 As shown, from left to right are the printed pattern observed by the observer at a viewing angle of 0 degrees, the printed pattern observed by the observer at a viewing angle of 30 degrees, and the printed pattern observed by the observer at a viewing angle of 45 degrees. It can be seen that this embodiment is similar to the previous embodiment, but different: because of the magnet isomerism, the bright strip has a certain distortion, there is always an S-shaped bright strip in the middle of the printed pattern, and the brightness of the middle section of the S-shaped bright strip gradually decreases until it becomes dark on both sides, and as the viewing angle changes, the S-shaped bright strip gradually changes from a straight line to a curved line, giving the illusion of rolling.

[0119] In the eighth example, see Fig.25 , Fig.25 is a schematic structural diagram of the tenth embodiment of the hexagonal magnetic member of the present application, such as Fig.25 As shown, the symmetrical hexagon can also be a hexagon with other combinations of long and short straight sides, which is not limited here.

[0120] In the ninth example, see Fig.26 , Fig.26 is a schematic structural diagram of the eleventh embodiment of the hexagonal magnetic member of the present application, such as Fig.26 As shown, the symmetrical hexagon can also be a hexagon with other combinations of long and short straight sides and long and short curved sides, which is not limited here.

[0121] In the tenth example, see Fig. 27 , Fig. 27 is a schematic structural diagram of the twelfth embodiment of the hexagonal magnetic member of the present application, such as Fig. 27 As shown, the symmetrical hexagon may also have a hollow area, which is not limited here.

[0122] In one embodiment, the hexagonal magnetic member 13 is placed on the other side of the substrate 12, including:

[0123] At least one hexagonal magnetic member 13 and / or magnetic members are magnetically connected in a second direction (by magnetic attraction) to form a spliced ​​piece, wherein the second direction is perpendicular to the first direction.

[0124] The splicing piece is placed on the other side of the substrate 12.

[0125] Specifically, the projection shape of the splicing piece in the first direction is a symmetrical figure.

[0126] The first direction is parallel to the gravity direction, the second direction is perpendicular to the first direction, and the second direction is a horizontal direction.

[0127] The magnetic member may be made of a magnetic material, such as iron or other magnetic materials, which is not limited here.

[0128] A plurality of hexagonal magnetic members 13, or a plurality of hexagonal magnetic members 13 and magnetic members, can be magnetically connected in each second direction (by means of magnetic attraction) to form a spliced ​​member, so that a plurality of elements of the pattern produced by a single hexagonal magnetic member 13 can be simultaneously present in the printed pattern, thereby providing more solutions, further increasing the difficulty of counterfeiting, and improving the anti-counterfeiting capability.

[0129] In the first example, see Figure 28 to Figure 29 , Fig.28 is a schematic structural diagram of the thirteenth embodiment of the hexagonal magnetic member of the present application, Fig.29 This is a multi-view effect diagram of the thirteenth embodiment of the printed pattern of the present application. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0130] like Fig.28 As shown, the splicing piece is formed by splicing (using magnetic attraction) a plurality of hexagonal magnetic pieces 13 and a magnetic piece located in the center, as shown in FIG. Fig.29 As shown, the printed pattern is formed by merging the patterns produced by the influence of multiple single hexagonal magnetic members 13 .

[0131] In the second example, see Figure 30 to Figure 31 , Fig.30 is a schematic structural diagram of the fourteenth embodiment of the hexagonal magnetic member of the present application, Fig.31 This is a multi-view effect diagram of the fourteenth embodiment of the printed pattern of the present application. Fig.30 As shown, the splicing piece is formed by splicing a plurality of hexagonal magnetic pieces 13 (by magnetic attraction), as shown in FIG. Fig.31 As shown, the printed pattern is formed by the fusion of the patterns generated by the influence of multiple hexagonal magnetic parts 13. In the figure, N is the N pole of the hexagonal magnetic part 13, S is the S pole of the hexagonal magnetic part 13, and M is a magnetic material (magnetic material) with the same volume and shape as the hexagonal magnetic part 13, such as iron, cobalt, nickel and other magnetic materials, and alloys composed of at least one of iron, cobalt, nickel and other magnetic materials.

[0132] In the third example, see Figure 32 to Figure 33 , Fig.32 is a schematic structural diagram of the fifteenth embodiment of the hexagonal magnetic member of the present application, Fig.33 This is a multi-view effect diagram of the fifteenth embodiment of the printed pattern of the present application. Fig.32 As shown, the splicing piece is formed by splicing two hexagonal magnetic pieces 13 and magnetic pieces (using magnetic attraction), as shown in FIG. Fig.33 As shown, the printed pattern is formed by the fusion of two patterns generated by a single hexagonal magnetic member 13 and the magnetic member. In the figure, N is the N pole of the hexagonal magnetic member 13, S is the S pole of the hexagonal magnetic member 13, and M is a magnetic material (magnetic material) with the same volume and shape as the hexagonal magnetic member 13, such as iron, cobalt, nickel and other magnetic materials, and alloys composed of at least one of iron, cobalt, nickel and other magnetic materials.

[0133] like Fig.33 As shown, from left to right, the printed patterns are observed at viewing angles of 0 degrees, 30 degrees, and 45 degrees respectively. It can be seen that there is an "S"-shaped dividing line in the middle of the pattern, which divides the pattern into two centrally symmetrical halves, and a "yin and yang" effect occurs, that is: as the viewing angle increases, the near end gradually darkens until it becomes black, and on the contrary, the brightness of the far end gradually increases, but the "S"-shaped dividing line in the middle does not change.

[0134] In the fourth example, see Fig.34 , Fig.34 is a schematic structural diagram of the sixteenth embodiment of the hexagonal magnetic member of the present application, such as Fig.34As shown, the splicing piece can also be spliced ​​by two or more hexagonal magnetic pieces 13 and magnetic pieces of other types (using magnetic attraction), which is not limited here. In the figure, N is the N pole of the hexagonal magnetic piece 13, S is the S pole of the hexagonal magnetic piece 13, and M is a magnetic material (magnetic material) with the same volume and shape as the hexagonal magnetic piece 13, or a magnetic material with different volume and shape, such as iron, cobalt, nickel and other magnetic materials, and alloys composed of at least one of iron, cobalt, nickel and other magnetic materials.

[0135] In the fifth example, see Figure 35 to Figure 36 , Fig.35 is a structural schematic diagram of the seventeenth embodiment of the hexagonal magnetic member of the present application, Fig.36 17 is a multi-view effect diagram of the seventeenth embodiment of the printed pattern of the present application. Fig.35 As shown, the splicing piece is formed by splicing two hexagonal magnetic pieces 13 (by magnetic attraction). It can be seen that the second directions corresponding to the two hexagonal magnetic pieces 13 are at an angle of 60° on the horizontal plane. Fig.36 As shown, the printed pattern is composed of two patterns produced by the influence of a single hexagonal magnetic member 13. It can be seen that the pattern presents an effect similar to a flying bird or an airplane. In the figure, N is the N pole of the hexagonal magnetic member 13, and S is the S pole of the hexagonal magnetic member 13.

[0136] In the sixth example, see Fig.37 , Fig.37 is a schematic structural diagram of the eighteenth embodiment of the hexagonal magnetic member of the present application, such as Fig.37 As shown, the splicing piece can also be spliced ​​by two or more hexagonal magnetic pieces 13 of other types, which is not limited here. In the figure, N is the N pole of the hexagonal magnetic piece 13, and S is the S pole of the hexagonal magnetic piece 13.

[0137] It should be noted that the above are all examples, which can be adaptively adjusted in practice and are not limited here.

[0138] In one embodiment, the magnetic field strength of the hexagonal magnetic member 13 is not less than 200 millitesla, and / or, when the hexagonal magnetic member 13 is located on the other side of the substrate 12, the distance between the hexagonal magnetic member 13 and the substrate 12 is not greater than 100 mm.

[0139] Specifically, by ensuring that the magnetic field strength of the hexagonal magnetic member 13 is not less than 200 milliteslas, and / or, when the hexagonal magnetic member 13 is located on the other side of the substrate 12 away from the magnetic ink 11, the distance between the hexagonal magnetic member 13 and the substrate 12 is not greater than 100 mm, the strength of the magnetic field applied by the hexagonal magnetic member 13 to the magnetic ink 11 can be increased, thereby improving the color change effect of the printed pattern with changes in viewing angle, and further improving the recognition of the printed pattern.

[0140] The present application also provides a printing device, which includes at least one hexagonal magnetic member 13 .

[0141] The projection shape of the hexagonal magnetic member 13 in the first direction is a hexagon, and the magnetic field direction of the hexagonal magnetic member 13 is a second direction, which is not parallel to the first direction.

[0142] The first direction is the direction from the hexagonal magnetic member 13 toward the substrate 12 to be printed.

[0143] Specifically, the hexagonal magnetic member 13 may be the hexagonal magnetic member 13 described in any of the above embodiments, which will not be described in detail here.

[0144] Different from the prior art, in the technical solution of the present application, the magnetic ink is coated on the substrate so that the magnetic ink is located on one side of the substrate; the hexagonal magnetic member is placed on the other side of the substrate; the magnetic ink is cured; the projection shape of the hexagonal magnetic member in the first direction is a hexagon, the first direction is the direction from the hexagonal magnetic member toward the substrate, the magnetic field direction of the hexagonal magnetic member is the second direction, and the second direction is not parallel to the first direction. Based on the above method, the magnetic pigment ink composition on the uncured substrate can be magnetically acted on the hexagonal magnetic member with a projection shape of a hexagon, so that the magnetic pigment ink composition in the magnetic pigment ink composition The magnetic particles are arranged and adjusted under the influence of the corresponding magnetic field so that the pattern formed by the magnetic pigment ink composition has the effect characteristics of being large in the middle and small at both ends, and the pattern changes with the change of viewing angle. The magnetic pigment ink composition is subsequently cured to fix the pattern to form the desired printed pattern. That is, when using the hexagonal magnetic member with a relatively simple structure, a printed pattern with the characteristics of being large in the middle and small at both ends, and the color changing effect with the change of viewing angle can be achieved. Since this characteristic is more obvious, the printed pattern has a high degree of recognition and is difficult to imitate, thereby improving the anti-counterfeiting ability of the printed pattern.
