Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings in conjunction with specific examples.
First, specific technical terms used hereinafter will be briefly described. Hereinafter, reference to "composition elements" (e.g., a first type of composition elements and a second type of composition elements) refers to a minimum structural unit for forming a printed security pattern, the composition elements are arranged according to a certain rule (height rule and/or arrangement rule) so as to form the whole printed security pattern, and the composition elements are arranged according to a certain rule so as to form an overall pattern (such as a first pattern and a second pattern described below) in the printed security pattern, wherein the overall pattern can be shown from the printed security pattern when viewed in a certain viewing range.
Further, the "composition elements" of the present invention include different types of composition elements, and the different types mainly refer to whether the composition elements have coloring or not, or whether coloring is the same. For example, the first type of composition element hereinafter is a colored composition element, and the second type of composition element is an uncolored composition element. Of course, uncolored herein is merely a relative concept, except that the second type of composition element is not similarly colored with respect to the first type of composition element. If the substrate used to form the printed security pattern already has some coloration, then uncolored means that no further coloration has been applied to the substrate.
When the composition elements are arranged and distributed according to different rules, different graphic patterns can be formed. Some of the obvious patterns are formed by using the first type composition elements, and some of the obvious patterns are formed by simultaneously using the first type composition elements and the second type composition elements, and different pattern forming modes can result in different obvious modes and obvious effects. One or more of these graphic patterns may be formed in a printed security pattern. And these graphic patterns can be separated from each other, further, the graphic patterns superimposed on each other can be formed by using the composition elements, for this case, the setting rule of the composition elements in the superimposed part of the patterns will be more complicated than the setting rule for constructing a single graphic pattern, because the superimposed part needs to follow the setting rule of the composition elements in different graphic patterns at the same time, and at the same time, it is ensured that a good superimposed graphic effect is obtained.
The foregoing is a brief description of the basic technical terms used in the present invention and the underlying principles thereof, and the present invention will be described in detail below with reference to specific embodiments.
In a general embodiment, the printed anti-counterfeiting pattern comprises composition elements arranged according to a predetermined rule, and the composition elements comprise first type composition elements 11 and 12, specifically, the first type composition elements comprise first composition elements 11 with a first height and second composition elements 12 with a second height. The first and second patterning elements 11, 12 are arranged to cooperate to present a first pattern 10(ABC shown in figures 4a, 4 b) formed in the printed security pattern. Generally, the printed security pattern of the present invention may comprise only the first pattern 10, and in other embodiments, may comprise more than one other pattern in addition to the first pattern 10 formed as described above, which will be described in detail below with reference to exemplary embodiments.
Typically, the first pattern 10 has two different configurations, specifically including: first configuration (shown in fig. 4 a): in the region inside the first pattern 10, the first type patterning element is the first patterning element 11, and in the region outside the first pattern 10, the first type patterning element includes the first patterning element 11 and the second patterning element 12 which are alternately arranged (there is a height difference); or, conversely, the second configuration (shown in fig. 4 b): the first type patterning elements include first patterning elements 11 and second patterning elements 12 arranged alternately (with a height difference) in a region inside the first pattern 10, and the first type patterning elements are the first patterning elements 11 in a region outside the first pattern 10.
The two configurations described above make the first pattern 10 appear from the printed anti-counterfeiting pattern by forming a visual difference between the inside and outside of the first pattern 10 due to the height difference between the first composition element 11 and the second composition element 12 in the first observation state at a predetermined inclination angle.
Since a desired effect of the visualization can be obtained as long as the height difference exists, the first height may be set higher than the second height, or the second height may be set higher than the first height when the height of the first type composition element is set. The first pattern 10 is displayed due to the difference in height between the first composition element 11 and the second composition element 12 having different heights, and the composition elements having different heights may shield the line of sight to different degrees when viewed obliquely, so as to block the area behind the line of sight, thereby enabling the first pattern 10 to be displayed from the anti-counterfeit printing pattern. The appearance of the first pattern 10 is different as the viewing angle is tilted, e.g. the first pattern 10 appears from scratch and is most clear at a certain angle as the viewing angle is viewed from vertical to substantially horizontal, depending on the height difference between the first and second composition elements 11, 12. Specifically, as shown in fig. 4a, 4b, the first composition element 11 and the second composition element 12 are colored composition elements displayed to be different in shade.
It should be noted that the shades of the colors in fig. 4a and 4b are only areas with different heights, and the complete shape of the figure 10(ABC) can be distinguished by naked eyes or a two-dimensional microscope or a scanner only at a specific angle.
As noted above, in one exemplary embodiment of the present invention, the security print pattern may include a second pattern 20 in addition to the first pattern 10. Specifically, the composition elements of the printed anti-counterfeiting pattern further include a second type composition element 21, and the first type composition element 11 or 12 and the second type composition element 21 are arranged in a matching manner, so that a second pattern 20 formed in the printed anti-counterfeiting pattern is presented. Wherein the first type patterning elements 11 or 12 and the second type patterning elements 21 are arranged in a first rule in a region inside the second pattern 20, and the first type patterning elements 11 or 12 and the second type patterning elements 21 are arranged in a second rule different from the first rule in a region outside the second pattern 20. In this way, in the second observation state of perpendicular observation, the second pattern 20 is visually inferior in the inside and outside, and appears from the printed forgery-preventing pattern. The visual difference is a visual color difference due to the different arrangement of the composition elements inside and outside the second pattern 20. Specifically, as shown in fig. 5, the second composition element 21 is a composition element that is displayed as white uncolored.
Specifically, the arrangement rule for making the second pattern 20 appear will be explained. The first rule is that the first composition elements 11 of the first type (e.g., the first composition elements 11 and the second composition elements 21 of the second type are arranged in series, and the second rule is that the first composition elements 11 and the second composition elements 21 of the second type are arranged at intervals, the first composition elements 11 and the second composition elements 21 arranged in series form continuous colored regions and non-colored regions, and the first composition elements 11 and the second composition elements 21 arranged at intervals cannot form visually continuous colored regions and non-colored regions, so that when the anti-counterfeiting pattern is viewed, a color difference is formed between the inside and the outside of the first pattern 10, and the first pattern 10 can be clearly displayed.
In another embodiment, the above arrangement rule may be interchanged between the inside and the outside of the second pattern 20, wherein the first rule means that the first patterning elements 11 and the second type patterning elements 21 are arranged at intervals from each other, and the second rule means that the first patterning elements 11 and the second type patterning elements 21 are each respectively arranged consecutively. At this time, the second pattern 10 is formed with continuous colored regions and non-colored regions on the outside and is not formed with visually continuous colored regions and non-colored regions on the inside, but when the forgery-preventing pattern is viewed, a color difference is still formed between the inside and the outside of the second pattern 20, thereby allowing the first pattern 20 to be displayed.
Specifically, in the embodiments shown in fig. 7 to 10, the distribution densities of the first and second type patterning elements 11 and 21 inside (inside of the number 123) and outside (outside of the number 123) of the second pattern 20 are equivalent, but different regular arrangements are employed, thereby causing a visual color difference between the inner and outer regions of the second pattern 20. As clearly shown in fig. 8 to 9, the first composition elements 11 inside the number 123 are arranged continuously, while the first composition elements 11 outside the number 123 are arranged at intervals, and one second-type composition element 21 (uncolored portion) is disposed between two adjacent first composition elements 11. The above-described patterning makes it possible to form a color difference between the second pattern 20 as a whole and the region outside thereof.
Alternatively, in other embodiments according to the present invention, the first rule means that the first and second type composition elements 11 and 21 are distributed at a first distribution ratio, and the second rule means that the first and second type composition elements 11 and 21 are distributed at a second distribution ratio different from the first distribution ratio. That is, the distribution densities of the first and second type patterning elements 11 and 21 inside and outside the second pattern 20 are different, and the first distribution ratio may be large or the second distribution ratio may be large. For example, the distribution ratio of the first and second type composition elements 11 and 21 in the inner portion of the second pattern 20 is 2: 8, and the distribution ratio of the first and second type composition elements 11 and 21 in the outer portion is 7: 3, thereby forming a visual difference between the inner and outer portions of the second pattern 20.
As described above, in other embodiments, the distribution ratio of the first and second type composition elements 11 and 21 inside and outside the second pattern 20 may be made different, whereby the inside and outside of the second pattern 20 may also be made visually different in color. It should be noted that the element sizes of the first composition elements 11 and the second composition elements 21 are very small, and are in the order of μm, so that the second pattern 20 (numeral 123) can be displayed from the security pattern by macroscopically forming a visual color difference by arranging and combining the minute composition elements at different densities. For example, in one embodiment, the inside of the second pattern 20 has more uncolored regions than the outside, that is, the distribution density of the first patterning elements 11 inside the second pattern 20 is less than the distribution density of the first patterning elements 11 outside the second pattern 20, thereby making the entire area of the colored portion inside the second pattern 20 less than the entire area of the colored portion outside the second pattern 20, thereby making the above-described difference in inside and outside color.
In the above-described printed security pattern comprising two patterns, the first pattern 10 and the second pattern 20 appear simultaneously in an intermediate viewing state between the first viewing state (viewing at a specific oblique angle) and the second viewing state (viewing perpendicularly). Specifically, during the transition from the first observation state to the second observation state, the second pattern 20 gradually appears, and the first pattern 10 gradually disappears; during the transition from the second viewing state to the first viewing state, the first pattern 10 gradually appears and the second pattern 20 gradually disappears. In an embodiment of the present invention, the predetermined inclination angle is an inclination angle at which the angle of the line of sight with respect to the plane of distribution of the printed security pattern is approximately parallel. At the predetermined inclination angle, the second pattern 20 is clearly distinguished by visual color differences formed inside and outside the second pattern 20, and the first pattern 10 is hardly distinguished by the color difference effect in this state. Of course, in other embodiments according to the present invention, the predetermined inclination angle may be designed to be any other suitable angle, and is not limited to the specific angle in the above embodiments, as long as the desired visualization effect can be achieved. The design of the tilt angle is related to the height of the first and second patterning elements 11, 12 that are specifically used.
When the printed anti-counterfeiting pattern is vertically viewed, the second pattern 20 in the anti-counterfeiting pattern is shown, and the first pattern 10 is hidden; on the other hand, when the security pattern is viewed at an oblique angle, the first pattern 10 emerges from the security pattern due to the difference in height between the interior and exterior of the first pattern 10 (as best shown in fig. 7-10). In particular, the printed security pattern of the present invention may exhibit different visual effects when the oblique viewing angles are different, for example, when the security pattern is viewed at a small oblique angle, the first pattern 10 and the second pattern 20 in the security pattern are simultaneously displayed, and when the security pattern is viewed at a large oblique angle (for example, at an approximately horizontal angle), the first pattern 10 in the security pattern is completely displayed and the second pattern 20 cannot generate visual difference and is hidden.
According to the anti-counterfeiting pattern of the invention, the first pattern 10 and the second pattern 20 can be separately formed on the substrate layer 30. Furthermore, in an exemplary embodiment of the present invention, for a printed security pattern comprising a first pattern 10 and a second pattern 20, which patterns may further be superimposed, the construction of the security printed pattern is more complex, since the first type of composition elements of the superimposed portions need to follow specific rules. Specifically, in the overlapping region of the first pattern 10 and the second pattern 20, the first type patterning elements 11, 12 follow the height setting rule of the inner and outer regions of the first pattern 10, while following the arrangement rule of the inner and outer regions of the second pattern 20.
Fig. 1 to 3 show a schematic view of the visual effect of a printed security pattern according to an exemplary embodiment of the present invention (the first pattern 10 and the second pattern 20 are superimposed on each other) viewed at different angles, fig. 4a, 4b and 5 show a schematic view of the first pattern 10 and the second pattern 20 in the printed security pattern according to an exemplary embodiment of the present invention,
in an exemplary embodiment, the printed security pattern of the present invention is disposed on a substrate 30, the security pattern typically comprising a first pattern 10(ABC) and a second pattern 20(123), the first pattern 10 being constituted by first and/or second patterning elements 11, 12, and the second pattern 20 being constituted by first or second patterning elements 11, 12 and a second type of patterning element 21. In the present embodiment, the second height is set higher than the first height, that is, the second patterning element 12 is higher than the first patterning element 11, and the outer portion of the first pattern 10 includes only the first patterning element 11 (i.e., follows the second configuration).
In the present embodiment, in the first observation state of oblique observation, a visual difference is formed between the inside and the outside of the first pattern 10, and the second composition element 12 forms a blocking effect on the first composition element 11 and the second type composition element 21, so that a visual difference is generated between a region (inside the first pattern 10) including the second composition element 12 and a region (outside the first pattern 10) including only the first composition element 11, that is, the visual difference is generated by a height difference of the first type composition elements having different heights.
Specifically, in order to ensure the effect of the first pattern 10, the first height and the second height are set within a certain range, so that there is a proper height difference therebetween, on one hand, the height difference is not too small to prevent the first pattern 10 from exhibiting a good appearance effect when the security pattern is obliquely observed, and on the other hand, the height difference is not too large to allow the second pattern 20 to be directly exhibited due to an excessive height difference when the security pattern is vertically observed. Optionally, the first height is greater than 1 μm and the second height is not less than the first height, or conversely, the second height is greater than 1 μm and the first height is not less than the second height.
It should be noted that when the first pattern 10 is overlapped with the second pattern 20, the second-type composition elements 21 in the second pattern 20 still remain (the non-coloring elements are not covered), that is, the first- type composition elements 11 and 12 in the first pattern 10 are not overlapped on the second-type composition elements 21 in this portion. This is done to ensure that the first pattern 10 does not affect the appearance of the second pattern 20, i.e. if the superimposed first pattern 10 covers the second type of pattern elements 21 in the second pattern 20, the second pattern 20 is difficult to be color-shifted from the areas outside it, so that the second pattern 20 is difficult to be revealed from the security pattern.
As shown in fig. 8 and 9, the first type of patterning elements 11 and 12 of the printed anti-counterfeiting pattern can be blocks with square cross sections, and the square blocks are distributed at uniform intervals according to the first rule or the second rule. Of course, in other embodiments, the first type patterning elements 11, 12 may also be blocks having a circular, rectangular, or other type of polygonal cross-section. Preferably, the side length or the diameter of the first type patterning elements 11, 12 may be set to be greater than 2 μm.
The method of making the printed security pattern according to the present invention will now be described with continued reference to the accompanying drawings. The method for manufacturing the printed anti-counterfeiting pattern mainly comprises the following steps: designing and printing anti-counterfeiting patterns; making a plate based on the anti-counterfeiting pattern; and utilizing the prepared printing plate to make anti-counterfeiting patterns. The finished security pattern comprises a first pattern 10 and a second pattern 20 disposed on a substrate 30.
According to the method of the present invention, in an embodiment, in the step of performing plate making based on the printed anti-counterfeiting pattern, the plate making is film plate making, and the method includes: outputting a design pattern 40 (shown in fig. 10) comprising a printed security pattern to the film; and then using the film with the design pattern to make an original plate or a printing plate through plate etching. In the film formed by the design pattern 40, a screening structure is designed at a position on the film for forming the first patterning element 11 of the first height (as shown in fig. 11 a), and a solid structure is designed at a position for forming the first patterning element 12 of the second height (as shown in fig. 11 b). Or, on the contrary, the film is designed to be a solid structure at the position for forming the second pattern element 12 and to be a screening structure at the position for forming the first pattern element 11. In particular, the screening structure is a mesh fabric lattice structure, a transverse line, a dot structure and the like.
Fig. 11a shows a first patterning element 11 having a screening structure for forming a first patterning unit 11 of a first height, and fig. 11b shows a second patterning element 12 having a solid structure for forming a second patterning unit 12 of a second height, by which the first patterning element 11 having a cloth-check structure will have a shallower depth and the second patterning element 12 having a solid structure will have a deeper depth during subsequent production of the transfer plate, so that a first type of patterning element having a different height can be formed during subsequent production.
Furthermore, the locations on the film for forming the first patterning elements 11 at the first level may be designed as a first type of screening structure and the locations for forming the second patterning elements 12 at the second level as a second type of screening structure. The first type of patterning elements can also be made with different heights using different screening structures.
After design pattern 40 is well designed and corresponding blueprint film is made by utilizing design pattern 40, the anti-counterfeiting pattern can be printed by utilizing blueprint corrosion process, which comprises the following steps: and (4) utilizing the prepared printing film to prepare an original plate or a printing plate. Wherein, the depth of the first pattern elements 11 with the screening structure is the same, about 10 μm-30 μm (principle: microstructure is the same, arrangement is different), while the depth of the second pattern elements 12 with the solid structure is as deep as possible, such as 20 μm-50 μm, the manufactured original plate or printing plate is processed and then is printed on the machine to finish the manufacture of the printing anti-counterfeiting pattern. The depth can be controlled by adjusting the thickness of the black lines (i.e., the ratio of the black to white area) in the mesh structure and adjusting the area size of the solid structure, and since the depth is too deep due to the density of the black lines in the mesh structure and cannot be distinguished from the depth of the solid structure, and the depth is too shallow due to the density of the black lines in the mesh structure and macroscopically generates a color difference, it is necessary to control the difference between the depths of the weave structure and the solid structure within an appropriate range.
In another embodiment of the present invention, the printed anti-counterfeit pattern may be manufactured by a direct engraving plate-making process, and in the step of making a plate based on the printed anti-counterfeit pattern, the plate-making is engraving plate-making, including: outputting three-dimensional data of the design pattern 40 containing the printing anti-counterfeiting pattern to plate-making equipment for executing laser engraving or numerical control micromachining according to rules; the plate making apparatus makes a master or a printing plate or a pad pasting by engraving in a laser engraving or a numerical control micro-machining manner based on the three-dimensional data of the design pattern 40. And printing on a machine after treatment to finish the manufacture of the printed anti-counterfeiting pattern.
Fig. 12a and 12b respectively show cross-sectional views of anti-counterfeiting patterns with different structures formed by the method for manufacturing printed anti-counterfeiting patterns, wherein the composition elements in the anti-counterfeiting patterns in fig. 12a have ideal rectangular cross-sections, and the composition elements in the anti-counterfeiting patterns in fig. 12b have trapezoidal cross-sections, that is, the edges of the cross-sections are slope-shaped, and in fact, the cross-sections are formed more in the corrosion process.
In addition, according to the principles of the present invention, there is also provided a security article having a substrate 30 with a printed security pattern as described above on the substrate 30. Specifically, an identifiable marker for preventing forgery may be added to the first pattern 10. The identifiable marker is visible or hidden data, image information, or ink. In addition, the inks used to print the printed security patterns of the present invention can be selected to exhibit different colors at different viewing angles.
The printed anti-counterfeiting pattern is manufactured in a mode different from the traditional mode, and patterns with special visual effects at different angles are formed by designing composition elements with special microscopic layouts. The printed anti-counterfeiting pattern can be applied to anti-counterfeiting of gravure, watermark, silk screen and the like of bank notes, so that the anti-counterfeiting capability of the bank notes is further improved, and the copying is more difficult due to the special structure and the manufacturing method of the anti-counterfeiting pattern.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
