Description
Technical Field
The invention belongs to the technical field of security anti-counterfeiting, and particularly relates to a banknote anti-counterfeiting technology and a banknote anti-counterfeiting method.
Background
At present, the known silk-screen printing anti-counterfeiting technology for securities, in particular bank notes, mostly adopts printing ink with anti-counterfeiting materials, such as pearlescent ink, OVI optically variable ink, OVMI magnetically oriented optically variable ink and the like, and belongs to the anti-counterfeiting technology of ink material anti-counterfeiting category. The combined anti-counterfeiting technology which takes the silk-screen printing pattern as the basic element, such as the combined anti-counterfeiting technology formed by the offset anti-counterfeiting ground pattern or the engraved gravure anti-counterfeiting pattern and the silk-screen printing pattern, has a certain enhancement on the anti-counterfeiting function based on the single anti-counterfeiting technology. Therefore, the combined anti-counterfeiting technology becomes a main technology of the banknote anti-counterfeiting technology and is an important content of the current banknote anti-counterfeiting technology research.
Heretofore, in the combined anti-counterfeiting technology including the screen printing technology, the anti-counterfeiting technology combined with the screen printing pattern mostly adopts a combination anti-counterfeiting pattern and technology formed by superposing a ground pattern printing pattern or an engraving intaglio printing pattern as a fixed pattern. The combined anti-counterfeiting pattern and technology have certain defects in anti-counterfeiting capability because the combined graphics and texts are invariable and become a common technology in the anti-counterfeiting field of paper money.
The embossing technology of codes (numbers) is also a common anti-counterfeit technology for banknote, but because the printed image is a variable image, even if the embossing technology and other anti-counterfeit technologies are commonly present on the surface of the banknote, the embossing technology is often presented independently in a certain specific area of the surface of the banknote, or the embossing technology and other printed images (such as anti-counterfeit shading or engraving gravure image) are presented in a mode of simple image-text superposition on the surface of the banknote. The embossing feature of the code (number) is independently presented or simply overlapped with other graphics and texts, and the position relationship between the patterns is difficult to be strictly and accurately limited because different printing devices are adopted for printing respectively, so that the anti-counterfeiting capability of the simple overlapped combination mode is also insufficient.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a novel combined anti-counterfeiting mark and an implementation method thereof, the method is based on a screen printing technology and a coding (number) embossing technology, patterns to be printed by the two printing technologies are overprinted in a combination mode which has strict requirements on the relative positions of images and texts, and a novel combined anti-counterfeiting method combining fixed images and texts with variable images and texts is formed.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
the combined anti-counterfeiting mark is formed by combining at least a pattern formed by screen printing and characters or patterns formed by embossing, a hollowed-out area is reserved on the screen printing pattern, and at least one part of the embossed characters or patterns is positioned in the hollowed-out area of the screen printing pattern and is in overprinting relation with the screen printing pattern. Wherein, the embossing is coding (number) embossing, and the same applies below.
As a preferable technical scheme, part or all of the outer contour of the embossed characters or patterns is completely or partially overlapped with the contour of the hollowed-out area of the screen printing patterns to form pattern splicing complementary relation.
As a preferable technical scheme, in the embossed characters or patterns, characters or patterns which have splicing complementary relation with the outline of the hollowed-out area of the screen printing pattern are invariable, and the rest embossed characters or patterns are invariable.
As a preferable technical scheme, a non-contact belt exists between part or all of the outer contour of the embossed characters or patterns and all or part of the outline of the hollowed-out area of the screen printing patterns.
The non-contact belt can be a non-contact belt with uniform width or a non-contact belt with variable width.
As a preferable technical scheme, in the embossed characters or patterns, characters or patterns related to the outline of the hollowed-out area of the screen printing pattern in a non-contact band manner are invariable, and the rest embossed characters or patterns are variable.
The screen printing pattern can be printed by adopting common screen printing ink, and can also be printed by adopting the screen printing ink with anti-counterfeiting material.
Also, the embossed characters or patterns can be printed by using common printing ink, and can also be printed by using printing ink with anti-counterfeiting materials.
The invention also provides a realization method of the combined anti-counterfeiting mark, which at least adopts two printing technologies of screen printing and embossing, and the design of the screen printing pattern is provided with a hollowed-out area, and part or all of the hollowed-out area and at least part of the outline of characters or patterns formed by the embossing form an overprinting relation.
The principle of the anti-counterfeiting technology of the invention is as follows: and (3) carrying out partial hollowed-out treatment on the screen printing pattern area to be printed, and carrying out strict overprinting on the outline formed by the hollowed-out area and the outline of the characters or patterns formed by the code (number) embossing. The strict overprinting ensures the position relation of the pattern outline formed by the two printing modes, and belongs to the printing anti-counterfeiting technology formed by the two printing modes. The two printing technologies in the anti-counterfeiting technology can adopt anti-counterfeiting ink, pattern design, printing technology and other materials, designs, technologies and other anti-counterfeiting technologies, and the combination of different anti-counterfeiting technologies can derive different anti-counterfeiting functions, so that the performance of the combined anti-counterfeiting technology is further enhanced, and the effect of increasing the counterfeiting difficulty is better played.
The combined anti-counterfeiting mark at least comprises characters or patterns formed by screen printing patterns and code (number) embossing, wherein the characters or patterns formed by the code (number) embossing are partially or completely nested and overprinted in a hollowed-out area of the screen printing patterns, and the combined anti-counterfeiting mark is formed by combining the characters or patterns in the form, so that a novel combined anti-counterfeiting technology combining fixed images and texts with variable images and texts is formed. The combined anti-counterfeiting technology effectively enhances the anti-counterfeiting performance, and meanwhile, the screen printing plate needing overprinting does not need to be frequently replaced.

Detailed Description
The invention is further illustrated in the following, in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. It is needless to say that the person skilled in the art realizes that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive in scope.
Example 1
As shown in fig. 1, the "BX49116981" in the figure is an alphanumeric code formed by embossing a code (number), and the first three digits (letters and numbers) "BX4" of the alphanumeric code are overprinted with the hollowed-out part of the screen printing pattern according to a strict positional relationship, which is a basic combination of the present invention.
Fig. 2 is a schematic view of the screen printed pattern and the hollowed-out area in fig. 1. Fig. 3 illustrates two sets of variable encodings (numbers) that may be adapted to the screen-printed pattern shown in fig. 2. According to the banknote coding method, a certain number of banknotes are usually printed, and the coding of high-order numbers or letters is only related to carry, so that in actual printing production, before the coding (number) carries to the high-order, the hollowed-out areas of the high-order numbers or letters corresponding to the screen printing patterns do not need to be changed, and the corresponding screen printing plates do not need to be replaced. In actual production printing corresponding to the present example, characters or patterns formed by the code (number) embossing will be carried by units, tens and hundreds … … to millions according to the carry rule, so that tens of millions of groups of variable code characters or patterns can be formed from BX40000000 to BX 49999999. In printing these codes (numbers), there is no need to replace the screen printing plate that needs overprinting.
Example 2
Referring to fig. 4, the present embodiment illustrates several overprinting relations between the hollowed-out parts of the screen printing pattern and the characters or patterns formed by the embossing of the code (number). The letter "B" and the outline of the hollowed-out area corresponding to the screen printing pattern form a splicing complementary relation, the letter "X" and the outline of the hollowed-out area corresponding to the screen printing pattern form a relation of a non-contact belt with uniform width, the number "4" and the outline of the hollowed-out area corresponding to the screen printing pattern form a relation of a non-contact belt with variable width, other numbers "9116981" are used as a part of codes, a strict overprinting relation exists between the numbers and the screen printing pattern, and the part of numbers are variable codes (numbers).
Example 3
Referring to fig. 5, this embodiment illustrates that the hollowed-out area of the screen printed pattern and the corresponding code (number) can be designed at any relevant position in the combined pattern, but it should be noted that features for facilitating visual recognition of the relative position are required between the two printed patterns, such as features of splice complementary, uniform non-contact tape or non-uniform non-contact tape formed by strict overprinting.
Example 4
Referring to fig. 6, this embodiment illustrates a process technology in which codes (numbers) are formed by adopting a wiring anti-counterfeiting process, and single strokes or lines of characters or patterns of the codes (numbers) are formed by splicing different colors. The code (number) printing technology has a certain anti-counterfeiting effect, and the technology further correlates characters or patterns in a group of codes by adopting different color splicing printing methods, and after overprinting with screen printing patterns, the anti-counterfeiting performance of the combined patterns is further enhanced.
Example 5
Referring to fig. 7, this embodiment illustrates a screen printing pattern using a combination of numbers (such as the number of screen printing denominations common to banknotes) and characters or patterns formed by embossing of codes (numbers).
The coding (number) lettering or pattern is strictly overprinted with the silk screen printing pattern, and accurate overprinting assurance is required for lettering equipment and silk screen printing equipment. However, in practice, when the two printing modes are not completed in one paper feeding process, overprinting accuracy cannot be guaranteed well. The practical situation has proved that if the screen printing and coding (number) embossing combined equipment is adopted, the printing in two modes of screen printing and coding (number) embossing can be completed under the condition that paper is positioned and fed on the equipment at one time, and the overprinting precision between patterns or characters formed by the two printing modes is better ensured.
Fig. 8 shows a schematic structural diagram of a screen printing and code (number) embossing combined printing apparatus. Referring to fig. 8, the combined printing apparatus includes a paper feeding mechanism 1, a screen printing mechanism 2, an ink drying mechanism 3, a letterpress printing mechanism 4 and a paper receiving mechanism 5, wherein after the paper feeding mechanism 1 feeds paper and positions the paper, the paper firstly enters the screen printing mechanism 2 to finish screen printing, and after the screen printing pattern is dried by the ink drying mechanism 3, the paper then enters the letterpress printing mechanism 4 to finish letterpress printing of the code (number). Because the twice printing is completed by adopting a paper positioning and paper feeding mode, the image-text overprinting precision error can be controlled within the range of less than 0.1mm, and the printing method has a good overprinting effect.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this invention, and are intended to be within the scope of this invention.
