Description

Security printed matter having a figure security pattern

The present invention relates to a security print, and to a security print in which a security pattern has a two-dimensional figure shape.

Recently, with the development of IT technology, as the resolution and reproducibility of computer-related devices such as scanners, printers, multifunction devices, and software are improved, crimes using easily copying banknotes, checks, various certificates, and security documents are increasing.

In order to solve this problem, a security print is printed on the security object or the case in which the security object is accommodated.

Although it is difficult to visually identify the detailed print contents of security prints, forgery is prevented by revealing a unique security pattern when copying. Alternatively, the security print is difficult to identify with the naked eye, but forgery is determined by analyzing a device having a high resolution and an image captured by the device.

In the security print, it is preferable that the hiding power of the security pattern is strengthened so that it is difficult to identify the security pattern with the naked eye. And, it is preferable that the security pattern is copied well when copying the security print.

Since the present invention can have various changes and can have various embodiments, specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that all modifications, equivalents and substitutes included in the spirit and scope of the present invention are included.

In describing each figure, like reference numerals have been used for like elements. In describing the present invention, if it is determined that a detailed description of a related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

Terms such as first, second, etc. may be used to describe various elements, but the elements should not be limited by the terms. The above terms are used only for the purpose of distinguishing one component from another.

For example, without departing from the scope of the present invention, a first component may be referred to as a second component, and similarly, a second component may also be referred to as a first component.

When the security pattern is expressed as a one-dimensional line, the degree to which the security pattern is clearly copied (radiation power) may be different depending on the copying direction. In addition, when the security pattern is formed of dots, the size of the dots is inevitably large so that the security pattern can be copied well during copying. Therefore, if the security pattern is formed as dots while guaranteeing the copying power of the security pattern, the hiding power of the security pattern is lowered.

The present invention improves the hiding power by using the security pattern as a figure division method, and at the same time, the security pattern can be easily displayed at the time of copying regardless of the copying direction. Here, the term “surface” means that the area intended to be copied in the security pattern is copied by the copier when copying.

The security pattern may be printed on a print medium such as paper. In this case, the background pattern may be printed by overlapping the security pattern. The background pattern may be a pattern or a picture that conceals the security pattern while being identified with the naked eye.

In the present invention, the security pattern may have a regular polygonal shape. That is, in the present invention, the security pattern may be any one of an equilateral triangle, a square, a regular pentagon, ..., and an n-gonal. And, in the present invention, the security pattern may have a circular shape. The security pattern as a whole may be visually identifiable. However, it may be very difficult or impossible to visually distinguish the area that is radiated by the hiding power from the area that is not radiated.

In the present invention, by forming a security pattern in the form of a regular polygon or a circle, the same or similar radiant power can be obtained in the entire direction in which the radiation proceeds. Depending on the copying direction, the radiation power of a portion of the copied area of the security pattern may be low, but due to the characteristics of a long polygon and a circle, the outline of the copied area of the security pattern may appear very clearly when copying.

Referring to FIG. 1 , the security pattern may be divided into an area 1 to be copied and an area 2 not to be copied. 1 illustrates a case in which a figure forming a security pattern is a square.

In the region 1 to be copied, the radiation line 120 may form a half of the line 100 constituting the figure. The thickness of the radiation line 120 may be determined according to the resolution of the copying machine. The radiation line 120 must be copied by a copy machine, and must be concealed by combination with the non-radiation line 110 . In this regard, the thickness of the radiation line 120 is preferably 10 to 25 μm. If the thickness of the radiation line 120 is less than 10 μm, radiation may be difficult and there may be a situation in which radiation is hardly performed in some directions. If the radiation line 120 thickness is greater than 25 μm, the hiding power may be insufficient. In addition, when the thickness of the radiation line 120 is greater than 25 μm, it can be easily distinguished from the non-radiation line 110 with the naked eye.

In the non-copy area 2 , the non-radiation line 110 may form a half of the line 100 forming the figure. The non-radiation line 110 may have a thickness of less than 10 μm.

A figure may be formed by connecting the radiation line 120 and the non-radiation line 110 to each other. Here, the figure may be a regular n-gon (n is an integer greater than or equal to 3) or a circle. 1 , the figure may be a square.

The area of the figure formed by the radiation line 120 and the non-radiation line 110 may be equally divided into a copied area and a non-copy area.

The security pattern may be formed of a plurality of radiation lines 120 and a plurality of non-radiation lines 110 . The widths of the plurality of radiation lines 120 may be the same. The widths of the plurality of non-radiation lines 110 may be the same. The plurality of radiation lines 120 may be spaced apart from each other at the same interval. The non-radiation lines 110 may be spaced apart at equal intervals. The plurality of radiation lines 120 and the plurality of non-radiation lines 110 may be the same number. Each of the plurality of radiation lines 120 may be connected to any one of the plurality of non-radiation lines 110 corresponding thereto to form a regular n-gonal shape or a circle. The plurality of figures formed by the plurality of radiation lines 120 and the plurality of non-radiation lines 110 may have different sizes, and lines forming the figure may have the same center and may be spaced apart from each other by the same interval.

A dummy line 200 may be inserted between adjacent non-radiation lines 110 . The width of the dummy line 200 may be the same as the width of the non-radiation line 110 .

The dummy line 200 may be located at the center of the neighboring non-radiation line 110 .

The dummy line 200 may be disposed parallel to the non-radiation line 110 .

The dummy line 200 may be formed only on the non-copy area 2 .

The dummy line 200 may be located in a space between the neighboring non-radiation lines 110 and may be a line connecting all points located at the center between the neighboring non-radiation lines 110 .

Accordingly, the dummy line 200 may have a shape corresponding to a regular n-gonal or half of a circle.

The density of the radiation line 120 in the unit cell C in the area to be copied may be the same as the density of the non-radiation line 110 and the dummy line 200 in the unit cell C in the area not to be copied. .

Accordingly, it may be difficult to visually identify the radiation line 120 , the non-radiation line 110 , and the dummy line 200 , so that the hiding power of the security pattern may be improved.

In addition, since the radiation line 120 and the non-radiation line 110 are connected to each other to naturally form a figure, the hiding power of the security pattern may be further improved.

If the security pattern of FIG. 1 is copied, it may be copied as shown in FIG. 5 . The area 1 that is not copied in the security pattern may be recognized as a blank in the copier.

Referring to FIG. 2 , the figure forming the security pattern may be a circle.

In the area 1 to be copied, the radiation line 120a may form a half of the line 100 forming the figure. The thickness of the radiation line 120a may be determined according to the resolution of the copying machine. The radiation line 120a must be copied by a copy machine, and must be concealed in combination with the non-radiation line 110a. In this regard, the thickness of the radiation line 120a is preferably 10 to 25 μm. If the thickness of the radiation line 120a is less than 10 μm, radiation may be difficult and there may be a situation in which radiation is hardly performed in some directions. When the thickness of the radiation line 120a is greater than 25 μm, the hiding power may be insufficient. In addition, if the thickness of the radiation line 120a exceeds 25 μm, it can be easily distinguished from the non-radiation line 110a with the naked eye.

In the non-copy area 2 , the non-radiation line 110a may form a half of the line 100a forming the figure. The non-radiation line 110a may have a thickness of less than 10 μm.

A figure may be formed by connecting the radiation line 120a and the non-radiation line 110a to each other. Here, the figure may be a regular n-gon (n is an integer greater than or equal to 3) or a circle.

The area of the figure formed by the radiation line 120a and the non-radiation line 110a may be equally divided into a copied area and a non-copy area.

The security pattern may be formed of a plurality of radiation lines 120a and a plurality of non-radiation lines 110a. The plurality of radiation lines 120a may be spaced apart from each other at the same interval. The non-radiation lines 110a may be spaced apart from each other at equal intervals. The number of the plurality of radiation lines 120a and the plurality of non-radiation lines 110a may be the same. Each of the plurality of radiation lines 120a may be connected to any one of the plurality of non-radiation lines 110a corresponding thereto to form a regular n-gonal shape or a circle. In FIG. 2 , the figure may be a circle.

A dummy line 200a may be inserted between adjacent non-radiation lines 110a.

The dummy line 200a may be located at the center of the neighboring non-radiation line 110a.

The dummy line 200a may be disposed parallel to the non-radiation line 110a.

The dummy line 200a may be formed only on the non-copy area 2 .

The dummy line 200a may be located in a space between the neighboring non-radiation lines 110a and may be a line connecting all the points located at the center between the neighboring non-radiation lines 110a.

Accordingly, the dummy line 200a may have a shape corresponding to a regular n-gonal or half of a circle.

The density of the radiation line 120a in the unit cell C in the area to be copied may be the same as the density of the non-radiation line 110a and the dummy line 200a in the unit cell C in the area not to be copied. .

Accordingly, it may be difficult to visually identify the radiation line 120a, the non-radiation line 110a, and the dummy line 200a, so that the hiding power of the security pattern may be improved.

In addition, since the radiation line 120a and the non-radiation line 110a are connected to each other to naturally form a figure, the hiding power of the security pattern may be further improved.

Referring to FIG. 3 , the radiation line 120b may include a first radiation line 121b, a gap line 123b, and a second radiation line 122b. The first radiation line 121b, the gap line 123b, and the second radiation line 122b may be sequentially disposed. In FIG. 3 , the total width of the first radiation line 121b , the gap line 123b , and the second radiation line 122b may be 25 μm to 35 μm. The width of the gap line 123b may be less than 10 μm. Accordingly, the copier may not recognize the gap line 130b as a blank space. That is, due to the narrow width of the gap line 123b, the copier may determine the gap line 130b as a printed area. The minimum thickness of the first radiation line 121b and the second radiation line 122b for recognizing that the copying machine is a printing area is sufficient. Accordingly, each of the first radiation line 121b and the second radiation line 122b may have a thickness of 10 μm or more. Each of the first radiation line 121b and the second radiation line 122b may have a thickness of less than 20 μm. By adding the gap line in this way, during copying, the copied area 1 can be copied with a thickness corresponding to the entire width of the first radiation line 121b, the gap line 123b, and the second radiation line 122b. have. Accordingly, the radiant power of the region to be copied during copying may be increased. In addition, the radiation line 120b is divided into the first radiation line 121b and the second radiation line 122b with the gap line 123b interposed therebetween, and the first radiation line 121b and the second radiation line 122b are formed. By narrowing each width compared to the single radiation line 120 of FIG. 1 , the hiding power of the radiation line 120b may be further improved.

The non-radiation line 110b may be disposed to continue to the gap line 123b.

Referring to FIG. 4 , the radiation line 120c may include a first radiation line 121c, a gap line 123c, and a second radiation line 122c. The first radiation line 121c, the gap line 123c, and the second radiation line 122c may be sequentially disposed. In FIG. 4 , the total width of the first radiation line 121c , the gap line 123c , and the second radiation line 122c may be 25 μm to 35 μm. The width of the gap line 123c may be less than 10 μm. Accordingly, the copier may not recognize the gap line 130c as a blank space. That is, the copier may recognize the gap line 130c as a printed area. It is sufficient that the first radiation line 121c and the second radiation line 122c have a minimum thickness for recognizing that the copying machine is a printing area. Accordingly, each of the first radiation line 121c and the second radiation line 122c may have a thickness of 10 μm or more. Each of the first radiation line 121c and the second radiation line 122c may have a thickness of less than 20 μm. By adding the gap line in this way, during copying, the area 1 to be copied can be copied with a thickness corresponding to the entire width of the first radiation line 121c, the gap line 123c, and the second radiation line 122c. have. Accordingly, the radiant power of the region to be copied during copying may be increased. A figure formed while the first radiation line 121b and the second radiation line 122b formed narrower than the single radiation line 120 of FIG. 1 are continuous with the non-radiation line 110b is the first radiation line 121b Since the continuity of the thickness between the radiation lines 111b and the thicknesses of the second radiation line 122b and the non-radiation line 110b is high, the hiding power of the radiation line 120b may be further improved. In addition, the radiation line 120c is divided into the first radiation line 121c and the second radiation line 122c with the gap line 123c interposed therebetween, and the first radiation line 121c and the second radiation line 122c are formed. By narrowing each width compared to the single radiation line 120 of FIG. 1 , the hiding power of the radiation line 120c may be further improved. In addition, the figure formed by connecting the first radiation line 121c narrower than the single radiation line 120 of FIG. Since the continuity of the thickness is high, the hiding power of the radiation line 120c may be further improved. Unlike FIG. 4 , the non-radiation line 110c may be formed to be connected to the second radiation line 122c instead of the first radiation line 121c. At this time, the figure formed by connecting the second radiation line 122c narrower than the single radiation line 120 of FIG. Since the continuity of the thickness is high, the hiding power of the radiation line 120c may be further improved.
