In order to solve such problems, various forgery-proof prevention halftone dots have been developed. Conventionally, a method of preventing forgery and falsification by using ultraviolet ink, infrared ink, hologram, or the like has been attempted. However, It is possible to confirm the authenticity, but it does not matter to recognize the contents of the original. In addition, it is inevitable to increase the production cost due to the additional application of hologram or ink, etc. due to raw materials, labor costs and additional processes.

In order to solve the above problems, the copy-forgery-inhibited printing material developed has various shapes such as lines and halftone dots, large halftone dots and small halftone dots, angle conversion between dotted and dotted lines, and elongated curves in which dotted lines and lines or angles are converted. To prevent counterfeiting.

Such patent documents relating to such copy-forgery-inhibited printing articles include Korean Patent No. 1164003 and No. 0369111. However, the conventional copy-forgery-inhibited prints have a simple structure and a pattern, which makes it easy to grasp the origin of the latent image.

Hereinafter, with reference to the accompanying drawings 1 to 18, a description will be made of a method of manufacturing a latent image print for anti-falsification and a latent image printed matter according to a preferred embodiment of the present invention. In the following description, for the sake of clarity of the present invention, a description of what has been conventionally known will be omitted or simplified.

1 and 2 are views for explaining a latent image printed matter according to an embodiment of the present invention. The latent image printed matter 1000 includes a background region 10 formed by a plurality of background dashed line lines 210 on the printing paper 200, a plurality of latent dotted line lines 220 and a plurality of concave and dashed dotted lines 230, And an area section (30). At this time, the uneven dashed line 230 is generated by the pressing of the steel plate 100, and a plurality of unevenness are arranged.

A plurality of dotted lines 210 and 220 of the background area 10 and the latent image area 20 form a circle 300. The circle formation can be described with reference to FIGS. 3 is a view for explaining the formation of a circle according to an embodiment of the present invention. 4 is an enlarged view of A1 for explaining the dotted line in Fig. FIGS. 5 and 6 are views for explaining the dotted line spacing when the circle is formed in FIG. 7 is a view for explaining formation of a latent image area according to an embodiment of the present invention.

Here, FIGS. 3 to 7 illustrate the principle of the uniaxial direction as an example, and the principle of the other axial direction may be formed in the same manner.

The background region section 10 includes a plurality of background dashed lines arranged in parallel with each of at least two axial directions intersecting at the center. 4, the background dashed line is formed by a plurality of unit point line portions U, and the unit point line portion U includes a dot line portion a forming a dotted line and a blank portion b forming a blank do. At this time, the end points (S1, S2, S3) of the dotted line portion (a) for determining the length of the dotted line portion (a) are randomly formed. That is, the length of the dotted line portion a is randomly formed in the formation of the background dashed line, so that it is not easy to grasp the constitution principle of the original dotted line.

If the density of the dotted line portion a is 80 or more, it is difficult to grasp the generation process of the latent image. When the density of the dotted line portion a is less than 60, The effect of latent image is deteriorated due to easy confirmation. Accordingly, it is preferable that the unit point line portion U is formed such that the density of the dotted line portion a and the blank portion b is 60 to 80: 40 to 20.

The background dashed line 210 is formed by a plurality of unit point line portions U1, U2, U3, ... arranged along the corresponding axial direction, and the background region portion 10 includes a plurality of And is formed by the background dashed line 210.

Referring to FIG. 5, when two axes are used, a background dashed line 210 formed along a first axis which is 45 degrees with respect to the longitudinal direction of the printing roller R, A background region A composed of lines and a background region B composed of background dashed lines formed along a second axis of 135 degrees with respect to the longitudinal direction of the printing roller R can be used in the generation of the circle. This is because when the original plan C composed of two axes is printed by the operation of the printing roller R in the rolling direction X, the thickness error range between the dashed lines formed along the two axes Can be solved.

6, the background dashed line can be formed so as to be 0 degree, 60 degrees, and 120 degrees based on the rotation direction of the printing roller .

In this case, referring to FIG. 5, the spacing distance P between the background dashed lines of the respective axes is 1: 1 in the case of two axes, that is, the background dashed lines are spaced apart at equal intervals. 6, the distances P1, P2, and P3 between the background dashed lines of the first axis, the second axis, and the third axis are set to be 1: 1: 1.2 to 1.8 in the case of three axes, .

The latent image area 20 specifies an area corresponding to one of characters, graphics, and images for realizing different latent images on the background area part 10 in each axial direction, and a plurality of latent image dot lines Are arranged so as to be parallel to and spaced from the neighboring background dotted lines.

7, an area T corresponding to "o" for realizing a latent image is designated on the background area part 10 as shown in Fig. 7 (a). At this time, the background dashed line included in the area becomes the latent dotted line. The plurality of latent dotted line lines included in the area T specified as shown in FIG. 7 (b) are arranged in parallel to and spaced apart from the neighboring background dotted lines to form the latent image area part 20. [

Although only one axis is described in Fig. 7, the formation of the latent image portion of another axis can also be performed in the same manner. Since the latent image dotted line of the latent image area 20 is formed using the background dotted line of the background area 10, the spacing distance between the latent image dotted lines is 1: 1 in the case of two axes and 1 : 1: 1, 2 to 1.8. In addition, the slope of each axis is also applied to the slope of the corresponding background area section 10.

The original 300 is composed of a background area 10 and a latent image area 20, and a circle formed by each axis is synthesized to form a circle of printed matter. At this time, the plurality of background dotted line 210 and the latent dotted line 220 may have at least one of characters, figures, and images (photographs, pictures, etc.) .

The latent image printed matter 1000 according to the present invention can be easily corrected by dotted line correction on the border area between the background area 10 and the latent image area 20, And then pressing the steel plate 100.

Description of dotted line correction on the border area between the background area 10 and the latent image area 20 will be explained with reference to Figs. 8 to 10. Fig. The correction for the portion A2 in FIG. 3 will be described as an example, but the dotted line correction on the boundary region between the background region 10 and the latent image region 20 can be performed in the same manner as in FIGS. 8 to 10 .

 FIG. 8 is a view for explaining the primary correction for the latent image boundary area in FIG. 3; FIG. FIG. 9 is a diagram for explaining secondary correction for the primary-corrected latent-image boundary area in FIG. FIG. 10 is a diagram for explaining the third-order correction for the second-corrected latent-image boundary area in FIG.

8, a dotted line portion having a density of 50% or more of the dotted line portion of the background dashed line and the latent dotted line located in the boundary region between the background region portion 10 and the latent image region portion 20 is referred to as the reference dotted line portion 1 Differential correction. Here, the dotted line portion is formed at a density of 60 to 80 when the unit dotted line U is taken as 100 as described in Fig. Here, the reference point line portion is a dotted line portion formed at a density of 60 to 80, and has a rectangular shape.

On the other hand, the dotted line which is less than 50% of the boundary area maintains the density and corrects the shape only. At this time, the shape of the dotted line portion may be the same as the shape of the reference dotted line portion. At this time, the rectangular shape is one embodiment and may be changed to another shape.

8A, a dotted line portion having a density of 50% or more of the reference dotted line portion among the dotted line portions in the boundary region is extracted as a correction target (L1: red), and the density and shape of the extracted correction target dotted line are set as reference points Correct as with the front part. Fig. 8 (b) shows that the L1 in Fig. 8 (a) has been corrected to be L1 in Fig. 8 (b) as a result of the primary correction.

Referring to Fig. 9, the dashed line in the dashed line portion of the first corrected boundary region in Fig. 8 (b) is cut by 30% or less of the density of the dashed line portion with respect to the reference point dashed portion.

That is, in FIG. 9 (a), the dotted line portion having a density of 30% or less of the reference dotted line portion is extracted as the correction object (L2: red), and the extracted correction object dotted line portion is deleted. On the other hand, the dotted line which is more than 30% of the boundary area maintains the density and corrects the shape only. At this time, the shape of the dotted line portion may be the same as the shape of the reference dotted line portion. 9 (b) is a result of secondary correction, and L2 in Fig. 9 (a) is deleted as shown in Fig. 9 (b).

10, when the margin 40 is formed in the continuous unit dotted line U by the secondary correction, that is, the deletion of the dotted line, the arrangement direction of the background dotted line or the latent dotted line adjacent to the margin 40 To generate additional dotted lines. At this time, in order to confirm the margin 40 of the continuous unit dotted line U, for example, a window (filter) of twice or more times the unit dotted line U is formed, and the dotted line portion of the boundary region and the pre- The margin 40 can be determined by applying a window to the dotted line portion in FIG. At this time, the window is moved by the unit point line U and sequentially applied, and the margin 40 can be determined when the sum of the densities of the dotted lines in the window is out of the preset range. At this time, the initial setting range can be set according to the density of the unit point line U corresponding to the applied window size.

Further, when it is judged as the margin 40, an additional dotted line portion is generated along the arrangement direction of the background dashed line or the latent dotted line adjacent to the margin 40, and the density of the generated additional dotted line portion is determined according to the density of the peripheral unit dotted line . 10 is a result of third-order correction, and the dotted line L3 is added to the margin 40 in FIG. 9 (b) as shown in FIG.

Comparing the boundary area correction before (A2) of FIG. 4 with the boundary area after correction of FIG. 10, the boundary area is not striking and smoothly corrected, so that it is not easy to grasp the configuration of the original image.

The image to be applied to the latent image printed matter 1000 can be finely implemented by correcting the thickness of the dotted line of the original image 300 to which the boundary region correction of the background area unit 10 and the latent image area unit 20 is applied. The description of the correction of the thickness of the dotted line of the circle 300 can be explained with reference to Figs. 11 is a color-separated view of an image to be applied to a printed matter as G, Y, R, and B. FIG. Fig. 12 is a diagram for explaining correction of the dotted line thickness of the circle diagram using Fig.

Referring to FIG. 11, when the latent-image printed matter 1000 of the present invention is to be implemented as a parrot image, a parrot image to be applied to the original image 300 is color-separated to generate an image of each color (G, Y, R, B) .

Correction of the thickness of the dot-line part is performed by matching the position of the circle-by-color of the color-corrected image of each color and the corrected color of the boundary area and correcting the thickness of the dot-line part of the circle by color according to the image contrast of each color of the matched position do. In this case, a lookup table in which the thicknesses of the dotted line portions corresponding to the darkness 0 to 100 are leveled and matched can be used.

Referring to Fig. 12, the dotted line section U4 is divided by the preset gap G, and the thickness is corrected in units of the preset gap G. At this time, the maximum thickness Max is less than 3/5 times the spacing distance P between the background dotted lines, and the minimum thickness Min is corrected to be 40 m.

13 is a diagram for explaining a final plan according to an embodiment of the present invention. 13 (a), 13 (b), and 13 (c) for each color (each axis direction) to which boundary region correction and dot line thickness correction are applied, .

13 (d), the boundary between the background area 10 and the latent image area 20 is smoothly represented by the boundary area correction, and the latent image area is not seen prominently. In addition, through the correction of the thickness of the dot-dot portion, not only simple characters and graphics but also images such as photographs can be used for latent-image printing.

Fig. 14 is a view for explaining the intaglio plate and the concavo-convex line to be applied to the final plan of Fig. 13. Fig. 1 and 2, when the final original 300 having the boundary area correction and the dot line thickness correction is formed, the latent image printed matter 1000 to which the indented dashed line 230 is applied by pressing the indented plate 100, .

Referring to Fig. 14 (a), the steel plate 100 has a concavo-convex line 110 arranged in parallel with at least two axial directions intersecting the center, and a concave portion 120 formed by the concavo-convex line. Therefore, when the plated board 100 is pressed in the final plan view 300, a plurality of uneven dashed line lines 230 overlapping the plurality of background dotted line lines 210 and the plurality of latent dotted line lines 220 are formed.

Fig. 14 (b) shows one dotted line of the uneven dashed line 230 formed by the steel plate 100. Fig. The upper surface 60 has a plurality of background dotted line lines 210 and a plurality of latent dotted line lines 220, The image is implemented.

15 is a view for explaining a latent image of a latent image printed matter according to an embodiment of the present invention. 15, a latent image printed matter 1000 formed of a latent image 300 formed of a background area 10 and a latent image area 20 formed in a three-axis direction and a concave-convex area 30 is described as an example . The latent image printed matter 1000 is formed in the axial direction of 0 degree, 60 degree and 120 degree with respect to the longitudinal direction of the printing roller when forming the background dashed line and the latent dotted line. Further, by the pressing of the steel plate 100, a plurality of lines of dashed and dotted lines overlapping between the background dotted line and the latent dotted line are formed.

The latent image formed on the latent image area is visually confirmed when the latent image printed matter 1000 is tilted in a specific axial direction of 0 degrees, 60 degrees, and 120 degrees.

15 (a) is a finally formed latent image printed matter 1000, and when the latent image printed matter 1000 is tilted in the first direction (a to a '), an "angler" formed in the latent image area portion is visually confirmed. On the other hand, even when the latent-image printed matter 1000 is tilted in the reverse direction (a 'to a) in the first direction, an "angled" character is visually confirmed.

In addition, when the latent image printed matter 1000 is tilted in the second direction (c 'to c'), a "no" formed on the latent image area is visually confirmed. On the other hand, even if the latent image printed matter 1000 is tilted in the reverse direction (c 'to c) in the second direction, "no" is visually confirmed.

In addition, when the latent image printed matter 1000 is tilted in the third direction (b '), the "new" formed on the latent image area is visually confirmed. On the other hand, even if the latent image printed matter 1000 is tilted in the reverse direction (b 'to b) in the third direction, the "new"

As a result, the latent image printed matter 1000 according to an embodiment of the present invention can visually check at least two latent image images to check whether or not the image is forged. The latent image printed matter 1000 forms a latent image by constituting the final original 300 to which the dotted line correction on the border area between the background area 10 and the latent image area 20 and the dotted line thickness correction on the original are applied It is not easy to grasp the constitutional principle of the circle. Thus, it is possible to prevent forgery and falsification of the latent image printed matter 1000.

16 is a flowchart for explaining a method of manufacturing a latent image printed matter according to an embodiment of the present invention. Referring to FIG. 16, a color diagram for each color including the background area 10 and the latent image area 20 is formed (S100). This can be explained with reference to FIG. FIG. 17 shows a method of forming a circle of a specific color composed of a background dashed line and a latent dotted line formed in a unidirectional direction, and a circle of another color formed in another axis direction can be formed by the same method.

A plurality of background dashed line lines formed by a plurality of unit dashed line portions U arranged in the axial direction are formed (S111), and latent images (one of characters, figures and images) are formed in the axial direction on the plurality of background dotted line lines (S112). Next, the background dotted line lines included in the formed latent image are shifted to be shifted in parallel with the background dashed line lines of the background area section 10 to form the latent image area section 20. [ At this time, the background dashed line included in the latent image area 20, that is, the shifted background dotted lines, becomes a latent dotted line that realizes the latent image. At this time, the density of the unit dotted line portion U constituting the background dashed line and the spacing distance P between the dotted line portions can be adjusted, and the description thereof has been described in detail with reference to FIG. 3 to FIG.

Next, when the original color of each color is formed, the boundary area correction of the background area 10 and the latent image area 20 is performed (S110). At this time, the boundary region correction is performed for each color of each color, and a description thereof can be described with reference to FIG.

18, it is determined whether the density of the dotted line in the background dotted line and the latent dotted dotted line located in the border area between the background area and the latent image area is 50% or more of the reference dotted line (S111) Y) The correction target dotted line is corrected to the reference dotted line (S113). At this time, the reference dotted line portion becomes the unit dotted line portion U.

On the other hand, the dotted line portion S111: Y having less than 50% of the boundary region maintains the density and corrects only the shape (S113). At this time, the shape of the dotted line portion may be the same as the shape of the reference dotted line portion. At this time, the rectangular shape is one embodiment and may be changed to another shape.

Next, it is determined whether the density of the dotted line in the background dotted line and the dotted line in the boundary area is 30% or less of the reference dotted line (S114). If the density is 30% or less (S114: Y) ). On the other hand, the dotted line portion S114 (N) in which the density of the dotted line portion of the boundary region exceeds 30% of the reference dotted line portion maintains the density and corrects only the shape (S113). At this time, the shape of the dotted line portion is corrected to the same shape as the shape of the reference dotted line portion.

Next, when a margin is formed in the continuous unit point line portion U by deleting the correction target dotted line portion (Y in S116), an additional dotted line portion is generated along the arrangement direction of the background dotted line or the latent dotted line adjacent to the margin (S117).

Next, when the correction of the boundary area is completed, the image to be applied to the original image 300 is color-separated by color (S130), and the thickness of the dot line portions constituting the original color plane is corrected using S140 ).

In this case, the position of the color plane of each color is matched with the position of the circle plane of each color, and the thickness of the point plane of each circle is corrected according to the image contrast of each color of the matched position. At this time, the thickness of the dotted line can be corrected in units of preset intervals. Further, the maximum thickness Max of the dotted line to be corrected is less than 3/5 times the spacing distance P between the background dotted lines, and the minimum thickness Min is set to 40 占 퐉.

The final latent image 300 is formed by pressing the platen 100 to form a concavo-convex dotted line (S160). The final latent image 300 (1000).

At this time, the steel plate 100 has concave and convex lines arranged in parallel with at least two axial directions intersecting at the center, and concave portions formed by the concave and convex lines, and formed in the same direction as the axial direction when the background dotted line is formed. Accordingly, since the concavo-convex dotted line is formed between the plurality of background dotted lines and the latent dotted line, the latent image can be visually confirmed when the latent image printed matter 1000 is tilted at a specific slope.

It will be apparent to those skilled in the relevant art that various modifications, additions and substitutions are possible, without departing from the spirit and scope of the invention as defined by the appended claims. The appended claims are to be considered as falling within the scope of the following claims.
