Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a passport booklet, an entry visa, securities, banknotes, bank cards, cash cards,
Prevention of forgery of ID, license, entry certificate or stamps,
The present invention relates to a valuable printed matter that requires tampering prevention and copy prevention, and a manufacturing method thereof.

[0002]

2. Description of the Related Art In recent years, valuable printed matter requiring anti-counterfeiting, tampering prevention, and copy prevention as described above can be easily identified in the general distribution process due to the progress of reproduction technology such as color copying and scanning. The measures that can be taken are becoming important.

As a means for preventing counterfeiting and tampering of valuable printed matter such as securities and stamps, there are plows and the like, but it is an authenticity judgment element by human vision and cannot be a judgment element by machine processing. The current situation.

In addition, regarding valuable printed matter which requires authenticity discrimination and is subjected to machine identification processing, conventionally, for example, it is printed with fluorescent ink, magnetic ink, or the like, or fluorescent fiber or magnetic fiber is included in the paper, Although these are optically and magnetically judged as authenticity, these are not perfect safety measures for forgery prevention, tampering prevention, and copy prevention. Since special fibers are required, it is not suitable as a means for easily determining the authenticity of ordinary printed matter that does not use special ink.

Further, the peeling strength of the facing paper of the passport booklet in which personal information is written and protected by the laminating film is weakened, and when the laminating film is tried to be peeled off, the facing paper remains on the laminating film side, and forgery or Tamper-proof measures are used. However, even if the personal printing information on the return paper is broken by peeling off like this, personal information can be easily created by using a high-performance personal computer and high-performance image processing software, which have been remarkably popularized recently. It can be easily forged or tampered with by laminating a laminating film.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. The present invention is a valuable printed matter having anti-counterfeiting and tampering prevention effects and can be applied to various printed matters. Hereinafter, examples in which the valuable printed matter of the present invention is applied to a passport booklet and a bill will be described respectively.

(Embodiment 1) FIGS. 1 to 3 are views for explaining Embodiment 1 in which a valuable printed material according to the present invention is applied to a passport booklet. In FIG. 1 and FIG. 2, a kerf 2 (mounting sheet), which is a cover of the passport booklet 1, and a facing sheet 3 (base material) on which personal information is written are adhered to each other with an adhesive 4.

Offset paper 3 is provided with printing 5, 5'of lines and personal information by black ink on the facing paper 3. This ink contains no fluorescent substance. Then, the facing sheet 3 is thermocompression-bonded by the laminating film 6 and laminated.

Regarding the passport booklet 1 having such a structure, the carbon dioxide laser marker 7 is used to emit the laser beam 8 when the passport booklet 1 is issued.
Irradiate a part of the laminate film 6, for example, a part corresponding to the print 5 of the print surface of the personal information of the facing paper 3,
The groove 9 is etched.

The depth of the groove 9 is determined by adjusting the power of the laser beam 8, but if the power is too strong,
It is not desirable because it penetrates the laminate film 6 and irradiates the facing paper 3 too much, and the printing surface of the facing paper 3 is destroyed by the laser beam. When the groove 9 is etched in the laminate film 6 by the laser beam 8, the power of the laser beam 8 causes the ink on the printing surface of the facing paper 3 to be thermally affected and deteriorated. Thus, the depth of the groove 9 is preferably such that the printing surface of the facing sheet 3 is not destroyed and the ink is thermally affected. In this way, the passport booklet 1 according to the present invention is completed.

In the passport booklet 1 thus constructed,
As shown in FIG. 3, the surface of the laminate film 6 is irradiated with ultraviolet rays 10. Then, the ink in the print 5 portion of the facing paper 3 which is affected by heat is colored red by light in the red region, which is a wavelength region longer than the ultraviolet wavelength region. Even on the printed surface of the facing sheet 3, such a red color is not seen in the print 5 ′ in the region where the groove is not etched in the laminate film.

In Example 1, specifically, personal information is printed on the facing paper 3 after lamination with black ink, and the wavelength λ of 10. Scanning speed of 38 using a carbon dioxide laser marker of 4 μm and low output of about 12 W
Etching is performed at 5 mm / sec and a laser power output of 40%. Here, the black ink was prepared under the conditions of 10% carbon black, which is a coloring pigment, 8% dioxane violet, and 82% varnish for wet offset. The key to making it appear red is the incorporation of dioxane violet. The color observed in the visible light region can be changed by blending with other coloring pigments.

When the passport booklet thus constructed is observed under visible light, the laser beam-irradiated print 5 and the non-irradiated print 5'also appear black. However, when the surface of the laminate film 6 is irradiated with ultraviolet rays, the print 5 ′ looks black, but the print 5 part appears red.

Although the theoretical basis for different colors to be printed by laser beam irradiation has not been fully clarified, the molecular structure of dioxane violet in the pigment of the ink is changed, which is one of the causes. It is considered that when it is irradiated with ultraviolet rays, it develops red. In addition to this, it is considered that the vividness of the color development is further improved due to the combination of the PET film material used as the laminate film and dioxane violet.

According to the experiment, when the laser power output is 30% or less, the degree of color development is small. It is considered that the reason for this is that the laser beam 8 does not exert a sufficient thermal influence because the etching depth of the laminate film 6 is small.

The passport booklet 1 according to the first embodiment is printed with the same black ink, and even if the printed surface has no visible difference under visible light, the print 5 in the area where the laminate film is etched and other than that. In the area 5'of the print, it looks different when irradiated with ultraviolet light.

Therefore, after peeling off the laminate film 6 and the return paper 3 of the authentic passport booklet 1, the personal information and the like are forged and printed on the return paper 3 and attached to the kerf 2, and the laminate film 6 is laminated. Even if the passport booklet is forged or falsified, if it is irradiated with ultraviolet rays,
Since it does not appear red and appears black, it is easy to check forgery or falsification.

In this case, even if the laminated film is
Even if the groove is forged by performing precision machining with a needle or an embossing roller, the personal information on the facing sheet is not affected by heat by the laser beam, so that red coloring does not occur.

Further, even if the groove is forged by etching with a laser beam, it is extremely difficult to form a groove having the same depth as the groove due to the power of the laser beam, and it is extremely difficult to heat the ink. However, the hue of the coloring is different.

Furthermore, only a part of the printed characters (eg.
By etching the groove on the part of the laminating film on the lower side or the right side only) and giving a heat effect, when this character is seen with visible light, even if the whole character looks like the same color, it is irradiated with ultraviolet rays. It is also possible to make only a part of them develop different colors.

Even if the laminated film formed in this way is peeled off and counterfeit paper 3 is forged and printed, and the laminated film is affixed and the laminated film is intentionally etched by a new laser beam, the genuine passport booklet can be obtained. It is extremely difficult to apply heat to the same part as the part that gives heat to the character, and when irradiated with ultraviolet rays with visible light, different colors of the same character are used in a genuine passport booklet and a forged or tampered booklet. Since the color-developed part is slightly different, it is easily determined that the image is forged or tampered with.

Further, regarding a pattern or the like on the facing paper printed with different colors for each part, some of the parts etched with a laser beam can be seen in the above colors when observed with visible light. When irradiated with ultraviolet light, the above-mentioned etched portion develops one color. Therefore, even if printing is artificially printed on the facing paper in different colors for each part as in the case of the genuine valuable printed matter, the authenticity can be easily determined by irradiating the laser beam.

(Embodiment 2) FIGS. 4 to 7 are views for explaining Embodiment 2 in which the valuable printed material according to the present invention is applied to a passport booklet. The calf 2 which is the cover of the passport booklet as in Example 1.
And the facing paper 3 on which personal information is printed with a black ink are adhered with an adhesive, and a laminating film 6 is laminated thereon. However, while the passport booklet 1 according to the first embodiment is irradiated with the laser beam 8 after being laminated, the passport booklet 11 according to the second embodiment is that the laser beam 8 is irradiated before being laminated, and The film 6 is different from that of the first embodiment in that the film 6 is made of a material that is thin or has a high ultraviolet transmittance so that it can transmit ultraviolet rays.

Specifically, in Example 2, wet offset printing was performed using the same ink as in Example 1, and then the same carbonic acid as that used in Example 1 was applied to a part or the entire surface of this printing surface. As shown in FIG. 4, the laser beam 8 is emitted by the gas laser marker 7 at an output of a laser power of 30%. After that, by laminating the laminating film 6, the passport booklet 11 shown in FIGS. 5 and 6 is manufactured. The laminate film 6 is formed of a material having an original protective function and being thin or having a high ultraviolet transmittance so that it can transmit ultraviolet rays.

When the passport booklet 11 is checked, it is irradiated with ultraviolet rays 10 as shown in FIG. As in Example 1, the ink of the print 5 on the print surface is affected by the heat of the laser beam 8, and the print 5 looks black under visible light as in the case where the laser beam is not irradiated. When it is irradiated with ultraviolet rays 10, it develops color with light having a red wavelength outside the ultraviolet range. As a result, the passport booklet 11 of the second embodiment is also provided with the function of preventing forgery and falsification.

By the way, in Example 2, when the laminated film has a thickness normally used in a passport booklet, that is, when it is not formed of a material that is thin or has a high ultraviolet transmittance enough to transmit ultraviolet rays, Print 5
Does not develop a red color as described above even when irradiated with ultraviolet rays 10. It is considered that this is because ultraviolet rays are absorbed by the laminate film and do not penetrate to the printed surface. By the way, in the case where a groove is formed by irradiating a laser beam after laminating as in Example 1, the laminate film disappears or becomes thin, and irradiated ultraviolet rays are easily transmitted, so that the problem that the print 5 does not develop color does not occur. .

As described above, in the valuable printed matter according to the second embodiment, the laminated film 6 needs to be limited to a material having a high thickness or a high ultraviolet ray transmissivity to the extent that ultraviolet rays can be transmitted. Since it is easy to determine that it is not genuine other than such a limited laminated film, the effect of preventing forgery and falsification is extremely large.

(Third Embodiment) Although not shown in the drawings, a third embodiment in which the valuable printed matter according to the present invention is applied to a bill will be described. This banknote uses the carbon dioxide laser marker used in Example 1 on a part or all of the printing surface of the base material printed with the wet offset ink to scan at a scanning speed of 20.
A laser beam is emitted at 0 and a laser power of 15%. The wet offset ink is not a special ink containing a fluorescent substance or the like, but a purple ink containing 10% of phthalocyanine blue H, which is a coloring pigment, 20% of quinacridone red Y, and 70% of varnish for wet offset is used. .

Then, when checking a bill that has undergone the laser beam irradiation process in this way, it is irradiated with ultraviolet rays. Similar to the first and second embodiments, the ink on the printed surface is thermally affected by the irradiation of the laser beam, and it looks like the color tone under visible light when the ink is not irradiated with the laser beam. When irradiated with, it develops color with light of an orange wavelength other than ultraviolet light, and looks orange.

As described above, the point to make the ink look orange under ultraviolet rays is to mix the ink with quinacridone red Y. As a coloring pigment, phthalocyanine blue was blended, but the color observed with visible light is
It can be changed by blending with other coloring pigments. When the wet offset ink blended with the dioxazine violet used in Example 1 is used, it looks red under UV irradiation.

If the printing surface of the banknote as in this Embodiment 3 is previously irradiated with a laser beam of a predetermined intensity at the time of issuance or the like, the true / false judgment is made by irradiating this printing surface with ultraviolet light to develop the color. By checking, it is possible to easily determine the authenticity. Recently, printing technology using copiers and personal computers has become easier and more advanced, but even if these printing technologies are used,
According to this embodiment, authenticity can be easily determined, and forgery and falsification can be effectively prevented.

In the second and third embodiments, the laser beam is directly radiated on the printing surface. In this case, the laser beam is radiated only on a part of the print to give a thermal effect, so that this character is printed. Even if the whole character looks the same color when viewed with visible light, it is possible to make only a part of the character develop a different color when irradiated with ultraviolet rays. By doing so, even if a laser beam is applied to a forged or falsified printed surface, it is extremely difficult to affect a part of the characters with heat just like a genuine valuable printed matter, and if ultraviolet rays are applied, Since the portion of the same character that is colored in a different color is slightly different from that of the genuine valuable printed matter, it is easily determined that the forgery or tampering has occurred.

Similarly, regarding Examples 2 and 3, when a pattern printed in a different color for each part was irradiated with a laser beam on some parts and the pattern was observed with visible light, the above-mentioned respective parts were observed. Although visible in color, when irradiated with ultraviolet light, the part irradiated with the laser beam develops one color. In this way, even if the parts are printed in different colors and laser beam irradiation processing is performed in the same way as in the case of a genuinely precious printed matter, the pattern of the above pattern is exactly the same as in the genuine precious printed matter. It is extremely difficult to give a heat effect to the part, and the parts that develop different colors are slightly different. Therefore, it is easy to determine that the image is forged or tampered with by irradiating with ultraviolet rays.

(Embodiment 4) FIGS. 8 to 9 are views for explaining Embodiment 4 in which the valuable printed material according to the present invention is applied to a passport booklet. In FIG. 8, a kerf (mounting sheet) 2 which is the cover of the passport booklet 12 and a facing sheet (base material) 3 on which personal information is printed with black ink are vinyl acetate adhesive 1
It is glued at 3. The return sheet 3 is a laser beam 8
The surface 15 of the vinyl acetate-based adhesive 13 inside thereof is substantially exposed, and the surface 15 is thermally affected by the laser beam 8 to be altered. .

Then, the laminate film 16 is laminated on the surface of the facing paper 3 to form the passport booklet 12 as shown in FIG. This laminated film 16
Is formed of a material that is thin or has a high ultraviolet transmittance that allows ultraviolet rays to pass therethrough without impairing the protective function.

Specifically, the same carbon dioxide laser marker as in Example 1 was used to scan a part or the whole surface of the facing sheet 3 with a scanning speed of 500 mm / sec and a laser power of 30 to 30.
The laser beam 8 is irradiated at an output of 40% to irradiate the facing paper 3 with a specific pattern so as to disappear. Then, the laminated film 16 is laminated on the facing paper 3 to manufacture the passport booklet 12.

Then, when checking such a passport booklet 12, the ultraviolet rays 10 are irradiated as shown in FIG. The surface 15 of the vinyl acetate-based adhesive 13 which is exposed to the heat of the laser beam 8 and which is almost exposed in a pattern,
Although it can be seen under visible light without any change, ultraviolet rays 10
When it is irradiated with, the color of light having a wavelength of yellow-green outside the range of the ultraviolet rays 10 is developed, and the light appears yellow-green. As a result, this passport booklet 1
The authenticity of 2 is easily determined, and the function of preventing forgery and falsification is added. It should be noted that, for example, a modified example in which the laminate is not always necessary depending on the application, such as a disposable introductory certificate, is conceivable.

(Fifth Embodiment) FIG. 10 is a diagram for explaining a fifth embodiment of a valuable printed material according to the present invention. This valuable printed matter 17 is a paper 18 on which personal information is printed with ink.
A vinyl acetate emulsion layer 19 is coated or printed on the surface of the vinyl acetate emulsion, and the surface of the vinyl acetate emulsion layer 19 is formed by irradiating the surface with the laser beam 10 in a specific pattern. This laser beam 1
By irradiation of 0, the layer 19 is affected by heat and deteriorates. The valuable printed matter 17 is placed in the layer 1 according to its use, such as being put in and taken out of a device such as a depositing machine such as a bank card.
The surface of 9 may be laminated with a thin laminating film as shown in Example 4.

When the surface of the valuable printed matter thus formed is irradiated with ultraviolet rays, the portion of the vinyl acetate emulsion layer affected by the heat of the laser beam is the portion not irradiated with the laser beam under visible light. When it is irradiated with the above-mentioned ultraviolet rays, it is colored with light of a yellow-green wavelength outside the ultraviolet range and appears yellow-green. As a result, the valuable printed matter is provided with the function of preventing forgery and falsification.

[0054]

As described above, according to the present invention, a valuable printed matter obtained by a very low cost and simple process of irradiating a printing surface with a laser beam without using a fluorescent substance-containing ink is provided. The printed portion of the printed surface can be colored with a color different from that when it is irradiated with ultraviolet rays and observed with visible light, and it is possible to easily judge the authenticity by observing this color.

Then, for a valuable printed matter obtained by irradiating the surface of the laminate film with a laser beam to etch the grooves to heat the print surface of the paper, the print surface is forged or tampered with and the laminate film is simply attached. Even if the groove is changed or machined on this laminated film, the laser beam is not irradiated and the ink on the printed surface is not affected by heat. Even if the groove is etched by irradiating the laser beam. Since it is difficult to make the position and etching depth exactly the same as the authentic one, it is possible to easily determine the authenticity only by irradiating this with ultraviolet rays.

The valuable printed matter of the present invention, which is constructed by irradiating a laser beam in a specific pattern on a paper adhered with a vinyl acetate adhesive or a paper on which a vinyl acetate emulsion layer is formed, is visible. Although the color does not change with light, when it is irradiated with ultraviolet light, it develops a color different from that observed with visible light, so that forgery and tampering can be easily determined, and it has a great effect on forgery and tampering prevention.
