That is, the present invention relates to a forgery-preventing printed material having a cut portion or a through hole in a base material, and the cut portion or the through hole has a shape cut in an oblique direction with respect to the thickness direction of the base material. The anti-counterfeit printed matter is characterized in that non-impact recording is performed from the cut surface of the base material to a portion including the cut surface or the processed surface of the through hole. As a result, the forgery-preventing printed matter can read the unique information by non-impact recording when observing the cut portion or the through-hole from an oblique direction having a predetermined angle with respect to the thickness direction of the substrate. When the anti-counterfeit printed matter is observed in a direction different from the thickness direction of the base material or the predetermined oblique direction, the information by the non-impact recording cannot be read.

  Further, the present invention provides a method for producing a forgery-proof printed matter by performing processing for forming a cut portion or a through-hole by laser irradiation on a base material for preventing forgery and then performing non-impact recording. The laser irradiation condition is that the laser irradiation is performed in an oblique direction that is a predetermined angle with respect to the thickness direction of the base material, and the cutting portion or the through hole is set at a predetermined angle with respect to the thickness direction of the base material. The method for producing a forgery-preventing printed matter is characterized in that the non-impact recording is performed on the portion including the cut surface or the processed surface of the through hole. According to this manufacturing method, when forming a cutting part or a through hole by laser irradiation, the processing position and processing depth can be easily changed by changing the laser irradiation conditions, resulting in anti-counterfeiting properties. Can be high. Further, by observing the cut portion or the through-hole from an oblique direction having a predetermined angle with respect to the thickness direction of the base material, it is possible to easily obtain a forgery-preventing printed material from which unique information by non-impact recording can be read.

  Further, in the method for producing a forgery-preventing printed material according to the present invention, the base material is prepared as a continuous sheet, the processing region of the continuous sheet is suspended and supported, and the supporting portion is moved to move the continuous sheet. In this processing region, the continuous sheet is inclined at a predetermined angle with respect to any direction including the width direction and the conveyance direction, and laser cutting is performed to form a cutting portion or a through hole in the base material. To do. Thereby, a cutting part or a through-hole can be formed accurately and stably.

  Moreover, the manufacturing method of the said forgery prevention printed matter is characterized by forming a cutting part or a through-hole inclined in two or more different angles with respect to the thickness direction of the said base material. Thereby, the forgery prevention property of the information recorded on the cut surface or the processed surface of the through hole is further enhanced.

  In addition, the method for producing a forgery-preventing printed material according to the present invention is characterized in that the cutting portion or the through hole is formed with an inclination of ± 45 ° or more with respect to the thickness direction of the substrate. The anti-counterfeit printed matter obtained in this way has a through hole formed, and it is difficult to confirm the transmitted light from the back side, and the anti-counterfeiting property is further improved.

  The anti-counterfeit printed matter of the present invention has an advanced anti-counterfeiting technology that has never existed in the past by adopting the above configuration. Further, according to the method for producing a forgery-preventing printed material of the present invention, a cutting portion or a through hole can be accurately and stably formed on the base material of the forgery-preventing printed material.

It is sectional drawing which shows other embodiment which is a forgery prevention printed matter of this invention. It is sectional drawing which shows other embodiment which is a forgery prevention printed matter of this invention. It is the schematic which showed the example which forms a cutting part or a through-hole in the base material of the manufacturing method of the forgery prevention printed matter of this invention. When the laser beam is irradiated in an oblique direction that is a predetermined angle with respect to the thickness direction of the base material, and the cut part or the through hole is formed at a predetermined angle with respect to the thickness direction of the base material, the inclination is inclined. It is the schematic explaining the meaning of plus and minus of an angle.

Next, embodiments of the present invention will be described in detail. The anti-counterfeit printed matter and the manufacturing method thereof shown in the following embodiments are also examples of the present invention.
In FIG. 1, one embodiment which is the forgery prevention printed matter 1 of this invention is shown. A through hole 3 is provided in the base material 2, and the through hole 3 has a shape cut in an oblique direction with respect to the thickness direction of the base material 2. That is, it has the through-hole 3 cut | disconnected in the diagonal direction which is the inclination | tilt angle (alpha) with respect to the thickness direction of the base material 2. As shown in FIG. Further, the non-impact recording portion 5 is formed by performing non-impact recording from the cut surface 12 of the base material 2 to the portion including the processed surface 4 of the through hole 3. When the anti-counterfeit printed matter 1 in FIG. 1 is observed from the front, an image interrupted by the through hole 3 in the non-impact recording portion 5 is seen, but cannot be recognized as a complete image. On the other hand, when the anti-counterfeit printed matter 1 is observed from the A direction that is a cut oblique direction with respect to the thickness direction of the base material 2, an image A recorded non-impact on the processed surface of the through-hole 3 appears. This image A is a complete image and can be recognized as a genuine product.

  FIG. 2 is a cross-sectional view showing another embodiment of the anti-counterfeit printed matter 1 of the present invention. The substrate 2 is provided with three holes 31, 32, and 33, and all the through holes are The through-hole 31 and the through-hole 32 have the same inclination angle, and the through-holes 31 and 32 are the same. And the inclination angle by which the through-hole 33 was cut differs.

  In addition, all the three through-holes 3 in the forgery prevention printed matter shown in FIG. As will be described later with reference to a method for manufacturing a forgery-preventing printed matter, if the inclination angles are all the same in processing the through-hole or the cut portion, the setting conditions for processing are simple and easy to manufacture. However, in terms of anti-counterfeiting measures, it is preferable to change the inclination angle at which the through hole or the cutting portion is processed as shown in FIG. That is, when the anti-counterfeit printed matter 1 shown in FIG. 2 is observed from the front, an image interrupted by the through-hole 3 in the non-impact recording portion 5 is seen, but cannot be recognized as a complete image. On the other hand, when the anti-counterfeit printed matter 1 is observed from the A direction which is a cut oblique direction with respect to the thickness direction of the base material 2, an image A recorded non-impact on the processed surfaces of the through holes 31 and 32 is obtained. Appearing, this image A is a complete image and can be recognized as a genuine product. At that time, the image B by non-impact recording formed on the processed surface of the through-hole 33 cannot be recognized.

  Further, when the anti-counterfeit printed matter 1 is observed from the B direction different from the A direction which is an oblique direction cut with respect to the thickness direction of the base material 2, the processed surface of the through hole 33 is observed. A non-impact recorded image B appears, and this image B is a complete image and can be recognized as a genuine product. At that time, the image A by non-impact recording formed on the processed surfaces of the through holes 31 and 32 cannot be recognized. Therefore, when the anti-counterfeit printed matter 1 as shown in FIG. 2 is observed in different directions as shown in the A direction and the B direction, the non-impact recorded image on the processed surface of the through-hole or the cutting portion changes. High anti-counterfeiting property.

  FIG. 3 is a cross-sectional view showing another embodiment of the anti-counterfeit printed matter 1 of the present invention, in which a cutting portion 6 is provided on the base material 2, and the cutting portion 6 has a thickness of the base material 2. The shape is cut in an oblique direction with respect to the direction. That is, it has the cutting part 6 cut by the diagonal direction which is the inclination | tilt angle (alpha) with respect to the thickness direction of the base material 2. FIG. In addition, a non-impact recording portion 5 is provided in a portion including the machining surface 4 of the cutting portion 6. When the anti-counterfeit printed matter 1 in FIG. 3 is observed from the front, an image interrupted by the cutting portion 6 in the non-impact recording portion 5 is seen, but cannot be recognized as a complete image. On the other hand, when the anti-counterfeit printed matter 1 is observed from the A direction that is a cut oblique direction with respect to the thickness direction of the base material 2, an image A non-impact recorded on the processed surface 4 of the cutting portion 6 appears. Thus, this image A is a complete image and can be recognized as a genuine product.

  The difference between the cutting part 6 and the through hole 3 is that the through hole is cut from the surface of the base material to the back surface, and the cut part is cut from one surface of the base material, It is processed to the middle of the thickness direction of the base material without cutting and penetrating the other surface of the base material. FIG. 1 and FIG. 3 show only the difference between the through hole 3 and the cutting part 6, and there is no difference in the number (3) processed and the inclination angle in the processed through hole or cutting part. In the example in which the inclination angle as shown in FIG. 2 is changed, the through hole can be replaced with a cutting portion. Furthermore, the state recognized when observing the non-impact recording part shown in FIGS. 1 and 2 from the front and when observing from the oblique direction (A direction) cut with respect to the thickness direction of the substrate 2 is The same applies to the case of FIG.

Below, the element which comprises the forgery prevention printed matter of this invention is demonstrated in detail.
(Base material)
Examples of the base material 2 of the anti-counterfeit printed material include paper such as high-quality paper, art paper, coated paper, cast coated paper, synthetic resin or emulsion-impregnated paper, synthetic rubber latex-impregnated paper, synthetic resin internal paper, and cellulose fiber paper , Plastic sheets of various synthetic resins such as polyolefin (polyethylene, polypropylene, etc.), polystyrene, polycarbonate, polyethylene terephthalate, polyvinyl chloride, polymethacrylate, etc., and white films formed by adding white pigments and fillers to these synthetic resins An opaque film or a film (so-called synthetic paper) having fine voids inside the substrate can be used.

  However, it is necessary to perform non-impact recording on the anti-counterfeit printed matter and to secure a predetermined thickness that can form a cut portion or a through hole. For example, among the above-mentioned base materials, papers having a thickness of 20 to 300 μm are preferable.

(Non-impact recording)
Non-impact recording methods include, for example, electrophotographic recording, ink jet recording, melt transfer recording, sublimation transfer recording, and the like. In the present invention, non-impact recording is performed on a part including the machining surface of the cutting part or the through-hole, but the machining of the cutting part or the through-hole changes the machining position and machining depth by laser irradiation as appropriate. Correspondingly, the position of non-impact recording and the information of recording can be changed as appropriate, and the anti-counterfeiting property is improved. Further, in the present invention, since non-impact recording is performed on the cutting portion or the portion including the processed surface of the through hole, high-definition and variable information can be recorded, and further, recording is performed on the surface of the substrate. What has penetrated into the inside of the substrate is preferable. As a recording method in response to this requirement, an ink jet recording method can be cited. Also, as an ink jet ink used for ink jet recording even in ink jet recording, as a colorant, which is easily dissolved in a solvent, a dye type is used. Is particularly preferred.

Below, the manufacturing method of a forgery prevention printed matter is demonstrated.
This is a method for producing anti-counterfeit printed matter by forming a cutting part or through-hole by laser irradiation on the base material of the anti-counterfeit printed matter and then performing non-impact recording to produce the anti-counterfeit printed matter. The condition is that laser irradiation is performed in an oblique direction that is a predetermined angle with respect to the thickness direction of the base material, and the cut portion or the through hole is formed at a predetermined angle with respect to the base material thickness direction. The non-impact recording is performed on the cutting portion or the portion including the processed surface of the through hole.

  When processing the cutting part or the through hole of the anti-counterfeit printed matter, the relationship between the orientation of the base material of the anti-counterfeit printed matter and the direction of the laser irradiation, the cutting part or the through hole is relative to the thickness direction of the base material, It adjusts so that it can process so that it may have the shape cut in the diagonal direction. For example, as shown in FIG. 4, the base material 2 is prepared as a continuous sheet, the processing region of the continuous sheet is suspended and supported, and the supporting portions (7, 8, 9, 10) for supporting are illustrated. As shown by the arrows, the laser irradiation means 11 irradiates the continuous sheet at a predetermined angle with respect to any direction including the width direction and the conveyance direction in the processing region of the continuous sheet. Thereby, it is possible to form a cutting part or a through-hole in the base material 2. Said support parts 7 and 9 are the parts which support the both ends of a common roll, and the conditions which both move are the same or different. Moreover, said support parts 8 and 10 are the parts which support the both ends of a common roll, The conditions to which both are movable may be the same or different.

  In the above example, it is a case of a continuous sheet that is long as a base material, but is not limited thereto, and a sheet-like sheet as a base material, the sheet is installed on a flat base, and the flat base is inclined at a predetermined angle. It is also possible to form a cutting part or a through hole by laser irradiation. In addition, when mass-producing anti-counterfeit printed matter, the base material is a continuous sheet. It is preferable to form a cutting part or a through hole by a method as shown in FIG.

  As the laser irradiation means, YAG laser, carbon dioxide laser, ruby laser, etc. are used as laser light, and in particular, YAG laser has a short wavelength and can be focused on a minute spot, so finer processing is possible. Preferably used. A laser irradiation means can form a cutting part or a through-hole with an arbitrary shape and depth.

An example of the laser irradiation means applied in the present invention will be described. First, the laser light is condensed by a lens, and the surface of the base material is irradiated onto the anti-counterfeit printed matter. At that time, the cutting depth can be adjusted by changing the laser light irradiation time or the laser output value. That is, when the laser beam irradiation time is short, the cutting portion becomes shallow, the laser beam irradiation time can be increased, the cutting portion can be deepened, and a through hole can be formed. Further, when the laser output value is small, the cutting portion becomes shallow, the laser output value is increased, the cutting portion is deepened, and the through hole can be formed. In this way, it is possible to easily perform cutting with high accuracy, good reproducibility, and non-contact with the processing region.

  The laser irradiation means of the present invention preferably uses a laser beam in an infrared region of about 0.9 to 11 μm, and the portion irradiated with the laser light is heated. The portion irradiated with the laser light is locally heated and cut by blowing off the portion in the liquid phase in a state exceeding the melting point of the portion, thereby forming a cut portion or a through hole.

  In the above laser irradiation means, when setting or changing the formation position of the cutting part or the through hole, the laser irradiation device is conveyed in the width direction as shown in FIG. It can be moved in any direction such as a direction. Or the base material of a forgery prevention printed matter can also be moved to arbitrary directions. For example, an anti-counterfeit printed material as shown in FIG. 2 is obtained in which it is preferable to form a cutting part or a through hole by inclining at two or more different angles with respect to the thickness direction of the base material of the anti-counterfeit printed material. be able to. Further, it is preferable to form the cut portion or the through hole by inclining ± 45 ° or more with respect to the thickness direction of the base material. As a result, it becomes difficult to confirm the transmitted light from the back surface side in a state where the through hole is formed, so that the forgery prevention property is further improved.

  In the present invention, it has been explained that it is preferable to form a cutting part or a through hole by inclining ± 45 ° or more with respect to the thickness direction of the base material. As shown in FIG. 5, minus is defined as a positive angle in the clockwise direction and a negative angle in the counterclockwise direction with respect to the thickness direction of the substrate. Therefore, the cutting part or the through-hole provided in the forgery-preventing printed matter is inclined from + 45 ° to less than + 90 °, and further from −45 ° to less than −90 °, when inclined by ± 45 ° or more with respect to the thickness direction of the substrate. Means that.
