SECURE PRINTED MATTER

The present invention relates to a printed matter and a method of manufacturing the same, and more particularly, to a security printed matter printed with multiple security elements and a method of manufacturing the same.

A variety of security printing has been proposed in the past to protect money, securities, identification cards and various security documents from counterfeit or fraudulent production. In the security printing field, inks having various functions or special printing patterns are used for the purpose of preventing forgery of documents or products and facilitating genuine product authentication. However, in general, the security element is implemented in a simple way of a 1:1 correspondence concept that applies one security ink to one printing method to check the effect, or from a design point of view, visible light conditions such as a transient image. Attempts have been made to diversify recognition patterns in

As the performance of computers, scanners, and copiers has recently improved, the demand for secure printing for product authentication and anti-counterfeiting of money, securities, identification cards and various security documents is increasing. There is a need to develop printing.

Figure 2b is a cross-sectional view in which the near-infrared ink layer of the present invention is laminated on one surface of the printed layer. 3 is a cross-sectional view of a security print according to another embodiment of the present invention according to the present invention. Hereinafter, descriptions of previously known matters will be omitted or simplified in order to clarify the gist of the present invention.

1 to 3, the security printed material 1 according to the present invention may be formed with multiple security elements, and thus, it is possible to increase security and prevent forgery at the same time. The security print 1 may include a base layer 100 , a printing layer 200 , a stereogram layer 300 , a near-infrared ink layer 400 , a fluorescent ink layer 500 , and an adhesive layer 600 .

The base layer 100 may have a printed layer 200 , a stereogram layer 300 , a near-infrared ink layer 400 , and a fluorescent ink layer 500 laminated on one side, and an adhesive layer 600 on the other side. It can be adhered to other printed matter or objects by Accordingly, the security print 1 may be used as an activation tape or an activation sticker.

Here, the base layer 100 may be made of a paper material, and the security print 1 in which the base layer 100 is formed of a paper material is recycled by not having a layer formed of a film on one side and the other side of the base layer 100 . It can be easy.

The printing layer 200 may be laminated on one surface of the base layer 100 , and a general image may be printed thereon. The ink printed on the printing layer 200 may be carbon-free imitation black ink prepared by mixing C/M/Y inks except for K ink containing carbon among C/M/Y/K inks, If a normal image is printed using imitation ink, the imitation ink excluding carbon may be lost when checked with a near-infrared view.

Here, the imitation ink is not limited to black, and carbon-free inks that can be prepared by mixing C/M/Y inks may be substituted with other colors.

The stereogram layer 300 may be laminated on one surface of the printing layer 200 from one surface of the base layer 100, and a holographic stereo film on which a stereogram is recorded or a holographic stereo film on which a stereogram is recorded. A stereogram moving along the light source may be formed by pressing and then removing the printed layer 200 using an embossing transfer method.

Here, when the base layer 100 is made of paper, the security print 1 finally manufactured by pressing and then removing the holographic stereo film on which the stereogram is recorded using the emboss transfer method does not contain a film. It is a print made of pure paper material that is not made of pure paper, and can be recycled, and when the security print 1 is attached to a curved surface, separation of paper and film can be fundamentally eliminated. In addition, the thickness of the final security print 1 becomes thinner by removing the holographic stereo film on which the stereogram is recorded by pressing and removing it using the emboss transfer method, so the weight of the print 1 of the same length is wound on a roll. can be reduced to facilitate transport, and when the printed material 1 is wound on a roll with the same thickness, the length of the wound printed material 1 increases, thereby extending the roll replacement time in the manufacturing operation, thereby improving productivity.

The near-infrared ink forming the security element in the near-infrared ink layer 400 can be prepared by mixing a transparent pigment and a near-infrared absorbing pigment, and when the transparent pigment and the near-infrared absorbing pigment are mixed to improve transparency, the ratio of the transparent pigment to the near-infrared absorbing pigment This could be higher.

At this time, when photographing with the near-infrared view, the general image of the printed layer 200 printed with the carbon-free imitation ink may be lost, and only the security element formed of the near-infrared ink may be identified. In addition, in the visible region, only the general image printed with the imitation ink can be visually recognized, and the security element formed with the near-infrared ink can be hidden.

In addition, the near-infrared ink layer 400 may be laminated on one surface of the printing layer 200 , the stereogram layer 300 , or the fluorescent ink layer 500 on one surface of the base layer 100 . That is, when the general image printed on the printing layer 200 is printed with imitation ink, the general image is lost when confirmed with a near-infrared view, and only the security element using the near-infrared ink is checked, so that the near-infrared ink layer 400 is stacked in the order of can be formed regardless of

Here, the fluorescent ink may be an ink in which at least one or more fluorescent inks emitting light at different wavelengths are mixed. For example, pigments of different colors can be identified by irradiating light suitable for wavelength by forming a security element with ink mixed with pigments emitting light at 365 nm and 254 nm. In addition, when the color of the ink forming a general image in the printing layer 200 is low in the fluorescent ink layer 500 , a security element formed of the fluorescent ink may be laminated on the other surface of the printing layer 200 .

According to the above, it is possible to improve security and prevent forgery of the security printed matter 1 by arranging multiple security elements.

The adhesive layer 600 may be selectively laminated on the other surface of the base layer 100 and may be formed of an adhesive. Accordingly, when the adhesive layer 600 is formed on the other surface of the base layer 100, the security print 1 is formed of a tape or sticker on which a security element is printed, and can be attached to other objects or prints as an activation print, If the adhesive layer 600 is not formed, the security element may be used as a printed activation document.

Next, the stereogram layer 300 may be formed by removing the holographic stereogram film compressed on the printing layer 200 (S40), and a security element using near-infrared ink is applied to one surface of the stereogram layer 300. The formed near-infrared ink layer 400 may be stacked (S50). In this case, the near-infrared ink may be prepared by mixing the transparent pigment and the near-infrared absorbing pigment, and when the transparent pigment and the near-infrared absorbing pigment are mixed to improve transparency, the ratio of the transparent pigment to the near-infrared absorbing pigment may be higher. In addition, when a general image printed on the printing layer 200 is printed with imitation ink, the near-infrared ink layer 400 is a printing layer 200 , a stereogram layer 300 or a fluorescent ink layer on one surface of the base layer 100 . It may be laminated on one surface of 500 . That is, when checking with the near-infrared view, the general image is lost and only the security element using the near-infrared ink is checked, so that the near-infrared ink layer 400 may be formed regardless of the stacking order.

Next, fluorescent ink may be manufactured (S60), and a fluorescent ink layer 500 in which a security element using fluorescent ink is formed may be laminated on one surface of the near-infrared ink layer 400 (S70).

Here, the fluorescent ink may be an ink in which at least one or more fluorescent inks emitting light at different wavelengths are mixed. For example, pigments of different colors can be identified by irradiating light suitable for wavelength by forming a security element with ink mixed with pigments emitting light at 365 nm and 254 nm. In addition, when the fluorescent ink layer 500 has a low saturation of ink forming a general image on the printing layer 200 , the printing layer 200 is printed on one surface of the base layer 100 for the security element formed of the fluorescent ink. It can be preceded by a step.

Finally, an adhesive layer may be selectively formed on the other surface of the base layer 100 (S80). Accordingly, when the adhesive layer 600 is formed on the other surface of the base layer 100, the security print 1 is formed of a tape or sticker on which a security element is printed, and can be attached to other objects or prints as an activation print, If the adhesive layer 600 is not formed, the security element may be used as a printed activation document.

Hereinafter, a method of manufacturing a security print according to a preferred embodiment of the present invention will be described in detail with reference to the drawings. 5 is a flowchart of a method for manufacturing a holographic stereogram film forming a stereogram layer according to the present invention. Hereinafter, descriptions of previously known matters will be omitted or simplified in order to clarify the gist of the present invention.

Next, a plurality of hogels, which are holographic elements (hologram elements) constituting a holographic stereogram, can be generated through pixel rearrangement (S23), and object light can be set using information of hogels for each hogel. (S24). Next, a fringe pattern may be generated in units of several hundred nanometers by calculating the interference between the object light and a preset reference light (S25), and the generated fringe pattern may be recorded in a medium to manufacture an original plate (S26). The surface of the medium on which the fringe pattern is recorded can be surface-treated with oxide (S27), and the surface-treated original plate can be used to replicate it on a film plate (S28). Finally, the film plate duplicated by the original plate can be transferred to the film (S29). Accordingly, a plurality of holographic stereogram films can be produced.
