Description

The present invention relates to a printed matter and a printing method, and relates to, for example, a printed matter in which product information including legally displayed information of the product and product identification information assigned to the product are printed and a printing method of the printed matter.

In recent years, there have been widespread cases of illegally reselling products such as high-end shampoos and cosmetics on websites on the Internet by removing the serial number (product identification information), cutting it out, or painting it with magic. .. The product serial number (product identification information) is, for example, printed on a label (or the product container itself) affixed to the product or product container after being converted into a QR code (registered trademark) or the like. The act of scraping, cutting, or painting the QR code with magic and then illegally reselling it on the Internet has become a problem.

The QR code indicating the serial number of the product is used by the manufacturer / seller of the product to manage the product number, the expiration date, and the delivery destination information for each product. Specifically, the manufacturer / distributor reads the QR code before shipping the product, associates the product number and expiration date of each product with the delivery destination information of the product, and registers and manages the product in a database or the like. Further, even in the distribution process, the distributor who sells the product reads the QR code, so that the distribution status of the product can be grasped.

However, if the above QR code is deleted and illegally resold, it becomes difficult to know when and where the product was manufactured, and there is a risk that quality cannot be guaranteed. Further, if the above QR code is deleted, it becomes impossible to investigate the sales route of illegal resale, and there arises a problem that countermeasures against illegal resale cannot be taken.

As a method for countering the above-mentioned illegal resale, Patent Document 1 discloses an invention of an exterior sheet attached to an outer peripheral surface of a product container.
Specifically, the above-mentioned exterior sheet displays a normal print layer that displays product information including the legal display of the product on the sheet material, and an ID figure (two-dimensional code) that makes the product identification information decodable by a device. A basic print layer composed of an ID print layer is provided. This basic print layer is visible from the outer surface side of the exterior sheet. Further, the exterior sheet is provided with a secret printing layer that displays an ID symbol that makes it possible to visually read the product identification information at a position on the back surface side inside the basic printing layer and not overlapping the ID figure. .. Further, a masking print layer is provided between the secret print layer and the basic print layer. The secret print layer is invisible from the outer front surface side of the exterior sheet due to the masking print layer, and is visible from the back surface side inside the exterior sheet.

Further, the above-mentioned exterior sheet is manufactured by the following method.
First, a secret printing layer displaying an ID symbol is printed on the outer surface of a sheet material formed of a transparent film. This ID symbol is composed of symbols such as English letters and number letters so that the serial number of the product can be read immediately by visual inspection, and when visually recognized from the outer surface side F, it has a mirror symmetry. It is printed as a symbol represented by. As a result, the ID symbol can be read immediately when it is visually recognized from the back surface side of the sheet material.
Next, the masking print layer is printed on the secret print layer. The masking print layer is for concealing the secret print layer from the outer surface side, and if necessary, printing is performed in layers so as to form a plurality of layers. Next, the basic print layer is printed on the masking print layer. An adhesive layer is provided on the inner back surface of the sheet material.

The exterior sheet is used by being attached to the outer peripheral surface of a product container such as an opaque bottle, and a secret printing layer displaying an ID symbol is printed behind the masking printing layer. Therefore, during the distribution of the product, the ID symbol is concealed so that it cannot be visually recognized from the outer surface side of the exterior sheet. Therefore, an unauthorized distributor who distributes goods in the distribution process cannot recognize the existence of the ID symbol.
In addition, even if an illegally distributed product with the ID figure visible from the front surface side of the exterior sheet deleted, such as by cutting off a part of the exterior sheet, if the exterior sheet is peeled off from the repaired illegally distributed product, the ID symbol on the back surface will be displayed. Can be read, and the cause of unauthorized distribution can be investigated. At this time, since the ID symbol does not require a reader device and the identification information can be read only visually, the investigation can be started immediately and the cause can be investigated at an early stage.

Japanese Patent No. 6560711

By the way, as for the exterior sheet described in Patent Document 1 described above, when an illegally distributed product in which an ID figure visible from the surface side of the exterior sheet is deleted occurs, the illegally distributed product is obtained, and the exterior sheet is obtained from the illegally distributed product. By peeling off, the ID symbol can be seen from the back surface of the exterior sheet. However, in such a case, it is necessary to peel off the exterior sheet from the illegally distributed product so that the exterior sheet is not torn, and there is a problem that the confirmation work is troublesome. This is because if the exterior sheet peeled off from the illegally distributed product is torn, the ID symbol on the back surface may not be readable.
Further, the exterior sheet described in Patent Document 1 is intended to be used for a product container such as an opaque bottle, and has a problem that it cannot be used for a container such as a transparent bottle. When the exterior sheet is attached to a product container such as a transparent bottle, the back surface of the exterior sheet can be seen from the opposite side of the attached exterior sheet. This is because the existence of the symbol can be recognized.
In addition, some products have product information and ID figures (product identification information) printed directly on the product container, but in the above-mentioned exterior sheet, the product information and ID figures (product identification information) are directly printed on the product container. It cannot be applied to those that print product identification information).

Further, in the exterior sheet described in Patent Document 1 described above, an ID symbol is printed on a sheet material formed of a transparent film, a masking printing layer is printed on the ID symbol, and further, a masking printing layer is printed on the masking printing layer. , It is necessary to print a basic printing layer including a legal display of a product, and there is a technical problem that the number of steps is large and the cost is increased.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a printed matter at low cost, which can easily prevent unauthorized distribution of goods and investigate the cause. The present invention also provides a printing method for the printed matter.

The present invention for solving the above technical problems is a printed matter in which various information is printed on one side of a base material, and product information including legal display information obliged to be displayed on a product is visible ink. The product information display unit printed in 1 is formed, and the product identification information uniquely assigned to the product is printed with invisible ink on the product information display unit, and overlaps with the product information display unit. At least the two-dimensional code information shown by converting the information including the product identification information into the two-dimensional code is printed in the visible ink in the non-visible area, and the product identification information printed by the invisible ink is the product identification information. The feature is that it is printed on top of the legally displayed information .
In addition, the statutory labeling information is based on the labeling stipulated by the Act on Securing Quality, Effectiveness and Safety of Pharmaceuticals, Medical Devices, etc., the Fair Competition Code on Cosmetic Labeling, Unfair Gifts and Unfair Labeling Prevention Law. It is desirable that the specified indication is included.

According to the above configuration, when the printed matter of the present invention is distributed so as to be integrated with the product, that is, the printed matter of the present invention is attached to the product (or the container of the product), or is placed in the container of the product. When a product is distributed by forming a printed matter of the present invention, an unauthorized distributor cannot recognize the product identification information printed with invisible ink in the product distribution process.
The product identification information printed with invisible ink is radiated and colored by irradiating it with ultraviolet rays with a black light. Therefore, even when an illegal distributor illegally distributes a product integrated with the printed matter of the present invention (for example, when the product is illegally distributed after removing the two-dimensional code display unit from the printed matter), the illegal distribution is performed. The product identification information can be read with the naked eye by a simple operation of collecting the product and irradiating the printed matter integrated with the illegally distributed product with ultraviolet rays with black light. That is, by using the printed matter of the present invention, it is possible to investigate the cause of illegal distribution and to investigate the cause at an early stage. That is, in the printed matter of the present invention, the product identification information can be confirmed by a simpler operation as compared with the "operation of peeling off the exterior sheet" of the invention described in Patent Document 1 described above.

Further, the printed matter of the present invention has a configuration in which the product identification information is printed with invisible ink on one side of the base material so as to be superimposed on the product information display unit printed with visible ink. According to this configuration, it can also be used for a product container such as a transparent bottle.
Further, since the printed matter of the present invention can be created by superimposing the product identification information on the product information display unit printed with visible ink and printing the product identification information with invisible ink, the invention described in the above-mentioned Patent Document 1 " An ID symbol is printed on a sheet material formed of a transparent film, a masking print layer is printed on the ID symbol, and a basic print layer including a legal label of a product is printed on the masking print layer. It can be manufactured at a lower cost without spending more manpower than the configuration formed by.

Since the legally displayed information of a product is information necessary for selling the product, it is extremely unlikely that an unauthorized distributor will cut it, scrape it, or fill it with magic. In fact, looking at the trends of illegally distributed products so far, it is rare that the legally displayed information is cut off or deleted. Therefore, in the present invention, the product identification information is printed with invisible ink on top of the legally displayed information, which is unlikely to be cut off by an unauthorized distributor.

Further, it is desirable that the base material is a material for forming a storage container or a packaging container for the product.
As described above, according to the present invention, it is also applied to cosmetics, high-class shampoos, etc., in which product information and the like are printed directly on a product container (product storage container or packaging container) made of paper, synthetic resin, or the like. can. That is, the present invention can be used for general purposes as compared with the invention described in Patent Document 1 described above.

Further, it is desirable that the base material is a label formed in a sheet shape, an adhesive layer is formed on the other side, and a laminated layer is formed on one side thereof.
By configuring the label in this way, it is possible to provide a label on which the printed surface on which the product information or the like is printed is protected.

Further, the present invention is a printing method for printing various information on one side of a base material, and is required to be displayed on a product on one side of the base material by a first printing machine. By the step of printing the product information including the information with the visible ink and the second printing machine provided with the invisible ink, the area of one side of the base material on which the product information is printed does not overlap with the printed product information. On the other hand, at least, the two-dimensional code information shown by converting the information including the product identification information uniquely assigned to the product into a two-dimensional code is printed with visible ink, and the printed legal display is performed. It is characterized by having a step of printing the product identification information with the invisible ink on top of the information .
