Description

The present invention relates to a packaging material a dot pattern obtained by encrypting information is printed, difficult dot patterns visually relates packaging materials that do not impair the printed image. In the present invention, an image has meaningful information such as characters, figures, and photographs.

Conventionally, encrypted information, such as a barcode, is printed on a packaging material body . The barcode has a large area and is printed while occupying a predetermined area of the packaging material .

In recent years, encrypted information has been printed on a packaging material body with a fine dot pattern. Since the fine dot pattern occupies a smaller area than the barcode, the following usage method is also employed. For example, if a fine dot pattern is printed in a dog image and a reader (scanner) is applied to the dog image, a voice “Inu” is produced or various explanations about the dog are produced by voice. The usage method is used.

  By the way, a fine dot pattern is printed with carbon black, read by a scanner having an infrared irradiation unit and an infrared reflected light reading unit, and the encrypted information is converted into other recognition means such as voice and outputted. Is. Therefore, if a dot pattern is printed with carbon black in a dog image, the dog image may be damaged.

  For this reason, when printing an image of a dog using cyan, magenta, yellow and carbon black, first print the dog image with cyan, magenta and yellow, and then print a dot pattern with carbon black in the dog image. In addition, a technique of completing a dog image is employed (Patent Document 1). However, this method has a limitation that it cannot be applied when printing an image using only carbon black. In addition, there is a limitation that it cannot be applied when an image is printed only with cyan, magenta, and yellow without using carbon black. That is, there is a grudge that this method cannot be applied to any printed matter.

Japanese Patent No. 4243644

An object of the present invention is to provide a packaging material capable of applying a dot pattern to an image of any color.

  In order to solve the above problems, the present invention forms a dot pattern with an infrared absorbing pigment exhibiting a predetermined color, and forms an image with an infrared transmitting pigment exhibiting substantially the same color as the predetermined color above or below the dot pattern. Formed.

That is, the present invention relates to a metal foil as a packaging material body, a white solid print surface applied to the surface of the metal foil, a dot pattern printed on the white solid print surface, and a print on the dot pattern surface. A character layer, a trademark, a photograph, or the like, and an image layer having meaningful information, and the dot pattern contains encrypted information, and an infrared irradiation unit and an infrared reflected light reading unit A packaging material in which the encrypted information is converted into voice, text or image recognition means and output through a scanner having the scanner, and the dot pattern is formed by an infrared absorbing pigment such as carbon black or phthalocyanine green. The image layer is printed in a predetermined color, and the image layer is substantially the same as the dot pattern by a coating pigment that easily transmits infrared rays by covering the pigment surface with a synthetic resin film. It relates a packaging material which dot patterns are printed, characterized in that is printed in color. The image layer and the dot pattern may be printed in reverse, and the dot pattern may be printed on the image layer surface.

The principle of the present invention will be described as follows. FIG. 1 is a schematic side view of a packaging material in which a dot pattern and an image are printed on the white solid print 5 side of a metal foil 1. The black square indicates each dot 2 constituting the dot pattern, and the white square indicates each halftone dot 3 constituting the image. FIG. 2 is a schematic side view showing a state in which the scanner 4 is applied to the image and the image is irradiated with infrared rays, and arrows indicate the infrared rays. Although the scanner 4 and the image layer are illustrated apart from each other, the scanner 4 may be in contact with the image layer. Since each halftone dot 3 is formed of a coating pigment that facilitates the transmission of infrared rays, the infrared rays irradiated to each halftone dot 3 are transmitted. Then, after passing through each halftone dot 3, the infrared rays irradiated to the dots 2 are absorbed because the dots 2 are formed of an infrared absorbing pigment. Infrared rays that have passed through each halftone dot 3 and have been irradiated to locations other than the dots 2 are reflected from the surface of the white solid print 5 , reflected again through each halftone dot 3, and this reflected infrared ray is read by the scanner 4. (Figure 3). As a result, the information encrypted by the dot pattern is recognized by the scanner 4 and converted into sound or the like and output. In the above example, each halftone dot 3 of the image is printed on the dot pattern. However, even if a dot pattern is printed on each halftone dot 3 of the image, the same principle is applied. The information encrypted by the pattern is recognized by the scanner 4 and converted into sound or the like and output.

  In the present invention, a pigment that easily transmits infrared rays is used as a pigment constituting each halftone dot 3, and a pigment that easily absorbs infrared rays as a pigment constituting each dot 2 is used. A feature of the present invention is that the color of each halftone dot 3 and the color of each dot 2 are formed in substantially the same color so that the dot pattern can be read regardless of the coloration. .

  As the pigment constituting the dots 2, conventionally known infrared absorbing pigments such as carbon black and phthalocyanine green are used. A plurality of infrared absorbing pigments are mixed and mixed so that the color of the dot 2 is the same as the color of the image. On the other hand, the color of each halftone dot 3 is mixed using a coating pigment developed by the present inventor that easily transmits infrared rays (Japanese Patent No. 4731108 and Japanese Patent No. 3771922). This coated pigment is obtained by coating the pigment surface with a synthetic resin film, and the pigment itself is easy to absorb infrared rays, but by coating with a synthetic resin film, infrared rays are easily transmitted. .

In the present invention, an infrared absorbing pigment is mixed as a pigment for printing a dot pattern, while a coating pigment that easily transmits infrared rays is mixed as a pigment for printing an image so that the two have substantially the same color. Mix colors. And an image is printed on a dot pattern, or a dot pattern is printed on an image to make a packaging material . Accordingly, since the image and the dot pattern have substantially the same color, the dot pattern can be formed without damaging the image.

It is a typical side view of the packaging material which concerns on an example of this invention with which the dot pattern and the image were printed. It is the typical side view which showed the state which applied the scanner to the image of the packaging material of FIG. 1, and has irradiated the infrared rays. It is the typical side view which showed the state which applied the scanner to the image of the packaging material of FIG. 1, and reflected the infrared rays.

A metal foil is used as the packaging material body used in the present invention. Since the printing base of the metal foil has a metallic luster , white solid printing is performed before printing a dot pattern or an image. This is because if the printing base has a metallic luster, the infrared light transmitted through the image is not reflected well, and the reflected light is difficult to read by the scanner 4. Moreover, it is preferable to use aluminum foil as metal foil. This is because aluminum foil is suitably used as a packaging material, and is particularly commonly used in press-through packs, which are tablet containers, and is versatile.

  The dot pattern is printed using an infrared absorbing pigment such as carbon black or phthalocyanine green. In order to set the dot pattern to a predetermined color, infrared absorbing pigments of various colors may be mixed and mixed. For example, carbon black, phthalocyanine green, disazo yellow, phthalocyanine blue, condensed azo red, insoluble azo red, disazo orange or dioxazine violet may be mixed and mixed. Although the dot pattern is basically formed of an infrared absorbing pigment, a slight amount of an infrared reflecting pigment such as titanium dioxide may be mixed. This is because the reflection intensity of infrared rays is small if it is a slight amount, and misidentification is unlikely to occur during reading by the scanner 4.

The image is formed of a coated pigment that easily transmits infrared rays by coating the pigment surface with a synthetic resin film. Details of the coated pigment are specifically described in Japanese Patent No. 4731108 and Japanese Patent No. 3771922. In order to obtain a black pigment with a coating pigment, it is preferable to use perylene black represented by the following structural formula (I) without using carbon black (Japanese Patent No. 3771922). This is because this perylene black is black but has excellent infrared transparency.

  In addition to the perylene black, other coating pigments are mixed and mixed to give a predetermined color to the image. For example, a coated pigment in which phthalocyanine green, disazo yellow, titanium dioxide, condensed azo red, insoluble azo red, phthalocyanine blue, dioxane violet, or disazo orange is coated with a synthetic resin film is used. In order to obtain the coated pigment, for example, a vinyl acetate-vinyl chloride copolymer may be heated and melted on a roll disperser, and the pigment may be added and dispersed therein (Japanese Patent No. 4731108 and Japanese Patent No. 3771922). .

The packaging material according to the present invention is obtained by the following method. First, a metal foil is prepared. The surface to be printed is subjected to white solid processing. A dot pattern is printed on the white solid processing (white solid printing 5) surface using a predetermined color ink containing an infrared absorbing pigment. Next, if an image is printed on the dot pattern surface using ink of substantially the same color including the coating pigment, the packaging material according to the present invention can be obtained. In addition, after printing an image using a predetermined color ink containing a coating pigment on the white solid printing surface, a dot pattern is formed on the image surface using an ink of substantially the same color containing an infrared absorbing pigment. Even if it prints, the packaging material which concerns on this invention can be obtained.

  On the packaging material according to the present invention, an image such as a photograph or a description of the stored contents is printed. If a dot pattern is printed in this image, a description of the contents is converted into sound by applying a scanner to the image, and the explanation about the contents is read by a person who cannot read characters Free people can recognize. In particular, press-through packs containing tablets such as drugs are packaging materials made of aluminum foil, but if a dot pattern is printed in the image of characters, trademarks, etc. printed on the surface of this aluminum foil, the image By applying the scanner to the device, information such as the type, efficacy, and expiration date of the drug can be recognized by voice. Therefore, even an elderly person who easily takes a medicine can recognize the medicine information by voice, which is convenient.
