When the light from the initial print information x overlaps with the reflected light or the fluorescent light from the print information y formed on the correction label a, thereby causing erroneous reading and preventing accurate information reading. There is a problem that An object of the present invention is to solve such a problem.

[0007]

SUMMARY OF THE INVENTION The present invention is applied to a print showing information readable by an optical reader, and prints information readable on an uppermost surface by the optical reader. In addition to the printing surface, a black layer is provided on the back or front surface of the base material layer, and further, on the lowermost surface, an adhesive layer for bonding on the adhered surface is provided. .

In such a configuration, infrared light emitted from the print and transmitted therethrough is absorbed by the black layer and cut off, thereby preventing erroneous reading of the optical reader by the corrected first print information. . In particular, when a material containing carbon is used as the black layer, it exhibits a low transmittance for light of all wavelengths, and is particularly effective.

On the other hand, in such a configuration, characters on the surface covered with the label on the adhered surface cannot be seen. Therefore,
Instead of the above-mentioned black layer, a configuration is proposed in which an infrared absorber is mixed in at least one of layers such as a base material layer, a receiving layer, and an adhesive layer.

In this configuration, the infrared ray emitted from the print and transmitted therethrough is absorbed and blocked by the infrared absorbent. In addition, each layer of the modified label
When a visually transparent material is used, the characters on the surface covered with the label on the adhered surface become visible. Here, visually transparent means that character information can be visually read through a layer, and there are transparent and translucent. In addition, even when the base material layer and the receiving layer do not use a visually transparent material, erroneous reading by the first print information is prevented.

Further, instead of mixing the infrared absorbing agent, an infrared absorbing layer may be provided on the back surface or the front surface of the base layer. The infrared absorbing layer may be formed by mixing an infrared absorbing agent with a synthetic resin agent. Even in this case, similarly to the above, it does not prevent the use of a material having no visual transparency.

[0012]

1 and 2 show an information correction label 1 according to the present invention. Base layer 2 of this information correction label 1
A black layer 8 printed with black ink is formed on the lower surface, and an adhesive layer 3 is formed on the lower surface of the black layer 8, and a release paper 4 is bonded to the adhesive layer 3. As the base material layer 2, a resin base material made of white polyethylene can be used. For the black layer 8, black ink (black ink) containing carbon may be used.

A receiving layer 5 is formed on the upper surface of the base material layer 2, and print information y which can be read by an optical reading device composed of a bar code is formed on the receiving layer 5 by thermal,
The information display surface is printed by a printing means such as an ink jet. When printing information y such as a bar code is printed, the receiving layer 5 makes the printing information y easy to ride and prevents peeling.

The material of the receiving layer 5 includes printing information y
Various types are selected depending on the type of the ink.

As shown in FIGS. 1 and 2, the information correction label 1 having this configuration is on a mount 12 such as a form, a delivery slip, a product bag, a home delivery, a postcard, etc., and its character information is described. When it is necessary to correct the initial print information x which is printed on the mount 12 in advance and is readable by the optical reader, the corrected print information y is printed on the receiving layer 5 in advance. Later, after the release paper 4 is removed, it is pasted on the initial print information x. Then, the print information y corrected by the optical reader is obtained.
As genuine information, delivery sorting, inventory management,
It will be used for sales management.

In such a configuration, the infrared light generated from the first print information is absorbed by the black layer 8 and is completely blocked. That is, when the initial print information x is printed using fluorescent ink, the black layer 8 absorbs infrared light (excitation light), which is radiation light from the optical reader, and the excitation light The generated fluorescence from the first print information x is absorbed by the black layer 8. Also. Initial print information x
Is printed with normal ink and reads the reflected infrared light radiated from the optical reader.
By absorbing the radiated light and the reflected light, the influence can be removed.

For this reason, the print information y is read by the optical reading device.
When reading is performed, it is possible to perform appropriate information reading without being adversely affected by infrared light or fluorescence from the first print information x.

FIG. 5A shows an information correction label 1 according to the configuration of FIG. 1 in which the initial print information x is printed using fluorescent ink, and a black ink (black ink) containing carbon is used as the black layer 8. Shows a spectral curve when the first print information x is covered. FIG. 5B is an information correction label 1 according to the configuration of FIG. 1 in which the first print information x is printed using fluorescent ink and black ink (black ink) containing no carbon is used as the black layer 8. 7 shows a spectral curve when the first print information x is covered. On the other hand, FIG. 6 shows a spectral curve of the same configuration, in which only the black layer 8 is removed. As apparent from a comparison between FIGS. 5A, 5B and 6, the structure using the black layer 8 containing carbon shown in FIG. Rate. On the other hand, the structure using the black layer 8 containing no carbon shown in FIG. 5B has a high transmittance from 700 nm or more, and thus the wavelength of the emitted light of the optical reader is set to a low wavelength. Proved to be effective. In addition, it was shown that, in the configuration without the black layer 8, the transmittance was high as a whole, and erroneous reading due to the initial print information x was likely to occur.

In such a configuration, the receiving layer 5 is made of a polyester resin and a white pigment (product name: CV
L-PTN709 white) and silica may be mixed and used as an optical reflection layer. As a result, the light x emitted from the optical reader is scattered and reflected by the white particles of the optical reflection layer 5, and the transmittance for light of a predetermined wavelength readable by the optical reader is reduced, thereby producing a reflection effect. For this reason, the transmittance of infrared rays of the information correction label 1 can be reduced, and the influence of the first print information x can be further reduced.

When other necessary character information previously printed or handwritten is present on the surface of the backing paper 12, the information correction label 1 is stuck on the character information intentionally or unintentionally. May be. In this case, if the information correction label 1 becomes opaque due to the black layer 8, the character information becomes illegible, which may cause trouble.

Therefore, in this case, as shown in FIG. 3, a material having visual transparency is used for the base layer 2 and the receiving layer 5, and the base layer 2 is replaced with the black layer 8. 2. When an infrared absorbing agent is mixed into the adhesive layer 3 or the receiving layer 5, characters on the surface covered with the label on the adhered surface become visible. Here, visually transparent means that character information can be visually read through a layer and is transparent and translucent. As a result, visible light can be transmitted through the information correction label 1, and characters on the surface covered with the label 1 on the adhered surface can be viewed.

As the infrared absorber, generally, an atraquinone compound, an aminium compound, a polyethylene compound, a diimonium compound, a cyanine compound or the like can be used.

On the other hand, instead of mixing the infrared absorbing agent, an infrared absorbing layer 10 may be provided on the back surface or the front surface of the base layer 2 as shown in FIG. The infrared absorbing layer 10 may be formed by mixing an infrared absorbing agent with a synthetic resin agent.

In this embodiment, an infrared absorbing layer 10 is provided between the base material layer 2 and the receiving layer 5. In addition, the base material layer 2
And the adhesive layer 3 may be provided.

As described above, when the infrared absorbing layer 10 is used, the material conditions are relaxed as compared with the structure in which the infrared absorbing agent is mixed in any of the layers, and the selection of the absorbing agent is made. The range expands. When the material is covered and mixed into the base material layer 2, the adhesive layer 3, and the receiving layer 5, the material must be selected in consideration of the characteristics of each material. This is because it is necessary to select a material that does not interfere.

[0026]

According to the present invention, as described above, a receiving layer is formed on a base material layer, and the upper surface of the receiving layer is used as a printing surface on which information readable by an optical reader is printed.
In the configuration in which an adhesive layer for bonding on the adhered surface is provided on the lowermost surface, and a black layer is provided on the back surface or the front surface of the base material layer, light transmitted through the label is transmitted to the black layer. In the case where the information correction label is attached to the first print information x on the surface to be attached, erroneous reading by the optical reading device due to the influence of the first print information x is prevented and corrected. It is possible to read the print information y properly.

In place of the above-mentioned black layer, an infrared absorbing agent is mixed in any one of the base material layer, the receiving layer and the adhesive layer, or the infrared absorbing layer is provided on the back or front surface of the base material layer. Even with the arrangement, misreading by the optical reader due to the influence of the first print information x is prevented. In this case, by using a visually transparent material for the base layer and the receiving layer, the influence of the initial print information x can be prevented, and the characters on the surface covered with the label on the adhered surface can be prevented. Becomes visible.
