Abstract

PURPOSE:To read out information by an optical reader having an optional reading waveform by patterning a specific specular gloss layer formed on one face of an information medium having no or less specular gloss as a shape corresponding to information and optically reading out a difference in mirror reflection factor. CONSTITUTION:A specular gloss layer containing pearl pigment and formed on one face of the information medium having no or less specular gloss is practically superposed to a color layer and patterned to a shape corresponding to information or the specular gloss layer containing the pearl pigment and the coloring agent is patherned to the shape corresponding to the information. Then, a difference between the reflection factors of the specular gloss layer and the information medium is optically read out. Consequently, information is read out by any optical reader such as a bar code reader and an OCR using the light of specific wavelength from visible to a near infrared area without selecting reading wavelength.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention has pearlescent luster of any hue and can be applied to any conventionally used /<- coat reader, O
It relates to recorded materials for verification that can be read with an optical reading device such as CR.

(Conventional technology) Conventionally, logistics management, product management, materials management, inventory management, PO
In management systems such as the S system, information is input using barcodes in order to eliminate the complexity of key personnel and bookkeeping. /<- Code marking includes source marking, which creates large quantities of the same type of barcode using offset printing, gravure printing, flexographic printing, letterpress printing, screen printing, etc., and source marking, which creates large quantities of the same type of barcode by printing such as offset printing, gravure printing, flexo printing, letterpress printing, and screen printing, and thermal transfer, thermal coloring, and
There are in-store markings, in-house markings, or on-demand markings that create a limited amount of individual barcodes using printers such as wire tod type barcode printers, inkjet printers, and racer printers, and recorded barcode printing or printing. The reflection intensity of an object can be measured using a 632.8 nm He-Ne laser, a 660 nm light emitting diode, a 670 nm visible light semiconductor laser, a 690 nm light emitting diode,
By measuring using a light source such as a 780 nm semiconductor laser or a 940 nm infrared light emitting diode, code information is easily input and the data is processed by a computer.

The ink used for these barcodes is brown, dark blue, or brown using carbon black, due to design issues. 600 to 700 nm when detecting using dark chromatic ink such as dark green or a visible light source of 600 to 700 nm.
Inks using pigments from fruits, vegetables, and edge threads that absorb in the area are also used. However, it had the disadvantage of being limited to cool colors such as brown, blue, and green, which may have been due to color constraints in the design.

In addition, ink using metal powder is also used for source marking, and since barcodes with metallic luster such as gold and silver have high specular reflectance, the reflection intensity of the above-mentioned specific light is measured. Can the detection device read the same as a black barcode?
The drawback was that it was limited to metallic colors such as silver.

(Problems to be Solved by the Invention) In view of this problem, the present invention focuses on the fact that it can be read using a material that causes specular reflection or a conventional detection device that measures the reflection intensity of light, and is limited to dark and cold colors. To provide a record for verification that has any hue including bright colors and warm colors and can be read by conventionally used optical reading devices such as barcode readers and OCR with any reading wavelength. It is something.

[Structure of the invention]

(Means for Solving the Problems) That is, the present invention provides a method in which a specular gloss layer containing a pearl pigment and a colored layer are substantially superimposed on at least one surface of an information medium that has no or little specular gloss to form a shape according to information. A recorded material for verification is characterized by patterning or patterning a specular glossy layer containing a pearl pigment and a coloring agent into a shape according to information, and optically reading the difference in reflectance between the specular glossy layer and the information medium. In addition, by sequentially laminating a colored layer and a specular gloss layer containing a pearl pigment, or by sequentially laminating a specular gloss layer containing a pearl pigment and a transparent colored layer containing a highly transparent coloring material, The present invention relates to the above recorded matter for verification, characterized in that it is patterned into a shape.

The above-mentioned verification record is scanned by an optical reading device such as a normal barcode reader or OCR, which reads information by measuring the reflected intensity of visible or near-infrared light.
It can be read in the same way as black letters, numbers, or symbols, and is effective for verifying product lot numbers and product numbers given to various products for product management purposes.

In the present invention, the colored layer is overlapped with the specular gloss layer, but there may be a colored layer in a part other than the specular gloss layer, and the specular gloss layer and the colored layer are overlapped, and the other colored layer is overlapped with the specular gloss layer. It may also be formed on a portion including the top. Note that a coloring agent may be used in combination with the specular gloss layer to form a layer equal to the specular gloss layer.

The pearl pigment of the present invention is a pigment that exhibits an elegant shine called pearl luster due to multiple reflections of light, and is a pigment that exhibits an elegant shine called pearl luster due to multiple reflections of light. Mention may be made of synthetic pearlescent pigments. The pigment is made of a transparent substance with a high refractive index,

In addition to information regarding the same shape, information regarding color can be added. Specifically, because colors can be easily identified visually,
Information such as season, production line, person in charge, region, size, manufacturer, etc. can be added as colors, which is convenient for sorting. Also, color constraints on design are reduced.

Furthermore, a pattern shaped according to the information can be read by any optical reading device such as a barcode reader or OCR that uses light of a specific wavelength in the visible to near-infrared region as a light source, regardless of the reading wavelength. Therefore, in the same way that black patterns have traditionally been used to identify objects over a wide range of wavelengths, it is possible to identify them over a wide range of wavelengths.
