Abstract

PROBLEM TO BE SOLVED: To improve the versatility of an information display part by previously forming a fluorescent base layer on the information display surface of an article and overlappingly printing an interception layer in accordance with a necessary information content by a user. SOLUTION: The band-like fluorescent base layer 2 including fluorescent material is formed on the surface (information display surface) of a postcard 1 as a paper piece. The fluorescent base layer 2 can be constituted by applying fluorescent on the whole surface of the postcard 1. The interception layer where many bar-like clearances crossing the fluorescent base layer 2 in the direction of width are formed is overlappingly printed on the fluorescent base layer 2. The interception layer is formed by black ink intercepting fluorescence. By forming the interception layer, the fluorescent base layer 2 is exposed from a non-intercepting surface generated by the bar-like clearances, and fluorescent bars are generated. Then, an information display part showing necessary information is formed by the fluorescent bars.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article having an information display surface on which an information display portion such as a barcode containing a fluorescent substance is formed.

[0002]

2. Description of the Related Art Items having an information display surface capable of displaying an information display portion such as a bar code include forms, postcards, membership cards, licenses, cards, wrapping paper, wrapping bags, labels, sticker stickers, etc. There is a piece of paper. In such a piece of paper, an information display section such as a bar code is provided for the purpose of address management, sales management, inventory management, member management, and theft prevention.
As the information display unit, a printed product such as a bar code containing a fluorescent substance is also used. This product selectively receives fluorescence generated by irradiated excitation light (ultraviolet light etc.) and displays information. Read. Various reading means have been proposed, as disclosed in Japanese Patent Laid-Open No. 3-214280.

As described above, in the structure in which the information display portion containing the fluorescent substance is printed on the surface, the fluorescence (radiation light) of a predetermined wavelength generated by the irradiation of the excitation light is optically processed. Therefore, the discrimination process is easier than the method of discriminating by the difference in reflectance between the print bar and the surface of the material, and the influence from natural light or the light of lighting equipment can be prevented. There is an advantage that accurate information can be read. Further, it can be formed in a nearly transparent state, and in this case, there is also an advantage that the information display section is inconspicuous.

[0004]

By the way, such an information display portion such as a barcode containing a fluorescent substance is
Due to the peculiarities of the ink material, it is not possible for the user to easily perform print formation. Therefore, it is not versatile and can be used only in a specific limited management system. It is an object of the present invention to improve the versatility of an information display unit such as a barcode containing such a fluorescent substance.

[0005]

According to the present invention, a fluorescent underlayer containing a fluorescent substance is formed on an information display surface by which a shielding layer is overprinted to form an information display portion for displaying required information. And an information display surface having the information display unit.

The article provided with the information display surface here means a form, a postcard, an envelope, a membership card, a license, a card, a wrapping paper, a packaging bag, a book, a label, a plastic piece, a sticker for sticking, and the like. There is one side. This paper piece means all the paper pieces that can be printed by the information display unit, regardless of the material, the number of sheets, and the shape. In addition, as the article provided with the other information display surface, equipments such as OA equipments, machines and tools capable of directly forming the information display portion can be cited. In short, all articles that can be formed with the information display unit are targeted.

In this structure, when the shield layer is overprinted on the fluorescent underlayer, only the portion not covered by the shield layer is exposed. For example, it is assumed that the fluorescent underlayer is formed in a band shape and a large number of bar-shaped gaps are formed across the shielding layer over the fluorescent underlayer in the width direction. As a result, when the shielding layer is printed on the fluorescent underlayer, the fluorescent underlayer is exposed from the bar-shaped gap, and the exposed surface causes a fluorescent barcode.

Then, the information display portion such as a bar code containing the fluorescent substance constituted by the non-shielding surface of the shielding layer, which is not printed, is irradiated with excitation light (ultraviolet light or the like) by the optical reading device to emit the fluorescent substance. Information is read by receiving the fluorescence emitted from the device.

By thus forming the fluorescent underlayer on the article in advance, the user may print a shielding layer made of black ink or the like similar to the conventional barcode. , No need for special fluorescent ink,
The versatility of fluorescent barcodes is improved. The present invention is not limited to the barcode, but may be any information display unit that is not covered with the shielding layer and can display information with the non-shielding surface.

It should be noted that the fluorescent bar code has an advantage that it can be formed substantially transparent and is inconspicuous, whereas it can be said that when the shielding layer is formed on the fluorescent bar code, the advantage cannot be achieved, but a simple bar code. Due to the formation, it is expected to be used as a simple forming means, which is different from the normal fluorescent bar code forming process.
