Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for creating a form on which barcode symbols are printed.

In recent years, various methods have been developed for logistics management systems.
Among these systems, there are management systems that use barcode symbols as symbols, such as point-of-sales (POS) systems.

) management, warehouse management, medical management, production management, shipping management,
It is widely used for other management purposes.

Note that the above-mentioned barcode symbol is usually a numerical code patterned by a combination of bars depending on line thickness, spacing, color classification, etc., and is used as a managed code.

Currently, this barcode symbol is usually printed using a barcode printer.
In this case, there is a drawback that there is no adaptability to variable information.

In other words, to explain the current method in more detail, for example, each digit of the barcode symbol is manually set for input information such as price, product number, size, etc., and then the letterpress printing method and transfer printing method area are A barcode symbol is printed on plain paper such as a price tag using mechanical printing means such as a type ribbon printing method, and a form with the barcode symbol printed thereon is manufactured.

Therefore, in this manufacturing method, the printer is composed of a town character part containing the required number of digits, and the printing part for one digit is formed from 10 characters from 0 to 9, and the same number of digits are formed. A printing section consisting of the configuration is horizontally arranged for the required number of digits, and when a function code (start code, stop code, etc.) is added, it usually consists of 20 to 26 digits.

However, in this printing method, although it is suitable for producing a form in which multiple barcode symbols are printed for each piece of input information, barcode symbols are printed one sheet at a time for each piece of input information. It is extremely difficult to produce such forms.

In general, the input information varies widely depending on the type of product, etc., and therefore, the input information is always variable information, and a form with a barcode symbol printed on it corresponding to this variable information is printed each time. It is necessary to manufacture each product separately.

However, in the above-mentioned manufacturing method that uses mechanical printing means, it is difficult to produce a form with a barcode symbol printed on it that corresponds to each piece of input information, especially in the case of random information. Barcode raised characters (
In terms of processing power, it is nearly impossible to manually select and set the ``Katsuji'' each time, and it takes a huge amount of time.Also, there is a risk of operational errors in the settings, and furthermore, Furthermore, it is extremely difficult to confirm the information until it is printed.

In addition, in the above printing method, the printed barcode symbol is expressed using ink or ribbon ink as an ink substitute, so the barcode symbol can easily fall off due to extremely weak frictional force, etc. In addition, it is very easy to get dirty, and there are many problems in terms of quality, precision, printing density, etc.

For example, when a general consumer purchases a product at a store, a store clerk inputs the barcode information into the POS terminal's reader (
When using a barcode symbol using the above-mentioned ink, etc., the ink may fall off due to physical friction.
Contamination and the like occur due to drying of the ink, resulting in reading errors and a disadvantage that the control function is not fulfilled.

As a result of various studies to improve the above-mentioned drawbacks, the present inventor has found that
We have discovered a printing method for barcode symbols that has a high degree of freedom in handling variable input information.Furthermore, the printed barcode symbols have extremely excellent abrasion resistance, stain resistance, etc., and are of high quality. The present invention was completed by discovering the barcode form.

That is, the gist of the present invention is a method for creating a barcode form, which is characterized in that a barcode symbol is exposed on a photosensitive layer of a photosensitive material using a cathode ray tube, and then developed using a developing method suitable for the photosensitive material. That is.

The above invention will be explained in more detail below.

FIG. 1 shows a barcode form obtained by the present invention,
The barcode symbol 3 is printed on a photosensitive material 1 using an exposure and development method in accordance with input information 2 such as the price, product number, size, etc. of the product.

Therefore, in the above-mentioned present invention, the photosensitive material is
Any material can be used as long as it has a photosensitive layer on the base layer and can perform optical printing, such as silver salt photosensitive materials, diazo or azide photosensitive materials, photosensitive dye coloring materials, Others can be used.

Furthermore, in the present invention, electrophotographic light-sensitive materials can also be used satisfactorily as the light-sensitive material of the present invention due to their basic functions.

To further explain the above-mentioned photosensitive materials, for example, various papers such as ordinary high-quality paper, coated paper, and paperboard, polyester, polycarbonate, polyethylene, polystyrene,
The base material is a film or sheet of various resins such as polyvinyl chloride, polyvinylidene chloride, polypropylene, polyamide, polyvinyl alcohol, acetate, and other resins, metal foil, metal plate, etc., and on this base material,
Recording materials in which a photosensitive layer is formed by coating a photosensitive composition such as a silver salt photosensitive composition, a diazo or azide photosensitive composition, a dye coloring type photosensitive composition, or others can be used. .

Further, as the above-mentioned electrophotographic photosensitive material, a photosensitive layer is formed by coating the above-mentioned base material with a composition containing, for example, zinc oxide, cadmium sulfide, or polyvinyl rubazole resin. Recording materials etc. can be used.

Specifically, various printing lines, printing lines for phototypesetting, silver salt-based photosensitive materials such as photographic film or photoengraving film, various types of diazo paper (wet or dry development), and various zinc oxide papers (
wet or dry development), dry silver (manufactured by Sumitomo 3M,
dry (thermal) development, silver salt type), dry chrome (manufactured by Dai Nippon Printing K.K., dry (light exposure) type development, photochromic system), Dilux (manufactured by DuPont, dry (light exposure) type development, Chromalin (manufactured by DuPont, one-way toner development, photoadhesive), Culver Film (manufactured by Culver, heat development,
Materials such as cyazo-based), Polaroid film (manufactured by Polaroid, wet development, silver salt-based), and others can be used.

In the present invention, when forming the photosensitive layer on the base material, it is sufficient to form it at least on the part where the barcode symbol is printed, and it may be formed on the entire other surface. In this case, it may be formed in advance, or it may be formed in spots immediately before printing the barcode symbol.

Furthermore, in the present invention, the developing method for these recording materials may be either a wet type or a dry type.

Next, in the above-mentioned present invention, a method of printing a barcode symbol on a photosensitive material using an exposure and development method and thereby directly obtaining a barcode form will be explained. Any method may be used as long as the barcode symbol can be printed by exposing and developing the photosensitive layer of the material, but in the present invention, a cathode ray tube (Ca

The development method is the most desirable.

To explain this method in detail by giving an example, as shown in the block diagram of Fig. 2, barcode information is transferred to an LSI.
(Large Scale Integrated), etc., to save it as a character pattern, and then input variable information such as the product price, product number, etc. using a keyboard, paper tape, magnetic tape, etc. Then, according to this variable input information, the input information string is changed to the character/pattern memory from the character/pattern memory.
It is converted into a video signal by a generator and displayed on a CRT recording tube. With this, barcodes and symbol patterns are exposed on the photosensitive layer of the photosensitive material. After that, it is developed using a development method depending on the photosensitive material to make it photosensitive. It is possible to directly obtain a barcode form by printing each barcode symbol according to the input information on the material.

Alternatively, in the present invention, as another method of printing a barcode symbol on a photosensitive material using an exposure and development method to obtain a barcode form, for example, as shown in FIG.
Multiple mask materials with numbers up to 9 converted into barcode symbols are arranged horizontally according to the desired number of digits, and then barcodes are generated from each mask material according to variable information such as product price, product number, etc. The symbol is picked up, thereby forming a pattern of barcode symbols according to the variable information, and then this pattern of barcode symbols is optically exposed on the photosensitive layer surface of the photosensitive material, and then exposed to light in the same manner as above. It is possible to directly obtain a barcode form by developing the photosensitive material using a developing method suitable for the photosensitive material and printing each barcode symbol corresponding to the variable information on the photosensitive material.

In the present invention, there are various modifications to the above-mentioned exposure and development method, and the present invention may use any method as long as it can print a barcode symbol by exposing and developing a photosensitive material.
Needless to say, the present invention is not limited to the above two examples.

Therefore, in the present invention, the method for inputting the barcode information of the above-mentioned barcode form is based on the premise that it is directly connected to a computer, and the outputted barcode information is input and aggregated into the computer using a terminal. be done.

That is, the barcode printing method of the present invention can function not only as an independent mechanism for printing barcode symbols, but also as a part of a computer system, and the barcode printing information created by the method of the present invention can be used as an independent mechanism for printing barcode symbols. is the reader (
What is input and printed through a POS terminal (POS terminal) can be used as input information for printing barcode symbols again, and has a turnaround function.

As is clear from the above description, the method of the present invention consists of a barcode form in which barcode symbols are printed on a photosensitive material using an exposure and development method.

Therefore, according to the present invention, for example, every day, every hour,
Alternatively, it is possible to directly and immediately obtain a barcode form in which barcode symbols corresponding to variable input information that vary depending on the target article or the like are directly and immediately printed.

Further, according to the present invention, barcode forms are manufactured by an optical method using a photosensitive material, unlike the method of obtaining barcode forms by conventional printing methods, etc., so that the barcode forms obtained are The barcode symbol has excellent wear resistance, stain resistance, etc., and extremely high quality, accuracy, and information density.

In particular, in the present invention, whereas conventional barcode printers are limited to processing only semi-fixed information, the method of the present invention is capable of processing not only fixed information but also variable information (high-mix, low-volume information). ), its greatest feature is that it has functionality.

Further, in the present invention, when printing barcode information on a printing target medium, it is possible to arbitrarily select the barcode information,
Information can be written only on the necessary media, and there are no problems with ink stains or drying, and the optical recording (plateless) allows for high-density printing of barcode information. It is something.

Therefore, the barcode form obtained by the method of the present invention can be applied to, for example, store sales management, warehouse management, medical management, production management, shipping management, and various other management systems. For example, price tags, labels,
Continuous slips, sheet slips, OCR forms, MICR forms, coupon tickets, menus, order cards, estimates, credit cards, commuter passes, boarding passes, boarding passes, airline tickets, admission tickets, tickets,

Application form, exam paper, identification card, pay slip, savings passbook,
It can be used for a wide range of purposes, such as various packaging bags, (interior and exterior materials) envelopes, and cardboard boxes.

Therefore, the barcode form obtained by the method of the present invention can be applied to an article as it is or applied to the article by tack processing, etc., and therefore can be used for all kinds of articles. It is.

In addition, in the present invention, various processing processes such as tack processing, perforation processing, punching processing, etc. can be arbitrarily applied to the barcode form depending on the purpose and use. This can be done by a known method, and may be processed when recording the barcode symbol, or may be processed after the barcode symbol is recorded.
