Abstract

In this printed code in which an identifier that can be read using a reader is printed, a label that is tiny enough that the presence thereof cannot be recognized by the reader is positioned within the printed code. This makes it possible for a user (e.g., a consumer, or a manufacturer or distributor of a genuine commodity) to identify that a commodity corresponding to a printed article on which the printed code is printed is a genuine commodity, and to identify that a commodity corresponding to a printed article on which is printed a printed code lacking the tiny label is an illicit commodity, while it is possible for the printed code to be read using a reader.

Description

A code printed with an identification code that can be read by a reader

The present invention relates to a code printed with an identification code readable by a reader.

In recent years, the trade in illegal goods (counterfeit goods, counterfeit goods) that infringe upon trademarks or copyrights has grown steadily. If illegal products such as medical supplies, auto parts, toys, food, cosmetic brands, and electrical products are circulated, there is a risk that the health or safety of consumers will be completely exposed. However, it is difficult to take effective countermeasures against the trade of such illegal goods. [Prior technical literature] [Patent Document]

(The problem that the invention wants to solve)

The problem to be solved by the present invention is to identify genuine goods and illegal goods in the circulation process, so as to prevent the transaction of illegal goods. (Technical means to solve problems)

The code of the present invention is printed with an identification code that can be read by a reader, and a mark so minute that the reader cannot recognize its presence is disposed in the code. Thereby, the code can be read by a reader, and users (such as consumers, manufacturers of genuine goods, and distributors) can identify the goods corresponding to the printed matter printed with the code as genuine goods, and Products corresponding to printed materials printed with codes without micro-marks are identified as illegal products.

An embodiment in which a code (code) with an identification code readable by a reader is printed will be described in detail below with reference to the drawings.

FIG. 1 shows a code in which an identification code readable by a reader (also referred to as a "scanner") is printed, and a code in which a microscopic mark (hereinafter referred to as "Printing code")1. Next, FIG. 1 shows a two-dimensional code 10 as an example of the printed code 1 . Taking QR code 10 (the same applies to QR codes 30, 40, and 50 described below), the following are listed: QR code (registered trademark), PDF417 (including Micro PDF417, Compact PDF417, etc.), DataMatrix (registered trademark), MaxiCode, AztecCode, Code49, EAN/UPC composite code (Composite), GS1DataBar (RSS) composite code, etc. The QR code system includes: Model 1, Model 2, micro QR code, rMQR code, SQRC (registered trademark), Frame QR (registered trademark), etc. In the following description, the case where the QR code 10 (the same applies to the QR codes 30, 40, and 50 described later) is the model 2 of the QR code is not limited to this case.

QR code 10 (the same applies to codes 20, 30, 40, and 50 mentioned below) is printed on paper (including corrugated paper, sticky paper (sticker) on one side, etc.), plastic (including plastic film, on one side) Attached to printed materials made of sticky plastic film (stickers, etc.), vinyl (vinyl), or cloth (including non-woven fabrics, etc.). The printed matter constitutes, for example, the product itself, the packaging of the product, or accessories attached to the product (such as instructions or product labels (including tags)), etc., and is circulated together with the corresponding products. Among them, printed materials constitute advertisements (including leaflets, etc.) or price lists for products, and may be distributed separately from the corresponding products.

The QR code 10 is composed of a central data area (symbol) S and a surrounding quiet zone Q. The QR code 10 is a type of identification code in which plural symbol cells (cells) constituting an identification code are two-dimensionally arranged on the symbol S and represent information represented by characters. QR code 10 is a code that converts the information shown in text into a two-dimensional code according to certain rules. The QR code 10 can be input and output by a reader (such as a QR code reader) as easily readable digital information. Among them, the two-dimensional code 10 may include a finder pattern, an alignment pattern, or the like that constitutes the identification code placed on the symbol.

In addition, in the two-dimensional code 10, a mark is arranged in at least one symbol element (the symbol A in FIG. 1 represents one symbol element) among the plural symbol elements of the two-dimensional code 10 (as shown in FIG. 2(A)). )). The logo is, for example, composed of at least one of characters (including language characters, numbers, symbols, etc.) or patterns. The language character system includes characters representing various languages, and means, for example, Japanese (including hiragana, katakana, and kanji), English (including letters), Chinese, Korean (Korean), French, German, Spanish, Text in Russian, Arabic and other languages. In addition, for example, the mark may be composed of any one of characters and images, or a combination thereof. Here, micro characters as micro marks are also called micro characters.

In addition, if there is a search pattern arranged in a symbol (symbol B in Fig. 1 indicates one search pattern), there may be a case where the mark is arranged in part or all of the search pattern that constitutes the identification code ( The diagram is shown in Figure 2 (B), (C)). In addition, if there is an alignment pattern (symbol C in FIG. 1 indicates an alignment pattern), there may be a case where the mark is arranged in part or all of the alignment pattern that constitutes the identification code (shown in FIG. 3(A) ), (B)). That is, the mark may be arranged only in the imaging pattern of the QR code 10, or the mark may be arranged only in the alignment pattern. In addition, the logo can also be arranged only in the imaging pattern and the alignment pattern of the QR code 10, or the logo can be arranged in the imaging pattern (or alignment pattern) and the symbol element.

2(A)~(C) show partial enlarged views of the two-dimensional code 10. FIG. 2(A) is an enlarged view of an example of part A of the two-dimensional code 10 shown in FIG. 1 . On the other hand, FIG. 2(B) is an enlarged view of the first example of part B of the two-dimensional code 10 shown in FIG. 1 . FIG. 2(C) is an enlarged view of the second example of part B of the two-dimensional code 10 shown in FIG. 1 . Next, FIGS. 2(A) to 2(C) are examples of arranging characters as logos in the two-dimensional code 10. In FIGS. 2(A) to 2(C) , for convenience, the size of the characters displayed relative to the size of parts A and B is changed.

As shown in part A of Figure 2(A), the QR code 10 is attached to a part of the symbol element, and the letter "R" as an example of a character is used as a mark, and the color (hue, chroma and lightness) of the symbol element is used as a mark. ) different colors (for example, if it is a black symbol element, the text will be white or a color close to this, if it is a white symbol element, the text will be black, gray, or colored) for configuration. Colors close to white include colors. The resolution of a QR code reader is not always better. The resolution that can be read by a general-purpose machine (such as a smartphone) is at most about 0.25 [mm]. Therefore, it is more appropriate to set the character size to 0.25 [mm] or less. Text sizes below 0.25[mm] include 0.7[pt], 0.6[pt], etc.

Next, if the user uses a magnifying glass to read the text within the symbol element (for example, white text within the black symbol element), if the text size is 0.25 [mm], it is more appropriate to use a symbol element with a size of 0.25 [mm] or more. When arranging text, if the text size is 0.18[mm], it is more suitable to place text on symbol elements with a size of 0.18[mm] or more. In addition, if the text size is larger than the size of one symbol element, the text can also be arranged across multiple adjacent symbol elements. For example, if the character size is 0.25 [mm] and the size of one symbol element is 0.17 [mm], white characters are arranged across four adjacent 2×2 black symbol elements.

Here, the text may be printed using the trade name (or its initials) of the product corresponding to the printed matter, or the name of the manufacturing company (or its initials) of the product.

As shown in part B of FIG. 2(B) , the QR code 10 is included in a part of the search pattern, and a mark "!(^^)!" as an example of a character is used as a mark, in a color different from that of the search pattern. Color (for example, if it is placed in the black part of the symbol, the text will be white or a color close to it; if it is placed in the white part of the symbol, the text will be black, gray, or colored). Colors close to white include colors. As mentioned above, the appropriate character size is 0.25 [mm] or less.

As shown in part B of FIG. 2(C), in the QR code 10, the symbols "circle mark" and "umbrella mark" as examples of characters are included in a part of the search pattern, and are related to the search pattern. Arrange colors that are different from the color of the style (for example, if it is placed in the black part of the symbol, the text will be white or a color close to it, if it is placed in the white part of the symbol, the text will be black, gray, or colored). Colors close to white include colors. As mentioned above, the appropriate character size is 0.25 [mm] or less.

3(A) and (B) are partial enlarged views of the two-dimensional code 10. FIG. 3(A) is an enlarged view of the first example of part C of the two-dimensional code 10 shown in FIG. 1 . FIG. 3(B) is an enlarged view of the second example of part C of the two-dimensional code 10 shown in FIG. 1 . Next, FIG. 3(A) is an example in which characters as logos are arranged in the two-dimensional code 10, and FIG. 3(B) is an example in which a pattern as a logo is arranged in the two-dimensional code 10. In FIGS. 3(A) and 3(B) , the size of the mark displayed relative to the size of the part C is changed for convenience.

As shown in part C of FIG. 3(A) , in the QR code 10, the Chinese character "rose" as an example of a character is used as a mark within the alignment pattern, in a color different from the color of the alignment pattern (for example, If it is placed in the black part of the alignment pattern, the text will be white or a color close to this. If it is placed in the white part of the alignment pattern, the text will be black, gray, or colored). Colors close to white include colors. As mentioned above, the appropriate character size is 0.25 [mm] or less.

As shown in part C of FIG. 3(B) , in the QR code 10 , a pattern (pattern) is used as a mark within the alignment pattern, with a color different from the color of the alignment pattern (for example, if configured In the black part of the alignment pattern, the dotted line pattern is white or a color close to this. If it is configured in the white part of the alignment pattern, the dotted line pattern is black, gray, or colored). Colors close to white include colors. As mentioned above, the size of the pattern is preferably 0.25 [mm] or less. That is, the pattern is arranged in each area formed in the alignment pattern, with one side being 0.25 [mm] or less. Among them, in addition to dotted line patterns, patterns include: striped patterns, grid patterns, mesh patterns, wavy patterns, brick patterns, and checkerboard patterns, etc.

Next, the two-dimensional code 10 shown in FIGS. 2 and 3 with tiny marks (such as text) is printed on the printed matter. On the other hand, the minute mark of the QR code 10 can only be printed by a rare printing device (for example, the printing device 60 described below). In addition, the peripheral portion of the mark is damaged, so the QR code 10 cannot be completely copied. Therefore, all products corresponding to printed materials printed with QR codes with or without micro-marks can be considered illegal products. Users (such as consumers, manufacturers of real goods, and distributors) can hardly read the mark arranged on the QR code 10 with the naked eye, but can only use a magnifying glass such as a small magnifying glass (loupe) to read it.

On the other hand, the decomposition of the QR code reader that reads the two-dimensional code 10 can be at most about 0.25 [mm] as described above. The mark placed on the QR code 10 is of small size (0.25 [mm] or less), and is formed into a symbol S without fragments due to damage at the periphery of the mark, which is recognized by the reader. Therefore, the QR code 10 can be formed To be read by the reader as if the identifier did not exist.

By using the QR code 10 illustrated in FIGS. 1 to 3 , the QR code 10 can be read by a reader. On the other hand, the user can identify the product corresponding to the printed matter printed with the QR code 10 as a genuine product. Products are identified as illegal products corresponding to printed matter printed with a code without a micro-mark. Therefore, genuine goods and illegal goods can be identified during the circulation process to stop the trading of illegal goods.

Here, the two-dimensional code 10 as the printed code 1 has been described, but the same idea can be applied to the one-dimensional code. The one-dimensional code will be explained using Figures 4 and 5.

FIG. 4 shows a one-dimensional code 20 as an example of the printed code 1. One-dimensional code 20 is also called a barcode.

One-dimensional code 20 is printed on printed matter. The one-dimensional code 20 is composed of a central data area (barcode symbol) S and left and right quiet areas Q. The one-dimensional code 20 is a type of identification code in which plural lines (bars) constituting an identification code are arranged one-dimensionally on the barcode symbol S, and information represented by characters is expressed by the thickness of each line. One-dimensional code 20 is a code that converts the information shown in text into a one-dimensional code according to certain rules. The one-dimensional code 20 can be input and output by a reader (such as a one-dimensional code reader) as easily readable digital information.

In addition, in the one-dimensional code 20, a mark is arranged in at least one line among the plural lines of the one-dimensional code 20. The logo is as mentioned above, for example, it is composed of at least one of characters and patterns.

5(A) and (B) are partial enlarged views of the one-dimensional code 20. FIG. 5(A) is an enlarged view of the first example of part D of the one-dimensional code 20 shown in FIG. 4 . On the other hand, FIG. 5(B) is an enlarged view of the second example of part D of the one-dimensional code 20 shown in FIG. 4 . Next, FIGS. 5(A) and 5(B) show an example in which the one-dimensional code 20 is provided with characters as logos. In FIGS. 5(A) and 5(B) , for convenience, the size of the characters displayed relative to part D is changed.

As shown in part D of FIG. 5(A) , the one-dimensional code 20 is attached to a part of the line, and the number "1234..." as an example of characters is used as a mark in a color different from the color of the line (for example, if the line is black and the text is white or a color close to it). Colors close to white include colors. As mentioned above, the appropriate character size is 0.25 [mm] or less. If the user uses a magnifying glass to read the text within the line (for example, white text within the black line), if the text size is 0.25 [mm], it is more appropriate to place the text on a line with a thickness of 0.25 [mm] or more. If The character size is 0.18[mm], which is suitable for arranging characters on lines with a thickness of 0.18[mm] or more.

As shown in part D of FIG. 5(B), the one-dimensional code 20 is tied to a part of the line, and the letters "JPO" as an example of the characters and the Chinese character "日本" as an example of the characters are used as marks, and the lines are Colors are configured with different colors (for example, if the line is black, the text is white or something close to that). Colors close to white include colors. As mentioned above, the appropriate character size is 0.25 [mm] or less.

Next, the one-dimensional code 20 shown in FIG. 5 and arranged with minute marks (such as text) is printed on the printed matter. On the other hand, the minute mark of the one-dimensional code 20 can only be printed by a rare printing device (for example, the printing device 60 described below). In addition, the peripheral portion of the mark is damaged, so the one-dimensional code 20 cannot be completely copied. Therefore, all products corresponding to printed materials printed with one-dimensional codes with or without micro-marks can be considered illegal products. It is almost impossible for the user to read the logo arranged on the one-dimensional code 20 with the naked eye, but it can be read using a magnifying glass.

On the other hand, the resolution of the barcode in the height direction of the barcode reader that reads the one-dimensional code 20 is very large compared to the small size (0.25 [mm] or less). The mark arranged on the line of the one-dimensional code 20 is of micro size, and is formed into a straight line without fragments due to damage at the periphery of the mark, and is recognized by the reader. Therefore, the one-dimensional code 20 can be formed as if there is no mark. And read by the reader.

Among them, the one-dimensional code 20 has been described as an example in which characters serving as marks are arranged within a part of the lines, but the invention is not limited to this case. For example, text can also be placed in a blank area with a certain width sandwiched between lines. For example, in the one-dimensional code 20, the text is placed in a part of the blank area, and the text is used as a mark and is arranged in a color different from the color of the blank area (for example, if the blank area is white, the text is black, gray, or colored).

By using the one-dimensional code 20 illustrated in FIGS. 4 and 5 , the one-dimensional code 20 can be read by a reader. On the other hand, the user can identify the product corresponding to the printed matter printed with the one-dimensional code 20 as a genuine product. , identifying products corresponding to printed materials printed with codes without micro-marks as illegal products. Therefore, genuine goods and illegal goods can be identified during the circulation process to stop the trading of illegal goods.

On the other hand, the mark may also be arranged throughout the symbol S and the quiet zone Q of the two-dimensional code 10 shown in FIG. 1 , and may also be arranged throughout the barcode symbol S and the quiet zone Q of the one-dimensional code 20 shown in FIG. 4 . Using Figure 6, the former situation will be described. The same applies to the latter.

FIG. 6(A) shows a two-dimensional code 30 as an example of the printed code 1. The two-dimensional code 30 is printed on a printed matter like the two-dimensional code 10 shown in FIG. 1 and is composed of a central data area (symbol) S and a surrounding quiet area Q. FIG. 6(B) is an enlarged view of an example of part E of the two-dimensional code 30 shown in FIG. 6(A). Next, FIG. 6(B) is an example in which characters as tiny marks are arranged on the two-dimensional code 30 . However, in FIG. 6(B) , the size of the characters displayed relative to the size of the part E is changed for convenience.

As shown in part E of FIG. 6(B) , in the QR code 30 , the letters "SAMPLE" as an example of characters are diagonally displayed throughout the symbol S (and the quiet zone Q), and are marked with a color different from the background. Color (such as black, gray, or colored) configuration. As mentioned above, the appropriate character size is 0.25 [mm] or less. In FIG. 6(B) , the characters are arranged on diagonal straight lines, but this is not limited to this case. For example, the characters may be arranged on a straight line in the horizontal direction or on a straight line in the vertical direction. In addition, the characters may not be arranged on straight lines but may be arranged on wavy lines. They may be arranged not only on one straight line (or wavy line) but also on multiple straight lines.

Next, the two-dimensional code 30 on which tiny marks (such as characters) are arranged is printed on the printed matter. On the other hand, the minute mark of the QR code 30 can only be printed by a rare printing device (for example, the printing device 60 described below). In addition, the peripheral portion of the mark is damaged, so the QR code 30 cannot be completely copied. Therefore, all products corresponding to printed materials printed with QR codes with or without micro-marks can be considered illegal products. The user can hardly read the logo arranged on the QR code 30 with the naked eye, but can only use a magnifying glass to read it.

On the other hand, the decomposition of the QR code reader that reads the two-dimensional code 30 can be at most about 0.25 [mm] as described above. The mark placed on the QR code 30 is of a small size (0.25 [mm] or less), and is recognized by the reader as a symbol S (and a plain quiet zone Q) without fragments due to damage at the periphery of the mark. Therefore, the two-dimensional code 30 can be formed to be read by the reader as if there is no identifier.

By using the QR code 30 (or one-dimensional code) illustrated in FIG. 6 , the QR code 30 can be read by a reader. On the other hand, the user can place products corresponding to the printed matter printed with the QR code 30 Identifies the product as a genuine product, and identifies the product corresponding to the printed matter printed with a code without a small mark as an illegal product. Therefore, genuine goods and illegal goods can be identified during the circulation process to stop the trading of illegal goods.

In addition, the mark may also be arranged in the quiet zone Q of the two-dimensional code 10 shown in FIG. 1 , or may be arranged in the quiet zone Q of the one-dimensional code 20 shown in FIG. 4 . The former case will be described using Figures 7 and 8. The same applies to the latter.

FIG. 7(A) shows a two-dimensional code 40 as an example of the printed code 1 . The two-dimensional code 40 is printed on a printed matter like the two-dimensional code 10 shown in FIG. 1 and is composed of a central data area (symbol) S and a surrounding quiet area Q. FIG. 7(B) is an enlarged view of an example of part F of the two-dimensional code 40 shown in FIG. 7(A). Next, FIG. 7(B) is an example of arranging characters as tiny marks in one column or a plurality of columns, for example, two columns, in the two-dimensional code 40. However, in FIG. 7(B) , the size of the characters displayed relative to the size of the part F is changed for convenience.

As shown in part F of FIG. 7(B) , the QR code 40 extends over the quiet zone Q, and the Chinese characters "Japan" and "rose" as examples of characters are marked with a color different from the color of the background ( For example, black, gray, or colored) configure 2 columns. As mentioned above, the appropriate character size is 0.25 [mm] or less.

In addition, grid lines (thin lines, medium thin lines, dotted lines, etc.) such as solid lines and dotted lines can also be arranged throughout the quiet zone Q. For example, between two columns of text, a grid line is arranged in a color different from the color of the background (for example, black, gray, or colored). The thickness of the grid lines should match the text size, preferably 0.25 [mm] or less. However, it is not limited to the case where columns of characters and ruled lines are combined and arranged throughout the quiet zone Q as shown in FIG. 7(B) . It goes without saying that only ruled lines may be arranged throughout the quiet zone Q.

On the other hand, FIG. 8(A) shows a two-dimensional code 50 as an example of the printed code 1 . The two-dimensional code 50 is printed on a printed matter like the two-dimensional code 10 shown in FIG. 1 , and is composed of a central data area (symbol) S and a surrounding quiet area Q. FIG. 8(B) is an enlarged view of an example of part G of the two-dimensional code 50 shown in FIG. 8(A) . Next, FIG. 8(B) is an example of arranging one column or a plurality of columns, for example, three columns, of characters as tiny marks in the two-dimensional code 40. However, in FIG. 8(B) , the size of the characters displayed relative to the size of the part G is changed for convenience.

As shown in part G of Fig. 8(B) , in the QR code 50, throughout the quiet zone Q except the four corners, the Chinese characters "Japan" and "rose" as examples of characters are used as logos, with colors different from the background. Configure 3 columns in a color (such as black, gray, or colored). As mentioned above, the appropriate character size is 0.25 [mm] or less.

Next, the two-dimensional codes 40 and 50 on which minute marks (for example, characters) are arranged are printed on the printed matter. On the other hand, the minute marks of the two-dimensional codes 40 and 50 can only be printed by a rare printing device (for example, the printing device 60 described below). In addition, since the peripheral parts of the marks are damaged, the two-dimensional codes 40 and 50 cannot be completely copied. . Therefore, all products corresponding to printed materials printed with QR codes with or without micro-marks can be considered illegal products. It is almost impossible for the user to read the logos arranged on the QR codes 40 and 50 with the naked eye, but they can only use a magnifying glass to read them. In addition, even if the user cannot read the logos arranged on the QR codes 40 and 50 with the naked eye, the user can still recognize the existence of the logo with the naked eye.

On the other hand, the decomposition of the QR code reader that reads the two-dimensional codes 40 and 50 can be at most about 0.25 [mm] as mentioned above. The marks placed on the QR codes 40 and 50 are of small size (0.25 [mm] or less), and the peripheral parts of the marks are destroyed to form a plain quiet zone Q and are recognized by the reader. Therefore, the QR codes can be 40 and 50 are configured to be read by the reader as if there is no identifier.

By using the two-dimensional codes 40 and 50 (or one-dimensional codes) illustrated in Figures 7 and 8, the two-dimensional codes 40 and 50 can be read by a reader. On the other hand, the user can print the corresponding two-dimensional codes. Products printed with QR codes 40 and 50 are recognized as genuine products, and products corresponding to printed products printed with codes without micro-marks are recognized as illegal products. At this time, the user can use a magnifying glass to identify the QR codes 40 and 50 as regular ones. However, even without using a magnifying glass, the user can still identify the QR codes 40 and 50 as regular ones due to the existence of tiny marks (passing lines). Therefore, genuine goods and illegal goods can be identified during the circulation process to stop the trading of illegal goods. Among them, the two-dimensional code 50 shown in Figure 8 is different from the two-dimensional code 40 shown in Figure 7. Since there are blanks (fragments) without tiny marks at the four corners of the quiet zone Q, the user can easily recognize the appearance. There are tiny marks on it.

Next, the printing device 60 for printing the printing code 1 and the printing method using the same will be described.

FIG. 9 shows a printing device 60 that prints the printing code 1 . The printing device 60 is a device that prints the printing code 1 on a printed material made of sheet-like paper, plastic, vinyl, cloth, or the like. The following describes the case where the printing device 60 prints the printing code 1 on paper.

The printing device 60 includes a paper feed roller 61, a continuous form 62, an endless strip printing plate 63, a winding roller 64, a cutting device 65, a plate body 66, a press body 67, a plate cylinder 68, and a guide. roller (also called "guide roller") 69, and ink rolls (ink roll) 70, 71.

The printing device 60 is a rotary printing machine that uses an endless belt-shaped printing plate 63 to print the printing code 1 on a continuous sheet 62 of continuous paper (roll) fed continuously by a paper feed roller 61 . Among them, the printing device 60 prints the printing code 1 on the entire surface of the continuous paper. Alternatively, the printing device 60 prints the logo (for example, as shown in FIGS. 7 and 8 ) on the continuous paper before printing a conventional printing code (excluding logos) on the continuous paper using a printing device (not shown) using the flexographic printing method. mark (passing mark)). Alternatively, after a conventional printing code is printed on the continuous paper using a printing device (not shown) using the elastomeric printing method, the printing device 60 prints a logo on the conventional printing code that has been printed (for example, FIG. 2 , at least one type of mark (pass line) shown in Figure 3, Figure 5, Figure 6(B), Figure 7, and Figure 8).

The printed continuous report 62 is wound up on the winding roller 64, or folded and stacked in a zigzag manner by a folding machine (not shown), or cut into single sheets by the cutting device 65 and stored. In the storage box (illustration omitted).

The printing device 60 includes a plate body 66 including an endless strip-shaped printing plate 63, and a press body 67 as a receiving body. The endless strip-shaped printing plate 63 is installed between the plate cylinder 68 of the plate body 66 and the freely rotatable guide roller 69 as a driven roller. The guide roller 69 is adjusted to move freely forward and backward on the plate body 66 side, and the tension of the endless strip-shaped printing plate 63 is adjusted. The endless strip-shaped printing plate 63 is externally connected with a pair of ink rollers 70 and 71 opposite to the plate body 66, and the ink is transferred to the printing surface (printing surface) of the endless strip-shaped printing plate 63.

The plate cylinder 68 and the press cylinder 67a of the plate body 66 are made of clean, medium-solid cylinders formed by cutting, etc., and the plate cylinder 68 and the press cylinder 67a are, for example, clean steel cylinders instead of hollow cylinders. The Zhongshi (steel) roller has good rotational balance and is easy to form a perfect circle. It is heavy and heavy (for example, 300 [kg]). Therefore, during printing, the plate body 66 has less looseness due to the rebound of the printing pressure. By forming the plate cylinder 68 or the pressure cylinder 67a of the plate body 66 into a solid cylinder, the deflection caused by the printing pressure can be reduced, and even if the full plate and dots are mixed in the printing, there will be no dot damage or dot damage. Or dirty, you can print the full page beautifully.

In addition, the length of one turn of the endless strip-shaped printed plate 63 in the longitudinal direction is appropriately selected from several 10 [cm] to several 10 [m]. The endless belt-shaped printing plate 63 is formed into an endless belt shape by connecting both ends of a long and slender flexible resin relief printing plate. In addition, a plurality of long printed boards, such as 400 inches, can also be connected in sequence, and finally the two ends are connected to each other, thereby forming an endless strip shape of several meters to tens of meters.

The printing device 60 shown in FIG. 9 can print the printing code 1 including the micro mark on the printed matter indicating the product. 9 will be used to illustrate that the printing device 60 prints the entire printing code 1 (including micro-marks) or prints only the micro-marks of the printing code 1. However, this is not a limitation. The printing device and The printing method is optional. It is extremely difficult to print tiny logos with a precision that can be recognized by a magnifying glass using flexographic letterpress printing or digital printing (for example, printing using a laser printer or an inkjet printer). However, this does not exclude printing the entire code 1 or only minute marks on the printed matter by flexographic printing, digital printing, or the like. Among them, even if there are printing devices that use flexographic printing, digital printing, etc. to print the entire printing code 1, or only print tiny marks, they are extremely rare and are not universal (widely distributed in the market). The printing device which makes it rare has not changed.
