JP4264830B2 - Printed material with characters in part of line drawing - Google Patents

Description

  The present invention is applied to printed matter that needs to prevent counterfeiting and alteration of banknotes, stock certificates, securities, passports, cards, etc., and has characters provided on the same line as the line drawing. It relates to printed matter.

  Countermeasures against counterfeiting and alteration are extremely important factors in printed matters such as banknotes, stock certificates, securities, various certificates and important documents, and financial cards. Various anti-counterfeiting measures such as anti-counterfeiting measures, copy prevention measures by using minute characters and special ink, and anti-counterfeiting measures for machine reading to mechanically determine that the printed product is genuine when using precious printed matter It is known to apply measures to printed matter.

  Among these various anti-counterfeiting measures, it is confirmed as an image line by the naked eye, but when enlarged, it is composed of minute characters, and when copied by a copying machine, it is merely an image due to the limit of reproducibility of the copying machine. The minute character that is reproduced as a line is a technique that has been widely used in recent years as a general technique.

  In particular, by arranging minute characters in succession to the image line, everything can be recognized by the naked eye as an image line, and when copied, the minute character is not reproduced. (For example, patent document 1).

Japanese Patent No. 3392892

  However, the minute character is not completely recognized due to the difference between the shape of the image line and the character, but it is such that it looks like an image line, and its main purpose is to prevent copying. Therefore, once the existence of minute characters is clarified, the effect of fading / alteration prevention measures has been diminished compared to the past due to recent image processing techniques.

  This is also the case with the above-mentioned Japanese Patent No. 3392922, in which minute characters are applied to a part of the image line, because minute characters are continuously applied to the image line so as to be recognized as the image line. Since the characters themselves cannot be recognized by the naked eye, it is necessary to use an auxiliary tool such as a loupe for the confirmation.

  Therefore, the present invention does not limit the pattern that constitutes the printed matter, and by randomly constructing characters and / or symbols formed using a part of the image line, the line image pattern is simply configured with the naked eye. However, only for those who know the information, we propose a printed material that can recognize the existence of the character and / or symbol as a genuine product without using an auxiliary tool such as a loupe. For the purpose.

  In the printed matter in which a pattern using an image line is applied to at least a part on a base material, the character and / or symbol is applied to at least a part of the image line to form the character and / or the symbol. A part of the printed matter is a printed matter formed by an image line.

  Further, the present invention is a printed matter, wherein the characters and / or symbols have a size of 200 μm to 1,000 μm.

  Further, the present invention is a printed matter characterized by having a gap of 30 μm to 200 μm between a character and / or symbol provided on the same line as the image line and the image line.

  Furthermore, the present invention is a printed matter characterized in that characters and / or symbols are provided at intersections where two or more image lines intersect.

  According to the present invention, in order to form characters and the like that share a part of the image line, it is sufficient that the image line is used in various components constituting the printed matter, and there is almost no restriction on the pattern. The technology that becomes the appraisal element can be applied.

  Conventional minute characters are configured as minute character groups so that they can be recognized as lines by the naked eye. However, the main purpose is not reproduced faithfully when copied, but becomes lines. Therefore, since it can be differentiated from genuine products and is configured as a group, it can be confirmed once because it can be confirmed where it is applied when carefully observing the genuine product with the naked eye In view of the current high-performance image processing apparatus, the forgery prevention effect is slightly reduced. According to the present invention, each character and / or symbol can be randomly applied individually, and since a character is formed by sharing a part of the image line, it is visually recognized as an image line. Therefore, it is very difficult to confirm the existence itself, and it is not noticed that the anti-counterfeiting technology itself is applied, so that the anti-counterfeiting effect is high, particularly as an appraisal element.

  In the present invention, since characters and / or symbols are formed using a part of the drawing line, the characters and / or symbols can be recognized assimilated with the drawing line, and not limited to a single drawing line. Since a single character and / or symbol can be formed using a plurality of patterns in a pattern composed of a plurality of patterns such as a colored pattern, one character and / or symbol itself is not necessary. However, the existence cannot be grasped by anyone other than the designer and the person who acquires the information. Therefore, it is possible to determine authenticity without using an auxiliary tool such as a loupe like a minute character.

  An embodiment of a printed material having characters and / or symbols in a part of an image line according to the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an entire printed matter in which a line drawing pattern having characters and / or symbols is applied to a part of the drawing line in the present invention. In this figure, a line drawing pattern as a background and a colored pattern (2) having characters and / or symbols are applied to the entire surface of the substrate (1). However, in carrying out the present invention, FIG. Such a background line drawing pattern does not have to be present, and the colored pattern (2) having characters and / or symbols may be either the entire surface or a part of the substrate (1). Therefore, in order to implement the present invention, it can be realized by applying at least one image line somewhere on the base material (1). The size of the substrate is not limited.

  FIG. 1 is intended for printed materials such as securities and passports, and the line width of the background and the color pattern is 30 to 200 μm, preferably 60 to 150 μm. However, when the line width is narrow, if characters and / or symbols are placed on a single line, the characters and / or symbols stand out. Therefore, when using a thin line width, characters and / or It is desirable to use the intersection of the strokes as the location where the symbol is given. The case of using this intersection will be described later.

  FIG. 2 is a diagram showing a state in which a character (3) is applied to a part of the chromatic pattern (2) in FIG. As shown in the enlarged view in FIG. 2, two characters (3) are applied in close locations. However, the number of characters and / or symbols may be one or more. They can be close or separate. By applying one or more characters, it is possible to apply the code as intended by the designer. Furthermore, two or more characters and / or symbols can be provided on a single line.

  The size of characters and / or symbols is in the range of 100 to 1,000 μm, preferably 300 to 600 μm, in the case of printed materials such as securities and passports as shown in FIG. If it is smaller than 100 μm, it is difficult to recognize it as characters and / or symbols when printed, and if it exceeds 1,000 μm, the characters and / or symbols can be recognized on the printed material at a glance. Note that the size of characters and / or symbols in the present invention means the character height (y) or character width (x) in FIG. 4, and when the character height and character width are not equal, When setting symbols, the smaller character height and character width are used as a reference, and when setting larger characters and / or symbols, the larger character height and character width are used as a reference.

  Further, as shown in the enlarged view of FIG. 2, there is a gap between the applied character and / or symbol and the drawing line, but this gap is not necessarily required. Alternatively, a part of the symbol and the image line may be configured continuously. However, in order to make it easy to recognize as characters and / or symbols, it is desirable to have a slight gap. About this clearance gap, it is the range of 30-200 micrometers, Preferably it is 50-150 micrometers.

  However, the line width, the size of characters and / or symbols mentioned above, and the gap between the line and characters and / or symbols are those when using general printing paper such as securities and passports. If the target printed material is relatively large, such as a poster, the line width, the size of characters and / or symbols, and the line and characters and / or symbols are matched. It is possible to carry out the present invention by setting a gap between them.

  FIG. 3 shows a flow for creating a line drawing pattern in which characters and / or symbols are applied to a part of the drawing line in the present invention. First, an arbitrary line drawing pattern to be printed is created. Next, an arbitrary character and / or symbol applied to the line drawing pattern is determined. These characters and / or symbols are determined by the designer or the orderer of the product according to the printed matter (product). It is desirable that the characters and / or symbols to be applied basically become certain information when extracted and rearranged. This is because the information can be used as a means for determining authenticity particularly when applied to precious printed matter. When the character and / or symbol to be applied is determined, the place where the character and / or symbol is applied is determined based on the shape and density of the stroke, the stroke width, the color, and the like. After the character and / or symbol to be applied and the place are determined, the image line forming the character and / or symbol or pattern is deformed so that the line image pattern does not feel uncomfortable. 3 and 4 are diagrams showing this modification.

  FIG. 3 is a diagram showing a deformed state of characters and / or symbols. The original character (4) (here, the letter E) is combined with the angle and arrangement of the image lines constituting the colored pattern (2). Is in a deformed state. FIG. 4 shows a state in which it is deformed together with the character (4) (here, alphabet A) to which the image line of the chromatic pattern (2) for applying the character and / or symbol is applied.

  After the transformation of the character and / or symbol and the drawing line (if necessary) is completed, the character and / or symbol is actually applied to a part of the drawing line, and adjustment as a line drawing pattern is performed. This adjustment examines the impact on final color, platemaking and other designs and technologies (especially anti-counterfeiting technology). Various adjustments are also included in the data that is finally completed as an image by this adjustment to a format for actual output.

The printed image is obtained by outputting the completed image directly to the film, creating a printing plate suitable for the desired printing method from the film, and printing it. The printing method is not particularly limited as long as it is a method capable of printing a line drawing pattern, such as intaglio printing, relief printing, offset printing, screen printing, and the like.
For the above creation methods, use commercially available line drawing software (drawing software: software that has lines as position, data, line type, and paint data, and makes graphics based on line drawings by combining them). For example, there are Adobe Illustrator and Macromedia FREEHAND.

  FIG. 6 shows examples of characters and / or symbols in the present invention, and illustrates hiragana (a), katakana (b), romaji (c), numerals (d), and various symbols (e). Any character and / or symbol that can be applied to the line drawing pattern can be used.

Example 1
The chromatic pattern shown in FIG. 2 was created using line drawing software (draw type Adobe Illustrator). The stroke width is basically 80 μm, and the characters “na” and “n” of katakana with a size of 500 μm are given. In this case, a space of 50 μm was provided between the character and the image line, and the place applied from the shape of the character was defined as the intersection of the image lines. The color of the pattern is not particularly limited, but in this embodiment, since a gap is provided between the character and the image line, a light-colored yellow is used so that the gap is not conspicuous. Printing was performed by the offset printing method using green. When a person who does not know that the letter is given to this printed matter, it was impossible to recognize the letter that was given, but when the part was specified and checked with a magnifier, The letters “na” and “n” were clearly recognizable.

(Example 2)
The chromatic pattern shown in FIG. 2 was created using the line width (5) and the size of the character (3) as shown in FIG. In FIG. 7A, the line width is 50 μm, the character is “E” in Roman letters, the size is 150 μm, and the gap between the line and the character is 40 μm. (B) is an image line width of 130 μm, a character is “E” in Roman letters, a size is 250 μm, and a gap between the image line and the character is 80 μm. In FIG. 7, the character (3) is given on one image line, but the configuration as shown in FIG. 8 was also created from the shape of the character “E” in consideration of the consistency with the image line. The image line width is the same as FIG. 7 (a) is 130 μm, (b) is 50 μm, and the space between the image line and the characters is 50 μm, the same as in FIG. The character size was set to 500 μm, the same as in FIG. Considering the shape of the character as shown in FIG. 7, it is more effective to apply characters using the intersections of several lines and lines than to apply one character on one line. It can be expressed without a sense of incongruity.

(Example 3)
FIG. 9 is a diagram illustrating a case where the density of the chromatic pattern is varied. (A) shows a case where the density is low, and is printed in light yellow, and (b) shows a case where the density is high, and is printed in blue. The character type, line width, character size, and gap between the line and the character are the same as those shown in FIG. 2, and only the colors used are different. For this color, normal ink is used. However, when fluorescent ink is used, a new effect appears as shown in FIG.

(Example 4)
As described above, FIG. 10 is a diagram showing a color pattern using colored fluorescent ink. It is difficult to recognize the presence of a character applied to the character and the image line not related to the character with the naked eye, but it is printed with the colored fluorescent ink by irradiating ultraviolet rays (6). The lighted portion emits light, and particularly the character portion can be clearly recognized. Note that the character type, line width, character size, and space between the line and the character are the same as those shown in FIG. In this embodiment, colored fluorescent ink is used, but colorless fluorescent ink may be used.

(Example 5)
FIG. 11 is a diagram showing an embodiment according to the type of characters and symbols shown in FIG. (A) shows "na" of hiragana, (b) shows "%" of the symbol, and (c) shows "mo" of katakana. In any case, the character type, color, line width, character size, and gap between the line and the character are the same as those shown in FIG. The places where the characters and symbols are applied are examined so that the characters and symbols are given a sense of incongruity.

(Example 6)
FIG. 12 is a diagram showing an example of a place where characters and symbols are applied. (A) is the form which gave the character to the intersection of drawing lines like other Examples, and is a form which shows an effect more in this invention. (B) is a letter with two nearly parallel strokes, with the letter “H” in Roman letters, and (c) with the letter katakana “G” on one stroke. It has been applied. Although the type of character and the place to be applied are different, the color of the character, the line width, the size of the character, and the gap between the line and the character are the same as those shown in FIG.
