Protective figure for securities, the method of printing of this pattern and securities with a protective figure

 

(57) Abstract:

The invention relates to a protective drawings for securities, to the printing of this pattern and securities with a protective figure. Protective figure for securities, in particular Bank notes, has a background consisting of at least adjacent to each other of the first and second regions. These areas have geometric patterns inherent in each of the regions, the first region has a higher color density than the second region, which forms the topic. On the second area overlapping overprint, relevant to this topic and containing geometric patterns, different from the geometric figures of the second region, and has at least one color selected in such a way as to compensate for differences in density between the two areas. To the naked eye protective figure looks homogeneous and not having a theme, but theme will be clearly visible on photocopies in a different colour from the first region, when the photocopy protective figure. Protective pattern provides easy recognition photocopies, i.e. imitations from the original securities, 3 S. and 12 C.p. f-crystals, 5 Il.

The invention relates to sm and to the method of printing such a protective pattern on the securities.

One of the main problems at the present time in the production of securities and, in particular Bank notes is the problem of creation of protective elements, which could be easily printed on Bank notes with classic printing technology and that it would be very difficult, and it is impossible to reproduce, in particular, with new generations of colour photocopiers. Due to the great progress in the technology of these machines becomes necessary to create such protective elements that would make it easy to distinguish colour photocopy, i.e. the fake from the real securities or Bank card.

The use of protective drawings to prevent fraudulent securities using a color copying apparatus is known technology. In the European patent 0384897 on the name of the same applicant, for example, describes a protective figure, composed mainly of three superimposed on each of the drawings, each drawing differs in color and consists of parallel lines oriented at an angle, and the set of lines of each image is shifted in the lateral direction so that when prestuplenie the tee, in which line segments have an orientation different from the orientation of the parallel lines, and, therefore, these lines are intermittent. In fact, these areas correspond exactly to the letters, which are almost invisible to the naked eye when applying the drawings, but can be clearly seen when making photocopies protective figure. Thus, it becomes possible to quickly and very simple recognition of the original securities and photocopies, provided applying a protective figure.

The aim of the present invention is to improve known protective drawings and, in particular, establishment of protective illustration with theme, made hidden color, invisible or nearly invisible to the naked eye on this valuable paper, however, this topic is in the hidden color will be clearly visible in the color photocopies of this securities, including photocopies made on a photocopier devices of last generation, and the creation of the printing method of this pattern and securities with the same figure.

This goal is achieved by the protective figure for securities, in particular Bank notes, with a background consisting of at least CA is isoki, inherent in each of the regions, the first region has a higher color density than the second region, which forms the subject, and the second area overlapping overprint, relevant to this topic and containing geometric patterns, different from the geometric figures of the second region, and has at least one color selected in such a way as to compensate for differences in density between the two areas, to the naked eye protective figure looks homogeneous and not having a theme, but theme will be clearly visible on photocopies in a different colour from the first region, when the photocopy protective figure.

The invention is based on the fact that, on the one hand, the background consists of two areas with straight and curved lines, while these areas have different color density and a region with a lower color density forms theme. In addition, the protective pattern is repeated printing corresponding to theme, performed by overlaying this less dense region using the color selected in such a way as to compensate for differences in color density between the two regions, and forming, thereby, a theme or riunioni eye, but will be clearly visible on photocopies in a different colour from the area with the highest color density, and the photocopy of the protective figure.

And really, when you photocopy this combination of different densities and colors creates an overlay on the level of the scanner, Photocopying machine. The contrast between the background of the protective figure and theme will be much greater when the photocopy and theme will be clearly visible on photocopies in a different colour from the rest of the protective figure that makes such falsification visible to the naked eye and makes it easy to distinguish the copy from the original.

The first region can have lots of lines printed parallel and oriented at an angle of at least two different directions, and the second area has lots of curved lines or straight lines, and overprint has a straight or curved lines, and when the overlay line overprint cross the line of the second field.

Lots of lines and lines can be grouped together in the form of a closed geometric figures.

The curved lines of the second field may be a spiral, and the lines of imprinting are straight lines.

The angle l is approximately 67,5oand the angle of the lines of imprinting of approximately 45owhile these values are approximate tolerance of 20%.

Protective pattern may contain areas of parallel lines oriented in the third direction, and the angle in the third direction approximately equal to 112.5owith an estimated tolerance of 20%.

The thickness of the straight lines may be approximately 90 m, and the distance between different lines in a single plot, measured from the center of each of the adjacent lines to be approximately 350 m, with an approximate tolerance of 20%.

The thickness of the curves can be approximately 41 m, and the distance between each curve line, measured from the center of each of the adjacent lines may be approximately 250 m, with an approximate tolerance of 20%.

The color density of the overprint may range from 0,010 to 0,300.

Geometric patterns have or triangular, or hexagonal, or rectangular, circular or other shape.

Geometric patterns can have different color and overprint can have multiple colors.

Theme or pattern hidden color predpodtitelno) or SORE" (copy). The subject may also contain one or more digits, i.e. it can be used for any topic.

Security paper according to the invention has, on at least one side of the above-described protective drawings.

Obviously, the use of such protective drawings not limited to securities and banking tickets. Indeed, the specified protective figure can also be used in cards, such as credit or other checks and stamps. This figure can be used on any printed media, forgery which the photocopy should be avoided.

A method of printing a protective pattern on the securities, in particular on Bank tickets, according to the invention contains the following steps:

printing by the first printing plate background, consisting of at least adjacent to each other of the first and second regions having geometric patterns inherent in each of the areas, and the first region has a higher color density than the density of the second region, forming the subject;

printing by the second printing plate overlay corresponding to the second region overlapping the second area of color, podobrannogo eye protection picture looks homogeneous and does not have a theme, but theme will be clearly visible on photocopies in a different colour from the first region, when the photocopy protective figure.

You can use the number of printing plates corresponding to the number of different colors.

Used printing method can be an offset printing or deep engraving.

Below is a description of a variant embodiment of the invention and related figures, illustrating the principle of the invention, depicting the following:

figure 1 depicts a known protective figure, printed in a known manner;

figure 2 - in black and white one of the backgrounds protective figure and hidden theme or pattern in the form of a cross, with the background and hidden picture shown separately;

figure 3 - different geometric patterns in an enlarged view;

figure 4 is a color photograph of protective illustration with theme in the form of the sign "X" according to the invention;

figure 5 is a color photocopy of the pictures shown in figure 4.

Colored figures illustrating the present invention, attached to this application in the form of figures 4 and 5, as the principle of the invention it is hard to show and play with black and white photos. three different colors are already superimposed on each other as a group 1 parallel and tight lines, giving the impression of a homogeneous background. Protective figure includes areas 2-4, in which parallel lines oriented in a direction different from the General direction of the lines of the background, while these areas have the shape of letters of the word "VOID". - void). The figure is an increase of the protective figure and already a copy of this picture, so the letters in the figure can easily differ. When the real size of such protective drawings these words are much more difficult to detect in the original picture. On the other hand, all the lines are straight or parts direct.

In the figure 2 von 10 protective pattern according to the invention are shown separately from the printer 20 in the form of a cross next to him, with overprint 20 is designed to print on a background of 10. The colours are difficult to reproduce using photocopies, but this example is provided as an illustration.

Background 10 protective figure is divided into areas containing triangular geometric patterns 11 that are located next to each other with the sequence. In this example, there are three types of images with different configurations of lines. In the first type of figures 11 there are only two parallel lines. In this type of drawings with ASDI 11b with a straight, oriented at an angle to the second direction, and the sections 11c straight, oriented at an angle in the third direction. In addition, the background includes the second type of figures 12 with curves in the form of spirals, and the third type of figures 13, consisting of a combination of segments of parallel lines oriented at an angle, and segments with lines in the form of a spiral. Print lines and spirals is carried out in such a way that they form an appropriate topic for the printer 20, the print overlay, while the example describes the sign "X".

Overprint 20 in this embodiment, the implementation has the form of a mark "X" in turn contains parallel lines oriented at a given angle, for example 45o. In the printing process of this imprinting 20 on the background will be effective imposition of straight and curved lines, and color overlays compensating for differences in the density of colors.

The magnitude of the orientation angles of parallel lines background and imprinting can be anything, even more important is the fact that the background has, at least, lines, oriented in two different directions, and overprint has a line oriented in the direction different from the two other o and 67.5oand the lines printed were oriented at approximately 45o. In the presence of background lines, oriented in the third direction, we choose the angle should be approximately equal to 112.5o. These values are approximately a tolerance of 20%.

The thickness of the lines printed parallel lines in the form of spirals and lines of imprinting may also change. It can range from 15 m to 100 m, Preferably, parallel lines must have a width of approximately 82,55 m, and curves a thickness of approximately 41,275 M. moreover, the lines of overprint preferably have a thickness of about 41,275 M. These values are approximate tolerance of 20%.

The distance between each printed line, measured from the center of each of the adjacent lines may range from 100 m to 800 m Selected value depends on the homogeneity to be achieved for the background and for imprinting. Preferably, this distance is approximately 349,25 m parallel lines background, approximately 247,65 m for imprinting and approximately 250 m for curves. These values are approximately a tolerance of 20%.

Density color printing, print overlay, the form, for example, triangular, hexagonal, rectangular, circular, etc.

The figure 3 shows the increased geometric figures 11, 12, which shows the segments of parallel lines oriented in three different directions corresponding to the directions of the sections 11a, 11b, 11c of figures 11 and curve segments of spiral lines corresponding to the lines in figure 12.

The figure 4 shows a color photograph of the protective pattern according to the invention with the subject mark "X" printed overlay on the background.

The background of this protective figure corresponds to the background 10 embodiments described with reference to figure 2, with alternating triangular drawings, lines are oriented in three different directions, and theme matches the overprint 20 described with reference to figure 2. In this photograph the subject in a hidden color it is difficult to distinguish from the background, which, at first glance, has a homogeneous appearance.

Figure 5 shows a color photocopy of a protective figure in figure 4. This photocopy is clearly and unambiguously manifests itself subject to a protective figure in a hidden color, with pronounced contrast and color difference between the background and the subject.

wet offset, deep engraving or a combination of these two methods. When using the offset method requires at least two plates, one for background and one for the printer. These plates can be optionally other topics and mounted on a blanket cylinder for plates. The drawings are then transferred to the cylinder for deckles, from which they are then transferred directly onto the paper. Description of such methods multicolor offset printing is, for example, in European patents 0092887, 0132858.

In the case of a combination of different printing methods can be applied, for example, how deep prints for the background, and offset method for imprinting.

The printing method of the protective pattern on securities or banking ticket according to the invention contains at least the following two stages:

printing by the first printing plate background, consisting of at least adjacent to each other of the first and second regions having geometric patterns inherent in each of the areas, and the first region has a higher color density than the second region, forming the subject;

printing by the second printing plate overlay corresponding to the second region is in the surrounding area between the two areas, while to the naked eye protective figure looks homogeneous and not having a theme, but theme will be clearly visible on photocopies in a different colour from the first region, when the photocopy protective figure.

Possible increase in the number used in the protective figure of colors. For example, geometric patterns can be of different colors and stamps to include multiple colors. In this case, the number of printing plates should be increased accordingly.

The invention is not limited to the described implementations and other choices are possible within the framework of the claimed protection.

For example, you can print a spiral line in the overprint and the background leaving only the parallel lines oriented in different directions. Repeats the same effect alternating straight and curved lines, and hear the principle of the invention.

Other types of geometric figures, for example, hexagonal, circular or any other shape.

Instead of spirals can be used curved lines, concentric circles, or ellipses, or wavy lines, or other similar shapes.
