The present invention relates to a storage medium, sealed by the method of metallographic printing, as well as to a method for converting any of the original images, i.e. images or originals of any narrative content, the printing elements of the printing form for metallographic printing.

Printed forms used for gravure printing, supply their carrying paint the areas of the grooves. In the process of printing these grooves are filled with printing ink, the excess of which is removed from the surface of the printing form erasing roller or squeegee, resulting printing ink remains only in the grooves, and then print the form with a deposited ink is pressed against the printed basis, which is usually paper. Subsequent separation of the backing from the printed forms printing ink made from the surface of the printing form recesses is transferred onto the canvas. Methods gravure printing is divided into autodeploy gravure printing and metallographic printing.

Under normal autodeploy gravure print on an appropriate basis is created using made in printed form small, located very close to each other, but separated from other cells to be filled in the printing process is relatively flowable printing ink. Printing ink after the case is as printed on the basis of a blur, resulting in clearly defined boundaries between the individual raster points in the image disappear and these dots are merged. Transfer the imprint of the different gray tones and color tones is provided at autodeploy gravure transfer printed on the basis of different amounts of printing ink, which is achieved either by varying the density of the cells, or by varying their depth and size.

Unlike autodeploy gravure used for metallographic printing-carrying paint depressions in the surface of the printing form is made not in the form of halftone dots, and usually in the form of lines. In the printing process, the base material under the action of extremely high pressure clamp to print the form, respectively, to the printing cylinder, also undergoes a permanent deformation, acquiring relief or embossed structure. Used for metallographic printing printing ink has a pasty consistency and so after her shift on the basis not spread out on it, but retains the shape of its deepening in printed form, and for this reason, when a sufficient thickness of the paint layer may, after drying, to form not only visually discernible, and discernible to the touch patterns.

In the manufacture of printing forms for metallogr the Russian printing traditional method is reproducible on the basis of the original image is present in the form of linear structures, accordingly decompose the linear structure and components of their line manually cut in a metal plate the plate. In principle, such "engraved metal plate the plate can be used directly as a printing plate, however, it is usually first multiply common methods of fabrication with her secondary forms and electroplating. Handmade original printed forms to get her imprint, which is quite realistic and accurate detail reproduces the original image, makes extremely high demands on artistic and professional abilities and skills of the engraver, but practically it is not possible inclusion in the engraved image changes and adjustments, and also associated with a significant amount of time and money. For this reason, it is often first create a so-called "painted picture", for which the first stage is played in the following in the form of a print original image by drawing is converted into a linear structure. Although this technology provides several great opportunities to change and correction generated in this way of drawing compared to the direct engraving image in the metal plate, the whole, however, such opportunities are still limited. However, professional and artistic abilities and skills of the artist are the same high requirements as in the above case, the direct execution of the image in the metal plate engraving.

This hand-drawn picture you can transfer photographic methods on a transparent film that is then exposed layer of photoresist deposited on the surface of the printing form. Then, the surface of the printing form on the sections corresponding to the lines of the figure, remove the unexposed photoresist and then on these sites perform etching of the cavities to be filled in later printed ink. Depth is achieved as by grooves alongside the duration of the etching depends on the width of the lines, since at a constant duration of etching fine lines mytravelguide a lesser depth than the depth of etching of wide lines. The etching in this method the surface of the printing form recesses with substantially different and is practically independent of line width depth possible only in a considerably limited by repetition of the stages of etching. At the same time between different stages of etching the surface of printing army you want to cover in separate areas of additional masking layers or remove them from the surface of the printing form on its separate parts. However, such additional operations are greatly complicates and increases the cost of manufacturing process of the printed form. In addition, in the manufacture of printed forms for this technology fineness performed by such structures is limited, and the etching can not be perfectly reproducible.

From the application WO 97/48555 known method, allowing engraving to transfer of the pattern on the surface of the printing form. For each stroke of such a figure is calculated separately passing along the path of the stroke path of movement of the engraving tool. Although such technology and has no limitations, which are inherent in the method of manufacturing the printed forms of etching, however, a necessary prerequisite for the implementation of this method is also time-consuming and inflexible creating hand-drawn prints, which does not provide any opportunities for further changes.

From the application WO 83/00570 known way to reproduce a halftone image using a randomly selected raster elements. All occupied by the image area is covered by orderly arranged raster elements, and to transmit the intensity of colours one or another area of the image corresponding to the image area is raster element are in the form of strokes of a certain thickness, tentatively correlated with the respective intensity of the tone. However, when using such evenly distributed throughout occupied by the image of a square raster structures obtained with them the imprint gives the impression of an artificial, unrealistic image that refers primarily to portrait images. In addition, in this image usually there are always areas where the geometry of the raster element distinct and thus is not difficult to play a potential falsifiers. Because the raster is constant throughout occupied by the image of the square structure, rasterized in a similar way the prints are relatively easy to reproduce and to forge.

The present invention was used to develop the media information obtained on which method of metallographic printing imprint would be more complex performance or appearance and due to this possessed a higher degree of protection against forgery. Another objective of the present invention was to develop a method which would allow to carry on the printed form of the original image, any content and which would be inherent in the known from the prior art solutions of the constraints. This method should ensure that before is this a faster and flexible conversion of the original image, as well as the ability to easily make changes in the graphical representation of the transformed source image and the adjustment and the possibility of more complex formatting print (printed image).

This is accomplished by using the appropriate media and appropriate method presented in the independent claims. Preferred embodiments of the invention are given in the respective dependent claims. Proposed in the present invention the media is printed by the method of metallographic printing a grayscale image, which is made in the style of engraving. In other words, all the contours, contrasts and tonal gradation reproduced in the impression of the original image is transmitted by using an irregular or disordered linear structures, the distance between which and the width of lines, as well as the geometry and the type in which the print purposefully vary to create different visual impressions. The stamp consists of a repeating print of structural elements, such as lines or intersecting lines, which are at least partially superimposed fine structure. Integrated in the structural elements of small patterns can greatly increase the complexity of the impression and because of this it is vital which inhibit its falsification and forgery. In addition to this fine structure can further modify the generated structural elements of the visual impression. At the same time, however, there are still inherent in the technique of engraving the image expressiveness and realism that is achieved through individual design and location of linear structures.

Fine patterns can be formed by whitespace, i.e. unsealed, areas that are present within the printed structural elements, which may be continuous or preryvayuscheesya through uniform or non-uniform intervals. In addition to this printed structural elements can be interrupted or "hide" the application of fine patterns, i.e. replace the original painted area of the structural elements on a separate printed characters or characters that are playable in the form of a positive image. This saves only the outlines of the structural elements in their path. Small structures can be reproduced text labels of any content and design, alphanumeric characters, logos, symbols, geometric shapes, or other visual elements.

Small patterns with their corresponding design can carry visually distinct or hidden, identifiable only with the use of technical auxiliary materials is lnyh funds additional information or may be made in the form of visually distinct or hidden, recognized only with the use of technical AIDS signs of authenticity. Small patterns can be performed in the form of copy-protected structures.

When playing fine structures in the form of a negative image, i.e. in the form of white-space plots sealed on the background, it is preferable to perform primarily in the form of lines or intersections can have a different design. So, for example, on a printed line may include passing along it unsealed line, which can be in the form of a double line consisting of several separate lines. Preferably, such unsealed line was held exactly parallel to the geometric midline of the printed line. When this space areas may be in the form of characters, patterns, symbols, reproducing, for example, human-readable text or logo of the manufacturer. The presence of such text or symbols depending on their size simply visually check without using or using assistive devices, such as magnifiers.

If the structural element is formed by intersecting lines, whitespace can be performed before the entire area of their intersection or passing parallel to the plot of one of the intersecting lines are Equal in this way the intersection of the lines, you can perform a space area in the form of a sign or symbol of any arbitrary shape, which thus will be played in the form of a negative image.

When playing a small structure in the form of a positive image of the structural element, for example, the line may be interrupted by any individual or symbols printed in black and white. Such signs or symbols, which can either be connected to another, or to defend from each other, preferably located along the geometric average of the interrupted line or lines. When such signs or symbols can have constant or varying sizes (height). If interrupted line has varying along its length, width, according to one of the preferred variants of such a line, it is advisable to completely stop labeling its longitudinal edges with marks or symbols, dimensions, and/or stroke thickness which varies in accordance with the changing width of the line.

For reliable from the point of view of media playback fine structures for their implementation in the form of a positive image, it is preferable to apply the finishing touches with a thickness that is greater than or equal to 25 μm, and when they are executed in the form of a negative image, it is preferable to use white-space plots, whose clear width is 35 μm or more. Positive and negative images can be combined with each other in Liu who's combinations. Thus, in particular, images of both types can not only be placed within the impression in different places, but also to combine, within a single structural element, having them in all places and in any sequence. Regardless of whether small-scale structure in the form of positive or negative images, characters and/or symbols can be combined with each other within a single structural element in all their combinations, and on the adjacent structural elements to provide the same regularly alternating or absolutely other small structures. Fine structure is preferably applied to the linear structure in which the width of the lines in the print is at least 200 microns.

To obtain a halftone image on offer in the invention of the media, first in accordance with the proposed invention is the way the original image is converted into a set of digital data representing graphical data in the form of pixel data, which is decomposed original image. Next, the original image are available for visual perception based on the data of its pixels, and in this form it can be used as original or layout for subsequent graphical transformations that the original image is to be placed in a kind of hand-drawn picture. During this transformation in the system of electronic data processing on the basis of the operator's commands are individual linear structure, reproducing the contours and tones of the original image. For those portions of the image that should create a different visual impression created by different line patterns. Digital image data describing the thus obtained linear patterns are stored in the vector-based graphics format. If necessary, separate lines are linear structures, or related graphics data are being processed in the system of electronic data processing. This way you can increase the attention to detail reproduced in the printed image or some plot or change the generated image or some of its plot visual impression for the transmission of some of its nuances. Subjected, if necessary, similar to the processing of digital image data are stored in the same format vector graphics. Then, these image data are used to control the precision engraving device, in which the surface of the blank printing plate for metallographic printing is performed corresponding to the above-described linear structures deepening.

A special advantage of this method of manufacture the Oia printed forms for metallographic printing it is possible to eliminate the intermediate stage of creating hand-drawn prints on physically existing tangible medium by the output corresponding to digital image data to the printer or imaging device for exhibiting films. Unlike proposed in the invention method in the manufacture of printing forms traditional methods of engraving or etching such intermediate stage is required. Because each additional intermediate stage or operation in the manufacturing process of the printing form is not only associated with the corresponding time and cost, but also is a potential source of various kinds of errors proposed in the invention method provides not only faster and more economical, and more reliable production of printing forms. Considering further the fact that the creation of hand-drawn prints on a tangible medium and its subsequent use in the process of engraving or etching inevitably associated with the occurrence of certain errors proposed in the invention method enables the direct post-processing of digital image data to convert the original image to the printing elements of the printing form for metallographic printing with greater attention to detail and with more precise dimensions. In addition there is also the possibility of a simple way to replace stored in digital form the original image some of his fra the COP, presenting his modified linear structures, such as provided by the invention of the fine structure. Electronic data processing allows to scale the original image, rotate it and create mirroring without having to change anything in the real form of the figure, which is always at a constant size. In addition, it eliminates the need to print the image, or the wrap on the exposed film after each change.

In the context of the present invention, according to which the original image is irregular linear structures, such linear structures refers to not only a continuous or discontinuous line, but dashed, dash-dotted and dashed lines.

According to the present invention a linear structure can be also formed by geometric symbols located along the mathematical line at regular intervals.

In accordance with the present invention engraving blanks printed forms may lie in its machining method such as milling, Sabrina or planing, as well as its processing contactless methods of material removal, such as engraving with a laser beam. Pre is respectful methods of precision milling. Engraved plate can be used either directly as a printing plate, or the quality of the original common methods of manufacturing the secondary forms and reproduction, which are directly used in the following metallographic printing of the printing form.

If image data required for carrying out the invention method has yet to be presented in the form of file digital image data, the original image is first required to enter into the electronic system and converted into digital form. To this end, first with the original image transferred to the printing form, make a copy or snapshot, which decompose into individual picture elements called "pixels". For each image element in addition to its coordinates determine its optical density in the gray scale or the optical density of the color. The choice to copy or remove the original object no restrictions. For example, the original can serve as real-world objects such as sculptures, buildings or landscapes, as well as grayscale images, such as photographs or paintings. For conversion into digital form of the original images, which are already represented in the form of a copy or snapshot, predpochtitelney scanner, which, obviously, must ensure that the scanning with the corresponding resolution. For conversion into digital form of the image of a real object, it is preferable to use a video camera or a digital camera. The resulting digital image data, referred to as "pixel data", save in the appropriate memory that allows you to perform subsequent phases proposed in the invention method, independently of each other in time.

Next, the digitized image is based on data of pixels available for visual perception, preferably reproduced on the monitor screen. If necessary, spread out on the pixels of the image are retouching by electronic means, which involves the processing of data of its pixels in the system of electronic data processing. Such retouching may consist in the removal of unwanted image parts, increase or decrease the sharpness of the edges or change the contrast of the image and, if necessary, only its individual parts.

Then similar to the manual process of creating hand-drawn prints in electronic data processing according to the operator's commands are formed irregular linear patterns, reproducing the contours and tones source the th image, portable on the printed form. The original image presented on the basis of its pixels available for visual perception, it is preferable to use as the background of the original. The process of converting the original image into a linear structure can be greatly helped if the digitized original image, visually reproduced on the basis of the data of pixels on which it was laid out to display on the monitor screen in the background, on which the operator are required linear structure. The direction and shape created by the operator of the lines can set them manually, while lying in the same plane coordinates, describing the direction and the shape of the line, are recorded by appropriate means of the input and transmitted to the data processing system. As such inputs are used, it is advisable to use primarily a graphics tablet or a mouse, but with the same purpose can be used and the so-called trackball or joystick.

Digital image data containing information created in this way linear structures are saved as vector graphics. To store data describing a graphical image primarily extremely high resolution, formalevening graphics require less memory, than to store data describing a graphical image of the same resolution, format raster (bitmap) graphics. Reducing the amount of stored data allows you to speed up the processing at the subsequent stages.

When creating and processing the linear structures that are sufficiently realistic and accurate detail to reproduce the original image, linear patterns at each modification is preferably immediately submit to visual perception. Thus the operator at any stage can in real time to visually track, for example on the screen of the monitor, all made in the image changes and to monitor their effect on the appearance of the image and created them visual impression. In the process of processing digital image data, which contains information about the linear structures, structural elements, such as lines or points of their intersection, it is possible to purposefully change. After that processed this way, the digital image data stored in memory and then, at any later point in time can be used directly to control the precision engraving device. In this case, the processed image data should be stored in the same vector-based graphics format.

Management is of the engraving device is in control of his movement when performing in the surface of the printing form for metallographic printing recesses, designed to fill the printing ink, in accordance with the direction and geometry of linear structures, presented in the form of digital image data.

In principle, in the manufacture of printing forms proposed in the invention method for depth cuts in printed form lines you can set does not depend on its thickness value. This value can be a constant for all of the engraving lines or for some parts, but in another embodiment it can also be calculated under software control, in accordance with some given mathematical expression depending on the thickness of the particular line. In addition, the operator can also specify any depth of engraving for only one single line, for a certain length of one line or group of lines, provided that the value of this depth of engraving does not extend beyond the technological capabilities of the respective equipment. It is obvious that such technological limitations relate primarily to the setting depth of the engraving lines of small width.

Proposed in the invention method enables simple processing of the printed image, especially processing used according to the invention the structural elements. You can purposefully change is first of all the width of individual lines and geometric shape of their ends. For example, the ends of the lines you can make a square, semicircular or pointed form. In addition, a separate line may thicken, utonet or distort or change their basic geometric shape. While located at opposite sides of the line can not be given mutually parallel and curved in mutually opposite directions form in the result of such line or some of its segment will lenticular or spear form. All the above processing operations can be applied to one line or simultaneously to the whole group of lines, which plays some of the whole image area. In addition, when the implementation of the proposed in the invention method, engraving printed in the form of grooves, the imprint of which is the line material from the blank printing plate can not be removed across the occupied such a line space, leaving not engraved stretch along its geometric midline. When engraving line only along both its longitudinal edges instead of a solid line is formed by a double line of the same width. The invention provides further for more new opportunities for the design of structural elements consisting of mutually intersecting lines. So, for example, digital graphics Dan is haunted, on the basis of the engraving can be processed in such a way as to leave the intersection point of the lines is not engraved. In this case, the prints obtained on media with the respective printing plates, printing ink will not appear in the intersection of the lines. In another embodiment of the two mutually intersecting lines can be engraved and thereby perform a continuous one, and the other line can not continue in the place of its intersection with the first line, i.e. to perform its interrupted, resulting in the two parts of this interrupted line will not be in contact with crossing it by a continuous line. According to another variant of the line can not only be performed in a double line, but at least its separate parts to give it a frilly look or appearance of the fringe.

The equipment required for the manufacture of printed forms for metallographic printing, and equipment necessary for the actual printing process with such forms, as well as appropriate technologies are available to only a relatively limited number of enterprises and require significant financial costs. Given that the need for such a high cost creates significant barriers potential falsifier the m and persons "specializing" in the counterfeiting of valuable documents and papers, the method of metallographic printing is mainly used for printing securities and counterfeit papers and documents, for example for the manufacture of banknotes, shares, passports, identity cards, high quality entrance tickets to various events and similar documents. Proposed in the invention is a method of making printing plates for metallographic printing allows you to convert the above-described structural elements in its printed elements with such high accuracy and detail that they can be printed in such form the impression in visually perceptible form or in the form of protective signs, to check the existence of which is possible only with the help of a magnifying glass.

Above on the example of the manufacture of printed forms for metallographic printing method of creating an image represented by an irregular line structures, in principle, can be used to create the originals or printed forms printing other methods. Because the transformation of some of the original image with its view, decorated in the style of the engravings, by the above method so far not been implemented because, according to the present invention for the first time was before ogino be applied to linear patterns, which presents such an image, extra fine structure, the advantage of the proposed invention the method consists in the possibility of displaying the created in accordance with digital image data for further processing, for example, on a digital printer, the exposure device for exposing films or plates or other means of digital printing. The above transformation capabilities of the original images stored in their views of such features as realism, individuality and complexity allow the use proposed in the invention method of achieving the same advantages and in relation to other methods of printing, such as offset printing.

Other advantages of the invention discussed below in more detail by the example of some variants of its implementation with reference to the accompanying drawings on which is shown:

figure 1 - portrait in the style of the engravings

figure 2 is a fragment of a conventional hand-drawn prints without small structures

figure 3-8 - fragment of hand-drawn prints with various small structures

figure 9 - different versions of intersecting lines using small structures.

Figure 1 shows a portrait of a man, made in the style of engraving. Ins and words, all the contours and elements of such a portrait image is reproduced, as is customary in the art of graphic presentation in the form of engravings, with varying linear structures. Such linear structures can consist of continuous or intermittent lines, as seen, for example, in those areas of the portrait image, which depicts the coat and beard, or dashed or dotted lines, as seen, for example, in the areas of portrait images which depict the ear, cheek and forehead of the person. In accordance with known prior art methods such images either directly manually cut in the surface of a metal plate, or manually draw on paper. When converting the original image in the cartoon engraving transmission of various shades, as well as the values of optical density and optical density on a grey scale is achieved through the use in having different saturation tone areas of the image of the linear structures of different types and/or by varying the width of the lines and the distance between them. Thus, in particular, highlights, which is shown on the drawing portrait image are, for example, plots, which depict the forehead, cheeks, and ear of a person, preferably reproduced with p the power of thin, relatively far from each other lines, which are in addition executed dashed, dash-dotted, or dashed. Dark areas, which is shown on the drawing portrait image are, for example, plots, which depict the hat or coat, preferably played by a wide, located close to each other lines. To obtain the imprint of dark areas or to create an optical impression of changing the lightness of tone, as, for example, in those areas of the image, which depicts the coat or the side surface of the human nose, the first group of nearly parallel lines, hereinafter called the "main layer", it is possible to impose the so-called "extra layer"consisting of the second group are also almost parallel lines.

When the conversion is similar to the original image in the printing elements of the printing form for metallographic printing proposed in the invention is a method for original prints, in the form which presents a portrait image could, for example, to serve as a snapshot of a picture obtained by a digital camera and converted in digital form. Then the graphic image, the graphic data which were saved in format, based on his view point races is RA (pixels), has been retouched by electronic means, which consists in changing the contrast of individual sections of the image. Usually in the impression it is advisable to emphasize or weaken the transitions with pronounced contours (such as the folds of the clothes or the shape of the nose). It was found that the subsequent working operations to transform the original image into an image on a printing form can be significantly easier if broken down into pixels retouched graphic image to present to the visual perception by the operator, for example to play back on the monitor screen. However, such an image is displayed based on the data of its pixels, on which it was laid out, serves as a background against which the operator's commands are linear patterns, reproducing the individual elements and the details of the portrait. The direction and shape of lines specified by the operator using, for example, tablet, recording the coordinates are moved by it in accordance with the direction and shape of the generated line scanner and transmitting these coordinates in a data processing system. If the basic geometrical parameters of the line and its width set in advance, then this line is required in its execution may, in real-time play e is wound monitor, allowing the operator to directly control their actions. Thus this process of creating lines by operator in combination with simultaneous visual display generated line on the monitor screen essentially corresponds to the free drawing, but it has before him a significant advantage in any subsequent processing each formed from e by linear structures. For example, in the already formed line in the following it is possible without any problems to make various changes, in particular to lengthen or shorten it, change its width along its entire length or only in selected areas, to bend it or to change the geometric shape of its ends. So, for example, shown in figure 1 portrait image most of the lines with which reproduces the image of the right side of the coat, have blunt rectangular ends, while most of the lines, which reproduces the image of the beard and hair on the human head, have sharp pointed ends. The ends of the lines can also give a semicircular shape, as well as any other asymmetric or created by the user geometrical form. All such changes and processing operations can be either a separate line, libaudiofile whole groups of lines, together reproducing some region of the image.

When processing digital image data, which contains information about the linear structures, individual lines or groups can be set in compliance with a certain depth of their engraving. For example, the linear structure of the base layer, you can engrave a larger or smaller depth compared to the depth of engraving linear structures corresponding "additional layer"overlay "main layer". In addition, each of the individual lines, which among other things are very tight, respectively, very close to each other, and which have the same or different width, you can engrave on different depth substantially different from the depth of engraving adjacent lines. For example, one of the two very closely spaced to each other lines of the same width can be engraved in the surface of the printing form for metallographic printing at a depth of 10 μm, and the other of them to a depth of 150 μm. Traditional etching technology to perform in printed form two adjacent lines so different depths impossible.

Figure 2-8 shows a portion of a hand-drawn prints, in which the above portrait. In the upper left part of the image is partially visible contour of a human face is in the middle and lower right parts of the image shows a portion of the collar of clothes and shoulder 1. These portions of the image clearly shows that the various sections are reproduced, i.e. the varying and thus generally irregular linear structures.

Figure 2 shows a fragment of a portrait image, which is performed in accordance with the prior art and consists of linear structures formed solid and preryvayuscheesya, and partially intersecting lines. When this individual lines do not have the additional substructures or small structures.

Figure 3 linear patterns, reproducing the image of the right shoulder 1 person, superimposed fine structure. In this example, this small structure is formed by a blank sealed areas on the background formed by the horizontal lines. Such space stations form reproduced in the form of a negative image lines, which are located exactly on the middle line of the printed lines forming a sealed background. Thin line in the "additional layer" diagonal lines "base layer", is made continuous, and therefore white-space plots, i.e. the negative line, interrupted in places mutually crossing lines "basic" and "additional layers".

Shown in the figure 4 embodiment, the thin line in the "additional layer" diagonal lines "the main word is", interrupted white-space plots in the "main layer"formed by horizontal lines. Thus space areas in the primary layer have the form of a continuous curved lines.

Shown in the figure 5 embodiment, each of the spacing sections in horizontal lines "base layer", which reproduces the image of the shoulder 1 person, forms an extremely thin double line in the form of a negative image, which also runs exactly parallel to the geometric midline. Passing to the diagonal line of the "additional layer" in this case are not solid, but as in the previous embodiment, are interrupted in their intersections with the lines "base layer", like space stations.

On figa fine structure, which is superimposed on the line, reproducing the image of the shoulder 1 person, educated white-space plots, the contours of which have the form of a simple, but different geometric shapes as circles and short strokes. All whitespace plots on the same line have the same form simple geometric shapes, but each of the consecutive lines, the shape space of sections is different from the shape space areas provided on the neighboring line.

On figb in linear structures, the playback image is giving leverage of 1 person, made of reversible patterns, which in a series of consecutive lines alternately reproduced reverse images of numbers consisting of several numbers and letters, which partially form the words. In addition to fehb as an example of other possible combinations of linear structures "base layer" linear structures "additional layer" to some linear structures, reproducing the image of the collar, imposed a variety of small patterns. Thus, in particular, the image of the middle part 2 of the collar on the line superimposed made in the form of a negative image, i.e. whitespace, medium lines. In the image the left side 3 of the collar on the line superimposed fine structure consisting of spaced apart whitespace sites with simple, longitudinally elongated geometric shape.

Shown in Fig.7. variation of fine structure is also formed whitespace patches on the sealed lines, reproducing in this embodiment, composed of the letters "G" and "D" logo in the form of a negative image. The logo is repeated at regular intervals along the length of the lines, which are superimposed fine structure.

On figa on horizontal lines, reproducing the image of the right shoulder 1 made small structure, the play is handled the same logo, as figure 7. However, in the shown figa version of the logo is reproduced in the form of a positive image, i.e. the logo is reproduced in printed structures located on unsealed background. In the corresponding line of the base layer, on which is superimposed fine structure is almost completely absent, and it remains only a narrow, limiting it to the edges of the path. In this case, the logo is located exactly at the geometric middle line and is repeated several times along it. Instead shown figa image there is also the opportunity to completely "hide" the line, which imposed the fine structure, and to define its contours, reflecting the shape of its edges, signs or symbols, sizes, and under certain conditions, the thickness of the strokes which vary in accordance with the width of such "hidden" lines. Said illustrated by figb. This drawing shows another fragment of hand-drawn prints, different from those shown in previous drawings. In this drawing, on an enlarged scale showing a fragment of the person depicted in the portrait of the man, including his left eye and hair. One of the lines, reproducing the image of hair, respectively, of the lock of hair is made is not continuous, but is equipped with an overlay of fine structure. is such a small structure composed of capital letters, made in the form of a positive image and together forming the word "GUTENBERG". The location and size of, respectively, the height of these letters, consistent with the form and the outer contour or outline of the original line, reproducing the image of the strands of hair. In addition to the group of letters after it is made extremely thin, oriented transverse to the strands of hair curved line, podrazdeleniye line, reproducing the image of hair, on a separate, shorter line segments.

The present invention is not limited to the above versions run fine structures on its proposed data carriers. In principle according to the present invention there may be any variation and combination of fine structures of various types and kinds.

Figure 9 schematically and on an enlarged scale showing various embodiments of the mutually intersecting lines as an example of elements of a linear structures. Shown in figa image corresponds to the prior art, according to which both lines printed solid. On fehb and 9b where the lines have a different design. Thus, in particular, in the shown figb variant fine structure is formed due to the fact that the intersection of the two lines, only one of them made continuous or continuous, and the other line is in this place it per the section with a solid line break and left not sealed on this part of the gap.
