Definitions
- the invention relates to a value and / or security document, comprising a monolithic document body, which is assembled from a plurality of substrate layers, wherein on at least one of the substrate layers printing technology a security print pattern is applied as a security feature comprising a fine line pattern.
- the invention further relates to a method for producing such a value and / or security document.
- Security and / or security documents include passports, identity cards, identification cards, access authorization cards, credit cards, debit cards, telephone cards, banknotes, driver's licenses, etc.
- One group of these security and value documents comprises a monolithic document body made of a plurality of plastic layers. These are preferably joined together by a lamination process to form a monolithic body.
- Security and / or security documents contain individualizing and / or personalizing and / or other identifying information that enables the value and / or security document to be assigned to a value, object and / or person and / or group of persons.
- a credit card contains information about a credit card account and an account holder, as well as the account-holding bank. The credit card makes it possible for the assigned user to initiate payments to third parties from the corresponding account by the bank.
- An identification document such as a passport or identity card, includes personal information about an associated user and information indicating an issuer, such as a state, of the identification document. The identification document may use the assigned person to identify himself.
- One group of security features includes printing by applying a security print pattern.
- Security print patterns are considered to be patterns which are designed in such a way that imitation and / or falsification by an unauthorized body is only difficult or preferably impossible.
- a group of security prints includes a fine line pattern.
- Such fine line patterns are used classically, in particular in the case of printing equipment for identification documents, securities and banknotes.
- the fine lines are often used in such a high line density per area that they are initially perceived by a viewer who views the value and / or security document not as individual lines, but as an area with a texture or a color value. For example, a brightness and / or intensity with which a hue is perceived depends on a number of lines per area.

- Substrate layers of Figures 9a and 9b is prepared and in which an individualizing and / or personalizing information about a shape of the fine line is encoded.
- Fig. 9d is a sectional view of the security document of Fig. 9c.
- FIG. 1 shows a schematic plan view of a security document 1.
- the security document 1 has a security printing pattern 2 applied by printing technology. This includes a fine line pattern 3.
- the illustrated fine line pattern 3 comprises two intertwined fine lines 4, 5.
- Such a protective line work made of fine lines is also called a guilloche pattern.
- the lines of a guilloche pattern are called guilloche lines or short guilloches.
- the fine lines 4 and 5 thus represent guilloches.
- the guilloches are formed according to certain geometric laws. Nevertheless, these geometric laws from a guilloche pattern are usually not directly derivable. Therefore, imitation and replication of the guilloche pattern is difficult.
- the individual guilloches or fine lines 4, 5 are frequently printed in such a way that they are alternately printed along their course between two different shades, wherein a transition from one hue to the other hue and vice versa is formed by means of a continuous color transition.
- fine line is used, which should, however, include the term guilloche.
- the security document 1 may include a variety of other security features which are not shown here for the sake of simplicity.
- the security document may comprise a serial number and / or additional individualizing and / or personalizing information in a non-coded and / or coded manner.

- the two print separations according to FIGS. 2b and 2c are printed on one or more substrate layers by means of different printing methods, which are then preferably to a monolithic document body of the value and / or security document via a lamination.
- a printing process for example a wet-offset printing process, a waterless offset printing process or a direct and indirect high-pressure process.
- the printing method is chosen so that it prints the line sections 6, 8 as continuous smooth contours or contour sections on the substrate.
- the second print separation of Fig. 2c is printed by another printing method which uses printing dots to form a printed image.
- Such a printing method is, for example, an inkjet printing method in which the individual nozzles of a print head are "pulsed".
- An assignment of the print separations 2b and 2c to the printing process is indicated by a representation of the line sections 6-8 respectively.
- the line segments are shown as solid lines, the corresponding printout printed by a printing process that can print continuous smooth contours as line sections. If the line segment is shown in dotted lines, this indicates that the corresponding print separation is being printed by means of a printing process which forcibly uses printing dots during printing. This convention is observed in all figures of this application.
- the two print separations are printed in such a way that they complement each other in the finished security document in register with the contour of the fine line 4 according to FIG. 2a.

- the line sections 6, 6 ", ... have the color magenta
- the line sections 7, 7 ', ... have the color cyan, for example.
- the line has sharp color transitions between the colors magenta and cyan and vice versa, it is preferred to print a continuous color transition or a color gradient between these two colors or shades in each case.
- pressure extracts 9, 10 are similar to those shown in Fig. 3a and 3b, but in which the individual line sections 6, 6 ', ... and 7, 7', ... changed so formed, that these overlap each other in the printed image at their ends.
- a corresponding print image 11 is in
- Fig. 4c shown.
- the color in the center of the line sections 6, 6 1, the viewer perceives a is magenta.
- the second printing separation 10 which is printed by means of a printing method using printing dots, a cyan impression results for the observer.
- a transition from magenta to blue to cyan results, for example, from the line section 6 'to the line section T.
- the two printing extracts 9, 10 are printed on a substrate layer surface of a substrate in a short temporal sequence by means of the different printing methods, so that a mixture of the printing inks occurs.
- a printing dot size decreases. This ensures that an area proportion of that hue with which the corresponding line section or the associated print separation is printed decreases.
- the ends 14, 15 of the line sections 6, 7 are matched to one another such that a decrease in a color area portion of a line section corresponds to an increase of a color area section of the other line section. This makes it possible to achieve a particularly uniform color transition between the different shades.
