The objective of the invention is the provision of decalogo paintings mentioned at the beginning of the form, which can be dealt with well-known disadvantages and by means of which it can be sealed using metallographic printing secured documents deposited film element under gentle conditions for film elements.

According to the invention this is achieved by the fact that the printable area is the second area, which is made as a receiving element for at least one second segment of the optically variable element, in particular a film with an optical effect, or paint with an optical effect, the protected element, and the second region includes a number of receiving elements that are arranged in the raster. As a consequence obtained the advantage that it is only a slight change of the surface structure of the film element, and gloss properties of thin film element largely preserved. Due to the second area, it is possible to achieve a smaller partial pressure, thereby substantially avoid damage to part of the protected document that came into contact with vtoro the area. In addition, through the second region of the other elements can essentially be maintained surface structure. It turned out to be favorable, particularly for optically variable elements, and in addition to the film with an optical effect, can be provided, for example, also paint with an optical effect. Optically variable element can be located on the exposed print side or the opposite side. In particular, both sides of the protected document can also contain metallographic printing.

Consequently, it can be ensured that the quality of the optically variable element during the printing process essentially does not deteriorate, and optically variable element can be applied before the step of printing using decalogo paintings. This also can be provided by the sealing part of the optically variable element. According to another variant implementation of the invention can be provided that between the first area and the second area was formed essentially continuous (smooth) transition, resulting in largely avoid abrupt changes of load upon the protecting element during the printing process, which may lead to damage a protected document.

The invention relates to a method of sealing a protected document is and by metallographic printing, moreover, the protected document has at least one optically variable element, in particular a film with an optical effect or paint with an optical effect, and the opposite plate cylinder is a printing cylinder with dekalim blade with at least one first region with a first roughness.

The next task of the invention is the representation of a method of the aforementioned type, which avoids the known disadvantages and which can be sealed protected documents deposited film element by means of metallographic printing at moderate conditions for film elements.

According to the invention this is achieved by the fact that during the printing process of the optically variable element lead, at least in certain areas in contact with the second region decalogo paintings, and the second area is pre-defined with respect to the first roughness less significant second roughness and/or pre-set recess, and/or a pre-set lower than the first modulus of elasticity.

As a consequence obtained the advantage that it is only a slight change in the structure of the surface of the optically variable element, and the optical properties of Eremenko element largely preserved. Due to the second area, it is possible to achieve a smaller partial pressure, thereby substantially avoid damage came in contact with the second region part of the protected document, in particular an optically variable element. Optically variable element can be located on the exposed print side or the opposite side. In particular, both sides of the protected document can also contain metallographic printing.

In another embodiment, the invention can be provided that after the application of the optically variable element on a protected document on the opposite optically variable element side of the protected document carry out the print by means of metallographic printing, resulting in optically variable element can be applied, in particular, in paper production, and can optionally be at least partially into the paper.

The improvement of the invention can be provided that the optically variable element in a pre-specified first sector lead in contact with the first region, and the preset second site with the second region. In the first area is different from the second segment of the surface structure of the optically variable element which may be formed of another protective feature.

The invention is described in detail with reference to the attached drawings, which represent variants of execution.

Figure 1 is a top view of a variant of implementation of the relevant invention decalogo paintings; and

figure 2 - schematic side view of the plate cylinder, the printing cylinder and the protected document.

Figure 1 shows an embodiment corresponding to the invention decalogo cloth 1 for metallographic printing. When metallographic printing, which is also known as intaglio printing, with steel engravings, working with high clamping effort, which involves tactile impression, which is not achieved by other conventional printing methods. This tactile effect is a protective sign, so metallographic printing is used, as a rule, when printing is protected from falsification of documents 4, such as banknotes, bonds, certificates or other figure 2 schematically shows the system of the plate cylinder 3, the printing cylinder 2 with dekalim blade 1 and the protected document 4. Based on the high pressing force protected document 4 in the printing process is unrolled and change its value. Approximately uniform on the magnitude of the change together with the fact that compliance with pre-defined tolerances can be achieved by applying decalogo floor is TNA 1 with a rough surface, moreover, the structure decalogo cloth 1 is subjected to the embossing on the side opposite supplied with the print side of the protected document 4. Application decalogo cloth 1 with a smooth surface leads to invalid offsets register, so in the circle of specialists there is an agreement against the use of such decalogo canvas 1.

Decline cloth 1 has at least one first region 11 with the first surface roughness, and this is the first roughness ensures compliance with pre-specified tolerance. Therefore, the first region 11 has a rough surface. Presented in figure 1 decline cloth 1 is connected to the first region 11. In other embodiments, the first region 11 may include also separated from each partial region.

In addition, at least one second region 12, and the second area 12 is different from the first region 11 and the surface quality. Due to this different quality of the surface reach different compared to the first area 11 of the fingerprint decalogo cloth 1 on a protected document 4. The second region 12 can have, in particular, pre-defined with respect to the first roughness less significant second roughness and/or pre-defined recess 15 and/or pre-setting is emy respect to the first area 11 a lower modulus of elasticity. The second region 12 with respect to the first region is greater than the manufacturing tolerances of size, and, in particular, differences in the quality of the surface produced consciously and are preset. In figure 2 the second region 12 has a recess 15 on the first region 11. Such an embodiment was chosen on the basis of a simple image.

The second region 12 can be formed already during the production decalogo cloth 1 or on the next working step by partially changing the surface. If the second region 12 has a smaller surface roughness, in particular, if it is formed with an essentially smooth surface, the second region 12 can be made through the partial cold vulcanization printed canvases 1 with a rough surface. In addition, the surface decalogo cloth 1 can be changed by imprinting, and may include ordinary methods of printing, in particular screen printing. In other variants may be envisaged tab adhesive films or laminates for the formation of the second region 12. In addition, there may be provided a combination of the above-described processing methods decalogo cloth 1 with a rough surface to form the second region 12. For high SRO is and service decalogo cloth 1 second surface 12 should have a temperature resistance of up to about 80°C, high stability under pressure and high resistance to stretch.

The second area 12 may be provided for interacting with the optically variable element 5, in particular a film with an optical effect or paint with an optical effect, a protected document 4 during the printing process. This can effectively be prevented embossing patterns of the first surface region 11 on the optically variable element 5, and due to the differing quality of the surface of the second region 12 can be largely avoided changes optically variable element 5.

Between the first region 11 and second region 12 can be formed essentially continuous (smooth) transition. Consequently, it may be possible to largely eliminate abrupt load changes protecting element during the printing process, which may lead to damage a protected document.

During the printing process of the optically variable element 5, at least in some areas lead into contact with the second region 12 decalogo cloth 1. When this optically variable element 5 is carried out through the gap between the plate cylinder 3 and the printing cylinder 2. Optically variable element 5 can be located on the side adjacent to the printing cylinder, or premikudu is to the plate cylinder 3 side protected document 4.

In this way, in which you can avoid unintentional changes of the optically variable element, possibly after applying optically variable element 5 on the protected document 4 to print on both sides of the protected document 4 by means of metallographic printing. Thus, in particular, metallographic printing can in certain areas to block the optically variable element 5, as a result achieve the high reliability of the protected document.

Can also be provided that the optically variable element 5 in a pre-defined first area 51 is brought into contact with the first region 11 and the second pre-defined area 52 with the second region 12. Consequently, the optically variable element 5 during the printing process is changed in the first area 51, but remains essentially unchanged on the second site. This difference optically variable element 5 is another protective feature. The first section and the second section can be performed, for example, sculptured or with the education code.

The second region 12 is located in the printable area, and the printed area is the area in which the protected document 4 print during the printing process. The second region 12 can be formed as a receiving element, at least the second leg 52 is pricheski variable element 5, in particular film with an optical effect or paint with an optical effect, a protected document 4. In particular, if the printing process simultaneously print multiple secure document 4, the second region 12 may include several such receiving elements that are arranged in a raster.
