The invention relates to a printing machine for printing securities, in particular Bank notes, sheet and roll paper, comprising the main printing apparatus.

In modern technology, these machines are known. For example, in European patent application 0132858 described machine, you can print on front and back side of the paper multicolor image by various printing methods, in particular way, usually called "orlof-offset, and offset. When printing method "offset-offset" on both Stour is be full figure consists of partial images of different colors, done with the help of printing clichés that are installed on the outer cylinders, which allows in turn to put the pictures and color register at offset cylinder, which then presses the print paper. The number of printing plates and, accordingly, the plate cylinder is equal to the number of different colors and images that constitute the multi-color image printed products. When using the machine for odnoprovodnoi duplex multicolor image is applied to the two offset cylinders, between which then passed the printing paper for applying images.

This machine has some disadvantages, such as limited number of color combinations because of the size of the offset cylinder and the volume occupied colorful devices.

Another printing machine of this type is described in patent application 0343105. This printing machine is used for multicolor odnoprovodnoi double-sided printing method, called popularly "orlof-offset". In this way the paint is applied on cottonbelly cylinder with a few tsvetodelenie cylinders, the number of which is equal to the number of different colors that make up this image. N is the population painted in this color. Printed on cottonbelly the cylinder through tsvetodelenie cylinder to transfer the image then through the plate cylinder of an offset cylinder, which eventually causes it to paper. To implement odnoprovodnoi print on the front and back sides of the paper, respectively, are two of tsvetonosnyh cylinder, one for each side of the paper with their tsvetodelenie cylinders and two offset cylinders, between which is skipped printed paper. In known methods each front or back imprint may contain up to four different colors. This known machine comprises, in addition, additional inking unit for one or the other offset cylinder or two at the same time for applying additional paint on one or the other side of the paper, increases the degree of protection of printed securities. This additional inking unit includes, in particular, of the plate cylinder, similar to the plate cylinder used in the Orel-offset printing technique that transfers ink of a given color from zotenberg cylinder of the offset cylinder. This additional colorful hardware cylinders.

The disadvantage of such machines is that the number of printing capabilities, in particular the number of desired colors, is also limited by the dimensions of the blanket cylinders and the volume occupied colorful devices. In addition, the use of standard offset cylinder limits of various types of printing that can be used for additional or complementary colors.

The aim of the present invention is to improve machines are already known in printing technology.

More private object of the present invention is to provide a printing machine, which can increase the possibility of printing of securities on the sheet or roll paper to ensure the best security and diversify the possibilities of using various types of multicolor printing. When this fake securities becomes more difficult and will require rigged attachments much more funds.

In accordance with the present invention, the printing machine differs in that it includes additional printing apparatus, installed in front of the main printing apparatus according to the direction of movement of the paper and allows to apply across the entire width of the paper ornament, IU the s paragraphs 2-11 claims defined private ways of implementing the present invention.

With additional printing can be applied to various known types of printing, in particular offset printing, screen printing or heliography.

In the most preferred embodiment of the invention additional printing apparatus used for printing protective elements.

In addition, additional printing apparatus, it is preferable to set the drying unit, for example, from UV radiation.

This new machine has many advantages: in particular, additional printing apparatus made according to the type of the removable module and can be installed easily into existing printing machine. In addition, the method of printing used to print the apparatus is not limited to the method used in the existing printing machine as it is considered to be in a known technology, and allows you to create new combinations of printing methods. The diversity of types and methods of printing will complicate the task of potential falsifiers.

Another advantage of the present invention is that, in addition to the possibility of combining different types of printing and increase the number of colors, it has allowed the major machines. Thus, in one continuous passing of the paper printing of securities with a high degree of protection becomes easy and efficient. In addition, it is possible to vary the types of inks for printing securities, since it is possible to use several different methods of printing.

In this technical field, there was a prejudice against the setting above for more of the printing apparatus in the known machines. It was considered impossible to carry out a preliminary application of the imprint on the paper prior to its passage through the main printing apparatus, since the paint with pre-applied additional imprint could go to the main cylinders of the printing apparatus. On the other hand, the implementation of such a system seemed difficult and, as a result, unprofitable. In fact, as it turned out, this problem is solved relatively easily, and due to the drying of the paint does not come with a paper on the main cylinders of the printing apparatus.

The essence of the present invention becomes apparent from the description of one of the variants of its implementation with reference to the accompanying drawing, which shows a side view in partial section of the printing machine, mainly p is integral print.

In the classical form of machine 1 for odnoprovodnoi double-sided offset printing has a main printing apparatus comprising two offset cylinders 2, 3, rotating in the direction of the arrows, between which passes the paper on which applied multicolor prints. Different patterns of the respective colors are applied to offset cylinders 2, 3 by means of the plate cylinders 4-11, distributed around the surface of the aforementioned blanket cylinders 2, 3. On the plate cylinder 4-11 with relief blocks the usual well-known in the technology in the way the paint is applied by means of the inking units 12 and 13, respectively.

Additional printing apparatus has a common designation 20 and installed before the offset cylinders 2, 3 in the direction of movement of the paper in the machine. As indicated above, additional printing apparatus is set to apply a variety of classic types of printing, in particular offset printing, screen printing and heliography. In the above example, we are talking about the device two-color offset printing, comprising printing cylinder 21, the offset cylinder 22, two of the plate cylinder 23 and 24 and the two classic colourful apparatus 25 and 26. With the help of rollers of the inking units 25 is the position then transferred in exact correspondence to the offset cylinder 22, and the full image is printed on paper that passes between the blanket cylinder 22 and the printing cylinder 21 due to the pressure of the printing cylinder to the offset cylinder.

The ratio between the diameter of the printing cylinder 21 and the diameter of one of the blanket cylinders 2 or 3 of the main printing apparatus is set to about 2/3. This attitude corresponds to two conflicting conditions, i.e. the diameter of the printing cylinder 21 is large enough to handle the complete drying of additional imprint using the required number of lamps, and at the same time small enough to be installed in the printing machine.

Describes the advanced printing apparatus thus allows to add two ornaments of different colors on the paper by means of the plate cylinders 23 and 24.

Before passing between the blanket cylinders 2, 3 for the continuation of the printing process, paper is still passed through the drying unit formed by, for example, lamps 27, 28 ultraviolet radiation located around the printing cylinder 21. This unit dries the newly applied paint, which is not mixed with paint damage to the main printing apparatus.

Printing machine according isoboard the printing apparatus 20 and the offset cylinder 2 main printing apparatus 1.

Given that the use of additional printing equipment allows you to apply various methods of printing, it can print at the same time a part of the protective background or part of the principal ornament of the securities.

The present invention is not limited to the described manner, and within the requested legal protection possible other options for its implementation. For example, on one side of the paper can be applied only one additional color or apply one color on each side of the paper. In addition, such additional printing apparatus can be installed in a printing machine, mainly printing apparatus which uses, in addition to the above offset printing, other printing methods such as gravure printing, orlof-offset printing, orlof-gravure printing or printing using different optically variable elements.
