    The invention relates to the printing industry, in particular to multi-color rotary printing machines for duplex printing in a single pass.
    The purpose of the invention is the expansion of technological capabilities.
    Figure 1 is a schematic diagram of a printing press; Fig, 2 is the same, with a wet offset printing unit.
    The machine contains the first and second 2 offset cylinders, which are in contact with each other to provide printed contact, in contact with the first offset cylinder 1, a group of plate offset cylinders 3-6, corresponding to their colorful machines 7-10, the third cylinder 11, in contact with color separation cylinders 12 - 15, and the corresponding colorful devices 16-19.
    The device also has a plate cylinder 20 with a letterpress printing form in contact with the third cylinder.
    11 and the second offset cylinder 2, while the third cylinder 11 is filled with offset and is located with a gap relative to the second offset cylinder 2, and the color separation cylinders
    12-15 are made of rigid material.
    At least m, one of the offset printing cylinders 6 carries the wet offset printing form and wetting agent 21, the other printing offset cylinders 3-5 have the shapes for dry offset printing. The machine contains an offset printing unit, predominantly wet offset printing, with a printing cylinder 22 in contact with the second offset cylinder 2.
    The proposed machine is a sheet-fed machine and comprises a paper input device in the form of sheets 23, equipped with a feed-cylinder 24, two transfer cylinders 25 provided with grippers, and devices 26 and 27 for removing dust and eliminating static electricity placed respectively on the sides of the paper. 23. Sheets 23 are transmitted to a blanket cylinder 1 provided with grippers and in contact with an offset cylinder, 2 of the same diameter, which passes between the blanket cylinders 1 and 2 and is produced simultaneously on both sides of them. print. The cylinders rotate in the direction indicated by the arrows. After printing, sheets are transported by the -28 chaining system to stacks or, if necessary, to another machine to complete printing. The machine has a main engine 29.
    According to figure 1 offset cylinder 1 interacts with four plate cylinders 3-6, each of the three cylinders 3-5 is equipped with an offset plate plate, on which the colorful device 7-9 causes coloring. The fourth shape cylinder 6 carries a wet printing offset plate, on which the ink is applied with the colorful agent 10 with a single color tray equipped with a dampening device 21. The elements 6-9 are placed on the movable carriage 30.
    Plates for dry offset printing are printing plates of a known type, and a plate for wet offset printing is a deep etching plate of a known type. On four plates there are partial patterns covered with ink of different colors, the number of which corresponds to the number of colors and patterns of the first printed image on one side of the paper 23. In particular, such an image can be a protective grid of bank notes and paper money.
    Private images of different colors are combined on cylinder 1, acting as an offset or collecting cylinder of private images forming a multi-color image. The resulting image is transferred to one side of the paper, in this case, the reverse, where a dry three-color offset imprint is obtained, supplemented with a wet offset monochrome print.
    In the case of monetary documents, it is also possible to use three inlet cylinders 3-5 for dry offset printing to create a tricolor background, while the formin cylinder for wet offset printing 6 provides the main pattern.
    For offset printing, all of the forme cylinders are mounted on the movable carriage 30, and can be equipped with plates for dry offset printing.
    on the other side of the machine there are elements for implementing the eagles method. They include an offset cylinder 11 of the same diameter as the offset cylinders 1 and 2. In this case, the offset cylinder 11 interacts with four color separating cylinders 12-15, on which the contour of the printed zones of the corresponding color is etched. Each of them is painted with paint a. Paraty 16 - 19 with a double colorful trough. All elements are placed on a movable carriage 31 for applying paint according to the Eagles method. Cylinders 12-15 are preferably made of a durable material that does not endanger the deformation even with very thin reliefs, which allows to obtain a protective grid consisting of very thin color zones. The four-color zones are transferred to the offset cylinder 1.1, acting as a collecting cylinder, on which the colors are combined and from where they are transferred to the plate cylinder 20, carrying a printing plate in contact with said collecting cylinder and with the offset cylinder 2.
    The printing plate is a complete drawing of the second image printed in four colors on the other side of the paper. The full colorful image is transferred to the blanket cylinder 2 for printing the finished image and, in particular, the protective mesh on the front side, and the offset image is simultaneously applied to the reverse side. During simultaneous printing, cylinders 1 and 2 serve mutually: backpressure cylinders.
    In addition, the machine contains the first 32 and second 33 image transfer cylinders, which transfer the same image to the colorful zones of the offset cylinder 11 with an excellent cast on the typographic plate cylinder 20, which makes it possible to enhance the application of paint of the desired colors on the printing plate and thereby It is better to coat the zones with the desired paint. In the projection in the direction of rotation of the offset cylinder 11, part of the ink is transferred by cylinders 32 and 33 to the typographic printing cylinder 20, and the remainder is colored 40576
    The ki is transferred with excellent registering directly to cylinder 20.
    The design of the double ink application cylinders is known, the second ink application is offset along the periphery of the typographic printing cylinder 20, or in this case, one third of the periphery of the offset cylinder, Q pa 11, since its diameter is three times the diameter of the cylinder 20 and it carries three offset webs.
    To fulfill the condition of registering the design of cylinders 11, 32,33 and 20 15 is chosen such that the sum of the lengths of arcs on the periphery of cylinders 32, 33 and 20 between the corresponding contact points in the projection B, the direction of rotation of these cylinders must be equal to Q the length of the arc on the periphery of the cylinder 11
    between the points of its contact with the cylinder. 32 and 20 plus 1/3 from the periphery of the cylinder 11.
    If the drawing is printed on a type 25. graph printing plate according to
    The Eagles method, consists only of lines and the paint zones are very narrow, it is possible to refuse cylinders 32 and 33 of the image transfer and 0 to be limited to applying ink to the printing plate once.
    In this case, the ratio of the diameters of the cylinders 3 - 6, 12 - 15, 32, 33 and 20 and the cylinders 1,2 and 11 is 1: 3. The periphery of cylinders 1,2 and 11 corresponds to three sheets of paper and each cylinder carries three blankets.
    In the embodiment of the construction of FIG. 2, the printing according to the Eagles method is supplemented with one color of wet offset printing performed by the passage of paper between offset cylinders 1 and 2, which serves to print the main mono-5 chrome image of the value of the valuable paper. The wet offset printing node contains a plate cylinder 22 provided with an inking machine 34 and a means 35 for moistening the shape of a known structure, the plate cylinder 22 interacting with the offset cylinder 2 transferring the image onto the paper. In this case, in a single pass, a full g imprint is obtained on the front side, for example, a four-color protective grid, using the Orlov printing method, as well as a main monogram pattern by wet offset printing, and on the reverse side of the paper, a four-colored protective grid is obtained. printing, or a three-color grid and the main monochrome drawing, using wet offset printing,
    The proposed printing machine can easily be used as a roll printing machine simply by replacing the sheet transport means with the means for transporting the paper strip passing between the offset cylinders 1 and 2.
