Definitions
- the invention relates to a sheet-fed or roll multicolor rotary printing machine, in particular for printing the security background on securities, especially banknotes, according to the preamble of patent claim 1.
- Such a printing machine for producing a multi-color print is known from FR-A-2.222.214.
- This multicolor print is an offset or indirect letterpress, which provides an image with overlaid colors and patterns and is often used to print the security background on securities.
- a combined printing press is described, the first printing unit of which is the offset printing unit, which is followed by a steel engraving printing unit as the second printing unit.
- the group of two cylinders mentioned in the preamble of claim 1 belongs to the steel engraving printing unit and consists of the plate cylinder carrying the engraving printing plates and the impression cylinder.
- the complete printing pattern is composed of differently colored partial patterns: each partial pattern of a certain color is represented by a printing plate, which is arranged on a plate cylinder. This creates a register-based overlay of the different colors and patterns.
- the number of printing plates and consequently of the plate cylinders corresponds to the number of differently colored sub-patterns which form the complete multicolored image.
- a convertible printing machine is known from US-A-2 659 305, which can be used for printing in steel engraving, high-pressure or offset printing.
- a master cylinder interacting with an impression cylinder is equipped with engraving plates: as inking rollers for the engraving plates are used as stencil rollers, and a wiper device with a wiper cylinder and a further ink-taking cylinder made of metal working together with the wiper cylinder is brought into the operating position.
- the engraving pressure plates on the master cylinder are replaced by high pressure plates, and the wiper device is brought into an out-of-operation position.
- the master cylinder is covered with a rubber blanket after the printing plates have been removed, and the stencil rollers are replaced by plate cylinders.
- the paper is printed in the same printing gap between the master cylinder and the impression cylinder, and the way of inking is the same, in that the colors from the inking rollers or the plate cylinders replacing them pass onto the paper via the master cylinder.
- a convertible printing machine is known from DE-A-1 152 704, which can be used either for direct letterpress printing or for offset printing. It comprises a plate cylinder, the printing plates of which are inked by several application rollers, a printing cylinder interacting with this plate cylinder, a transfer cylinder interacting with this printing cylinder and an adjustable sheet transfer drum, which transfers the paper to the printing cylinder, which then functions as a counter-pressure cylinder, and to the transfer cylinder in offset printing .
- the paper passes the printing gap between the plate cylinder and the printing cylinder
- the printing gap between the printing cylinder which is then colored by the plate cylinder and acts as a rubber cylinder, and the transfer cylinder.
- the directions of rotation of all cylinders with the exception of the sheet transfer drum, must be reversed and the path of the paper through the machine must also be changed.
- the invention has for its object to provide a rotary printing press with which optionally an image with superimposed colors and print patterns after.
- Offset printing process by means of several printing plates, the number of which corresponds to the number of different-colored printing patterns to be printed, or an image with adjacent colors according to the batch printing or "Orlof" process, by means of a single high-pressure plate having the pattern to be printed in full and several stencil rollers, the number of which Corresponds to the number of colors to be printed, can be produced and which enables the transition from one printing process to the other in a simple manner.
- the main advantage of the printing machine according to the invention is not only of a technical nature, since it enables two completely different printing methods, but also of an economic nature, because it offers the user the choice of the printing method without having to use two separate machines.
- the security background of banknotes can be produced either as offset printing or as "Orlof" printing.
- a multi-color image is obtained on the high-pressure plate, which has the complete image pattern and is colored in multicolor by the first rubber cylinder, which acts as a collecting cylinder, on which the register between the different colors of the Image pattern is perfect; such a result can practically not be achieved with any other printing method.
- the printing press has a known sheet feed device 1, which has a scale feeder (not shown), a stop drum 2, a transfer drum 3 and a paper dedusting and antistatic device 5.
- a sheet edge numbering unit 4 can optionally be provided.
- the sheets reach an impression cylinder 6, which rotates in the direction of the arrow, and after printing by a chain gripper system 20 are transported to a sheet delivery or to another printing machine for printing on the other side of the sheet.
- the sheets on the impression cylinder 6 can be printed according to the invention either by the "" Orlof "method ( Figure 1) or in indirect letterpress or offset printing ( Figure 2), preferably to produce a multi-colored security background on one side of a
- the printing press has a rubber cylinder 7 which is used in both cases, but in different ways.
- the impression cylinder 6 has moved away from the blanket cylinder 7 (FIG. 1).
- a shift of the impression cylinder 6 from the blanket cylinder 7 can be easily achieved with the aid of an eccentric 6b, on which the body of the impression cylinder 6 is mounted.
- Such assembly with the aid of an eccentric is known for adjusting the contact pressure and for turning off two cylinders that are not in operation; when the eccentric is turned, the axis of the cylinder in question shifts accordingly.
- Known means can therefore be used for this disengagement in existing machines. If the two cylinders are separate, the distance between them is very small, generally only one or more millimeters; the distance shown in Figure 1 is greatly exaggerated.
- the rubber cylinder 7 interacts with four stencil rollers 8 which have sector-like relief-like elevations 8a corresponding to the contour of the zones to be printed in the relevant color; each of these elevations 8a is in turn inked by an inking unit 9 assigned to the relevant stencil roller 8.
- These stencil rollers 8 with their ink-accepting elevations 8a are preferably made of a hard material which does not deform even in the case of very finely cut reliefs, so that a security base can be produced from very fine lines.
- the zones of the four colors corresponding to the contours of the elevations 8a are transferred to the rubber cylinder 7, which functions as a collecting cylinder which combines these color zones next to one another and transfers them to the printing plate 10a of a single plate cylinder 10.
- This printing plate 10a is a high-pressure plate and has the complete pattern to be printed in four colors.
- the complete image, colored in the different colors, is in turn transferred to a rubber cylinder 11, which has a smaller diameter than the rubber cylinder 7 and cooperates with the impression cylinder 6 in order to print the complete image on the paper.
- the machine also has two ink transfer cylinders 12 and 13 in contact, which transfer the same image of the ink zones located on the blanket cylinder 7 from this blanket cylinder 7 to the plate cylinder 10 in register, thereby intensifying the inking of the printing plate 10a and consequently these zones the colors in question are better covered.
- the majority of the colors are first transferred directly to the printing plate 10a of the plate cylinder 10, while the remaining color is then transferred in register by means of the ink transfer cylinders 12 and 13.
- the dampening offset system has a plate cylinder 14 carrying an intaglio printing plate, an inking unit 15 and a dampening unit 16 known per se, the intaglio printing cylinder 14 cooperating with a rubber cylinder 17 which transfers the image onto the paper.
- a complete print on a banknote page in a single printing process namely the four-color security background by printing according to the "Orlof” process and the single-color main pattern by one Wet offset printing.
- the ratio of the diameters of the cylinders 8, 10, 11, 12, 13, 14 and 17 on the one hand and the cylinders 6 and 7 on the other hand is 1: 3; the circumference of the cylinders 6 and 7 thus corresponds to the dimensions of three sheets of paper, and accordingly the blanket cylinder 7 and the impression cylinder 6 are each covered with three blankets 7a and 6a, while the blanket cylinder 11 and the ink transfer cylinders 12 and 13 each have only one blanket 11a, Wear 12a or 13a.
- the printing on the paper takes place directly through the plate cylinder 10, whereby the printing plate 10a is colored by the rubber cylinder 11, which in turn is in contact with both the rubber cylinder 7 and the transfer cylinder 13.
- the printing plates 8b are high-pressure plates, as are used in dry offset printing, and have partial patterns which, as in the previous case, are colored by inking units 9. These differently colored partial patterns are combined in register on the rubber cylinder 7, which in this case functions as a collecting cylinder for the partial patterns forming the multicolored overall image.
- the adjustment of the distance between the different cylinders, i.e. between the impression cylinder 6 and the blanket cylinder 7, between the blanket cylinder 11 and the impression cylinder-6, between the cylinders 10 and 12 and the blanket cylinder 7, and the required displacements of the other cylinders interacting with these cylinders can be achieved by known adjusting means, in particular by mounting all cylinders on eccentric bushes, as already mentioned for the impression cylinder 6.
- the distances between non-interacting cylinders are very small and generally only a few millimeters in size.
- the plate cylinder 10, the blanket cylinder 11 and the ink transfer cylinders 12 and 13 are not used and are therefore stopped by decoupling from the drive system of the machine.
- damp offset system can be dispensed with in the context of the invention, but, as mentioned, this system allows a complete print to be obtained on one side of a security.
- the stencil rollers 8, 8a which are intended for inking the blanket cylinder 7 when printing according to the "Orlof" method, can be replaced by inking stencils or by color contour plates which can be attached to the actual rollers or cylinders.
