Description

The present invention relates to a printing form apparatus and a printing unit for the application of identification marks on a substrate. Furthermore, the invention also relates to a method for positionally accurate printing of an identification mark on the substrate. The printing material may, in particular, be a preliminary product (blank) of a security document, for example a banknote, a check or another security.

Banknotes, checks and other securities issued in larger quantities are usually numbered to ensure clear identification of each individual piece. In the case of banknotes, the numbering may further include information about the issuing body, the printing office or the position of the banknote on multiple use and the like. The identification numbers of a banknote are usually formed by a combination of letters and numbers. The same or similar may apply to other securities.

For the production of banknotes these are first printed on sheets from the special paper intended for their production and then separated. The banknotes are then collated into bundles, taking care to provide the banknotes within the bundles with consecutive numbers. The same generally applies to other securities, such as checks.

To provide the value or security documents with the identification numbers, the documents are generally initially completed, i. provided with all security features and imprints required for these documents. Subsequently, the respective identification numbers are printed on these preliminary products of the documents. These numbers can be printed on the document in different places and in different orientations. For example, EURO banknotes of the series 2 contain a respective assigned serial number on the back twice at different locations, the two number prints are arranged in mutually 90 ° orientation.

To generate these number prints, number works are used which generate the serial numbers on the banknotes. The numbering printed with these devices must be continuous on the banknotes. This means that the number printing changes from banknote to banknote by one number unit at a time. Suitable devices have been developed for this printing.

Out DE 20 2007 019 477 U1 shows an electromechanical banknote numbering device which has a numbering unit with rotatable numbering wheels which carry alphanumeric symbols, wherein the numbering wheels are arranged side by side and rotate about a common axis of rotation. The numbering device further comprises electromechanical actuators for adjusting the position of the numbering wheels. The electromechanical actuators are located entirely within the numbering device and are mechanically autonomous. They have a plurality of independent drive units for actuating a corresponding plurality of numbering wheels. A portion of the total numbering wheels may be actuated by independent drive means, and a remaining portion of the numbering wheels may be manually operable. Each drive device has at least one electric motor which drives the assigned numbering wheel via a gear arrangement, wherein the gear arrangement has a first reduction factor. The electric motor is a brushless DC motor with electronic commutation. Each electric motor is coupled via a reduction gear with the gear assembly. The reduction gear provides an additional reduction of the output speed of the electric motor to the gear assembly, wherein the reduction gear is a miniature planetary gear. The alphanumeric symbols on the numbering wheels are raised and reversed.

Out DE 60 2005 000 255 T2 In addition, a method for applying markings to security papers is known in which at least one composite identity mark is formed from a first identity mark and at least one second identity mark. The two marks are created by different marking stations, the second marking station being a laser marking station. For marking, an arc is created on which a basic design of the notes on fields of the sheet is printed identically and these fields correspond to the individual notes such that, after cutting the sheets into individual notes, stacks of consecutively numbered notes are formed. The numbering machine includes a pair of marking stations spaced on the outer circumference of a roll and spaced around the roll. For printing, the sheet is guided around the roller and thereby printed by means of the marking stations.

Using such numbering engines, it has been found that the identity marks are only partially generated within a given surface area, but in some cases are partially printed outside of that area on the surface. For example, when printing banknotes as multiple uses in sheetfed printing serial numbers are applied to these sheets. These are often not printed within the tolerance. This results in rejects of the corresponding banknote or the entire sheet, so that the faulty prints have to be reprinted separately. In addition, since there is a requirement to collate the banknotes into bundles after printing and separating by cutting the sheets in ascending or descending order of the serial numbers, a logistical problem arises because the missing rejects must be added in the correct position after one reprint in the bundle.

In the current production of euro banknotes no reprints are categorized, but the committee is destroyed without replacement. Reprinted banknotes are then provided with serial numbers that are attached to the serial numbers used.

The present invention is therefore based on the problem that the identification marks on a security or valuable document, for example a security surface, are not always generated at the intended location, so that an object of the present invention is to ensure that the identification marks always be generated within a given surface area.

In the description and in the claims of the present application features and elements in the singular are mentioned, for example 'identification mark', 'numeral', 'actuator', 'sensor', 'pressure field', 'transfer roller', 'counterpressure roller',, inking unit '' Compression Form ',' Identification Mark ',' Marking Field 'shall, at the relevant point below, also be understood to mean the corresponding feature or element in the plural, and vice versa, unless expressly stated otherwise.

In addition, the substrate can also be made of several of these materials, either by mixing the nonwoven fabrics and / or polymers together or by joining several layers of these materials together, for example by gluing, laminating, extruding or the like. The polymers may be either unfilled or filled. In the former case, they are preferably transparent or translucent. If the polymers are filled, they are opaque. The above information relates both to films to be bonded together and to liquid formulations applied to a precursor, such as a resist. The product is preferably prepared from 3 to 12, preferably 4 to 10, films. A laminate formed in this way can finally be coated on one or both sides with a protective lacquer.

Insofar as the term "value or security document" is used in the description and claims of the present application, this includes, for example, a passport, identity card, driving license or another ID card or access control card, a vehicle registration document, vehicle registration document, visa Customer card, health card, chip card, a company card, proof of eligibility, membership card, bill of lading or other proof of entitlement, a security, for example a check, means of payment, in particular a banknote, a check, bank, credit or cash card, a gift or purchase voucher, Control characters, postage stamps, tickets, tokens or an adhesive label (for example, for product security) or to understand another ID document.

According to a first aspect of the present invention, to solve the above-mentioned problem, a printing forme apparatus for created the application of identification marks on a substrate. This device has according to the invention at least one arranged on a rotatable support member numbering (Numerota), the position of which is adjustable on the rotatable support member, for example in the axial and / or radial direction.

According to a second aspect of the present invention, a printing unit is provided for applying identification markings to a printing substrate which has at least one printing form device according to the invention. The printing unit also has at least one transfer roller, at least one counter-pressure roller and at least one inking unit. The printing unit is designed so that the color originating from the at least one inking unit reaches the at least one printing forme device, from there to the at least one transfer roller and from there to the printing material.

• (b) Ermitteln der Position der mindestens einen Identifikationsmarkierung auf dem Bedruckstoff;
• (c) Vergleichen der ermittelten Position der mindestens einen Identifikationsmarkierung mit einer Sollposition; und
• (d) Verstellen der Position des mindestens einen Nummernwerkes auf dem rotierbaren Halteelement.

According to a third aspect of the present invention, a method is further provided for the positionally accurate printing of an identification mark on a printing substrate by means of a printing unit having at least one printing form device according to the invention. The printing forme device has at least one numbering unit on a rotatable holding element whose position on the rotatable holding element can be adjusted in the axial and / or radial direction. The method comprises the following method steps:

• (a) printing on the substrate with at least one identification mark;
• (b) determining the position of the at least one identification mark on the printing substrate;
• (c) comparing the determined position of the at least one identification mark with a desired position; and
• (D) adjusting the position of the at least one numbering works on the rotatable holding element.

It has been found that the printing material used for printing is stretched by the printing process by rolling transversely to the transport direction and in particular at the leading edge (top edge) of a printing material piece. A closer look reveals that, for example, printing material sheets are deformed trapezoidally by the delay, wherein the longer base side of the trapezoid forms the leading edge (in the transport direction in the printing press). As a result, the identification marks, for example serial numbers, are printed on banknotes, in particular in the corner regions of the sheets outside the tolerance, markings in the marginal areas being particularly affected by the trapezoid deformation. Particularly problematic is the printing of several 90 ° rotated against each other identification marks, since the tolerance for these printed along the direction of transport marks in this case is even lower. The adjustability of the individual numbering works minimizes waste in the production of value or security documents and reduces press downtimes for a fine adjustment of the numbering works, which has hitherto been carried out manually and for which the press is opened and the inking cart is lowered.

Furthermore, in particular a construction of the printing unit with the printing form devices according to the invention is critical if, for printing multiple-use sheets, a plurality of number works are provided in a matrix-like arrangement, i. in rows and columns on the shell of the printing form roller, which are in a column, i. in the direction of transport one behind the other, located numbering works are kept together and their position in the printing unit therefore could possibly be adjusted together at best. Since the deformation of the printing material, in particular in the edge region lying pressure areas on the substrate affects an adjustment to a desired position would succeed only for a single numbering of a column or only a few number of works.

The numbering units of the printing form devices according to the invention can, in particular, as in DE 20 2007 019 477 U1 be formed specified. Therefore, the disclosure content of this publication is incorporated herein by reference in its entirety, or at least to the extent that the structure and operation of the banknote numbering apparatus described therein are specified in this publication.

Thus, the printing form device according to the invention may in particular comprise one or more numbering works with rotatable numbering wheels which can carry alphanumeric symbols. The numbering wheels are arranged in a numbering next to each other and rotate about a common axis of rotation. The numbering machine may further comprise electromechanical actuators for adjusting the (rotary) position of the numbering wheels. The electromechanical actuators are preferably arranged completely within the numbering mechanisms and are mechanically autonomous. They preferably have a plurality of independent drive units for actuating a corresponding plurality of numbering wheels. A portion of the total numbering wheels may be actuated by independent drive means, and a remaining portion of the numbering wheels may be manually operable. Each drive device may have at least one electric motor, which is the assigned numbering wheel via a gear arrangement drives. The gear arrangement preferably has a first reduction factor. The electric motor may be a brushless DC motor with electronic commutation. Each electric motor may be coupled via a reduction gear with the gear assembly. Preferably, the reduction gear provides an additional reduction of the output speed of the electric motor to the gear assembly. The reduction gear may preferably be a miniature planetary gear. Alphanumeric or other symbols to be printed on the numbering wheels may be raised and reversed to allow for indirect high pressure.

The rotatable retaining element is preferably circular cylindrical. Alternatively, it may be approximately circular cylindrical, i. have an at least approximately rotationally symmetrical lateral surface, which is formed by rotation of a surface line, which is also only approximately straight. The holding element is preferably rotatable about its longitudinal axis. The rotary (longitudinal) axis of the holding element with the numbering works attached thereto is arranged in a plane parallel or approximately parallel to a line of contact of the printing material with the numbering and perpendicular or approximately perpendicular to the transport direction of the printing material in the printing press or the printing unit. The rotational speed of the holding element depends on the feed rate of the printing material relative to the printing forme device. Preferably, the linear speeds of the printing material and the peripheral speed of the printing forme device with the numbering works in a plane in which they touch the substrate during the printing process, are the same.

The at least one numbering is mounted on the rotatable support member, the attachment allows an adjustment of the position of the numbering on the support member. This adjustability is preferably realized substantially parallel to the axis of rotation of the holding element and indeed substantially perpendicular to the transport direction of the printing material. Alternatively or additionally, the adjustability can also be realized substantially parallel to the lateral surface of the retaining element and substantially parallel to the transport direction. By these possibilities of adjustability adjustment of the setting of the printing position on the substrate is realized. In yet another embodiment variant, alternatively or in addition to the above possibilities, it may also be provided that the position of the numbering mechanism on the holding element in the radial direction, that is to say in the radial direction, that is, in the radial direction. whose height above the substrate, is adjustable. Thus, further adjustments of the pressure of the identification marks can be made.

As a result of the rotation of the holding element with the numbering mechanisms attached thereto, the latter are respectively positioned over defined locations of the printing material during the rotation of the printing form device, so that the identification markings can be printed on the printing material by means of the numbering mechanisms. The number works are preferably releasably attached to the support member. For example, the number works by means of brackets, for example, each two brackets for a numbering, namely one each on two opposite sides of the numbering works, and / or be attached by means of a sliding guide on the holding element. For this purpose, for example, holding element rings can be located on the holding element, which are connected either releasably or non-detachably to the holding element, or the holding element is on the outside formed to the holding element rings are integrally formed with the holding element. The number works can preferably be releasably attached to these retaining element rings. The retaining element rings preferably comprise the retaining element on a path running perpendicular to the axis of rotation. The retaining element rings have for fixing the number of works for this purpose suitable fasteners, or these fasteners are provided together on the numbering works or on both components. For example, projections for attaching (resilient) clamps, sliding guides (for example, dovetail guides) or the like may be provided on the holding element rings, for example.

In order to solve in particular the problem that the deviation of the actual position of a print field for a print object from its desired position on the substrate on which an identification mark is to be printed depends on where the respective print field is on a printing material sheet or a substrate web is, is provided in a preferred embodiment of the present invention, that the position of each numbering is independent of the positions of other numbering works on the holding element adjustable. As stated above, the distortion of the printing material by the printing process in the printing press on the leading edge of the printing material is stronger than at the trailing edge. In addition, of course, there is also a difference between running in edge regions of gradient paths to a central gradient path (where at most a negligible deviation of the actual position adjusts to the desired position). Therefore, the requirements for a position adjustment for the different numbering works on the holding element are different.

In a simplified embodiment of the present invention, however, are all Number works, which are arranged in the same plane perpendicular to the holding element axis only jointly adjustable. For example, all the number of works that are attached to a retaining element ring, be jointly adjustable. For this purpose, the holding element ring can be adjustable relative to the holding element, ie the holding element ring is displaceable on the holding element in the axial direction, and / or the holding element ring can be rotated relative to the holding element.

In a further preferred development of the present invention, the at least one numbering unit can be adjusted by means of one actuator each. For example, the actuator may be an electromechanical actuator, preferably a servo motor, namely a position-controlled servo drive, which is formed by a servomotor with a servo drive. The servo motor may be any motor, such as a DC motor, asynchronous motor or synchronous motor. The actuator can by means of a transmission, preferably a reduction gear, act on the numbering, so that it is movable for position adjustment along an adjustment parallel or perpendicular to the axis of rotation or in the circumferential direction of the support member. For this purpose, the actuator and possibly a transmission can be arranged within the holding element, if this has an interior for receiving the actuator and the transmission.

In a further preferred embodiment of the present invention, at least one sensor is provided with which the respective deviation of the actual positions of the identification marks from their desired positions can be determined.

For this purpose, the at least one sensor can be arranged at a location in the transport direction behind the printing unit in the vicinity of the movement path of the printing material so that it preferably detects the position of printed objects, for example banknote printing objects, and the identification marks contained therein without contact, for example by means of optical, magnetic , electromagnetic or other detection methodology, so that from the actual position of the print fields for the print objects and / or the marker fields for the identification marks on the substrate can be determined, calculated, for example.

The at least one sensor can either output the deviation of the actual from the desired position in the form of an electrical signal or, for example, allow an operator to visually control the positioning. For example, if the sensor is a camera, an operator can recognize, based on the visualized positions of the currently printed identification marks, whether they have been printed within the predetermined marker fields or already partially outside these fields, and if so, whether the markers are already on the edge of the boxes, but still in it. This would allow the operator to manually adjust the position of any or all of the numbering works. The operator could in this case actuate the actuators by applying control pulses to them. For this purpose, the operator can be in a control room and adjust the actuators centrally from there. Therefore, the press does not need to be opened for the adjustment process.

As a sensor, camera systems can be used, which can also be used to read, capture and control the printed serial numbers.

• (c1) Übermitteln des elektrischen Signals an den mindestens einen Aktor, der eine Position des mindestens einen Nummernwerkes auf dem rotierbaren Halteelement der Druckformvorrichtung in geeigneter Weise verstellt.

In a further preferred development of the present invention, the at least one actuator can be actuated by an electrical signal (actuating pulse) generated by the at least one sensor (inline feedback). From the electrical signal of the sensor, the actual position of the printed identification mark is first determined in each case and from this the deviation from its nominal position is calculated. This deviation results in an actuating pulse which is delivered to the actuator so that it adjusts (adjusts) the position of the associated numbering machine. Thus, the position of the at least one identification mark in method step (b) is preferably determined by means of the at least one sensor, and then the deviation of the determined position from the desired position is calculated and output in the form of an electrical signal. The sensor can output the electrical signal representing the deviation of the determined position from the desired position, wherein the method between method step (c) and method step (d) comprises the following further method step:

• (C1) transmitting the electrical signal to the at least one actuator, which adjusts a position of the at least one numbering works on the rotatable support member of the printing form device in a suitable manner.

Consequently, the control pulse can be generated either manually or as a result of regulation. Manual control requires an operator to monitor the deviation of the actual position of the identification mark from the target position. A control comprising a timing chain from the sensor via a control member to the actuator, allows automatic adjustment of the actuator.

The sensor can also be formed in this case, for example by a camera. By means of a suitable image processing The print objects and the exact positions of the identification marks or the marking fields for these markings within the printed objects can then be detected from the data determined with the camera. From these data, in turn, the actual positions of the last printed identification marks can be calculated and from these the deviations of the actual positions to the desired positions can be calculated. The deviations determined are forwarded as actuating pulses to the actuators, so that they precisely position the corresponding numbering units in a suitable manner on the holding element. Similarly, sensors based on other physical principles than the optical detection of the printed objects can also be used.

The adjustment of the positions of the numbering works can either be carried out constantly already at a deviation from an ideal position of an identification mark or only when an identification mark is no longer within the marker field or just threatens to leave this example, the next printing. In the former case, the positions of the numbering works are constantly determined between two successive printing operations, if an adjustment by a detected deviation is required. In the latter case, an adjustment takes place only when the mark at the last print made is no longer completely within the marking field or is already at the edge. For example, a smaller tolerance field can also be defined within the marking field in which the marking should always be located, wherein the actuator is then addressed for adjustment when the marking leaves this tolerance field.

In a further preferred embodiment of the present invention, the printing material is preferably formed by a printed sheet. Identification markings in marking fields can be generated on the printing substrate by means of the printing form device, the marking fields being arranged in printing fields which are arranged in a matrix having n rows and m columns. The rows are transverse to a transport direction of the printing substrate, and the columns are parallel to the transport direction. On the rotatable holding element, corresponding to the n x m pressure fields, each a numbering arranged, where n and m are integers greater than zero. These number works form segments of the printing form device.

If, for example, 40 banknotes are to be produced from a printing material sheet by printing 40 banknote prints on the back side of the printing material sheet and correspondingly corresponding prints on the reverse side, namely, for example, five banknote prints each in eight consecutive rows in the transport direction, n = 8, m = 5 result in a total of 40 identification marks (serial numbers) on the substrate sheet. If two identification marks are to be printed in each print field, a total of 80 identification marks must be printed on the printing material sheet. These can of course be produced with a single printing form device in a single printing unit, which has all, namely 80, number works. Preferably, however, first identification marks are first printed in a first printing process with a first printing unit in first marking fields and then second identification marks in a second printing operation with a second printing unit in second marking fields. The same applies in the case of even more Identifkationsmarkierungen in each pressure field. Preferably, in the above example, 40 numbering units are mounted on each of the two holding members. Preferably, however, all 80 identification marks are printed in one print run. This is preferred if the identification marks are on the same side of the banknote as in the case of the Euro 1 series or the Euro 2 series, for example.

If the subsequently separated value or security documents, for example banknotes, are to be collated into bundles with consecutive identification marking values in ascending or descending order, the identification marks on the printing material sheet are to be affixed in such a way that corresponding collation in the specified manner is possible without problems. In the above example, for example, the printing objects (banknote prints) of the first row on the printing sheet are to be provided with successive identification marks, likewise the printing objects in the subsequent rows, wherein the marking values of the identification marks of a last printing object in a row and a first printing object in the following Succession of series. If, as in the above example, a plurality of identification marks are to be applied in the area of a printed object, these are identical.

To produce these identification marks, the numbering units are to be mounted and controlled on the holding element in such a way that they can imprint the identification marks on the printed objects on the printing sheet as explained. The number works are located on the rotatable support member, for example, in a relative arrangement to each other, which corresponds to that of the print objects on the printing material, ie when unrolling the printing form device on the substrate results in the relative arrangement of the markers in the matrix-arranged pressure fields. Optionally, a plurality of numbering units are arranged in a predetermined spatial arrangement arranged to each other in order to attach a plurality of (identical) markings in the region of a printing object (printing field). At the number works, in the case of a matrix arrangement, successive marking values are set in the rows, the marking value of number works of a last matrix element of a row increasing by one unit to the marking value of number works of the first matrix element of the subsequent row. After all identification marks of a printing material sheet have been printed, the marking values of all the numbering works are set to new values, the now lowest value being one unit higher than the highest marking value of the previously printed printing material sheet. The other number sets are set as explained above.

In the above-described embodiment of the present invention, the positions of either all the numbering works can be independently adjustable. Or only the positions of some numbering works are adjustable while the positions of others are not adjustable. For example, the positions of number works located in a central transport area on the holding element can be fixed (not adjustable), while the positions of number works located in the edge area can be adjusted. Accordingly, it can be provided that, although the positions of all numbering works adjustable, some number works are not equipped with appropriate actuators, so that they can be fine tuned only manually. In this embodiment, the fact is taken into account that it is to be expected that deviations of the determined positions from the desired positions are significant only in the edge region of the printing material, while the deviations in the middle region are relatively small.

In a further preferred development of the present invention, the printing forme device can be used for use in a printing unit for direct high pressure. In this case, the printing unit in addition to at least one provided with the numbering printing block cylinder (printing forme device) each have a counter-pressure roller and at least one inking unit, wherein the printing unit is adapted to the originating from the at least one inking ink on the at least one printing forme device and there on the substrate passes. Alternatively, the indirect high pressure can be used (Letterset). In this case, the printing unit in addition to at least one provided with the numbering printing block cylinder (printing forme device) each have an inking unit that supplies color to the numbering works, also a blanket cylinder (transfer roller) to which the number works transferred the color and from the color on the substrate is transferred, and a pressure cylinder (counter-pressure roller) on. If you want to print with a single color, it is sufficient that only one inking unit and a printing forme cylinder are provided. For multi-color printing, multiple inking units and printing forme devices must be provided according to the number of colors.

In a further preferred embodiment of the invention, the printing object can be designed such that the marking fields are surrounded by a material which is imperceptible in the visible spectral range but detectable in another spectral range, for example in the IR or UV range, so that the position of a easily visible in the marking field printed identification mark, without the material surrounding the marking field and thus indicating is visually perceptible. In this case, the actual position of the identification mark is easily detected by the contrast of the identification mark, which can be detected in the corresponding spectral range, with respect to the material surrounding the marking field. The material may be in a surface area immediately adjacent to the marker field. It can be incorporated into the substrate or applied to this, for example, printed on his.

In the following description of the figures, the same reference numerals designate the same elements and / or elements having the same function.

In the 1 shown back side 102 a banknote 100 (Value document) is in the usual way by a print of a printed image (print object) 101 on a substrate 105 , here a cotton paper, made. This banknote 100 points to their unique identification on the back shown 102 an identification mark 200 in the form of a serial number of alphanumeric characters, with the serial number 200 is formed of two leading letters and ten digits. The serial number 200 is in full length in a first marker field 310 in the upper right corner of the banknote 100 printed. In addition, there is a fragment 200 ' the serial number 200 , which is made up of their last six digits, in a second check box 320 approximately in the middle in the lower half of the banknote 100 ,

Such banknotes 100 will initially be in multiple use 500 , for example, in a 5 × 8 matrix, made by a 720 mm × 650 mm sheet 500 with eight rows 520 each of five pressure fields / banknotes benefit 510.xx (in five columns 530 ) is formed ( 2 ). The printed pictures 101 ( 1 ) are in the appropriate pressure fields 510.xx printed. For example, 8,500 signatures are produced 500 per hour at a linear speed of 1.5 to 3 m / s. In each of the print fields 510.xx are the two check boxes 310 . 320 for the marks 200 . 200 ' , which are only hinted at here. The tolerance for the positioning of the markings 200 . 200 ' on the individual banknotes 100 is for example 1.2 mm.

Because the printsheet 500 be mechanically stressed by the preceding imprints, the sheet material is rolled out. This results in a trapezoidal shape, with the longer base side of the trapezoid the leading edge 501 . 501 ' (in the transport direction T in the printing machine) forms ( 4 ; Delay shown relative to the transport path TB). By that the number works 800 the printing form device 700 ( 8th ) at predetermined positions on the signature 500 . 500 ' the marks 200 . 200 ' attach, it can easily happen that the markings 200 . 200 ' not in the checkboxes 310 . 320 but partly outside of these fields 310 . 320 to be printed ( 3 ).

The printing method used for the number printing is the letter set printing method, which is an indirect high-pressure method. Alternatively, a direct printing method can be used. A printing device suitable for the letter set printing method 600 is schematic in 5 shown: The sheet 500 . 500 ' is coming from above between a pressure cylinder (counter pressure roller) 610 and a blanket cylinder 620 passed through, wherein the counter-pressure roller 610 the printed sheet 500 . 500 ' to the blanket cylinder 620 presses. An inking unit 630 supplies via intermediate transfer rollers 640 Color to the printing plate cylinder 700 (Compressor device), the number works 800 wearing. The sublime areas 811 the marking elements 810 ( 6 . 7 . 9 ) are then wetted with the paint and then press this on the blanket cylinder 620 , which decreases the printed image by color splitting. From the blanket cylinder 620 the print image is then printed on the sheet 500 . 500 ' transfer.

The printing plate cylinder 700 has the number works 800 on. Such number works 800 are known. A typical numbering 800 is in DE 20 2007 019 477 U1 described. An isometric view of such a numbering 800 is in 6 shown. This numbering 800 has several adjoining dials 815 with raised areas 811 with alphanumeric symbols on the front sides. The number plates 815 are rotatable on one axis 820 stored. The disks 815 are each from a motor with gear reduction 830 driven, so the position of each disc 815 can be adjusted individually.

The printing plate cylinder 700 is in the present case with 40 numbering works 800 equipped in an arrangement on a roller 710 sitting, the matrix-shaped arrangement of banknotes 100 on the sheet 500 corresponds, in eight rows of five numbered works 800 ( 7 . 8th ). The number works 800 form segments of the shell of the plate cylinder, but these segments do not necessarily cover the entire jacket, but only the angular range in the circumferential direction, the extent of all rows 520 of pressure fields 510.xx on the substrate 105 corresponds to 7 ). The Representations in 7 . 8th do not show that between each piece of numbers 800 Minimum distances are located, which ensure that the positions of the numbering works 800 independently of each other parallel to the lateral surface 711 the roller 710 can be adjusted. The number plates 815 the numbering works 800 stand above the periphery of the roll.

For fixing the numbering works 800 are on the roller 710 with a diameter of for example 140 mm five seat rings (holding element rings) 720 attached (not shown). The outer diameter of the seat rings 720 is for example 220 mm. These seat rings 720 embrace the roller 710 and assign for each numbering 800 They carry a recess 721 as a sliding guide in the form of a dovetail guide parallel to the surface line of the roller 710 on ( 9 ). The number works 800 even this is with a complementary dovetail 840 equipped in the dovetail guide 721 is held. This is the number works 800 on the roller 710 along the generatrices, ie in the axial direction, adjustable. The adjustment can be made by means of an actuator 850 , For example, a servomotor, be made, which is below the respective numbering 800 within the roller and receives an actuating pulse from the outside. The actor 850 acts through a through a slot in the seat ring 720 engaging driver tongue 860 of the numbering 800 , The number works 800 having printing forme cylinder 700 has a diameter of, for example, 370 mm.

For consecutive printing on a substrate 105 , For example, of matrix-shaped pressure fields 510.xx having printed sheets 500 , the number works become 800 of the plate cylinder 700 For example, initially set such that they are set to successive marking values, so for example YA123456770, YA123456771, YA123456772, ... and that of a first series of the number works 800 Starting, the marks in the banknote printing fields 510.11 . 510.12 . 510.13 at the leading edge 501 of the print sheet 500 print, and within the rows from left to right to the last row, so that the print fields 510.81 . 510.82 . 510.83 . 510.84 . 510.85 the last row 520 of the print sheet 500 the marking values ..., YA123456808, YA123456809, YA123456810 are obtained ( 2 ).

After the first sheet 500 provided with the marking values, this happens a camera (sensor) 900 that the printed sheet 500 reproduced and the data obtained to an image processing unit 910 forwards ( 4 ), where the actual positions of the printed marks 200 . 200 ' be recorded. If any of the marks 200 . 200 ' not completely within the designated marking fields 310 . 320 are arranged or are already approaching an edge of the fields, are electrical control pulses 920 to the actors 850 the numbering works 800 the printing form device 700 passed the location of the corresponding pressure fields 510.xx on the sheet 500 correspond. This will change the positions of these numbering works 800 adjusted. This position adjustment is made before the next (second) press sheet 500 ' with the marks 200 . 200 ' is provided.

Further, the marking values of the numbering works become 800 before printing the next (second) spread 500 ' switched so that they now start with the next not yet printed marking value, thus according to the above example starting with YA123456811, YA123456812, YA123456813, ... and ending with ..., YA123456848, YA123456849, YA123456850. By the position adjustment of the number works 800 become these marks 200 . 200 ' exactly in the designated marking fields 310 . 320 printed so that the required tolerances are met.

In an alternative variant, the numbering at 40 uses per sheet can be done as follows: On a first sheet, the print fields become 510.xx printed with the sequence YA000000001, YA000000101, ... to YA000003801, YA000003901. On a subsequent second arc are the pressure fields 510.xx accordingly printed with an ending digit, 2 '. Accordingly, the following sheets are printed. The hundredth sheet is printed with YA000000100, YA000000200, ... to YA000003900, YA000004000. bow 101 begins with the numbering YA000004001. The following marks are numbered YA000004101, ... to YA000007801, YA000007901. bow 200 receives the numbering YA000004100, YA000004200, ... to YA000007900, YA000008000.
