The invention has for its object to provide a method for reprinting at least one individualized printed copy, whereby by the application of an individualized printed copy, the coding for an optical

Detection device is hidden, can be determined and reprinted.

The object is achieved by the features of claim 1.

The advantages that can be achieved with the invention are, in particular, that one of a set of printed copies belonging to a specific print job taken or lost individualized printed copy is specifically and independently reprinted, ie missing in the amount of a particular print job printed copy is first identified and then reprinted to complete this amount. In addition, the proposed method has the advantage that by the application of an individualized printed copy whose coding on a hidden for a detection device side, z. B. is attached to an inside of this individualized printed copy having printed product, can be determined and reprinted.

An embodiment of the invention is illustrated in the drawing and will be described in more detail below. The drawing shows a schematic diagram by way of example and simplifies a device for carrying out the method according to the invention.

Print jobs increasingly include the feature that at least a portion of the printed copies belonging to a quantity of the respective print job are to be executed individually. An individualization of at least one printed copy from this set of printed copies takes place z. B. in that the individualized copy to be individualized by the pressure of a coding. The coding consists z. B. from an impression in a given target area in or on a

Printed image of the relevant printed copy, wherein the printed image on a substrate in a z. B. rectangular field or printing frame is formed, this field or this printing frame dimensions on the order of z. B. a DIN A5 page or larger. The target area is also z. B. formed as a rectangular field and has dimensions of the order of z. B. 100 mm by 75 mm. The coding has z. As an address and / or numbering. With a printed address, the printed copy in question is personalized and can z. B. be delivered personally. The coding takes place z. B. systematically by z. B. a stored in a memory address list is processed to print by the printing of the various addresses copies for. B. certain recipients to assign, or stochastically, if at random. B. Lot numbers of a game of chance will be awarded. The coding is thus one in the relevant one

Print job variable information, which during a printing process a

Printed copy with otherwise consistent information is added to the copy in question from the other copies of that concerned

Make a print job distinguishable. This variable information is z. B. from a cooperating with a control unit database, in particular the control unit and database of a production planning system, provided on a customizing print engine of a printing press. At a the

individualized printed copy containing multi-page printed product is the coding of the relevant printed copy z. B. on an inside of this

Printed product arranged so that this coding mounted on the finished printed product hidden and thus not externally noticeable, especially not automated by an optical, preferably camera-based inspection system.

Apart from the coding consists of the amount of belonging to a particular print job, in connection with the customization exporting printing printed copies z. B. from otherwise identical printed copies. The

Print images belonging to the print job in question printed copies are in particular multicolored z. B. in an offset printing process or in a

Gravure printing printed, wherein for the individualization of the at least one printed copy a digital printing process exporting printing unit is used. However, it can also be provided that the print copies of the relevant print job are printed exclusively in a digital printing process, d. H. the coding and the remaining print image or the remaining print images of the respective printed copy are each printed in a digital printing process.

Digital printing processes are z. B. executed by at least one inkjet head having printing unit. The amount of printed copies belonging to a particular print job is also referred to as its run. It can be provided that in the relevant edition, ie in the amount of printed copies belonging to a particular print job, several or all print copies are individualized.

The printed copies belonging to the quantity of a specific print job are printed on a web-shaped printing material or on a sheet

printed substrate printed. The substrate can be made of paper, plastic, metal or a multi-component material, eg. B. from a coated

Support material or of a material having a multilayer structure, be formed. Depending on the selected substrate in a web press or in a

Sheet-fed printing machine printed, with the press in question

Transport direction of the substrate in succession comprises a plurality of printing units, of which at least one printing unit performs a digital printing process for the individualization of at least one printed copy in the relevant print job. For the production of an individualized printed copy it is irrelevant, if at the

Processing of the relevant print job initially a z. In one

Offset printing process or printed in a gravure printing process printed on the substrate in question and then the coding in the specified

Target surface of the relevant printed copy is introduced or whether these two manufacturing steps are performed in reverse order.

To produce a salable i. d. R. multi-sided printed on both sides printed product such. As a newspaper, a magazine, a leaflet or a book of z. B. web-shaped substrate, the to the relevant

Print job belonging to printed copies, with other printed copies, z. B. merged with other printing material. A web-shaped substrate is z. B. cut in a belonging to the printing press folder in individual signatures and / or folded. In addition, for the production of the

salable print product further manufacturing steps may be provided such. B. a Collecting and summarizing a plurality of signatures or other product parts belonging to the respective printed product and / or gluing and / or stapling respectively individual and / or collected signatures or product parts. Further production steps can take place outside of the printing press in a further processing subsequent to the printing press. In this respect, the term "print copy" on a single sheet, on a single signature, on one already eg in a

Faltapparat machined product part or even on the preferably salable printed product as a whole refer. The prints produced by the printing press are z. B. by means of a preferably continuous conveyor system z. B. lying in a shingled stream on a belt conveyor or successively transported in a row on a suspended conveyor hanging to their respective processing or to their respective leaving the printing shipping point. At a pressure point of the printing unit, which is the at least one printed copy

individualized, thus begins a route that from these printed copies to

Completion of salable print products. According to one aspect of the invention, the amount of printed copies printed in the given print job for the production of the intended print run by means of a z. B. formed as an optical system control device

Completeness of the printed copies belonging to this quantity. This route extends z. For example, up to the shipping point at which to the amount of printed matter belonging to the specific printed copies are shipped leaving the printing.

The automatically performed by means of the control check for completeness of belonging to the edition concerned printed copies is advantageous because it has been shown that in practice during an ongoing production along the traversed by the print copies track again and again a subset of the specific Print copies for different reasons, from the set of print copies belonging to this print job is removed. One reason is z. B. in that the introduced into the specified target area of the relevant copy to be individualized copy and / or the rest of the printed image of the relevant copy to be individualized is executed or are and therefore the faulty printed copy or the faulty printed copies z. B. at the behest of the operator of

Printing machine or due to a control command of a print quality monitoring device, in particular one preferably with at least one camera

equipped inspection system, eg. B. is discharged by an operation of a Makulaturweiche from the amount of belonging to this print job copies or will be. The removal of at least one nachzudruckenden

Printed copies can thus be made on the basis of a detected fault in the at least one printed copy individualizing printing unit. Another reason may be that z. B. from the operator of the printing press a single individualized printed copy or several such printed copies z. B. are taken for a random visual inspection from the amount of printed copies belonging to this print job. However, whenever at least one individualized printed copy is taken from the quantity of printed copies belonging to the particular print job, a gap arises in the quantity of printed copies belonging to this print job, whereby the execution of the print job becomes incomplete. In order to carry out the print job in full, in particular the at least one extracted individualized print copy must be reprinted, i. H. reprint. In order to be able to reprint the at least one individualized print copy that has been taken, the respective printed copy taken, which differs on account of its individualization from the other print copies of the current print job, is preferably automated by means of a print job

Identification device to identify. The identification of the relevant

taken individualized printed copy is just then not trivial if the individual copy of the copy in question concealed, especially on a hidden for a detection device side, z. B. on an inside of the Printed product is attached, because then this coding with a print quality monitoring system, eg. With one as an optical inspection system

trained detection device is not detectable.

The at least one individualized printed copy to be reprinted is taken at one location from the set of printed copies printed in the particular print job along the route between the printing unit of the printing unit that has this at least one printed copy individualized, and one end of this section lies. The removal takes place z. B. by means of a arranged in this route, in particular controllable by a control unit

Makulaturweiche, this control unit z. B. is connected to another control unit controlling the printing machine or integrated in the machine control. A length of the path in question starting from the pressure point of the printing unit, this at least one of the amount of in the particular

Print job printed copies has individualized printed copy, up to the place of removal of this at least one printed copy of the amount of copies printed in the specific print copies is from a z. B. in a control station of the printing press arranged control unit, in particular the machine control determined. Likewise, alternatively or in addition to the length of the path concerned z. A copy of the printed matter printed in the particular print job up to the place of removal of the relevant one

individualized printed copy of the amount of copies printed in this particular print job time determined by the relevant control unit. Thereafter, based on the determined to the place of removal of the relevant printed copy length of the path and / or on the basis of the determined time the respective extracted individualized printed copy is identified by this control unit, wherein the control unit is part of the identification device. On the basis of this identification, the at least one identified is identified

Printed copy supplementing the amount printed in the particular print job Printed copies reprinted from the at least one printed copy individualizing printing unit of the printing press on the basis of one of the aforementioned identification device or its control unit to this printer output signal. The at least one printed copy to be reprinted in addition to the amount of printed in the particular print job printed copies of the at least one print copy individualizing printing is then reprinted during the execution of the specific job or following this print job. The control unit used to identify the respective individualized printed copy taken may in conjunction with the machine control of the printing press or at least one with the

Machine control of the printing machine cooperating control unit may be formed.

In an advantageous development, the length of the path, starting from the printing point of the printing unit, which has this at least one of the set of printed in the particular print job printed copies of printed copies individualized to the place of removal of the relevant printed copy from the amount of in the determined print job printed copies based on at least one of the control unit provided signal of a virtual master axis, wherein the virtual master axis is used at least for a control of the at least one printed copy individualizing printing unit. The determination of the location at which the relevant printed copy is taken from the amount of printed copies printed in the particular print job, and / or the identification of the individualized printed copy taken z. B. using a valid for the transport of printed copies speed signal and a time signal, which required for the determination of the sampling location and / or for the identification of the extracted individualized printed copy

Speed signal and time signal of the determining control unit z. B. be provided by the virtual master axis. Fig. 1 illustrates again the facts described above. A substrate 01, z. As a material web of paper, plastic or metal, in particular aluminum, is transported in a continuous printing process in a transport direction T and thereby in a printing machine with at least one in an offset printing process or a gravure printing printing unit 02 and at least one printing in a digital printing process printing unit 03 printed, wherein at least one of the printed on the substrate 01 with the at least one in the offset printing process or the gravure printing printing unit 02 printed copies by the at least one printing in the digital printing process printing unit 03 is individualized by the impression of coding. At a printing point of the at least one printed copy individualizing printing unit 03 starts a distance s, which is to be traversed by the amount of belonging to a particular print job copies. This route s ends z. B. at a shipping point 04, leave the printed copies of the printing. Within this distance s, the quantity of printed copies printed in the particular print job is determined by means of a

Control device, z. B. a preferably optical inspection system 1 1 checks for completeness of belonging to this set printed copies out. Within this route s is also z. B. a Makulaturweiche 06 arranged, these

Makulaturweiche 06 is arranged in particular in the transport direction T of the printed copies in a range of distance s after a folder 09. The transport to the amount of printed matter belonging to a specific printed copies takes place in particular between the folder 09 and the shipping point 04 by means of one of these printed copies z. B. in a scale flow continuously conveying conveyor. The printing units 02; 03, the folder 09 and the Makulaturweiche 06 and trained as an inspection system 1 1 control device are connected to a control unit 07, z. B. connected to the machine control for the printing press. In the preferred embodiment, this control unit 07 also receives further signals, in particular from a virtual master axis 08 controlling the printing machine virtual master axis 08 signals provided to the identification device includes at least one speed signal v, which indicates the speed with which the printed copies are transported along the route s, in particular with which speed the extracted individualized printed copy has been transported along the route s. The speed of the copies is z. B. up to 15 m / s. If the location at which at least one individualized printed copy is taken from the quantity of printed copies belonging to a particular print job, and thus the length I of the path from the individualizing printing unit 03 to the picking location, the control unit 07 identifies the relevant at least one printed copy taken based on the time t, which elapsed from the individualization of this printed copy by means of the individualizing printing unit 03 until its removal from the quantity of printed copies belonging to a specific print job. If the location at which at least one individualized print copy is taken from the quantity of printed copies belonging to a particular print job is not known, because e.g. B. operator of the printing press at least one individualized printed copy at any location along the route s from the amount of belonging to a particular print job

Prints out copies, then determines the control unit 07 preferably first the length I of the path from the individualizing printing unit 03 to the sampling and then identifies as before the relevant at least one printed copy on the basis of the time t, the individualization of this printed copy by means of the individualizing printing 03 to to extract it from the quantity of printed copies belonging to a particular print job has elapsed. Because of the time t, the individualization of this printed copy by means of the

individualizing printing unit 03 has elapsed until its removal from the amount of belonging to a particular print job copies, the relevant extracted individualized printed copy can be determined uniquely, since the date on which the copy in question was individualized in it individualizing printing unit 03, known and z , B. has been stored in the control unit 07. The identification of the respective individualized printed copy taken from the quantity of printed copies belonging to a particular print job takes place in both of the aforementioned variants (picking location known or not known)

preferably using the control unit 07 supplied
