Abstract

A printing machine (1) with at least one printing unit (4-7) is proposed in which there are a multiplicity of sensors for monitoring the printing operation and a multiplicity of actuators for the adjustment of, for example, the ink profile, the moisture profile, the paper guidance and the like. The complete processing of the sensor signals, their integration and the output of adjustment signals as well as of display signals takes place in a comprehensive electronic control unit (11), which is connected by data leads (21, 22) with the printing machine or with the sensors and the actuators in the printing machine (1). The comprehensive electronic control unit (11) is, furthermore, connected to measuring instruments, for example a printing plate reader (12) or a quality inspection facility (13), and the measurement signals for adjustment of the printing machine are correspondingly processed. The monitoring of the printing operation and, possibly, necessary interventions in the control of the printing machine take place via a control panel (15), which is connected to the comprehensive electronic control unit (11) by means of a data lead (26). The printing machine itself does not include any additional electronic or electrical control devices apart from the sensors and actuators other than the display indicators necessary for the monitoring of the printing operation on the machine, or operating facilities. <IMAGE>

Description

i DK 167481 B1in DK 167481 B1

Opfindelsen vedrører en trykmaskine med mindst ét trykværk, indeholdende et antal måleindretninger, sensorer der frembringer elektroniske signaler, elektronisk styrbare indstillingsorganer, aggregater og 5 mindst én styre- og overvågningspult til overvågning, styring og regulering af hele trykforløbet.The invention relates to a printing machine having at least one printing plant, comprising a number of measuring devices, sensors which produce electronic signals, electronically controllable setting means, aggregates and at least one control and monitoring desk for monitoring, control and regulation of the entire printing process.

I EP offentliggørelsesskrift nr. 0 160 167 beskrives en fremgangsmåde og en indretning til elektronisk styring af en trykmaskine. I denne er separate pro-10 cessorer anbragt direkte på trykmaskinens aggregater eller i trykmaskinen. Data fra disse separate processorer ledes til en central kontrolenhed gennem lange dataledninger. Dette resulterer i såvel uheldige forstyrrelser som en langsom dataudveksling.EP Publication No. 0 160 167 discloses a method and apparatus for electronically controlling a printing machine. In this, separate processors are placed directly on the aggregates of the printing machine or in the printing machine. Data from these separate processors is routed to a central control unit through long data lines. This results in both unfortunate interruptions and slow data exchange.

15 Fra DE patentansøgning nr. 27 28 738 kendes en trykmaskine, der har flere som indstillingsorganer over trykbredden anbragte farvedoseringselementer, der kan indstilles via en indstillingsindretning. Den på trykarket frembragte farvetæthed aftastes via egnede sensorer, 20 og efter en sammenligning mellem bør-værdierne og er-værdierne korrigeres farvedoseringselementernes indstilling.15 from DE patent application no. 27 28 738 is known a printing machine having several color dosing elements arranged as adjusting means over the width of the pressure which can be adjusted via a setting device. The color density produced on the print sheet is sensed by suitable sensors, and after a comparison between the set values and the values, the setting of the color dosing elements is corrected.

Yderligere kendes fra DE offentliggørelsesskrift nr. 28 30 085 en fremgangsmåde til visning af en trykma-25 skines indstillingsparametre, ved hvilken fremgangsmåde trykmaskinen zonevis har indstillingsorganer til dosering af farve- og/eller fugtighedsstyringen, og hvor indstillingsparametrene via sensororganer omformes til signaler, således at den indstillede farveprofil kan 30 vises.Further, from DE Publication No. 28 30 085 there is disclosed a method for displaying the setting parameters of a printing machine, in which method the printing machine has zone setting means for dosing the color and / or humidity control, and wherein the setting parameters are converted via signals to signals. the set color profile can be displayed 30.

Som bekendt har trykmaskiner, f.eks. offset-ark-trykkemaskiner, et yderligere antal sensorer, f.eks. til overvågning af papirløbet eller papirpålægget og -udlægget eller af påføringen af fugtmiddel, og der er ligele-35 des et yderligere antal indstillingsorganer, f.eks. til indstilling af registeret. Desuden er det nødvendigt at 2 DK 167481 B1 have styreindretninger til hoveddrevet og til hjælpedrev. Ved de kendte trykmaskiner er den decentrale, dvs. den over hele maskinen fordelte placering af forskellige elektroniske regulerings- eller styreindretninger en 5 ulempe. Hver af disse indretninger kræver i det mindste sin egen energiforsyning og omfatter en selvstændig signalbehandling (intelligens) med begrænset behandlingsmulighed .As is well known, printing machines, e.g. offset sheet printing machines, a further number of sensors, e.g. for monitoring the paper flow or the paper coating and deposition or the application of wetting agent, and there are also a further number of adjusting means, e.g. for setting the register. In addition, it is necessary that 2 DK 167481 B1 have control devices for the main drive and for auxiliary drives. In the known printing machines it is decentralized, ie. the disadvantage of the placement of various electronic control or control devices throughout the machine is a disadvantage. Each of these devices requires at least its own power supply and includes a self-contained signal processing (intelligence) with limited processing capability.

Det er yderligere en ulempe, at de i de enkelte 10 elektroniske enheder behandlede data ikke umiddelbart står til rådighed eller f.eks. kun kan udveksles indbyrdes eller samlet ved forøgede udgifter til dataledninger. Desuden reduceres dataudvekslingshastigheden som følge af de længere dataledninger og støj indflydelsen 15 forøges. Desuden kræves der mere tid til afprøvning af disse elektronikenheder.A further disadvantage is that the data processed in each of the 10 electronic devices is not immediately available or e.g. can only be exchanged with one another or together at increased data line costs. In addition, due to the longer data lines, the data exchange rate is reduced and the noise influence 15 is increased. Furthermore, more time is required for testing these electronic devices.

Hensigten med opfindelsen er således at forenkle styringen og reguleringen af en trykmaskine under samtidig besparelser på indretninger til energiforsyning og 20 til databehandling. Yderligere er det hensigten at dataudvekslingshastigheden skal forhøjes og støj indflydelsen skal reduceres som følge af de kortere dataledninger.The object of the invention is thus to simplify the control and regulation of a printing machine while at the same time saving on devices for energy supply and for data processing. Further, the data exchange rate is intended to be increased and the noise influence reduced as a result of the shorter data lines.

Denne hensigt nås ifølge opfindelsen med en tryk-25 maskine af den indledningsvis angivne art, der er ejendommelig ved, at fra de på trykmaskinen anbragte måleindretninger, sensorer, indstillingsorganer, aggregater og styre- og overvågningspulten er signal- og forsyningsledningerne for de af sensorerne, indstillingsorga-30 nerne og aggregaterne leverede signaler umiddelbart udformet til en uden for trykmaskinen anbragt dataforarbejdnings- og styreindretning, som en fælles, af elektronik til signalbehandlingen og energistyringen bestående totalelektronik, der også leverer driftsenergien 35 til hoved- og hjælpedrev på trykmaskinen, og med hvilken styringen, reguleringen og signalind- og udgangen gen- 3 DK 167481 B1 nemføres ved hjælp af de fra databehandlings- og styreindretningen bearbejdede styresignaler fra de til trykmaskinen tilordnede måleindretninger, sensorer, indstillingsorganer, aggregater og styre- og overvågningspul-5 ten.This object is achieved according to the invention with a printing machine of the kind mentioned initially, characterized in that from the measuring devices, sensors, adjusting means, assemblies and the control and monitoring desk, the signal and supply lines for the sensors are arranged on the printing machine. the tuning means and assemblies provided signals immediately formed into a data processing and control device, arranged as a common, electronics for the signal processing and energy control, comprising total electronics, which also supply the operating energy 35 to the main and auxiliary drives of the printing machine, and with which the control, regulation and signal input and output are transmitted by the control signals processed from the data processing and control device from the measuring devices, sensors, adjusting means, aggregates and the control and monitoring pulse assigned to the printing machine.

En fordel ved opfindelsen er såvel den samlede behandling af samtlige sensorsignaler som den samlede koordination af indstillingssignalerne ved hjælp af databehandlings- og styreindretningen, der i det følgende 10 også kaldes totalelektronikken. P.eks. styres og vises funktioner som papirtransporten, papirpålægningen og -udlægningen, farve- og fugtmiddelpåføringen, farvetør-ringen og pudringen. Tilstanden af maskinen eller af måleindretningerne og af aggregaterne, såsom maskinhastig-15 heden, indfarvningen og indfugtningen af pladecylinderen, registerstillingen, måleudstyrets funktionsdygtighed eller de til rådighed værende mængder af hjælpestoffer og andre oplysninger kan som følge af den fælles overvågning evalueres som udtryk for et korrekt tryk-20 ningsforløb. Desuden står samtlige trykmaskinens data centralt til rådighed og er centralt tilgængelige. Yderligere kan den samlede maskinstyring, der hidtil er udført som en beskyttelsesstyring, der som bekendt kun har en lille grad integration, nu foretages af en total-25 styring, hvorved den større integration muliggør optimering af trykningsforløbet under forskellige driftsbetingelser. Databehandlingshastigheden forøges som følge af de kortere dataveje og samtidig fås en større sikkerhed mod forstyrrelser.An advantage of the invention is both the overall processing of all the sensor signals as well as the overall coordination of the tuning signals by the data processing and control device, which in the following is also called the total electronics. P.eks. functions such as the paper transport, the paper laying and laying, the coloring and wetting agents, the color drying and the powdering are controlled and displayed. The condition of the machine or of the measuring devices and of the aggregates, such as the speed of the machine, the dyeing and wetting of the plate cylinder, the register position, the operation of the measuring equipment or the available quantities of auxiliaries and other information can be evaluated as a result of the joint monitoring. printing process. In addition, all data from the printing machine are centrally available and centrally available. Furthermore, the overall machine control, hitherto performed as a protection control, which, as is well known, has only a small degree of integration, can now be carried out by a total control, whereby the greater integration enables optimization of the printing process under different operating conditions. The data processing speed is increased as a result of the shorter data paths and at the same time a greater security against interruptions is obtained.

30 Den ovenfor beskrevne samlede indretning består eksempelvis af flere enkeltregneenheder, der under overvågning af mindst én hovedregneenhed behandler de af trykmaskinen leverede data og frembringer styresignaler.The assembled device described above, for example, consists of several single calculator units which, under the supervision of at least one main calculator unit, process the data supplied by the printing machine and produce control signals.

Et sådant system kendes også under begrebet flerproces-35 sorsystem. Det er en fordel ved dette system, at der mellem de enkelte processorer kan skabes meget korte da- 4 DK 167481 B1 taveje, der garanterer en stor sikkerhed mod forstyrrelser. Hele dataudvekslingen foregår således inde i en enkelt enhed, således at unødvendigt lange dataledninger bortfalder. Kendte systemer har som regel decentrale 5 processtyresystemer, der er forbundet med hinanden via en kommunikationsenhed eller via en overordnet central regneenhed. Disse systemer har dog den mangel, at der må overvindes meget lange dataveje med de hertil hørende, kendte risici for følsomhed over for forstyrrelser. Des-10 uden må der ved anvendelse af et sådant system ved trykmaskinen regnes med yderligere forstyrrende indflydelser fra svingninger og temperaturændringer, og desuden er vedligeholdelsen af flere enkelte systemer væsentlig dyrere.Such a system is also known under the concept of multi-processor system. It is an advantage of this system that very short data paths can be created between the individual processors, which guarantee a high level of security against interference. The entire data exchange thus takes place within a single unit, so that unnecessarily long data lines are lost. Known systems usually have decentralized 5 process control systems which are connected to each other via a communication unit or via an overall central calculator. However, these systems have the disadvantage that very long data paths must be overcome with the associated known risks of sensitivity to interference. In addition, using such a system at the printing machine, additional disruptive influences from fluctuations and temperature changes must be taken into account, and the maintenance of several single systems is considerably more expensive.

15 Det er en yderligere fordel ved flerprocessorsy stemet, at ved udfald af en enkelt processor blokeres det samlede system ikke, idet denne processors funktioner overtages af de andre processorer, hvorved trykmaskinen ikke skal tages ud af drift.It is a further advantage of the multi-processor system that in the case of a single processor failure, the overall system is not blocked, since the functions of this processor are taken over by the other processors, thereby eliminating the printing machine.

20 Med denne totalelektronik er det uden videre mu ligt at inkorporere ikke blot trykmaskinens funktioner, men også de tilhørende indretningers funktioner, som f.eks. papirpålægningen og -udlægningen, tørreindretningen og lignende i processtyringen.20 With this total electronics, it is possible to incorporate not only the functions of the printing machine, but also the functions of the associated devices, such as e.g. the paper laying and laying, the drying device and the like in the process control.

25 Totalelektronikken er fortrinsvis placeret i en enkelt styrepult. Foruden at gøre det lettere at udføre service medfører denne centrale placering også den fordel, at der kun er behov for en enkelt spændingsforsyning og køleindretning. Yderligere er det ved hjælp af 30 denne indretning muligt hurtigt at vise trykkeren alle de for ham relevante data, f.eks. de til trykoptimering nødvendige data.The total electronics are preferably located in a single control desk. In addition to making servicing easier, this central location also has the advantage of requiring only a single power supply and cooling device. Further, by means of this device it is possible to quickly display the printer all the data relevant to him, e.g. the data needed for pressure optimization.

Det er en yderligere fordel ved opfindelsen, at databehandlings- og styreindretningen kan opbygges som 35 en unverisal totalelektronik, dvs. at trykmaskiner af forskellige størrelser og opbygninger kan styres. Ved 5 DK 167481 B1 placeringen af databehandlings- og styreindretningen uden for trykmaskinen undgås en tilpasning af enkeltstyringer til forskellige af maskinens komponenter, hvilket indtil nu var nødvendigt som følge af den angivne kon-5 struktive opbygning.It is a further advantage of the invention that the data processing and control device can be constructed as a unverisal total electronics, ie. that printing machines of various sizes and structures can be controlled. The location of the data processing and control device outside the printing machine avoids the adaptation of single controllers to various of the machine components, which was heretofore necessary as a result of the specified structural construction.

I en anden udførelsesform af opfindelsen er databehandlings- og styreindretningen opdelt i to enheder, hvorved den første enhed behandler alle til farvestyrin-gen nødvendige data som f.eks. farvepåføringen og regi-10 sterindstillingen, og de øvrige data behandles i den anden enhed. Dette har den fordel, at farvestyringen kan foretages der, hvor det er muligt at gennemføre en bører- sammenligning mellem trykproduktet og foreliggende kriterier, f.eks. ved hjælp af et mønsterark.In another embodiment of the invention, the data processing and control device is divided into two units, whereby the first unit processes all data needed for the color control such as e.g. the color application and the register setting, and the other data is processed in the other unit. This has the advantage that color management can be done where it is possible to perform a stock comparison between the print product and the present criteria, e.g. using a pattern sheet.

15 En tredje udførelsesform af opfindelsen er rettet mod en hensigtsmæssig opbygning af databehandlings- og styreindretningen. En hovedregneenhed er via en fælles databus forbundet med enkelte regneenheder, idet det dog er muligt også at lade flere hoved regneenheder arbejde 20 sammen i et sammenhængende system. De enkelte regneenheder har den opgave hver for sig at styre eller overvåge bestemte af trykmaskinens funktioner eller tilstande.A third embodiment of the invention is directed to an appropriate construction of the data processing and control device. A master calculator is connected to a single calculator via a common data bus, although it is also possible to have several main calculators work together in a coherent system. Each calculator has the task of individually controlling or monitoring certain functions or modes of the printing machine.

Det er ligeledes muligt under visse omstændigheder, at en regneenhed kan overtage en anden enheds opgave.It is also possible in some circumstances that a unit of account may take on another unit's assignment.

25 I en fordelagtig udførelsesform af opfindelsen er en ekstern dataledning forbundet med databehandlings- og styreindretningen, f.eks. for at foranstaltninger i forbindelse med forberedelsen af arbejdet, såsom den konstaterede profil, papirtykkelsen, styktallet og forind-30 stillingsdata for trykmaskinen, kan indgives via en ekstern inddataenhed. Desuden kan der via denne eksterne dataledning hentes data eller diagonosedata, eksempelvis gennem tilslutning af fejldiagnoseudstyr eller via telefondiagnose fra enheden, da alle data er til rådighed i 35 denne enhed.In an advantageous embodiment of the invention, an external data line is connected to the data processing and control device, e.g. so that measures related to the preparation of the work, such as the profile found, the thickness of the paper, the number of pieces and the preset data for the printing machine, can be administered via an external input device. In addition, via this external data line, data or diagonal data can be retrieved, for example, through the connection of fault diagnosis equipment or via telephone diagnosis from the device, since all data is available in this unit.

I en yderligere udførelsesform af opfindelsen frembringes indgangssignalerne eller i det mindste be- 6 DK 167481 B1 stemte indgangssignaler til den nævnte indretning via sensorer. Disse sensorer kan i en alternativ udførelsesform have efterkoblede mellemforstærkere, der hæver et svagt sensorsignal til et støj sikkert niveau.In a further embodiment of the invention, the input signals or at least intended input signals are generated to said device via sensors. These sensors may, in an alternative embodiment, have post-coupled intermediate amplifiers that raise a weak sensor signal to a noise safe level.

5 I yderligere udførelsesformer kan den direkte styring af indstillingsorganerne ske via totalelektronikken med laveffekt. Hertil kræves der ganske vist egnede, dvs. ligeledes med laveffekt omskiftbare indstillingsorganer. Dette har den fordel, at en tilpasning 10 af totalelektronikkens udgangssignaler til indstillingsorganer med høj indgangseffekt bortfalder. Desuden er det ved anvendelse af laveffekt muligt at anvende fladkabler til overføring af disse effekter, hvilke kabler har den velkendte fordel, at de kræver mindre plads og 15 er lette at håndtere.In further embodiments, the direct control of the adjusting means may be effected via the low-power total electronics. Admittedly, suitable for this, ie. likewise with low-power switchable adjusting means. This has the advantage that an adaptation 10 of the total electronics output signals to high input power setting means is eliminated. Furthermore, using low power, it is possible to use flat cables to transmit these effects, which cables have the well-known advantage that they require less space and are easy to handle.

Indretningens display- og indtastningsmuligheder eller betjeningselementer er ifølge en udførelsesform af opfindelsen samlet i en styre- og overvågningspult.According to one embodiment of the invention, the display and input options or controls of the device are assembled in a control and monitoring desk.

Denne pult kan danne en enhed med databehandlings- og 20 s tyre ind retningen, men det er også muligt at placere denne pult adskilt fra indretningen og forbinde den til indretningen med ledninger. Det er eksempelvis også muligt at tilslutte et pudringsapparat via databehandlings- og styreindretningen. Dette apparat har ganske 25 vist en intern styring, men kan også forsynes med data, henholdsvis signaler fra indretningen, eksempelvis vedrørende maskinhastigheden eller farveegenskaberne.This desk can form a unit with data processing and 20 s bullets in the direction, but it is also possible to place this desk separately from the device and connect it to the device with wires. For example, it is also possible to connect a powder apparatus via the data processing and control device. Although this apparatus has an internal control, it can also be provided with data or signals from the device, for example regarding the machine speed or the color characteristics.

Yderligere fordelagtige udførelsesformer af opfindelsen er angivet i det følgende og i underkravene.Further advantageous embodiments of the invention are set forth below and in the subclaims.

30 Opfindelsen vil nu blive forklaret ved hjælp af to udførelseseksempler og med henvisning til tegningen, på hvilken fig. 1 i diagramform viser opbygningen af en trykmaskine med en tilhørende databehandlings- og styre-35 indretning, og fig. 2 viser en variant af den i fig. 1 viste databehandlings- og styreindretning.The invention will now be explained by means of two embodiments and with reference to the drawing, in which fig. 1 is a diagram showing the structure of a printing machine with an associated data processing and control device; and FIG. 2 shows a variant of the embodiment shown in FIG. 1 and the data processing and control device.

Pig. 1 viser en offset-arktrykkemaskine 1 bestående af flere trykværker 4-7, en arkpålægger 2, en arkudlægger 3 og en drivmotor 8. Betjeningen sker via arkpålæggeren 2's betjeningspanel 9. Yderligere er 5 der på arkudlæggeren 3 et betjeningspanel 10, på hvilket f.eks. maskinens hastighed vises, og fra hvilket det er muligt at foretage indgreb i maskinstyringen.Pig. 1 shows an offset sheet printing machine 1 consisting of a plurality of printing plants 4-7, a sheet applicator 2, a sheet dispenser 3 and a drive motor 8. The operation is carried out via the sheet panel 2's control panel 9. Further, 5 on the sheet drawer 3 there is a control panel 10, on which f. eg. the speed of the machine is displayed and from which it is possible to intervene in the machine control.

Alle på trykmaskinens enkelte komponenter, såsom trykværker og arkpålægger samt -udlægger, aftastede signa-10 ler, som f.eks. den indstillede farveprofil, fugtprofil, ark-gennemløbet eller registerindstillingen, tilføres en som totalelektronik 11 centralt opbygget databehandlings- og styreindretning via en signalledning 21 til informationsbehandling. Samtidig føres via denne signal-15 ledning fra totalelektronikken 11 til de enkelte komponenter i trykmaskinen signaler, der er direkte krævet til overvågning af trykmaskinen. Via en signalledning 22 til effektstyring fremføres fra en i totalelektronikken 11 værende effektelektronik 14 såvel styresig-20 naler til elektriske indstillingsorganer i trykmaskinens komponenter som drivenergi til hoved- og hjælpedrev på trykmaskinen. Totalelektronikken 11 er desuden forbundet via en dataledning 25 med en trykpladelæser 12 og via en dataledning 24 med en kvalitetskontrol 13, 25 som foretager en densitometrisk udmåling af trykarket. Totalelektronikken 11 er via en dataledning 26 forbundet med en styrepult 15. Denne styrepult 15 omfatter i et første område indtastningsorganer og et display 17 til styring af farvestyringen 19 og i et andet om-30 råde indtastningsorganer og et display 18 til maskin-styring 16. Det er naturligvis også muligt at sammenfatte begge områder og gennemføre maskin- og farvesty-ringen via ét display og én indtastningspult. Som figuren viser, er der på trykmaskinen ingen yderligere eller 35 databehandlende kredsløb eller indretninger; de indtil nu normalt mange over trykmaskinen fordelte elektriske 8 DK 167481 B1 kredsløb er samlet i totalelektronikken 11. Denne elektronik 11 er ikke blot en simpel samling af de hidtil anvendte komponenter, men muliggør som følge af integrationen af disse komponenter en optimeret regulering el-5 ler styring af trykningsforløbet. Desuden er der en dataledning 20 kaldet ekstern, med hvilken der kan tilføres trykmaskinen informationer, f.eks. fra en arbejds-forberedelsesstation. Gennem denne dataledning kan f.eks. alle indstillingsværdier for indstillingsorganer-10 ne overføres til forindstilling af trykmaskinen. Ligeledes kan opgavespecifikke data, som f.eks. antallet af tryk, der skal fremstilles, tilføres trykmaskinen eller styrepulten 15. Ligeledes er det muligt via denne dataledning 20 at få uddata, der er specifikke for 15 trykmaskinen. Til forberedelse af en trykning kan der f.eks. via totalelektronikken foretages en målrettet forindfarvning af farveværket. Ligeledes er det muligt at funktionsafprøve indstillingsorganerne og sensorerne. Yderligere er der mulighed for ved hjælp af totalelek-20 tronikken 11 at foretage en overvågning af sliddet af slidfølsomme dele af trykmaskinen og at afgive advarselssignaler ved overskridelse af bestemte grænseværdier.All signals on the printing machine's individual components, such as printing works and sheets, as well as a plotter, are scanned signals, such as e.g. the set color profile, moisture profile, sheet throughput or register setting, a central processing data processing and control device is supplied as a central electronics 11 via an information processing signal line 21. At the same time, via this signal line 15 from the total electronics 11, to the individual components of the printing machine, signals are directly required for monitoring the printing machine. Via a signal line 22 for power control, power electronics 14 present in the total electronics 11 are supplied with both control signals for electrical adjusting means in the components of the printing machine as well as drive energy for main and auxiliary drives on the printing machine. In addition, the total electronics 11 are connected via a data line 25 to a printing plate reader 12 and via a data line 24 with a quality control 13, 25 which performs a densitometric measurement of the printing sheet. The total electronics 11 are connected via a data line 26 to a control desk 15. This control desk 15 comprises, in a first area, input means and a display 17 for controlling the color control 19, and in a second area input means and a display 18 for machine control 16. Of course, it is also possible to summarize both areas and implement the machine and color control via one display and one input desk. As the figure shows, there are no additional or data processing circuits or devices on the printing machine; The electrically distributed electrical circuits used up to now many 8 DK 167481 B1 circuits are assembled in the total electronics 11. This electronics 11 is not only a simple assembly of the components used so far, but as a result of the integration of these components enables an optimized control el-5 manages control of the printing process. In addition, there is a data line 20 called external, with which information can be supplied to the printing machine, e.g. from a work-preparation station. Through this data line, e.g. all setting values for the setting means are transmitted to the presetting of the printing machine. Similarly, task-specific data, such as the number of pressures to be produced is supplied to the printing machine or control desk 15.
