Description
Die Erfindung betrifft ein Inkjet-Drucksystem für eine nach dem Offset-Druckprinzip arbeitende Druckmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an inkjet printing system for a printing press operating on the offset printing principle according to the preamble of
In nach dem Offset-Druckprinzip arbeitende Druckmaschinen, insbesondere in Rollenrotationsdruckmaschinen, finden zunehmend Inkjet-Druckeinrichtungen Verwendung, die vorzugsweise der Individualisierung von über den Offsetdruck hergestellten Druckerzeugnissen, wie z.B. Adressendruck, Barcodes, Nummerierungen oder sonstigen Markierungen, dienen. Derartige Inkjet-Drucksysteme verfügen über mind. einen Inkjet-Druckkopf, der nach dem sog. Continuous-Inkjet-Prinzip, dem Drop-On-Demand-Inkjet-Prinzip, dem Thermal-Inkjet-Prinzip, dem Bubble-Inkjet-Prinzip oder jedem anderen Inkjet-Prinzip ausgebildet sein kann. Die Inkjet-Druckköpfe verfügen üblicherweise über eine Düsenreihe aus mehreren nebeneinander angeordneten Düsen, über die Druckfarben auf einen zu bedruckenden Bedruckstoff, wie z.B. einer Papierbahn gerichtet werden kann.In printing presses operating according to the offset printing principle, in particular in web-fed rotary printing presses, use is increasingly being made of inkjet printing devices, which are preferably used for the individualization of printed products produced by offset printing, e.g. Address printing, barcodes, numbering or other markings. Such inkjet printing systems have at least. An inkjet printhead, the so-called. Continuous inkjet principle, the drop-on-demand inkjet principle, the thermal inkjet principle, the bubble inkjet principle or any other inkjet principle can be formed. The inkjet printheads usually have a nozzle row of a plurality of juxtaposed nozzles, via the inks on a printing substrate, such. a paper web can be addressed.
Meistens befinden sich derartige Inkjet-Drucksysteme in der Nachverarbeitung von Druckproduktionslinien, da dort die Druckgeschwindigkeit wesentlich geringer ist als die Prozessgeschwindigkeit im Rotationsdruck. Dies hat aber den Nachteil, dass die Einsatzmöglichkeit des zusätzlichen Drucks auf einen kleinen Bereich auf der Außenseite des Druckerzeugnisses beschränkt bleibt.In most cases, such inkjet printing systems are in the post-processing of print production lines, since there the printing speed is much lower than the process speed in the rotary printing. However, this has the disadvantage that the possibility of using the additional pressure is limited to a small area on the outside of the printed product.
Die Inkjet-Technologie ist nach dem Stand der Technik sowohl in privaten Bereichen als auch in industriellen Bereichen (digitale proof-Systeme, die direkt den Datenbestand der EDV nutzen / Digital-Drucker) weit verbreitet.The inkjet technology is widely used in the state of the art both in private areas as well as in industrial areas (digital proof systems, which directly use the data of the computer / digital printer).
Für die Bereiche der Druckindustrie gibt es bereits vorhandene Inkjet-Drucksysteme. Es werden Inkjet-Systeme zur Herstellung von Andruckersatz (proofs) zur Bebilderung von Druckplatten bzw. Druckformen oder explizit für den Digitaldruck von kleinen speziellen Auflagen (z.B. Körperformendruck) und spezielle Formate (z.B. großformatige Plakate oder Textilien) eingesetzt. Ähnlich wie beim privaten Einsatz des Inkjet-Drucks gilt auch für den industriellen Einsatz, dass Inkjet-Drucksysteme vorwiegend für sehr kleine Druckauflagen genutzt werden und dass die Kosten für Drucktinten sehr hoch sind. Im Vergleich zu konventionellen Druckverfahren wie eben Offset ist der Inkjetdruck für den Auflagendruck nicht wirtschaftlich, da dieser bei hohen Druckauflösungen sehr langsam ist.There are already existing inkjet printing systems for the areas of the printing industry. There will be inkjet systems for the production of pressure equipment (proofs) for imaging of printing plates or printing plates or explicitly for the digital printing of small special editions (eg body shape printing) and special formats (eg large format posters or textiles) used. Similar to the private use of inkjet printing, industrial inkjet printing systems are primarily used for very short print runs and the cost of printing inks is very high. Compared to conventional printing processes such as offset, the inkjet printing for the print run is not economical because it is very slow at high print resolutions.
Des Weiteren ist beispielsweise aus der
Die Aufgabe der vorliegenden Erfindung besteht nun darin, für eine nach dem Offset-Druckprinzip arbeitende Druckmaschine zu ermöglichen, dass zusätzliche, auch variable Informationen sowie während einer Druckauflage öfters wechselnde Informationen an einer beliebigen Stelle innerhalb des Druckerzeugnisses hinzugefügt werden können.The object of the present invention is therefore to make it possible for a printing press operating according to the offset printing principle that additional, variable information as well as frequently changing information during a print run can be added at any point within the printed product.

Vorstellbar wäre auch ein Einsatz der erfindungsgemäßen Zusatzeinrichtung bereits vor dem entsprechenden Druckwerk in der Druckmaschine.It would also be conceivable to use the additional device according to the invention before the corresponding printing unit in the printing press.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ein besonders bevorzugtes Ausführungsbeispiel der Erfindung wird, ohne hierauf beschränkt zu sein, anhand der Zeichnung näher erläutert.Preferred embodiments of the invention will become apparent from the dependent claims and the description below. A particularly preferred embodiment of the invention will be explained in more detail, without being limited to this, with reference to the drawing.
Inkjet-Druck ist eine Drucktechnologie, die in die Kategorie der Non-Impact-Drucker gehört. Man versteht darunter ein berührungsloses Druckverfahren, bei dem eine winzige Menge Tinte aus einer oder mehreren, extrem kleinen Düsen elektronisch gesteuert (wie beispielsweise in der
Des Weiteren kann das Inkjet-Druckverfahren wie bereits erwähnt digital über so genannte Druckbilddaten angesteuert werden. Somit wäre das Druckbild variabel gestaltbar.Furthermore, as already mentioned, the inkjet printing process can be controlled digitally via so-called print image data. Thus, the print image would be variable shaped.
Der Erfindungsvorschlag hat gegenüber dem Stand der Technik den Vorteil, dass eine Inkjet-Anlage bereits direkt in die Offset-Druckmaschine integriert ist und an verschiedenen Stellen, an verschiedenen Papierbahnen der Druckmaschinen montiert bzw. umgesetzt werden kann. Dadurch kann eben zusätzliche, auch variable Information, sowie während einer Druckauflage öfters wechselnde Information an einer beliebigen Stelle innerhalb des Druckerzeugnisses hinzugefügt werden.The proposed invention has the advantage over the prior art that an inkjet system is already integrated directly into the offset printing press and can be mounted or implemented at various points on different paper webs of the printing presses. As a result, it is possible to add additional information, even variable information, as well as frequently changing information at any point within the printed product during a print run.
