Definitions
- the invention relates to a method for changing the relative humidity of a printing material by means of a drying unit comprising a number of drying elements, which are arranged transversely to the transport direction of the printing substrate and are directed to the printing material to dry each with a drying intensity, wherein the drying elements can be controlled individually and a moistening device comprising a number of moistening elements, which are arranged transversely to the transport direction of the printing substrate and are directed to the substrate to moisten each with a moisture amount, the moistening elements can be controlled individually.
- this leads to the problem that the paper is either extreme behaves differently with respect to the electrostatics or is very wavy.
- drying units which dry the printing material by means of heating elements are therefore used in the prior art.
- drying unit for a printing material web.
- a number of drying elements is provided, which are positioned transversely to the printing material web.
- Each of these drying elements comprises a heating element to heat the ambient air and a fan, which directs the warm air in the direction of the printing material.
- the printing material which is guided past the drying unit, even or the color can be dried.
- For a uniform drying temperature across the web width sensors are provided in the drying elements that measure the air temperature. These data are used to adjust the speed of the individual drying elements in such a way that a uniform temperature distribution and thus drying is made possible.
- Such a device can not prevent the printing material web or the pressure after drying has a non-uniform moisture distribution.
- Such a device thus results in that in the case of unequal humidity, although the areas of high humidity can be dried, but at the same time the areas of not so high or normal humidity (about 2% to 5% relative humidity) due to missing Solvent / water order to be dried out more strongly, so that the residual moisture of the paper drops to, for example, below 2% relative humidity.
- such dry paper also has unfavorable mechanical properties because it is very brittle and stiff, and thus can also be processed poorly.
- the invention is therefore in particular based on the publication US 2014/366760 A1
- the object of the invention to provide a method for changing the relative humidity of a substrate of the type mentioned above, which allows a very uniform manner a particularly uniform drying of the printing material or the printing, so that one for the printing material and the further processing optimal and uniform degree of drying is achieved with a desired residual moisture.
- This object is achieved according to the invention by controlling at least two drying elements in such a way that at least two regions are applied transversely to the transport direction of the printing material with a different drying intensity and at least two moistening elements are controlled such that at least two regions transverse to the transport direction of the printing substrate with a different moisture quantity be charged.
- the invention is based on the consideration that the entry of solvent / water is dependent on the application of paint. Since the color is not applied evenly, the moisture is not evenly distributed on the substrate, but changes both in printing material direction and across it and is usually inhomogeneous in both directions. It was recognized that with the same drying time the areas of high humidity had to be dried more, as the areas of lower humidity and the areas of lower humidity must be moistened before or after drying accordingly stronger. For this reason, the plurality of drying elements or moistening elements arranged transversely to the printing material direction are adjusted in such a way that the drying intensity, ie the temperature provided for drying or moistening intensity, ie the amount of moisture, varies. In this case, at least two regions or zones are provided transversely to the printing material direction, which are acted upon by a different drying or moistening intensity.
- the drying elements or the moistening elements are controlled on the basis of measured data of a sensor unit in a particularly preferred embodiment.
- the relative humidity of the printing material is determined in a preferred embodiment.
- the sensor unit may also consist of a number of sensor elements which are arranged transversely to the transport direction of the printing material. The sensor elements measure the relative humidity of a single area of the substrate.
- a control unit can then, based on the measurement data of each individual area, control the drying or moistening element assigned to this area and determine the optimum drying intensity or moisture quantity so that the printing material web then has a substantially constant distribution of the relative humidity transversely to the transport direction.
- the waviness of the web can also be detected and from it the moisture can be indirectly determined. Since the solvent / water entry in the inkjet process depends on the subject, the locations of high humidity are to be equated with those of a high color occupancy. Thus, as sensor elements and optical sensors for detecting the locations of different color assignment can be used.
- the areas of high humidity can also be found in the print data or Vorgenaries be generated because places with high color occupancy a high humidity order, places with medium color occupancy of a medium humidity order and places with low color occupancy a lower moisture order, etc. correspond.
- the control of the drying elements or of the moistening elements is carried out on the basis of stored or entered print data or precursor data.
- the printing material speed and the path of the printing material can be taken into account in order to achieve optimally timed control of the drying elements or moistening elements.
- the drying elements or moistening elements are also controlled so that at least two areas are acted upon in the transport direction of the printing material with a different drying intensity or moisture.
- the advantages achieved by the invention are in particular that by the different drying or moistening of individual areas transversely to or in the transport direction of the printing material, which can be compensated in the context of the printing process inhomogeneous relative humidity of the printing material. As a result, a substantially uniform and constant distribution of the relative humidity is achieved. Also, by the individual control of the drying and moistening a desired and optimal for further processing residual moisture of the printing material can be achieved.
- FIG. 1 a drying unit 1 for a printing material web is shown, which reduces the relative humidity of the printing substrate 2 to a desired, adjustable value.
- the drying unit 1 is specifically designed so that the relative humidity of the printing material web 2 after passing through the printing material web 2 by the drying unit 1 and the width B of the printing substrate 2 has a substantially constant value.
- the drying unit 1 after the FIG. 1 a sensor unit 6 in the form of a sensor strip whose measuring range extends over the entire width B of the printing material web 2 and the relative humidity or another measured variable from which the relative humidity of the printing material web 2 can be determined directly or indirectly.
- the sensor unit 6 according to the embodiment of FIG. 1 and FIG. 2 In this case, it comprises a multiplicity of sensor elements 8 arranged next to one another, each of which measures a defined section of the printing material web 2.
- the sensor unit 6 may also comprise a single sensor element 8 or a number of sensor elements 8, which are or arranged transversely to the transport direction x of the printing substrate 2 traversing.
- the sensor unit 6 is connected to an evaluation unit 10 via a data line 12, via which the measurement data of the sensor elements 8 are sent to the evaluation unit 10 and control commands can also be sent to the sensor unit 6 by the evaluation unit 10 or a control module, not shown ,
- the evaluation unit 10 generates from the measured data a profile of the relative humidity of the printing material web 2 across the width B of the printing material web 2 and determines from these values an optimal setting for the drying strip 4 in order to achieve the desired relative residual moisture of the printing substrate web B.
- the drying bar 4 also comprises a number of drying elements 14 arranged side by side and substantially over the entire width B of the printing material web 2 are and are designed such that they lower the relative humidity of the printing substrate 2 in a respective associated area.
- Each of these drying elements 12 can be controlled individually and the drying intensity can be adjusted individually, so that the desired target profile of the relative humidity can be achieved by controlling the drying elements 12 in an optimum manner from the determined actual profile of the relative humidity of the printing material web 2.
- the drying bar on the data side is also connected via a data line 16 to the evaluation unit 10 or a control module, not shown, of the evaluation unit 10 in order to transmit control commands to the individual drying elements 12.
- the drying unit 1 may also comprise a moistening strip 18. Such a configuration of the drying unit 1 is in FIG. 2 shown.
- the moistening strip 18 also comprises a number of adjacent moistening elements 20, which are arranged substantially over the entire width B of the printing material web 2 and can moisten the printing material web 2 in a respectively assigned area, so that the relative humidity of the printing substrate web 2 is increased.
- This humidification unit 18 is also connected on the data side to the evaluation unit 10 via a data line 22 so that control signals from the evaluation unit 10 or a control module, not shown, of the evaluation unit can be transmitted to the humidification strip 18.
- the printing material web is not lowered or dried to a relative humidity substantially constant over the width B of the printing material web 2, but rather the moisture content of the substrate Printing material web 2 is increased in individual areas, so that a uniform distribution of the relative humidity is achieved.
- a drying bar 24 is provided to reduce the relative humidity of the printing material to the desired target value. This drying bar 24 can also be as in FIG. 1 illustrated include a number of individually controllable drying elements 14.

Description
Die Erfindung betrifft ein Verfahren zur Änderung der relativen Feuchte eines Bedruckstoffs mittels einer Trocknungseinheit, die eine Anzahl von Trocknungselementen umfasst, die quer zur Transportrichtung des Bedruckstoffs angeordnet sind und auf den Bedruckstoff gerichtet sind, um diesen jeweils mit einer Trocknungsintensität zu trocknen, wobei die Trocknungselemente einzeln angesteuert werden können und einer Befeuchtungseinrichtung, die eine Anzahl von Befeuchtungselementen umfasst, die quer zur Transportrichtung des Bedruckstoffs angeordnet sind und auf den Bedruckstoff gerichtet sind, um diesen jeweils mit einer Feuchtigkeitsmenge zu befeuchten, wobei die Befeuchtungselemente einzeln angesteuert werden können.The invention relates to a method for changing the relative humidity of a printing material by means of a drying unit comprising a number of drying elements, which are arranged transversely to the transport direction of the printing substrate and are directed to the printing material to dry each with a drying intensity, wherein the drying elements can be controlled individually and a moistening device comprising a number of moistening elements, which are arranged transversely to the transport direction of the printing substrate and are directed to the substrate to moisten each with a moisture amount, the moistening elements can be controlled individually.
Bei Digitaldruckmaschinen, die insbesondere nach dem Inkjet-Druckverfahren arbeiten, werden mit der Farbe relativ hohe Mengen an Flüssigkeit auf den Bedruckstoff aufgetragen und dringen in diesen ein, was insbesondere bei größeren Einträgen von Wasser als Lösemittel der Druckfarbe in Papier zu Problemen führen kann. Dabei sind insbesondere die Ausdehnung des Papiers sowohl in Längsrichtung als auch quer zur Faserrichtung, das Bilden von sogenannten Wassersäcken, d.h. durch die Dehnung verursachte Längung und die Veränderung der mechanischen Eigenschaften des Papiers zu beachten. Dies führt im Laufe der weiteren Verarbeitung des Bedruckstoffs zu Problemen und damit auch Qualitätseinbußen im Endprodukt und beispielsweise zum Verwerfen des Bedruckstoffs bei einem in Bedruckstoffrichtung gesehenen asymmetrischen bzw. ungleichen Farbauftrag aufgrund von sehr hoher Welligkeit des Papiers.In digital printing machines, which operate in particular by the inkjet printing process, relatively high amounts of liquid are applied to the substrate with the ink and penetrate into this, which can lead to problems especially with larger inputs of water as a solvent of the printing ink in paper. In particular, the expansion of the paper both in the longitudinal direction and transverse to the fiber direction, the formation of so-called water bags, i. elongation caused by the elongation and the change in mechanical properties of the paper must be taken into account. This leads in the course of further processing of the printing material to problems and thus also quality losses in the final product and, for example, discarding of the printing substrate at a printing material direction seen asymmetric or uneven ink application due to very high waviness of the paper.
Durch die Feuchtigkeit kann sowohl der Druckprozess als auch der nachgeschaltete Nachverarbeitungsprozess beeinflusst werden. In der Nachverarbeitung führt dies beispielsweise zu der Problematik, dass sich das Papier entweder extrem unterschiedlich bezüglich der Elektrostatik verhält oder sehr wellig ist. Es kann aber auch ein Problem sein, dass aufgrund der teilweise hohen Feuchtigkeit des Papiers keine Elektrostatik beispielsweise zum Verblocken aufeinander liegender Blätter oder Signaturen verwendet werden, da die Elektrostatik bei höherer Bedruckstoffdichte abgeführt wird.Moisture can influence both the printing process and the downstream post-processing process. In post-processing, for example, this leads to the problem that the paper is either extreme behaves differently with respect to the electrostatics or is very wavy. However, it can also be a problem that due to the sometimes high moisture content of the paper, no electrostatics are used, for example, to block overlapping sheets or signatures, since the electrostatics are removed at a higher substrate density.
Um die Feuchtigkeit des Bedruckstoffs zu reduzieren, werden im Stand der Technik daher Trocknungseinheiten eingesetzt, die mittels Heizelementen den Bedruckstoff trocknen.In order to reduce the moisture content of the printing material, drying units which dry the printing material by means of heating elements are therefore used in the prior art.
Aus der Druckschrift
Eine derartige Vorrichtung kann allerdings nicht verhindern, dass die Bedruckstoffbahn bzw. der Druck auch nach der Trocknung eine ungleichmäßige Feuchtigkeitsverteilung aufweist. Je nach Ausgangsfeuchte kann es dabei allerdings auch bei der Druckschrift
Aus den Druckschriften
Der Erfindung liegt daher insbesondere ausgehend von der Druckschrift
Diese Aufgabe wird erfindungsgemäß gelöst, indem mindestens zwei Trocknungselemente derart angesteuert werden, dass mindestens zwei Bereiche quer zur Transportrichtung des Bedruckstoffs mit einer unterschiedlichen Trocknungsintensität beaufschlagt werden und mindestens zwei Befeuchtungselemente derart angesteuert werden, dass mindestens zwei Bereiche quer zur Transportrichtung des Bedruckstoffs mit einer unterschiedlichen Feuchtigkeitsmenge beaufschlagt werden.This object is achieved according to the invention by controlling at least two drying elements in such a way that at least two regions are applied transversely to the transport direction of the printing material with a different drying intensity and at least two moistening elements are controlled such that at least two regions transverse to the transport direction of the printing substrate with a different moisture quantity be charged.
Die Erfindung geht von der Überlegung aus, dass der Eintrag von Lösemittel/Wasser vom Farbauftrag abhängig ist. Da auch die Farbe nicht gleichmäßig aufgetragen wird, ist auch die Feuchtigkeit nicht gleichmäßig auf den Bedruckstoff verteilt, sondern verändert sich sowohl in Bedruckstoffrichtung als auch quer dazu und ist üblicherweise in beiden Richtungen inhomogen. Es wurde dabei erkannt, dass bei gleicher Trocknungsdauer die Bereiche hoher Feuchtigkeit stärker getrocknet werden müssen, als die Bereiche geringerer Feuchtigkeit und die Bereiche geringerer Feuchtigkeit vor oder nach dem Trocknen entsprechend stärker befeuchtet werden müssen. Aus diesem Grund werden die mehreren quer zur Bedruckstoffrichtung angeordneten Trocknungselemente oder Befeuchtungselemente derart eingestellt, dass die Trocknungsintensität, also die bereitgestellte Temperatur zur Trocknung, bzw. Befeuchtungsintensität, also die Feuchtigkeitsmenge, variiert. Dabei sind mindestens zwei Bereiche bzw. Zonen quer zur Bedruckstoffrichtung vorgesehen, die mit einer unterschiedlichen Trocknungs- bzw. Befeuchtungsintensität beaufschlagt werden.The invention is based on the consideration that the entry of solvent / water is dependent on the application of paint. Since the color is not applied evenly, the moisture is not evenly distributed on the substrate, but changes both in printing material direction and across it and is usually inhomogeneous in both directions. It was recognized that with the same drying time the areas of high humidity had to be dried more, as the areas of lower humidity and the areas of lower humidity must be moistened before or after drying accordingly stronger. For this reason, the plurality of drying elements or moistening elements arranged transversely to the printing material direction are adjusted in such a way that the drying intensity, ie the temperature provided for drying or moistening intensity, ie the amount of moisture, varies. In this case, at least two regions or zones are provided transversely to the printing material direction, which are acted upon by a different drying or moistening intensity.
Für eine optimale Trocknung des Bedruckstoffs bzw. eine möglichst konstante Restfeuchtigkeit des Bedruckstoffs wird in besonders bevorzugter Ausführung die Steuerung der Trocknungselemente bzw. der Befeuchtungselemente auf Basis von Messdaten einer Sensoreinheit vorgenommen. Dabei wird in bevorzugter Ausgestaltung die relative Feuchte des Bedruckstoffs bestimmt. Dabei kann die Sensoreinheit ebenfalls aus einer Anzahl von Sensorelementen bestehen, die quer zur Transportrichtung des Bedruckstoffs angeordnet sind. Die Sensorelemente messen dabei die relative Feuchte eines einzelnen Bereiches des Bedruckstoffs. Eine Steuereinheit kann anschließend auf Basis der Messdaten jedes einzelnen Bereiches, das diesen Bereich zugeordneten Trocknungs- oder Befeuchtungselement ansteuern und die optimale Trocknungsintensität bzw. Feuchtigkeitsmenge bestimmen, damit die Bedruckstoffbahn anschließend quer zur Transportrichtung eine im Wesentlichen konstante Verteilung der relativen Feuchte aufweist.For optimal drying of the printing substrate or a residual moisture of the printing material which is as constant as possible, the drying elements or the moistening elements are controlled on the basis of measured data of a sensor unit in a particularly preferred embodiment. In this case, the relative humidity of the printing material is determined in a preferred embodiment. In this case, the sensor unit may also consist of a number of sensor elements which are arranged transversely to the transport direction of the printing material. The sensor elements measure the relative humidity of a single area of the substrate. A control unit can then, based on the measurement data of each individual area, control the drying or moistening element assigned to this area and determine the optimum drying intensity or moisture quantity so that the printing material web then has a substantially constant distribution of the relative humidity transversely to the transport direction.
Neben der Sensoreinheit zur Messung der relativen Feuchte, kann auch die Welligkeit der Bahn detektiert werden und aus ihr die Feuchtigkeit indirekt bestimmt werden. Da beim Inkjet-Verfahren der Lösemittel-/Wasser-Eintrag vom Sujet abhängig ist, sind die Stellen hoher Feuchtigkeit mit den Stellen einer hohen Farbbelegung gleichzusetzen. Somit können als Sensorelemente auch optische Sensoren zur Erfassung der Stellen unterschiedlicher Farbbelegung zum Einsatz kommen.In addition to the sensor unit for measuring the relative humidity, the waviness of the web can also be detected and from it the moisture can be indirectly determined. Since the solvent / water entry in the inkjet process depends on the subject, the locations of high humidity are to be equated with those of a high color occupancy. Thus, as sensor elements and optical sensors for detecting the locations of different color assignment can be used.
Aufgrund des direkten Zusammenhangs zwischen Farbbelegung und Feuchtigkeit bzw. Feuchtigkeitseintrag können die Bereiche hoher Feuchtigkeit auch aus den Druckdaten bzw. Vorstufendaten generiert werden, da Stellen mit hoher Farbbelegung einem hohen Feuchtigkeitsauftrag, Stellen mit mittlerer Farbbelegung einem mittleren Feuchtigkeitsauftrag und Stellen mit geringer Farbbelegung einem geringeren Feuchtigkeitsauftrag etc. entsprechen. Aus diesem Grund wird in alternativer oder zusätzlicher vorteilhafter Ausgestaltung die Steuerung der Trocknungselemente bzw. der Befeuchtungselemente auf Basis von hinterlegten oder eingegebenen Druckdaten oder Vorstufendaten vorgenommen. Dabei kann zusätzlich die Bedruckstoffgeschwindigkeit und der Weg des Bedruckstoffs berücksichtigt werden, um eine zeitlich optimal abgestimmte Steuerung der Trocknungselemente bzw. Befeuchtungselemente zu erreichen.Due to the direct relationship between ink coverage and moisture or moisture penetration, the areas of high humidity can also be found in the print data or Vorstufendaten be generated because places with high color occupancy a high humidity order, places with medium color occupancy of a medium humidity order and places with low color occupancy a lower moisture order, etc. correspond. For this reason, in an alternative or additional advantageous embodiment, the control of the drying elements or of the moistening elements is carried out on the basis of stored or entered print data or precursor data. In addition, the printing material speed and the path of the printing material can be taken into account in order to achieve optimally timed control of the drying elements or moistening elements.
Um eine Veränderung der Farbbelegung in Transportrichtung des Bedruckstoffs zu berücksichtigen, werden in bevorzugter Ausführung die Trocknungselemente bzw. Befeuchtungselemente auch derart angesteuert, dass mindestens zwei Bereiche in Transportrichtung des Bedruckstoffs mit einer unterschiedlichen Trocknungsintensität bzw. Feuchtigkeitsmenge beaufschlagt werden.In order to take into account a change in the ink coverage in the transport direction of the printing material, in a preferred embodiment, the drying elements or moistening elements are also controlled so that at least two areas are acted upon in the transport direction of the printing material with a different drying intensity or moisture.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch die unterschiedliche Trocknung bzw. Befeuchtung einzelner Bereiche quer zur oder auch in Transportrichtung des Bedruckstoffs, die im Rahmen des Druckprozesses inhomogene relative Feuchte des Bedruckstoffs ausgeglichen werden kann. Dadurch wird eine im Wesentlichen gleichmäßige und konstante Verteilung der relativen Feuchte erreicht. Auch kann durch die individuelle Steuerung der Trocknungs- und Befeuchtungselemente eine gewünschte und für die weitere Verarbeitung optimale Restfeuchtigkeit des Bedruckstoffs erreicht werden.The advantages achieved by the invention are in particular that by the different drying or moistening of individual areas transversely to or in the transport direction of the printing material, which can be compensated in the context of the printing process inhomogeneous relative humidity of the printing material. As a result, a substantially uniform and constant distribution of the relative humidity is achieved. Also, by the individual control of the drying and moistening a desired and optimal for further processing residual moisture of the printing material can be achieved.

Die Trocknungsleiste 4 umfasst dazu ebenfalls eine Anzahl von Trocknungselementen 14, die nebeneinander und im Wesentlichen über die gesamte Breite B der Bedruckstoffbahn 2 angeordnet sind und derart ausgebildet sind, dass sie die relative Feuchte der Bedruckstoffbahn 2 in einem jeweils zugeordneten Bereich senken.
