Weiterhin betrifft die Erfindung ein Verfahren zum Vorbehandeln und Bedrucken von textilen OberflƤchen nach dem Oberbegriff des Anspruchs 8.Furthermore, the invention relates to a method for pretreating and printing textile surfaces according to the preamble of claim 8.

Bei einem solchen Verfahren wird ein Textil mittels einer Vorbehandlungseinrichtung vor einem Bedrucken vorbehandelt, wobei ein Vorbehandlungsfluid in einem Vorbehandlungsbereich aufgebracht wird, bedruckt eine Druckeinrichtung, mit mindestens einem Druckkopf, das Textil in dem Vorbehandlungsbereich mit einem Druckbild, steuert eine programmierbaren Steuereinrichtung die Druckeinrichtung und/oder die Vorbehandlungseinrichtung.In such a method, a textile is pretreated prior to printing by means of a pretreatment device wherein a pretreatment fluid is applied in a pretreatment area, a printing device with at least one print head imprints the textile in the pretreatment area with a print image, a programmable controller controls the printing device and / or or the pre-treatment device.

Eine gattungsgemƤƟe Vorrichtung und ein entsprechendes Verfahren zum Vorbehandeln und Bedrucken von textilen OberflƤchen ist zum Beispiel aus der EP 2 481 593 A1 bekannt. Bei dieser Vorrichtung und dem entsprechenden Verfahren ist eine Benetzungszusammensetzung vorgesehen, mittels welcher eine zu bedruckende textile OberflƤche vorbehandelt wird, um in einem zweiten Schritt ein Druckbild auf die vorbehandelte textile OberflƤche aufzutragen. Hierbei wird die VorbehandlungsflĆ¼ssigkeit flƤchig auf einer Druckseite des zu bedruckenden Textils aufgetragen.A generic device and a corresponding method for pretreating and printing textile surfaces is for example from EP 2 481 593 A1 known. In this apparatus and the corresponding method, a wetting composition is provided, by means of which a textile surface to be printed is pretreated, in order to apply a printed image to the pretreated textile surface in a second step. Here, the pretreatment liquid is applied flat on a printing side of the textile to be printed.

Die Chemikalien einer Benetzungszusammensetzung sollen einerseits verhindern, dass Farbtrƶpfchen, welche durch eine Druckeinrichtung auf das Textil aufgetragen werden, durch KapillarkrƤfte sowie andere physikalische und/oder chemische Prozesse in den Fasern des Textils verlaufen, was eine UnschƤrfe des Druckbilds bewirken kann. Somit kann eine erste Funktion der Benetzungszusammensetzung darin bestehen, die StabilitƤt des Druckbildes auf der textilen OberflƤche zu gewƤhrleisten.On the one hand, the chemicals of a wetting composition are intended to prevent color droplets which are applied to the textile by a printing device from passing through capillary forces and other physical and / or chemical processes in the fibers of the textile, which may cause blurring of the printed image. Thus, a first function of the wetting composition may be to ensure the stability of the printed image on the textile surface.

Andererseits sollen die verwendeten Chemikalien des Vorbehandlungsfluids die BindungsfƤhigkeit der auf das Textil aufgetragenen Farbtrƶpfchen an die Fasern des Gewebes positiv beeinflussen und somit die Bindung des Druckbilds an die textile OberflƤche an der vorgesehenen Position auf dem Textil stƤrken und beschleunigen.On the other hand, the chemicals used in the pretreatment fluid should positively affect the binding ability of the paint droplets applied to the textile to the fibers of the fabric and thus strengthen and accelerate the bonding of the print image to the textile surface at the intended position on the fabric.

Beispielsweise durch Reaktion des Vorbehandlungsfluids mit dem Gewebe oder mit Trƶpfchen der aufgetragenen Druckerfarbe und/oder durch anschlieƟende chemische oder thermische Behandlung der Druckerfarbe sowie des mit Vorbehandlungsfluid benetzten Textils, kƶnnen die voranstehend beschriebenen Eigenschaften des Vorbehandlungsfluids hervorgerufen und/oder verstƤrkt werden.For example, by reaction of the pretreatment fluid with the fabric or droplets of the ink applied and / or subsequent chemical or thermal treatment of the ink and the pretreatment fluid wetted fabric, the above described properties of the pretreatment fluid may be evoked and / or enhanced.

ƜberschĆ¼ssiges Vorbehandlungsfluid auf dem flƤchig vorbehandelten Textil, welches nicht mit Druckerfarbe in Kontakt kommt, verbleibt hierbei beispielsweise ungenutzt auf dem Textil zurĆ¼ck oder wird in einem anschlieƟenden Waschungsprozess als Abfallprodukt der Umwelt zugefĆ¼hrt.Excess pretreatment fluid on the area pretreated textile, which does not come in contact with ink, this remains, for example, unused on the textile or is supplied in a subsequent washing process as a waste product of the environment.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Vorbehandeln und Bedrucken eines BekleidungsstĆ¼cks sowie ein entsprechendes Verfahren anzugeben, welche es erlauben, den Einsatz von Vorbehandlungsfluid besonders ƶkologisch und verbrauchsmaterialschonend zu gestalten.The invention has for its object to provide a device for pretreatment and printing of a garment and a corresponding method, which allow to make the use of pretreatment fluid particularly ecological and consumption-friendly.

Die Aufgabe wird nach der Erfindung einerseits durch eine Vorrichtung mit den Merkmalen nach Anspruch 1 und andererseits durch ein Verfahren mit den Merkmalen nach Anspruch 8 gelƶst.The object is achieved according to the invention on the one hand by a device with the features of claim 1 and on the other hand by a method having the features of claim 8.

Ein Grundgedanke der Erfindung besteht darin, eine Vorrichtung zum Vorbehandeln und Bedrucken mit einer Vorbehandlungseinrichtung sowie ein entsprechendes Verfahren anzugeben, mittels welcher gezielt solche Bereiche eines Textils mit einem Vorbehandlungsfluid vorbehandelt werden, die anschlieƟend mit Druckerfarbe bedruckt werden. Somit kƶnnen selbst bei komplexen Druckbildern ZwischenrƤume zwischen Motiven und farbfreien Bereichen eines Druckbildes von einer Vorbehandlung ausgenommen werden. Dies kann im Vergleich zu einem flƤchigen Auftragen einen erheblich effizienteren Einsatz von Vorbehandlungsfluid ermƶglichen.A basic idea of the invention is to specify a device for pretreatment and printing with a pretreatment device and a corresponding method by means of which targeted areas of a textile are pretreated with a pretreatment fluid, which are subsequently printed with printing ink. Thus, even with complex print images, spaces between subjects and colorless areas of a print image can be excluded from pretreatment. This may allow a much more efficient use of pretreatment fluid compared to a flat application.

Nach einer Weiterbildung der Erfindung ist es bevorzugt, dass die Vorbehandlungseinrichtung mindestens eine DĆ¼se aufweist, mittels welcher das Vorbehandlungsfluid auf das Textil auftragbar ist, und dass die mindestens eine DĆ¼se mittels der programmierbaren Steuereinrichtung steuerbar ist. Das Vorbehandlungsfluid kann in einem Vorratstank vorgesehen sein, welcher mit der Vorbehandlungseinrichtung Ć¼ber ein Leitungssystem verbunden ist. Die mindestens eine DĆ¼se kann so ausgebildet sein, dass die Durchflussmenge an Vorbehandlungsfluid durch die mindestens eine DĆ¼se der Vorbehandlungseinrichtung durch eine programmierbare Steuereinrichtung anpassbar ist. Somit kann insbesondere eine Unterbrechung des Fluidflusses aus der mindestens einen DĆ¼se ermƶglicht sein, um einen unbehandelten Bereich auf einem Textil vorzusehen.According to a development of the invention, it is preferred that the pretreatment device has at least one nozzle, by means of which the pretreatment fluid can be applied to the textile, and that the at least one nozzle can be controlled by means of the programmable control device. The pretreatment fluid may be provided in a storage tank which communicates with the pretreatment device connected via a line system. The at least one nozzle can be designed such that the flow rate of pretreatment fluid through the at least one nozzle of the pretreatment device can be adjusted by a programmable control device. Thus, in particular, an interruption of the fluid flow from the at least one nozzle may be made possible in order to provide an untreated area on a textile.

Eine zweckmƤƟige Weiterbildung der Erfindung kann darin bestehen, dass die Vorbehandlungseinrichtung Ć¼ber die gesamte Breite des Textils ausgebildet ist. Dies kann sich vorteilhaft auf die Vorbehandlungsgeschwindigkeit auswirken, da so ein laterales Verfahren der Vorbehandlungseinrichtung entlang der Breite des Textils nicht erforderlich ist, um den Vorbehandlungsbereich auf dem Textil mit Vorbehandlungsfluid zu benetzen. Eine quer zur Verfahrrichtung des Textils unbeweglich vorgesehene Vorbehandlungsvorrichtung kann geringerem VerschleiƟ unterliegen, als vergleichbare quer zur Verfahrensrichtung bewegliche Vorbehandlungseinrichtungen.An expedient development of the invention may consist in that the pretreatment device is formed over the entire width of the textile. This can have an advantageous effect on the pretreatment rate, since such a lateral process of the pretreatment device along the width of the textile is not required in order to wet the pretreatment area on the textile with pretreatment fluid. A pretreatment device immovable transversely to the direction of travel of the textile may be subject to less wear than comparable pretreatment devices which are movable transversely to the direction of the method.

Eine besonders bevorzugte Weiterbildung der Erfindung kann darin bestehen, dass die Vorbehandlungseinrichtung eine Vielzahl von DĆ¼sen aufweist, wobei die DĆ¼sen durch die programmierbare Steuereinrichtung individuell steuerbar sind. Insbesondere kann die Vielzahl von DĆ¼sen Ć¼ber die gesamte Breite des Textils an der Vorbehandlungseinrichtung vorgesehen sein. DĆ¼sen, welche voneinander unabhƤngig durch die programmierbare Steuereinrichtung wƤhrend des Auftragens von Vorbehandlungsfluid zumindest zeitweise verschlieƟbar sind, kƶnnen in besonders vorteilhafter Weise das Vorsehen eines individuellen Vorbehandlungsbereichs auf mindestens einem Teilbereich der Druckseite des Textils ermƶglichen, indem mindestens ein Bereich der Druckseite von der Vorbehandlung ausgenommen bleiben kann. Hierbei kann das Textil auf der Palette mittels der Verfahrenseinrichtung unter der Vorbehandlungseinrichtung hindurchfĆ¼hrbar sein, wobei die einzelnen DĆ¼sen der Vorbehandlungseinrichtung individuell geƶffnet werden kƶnnen, so dass sie nur dann den Austritt von Vorbehandlungsfluid ermƶglichen, wenn ein Teilbereich des individuellen Vorbehandlungsbereichs der entsprechenden DĆ¼se oder DĆ¼sen zugestellt ist. Auch kann die Vorbehandlungseinrichtung gegenĆ¼ber dem Textil transversal verfahrbar sein, was ein besonders zĆ¼giges und gleichmƤƟiges Vorbehandeln des Textils ermƶglichen kann. Die Steuereinrichtung steuert dabei auch das Verfahren der Palette, welche eine TrƤgereinrichtung fĆ¼r das Textil ist. Die Verfahreinrichtung kann eine Transportkette oder ein Transportband aufweisen.A particularly preferred development of the invention may consist in that the pretreatment device has a plurality of nozzles, wherein the nozzles are individually controllable by the programmable control device. In particular, the plurality of nozzles can be provided over the entire width of the textile at the pretreatment device. Nozzles, which are at least temporarily closed by the programmable controller during the application of pretreatment fluid independently of each other, may advantageously allow the provision of an individual pretreatment area on at least a portion of the print side of the fabric by excluding at least a portion of the print side from the pretreatment can. In this case, the textile can be passed on the pallet by means of the processing device under the pretreatment device, wherein the individual nozzles of the pretreatment device can be opened individually, so that they allow the exit of pretreatment fluid only if a portion of the individual pretreatment area of the corresponding nozzle or nozzles delivered is. Also, the pretreatment device can be moved transversely relative to the textile, which is a particularly rapid and uniform pretreatment of the textile. The control device also controls the process of the pallet, which is a carrier device for the textile. The traversing device may have a transport chain or a conveyor belt.

Eine zweckmƤƟige Weiterbildung der Erfindung kann darin bestehen, dass die Vorbehandlungseinrichtung an einem Eingangsbereich einer Trocknereinrichtung vorgesehen ist, welcher insbesondere als Durchlauftrockner ausgebildet ist. Somit kann das Vorbehandlungsfluid direkt nach dem Auftragen von einem Lƶsemittelanteil befreit werden und/oder einer thermischen Behandlung unterzogen werden. Hierbei ist es besonders bevorzugt, dass die Trocknereinrichtung Ć¼ber die gesamte Breite des Textils ausgebildet ist, was ein gleichmƤƟiges Behandeln des Textils ermƶglichen kann.An expedient development of the invention may consist in that the pretreatment device is provided at an input region of a dryer device, which is designed in particular as a continuous dryer. Thus, the pre-treatment fluid can be freed from a solvent content immediately after application and / or subjected to a thermal treatment. It is particularly preferred that the drying device is formed over the entire width of the textile, which may allow uniform treatment of the textile.

Nach einer Weiterbildung der Erfindung ist es bevorzugt, dass durch die Erkennungseinrichtung eine Lage des Textils auf der Palette ermittelbar ist und dass durch die programmierbare Steuereinrichtung der Vorbehandlungsbereich abhƤngig von der Lage des Textils aufbringbar ist. Somit kann das Textil in einer beliebigen horizontalen Ausrichtung auf der Palette vorsehbar sein, wobei die programmierbare Steuereinrichtung die Vorbehandlungseinrichtung anhand der Informationen der Erkennungseinrichtung steuern kann, um ein individuelles Benetzen des Vorbehandlungsbereichs mit Vorbehandlungsfluid zu ermƶglichen und den Vorbehandlungsbereich auf dem Textil so auszurichten, dass das Druckbild die gewĆ¼nschte Orientierung auf dem Textil aufweist. Hierzu kann die Erkennungseinrichtung die Ausrichtung beispielsweise anhand einer Markierung oder der Textilstruktur ermitteln.According to a development of the invention, it is preferred that a position of the textile on the pallet can be determined by the recognition device and that the pretreatment region can be applied by the programmable control device as a function of the position of the textile. Thus, the textile may be providable in any horizontal orientation on the pallet, the programmable controller being able to control the pre-treatment device based on the information from the recognition device to allow for individually wetting the pre-treatment area with pre-treatment fluid and aligning the pre-treatment area on the textile so that the Printed image has the desired orientation on the textile. For this purpose, the recognition device can determine the orientation, for example, based on a marking or the textile structure.

Nach einer Weiterbildung ist es bevorzugt, dass die programmierbare Steuereinrichtung ausgebildet ist, einen von einem Benutzer gesendeten und eindeutig definierten Druckauftrag mit Druck- und Bilddaten zu empfangen, mittels der Erkennungseinrichtung den zu bedruckenden Bereich auf dem Textil zu identifizieren und mittels der Druckeinrichtung ein entsprechendes Druckbild auf dem Textil aufzudrucken. Die programmierbare Steuereinrichtung kann das Textil mittels der Erkennungseinrichtung dem eindeutig definierten Druckauftrag mit Druck- und Bilddaten zuordnen und ein entsprechendes Druckbild mit einer auftragsgemƤƟen Orientierung auf dem Textil vorsehen. Die Druckeinrichtung kann mittels der programmierbaren Steuereinrichtung insbesondere dazu steuerbar sein, in dem zuvor aufgebrachten Vorbehandlungsbereich auf dem Textil das Druckbild vorzusehen.According to a development, it is preferred that the programmable control device is designed to receive a print job and image data sent by a user and clearly defined, to identify the region to be printed on the textile by means of the recognition device and to identify a corresponding print image by means of the printing device to be printed on the textile. The programmable control device can assign the textile by means of the recognition device to the clearly defined print job with print and image data and provide a corresponding print image with an order-oriented orientation on the textile. The printing device can by means of the programmable controller in particular be controllable to provide in the previously applied pre-treatment area on the textile the printed image.

Besonders zweckmƤƟig ist es nach einer Weiterbildung der Erfindung, dass eine digitale Druckeinrichtung mit mindestens einer DruckdĆ¼se auf das vorbehandelte Textil, welches sich auf der Palette befindet, das Druckbild aufdruckt und dass die Druckeinrichtung von der programmierbaren Steuereinrichtung gesteuert ist, wobei das Druckbild individuell auf das erkannte Textil aufgedruckt wird. Mittels digitaler Drucktechnik kann ein Druckbild auf einem Textil in besonders prƤziser Weise vorsehbar sein. Hierzu kann die DruckdĆ¼se mindestens entlang der Breite des vorgesehenen Textils lateral verfahrbar angeordnet sein. Die programmierbare Steuereinrichtung kann Informationen bezĆ¼glich eines vorgesehen Druckbilds, welches auf dem Textil vorgesehen werden soll, an die Druckeinrichtung fĆ¼r ein Bedrucken Ć¼bermitteln. Das auf dem Textil vorzusehende Druckbild sowie weitere Informationen, welche die programmierbare Steuereinrichtung zum Steuern der Vorrichtung benƶtigt, kƶnnen durch einen Benutzer mittels eines Eingabeterminals oder Ć¼ber eine Datenfernleitung an die programmierbare Steuereinrichtung Ć¼bermittelt werden. Es kann zweckdienlich sein, die programmierbare Steuereinrichtung so auszubilden, dass Informationen zu mehreren DruckauftrƤgen, auch durch mehrere Benutzer, in der programmierbaren Steuereinrichtung hinterlegbar sind. Somit kann die programmierbare Steuereinrichtung auch als Datenbank fĆ¼r bereits durchgefĆ¼hrte, erneut abrufbare und ausfĆ¼hrbare sowie zukĆ¼nftige DruckauftrƤge einsetzbar sein. Alternativ kann auch eine separate Datenbank zum Hinterlegen von DruckauftrƤgen vorgesehen sein, welche mit der programmierbaren Steuereinrichtung in Verbindung steht.It is particularly useful according to a development of the invention that a digital printing device with at least one print nozzle on the pretreated textile, which is located on the pallet, the printed image imprints and that the printing device is controlled by the programmable controller, wherein the print image individually on the recognized textile is printed. By means of digital printing technology, a printed image on a textile can be provided in a particularly precise manner. For this purpose, the pressure nozzle can be arranged laterally movable at least along the width of the intended textile. The programmable controller may communicate information regarding a designated print image to be provided on the textile to the printing device for printing. The printed image to be provided on the textile as well as further information required by the programmable control device for controlling the device can be transmitted to the programmable control device by a user by means of an input terminal or via a data transmission line. It may be expedient to design the programmable control device such that information about a plurality of print jobs, even by a plurality of users, can be stored in the programmable control device. Thus, the programmable controller can also be used as a database for already performed, again retrievable and executable as well as future print jobs. Alternatively it can also be provided a separate database for storing print jobs, which is in communication with the programmable controller.

Eine bevorzugte Weiterbildung des erfindungsgemƤƟen Verfahrens kann darin bestehen, dass das Textil mit einer Markierung versehen wird, welche ausgebildet ist, eine Zugehƶrigkeit des Textils zu einem zuvor eindeutig definierten Druckauftrag mit Druck- und Bilddaten anzugeben. Die Markierung kann in Form eines Drucks auf dem Textil vorgesehen sein, wobei die Markierung beispielsweise alle fĆ¼r die DurchfĆ¼hrung des Druckauftrages benƶtigten Informationen enthalten kann oder einen Verweis auf beispielsweise in der programmierbaren Steuereinrichtung hinterlegte Informationen darstellt. Insbesondere kann die Markierung in Form eines Strichcodes, QR-Codes, einer RFID-Markierung oder in einer sonstigen visuellen oder sensorisch erfassbaren AusfĆ¼hrungsform vorgesehen sein.A preferred development of the method according to the invention may be that the textile is provided with a marking which is designed to indicate an affiliation of the textile to a previously clearly defined print job with print and image data. The marking may be provided in the form of a print on the textile, wherein the marking may contain, for example, all the information required for the execution of the print job or represents a reference to, for example, stored in the programmable controller information. In particular, the mark may be in the form of a bar code, Be provided QR codes, an RFID tag or in any other visual or sensory detectable embodiment.

Das Textil 20 ist auf der Palette 22 mittels der Verfahreinrichtung 23 entlang einer FĆ¼hrungsschiene 24 verfahrbar gelagert und den einzelnen Einrichtungen der Vorrichtung 10 nacheinander zustellbar. Ausgehend von der RĆ¼stposition ist in einer Verfahrrichtung der Palette 22 zunƤchst eine Erkennungseinrichtung 30 angeordnet, mittels welcher das Textil 20, insbesondere eine Markierung 21 auf dem Textil, durch eine programmierbare Steuereinrichtung 31 erkennbar ist. Die programmierbare Steuereinrichtung 31 steht mit allen Einrichtungen der Vorrichtung 10 in Verbindung. Die durch die Erkennungseinrichtung 30 ermittelten Informationen bezĆ¼glich des Textils 20 sind mittels der programmierbaren Steuereinrichtung 31 einem eindeutig definierten Druckauftrag zuordenbar. Der Druckauftrag kann mittels eines Eingabeterminals an der Vorrichtung 10 oder Ć¼ber eine Fernkommunikationsverbindung an die programmierbare Steuereinrichtung 31 durch den Benutzer Ć¼bermittelt werden. Die hierbei Ć¼bermittelten Bild- und Druckdaten werden von der programmierbaren Steuereinrichtung 31 in eine auftragsgemƤƟe Steuerung der einzelnen Einrichtungen der Vorrichtung 10 umgesetzt. Fig. 1 shows a device 10 for printing on textile surfaces. A textile 20 to be printed is provided on a pallet 22 with a printing side 25, which is located in a set-up position, in which the pallet 22 can be equipped with the textile 20. The fabric 20 is movably mounted on the pallet 22 by means of the traversing device 23 along a guide rail 24 and the individual devices of the device 10 successively deliverable. Starting from the set-up position, a detection device 30 is initially arranged in a direction of movement of the pallet 22, by means of which the textile 20, in particular a marking 21 on the textile, can be recognized by a programmable control device 31. The programmable controller 31 is in communication with all the devices of the device 10. The information determined by the recognition device 30 with respect to the textile 20 can be assigned to a clearly defined print job by means of the programmable control device 31. The print job may be transmitted to the device 10 via an input terminal or to the programmable controller 31 via a remote communication link by the user. The image and print data transmitted in this case are converted by the programmable control device 31 into an order-specific control of the individual devices of the device 10.

In Verfahrrichtung der Palette 21 ausgehend von der RĆ¼stposition der Palette 22 ist hinter der Erkennungseinrichtung 30 eine Vorbehandlungseinrichtung 40 vorgesehen, welche in einer Querrichtung zur Verfahrrichtung der Palette 22 ausgebildet ist. Die Palette 22 kann unter der Vorbehandlungseinrichtung 40 hindurchgefĆ¼hrt werden, wobei auf dem Textil 20 ein Vorbehandlungsfluid aufgebracht wird. Die Vorbehandlungseinrichtung 40 weist eine Vielzahl von DĆ¼sen 41 auf, welche entlang der Vorbehandlungseinrichtung 40 ausgebildet sind und sich an dieser Ć¼ber die gesamte Breite des Textils 20 auf der Palette 22 in der Querrichtung zur Verfahrrichtung der Palette 22 erstrecken. Durch individuelles Ansteuern, insbesondere Ɩffnen und SchlieƟen der DĆ¼sen 41 wƤhrend des Auftragens des Vorbehandlungsfluids auf das Textil, steuert die programmierbare Steuereinrichtung 31 die Vorbehandlungseinrichtung 40, um einen individuellen Vorbehandlungsbereich 26 auf dem Textil 20 aufzutragen, in welchem das auftragsgemƤƟe Druckbild vorsehbar ist. Dieser ist in Fig. 1 schematisch auf dem Textil 20 dargestellt. Hierbei kƶnnen insbesondere solche Bereiche der Druckseite des Textils von einer Vorbehandlung ausgenommen sein, welche nicht mit einem Druckbild bedruckt werden. Die Steuerung der Vorbehandlungseinrichtung 30 erfolgt gemƤƟ der Informationen, welche Ć¼ber das zu bedruckende Textil zu dem Druckauftrag mittels der Erkennungseinrichtung 30 an die programmierbare Steuereinrichtung 31 Ć¼bermittelt wurden beziehungsweise in der programmierbaren Steuereinrichtung 31 hinterlegt sind.In the direction of movement of the pallet 21, starting from the set-up position of the pallet 22, a pretreatment device 40 is provided behind the identification device 30, which is formed in a transverse direction to the travel direction of the pallet 22. The pallet 22 may be passed under the pre-treatment device 40, wherein a pretreatment fluid is applied to the textile 20. The pretreatment device 40 has a multiplicity of nozzles 41, which are formed along the pretreatment device 40 and extend there across the entire width of the textile 20 on the pallet 22 in the transverse direction to the travel direction of the pallet 22. By individually controlling, in particular opening and closing the nozzles 41 during the application of the pretreatment fluid to the textile, the programmable controller 31 controls the pretreatment device 40 to apply an individual pretreatment area 26 on the textile 20 in which the print image appropriate for the job can be provided. This one is in Fig. 1 shown schematically on the fabric 20. In this case, in particular those areas of the printing side of the textile may be excluded from a pretreatment, which are not printed with a printed image. The control of the pretreatment device 30 is carried out according to the information which has been transmitted via the textile to be printed to the print job by means of the recognition device 30 to the programmable controller 31 or are stored in the programmable controller 31.
