Abstract
Description
Die Erfindung betrifft eine Tampondruckvorrichtung zur Übertragung definierter Mengen Druckmedium pro Flächeneinheit sowie deren Verwendung.The invention relates to a pad printing device for transferring defined amounts of printing medium per unit area and the use thereof.
Tampondruckverfahren sind seit 1968 bekannt und eignen sich auch zum Bedrucken unebener Oberflächen, denen sich flexible, das Druckmedium übertragende Tampons anpassen. Ein Tampondrucker ist bspw. in der DE-OS 19 39 437 beschrieben. Das zu druckende Bildelement ist in einem Klischee, der Druckform, vertieft eingeätzt. Das Druckmedium wird in dieses Klischee überführt, nach einem Rakelvorgang, der das im Klischee aufgenommene Druckmedium dosiert, wird von dem Tampon das im Klischee verbliebene Druckmedium vollständig aufgenommen und auf den zu bedruckenden Gegenstand übertragen. Eine Übersicht über Anwendungen und Eigenschaften des Tampondruckverfahrens findet sich im Prospekt der Fa. TAMPOPRINT GMbH, Daimlerstraße 27/1 in Korntal-Münchingen, auf den zur Vermeidung von Wiederholungen in vollem Umfang bezug genommen wird.Pad printing processes have been known since 1968 and are also suitable for printing on uneven surfaces to which flexible tampons that transfer the printing medium adapt. A pad printer is described, for example, in DE-OS 19 39 437. The picture element to be printed is deeply etched in a cliché, the printing form. The printing medium is transferred into this cliché, after a squeegee process which doses the printing medium which has been taken up in the cliché, the printing medium remaining in the cliché is completely absorbed by the tampon and transferred to the object to be printed. An overview of the applications and properties of the pad printing process can be found in the brochure of the company TAMPOPRINT GMbH, Daimlerstrasse 27/1 in Korntal-Münchingen, to which reference is made in full to avoid repetitions.
Tampondrucker sind wegen ihrem geringen Platzbedarf sehr vorteilhaft, da sie sich problemlos in Fabrikationsstraßen integrieren und auch kapseln lassen, was bei der Verarbeitung hochwirksamer oder giftiger Druckmedien, wie Arzneistoffen Ätztinten, Polymerisationsstartern od. dgl. zum Schutz des Bedienungspersonals aber auch zur Verminderung der Verdampfungsgeschwindigkeit von flüchtigen Substanzen hilfreich ist.Pad printers are very advantageous due to their small space requirement, since they can be easily integrated into production lines and also encapsulated, which is important for the protection of operating personnel but also for reducing the evaporation rate when processing highly effective or toxic printing media, such as medicinal etching inks, polymerization starters or the like volatile substances is helpful.
Bisher ist noch nicht versucht worden, Tampondrucker für die Abgabe präzise gesteuerter Mengen Druckmedium einzusetzen; überraschenderweise hat es sich gezeigt, daß das bereits bekannte Tampondruckverfahren eine genaue Dosierung von Flächengewichten bis zu 26 g/qm in einem Druckvorgang mit einer Varianz von ± 2 % und darunter ermöglicht.So far no attempt has been made to use pad printers for the delivery of precisely controlled quantities of printing medium; Surprisingly, it has been shown that the already known tampon printing process enables precise metering of grammages up to 26 g / m 2 in one printing process with a variance of ± 2% and below.
Dabei ist es möglich, wie in der DE-A-37 27 237 "Verfahren zur Herstellung einer Darreichungs- und/oder Dosierungsform für Arzneimittelwirkstoffe mittels eines Druckverfahrens" mit gleichem Anmeldetag der Anmelderin angegeben, selbst hochempfindliche Arzneimittel oder Steuermembranen für Wirkstoffabgaben mit konstantem Flächengewicht auf entsprechende Substrate aufzubringen.It is possible, as stated in DE-A-37 27 237 "Process for the preparation of a dosage form and / or dosage form for pharmaceutical active substances by means of a printing process" with the same filing date of the applicant, even highly sensitive medicinal products or control membranes for active substance deliveries with a constant weight per unit area apply appropriate substrates.
Bei Anwendung der bisher bekannten Mittel, nämlich Variation des Tamponmaterials (bei weicheren Tampons wird mehr Druckmedium übertragen) sowie Viskosität des Druckmediums, konnte nur eine geringfügig erhöhte, immer noch konstante Menge Druckmedium an ein Substrat abgegeben werden; diese Menge reichte aber nicht für eine Beschichtung mit höheren Flächengewichten, wie über 100 g/qm aus, so daß das Tampondruckverfahren trotz hervorragender Eigenschaften für Anwendungen wie die Herstellung dickerer Schichten von Materialien in einem vorherbestimmten Muster ungeeignet war - bisher bestand auch keinerlei Interesse an der Auftragung von Schichten mit diesem Verfahren.When using the previously known means, namely variation of the tampon material (more pressure medium is transferred in the case of softer tampons) and viscosity of the pressure medium, only a slightly increased, still constant amount of pressure medium could be delivered to a substrate; however, this amount was not sufficient for a coating with higher basis weights, such as over 100 g / m2, so that the pad printing process was unsuitable for applications such as the production of thicker layers of materials in a predetermined pattern, despite excellent properties - so far there has been no interest in the Apply layers using this procedure.
Es wurden aufwendige Siebdruckverfharen eingesetzt oder komplizierte Mehrschrittauftrgungsverfahren verwendet.Elaborate screen printing processes were used or complicated multi-step application processes were used.
Aus der CH-A-259 879 ist bekannt geworden, Drucktücher zur Verwendung beim Zeugdruck zur besseren Verteilung der Farbe mit einem System kleiner paralleler Kanäle in Längsrichtung zu versehen und dadurch die Farbverteilung zu verbessern. Dabei wird dort angegeben, daß die Rillen so groß sein müssen, daß sie die Farbe gut aufnehmen und leicht verteilen. Die dort vorgeschlagene Oberflächenvergrößerung eines Drucktuches dient hierbei jedoch nicht zur Übertragung größerer Mengen Farbe, sondern zur Sicherstellung einer regelmäßigen Verteilung der Farbe auf dem Drucktuch und einer zufriedenstellenden Druckqualität über das gesamte Bild.From CH-A-259 879 it is known printing blankets for use in stuff printing for better distribution of the color with a system of small parallel channels in the longitudinal direction and thereby improve the color distribution. It is stated there that the grooves must be large enough to absorb the color well and distribute them easily. However, the surface enlargement of a printing blanket proposed there does not serve to transfer larger amounts of color, but rather to ensure a regular distribution of the color on the printing blanket and a satisfactory print quality over the entire image.
Es ist demzufolge Aufgabe der Erfindung, die bekannte Vorrichtung dahingehend weiterzuentwickeln, daß auch größere Mengen Druckmedium, als mit herkömmlichen Tampons möglich, auf ein Substrat übertragen werden.It is therefore an object of the invention to further develop the known device in such a way that even larger amounts of printing medium than possible with conventional tampons are transferred to a substrate.
Die Aufgabe wurde erfindungsgemäß durch eine gattungsgemäße Vorrichtung gelöst, indem mindestens die Druckkontaktfläche der Gesamtoberfläche des Tampons unter Beibehaltung im wesentlichen der gleichen Außenform und Formvolumens vergrößert ist.The object was achieved according to the invention by a generic device in that at least the pressure contact area of the total surface of the tampon is increased while maintaining essentially the same outer shape and shape volume.
Die Oberflächenvergrößerung kann dabei bspw. in Rasterung, Aufrauhung, Rillung oder Noppung der Tamponoberfläche bestehen und durch Bearbeitung eines fertigen Tamponkörpers oder durch Herstellung der vergrößerten Tamponoberfläche bei der Ausformung des Tamponkörpers in einer geeigneten Form hergestellt sein.The surface enlargement can consist, for example, of rastering, roughening, creasing or nubbing of the tampon surface and can be produced in a suitable shape by machining a finished tampon body or by producing the enlarged tampon surface when the tampon body is formed.
Derartige Tampons sind gegenüber den herkömmlichen mit glatter Oberfläche zur übertragung von über dem Dreifachen der bisher mit der gleichen Form übertragbaren Menge Druckmedium geeignet.Compared to the conventional tampons with a smooth surface, such tampons are suitable for transferring more than three times the amount of print medium that has previously been transferable with the same shape.
Durch die erfindungsgemäße Fortentwicklung der bekannten Tampondrucker ist es erstmals möglich, diese Maschinen bzw. das Verfahren in völlig neuen Anwendungsgebieten in vorteilhafter Weise zur Herstellung von Beschichtungen einzusetzen. So ist es bspw. bei der Herstellung von Schildern mit einem dickeren Farbauftrag, integrierten Schaltungen, wobei Photolacke oder auch Leitermaterial gedruckt werden können; zur gezielten Auftragung von Polymerisationsstartern auf Präpolymere, zur Auftragung von Ätzflüssigkeiten zur Herstellung von Ätzmustern, zur Übertragung von Porzellanfarben, die Herstellung von pharmazeutischen Darreichungs- und/oder Dosierungsformen, wie Tabletten, dermal applizierbaren Systemen, wobei hierunter auch Systeme verstanden werden sollen, die durch Schleimhäute Stoffe abgeben, also rektale und vaginale Anwendungsformen, einsetzbar.The further development of the known pad printers according to the invention makes it possible for the first time to use these machines or the method advantageously in completely new fields of application for the production of coatings. It is, for example, in the production of signs with a thicker application of paint, integrated circuits, where photoresists or conductor material can be printed; for the targeted application of polymerization initiators to prepolymers, for the application of etching liquids for the production of etching patterns, for the transfer of porcelain colors, the production of pharmaceutical dosage forms and / or dosage forms, such as tablets, dermally applicable systems, whereby systems which are to be understood as Gives off mucous membranes, i.e. rectal and vaginal forms of use, applicable.
Eine besonders bevorzugte Anwendung findet sich bei der Herstellung pflasterartiger transdermaler therapeutischer Systeme.A particularly preferred application is found in the production of patch-like transdermal therapeutic systems.
Durch die Erfindung kann die Menge des in einem Druckvorgang abgegebenen Druckmediums in unerwarteter Weise erhöht und trotzdem eine überraschende, in engen Grenzen gleichbleibende Dosierung erhalten werden.The invention unexpectedly increases the amount of printing medium dispensed in a printing process and still achieves a surprising dosage that remains the same within narrow limits.
Durch die erfindungsgemäße Vorrichtung können nun erstmals auch wirkstoffhaltige Druckmedien, kleine Wirkstoffdosen ohne Wirkstoffverlust, wie er bei den bisher verwendeten Flächenbeschichtungsverfahren bspw. für transdermale therapeutische Systeme der Fall war, in einer erwünschten Form hergestellt werden, wodurch teurer Wirkstoff gespart und die problematische Wirkstoffabfallbeseitigung umgangen werden kann.The device according to the invention can now be used for the first time to produce active substance-containing printing media, small doses of active substance without loss of active substance, as was the case in the surface coating processes used hitherto, for example for transdermal therapeutic systems, thereby saving expensive active substance and avoiding the problematic removal of active substance waste can.
Es ist nun ferner möglich, in einem Herstellungsschritt durch Verwendung geeigneter Klischees mehrere Druckmedien wie bspw. mehrere Farben, Farben und Klebstoff, Klebstoff und einen aseptischen oder wirkstoffhaltigen Bereich bei Pflastern oder therapeutischen Systemen gleichzeitig und räumlich klar getrennt voneinander aufzutragen und dadurch einen Herstellungsschritt einzusparen. Das Klischee wie auch der Tampon selbst können temperiert werden, falls temperaturempfindliche oder auch nur in erwärmten Zustand verarbeitbare Materialien, wie bestimmte Klebstoffe, verarbeitet werden sollen. In gleicher Weise ist es möglich, diese sowie die gesamte Vorrichtung zu kühlen, wenn temperaturempfindliche Materialien be- bzw. verarbeitet werden.It is now also possible to apply several printing media such as several colors, inks and glue, glue and an aseptic or active substance-containing area in plasters or therapeutic systems at the same time and spatially separated from each other in one manufacturing step by using suitable clichés, thereby saving one manufacturing step. The cliché as well as the tampon itself can be tempered if temperature-sensitive materials or materials that can only be processed when heated, such as certain adhesives, are to be processed. In the same way, it is possible to cool this as well as the entire device if temperature-sensitive materials are processed.
Durch die Wahl eines geeigneten Tamponmaterials kann den verschiedenen Anforderungen Rechnung getragen werden, so eignen sich alle dem Fachmann geläufigen gummielastischen Materialien, wie natürliche und synthetischer Kautschuk und insbesondere Silikongummi, die entsprechend den geforderten Eigenschaften, wie Bearbeitbarkeit, Lösemittelfestigkeit, thermische Widerstandsfähigkeit oder ausreichende Elastizität bei niedrigen Temperaturen ausgewählt werden können.By choosing a suitable tampon material, the various requirements can be taken into account, so all rubber-elastic materials familiar to the person skilled in the art, such as natural and synthetic rubber and in particular silicone rubber, are suitable, which have the required properties, such as machinability, solvent resistance, thermal resistance or sufficient elasticity low temperatures can be selected.
Die Tamponform kann entsprechend dem zu verarbeitenden Substrat ausgewählt werden; es können alle üblichen Formen, sowohl stumpfkegelförmige als auch flache oder eiförmige Tampons mit vergrößerter Druckoberfläche eingesetzt werden.The tampon shape can be selected according to the substrate to be processed; all common shapes, both frustoconical and flat or egg-shaped tampons with an enlarged printing surface, can be used.
Mit einem Druckvorgang kann durch die erfindungsgemäße Vorrichtung ein Flächengewicht von etwa 200 g pro Quadratmeter Druckmedium und mehr übertragen werden, eine weitere Verbesserung der Übertragungsmenge läßt sich durch dem Fachmann geläufige Verbesserungen der Verfahrens, wie Verwendung von weicheren Tampons, anderen Druckmedien u.dgl. erreichen.With a printing process, a basis weight of about 200 g per square meter of printing medium and more can be transferred by the device according to the invention, a further improvement in the transfer quantity can be achieved by improvements in the process familiar to the person skilled in the art, such as the use of softer tampons, other printing media and the like. to reach.
