Description
Verfahren und Einrichtung zum Trocknen von Drucken durch Ozon Es ist bekannt, das Trocknen von Drucken beliebiger Art dadurch zu beschleunigen, daß man auf die Drucke Ozon einwirken läßt. Dies wird z. B. so ausgeführt, daß man ozonisierte Luft auf die bedruckten Bogen, Stoffe o. dgl. aufbläst. Die Trocknungsdauer wird hierdurch ganz erheblich verkürzt, was besonders bei Mehrfarbendrucken wichtig ist. So kann man z. B. die Trocknungsdauer eines Mehrfarbendruckes durch Aufblasen von ozonisierter Luft von vier Tagen auf einenTag, also um 75 °f, herabsetzen. Es ergeben sich jedoch Schwierigkeiten, weil durch das freie Ausblasen der ozonisierten Luft die Bedienungsmannschaft der Maschinen im Arbeitsraum belästigt wird, und weil das Ozon angreifend und zerstörend auf Gummiteile der Maschinen, z. B. auf die Gummitücher bei Offsetmaschinen, einwirken kann.Method and device for drying prints by ozone It is known to accelerate the drying of prints of any kind by the fact that lets ozone act on the prints. This is z. B. designed so that one ozonated Air blows onto the printed sheets, fabrics or the like. The drying time will this considerably shortens it, which is particularly important for multi-color printing. So you can z. B. the drying time of a multi-color print by inflating Reduce ozonated air from four days to one day, i.e. by 75 ° f. It surrendered However, difficulties arise because of the free blowing out of the ozonated air the operators of the machines in the work area are harassed, and because that Ozone attacking and destroying rubber parts of the machines, e.g. B. on the blankets on offset machines.
Man hat ferner daran gedacht, die bedruckten Bogen oder Bahnen während oder nach dem Drucken durch einen Verschlag oder Raum zu führen, in dem das Ozon zur Wirkung kommt. Diese Lösung ist in den meisten Fällen nicht anwendbar, da der Platz für solche Verschläge meist nicht vorhanden ist und weil der freie Zutritt zur Maschine und die überslchtlichkelt des Papierablaufes der Maschine dadurch gehindert werden. Gemäß der Erfindung werden diese Schwierigkeiten dadurch vermieden, daß die zu bedruckenden Bogen oder Bahnen vor dem Druck mit Ozon behandelt werden. Papier und andere Stoffe haben bekanntlich die Eigenschäft, Ozon stark zu absorbieren. Wird das so vorbehandelte Papier bedruckt, so wirkt das absorbierte Ozon trocknend auf die Druckfarbe, ohne daß Ozon in den Arbeitsraum austreten kann.One has also thought of the printed sheets or webs during or after printing through a shed or room in which the ozone comes into effect. This solution is not applicable in most cases because the There is usually no space for such crates and because there is free access to the machine and the overview of the paper flow of the machine is hindered will. According to the invention, these difficulties are avoided in that the sheets or webs to be printed are treated with ozone before printing. paper and other substances are known to have the property of strongly absorbing ozone. If the paper pretreated in this way is printed, the absorbed ozone has a drying effect on the printing ink without ozone being able to escape into the work area.
Da der Bogen auf beiden Seiten mit Ozon behandelt werden kann, so kommt beim Ablegen aus der Maschine stets die ozonisierte, ungedruckte Seite des Bogens auf die bedruckte Seite des darunterliegenden, ebenfalls ozonisierten Bogens. So findet also durch das auf der Unterseite des zweiten Bogens absorbierte Ozon ein Nachtrocknen der Farbe des ersten Bogens statt, so daß ein Beschmutzen der Rückseite bedruckter Bogen durch Abdruck nicht trockener Farbe vermieden wird.Since the bow can be treated with ozone on both sides, so The ozonized, unprinted side of the always comes out of the machine when it is put down Sheet on the printed side of the underlying, also ozonated sheet. So it takes place through the ozone absorbed on the bottom of the second arc drying of the paint of the first sheet takes place, so that the reverse side is soiled printed sheet is avoided by imprinting non-dry ink.
Das Verfahren kann man so ausüben, daß man die Papierrolle, deren Bahn anschließend bedruckt werden soll, in einen Verschlag einbaut, in den ozonisierte Luft oder ozonisierter Sauerstoff geleitet wird. Beim Bedrucken von einzelnen Bogen kann man in entsprechender Weise die Anlegevorrichtung mit einem Verschlag umgeben. Statt dessen kann man auch eine besondere Abänderung der Papierführung zwischen den zu, bedruckenden Papierrollen bzw. dem Bogenstapel und der Druckmaschine vorsehen, in der das Papier ozonisiert wird.The method can be practiced in such a way that the roll of paper whose The web is then to be printed, built into a crate in which the ozonated Air or ozonated oxygen. When printing on individual sheets you can surround the application device with a crate in a corresponding manner. Instead, you can also a special change to the paper guide between the paper rolls to be printed or the stack of sheets and the printing machine provide in which the paper is ozonated.
Man kann das Verfahren auch so ausüben, daß man die zu bedruckenden Bogen oder Bahnen als Dielektrikum zwischen zwei für die Ozongewinnung geeigneten Polen hohen Spannungsgefälles durchlaufen läßt.You can also practice the process in such a way that you can print the Arches or tracks as a dielectric between two suitable for ozone production Poland can go through a high voltage gradient.
