Description
Die Erfindung betrifft ein Verfahren zur Erzeugung von lithographischen Druckformen, die eine metallische Druckfläche, vorzugsweise aus Aluminium, aufweisen. Es können hierfür reine Metallfolien, z. B. aus Aluminium, Zink, jedoch vorzugsweise sehr dünne Aluminiumfolien verwendet werden, die mit einer Papier- oder Kunststoffolie kaschiert sind.The invention relates to a method for producing lithographic printing forms that have a metallic pressure surface, preferably made of aluminum. For this purpose, pure metal foils, e.g. B. made of aluminum, zinc, but preferably very thin aluminum foils are used with are laminated with a paper or plastic film.
Das Verfahren kann sowohl für lithographische Druckformfolien verwendet werden, welche im Offsetdruck Verwendung finden sollen, als auch für solche, die von der nicht druckenden Seite her durch Hinterlegung von Fettträgern beschriftet werden, also zum direkten lithographischen Druck dienen.The method can be used both for lithographic printing form foils, which are used in offset printing Are to be used, as well as for those that are deposited from the non-printing side are labeled by grease carriers, i.e. are used for direct lithographic printing.
Die bisher für den lithographischen Druck verwendeten Druckformfolien erforderten eine Aufrauhung der Druckoberfläche, um diese hydrophil, also gut wasserführend, zu gestalten. Diese Aufrauhung erfolgt eventuell entweder auf mechanischem Wege, ζ. B. durch Bürsten oder Schleifen, oder auf chemischem Wege durch Ätzen oder durch elektrolytische Oxydation des Metalls. In jedem Fall mußte diese Behandlung vor der Beschriftung der Druckformfolie erfolgen.The printing form foils previously used for lithographic printing required roughening the printing surface in order to make it hydrophilic, i.e. well water-bearing. This roughening takes place possibly either mechanically, ζ. B. by brushing or grinding, or on chemical Paths by etching or by electrolytic oxidation of the metal. In any case, had to this treatment takes place before the printing form foil is inscribed.
Es ist auch ein Verfahren bekannt, bei welchem zur Erzeugung einer wasseranziehenden Oberfläche Wasserglas mehrmals aufgetragen wird. Das Wasserglas, in der für eine Benetzungsmöglichkeit erforderlichen Konzentration neigt jedoch dazu, die fetthaltigen Bildstellen stark anzugreifen, da das Wasserglas mit dem Fett wasserlösliche Seifen bildet. Bei der späteren Feuchtung fallen jedoch diese Bildteile allmählich aus und ergeben Schriftschwund.A method is also known in which to produce a water-attracting surface Water glass is applied several times. The water glass, in the one required for a possibility of wetting Concentration, however, tends to severely attack the fatty areas in the image, since the water glass forms water-soluble soaps with the fat. However, these parts of the image gradually fall during the subsequent dampening and result in font loss.
Es ist daher erforderlich, die Bildstellen der Druckformen erst durch Vorbehandlung in den lithographischen Zustand überzuführen bzw. mit Fettfarbe zu verstärken. Außerdem ist bei dem bekannten Verfahren zur Erzielung einer wirklich fettabstoßenden Wirkung, die erst durch eine genügende Schichtdicke der bildfreien Stellen zu erreichen ist, eine mehrmalige Behandlung mit Wasserglas erforderlich. Hinzukommt, daß durch diese notwendige Erhöhung der bildfreien Stellen die eigentlichen Bildstellen vertieft liegen und daher schwerer Farbe annehmen, als wenn sie auf gleichem Niveau bleiben würden.It is therefore necessary to first treat the image areas of the printing formes in the lithographic To transfer the state or to strengthen it with grease paint. In addition, in the known method to achieve a really grease-repellent effect, which can only be achieved through a sufficient layer thickness of the To achieve image-free areas, repeated treatment with water glass is required. Come in addition, that this necessary increase in the image-free areas deepens the actual image areas and therefore take on more color than if they remained at the same level.
Endlich ist die Wasserglasschicht einer ständig lösenden Wirkung des Feuchtwassers ausgesetzt, und
eine größere Auflage ist nur zu erzielen, wenn das Wasserglas durch Erhitzen unlöslich gemacht worden
ist. Es besteht kein Zweifel, daß dieser Erhitzungsvorgang bei der Herstellung von Platten nicht nur
äußerst umständlich, sondern auch inopportun ist, da jede Hitze Spannungen in dem Metall und große Än-Verf

There is no doubt that this heating process in the manufacture of panels is not only extremely cumbersome but also inopportune, since any heat creates stresses in the metal and great processes for generating it

Erfindungsgemäß werden zur Erzeugung von lithographischen Druckformen Druckfolien verwendet, welche mechanisch, chemisch oder elektrolytisch nicht aufgerauht sind, sondern glattgewalzte Metallfolien allein oder kaschiert mit anderen Stoffen, und die Druckformfolien werden nach der Beschriftung mit fetthaltigen bzw. fettannehmenden Stoffen mit einer Aufschwemmung von Kalziumhydroxyd (KaIkmilch) und einer Lösung eines synthetisch hergestellten oder natürlichen organischen Kolloides, z. B. Gummarabikum, behandelt. Hierbei ist es zweckmäßig, die Aufschwemmung des Kalziumhydroxydes und die Kolloidlösung in einer Flüssigkeit zu vereinen. Es können jedoch dieselben auch hintereinander angewandt werden. Die Folien werden kurz vor dem Andrucken mit einer schwach sauren wäßrigen Lösung kurz behandelt.According to the invention, printing foils are used to produce lithographic printing forms, which are not mechanically, chemically or electrolytically roughened, but rather smooth-rolled metal foils alone or laminated with other materials, and the printing form foils are after the inscription with fatty or fat-absorbing substances with a suspension of calcium hydroxide (chalk milk) and a solution of a synthetically produced or natural organic colloid, e.g. B. Gum arabic treated. It is useful here to suspend the calcium hydroxide and to combine the colloid solution in a liquid. However, the same can also be used one after the other can be applied. Shortly before printing, the foils are treated with a weakly acidic aqueous solution Solution briefly treated.
Es wurde gefunden, daß die Oberfläche der glattgewalzten Druckformfolie eine gute Fettannahme zur Beschriftung zeigt und infolge der unzerstörten Glätte der Oberfläche eine besonders gute Schärfe im Schriftbild ergibt. Die Behandlung der glattgewalzten Oberfläche der Druckformfolie mit Kalziumhydroxyd und einer Kolloidlösung nach der Beschriftung zeigte eine besonders überraschende Eignung für diesen Zweck, da einmal eine völlig gleichmäßige BenetzungIt was found that the surface of the rolled flat Printing form film shows good fat absorption for lettering and as a result of the undamaged smoothness the surface gives a particularly good sharpness in the typeface. Treatment of the rolled flat Surface of the printing plate with calcium hydroxide and a colloid solution after the inscription showed a particularly surprising suitability for this purpose, because once a completely uniform wetting

der an sich sonst nicht hydrophilen, glattgewalzten Metalloberfläche erfolgt und gleichzeitig die Schriftbzw. Bildstellen der Druckformfolien von dem Kalziumhydroxyd praktisch nicht angegriffen "werden/ Durch die Behandlung mit dem Kalziumhydroxyd wird die Oberfläche gleichsam befähigt, das gleichzeitig oder anschließend aufgebrachte synthetisch hergestellte oder natürliche organische Kolloid, vorzugsweise Gummiarabikum, zu verankern, so daß die vor der Behandlung fettfreundliche und wasserabstoßende Oberfläche in eine fettabstoßende hydrophile Oberfläche verwandelt wird. Da sich beim Trocknen der Druckformfolien, durch die Kohlensäure der Luft verursacht, teilweise Kalziumkarbonat bildet, ist es erforderlich, die Druckformfolie vor dem Andrucken mit einer schwach sauren wäßrigen Lösung kurz zu behandeln.the otherwise not hydrophilic, rolled smooth metal surface and at the same time the writing or. Image areas of the printing forme foils are practically not attacked by the calcium hydroxide "/ The treatment with calcium hydroxide enables the surface, as it were, at the same time or subsequently applied synthetically produced or natural organic colloid, preferably Gum arabic to anchor, so that the prior to treatment is fat-friendly and water-repellent Surface is transformed into a grease-repellent hydrophilic surface. As the It is printing form foils that cause carbonic acid in the air to partially form calcium carbonate It is necessary to briefly close the printing form film with a weakly acidic aqueous solution before printing treat.
Beispielsweise kann als Behandlungsmittel für die glattgewalzte Druckformfolie folgende Rezeptur angewandt werden:For example, the following formulation can be used as a treatment agent for the rolled flat printing form film will:
20 g Gummiarabikum,
80 g Wasser,20 g gum arabic,
80 g water,
50 g 10%ige Kalziumhydroxydaufschwemmung in Wasser.50 g 10% calcium hydroxide suspension in water.
5 g Kalziumhydroxyd,5 g calcium hydroxide,
125 g Wasser, 20 g Gummiarabikum.125 g water, 20 g gum arabic.
Der Anteil an Kalziumhydroxyd im erstgenannten Beispiel muß nicht 5 g betragen, er kann etwa zwischen 2 und 15 g schwanken, und der Anteil des Gummiarabikums kann zwischen 10 und 30 g schwanken.The proportion of calcium hydroxide in the first example does not have to be 5 g, it can be between 2 and 15 g and the amount of gum arabic can vary between 10 and 30 g vary.
Für die Behandlung vor dem Drucken kann beispielsweise eine 0,5%>ige wäßrige Phosphorsäurelösung verwendet werden.A 0.5% aqueous phosphoric acid solution, for example, can be used for the treatment before printing be used.
