Description
Verfahren zum Auffrischen der Amalgamstellen von Druckformen mittels Quecksilbersalzlösungen Um während des Druckprozesses mit chemischen Druckformen die farbabstoßenden Amalgamstellen aufzufrischen, hat man bereits vorgeschlagen, der Farbe bzw. dem Amalgam der farbabstoßenden Stellen der Druckplatte Quecksilber in metallischer Form zuzuleiten. Um ein einwandfreies Mitteilen des Quecksilbers an den Amalgamstellen der Platte zu erzielen und weiterhin ein überschüssiges Auftragen von Quecksilber mit Rücksicht auf Gesundheitsschäden zu vermeiden, muß das Quecksilber in sehr fein verteilter Form und sehr geringen Mengen der Farbe bzw. der Platte zugeführt werden.Process for refreshing the amalgam areas of printing forms by means of Mercury salt solutions To be used during the printing process with chemical printing forms It has already been suggested to freshen up the color-repellent amalgam areas, the color or the amalgam of the ink-repellent areas of the printing plate mercury in metallic form. A correct communication of the mercury to achieve at the amalgam sites of the plate and continue to apply excess of mercury with consideration for health hazards, the mercury must be avoided in very finely divided form and very small amounts of the paint or the plate are fed.
Die Erfindung schlägt in dieser Hinsicht ein neues Verfahren vor, welches eine sehr fein verteilte Zuführung, und zwar gerade an den Amalgamstellen, gewährleistet. Es soll das Quecksilber nicht mehr in metallischer Form den Stellen zugeführt werden, sondern vielmehr in Salzform, welches in Wasser gelöst ist. Dieses mit OOuecksilbersalzen leicht angereicherte Wasser wird vermittels eines Feuchtwerks in dünnem Hauch auf die Platten übertragen und das Wasser sofort, nachdem sich die in ihm befindlichen Salze an den Amalgamstellen niedergeschlagen haben, vermittels einer zwischen Feucht- und Farbwerk angeordneten Wisch- oder Heizvorrichtung entfernt. Auf der Zeichnung ist eine schematische Darstellung des Verfahrens veranschaulicht.In this regard, the invention proposes a new method, which is a very finely distributed feed, specifically at the amalgam sites, guaranteed. The mercury should no longer be in metallic form in the bodies are supplied, but rather in salt form, which is dissolved in water. This Water slightly enriched with mercury salts is made using a dampening system Transferred in a thin whiff to the plates and the water immediately after the have deposited salts in it at the amalgam sites, mediating a wiping or heating device arranged between the dampening and inking units. A schematic representation of the method is illustrated in the drawing.
Der Druckzylinder d, auf den die chemischen Druckplatten a1 aufgespannt sind, möge sich im Uhrzeigersinn drehen: b ist die zwischen dem Formzylinder a und dem Gegendruckzylinder c laufende Papierbahn. d stellt das bekannte Farbwerk dar, während e das Feuchtwerk zeigt, vermittels dessen in Wasser gelöste Ouecksilbersalze auf die an ihm vorbeilaufenden Platten a, aufgetragen werden. Zwischen diesem Feuchtwerke und dem Farbwerk d ist nun eine Wischvorrichtung oder, wie auf der Zeichnung veranschaulicht, eine Heiztrommel f vorgesehen, welche das überschüssige Wasser sofort von den Platten wieder abnimmt, so daß die an ihren amalgamierten Stellen ständig aufgefrischten Platten a, trocken ihre Farbe vom Farbwerk wieder annehmen.The printing cylinder d on which the chemical printing plates a1 are clamped rotate clockwise: b is the one between the forme cylinder a and the impression cylinder c running paper web. d represents the well-known inking system, while e shows the dampening system, by means of its mercury salts dissolved in water be applied to the plates a passing by. Between this dampening system and the inking unit d is now a wiping device or, as illustrated in the drawing, a heating drum f is provided which removes the excess water immediately from the plates decreases again, so that the amalgamated places constantly refreshed Plates a, dry take on their color again from the inking unit.
