Description

Verfahren zum Färben und Mustern von Papier Es ist bekannt, fertig gelehnte, gegebenenfalls auch vorgefeuchtete Papierbahnen durch Tauchen in Farbstofflösungen zu färben sowie auch solche Papierbahnen mit Farbstofflösungen zu bedrucken.Method of dyeing and patterning paper It is known done leaned, possibly also pre-moistened paper webs by immersion in dye solutions to dye as well as to print such paper webs with dye solutions.

Es wurde nun gefunden, daß man sehr hochwertige, besonders für Sicherheitspapiere geeignete Erzeugnisse herstellen kann, wenn man geleimte, vorgenetzte, im Tauchverfahren oder nach sonstigen bekannten Verfahren uni- oder gemustert gefärbte Papiere vor oder nach dem Färbevorgang durch einen in beliebiger Weise und unter Anwendung beliebiger Muster auf die feuchte Fläche des Papiers ausgeübtenDruck an einzelnenStellen in der Farbstärke vertieft, ohne eventuell rlie Vorteile in der Erkennung von Rasuren, die eine erhebliche Sicherheit gegen Nachahmung der Papiere geben, in praktisch störendem Maße zu beseitigen. Mit der Ausübung eines solchen Druckes kann an allen oder einem Teil der Druckstelle das Auftragen von Farbstofflösungen beliebiger Art verbunden werden, wodurch weitere Nuancierungen erzielt werden können.It has now been found that you can get very high quality, especially for security papers Suitable products can be produced if one is glued, pre-wetted, in the dipping process or papers dyed in a single or patterned manner by other known processes or after the dyeing process by any means and using any Pressure exerted on the damp surface of the paper at individual points in the pattern the color strength deepens, without any advantages in the detection of shaves, which give a considerable security against copying of the papers, in practice to eliminate disruptive dimensions. With the exertion of such pressure it can affect everyone or part of the pressure point, the application of dye solutions of any kind be connected, whereby further nuances can be achieved.

Zur Sicherung und Verfeinerung des durch die Erfindung zu erzielenden Effektes kann vor oder hinter der Druckwalze ein Spülvorgang eingeschaltet werden, was insbesondere dann von Vorteil ist, wenn solche Färbevorgänge Anwendung finden, deren Tiefenwirkung nicht oder schwer durch Abgrenzung der Dauer der Farbstoffeinwirkung geregelt werden kann.To secure and refine what is to be achieved by the invention Effect, a rinsing process can be switched on in front of or behind the print roller, which is particularly advantageous when such dyeing processes are used, their in-depth effect is difficult or impossible due to the delimitation of the duration of the dye exposure can be regulated.

Zur Erhöhung der Sicherheit kann man in bekannter Weise zum Färben solche Farbstoffe verwenden, die unter dem Einfiuß von Chemikalien, wie beispielsweise Säuren, Alkali oder Chlor, veränderlich sind.To increase safety, dyeing can be done in a known manner use such dyes that are exposed to chemicals such as Acids, alkali or chlorine, are changeable.
