Description

Die Erfindung betrifft ein Verfahren zur Veredlung von Wertpapierdruckbogen.The invention relates to a method for finishing securities printing sheets.

Ein an Wertpapieren bekanntes Sicherheitsmerkmal ist das Wasserzeichen, welches bereits bei der Herstellung des "Wertpapier-Papiers" erzeugt wird. Wasserzeichen werden erzeugt, indem durch entsprechende Verfahren bei der Papierherstellung ein gezielt unterschiedlicher Aufbau des Papierkörpers bzgl. der Materialstärke und/oder Materialdichte erreicht wird. Durch den unterschiedlichen Aufbau, d.h. durch die erreichte unterschiedliche Lichtdurchlässigkeit des Materials, lassen sich im Papier gewünschte Motive (z.B. Porträts) herstellen. Nachteilig ist dabei, dass diese Motive erst deutlich sichtbar werden, wenn das Papier auf einen Lichttisch gelegt oder gegen Tageslicht gehalten wird. Des Weiteren nutzen sich diese Papiere bei Gebrauch stark ab, wodurch das Erkennen der Sicherheitsmerkmale teilweise nicht mehr möglich ist.A security feature known on securities is the watermark that is already generated in the production of the "security paper". Watermarks are generated by a correspondingly different structure of the paper body with respect to the material thickness and / or material density is achieved by appropriate methods in papermaking. Due to the different structure, i. by the achieved different light transmission of the material, desired motifs (for example portraits) can be produced in the paper. A disadvantage is that these motifs are only clearly visible when the paper is placed on a light table or held against daylight. Furthermore, these papers severely deteriorate in use, which makes the detection of security features sometimes impossible.

Aufgabe der Erfindung ist die Schaffung eines Verfahrens zur Veredlung von Wertpapierdruckbogen zur besseren Erkennung der Wasserzeichen.The object of the invention is to provide a method for finishing securities printing sheets for better recognition of the watermarks.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des ersten Patentanspruchs gelöst.According to the invention the object is solved by the features of the first claim.

Durch die Lackierung, insbesondere mit farblosem Lack, von Wertpapier-Papier wird, in Abhängigkeit vom Papieraufbau, der Lackart, dem Lackauftragsverfahren und der Auftragsmenge eine starke Zunahme der Transparenz des Papiers erreicht. Wird ein Wasserzeichen von Wertpapier-Papier einseitig oder beidseitig lackiert, so ist das Motiv des Wasserzeichens aufgrund der unterschiedlichen Transparenz, die wieder vom unterschiedlichen Papieraufbau herrührt, deutlicher sichtbar. Das Wasserzeichen ist auch ohne Hilfsmittel (Lichtquelle) gut erkennbar. Hilfsmittel wie z.B. Lichtquellen oder einfach dunkle Unterlagen verstärken diesen Effekt weiter.By coating, in particular with colorless lacquer, of security paper, depending on the paper structure, the type of lacquer, the lacquer application method and the amount applied, a great increase in the transparency of the paper is achieved. If a watermark of security paper is coated on one or both sides, the motif of the watermark is more clearly visible due to the different transparency that results from the different paper composition. The watermark is easily recognizable even without aids (light source). Aids such as e.g. Light sources or simply dark backgrounds further enhance this effect.

Nachfolgend wird das Verfahren an einem Ausführungsbeispiel näher erläutert.
Ein mit Wasserzeichen ausgestatteter Wertpapierbogen wird in einer Druckmaschine bedruckt.
Anschließend, d.h. nach dem Druckvorgang, wird der Wertpapierdruckbogen in der Druckmaschine mit einer speziellen Lackiereinrichtung oder in einem externen Lackwerk mit Bogenanleger und Bogenauslage lackiert.
The method will be explained in more detail on an exemplary embodiment.
A watermarked security sheet is printed on a printing press.
Subsequently, ie after the printing process, the securities printing sheet is painted in the printing press with a special coating device or in an external coating unit with sheet feeder and sheet delivery.

Zweckmäßigerweise erfolgt eine Gesamtbogenlackierung und die Lackierung bestimmter Teile des Gesamtbogens d.h. der Teil des Bogens der mit Wasserzeichen versehen ist.
Die Teillackierung verbessert die Erkennbarkeit der Wasserzeichen und die Gesamtlackierung verlängert die Erkennbarkeit der Wasserzeichen beilängerem Gebrauch der Wertpapiere und die Lebensdauer derselben.
Um den Herstellungsprozeß der Wertpapiere durch die Lackierung nicht zu verlängern ist es vorteilhaft, dass der Lackiervorgang - Gesamt- und Teillackierung - in einem Arbeitsgang erfolgt. Dazu ist einem Druckzylinder ein erstes Lackierwerk - Lackierzylinder, Rasterwalze mit Kammerrakel - zugeordnet und dem Lackierzylinder ist ein zweites Lackierwerk-Lakkierzylinder, Rasterwalze mit Kammerrakel - vorgeordnet.
Die Lackierung erfolgt mit farblosem Lack.
Conveniently, a total sheet painting and painting of certain parts of the overall sheet that is the part of the sheet is provided with watermarks.
Partial painting enhances the visibility of the watermarks and the overall finish extends the visibility of the watermarks to more casual use of the securities and the life of the same.
In order not to prolong the manufacturing process of the securities by the coating, it is advantageous that the painting process - total and partial painting - done in a single operation. For this purpose, a printing cylinder a first coating unit - painting cylinder, anilox roller with chamber doctor blade - associated with the painting and a second coating Lakkierzylinder, anilox roller with chamber doctor blade - upstream.
The painting is done with colorless paint.

Claims (4)

  1. Method of upgrading security paper print sheets, characterised in that security paper print sheets provided with watermarks are after printing partly lacquered, or the lacquering is carried out over the whole area and partly, for increase in their durability and for emphasising the watermarks by increasing their transparency.
  2. Method of upgrading according to claim 1, characterised in that the security paper sheets are coated in one working process over the whole area with a first lacquer coating and over a partial area with a second lacquer coating.
  3. Method of upgrading according to claim 1 or 2, characterised in that the security paper sheets are lacquered in those regions of the security paper sheets which are provided with watermarks.
  4. Method of upgrading according to claim 1, characterised in that lacquering is with colourless lacquer.
