Die farbgebende oder lumineszierende Schicht wird durch vollflächiges oder partielles Drucken aufgebracht.
Durch Überdrucken lassen sich auch bei geringster Maschinentoleranz immer nur die Aussparungen überlappende Bereiche mit der entsprechenden farbgebenden oder lumineszierenden Druckfarbe versehen.
Femer ist zur Erzielung des farblichen Kontrasts die zusätzliche Schicht nötig, was bei den immer strengeren Anforderungen an die Präzision und geringe Dicke der Sicherheitsmerkmale für Wertdokumente einen Nachteil darstellt.
Ferner können auch monoaxial gereckte flexible Kunststofffolien verwendet werden.
Unter metallischen Beschichtungen werden sowohl Metall-Beschichtungen als auch Beschichtungen mit Metallverbindungen verstanden.
Unter Metalleffektfarben werden hier auch auf Basis von Glimmer, belegt mit TiO2 oder Fe, hergestellte Farben oder Lacke verstanden.

Anschließend wird auf das mit der partiellen opaken Beschichtung versehene Trägersubstrat eine in einem Lösungsmittel lösliche und mit Farbstoffen angereicherte Druckfarbe aufgebracht.
Gegebenfalls kann die Druckfarbe auch pigmentiert sein.
Es kann aber auch ein reiner Farbauftrag erfolgen.
Als Farbstoffe kommen alle in einem Lösungsmittel löslichen Farbstoffe, beispielsweise Azofarbstoffe, Phthalocyaninblau, i-Indolidingelb, Dioxazinviolett, Triphenylmethanfarbstoffe, Metallkomplex-Farbstoffe, anionische oder kationische Färbstoffe und Sublimationsfarbstoffe, Textilfarbstoffe, Lumineszenzfarbstoffe, natürliche oder naturidente Farbstoffe, Papierfarbstoffe und dergleichen in Frage.
Die Aufbringung dieser Schicht(en) kann durch ein beliebiges Verfahren, beispielsweise durch Tiefdruck, Flexodruck, Siebdruck, Offset-, Digitaldruck (Inkjet-, Trocken- und Flüssigtoner) und dergleichen erfolgen.
Dabei sind lösungsmittelhaltige Farben- und/oder Lacksysteme, wässrige und auch lösungsmittelfreie Lacksysteme verwendbar.
Als Bindemittel kommen verschiedene natürliche oder synthetische Bindemittel in Frage.
Weiters können auch dotierte oder nicht dotierte Halbleiter wie beispielsweise Silicium, Germanium oder lonenleiter wie amorphe oder kristalline Metalloxide oder Metallsulfide als Zusatz verwendet werden. Ferner können zur Einstellung der elektrischen Eigenschaften der Schicht polare oder teilweise polare Verbindungen, wie Tenside oder unpolare Verbindungen wie Silikonadditive oder hygroskopische oder nicht hygroskopische Salze verwendet oder zugesetzt werden.
Beispielsweise kann Polyethylendioxythiophen mit Polystyrolsulfonat als Matrixpolymer verwendet werden.
Es werden aber bevorzugt die Monomere bzw. Vorpolymere zur Bildung der elektrisch leitfähigen Polymere aufgebracht und in situ polymerisiert.
Dadurch ist es möglich, das für viele Anwendungen erwünschte bzw. erforderliche metallisch glänzende Erscheinungsbild in einem Arbeitsgang bereits durch Verdrucken dieser Magnetfarben zu erzeugen. Ein Überdrucken bzw. Beschichten mit metallischen oder Metall-Schichten zur Erzeugung des gewünschten Erscheinungsbildes ist daher nicht nötig, kann aber beispielsweise zur Einbringung weiterer Identifikationsmerkmale problemlos erfolgen.
Speziell zum Anfärben von Magnetpigmenten lassen sich alle bekannten löslichen und nicht löslichen Farbstoffe bzw. Pigmente verwenden. So kann beispielsweise eine braune Magnetfarbe durch Zugabe von Metallen in ihrem Farbton metallisch, beispielsweise silbrig eingestellt werden.
Darin bedeuten 1 das Trägersubstrat, 2 die opake Beschichtung 3 die Aussparungen, 4 ein gegebenenfalls vorhandenes weiteres funktionelles Merkmal.
Ein entsprechender Sicherheitsfaden oder -streifen kann auch als Randverstärkung von Verpackungen, Wertdokumenten und dergleichen im Bereich der Kanten aber auch als beispielsweise Längs- oder Quer - Verstärkung in der Verpackung oder im Wertdokument verwendet werden, wobei auch jeweils mehrer Fäden oder Streifen in definiertem Abstand zueinander vorgesehen sein können.
