Abstract

The marking, printing or structuring method involves applying a lacquer and/or a coloured ink to the surface of the card. The latter is selectively illuminated in accordance with the required markings, print characters, or structures before complete hardening, using UV light. The illuminated areas exhibit local variations in smoothness or colour. The UV light may be provided by a polychromatic beam, with different filters inserted in the beam path for filtering out corresponding wavelengths.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Aufbringen von Markierungen, Beschriftungen und Strukturierungen auf die Oberfläche einer Ausweiskarte oder einer anderen Karte.The invention relates to a method for applying markings, Inscriptions and structuring on the surface of an ID card or one other card.

Die Farben auf Ausweiskarten, wie z.B. Chipkarten (Telefonkarten,Magnetstreifenkarten usw.) werden durch Sieb- oder Offsettdruck aufgetragen. Sie werden durch Wärme, Ifrarotstrahlung oder UV-licht vollflächig ausgehärtet bzw. getrocknet.The colors on ID cards, such as Chip cards (phone cards, magnetic stripe cards etc.) are applied by screen or offset printing. You will be warm Infrared radiation or UV light fully hardened or dried.

Will man Schrift, Schattierungen, Strukturen, Marmorierungen, Symbole erzeugen, so ist es nötig, verschiedene Farben zu verwenden und sie gleichzeitig oder nacheinander mit den oben genannten Verfahren auszuhärten.If you want to create writing, shades, structures, marbling, symbols, so it is necessary to use different colors and use them simultaneously or one after the other cure with the above methods.

Beim vollflächigen Aushärten von Farben mit ultravioletter Strahlung hängt der Glanzgrad der Farben von der Wellenlänge, der Intensität und der Belichtungszeit ab. Beschriftungen werden auch durch Einbrennen mit Laserstrahl hergestellt.It depends on the full-surface curing of colors with ultraviolet radiation The degree of gloss of the colors depends on the wavelength, the intensity and the exposure time. Inscriptions are also produced by burning in with a laser beam.

Es ist bisher nicht möglich gewesen Schrift, Schattierungen, Strukturen, Marmorierungen, Symbole, also definiert sich abgrenzende Bereiche, herzustellen, die sich durch den Glanzgrad gegeneinander abgrenzen, ohne daß man nicht zumindest verschiedene Farbnuancen oder sogar verschiedene Farben verwendete.So far it has not been possible to use fonts, shades, structures, Marbling, symbols, that is, defining bounding areas to produce that distinguish themselves from each other by the degree of gloss, without not at least different color shades or even different colors used.

Aufgabe der Erfindung ist es daher, ein Verfahren zu schaffen, mit dem man auf einer Karte, sich durch unterschiedliche Glanzgrade einer Farbe abgrenzende, Bereiche erzeugen kann.The object of the invention is therefore to provide a method with which one Map, areas delimited by different degrees of gloss of a color can generate.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Die sich daran anschließenden Unteransprüche enthalten vorteilhafte und förderliche Ausgestaltungen der Erfindung.This object is achieved by the characterizing features of patent claim 1 solved. The subsequent sub-claims contain advantageous and beneficial embodiments of the invention.

An Hand der beigefügten Zeichnungen soll die Erfindung nachfolgend näher erläutert werden.The invention will be explained in more detail below with reference to the accompanying drawings will.

Bei dem erfindungsmäßigen Verfahren wird zuerst Lack bzw. Druckfarbe auf die Karte aufgetragen. Dann wegen ausgewählte Bereiche des noch nicht trockenen Lackes mit UV-Licht belichtet, wodurch dieser an den belichteten Stellen aushärtet. Die belichteten Bereiche setzen sich dann von ihrer Umgebung durch einen anderen Glanzgrad ab. Der Glanzgrad selber wird wahlweise durch die Wellenlänge und/oder der Intesität des Strahles und/oder der Belichtungszeit bestimmt; er kann also somit variiert werden. Die anderen Flächen härten durch Wärme, Infrarotstrahlung, oder durch UV-Licht anderer Wellenlänge und/oder anderer Intensität und/oder einer anderen Belichtungszeit aus.In the method according to the invention, lacquer or printing ink is first applied to the card. Then exposed to selected areas of the not yet dry varnish with UV light, causing it to harden in the exposed areas. The exposed areas are then separated from their surroundings by a different degree of gloss. The degree of gloss itself is optionally determined by the wavelength and / or the intensity of the beam and / or the exposure time; it can therefore be varied. The other surfaces harden by heat, infrared radiation, or by UV light of a different wavelength and / or a different intensity and / or a different exposure time.

Um zu erreichen , daß bestimmte, ausgewählte Bereiche mit einer Wellenlänge und einer bestimmten Belichtungszeit des UV-Lichts belichtet werden, und dadurch einen bestimmten Glanzgrad annehmen, gibt es verschiedene Möglichkeiten.To achieve certain selected areas with a wavelength and a certain exposure time of UV light, and thereby one assume a certain degree of gloss, there are different options.

Eine Möglichkeit ist es, die Karte durch eine Maske, bei der ausgewählte Bereiche ausgespart sind, mit UV-Licht. Licht eine bestimmte Zeit zu belichten (Fig.1,Fig.2).One way is to map the map through a selected area are left out with UV light. Light to expose a certain time (Fig.1, Fig.2).

Eine andere Möglichkeit ist es, die ausgewählten Bereiche mit einem Strahl aus UV-Licht zu belichten, der einen programmierten Weg abläuft (Fig.3). Hierbei gibt es zwei Verfahren: das Rasterverfahren und das Vektorverfahren.Another option is to cover the selected areas with a beam of UV light to expose that follows a programmed path (Fig. 3). There are two Process: the raster process and the vector process.

Beim Rasterverfahren wird eine Struktur aus verschiedenen Glanzgraden dadurch geschaffen, daß man den UV-Strahl wie bei einem Oszilloskop zeilenweise über die Oberfläche der Karte wandern läßt, wobei die erzeugten Glanzgrade von der Wellenlänge und der Auslenkungsgeschwindigkeit des Strahles abhängen.In the screening process, a structure with different degrees of gloss is created created that the UV beam line by line like an oscilloscope over the Surface of the map can move, the degrees of gloss produced by the Depend on the wavelength and the deflection speed of the beam.

Beim Vektorverfahren werden nur die Punkte bestrahlt, die die vorgesehene Kontur beschreiben. Die übrigen Bereiche härten durch Wärme, Infrarotstrahlung oder durch UV-Licht größerer Wellenlänge aus.With the vector method, only those points are irradiated that have the intended contour describe. The remaining areas harden through heat, infrared radiation or through UV light of longer wavelength.

Das verwendete UV-Licht kann sowohl monochromatisch (nur eine Wellenlänge) als auch polychromatisch (entweder als kontinuierliches Spektrum oder als Bündel einzelner Wellenlängen) sein.The UV light used can be both monochromatic (only one wavelength) also polychromatic (either as a continuous spectrum or as a bundle of individual ones Wavelengths).

Bei Verwendung von polychromatischen Licht, kann man den Glanzgrad auch dadurch verändern, daß man dem Strahler Filter nachschaltet, die bestimmte Wellenlängen herausfiltern.When using polychromatic light, the degree of gloss can also be changed change that one follows the radiator filter, the certain wavelengths filter out.

Die stärkste Veränderung des Glanzgrades wird durch die Verwendung von vakuum-ultravioletten Licht erzielt.The strongest change in gloss level is due to the use of vacuum ultraviolet Light achieved.

Dieses vakuum-ultraviolette Licht kann z.B. im Excimer-Verfahren erstellt werden.Einige Beispiele für die, mit dem erfindungsgemäßen Verfahren hergestellten Karten zeigen Fig. 4-6 (Symbole, Marmorierung, Weltkarte). This vacuum ultraviolet light can be generated, for example, in the excimer process. Some examples of the maps produced using the method according to the invention are shown in FIGS. 4-6 (symbols, marbling, world map).

Die selektive Verwendung von vakuum-ultraviolettem Licht zur Erzielung verschiedener Glanzgrade auf einer Kartenoberfläche ist somit besonders vorteilhaft.The selective use of vacuum ultraviolet light to achieve various Degrees of gloss on a card surface are therefore particularly advantageous.
