Abstract
Description
Die Erfindung betrifft einen Gegenstand mit einem aufgedruckten Bild aus wenigstens einer unter UV-Strahlung fluoreszierenden Druckfarbe.The invention relates to an article with an imprinted image of at least one UV-fluorescent ink.
Die Fälschungssicherheit von Verpackungen ist vor allem für die Pharmaindustrie von grosser Bedeutung. Grundsätzlich besteht jedoch auch in anderen Bereichen der Wunsch nach fälschungssicheren Verpackungen oder Produkten, insbesondere in der Kansumgüterindustrie, beispielsweise bei der Verpackung von Lebensmitteln, kosmetischen Artikeln, Kleidern, Software- und Musik CD's oder Wertpapieren. Ein Gegenstand mit einem fälschungssicheren Oberflächenbereich kann eine Verpackung, ein Packstoff, ein Packhilfsmittel oder ein Produkt selbst sein, auf dem ein Oberflächenbereich in Form eines Sicherheitsteils, beispielsweise als Etikette, mit einem optischen Effekt ausgestattet ist.The forgery-proof packaging is of great importance especially for the pharmaceutical industry. Basically, however, there is also a desire in other areas for forgery-proof packaging or products, in particular in the Kansumgüterindustrie, for example in the packaging of food, cosmetic articles, clothing, software and music CD's or securities. An article with a tamper-proof surface area can be a packaging, a packaging material, a packaging aid or a product itself, on which a surface area in the form of a security part, for example as a label, is provided with an optical effect.
Eine fälschungssichere Verpackung oder ein Packhilfsmittel kann als Originalitätsgarantie dienen, die es dem Kunden ermöglicht zu erkennen, dass das von ihm erworbene Produkt tatsächlich vom gewünschten Produzenten hergestellt und verpackt worden ist. Ein fälschungssicheres Packhilfsmittel kann u.a. auch als Erstöffnungsgarantie eingesetzt werden, beispielsweise in Form einer Etikette, einer Banderole oder eines Siegelstreifens usw., die z.B. über einem Flaschenverschluss oder über dem Verschluss eines Weithalsglases, über der Naht zwischen einem Deckel und einem Behälter oder über dem Aufreissverschluss eines Beutels festgelegt worden sind. Beim Öffnen der entsprechenden Verpackung wird die Etikette, die Banderole oder der Siegelstreifen zerstört und damit angezeigt, dass eine Erstöffnung bereits erfolgt ist. Es ist auch möglich, Gegenstände in eine Umverpackung zu füllen oder einzuhüllen, wobei die Umverpackung charakteristische unverwechselbare und nicht kopierbare Merkmale aufweist, welche zeigen, dass das Verpacken des Inhalts bei einem bestimmten Lieferanten erfolgt ist.A tamper evident packaging or packaging aid may serve as a tamper evidence guarantee that allows the customer to recognize that the product he has purchased has actually been manufactured and packaged by the desired producer. A tamper-proof packaging aid can i.a. also be used as a first-opening guarantee, for example in the form of a label, a band or a sealing strip, etc., which are e.g. above a bottle cap or over the closure of a wide mouth jar, over the seam between a lid and a container or over the zipper of a bag. When opening the appropriate packaging, the label, the banderole or the sealing strip is destroyed, indicating that an initial opening has already taken place. It is also possible to fill or wrap articles in an overpack, the overpack having characteristic distinctive and non-duplicable features which show that the packaging of the contents has been done at a particular supplier.
Bekannte fälschungssichere Verpackungen und Produkte sind auf ihrer Oberfläche mit Hologrammen versehen oder weisen Farbcodierungen oder unsichtbare Merkmale auf. Zur Erzielung einer hohen Fälschungssicherheit haben sich in der Praxis u.a. Hologramme bewährt. Beispiele sind Hologrammetiketten oder Deckelfolien mit integrierten Hologrammen. Die Erzeugung von individualisierten Hologrammen ist jedoch mit einem enormen Aufwand verbunden.Well-known forgery-proof packaging and products are on their surface provided with holograms or have color coding or invisible features. In order to achieve a high security against counterfeiting holograms have proven themselves in practice. Examples are hologram labels or lidding films with integrated holograms. The production of individualized holograms is, however, associated with an enormous effort.
Aus dem Artikel von
Der Erfindung liegt die Aufgabe zugrunde, einen Gegenstand der eingangs genannten Art mit einer unter UV-Strahlung sichtbaren Bedruckung zu versehen, die zu einer weiteren Erhöhung der Fälschungssicherheit führt und deren Details für einen Betrachter nicht ohne weiteres erkennbar sind.The invention has for its object to provide an article of the type mentioned with a visible under UV radiation printing, which leads to a further increase in anti-counterfeiting security and their details are not readily apparent to a viewer.
Zu einer ersten erfindungsgemässen Lösung der Aufgabe führt, dass das Bild aus zwei Teilbildem besteht, wobei ein erstes Teilbild in einer rot fluoreszierenden Druckfarbe und das zweite Teilbild in einer grün oder blau fluoreszierenden Druckfarbe als Negativbilder gegenseitig so angeordnet sind, dass die Teilbilder einem gleichzeitig mit jedem Auge durch je einen auf die fluoreszierenden Druckfarben der beiden Teilbilder abgestimmten Farbfilter auf die Teilbilder blickenden Betrachter als dreidimensionales Bild erscheinen.To a first inventive solution of the problem results in that the image consists of two Teilbildem, wherein a first partial image in a red fluorescent ink and the second partial image in a green or blue fluorescent ink as negative images are mutually arranged so that the partial images one at the same time Each eye through each one on the fluorescent inks of the two partial images matched color filter on the partial images look viewer appear as a three-dimensional image.
Die erste erfindungsgemässe Lösung der Aufgabe macht von dem im sichtbaren Bereich des Licht als Anaglyphenverfahren bekannten Phänomen Gebrauch. Diese Methode wird beispielsweise in Mathematiklehrbüchem zur Illustration der Stereometrie oder der sphärischen Trigonometrie eingesetzt.The first solution according to the invention makes use of the phenomenon known in the visible light field as an anaglyphic process. This method is used, for example, in mathematics textbooks to illustrate stereometry or spherical trigonometry.
Der wesentliche Kem dieser Erfindung liegt in der Übertragung des Anaglyphenverfahrens aus dem sichtbaren Bereich des Lichts in den Bereich der UV-Strahlung, wobei folgende wichtige Besonderheit zu beachten ist:
- Bei Bildern, die aus im sichtbaren Licht erkennbaren Farben gedruckt sind, ist es Konvention, für das linke Auge einen Rotfilter zu benutzen. Das linke Auge sieht dann nur das korrespondierende, in grüner oder blauer Farbe gedruckte Teilbild. Für das rechte Auge wird ein Grün- oder Blaufilter benutzt. Das rechte Auge sieht dann nur das korrespondierende, in roter Farbe gedruckte Teilbild.
- Bei fluoreszierenden Farben müssen die Teilbilder negativ gedruckt werden. Zudem gehört zum linken Rotfilter ein korrespondierendes Teilbild mit roter Fluoreszenz, zum rechten Grün- oder Blaufilter ein korrespondierendes Teilbild mit grüner oder blauer Fluoreszenz.
- For images printed in visible colors, it is convention to use a red filter for the left eye. The left eye then only sees the corresponding partial image printed in green or blue. For the right eye, a green or blue filter is used. The right eye then only sees the corresponding partial image printed in red.
- For fluorescent colors, the partial images must be printed negatively. In addition, a corresponding partial image with red fluorescence belongs to the left red filter, to the right green or blue filter a corresponding partial image with green or blue fluorescence.
Die im Zusammenhang mit fluoreszierenden Effekten üblicherweise verwendete UV-Strahlung liegt mit einer Wellenlänge von 365 nm im langwelligen Bereich und wird auch als Schwarzlicht bezeichnet.The UV radiation commonly used in connection with fluorescent effects is at a wavelength of 365 nm in the long-wave range and is also referred to as black light.
Zu einer zweiten erfindungsgemässen Lösung der Aufgabe führt, dass das Bild aus einem ein im wesentlichen nicht zusammenhängendes Störmuster bildenden ersten Teilbild in einer rot fluoreszierenden Druckfarbe und einem ein im wesentlichen zusammenhängendes, eine Information tragendes Muster bildenden zweiten Teilbild in einer grün oder blau fluoreszierenden Druckfarbe besteht, wobei das die Information tragende Muster des zweiten Teilbildes für einen durch einen auf die rot fluoreszierende Druckfarbe des ersten Teilbildes abgestimmten Farbfilter auf die Teilbilder blickenden Betrachter erkennbar ist.To a second inventive solution of the problem results in that the image consists of a substantially non-contiguous disturbing pattern forming the first field in a red fluorescent ink and a substantially contiguous, an information bearing pattern forming second field in a green or blue fluorescent ink in which the information-carrying pattern of the second sub-image can be recognized by a viewer who is looking at the sub-images by means of a color filter matched to the red-fluorescent printing ink of the first sub-image.
Die zweite erfindungsgemässe Lösung der Aufgabe macht ebenfalls von einem im sichtbaren Bereich des Licht bekannten Phänomen Gebrauch, bei dem ein eine Information enthaltendes Muster in einem sehr hellen Grün oder Blau (Cyan) gedruckt wird. Bei Betrachtung durch den Rotfilter erzeugt das Grün oder Blau trotzdem ein kontrastreiches s/w-Bild. Mit einem in kräftigem Rot gedruckten Störmuster verschwindet das grüne oder blaue Muster für einen Betrachter praktisch vollständig oder erscheint zumindest nicht als zusammenhängendes Muster.The second solution according to the invention also makes use of a phenomenon known in the visible light field in which a pattern containing information is printed in a very light green or blue (cyan). When viewed through the red filter, the green or blue still produces a high-contrast b / w image. With a printed in bold red Stuttering pattern, the green or blue pattern disappears for a viewer almost completely or at least does not appear as a coherent pattern.
Bevorzugt fluoresziert die Druckfarbe des ersten Teilbildes in kräftigem Rot und die Druckfarbe des zweiten Teilbildes in Grün oder Blau.Preferably, the printing ink of the first partial image fluoresces in strong red and the printing ink of the second partial image in green or blue.
Die Fälschungssicherheit kann durch entsprechende Wahl der Druckfarben dadurch weiter erhöht werden, dass eine der beiden fluoreszierenden Druckfarben durch UV-Strahlung sowohl im langwelligen (365 nm) als auch in kurzwelligen (254 nm) und die andere fluoreszierende Druckfarbe nur im kurzwelligen (254 nm) Wellenlängenbereich aktiviert wird. Dadurch wird im gebräuchlichen langwelligen UV-Bereich nur ein Teilbild sichtbar, worauf sich der Fälscher eventuell zufrieden gibt. Erst im kurzwelligen UV-Bereich erscheinen beide Teilbilder, die bei der ersten erfindungsgemässen Lösung der Aufgabe als Anaglyph bzw. als dreidimensionales Bild gesehen werden können. Bei der zweiten erfindungsgemässen Lösung der Aufgabe werden die Druckfarben entsprechend so gewählt, dass die grün oder blau fluoreszierende Druckfarbe des zweiten Teilbildes mit dem eine Information enthaltenden Muster nur im kurzwelligen (254 nm) Wellenlängenbereich und die rot fluoreszierende Druckfarbe des ersten Teilbildes mit dem Störmuster sowohl im langwelligen (365 nm) als auch in kurzwelligen (254 nm) Wellenlängenbereich aktiviert wird. Dadurch wird das zweite Teilbild mit dem eine Information enthaltenden Muster nur unter kurzwelliger UV-Strahlung sichtbar. Im gebräuchlichen langwelligen UV-Bereich kann dann nur das erste Teilbild mit dem Störmuster in der rot fluoreszierenden Druckfarbe gesehen werden, was zur Erhöhung der Sicherheit beiträgt.The security against counterfeiting can be further increased by appropriate choice of the printing inks that one of the two fluorescent inks by UV radiation in both the long-wavelength (365 nm) and short-wave (254 nm) and the other fluorescent ink only in the short-wave (254 nm) Wavelength range is activated. As a result, only a partial image is visible in the usual long-wave UV range, whereupon the counterfeiter may be satisfied. Only in the short-wave UV range do both partial images appear, which can be seen as anaglyph or as a three-dimensional image in the first solution according to the invention. In the second inventive solution of the problem, the printing inks are selected accordingly so that the green or blue fluorescent ink of the second field with the pattern containing an information only in the short wavelength (254 nm) wavelength range and the red fluorescent ink of the first field with the interfering pattern both is activated in the long-wavelength (365 nm) as well as in the short-wave (254 nm) wavelength range. As a result, the second partial image with the pattern containing an information is only visible under short-wave UV radiation. In the usual long-wave UV range, only the first partial image with the interference pattern in the red fluorescent printing ink can be seen, which contributes to an increase in safety.
Die Herstellung des erfindungsgemässen Gegenstandes erfolgt nach bekannten Verfahren. Die Fälschungssicherheit wird zusätzlich noch dadurch erhöht, dass das Aufbringen der Teilbilder auf einer Maschine mit hochpräziser Druckmarkensteuerung erfolgen muss.The preparation of the article according to the invention is carried out by known processes. The security against counterfeiting is further increased by the fact that the application of the partial images must be carried out on a machine with high-precision print mark control.
Der erfindungsgemässe Gegenstand kann beispielsweise ein beliebiges Verpackungsmaterial in der Form eines Packstoffes oder Packhilfsmittels sein, welches eine durchsichtige Materialschicht aufweist, wobei zusätzlich erfindungsgemäss Bildmuster aufgebracht sind. Der Packstoff kann starr, halbstarr oder flexibel sein und kann ein Formkörper oder insbesondere ein folienförmiges Material darstellen. Beispiele für Formkörper sind geblasene, tief- und/oder streckgezogene oder getiefte Formkörper, wie Flaschen, Weithalsgefässe, Becher, Schalen oder Bodenteile von Durchdrückpackungen oder Blisterpackungen. Beispiele für folienförmige Materialien sind Metallfolien, wie Aluminium-, Stahl-, Kupfer-, Silber- oder Goldfolien. Weitere Beispiele für follenförmige Materialien sind Papiere, wie Seidenpapier mit einem Flächengewicht von 20 bis 30g/m2 oder Hochweisspapier mit einem Flächengewicht von 40 bis 60g/m2, Karton, Halbkarton oder dgl. Bedeutsam sind insbesondere kunststoffhaltige Folien, z.B. auf der Basis von Polyolefinen, wie Polyethylenen oder Polypropylenen, Polyamiden, Polyvinylchlorid, Polyestem, wie Polyalkylenterephthalaten und insbesondere Polyethylenterephthalat. Die kunststoffhaltigen Folien können Monofolien aus Kunststoffen, Laminate aus zwei oder mehreren Kunststofffolien, Laminate aus Metall- und Kunststofffolien, Laminate aus Papieren und Kunststofffolien oder Laminate aus Papieren und Metall- und Kunststofffolien sein. Die einzelnen Kunststofffolien können eine Dicken von beispielsweise 12 bis 200µm und die Metallfolien von 12 bis 100 µm aufweisen. Die einzelnen Schichten der folienförmigen Materialien können mittels Klebstoffen, Kaschierklebem, Haftvermittlem und/oder durch Extrusionsbeschichten, Coextrusion oder Kaschieren usw. aneinander festgelegt werden. Als Kunststofffolien bevorzugt sind nicht orientierte oder axial oder biaxial orientierte Monofolien oder Laminate aus zwei oder mehreren nicht orientierten oder axial oder biaxial orientierten Folien aus Kunststoffen auf der Basis von Polyolefinen, wie Polyethylenen oder Polypropylenen, Polyamiden, Polyvinylchlorid, Polyestern, wie Polyalkylenterephthalaten und insbesondere Polyethylenterephthalat.The article according to the invention can be, for example, any packaging material in the form of a packaging material or packaging auxiliary, which has a transparent material layer, wherein image patterns are additionally applied according to the invention. The packaging material may be rigid, semi-rigid or flexible and may be a molded article or, in particular, a film-shaped material. Examples of moldings are blown, deep-drawn and / or stretched or deep-drawn moldings, such as bottles, wide-necked vessels, cups, bowls or bottom parts of blister packs or blister packs. Examples of film-shaped materials are metal foils, such as aluminum, steel, copper, silver or gold foils. Further examples of sheet-like materials are papers, such as tissue paper with a basis weight of 20 to 30 g / m 2 or white and white paper with a basis weight of 40 to 60 g / m 2 , cardboard, semi-board or the like. Particularly important are plastic-containing films, eg based on Polyolefins, such as polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters, such as polyalkylene terephthalates and in particular polyethylene terephthalate. The plastic-containing films may be monofilms of plastics, laminates of two or more plastic films, laminates of metal and plastic films, laminates of papers and plastic films or laminates of papers and metal and plastic films. The individual plastic films may have a thickness of, for example, 12 to 200 .mu.m and the metal foils 12 to 100 .mu.m. The individual layers of the film-shaped materials can be fixed to one another by means of adhesives, laminating adhesives, adhesion promoters and / or by extrusion coating, coextrusion or laminating. Non-oriented or axially or biaxially oriented monofilms or laminates of two or more unoriented or axially or biaxially oriented films based on polyolefins, such as polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters, such as polyalkylene terephthalates and in particular polyethylene terephthalate, are preferred as the plastic films ,
Die vorstehend erwähnten Verpackungsmaterialien können die erfindungsgemässen Gegenstände in der Form von Packstoffen oder Packhilfsmitteln bilden. Beispielsweise können aus folienförmigen Packstoffen durch Ausstanzen und Siegeln Beutel, Sachets, Einwickler, Taschen usw. hergestellt werden. Folien können durch Tief- und/oder Streckziehen zu Formpackungen oder Formkörpern, wie Bodenteilen von Durchdrück- oder Blisterpackungen oder zu Weithalsgefässen, Menuschalen, Gobelets, Bechern usw. verformt werden. Es können aus den Folien z.B. Tuben (Laminattuben) oder Deckel für Formpackungen hergestellt werden. Aus beispielsweise kartonhaltigen Substraten können Schachteln, wie Faltschachteln, hergestellt werden. Es ist auch möglich, z.B. Flaschen, aus Kunststoffen geblasen, oder vorgeformte Formpackungen als Substrate zu verwenden und die erfindungsgemässe Materialschicht darauf anzubringen. Verschlüsse, Öffnungen, Nähte, Nähte zwischen einem Bodenteil und dem dazugehörigen Deckel usw. können mit einem erfindungsgemässen Packhüfsmittel in Form einer Etikette, eines Siegelstreifens, einer Banderole, eines Garantiesiegels oder einer Überschliessung versehen werden. Diese letztgenannten Packhilfsmittel liegen in der Regel folienförmig vor und werden auf dem entsprechenden Behälter über der Öffnung und am angrenzenden Behälterteil fixiert, wie beispielsweise festgeklebt, angeschweisst, aufgebördelt oder aufgeschrumpft usw. Das Packhilfsmittel weist die erfindungsgemässe durchsichtige Materialschicht und die durch diese in Abstand gehaltenen Bildmuster auf. Der erfindungsgemässe Aufbau der Oberfläche bzw. eines Oberflächenbereichs des Gegenstandes führt zu der gezielt angestrebten optischen Erscheinung bei Änderung des Betrachtungswinkels. Eine Fälschung durch Fotokopieren und Verwendung der Fotokopie als Originalitäts- oder Herstellergarantie wäre sofort und leicht erkennbar, da eine Änderung des Betrachtungswinkels den bei erfindungsgemässem Aufbau auftretenden optischen Effekt nicht zeigt. Damit Packhilfsmittel, beispielsweise Siegeistreifen oder Banderolen, vom Verbraucher leicht gebrochen werden können, kann es zweckmässig sein, Anreisshilfen wie Schwächungen, Kerben oder Abreisszungen vorzusehen. Es können als Bestandteil von Packstoffen oder Packhilfsmitteln auch leicht einreissbare oder durchstossbare Folien, wie mit Füllstoffen angereicherte Kunststofffolien oder aus zwei schlecht verträglichen Kunststofffolien hergestellte Folien angewendet werden.The above-mentioned packaging materials may form the articles of the present invention in the form of packaging materials or packaging aids. For example, from foil-shaped packaging materials by punching and sealing bags, sachets, wrappers, bags, etc. can be made. Films can be deformed by deep drawing and / or ironing to form packages or moldings, such as bottom parts of blister packs or blister packs or wide-mouth vessels, dishes, goblets, cups, etc. For example, tubes (laminate tubes) or covers for mold packs can be produced from the films. From, for example, carton-containing substrates, cartons, such as folding cartons, can be produced. It is also possible, for example bottles, blown from plastics, or to use preformed moldings as substrates and to attach the inventive material layer thereon. Closures, openings, seams, seams between a bottom part and the associated lid, etc., can be provided with a packaging aid according to the invention in the form of a label, a sealing strip, a banderole, a warranty seal or a closure. These latter packaging aids are generally film-shaped and are fixed on the corresponding container over the opening and adjacent container part, such as glued, welded, crimped or shrunk, etc. The packaging aid has the transparent material layer according to the invention and the image pattern held at a distance therefrom on. The construction according to the invention of the surface or of a surface region of the object leads to the targeted optical appearance when the viewing angle changes. Falsification by photocopying and using the photocopy as a guarantee of originality or manufacturer would be immediately and easily recognizable, since a change in the viewing angle does not show the optical effect occurring in the structure according to the invention. So that packaging aids, for example Siege strips or banderoles, can easily be broken by the consumer, it may be expedient to provide marking aids such as weakenings, notches or tear-offs. It is also possible to use, as a constituent of packaging materials or packaging auxiliaries, easily tear-in or puncturable films, such as plastic films enriched with fillers or films produced from two poorly compatible plastic films.
Neben der bereits erwähnten Verwendung des erfindungsgemässen Gegenstandes in der Form einer Verpackung, eines Packstoffes oder eines Packhilfsmittels ist ein weiteres Anwendungsgebiet die fälschungssichere Herstellung von Wertpapieren, Eintrittskarten und dergleichen Dokumenten, wobei neben der fälschungssicheren Ausgestaltung auch dekorative Spezialeffekte erzeugt werden können.In addition to the already mentioned use of the article according to the invention in the form of a packaging, a packaging material or a packaging aid, another field of application is the forgery-proof production of securities, tickets and similar documents, whereby not only the forgery-proof design but also decorative special effects can be generated.
