Description
Die Erfindung bezieht sich auf die Polygrafie und betrifft insbesondere ein Druckverfahren, das als Orloffdruck bekannt ist und hauptsächlich zum Auftragen eines Schutzmusters beim Druck von Wertdokumenten, im besonderen von Geldzeichen, angewendet wird.The invention relates to the polygraphy and relates in particular a printing process called Orloffdruck is known and mainly for applying a protective pattern in the printing of value documents, in particular of Money sign, is applied.
Das Orloff-Mehrfarbendruckverfahren basiert auf dem Einfärben einer Sammeldruckform mit Hilfe von Farbschablonen, wobei die Sammeldruckform und die Farbschablonen jeweils auf einem Formzylinder und auf Schablonenwalzen angeordnet werden. Der Antrieb der Schablonenwalzen von dem Formzylinder erfolgt mittels eines Zahngetriebes. Solch ein Getriebe gewährleistet eine fixierte Lage der Schablonen in bezug auf die Sammeldruckform, welche Lage während des Druckvorgangs beibehalten wird.The Orloff multi-color printing process is based on dyeing a collective printing form with the help of color stencils, wherein the collective printing form and the color stencils respectively a form cylinder and stencil rollers are arranged. The drive of the stencil rollers from the forme cylinder takes place by means of a toothed gear. Such a transmission ensured a fixed position of the templates with respect to the collective printing form, which position during the printing process is maintained.
Ein Orloff-Mehrfarbenbild wird durch Erzeugung einer kontinuierlich gefärbten Linie mit Farbübergang formiert. Hier wird unter dem Farbenübergang einer derartigen Linie die Färbung ihrer verschiedenen Abschnitte in entsprechende Farben verstanden. Dabei kennzeichnet sich die Grenze des Übergangs eines Linienabschnitts der einen Farbe in einen Linienabschnitt der anderen Farbe durch das Fehlen von Mischzonen dieser Farben im indirekten Orloffdruck und durch Vorhandensein einer minimalen Mischzone der Farben im direkten Orloffdruck. Somit decken alle Farbschablonen bei deren Auflegen auf die Sammeldruckform die Gesamtfläche des malerischen Feldes der Sammeldruckform vollständig zu, ohne daß verschiedene einzelne Farbflächen aufeinandergelegt werden.An Orloff multicolor image is created by creating a continuously colored line formed with color transition. Here is under the color transition of such a line the coloring of their various sections in appropriate Colors understood. This marks the limit of Transition of a line segment of one color into one Line section of the other color due to the absence of mixing zones these colors in indirect Orloffdruck and by presence a minimum mixing zone of colors in direct Orloffdruck. Thus, all color templates cover when they are laid on the collective printing the total area of the picturesque Field of the collective printing form completely, without that different individual color surfaces are stacked.

Die Lage der Schablonen ist in bezug auf die Sammeldruckform durch den von dem Formzylinder erfolgenden Zahnradantrieb der Schablonenwalzen fixiert, so daß auf diese Weise während des Druckvorgangs die Möglichkeit einer Verschiebung der Schablonenwalzen relativ zum Formzylinder sowohl in der Axial- als auch in der Umfangsrichtung ausgeschlossen ist.The closest analogue solution was the one in the Application EP 0092887 A1 disclosed method of indirect and direct Orloff multicolor printing adopted Coloring the collective printing plate of a forme cylinder with the help of of stencil rollers whose color stencils comprise clay plates different configuration are. The location of the templates is with respect to the collective printing form by that of the forme cylinder taking place gear drive of the stencil rollers fixed so that in this way during the printing process the Possibility of shifting the stencil rollers relative to the forme cylinder in both the axial and in the circumferential direction is excluded.
Der Hauptnachteil des existierenden Verfahrens ist das Fehlen einer Mischzone zwischen zwei Abschnitten unterschiedlicher Farben im indirekten Orloffdruck und eine geringe Länge dieser Zone (unzureichend für die Erzielung einer Mischfarbe) im direkten Orloffdruck, was es nicht gestattet, dadurch das Farbgamma und den Farbenreichtum der kontinuierlich gefärbten Linie und demnach des Orloffmusters selbst zu vergrößern.The main disadvantage of the existing method is that Lack of a mixing zone between two sections of different Colors in the indirect Orloffdruck and a small one Length of this zone (insufficient for the achievement of a Mixed color) in direct Orloff printing, which does not allow thereby the color gamma and the color wealth of the continuous colored line and therefore of the Orloff pattern itself enlarge.

Das vorgeschlagene Verfahren sieht auch den Einbau einer zusätzlichen speichernden Schablonenwalze mit Zwangsbewegung innerhalb von Größen vor, die den angegebenen Bewegungsgrößen entsprechen. Die genannte Walze stellt eine Tonplatte gemäß dem Format des malerischen Feldes der Sammeldruckform dar und nimmt auf bzw. überträgt das Mehrfarbenbild während ihres Kontaktes mit den Gummitüchern eines Sammel-Gummizylinders.The proposed method also provides for the installation of a additional storing stencil roller with forced movement within sizes that are the specified motion quantities correspond. The said roller provides a tone plate according to the format of the pictorial field of the collective printing form and picks up or transfers the multicolor image during her Contact with the blankets of a collection rubber cylinder.
Die Grenzzone der Farbschablone wird vorwiegend durch Einführung einer nach der Ausfüllfläche abnehmenden, kontinuierlichen oder gestuften Rasterskala vergrößert, deren Linearabmessungen und Gradationskennlinien die Länge der Zone und die Stetigkeit des Farbenübergangs bestimmen und die als Punkt- oder lineare Skala ausgebildet ist, wobei die Rasterliniatur der erwähnten Skala in einem Bereich von Werten zwischen 8 und 40 lin/cm liegt.The border zone of the color template is predominantly through Introduction of a decreasing after the filling surface, continuous or stepped grid scale, whose Linear dimensions and gradation curves the length of the zone and determine the continuity of the color transition and the as Point or linear scale is formed, wherein the Rasterliniatur the mentioned scale in a range of values between 8 and 40 lin / cm.
Es wird vorgesehen, daß die Gradationskennlinie der gestuften Rasterskala den Ausfüllflächen der Felder der Rasterzelle von 80, 60, 40 und 20% entspricht. Zur Bildung von drei optischen Dichten in den Grenzen einer der Grundfarben der kontinuierlich gefärbten Linie wird eine Rasterskala mit einer Ausfüllfläche der Felder der Rasterzelle von 10, 40 und 80% verwendet.It is envisaged that the gradation characteristic of the stepped Raster scale the filling surfaces of the fields of the grid cell of 80, 60, 40 and 20%. To the formation of three optical densities within the boundaries of one of the primary colors the continuously colored line is using a grid scale a fill area of the fields of the grid cell of 10, 40 and 80% used.
Auch wird gemäß dem Verfahren für jedes Paar der Grunddruckfarben ein bestimmtes Verhältnis der Werte des Viskositätsindexes der Farben bei deren Gesamtbereich der Werte von 2 bis 12,5 Pa·s (20 bis 125 Poise) passend ausgewählt.Also, according to the method, for each pair of the basic inks a certain ratio of the values of the viscosity index the colors at their total range of values from 2 to 12.5 Pa · s (20 to 125 poise) selected appropriately.
Ein technisches Resultat, das bei der Nutzung der Erfindung erzielt werden kann, besteht in der Schaffung neuer künstlerischer und technologischer Möglichkeiten des Aufbaus des eigentlichen mehrfarbigen Orloff-Musters, da die Herstellung einer Zone des stetigen Farbenübergangs im Schutzmuster es erlaubt, einen Iriseffekt in den Grenzen der vollständigen Erfassung des Bildes in der Umfangsrichtung zu erzeugen.A technical result in the use of the invention can be achieved, is the creation of new ones artistic and technological possibilities of construction the actual multicolor Orloff pattern, since the production a zone of continuous color transition in the protective pattern it allows an iris effect within the limits of the complete Capture of the image in the circumferential direction too produce.
Die Iriszonen des Farbenübergangs vergrößern den gesamten Farbenreichtum des Musters dank einer Komplementärfarbe und dank Farbtönungen ohne Begrenzung ihrer Orientierung über den Umfang und die Länge solcher Zonen.The iris zones of the color transition increase the total Rich in colors of the pattern thanks to a complementary color and thanks to tints without limiting their orientation about the extent and length of such zones.
Insgesamt weist das mehrfarbige Orloff-Muster mit dem Iriseffekt höhere Schutzeigenschaften auf, den Ausschluß einer Wiedergabe dieses Musters auf Farbkopier- und Vervielfältigungsautomaten mit einbegriffen, was in der Produktion von Wertpapieren (Banknoten) maßgeblich ist.Overall, the multi-colored Orloff pattern with the Iris effect higher protection properties, the exclusion a reproduction of this pattern on color copying and duplicating machines including what's in production of securities (banknotes).
In Fig. 1 sind die Grundsätze der Formierung einer Zone der stetigen Mischung zweier Farben unter Bildung einer Komplementärfarbe veranschaulicht.In Fig. 1, the principles of forming a zone the steady mixture of two colors to form a Complementary color illustrated.
Nachstehend wird ein Ausführungsbeispiel des Verfahrens angeführt.Below is an embodiment of the method cited.
Den Schablonenwalzen wird beim Einfärben der Sammeldruckform eines Formzylinders die Möglichkeit einer ständigen zyklischen hin- und hergehenden Zwangsbewegung (M) relativ zum Formzylinder in der Axial- und der Umfangsrichtung gegeben, ohne daß deren von dem Formzylinder erfolgender Zahnradantrieb gestört wird. Wie Untersuchungen ergaben, muß zur Herstellung einer Mischzone mit mindestens einer Komplementärfarbe die Größe dieser Bewegung der Schablonenwalze in einem Bereich von Werten zwischen 0,2 und 4,0 mm liegen, was einer Verschiebung der Schablone relativ zur zentralen Lage in den Grenzen von 0,1 bis 2,0 mm in beiden Richtungen entspricht. Dabei wurde festgestellt, daß die Zyklizität einer solchen Bewegung aus einer Endlage in die andere für ein Verhältnis der Durchmesser des Schablonenzylinders und des Sammel-Gummizylinders gleich 1 : 2 zwei bis zehn volle Umdrehungen des Sammel-Gummizylinders betragen soll, d.h., die Verhältnisse zwischen der Anzahl der rückläufigen Bewegungen und der Drehzahl der Schablonenzylinder sind irrationale Zahlen, die im Bereich von 2 bis 10 liegen.The stencil rollers are when coloring the collective printing plate a forme cylinder the possibility of a permanent cyclic reciprocating forced motion (M) relative given to the forme cylinder in the axial and circumferential directions, without that of the forme cylinder successful gear drive is disturbed. Research has shown that Production of a mixing zone with at least one complementary color the size of this movement of the stencil roller in a range of values between 0.2 and 4.0 mm, which is a displacement of the template relative to the central location in the limits of 0.1 to 2.0 mm in both directions. It was found that the cyclicity of a such movement from one end position to the other for one Ratio of the diameters of the stencil cylinder and the Collection rubber cylinder equal to 1: 2 two to ten full turns of the collecting rubber cylinder, that is, the Relationships between the number of retrograde movements and the speed of the stencil cylinders are irrational Numbers ranging from 2 to 10.
Eine der möglichen Varianten der Zwangsbewegung der Schablonenfarbwalzen kann der Einsatz eines Kurvengetriebes sein.One of the possible variants of the forced movement of Stencil paint rollers can be the use of a cam gear be.
Das Verfahren sieht auch eine zusätzliche Übertragung der Farben durch Einführung einer zusätzlichen speichernden Schablonenwalze mit Zwangsverreibung innerhalb der vorstehend angegebenen Größen vor, die eine gleichmäßige Mischung der Farben in der Zone ihres stetigen Übergangs gewährleistet. Die speichernde Schablone stellt eine Tonplatte dar, die nach dem Format (der Größe) des malerischen Feldes gleich dem Flächeninhalt der Sammeldruckform ist. Die speichernde Schablonenwalze besitzt kein Farbwerk und nimmt auf bzw. überträgt das Mehrfarbenbild während ihres Kontaktes mit den Gummitüchern des Sammel-Gummizylinders. Im geraden Orloff-Mehrfarbendruck hängt der Einbau einer speichernden Schablonenwalze mit Zwangsverreibung mit der Installation einer zusätzlichen Schablone - der Tonplatte - als Folge der Anordnung der Sammeldruckform und der Farbschablonen auf ein und demselben Formzylinder zusammen.The procedure also sees an additional transmission the colors by introducing an additional storing Forced roller stencil roller within the above given sizes, which is a uniform mixture ensures the colors in the zone of their steady transition. The saving template represents a clay plate representing the format (size) of the picturesque field is equal to the area of the collective printing form. The saving Stencil roller has no inking and picks up or transmits the multi-color image during their contact with the blankets of the collection rubber cylinder. In the straight Orloff multi-color printing depends on the incorporation of a storing Forced roller stencil roller with the installation an additional template - the clay plate - as a result the arrangement of the collective printing plate and the color stencils one and the same form cylinder together.
In die Konstruktion der Farbschablone ist in deren Grenzzone eine Rasterskala eingeführt, deren Dichte durch unterschiedliche Ausfüllfläche der Rasterzelle vorgegeben wird. In bezug auf die Grenze der Schablone nimmt diese Fläche ab, wobei sie eine Wertefolge von 100 bis 0% bildet. Die Rasterskala selbst kann gestuft oder kontinuierlich abnemend sein. Die Abmessungen und Kennlinien dieser Rasterskala sind in der Bildung und Formierung der Zone der stetigen Farbmischung in der kontinuierlich gefärbten Linie maßgeblich.In the construction of the color stencil is in its border zone introduced a grid scale, their density by different Fill area of the grid cell is specified. With respect to the boundary of the template, this area decreases, where it forms a value sequence of 100 to 0%. The grid scale itself can be stepped or continuously decreasing. The dimensions and characteristics of this grid scale are in the formation and formation of the zone of continuous color mixing in the continuously colored line.
Die Rasterliniatur einer solchen Skala liegt in einem Bereich von Werten zwischen 8 und 40 lin/cm. Die Breite der Rasterübergänge - VAR von 0 bis 50 mm.The raster line of such a scale lies in one Range of values between 8 and 40 lin / cm. The width of the Grid transitions - VAR from 0 to 50 mm.
Die Länge der Zone eines stetigen Farbenübergangs wird durch die Gesamtgröße der Rasterskala bestimmt und liegt in einem Wertebereich von 1 bis 25 mm und darüber. Die eigentliche Stetigkeit des Farbenübergangs in dieser Zone hängt von den Gradationskennlinien der Rasterskala ab. Diesen Anforderungen entspricht z.B. eine Fünffeldskala mit einer Ausfüllfläche der Felder von 80, 60, 40 und 20%.The length of the zone of a continuous color transition becomes determined by the total size of the grid scale and is located in a value range of 1 to 25 mm and above. The real one Continuity of the color transition in this zone depends from the gradation characteristics of the raster scale. These requirements corresponds e.g. a five-field scale with a Fill area of the fields of 80, 60, 40 and 20%.
Die Anwendung einer Rasterskala beispielsweise mit einer Ausfüllfläche von 10, 40, 80% gestattet es, mindestens drei optische Dichten in den Grenzen einer Grundfarbe der mehrfarbigen kontinuierlich gefärbten Linie zu erhalten. Hier wird die unterschiedliche optische Dichte der Linie durch Verringerung der Dicke der Farbschicht auf dieser infolge einer Änderung der Ausfüllfläche der Rasterskala der betreffenden Farbschablone erzeugt.The application of a raster scale, for example with a fill-in area of 10, 40, 80% allows, at least three optical densities within the boundaries of a primary color of to obtain multicolored continuously colored line. Here is the different optical density of the line by reducing the thickness of the paint layer due to this a change of the fill area of the raster scale of generated color template.
Die Stetigkeit der Farbmischung und der Offenbarung der Zone mit der Komplementärfarbe in der kontinuierlich gefärbten Linie hängt nicht nur von den Farbcharakteristiken der Farben, sondern auch von der Auswahl der Viskositätsgrade der diese Zone bildenden Grunddruckfarben ab. Die Auswahl der Viskositätsindexe der Druckfarben wird in einem Bereich von Werten zwischen 2 und 12,5 Pa·s (20 und 125 Poise) vorgenommen. Beispielsweise sind die Werte der Viskosität zweier Druckfarben, die die Zone eines stetigen Farbenübergangs bilden, für den indirekten Orloffdruck jeweils gleich 7 und 8 Pa·s (70 und 80 Poise).The continuity of color mixing and the disclosure of Zone with the complementary color in the continuously colored Line does not just depend on the color characteristics of the Colors, but also on the choice of viscosity grades of the basic printing inks forming this zone. The selection the viscosity indexes of the printing inks is in one range of values between 2 and 12.5 Pa · s (20 and 125 poise). For example are the values of the viscosity of two inks, the form the zone of a continuous color transition for which indirect Orloff pressure equal to 7 and 8 Pa · s (70 and 80 poise).
Für den direkten Orloff-Mehrfarbendruck, bei dem die
Sammeldruckform und die Farbschablonen auf ein und demselben
Formzylinder angeordnet sind, wird die Zone der stetigen
Farbmischung in der kontinuierlich gefärbten Linie durch
die Zwangsbewegung der Sammelwalzen nach Anspruch 1 und durch
den Einbau einer zusätzlichen, als Tonplatte ausgebildeten
Schablone und einer speichernden Sammelwalze mit Zwangsbewegung

Und die Zwangsbewegung der Schablonenwalzen führt unter
der Bedingung der Erfüllung der Forderungen der angemeldeten
Ansprüche 1, 2, 3, 4 dazu, daß auf der kontinuierlich gefärbten
Linie L Farbmischungszonen 4a, 4b und 4c gebildet
werden und eine Zone 4b der Komplementärfarbe (bedingt auf
dem Abzug 4 gezeigt) erscheint. Die volle Farbenreihe unter
Berücksichtigung der Farbmischzone auf der kontinuierlich
gefärbten Linie ist im angeführten Beispiel durch den folgenden
stetigen Farbenübergang repräsentiert: blau - blaurot
- violett - rotblau - rot.And the forced movement of the stencil rollers sets
the condition of fulfillment of the claims of the notified
Somit wird gemäß der vorliegenden Erfindung in den Strukturbestandteil des Orloffdruck-Musters - die kontinuierlich gefärbte Linie L - die Zone N eines stetigen Farbenübergangs von einem Farbabschnitt zum anderen Farbabschnitt eingeführt. Dabei wird der Iriseffekt im Muster innerhalb der vollen Erfassung der Orientierungsrichtungen am Kreisumfang gebildet. Auf diese Weise hängt diese Zone des stetigen Farbenübergangs in der kontinuierlich gefärbten Linie nicht von der Orientierung derselben in bezug auf die Achse des Formzylinders der Druckmaschine ab.Thus, according to the present invention in the Structural component of the Orloffdruck pattern - the continuous colored line L - the zone N of a continuous color transition from one color section to the other color section introduced. The iris effect in the pattern is within the full detection of the orientation directions on the circumference educated. In this way, this zone depends on the steady Color transition in the continuous colored line not from the orientation of the same with respect to the axis of the forme cylinder of the printing press.
Claims (5)
- Orloff multicolour printing process, comprising the inking of the combined printing forme of a forme cylinder by means of stencil cylinders that are connected to the latter through a toothed gear, characterised in that the inking of the combined printing forme of the forme cylinder by means of stencil cylinders is achieved by imparting the latter a forced cyclical reciprocating movement in the axial and the circumferential direction relative to the forme cylinder without disturbing their gearwheel actuation by the latter, the magnitude of the reciprocating movement of the stencil cylinders being comprised in a range of values of 0.2 to 4.0 mm while the ratios of the number of backward movements to the rotational speed of the stencil cylinders are irrational numbers comprised in the range of 2 to 10.
- Process according to claim 1, characterised in that an additional, storing stencil cylinder is incorporated which takes up and/or transfers the coloured image during its contact with the rubber blankets of a combined blanket cylinder and represents a tint plate according to the format of the image area of the combined printing forme, the mentioned storing stencil cylinder being imparted a forced movement within magnitudes corresponding to the indicated magnitudes of movement of the stencil cylinders.
- Process according to any one of claims 1, 2, characterised in that a continuous or graduated halftone scale of diminishing area coverage is introduced in the border zone of the colour stencil, wherein the linear dimensions and gradation curves of the halftone scale determine the length of the zone and the continuity of the colour transition and which is in the form of a dot or a linear scale, the screen lineature of the mentioned scale being comprised in a range of values of 8 to 40 lin/cm.
- Process according to claim 3, characterised in that the gradation curve of the graduated halftone scale is chosen in accordance with the respective area coverage of the patches of the halftone cell of 80, 60, 40, and 20 %.
- Process according to any one of claims 1 to 4, characterised in that for each pair of the primary printing colours, a certain ratio of the values of the viscosity index of each ink is adequately chosen within the total range of their values from 2 to 12.5 Pa·s (20 to 125 Poise).
