Die Figur 1 zeigt ein Druckwerk 1 einer Mehrfarben-Bogenoffsetrotationsdruckmaschine. Jedes
Druckwerk 1 enthält als bogenführenden Zylinder einen Druckzylinder 2 und einen Übergabezylinder
3 und als druckbildübertragenden Zylinder einen Plattenzylinder 4 und einen Gummizylinder 5.FIG. 1 shows a
Jedem Druckformzylinder 4 ist ein Farbwerk 6 und ein Feuchtwerk 7 zugeordnet. Auf dem Plattenzylinder
4 kann auch eine Druckplatte 11 oder ein Sleeve 12 aufgespannt sein (siehe hierzu die Figuren
2 und 3).An inking unit 6 and a
Dem Plattenzylinder 4 kann weiterhin zum Auftragen der Beschichtung in der Druckmaschine eine
als Kammerrakel/Rasterwalzen-Kombination ausgeführte Beschichtungseinrichtung 8 und eine Bebilderungseinrichtung
91 zugeordnet werden. Die Bebilderungseinrichtung 91 zur Bebilderung des
Plattenzylinders 4 bzw. der Druckplatte 11 ist auf der Basis eines thermischen Ablations-Lasers
ausgeführt. Das Material kann aber auch thermisch auf eine andere Art abgetragen werden, z.B.
durch eine thermisch arbeitende Erodiereinrichtung (Funkenerosion).The
In der Figur 2 wird eine erste Variante gezeigt, bei der die Oberfläche 41 des Plattenzylinders 4 als
Druckbildträger dient. Dabei befindet sich auf der vorzugsweise aus Chrom, Aluminium oder Keramik
bestehenden wasseraufnehmenden Oberfläche 41 des Plattenzylinders 4 eine farbaufnehmende,
geschlossene und mechanisch stabile Beschichtung 101 in einer Stärke von maximal 2¼m. Ein Material
für diese Beschichtung 101 kann zum Beispiel ein Polymer sein, das durch die Beschichtungseinrichtung
8 inline aufgebracht und durch einen hier nicht dargestellten Trockner getrocknet wird.FIG. 2 shows a first variant, in which the
In Figur 3 wird eine weitere Variante gezeigt. Hier ist die Beschichtung 102 auf einem Druckbildträger
aufgebracht, der in Form einer Druckplatte 11 oder in Form eines Sleeves 12 auf der Oberfläche des
Plattenzylinders 42 aufgezogen ist. Dabei ist die Oberfläche der Druckplatte 11 oder die Oberfläche
des Sleeves 12 farbaufnehmend. Die auf die Druckplatte 11 oder den Sleeve 12 aufgebrachte Beschichtung
102 hat analoge Eigenschaften zu der unter Figur 2 erläuterten Beschichtung 101.Another variant is shown in FIG. Here the

Allen oben genannten Ausführungen ist gemeinsam, dass die Beschichtung 10, 101, 102 hinsichtlich
ihrer Farbaufnahmefähigkeit zum Druckbildträger 4, 11, 12 entgegengesetzte Eigenschaften aufweist.
Die Beschichtung 10, 101, 102 kann aus einem Polyester oder einem anderen geeigneten
kostengünstigen Stoff mit den geforderten Eigenschaften bestehen. In jedem Fall sind in die Beschichtung
10, 101, 102 neben den bekannten Sensibilisatoren Sauerstoffdonatoren in homogener,
mikroskopisch feiner Verteilung eingebracht. Diese Sauerstoffdonatoren werden entweder im Zuge
der Herstellung dieses Werkstoffs eingebracht oder werden beim Beschichten in die Beschichtung
10, 101, 102 dispergiert.All of the above-mentioned designs have in common that the
Bevorzugte Sauerstoffdonatoren sind Chlorate. Insbesondere Kaliumchlorat ist für diese Zwecke besonders geeignet. Es ist aber auch möglich, Salpeterverbindungen, Peroxide und ähnliche Verbindungen einzusetzen, die ähnlich den oben genannten Materialien Sauerstoff in lockerer Bindung enthalten.Preferred oxygen donors are chlorates. Potassium chlorate in particular is for these purposes particularly suitable. However, it is also possible to use nitric compounds, peroxides and similar compounds use the oxygen in a loose bond similar to the materials mentioned above contain.
Beim Energieeintrag wird eine fokussierbare Bebilderungseinrichtung 91, 92 eingesetzt. durch einen
thermischen Laser (siehe hierzu die Figuren 2 und 3) oder durch ein erodierendes Werkzeug reagiert
der Sauerstoff mit dem Beschichtungsmaterial. Es kommt zu lokal begrenzten exothermen Reaktionen.
Diese Reaktion bleibt, bedingt durch die geringe Stärke der Schicht, örtlich begrenzt, da
das Grundmaterial der Reaktion Wärme entzieht. Das Material an diesen Stellen verbrennt
rückstandslos, so dass keine Nachbehandlung erforderlich wird.A
Um die Bildmotive nach dem Druckvorgang zu löschen, entfalten die eingelagerten Sauerstoffdonatoren
ebenfalls eine vorteilhafte Wirkung. Mit einem Flächenlaser oder mit anderen geeigneten Einrichtungen
erfolgt ein großflächiger Energieeintrag, so dass die Beschichtung auf dem Druckbildträger
4, 11, 12 rückstandslos verbrennen kann.In order to delete the image motifs after the printing process, the embedded oxygen donors unfold
also a beneficial effect. With a surface laser or with other suitable devices
there is a large energy input, so that the coating on the
In der Figur 4 ist ein weiteres Ausführungsbeispiel dargestellt. Dabei wird von einer Zusammensetzung
der Beschichtung 103 ausgegangen, die weitgehend der unter den oben genannten Ausführungsbeispielen
beschrieben Beschichtung entspricht. Im Gegensatz zu diesen ist der Sauerstoff
aber nicht in Form von Sauerstoffdonatoren in die Beschichtung 103 eingebunden, sondern wird an
die aktuelle Wirkungsstelle der Bebilderungseinrichtung 92 herangebracht. Das erfolgt, wie aus der
Figur 4 ersichtlich, durch eine Sauerstoffsonde 922, die an dem Grundkörper 921 der Bebilderungseinrichtung
92 angeordnet ist. Auch hier kommt es zu lokal begrenzten exothermen Reaktionen.
