摘要:
Die Erfindung betrifft eine Vorrichtung (10) zum Dekorieren von Behältern (12) mit einem Plattenzylinder (20), die eine vollflächige oder teilweise flächige Druckplatte (22) oder eine Rasterdruckplatte trägt und mit einem Gummituchzylinder (16), der auf seiner Umfangsrichtung aufeinanderfolgend eine Mehrzahl von Gummitüchern (18) trägt. Der Gummituchzylinder (16) ist bezüglich des Plattenzylinders (20) so angeordnet, dass die Gummitücher (18) mit dem Plattenzylinder (20) abrollend im Eingriff stehen. Die Gummitücher (18) sind mit Druckbildern (24) versehen, die von erhabenen (d.h. nicht-vertieften) Bereichen (26) und dazwischen liegenden, vertieften Bereichen gebildet sind. Wenigstens ein Gummituch (18) weist wenigstens eine großflächigere Vertiefung (30) mit einer Ausdehnung von mehr als 3 mm auf, die gegenüber den erhabenen Bereichen (26) stärker vertieft ist, d.h. eine größere Gravurtiefe aufweist, als kleinflächigere Vertiefungen (28) (z.B. zwischen einzelnen Rasterpunkten) mit einer Ausdehnung von weniger als 0,5 mm.

摘要:
A method of manufacturing a pattern on a substrate web is disclosed, comprising: providing a production tool having a surface relief structure of elevations and depressions, the elevations corresponding to the desired pattern to be applied to the substrate web. A curable material is applied to the elevations of the surface relief structure on the production tool. The applied curable material on the surface relief structure is brought into contact with a substrate web at a first location. The substrate web and surface relief structure are transported together in contact from the first location to a second location, the first and second locations being spaced from one another along the transport direction of the substrate web. The substrate web is separated from the surface relief structure at the second location whereupon the curable material forming the pattern is affixed to and carried by the substrate web. The curable material on the substrate web is cured by exposure to at least one curing energy source, either while the substrate web and surface relief structure are in contact between the first and second locations and/or after the substrate web has been separated from the surface relief structure at the second location.
摘要:
A method for providing a pattern, such as printed lines, is carried out by applying ink to a surface of a substrate. The ink and substrate are chosen such that the polarity (ϒRho/ϒD)1/2 of the substrate surface is less than or equal to 0.6 and the difference in polarity of the substrate surface and the ink [Delta(Polarity)] is less than or equal to 0.1. The result is higher resolution in the printed pattern such as higher resolution in printed lines.
