Abstract: The invention relates to a device for decorating containers having a plate cylinder with a full-area or partial-area printing plate, or a printing plate with a partial raster, and a blanket cylinder which carries a plurality of rubber blankets so as to follow one another in the circumferential direction thereof. The blanket cylinder is arranged with respect to the plate cylinder in such a way that the rubber blankets are in rolling engagement with the plate cylinder. The rubber blankets are provided with raster images which are formed by elevated raster dots of various diameter and depressed regions which lie in between. The raster dots are arranged along a regular raster. During operation, the raster dots take up ink from the surface region of the printing plate and deposit it in turn onto a container to be decorated. According to the invention, the rasters, in which the raster dots of the raster images are arranged on rubber blankets which follow one another, are offset relative to one another by a raster angle which is greater than 0°.

Abstract: Apparatus for decorating a can body. The apparatus comprises a can body conveying mechanism (1) for conveying can bodies (2) to a printing zone (3), a blanket wheel (4) comprising a plurality of blanket segments (6) and, affixed to each blanket segment, a blanket (7) having a printing surface, the blanket wheel being configured to bring blanket printing surfaces into contact with can bodies within said printing zone, and a plurality of ink stations (5) each comprising a printing plate (31) configured to contact the printing surfaces of passing blankets in order to impart an ink image to the printing surfaces, such that a composite ink image is formed on each blanket printing surface and is printed onto a can body upon contact of the blanket printing surface and the can body within the printing zone. The apparatus is configured such that at least one of the blankets has a surface height variation across its printing surface representing a secondary image to be transferred to can bodies with which the blanket comes into contact. A drive mechanism (32) is provided for causing the printing plates to rotate and a drive mechanism controller for varying the rotational speed of the printing plates to synchronise the positions of the printing plates with blankets onto which ink images are to be transferred.

Abstract: The present invention relates to a process for the preparation of thin silver nano-particle layers, which are produced directly on a substrate as part of a coating or printing process. The layers show different colours in transmittance and reflectance. The layers do not show the typical conductivity of metallic layers, since the particles are essentially discrete particles which are not sintered. The invention further relates to decorative and security elements. When the layers are applied over a security element, such as a hologram, the obtained products show also different colours in reflection and transmission, an extremely bright optically variable image (OVD image) and high purity and contrast. Depending on the thickness of the layer a more or less intensive metallic aspect appears.

Abstract: This disclosure is directed to a plate design for use in variable data digital lithographic image forming devices. The disclosed plate design incorporates surface passivated carbon black filler material particles in a fluorosilicone polymer. The disclosed functionalized carbon black material compositions include hydrophobic carbon black particles surface passivated via the use of an A/B-block copolymer where the A/B block contains a pentafluorostyrene-maleimide alternating polymer and the B block contains pure pentafluorostyrene. The A/B portion allows for the polymer to adsorb onto the carbon black while the b-block acts as the stabilizer in fluorinated systems. Fine dispersions result from the addition of poly (pentafluorostyrene/Maleimide-b-pentafluorostyrene) or P(PFS/MI-b-PFS) passivated carbon black to fluorinated polymers, enhancing the physical and mechanical properties. The disclosed surface passivated carbon black particles are particularly usable for improving operational characteristics of fluorosilicone-based reimageable surface layers of imaging members employed in the variable data digital lithographic image forming devices.
