摘要:
The invention disclosed herein relates to apparatus, systems and associated methods for supplying ink to printing presses. The ink supply systems operate in combination with a printing system and comprise a bulk ink supply system and a supplemental ink supply system. The bulk ink supply system and supplemental ink supply system can jointly, or individually, supply inks of different colors to individual press units of a printing press. The bulk ink supply system includes one or more supply lines leading to the printing press for supplying ink to the printing press in bulk. The supplemental ink supply system includes one or more ink canisters for supplying ink to the printing press. An intermediate ink supply system may be operated in addition to and/or in place of the bulk and/or supplemental ink supply system.

A rotary, non-wetting rotary printing apparatus, particularly of the flexographic type, adapted for printing on a web of material (1) in several colours or screens is described. The apparatus is characterized in that the blanket cylinder (3), the surface of which is free from any wetting liquid, is tangential to at least two printing forms (4, 5) which are in turn tangential to respective inking cylinders (6, 7), so that different inked areas of the same colour but from different screens, or of different colours, are depositied on the peripheral surface of the common blanket cylinder (3), to be transferred by the latter onto the web of material (1).

A cylinder (14, 16) is described for a printing machine of the type comprising at least one first printing cylinder (14), placed in contact with at least one opposing cylinder (20), at least one second printing cylinder (16), placed in contact with the first printing cylinder (14), and a plurality of ink rollers (10), placed in contact with the first printing cylinder (14). The cylinder (14, 16) is provided, at least one of its lateral ends, with one or more rigid abutment rings (26), each of such rigid abutment rings (26) being mounted on the cylinder (14, 16) by means of the interposition of one or more rolling bearings (28) which allow the rigid abutment rings (26) to remain stopped, or to rotate with different speeds, during the rotation of the cylinder (14, 16) around its own axis (A).
摘要:
The present invention provides articles comprising a substrate, a coating that is applied to the substrate, and surface reliefs that are cast or embossed onto the coating at substantially the same speeds and widths of conventional printing, and in substantially perfect register to conventional printing, wherein the coating is selected from the group consisting of HRISR coatings, LRISR coatings, water-based coatings, solvent-based coatings, UV/EB based coatings, sol-gel based coatings, conductive coatings, silver reduction based coatings and metallic coatings, A protective or printed layer may (or may not) be applied on top of the coating. Specifically, if the coating is an HRISR or LRISR coating, then it is unnecessary to apply a special high refractive layer because HRISR and LRISR coatings inherently contain the refractive index properties that are necessary to keep the surface reliefs viewable despite any printing on top of the coating. Otherwise, if the coating does not comprise an HRISR or LRISR coating, then a high refractive protective layer is applied on top of the coating, wherein the protective layer follows a topography of the surface reliefs such that a thickness of the protective coating is substantially uniform.

Die Erfindung betrifft eine Vorrichtung zum Bedrucken von Hohlkörpern, wobei diese Vorrichtung mehrere Druckwerke jeweils mit einem Druckformzylinder (04) aufweist, wobei mindestens eines dieser Druckwerke ein Farbwerk (06) mit einem Druckfarbe bereitstellenden Kammerrakelsystem (09) aufweist, wobei das betreffende Kammerrakelsystem (09) in einer einzigen Baueinheit zumindest eine Farbwanne und einen Rakelbalken aufweist, wobei diese Baueinheit des Kammerrakelsystems (09) im Farbwerk (06) nur einseitig gehalten ist, wobei die Baueinheit des Kammerrakelsystems (09) einen Kragarm an einem Seitengestell des Farbwerks (06) bildet, wobei die Baueinheit des Kammerrakelsystems (09) achsparallel zur Rasterwalze (08) bewegbar und durch diese Bewegung aus dem Farbwerk (06) entfernbar ist.
摘要:
In order to print identification marks (200, 200') in the exact target position on a value or security document (100), the invention relates to a printing forme device (700) for applying identification marks (200, 200') to a printing stock (105). Said device (700) comprises at least one numbering unit (800) which is arranged on a rotatable holding element (710) and the position of which on the rotatable holding element (710) is adjustable. According to the invention, (a) at least one identification mark (200, 200') is printed onto the printing stock (105); (b) the position of the at least one identification mark (200, 200') on the printing stock (105) is ascertained; (c) the ascertained position of the at least one identification mark (200, 200') is compared with a target position; and (d) the position of the at least one numbering unit (800) on the rotatable holding element (710) is adjusted.

The present invention provides articles comprising a substrate (80), a high (or low) refractive index and/or metallic surface relief coating (84) that is applied to the substrate (80) and surface relief structures (86) that are applied to the coating (84) at substantially the same speeds and widths of conventional printing systems, and in substantially perfect register to conventional printing systems, thereby obviating the need for already-embossed substrates including films and hot-stamping foils.
