A method for applying an electrical conductor to an electrically insulating substrate, the method comprising providing a flexible membrane with a pattern of grooves formed on a first surface thereof, and loading the grooves with a composition comprising particles of a conductive material. The composition is, or may be made, electrically conductive. Once the membrane is loaded, the grooved first surface of the membrane is brought into contact with a front or/and back surface of the substrate. A pressure is then applied between the substrate and the membrane(s) so that the composition loaded into the grooves adheres to the substrate. The membrane(s) may remain on the electrically insulating substrate. The electrically conductive particles in the composition can then be sintered to form a pattern of electrical conductors on the substrate, the pattern corresponding to the pattern formed in the membrane(s).

Application of electrical conductors to an electrically insulating substrate

An apparatus is disclosed for printing images on generally cylindrical objects. The apparatus comprises an impression station that includes a movable imaging surface for bearing an ink image; and a transport mechanism for advancing the objects through the impression station, comprising a drive member rotatably connected to a plurality of rotatable mandrels, each for mounting a respective one of the objects, the transport mechanism being configured to cause each object to rotate during passage through the impression station such that, within a nip region of the impression station, the surface of the object makes rolling contact with the imaging surface, thereby causing the ink image to be impressed on the object. An impression platen is provided opposite the imaging surface within the nip region, the impression platen being configured to apply a force, directly or indirectly, to the objects to ensure rolling contact between the objects and the imaging surface.

Apparatus for printing on cylindrical objects having device to prevent loading of objects onto mandrels

A printing assembly for thermal transfer printing is disclosed. The assembly comprises at least one first printing system comprising a transfer member having an imaging surface on the front side, a coating station at which a monolayer of thermoplastic particles is applied to the imaging surface, an imaging station at which electromagnetic radiation (EM) is applied, optionally via the rear side of the transfer member, to selected regions of the imaging surface to render the particles coating the selected regions tacky, a transfer station at which only the regions of the particles coating that have been rendered tacky are transferred to a substrate to form an adhesive image; and at least one more downstream printing system. The transfer member includes on its front side an EM radiation absorbing layer, the imaging surface being formed on, or as part of, the absorbing layer, and on its rear side a body which can optionally be transparent to EM radiation.

Thermal transfer printing

Embodiments of the invention relate to a method of indirect printing with an aqueous ink. Related apparatus, systems and treatment formulations are disclosed herein. Some embodiments relate to an aqueous treatment formulation for use with an intermediate transfer member of a printing system. In some embodiments, the system comprises a treatment station disposed downstream of the impression station and upstream of the image forming station for forming a uniform thin layer of a liquid treatment formulation onto a surface of an intermediate transfer member (ITM) at a lower run thereof.

Digital printing process

There is disclosed a method of manufacturing a multi-layered article including a finished outer surface optionally having particular surface properties. The article can be a self-supported strip having a smooth outer surface. The method is, for example, suitable for the preparation of multi-layered articles such as a flexible intermediate transfer member (ITM) for use in an indirect printing system. Uses of such articles are also disclosed.

Method of manufacturing a multi-layer article

A printing process is disclosed which comprises directing droplets of an ink onto an intermediate transfer member to form an ink image, the ink including an organic polymeric resin and a coloring agent in an aqueous carrier, and the transfer member having a hydrophobic outer surface so that each ink droplet in the ink image spreads on impinging upon the intermediate transfer member to form an ink film. The ink is dried while the ink image is being transported by the intermediate transfer member by evaporating the aqueous carrier from the ink image to leave a residue film of resin and coloring agent. The residue film is then transferred to a substrate. The chemical compositions of the ink and of the surface of the intermediate transfer member are selected such that attractive intermolecular forces between molecules in the outer skin of each droplet and on the surface of the intermediate transfer member counteract the tendency of the ink film produced by each droplet to bead under the action of the surface tension of the aqueous carrier, without causing each droplet to spread by wetting the surface of the intermediate transfer member.

A system is disclosed for transferring a substance pattern to a substrate. The system comprises a web carrying the substance pattern, a web drive mechanism for driving the web through a nip between a roller and an opposing surface, and a transport mechanism for advancing a substrate having parallel side edges towards the nip, for the substrate to be gripped in the nip and frictionally driven through the nip at the same time as, and with the same speed as, the web, the web being pressed against a surface of the substrate during passage through the nip to cause the substance pattern to transfer from the web to the substrate. The lateral abutments located on opposite sides of the substrate are movable towards and away one another and resiliently biased to grip it, the abutments serving to align the substrate with the web and to advance it towards the nip.

System for introducing a substrate into a nip

A jacket-securing arrangement is disclosed for mounting in a cylinder, which cylinder () has an outer surface and at least one recess () in the outer surface for receiving an inwardly turned edge of a replaceable jacket () overlying at least part of the outer surface of the cylinder. The jacket-securing arrangement is mountable within the recess so as not to project beyond the outer surface of the cylinder when the jacket is secured thereto, and includes a clamping lever pivotable about a shaft located within the recess between a clamping position in which the edge of the replaceable jacket is clamped between the lever and a side wall of the recess and a release position in which the lever is spaced from the side wall of the recess. A magnet is provided to retain the lever in the clamping position. The clamping lever is formed of two or more members assembled around the shaft and defining between them a bearing surface engaging an outer surface of the shaft. The shaft may be a gripper shaft including a plurality of grippers for securing a printing substrate sheet to the outer surface of a substrate transport cylinder of a printing system, the jacket-securing arrangement being disposed between grippers.

Arrangements for securing cylinder jackets

There is disclosed a condensation curable coating composition in the form of an oil-in-oil emulsion, the coating composition being able to protect surfaces coated therewith from undesired contamination by materials coming in contact therewith. The surfaces to be so protected by the coating composition, once cured, can, by way of illustration, be of parts of printing systems and the materials coming in contact with such surfaces can be ink images or residues thereof.

Compositions and protective coatings made therefrom
