Abstract

A method is disclosed for applying an electrical conductor to an electrically insulating substrate, which comprises providing a flexible membrane with a pattern of groove formed on a first surface thereof, and loading the grooves with a composition comprising conductive particles. 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 of the substrate. A pressure is then applied between the substrate and the membrane(s) so that the composition loaded to the grooves adheres to the substrate. The membrane(s) and the substrate are separated and the composition in the groove is left on the surface of the electrically insulating substrate. The electrically conductive particles in the composition are then sintered to form a pattern of electrical conductors on the substrate, the pattern corresponding to the pattern formed in the membrane(s).

Abstract

A printing apparatus and method are disclosed for printing on conical objects. An ink image is deposited onto the outer release surface of an intermediate transfer member (ITM) having the form of a flexible endless belt. After drying of the ink image on the ITM, the ITM transports the dried ink image to an impression station having a nip at which the ink image is transferred onto the objects. In order to permit printing on conical objects, the ITM is elastically deformable at least in the direction of movement of the ITM, and is guided in such a manner as to be elongated during passage through the impression station, the extent of elongation varying across the width of the ITM so as to match the surface velocity of the ITM to that of the object over the entire line of contact between the ITM and the object at the nip.

Abstract

A printing apparatus and method are disclosed for printing on three-dimensional objects. The apparatus employs an offset printing process in which an ink image is deposited onto an intermediate transfer member (ITM) having the form of a flexible endless belt. After drying of the ink image on the ITM, the ITM transports the dried ink image to an impression station having a nip at which the ITM is compressed between an object and an impression surface, so that the dried ink image is transferred from the ITM to the object. The impression surface may form part of a stationary anvil, the ITM sliding relative to the impression surface during passage through the impression station. To optimize throughput, the velocity of the ITM relative to the surface of the object at the impression station may be greater than the velocity of the ITM relative to the imaging station.

Abstract

A method and system for thermal transfer printing onto a printing substrate are disclosed, as well as a substrate printed therewith. A monolayer coating of thermoplastic particles is applied to at least a segment of an imaging surface of a moveable transfer member. Thermoplastic particles within one or more selected regions of the monolayer coating are heated to render such thermoplastic particles tacky. The imaging surface and a surface of the substrate are pressed against one another to cause the thermoplastic particles that have been rendered tacky to be transferred to the surface of the substrate, thereby forming thereon a receptive image. Embellishment particles are subsequently applied onto the surface of the substrate. The receptive image, or parts thereof, can be heated prior to, and/or during, application of the embellishment particles, in order to ensure tackiness of the receptive image and cause the embellishment particle to only adhere thereto.

Abstract

A method is disclosed for applying an electrical conductor to an electrically insulating substrate, which comprises providing a flexible membrane with a pattern of groove formed on a first surface thereof, and loading the grooves with a composition comprising conductive particles. 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 of the substrate. A pressure is then applied between the substrate and the membrane(s) so that the composition loaded to the grooves adheres to the substrate. The membrane(s) and the substrate are separated and the composition in the groove is left on the surface of the electrically insulating substrate. The electrically conductive particles in the composition are then sintered to form a pattern of electrical conductors on the substrate, the pattern corresponding to the pattern formed in the membrane(s).

Abstract

A printing apparatus and method are disclosed for printing on three-dimensional objects. The apparatus employs an offset printing process in which an ink image is deposited onto an intermediate transfer member (ITM) having the form of a flexible endless belt. After drying of the ink image on the ITM, the ITM transports the dried ink image to an impression station having a nip at which the ITM is compressed between an object and an impression surface, so that the dried ink image is transferred from the ITM to the object. The impression surface may form part of a stationary anvil, the ITM sliding relative to the impression surface during passage through the impression station. To optimize throughput, the velocity of the ITM relative to the surface of the object at the impression station may be greater than the velocity of the ITM relative to the imaging station.

A printing apparatus is disclosed for printing on an outer surface of three-dimensional objects. The apparatus employs an offset printing process in which an ink image is deposited onto the outer release surface of an intermediate transfer member (ITM) (30) having the form of a flexible endless belt. After drying of the ink image on the ITM (30), the ITM (30) transports the dried ink image to an impression station having a nip at which the ink image is transferred onto the surface of the objects. An object transport system (14) transports the 3D object to the impression station and rotates each object about its own longitudinal axis during passage through the impression station. To optimize throughput, the velocity of the ITM (30) relative to the surface of the object at the impression station is greater than the velocity of the ITM (30) relative to the imaging station (32).

IPC Classes  ?

• B41J 2/005 - Typewriters or selective printing mechanisms characterised by the printing or marking process for which they are designed characterised by bringing liquid or particles selectively into contact with a printing material
• B41J 3/407 - Typewriters or selective printing or marking mechanisms characterised by the purpose for which they are constructed for marking on special material
• B41J 2/01 - Ink jet

Abstract

There is disclosed a method of manufacturing a multi-layered article including a finished outer surface (122a) optionally having particular surface properties. The article can be a self-supported strip (122a,124a) having a smooth outer surface. The method is, for example, suitable for the preparation of a flexible intermediate transfer member (ITM) for use in an indirect printing system. Uses of such articles are also disclosed.

• B32B 37/00 - Methods or apparatus for laminating, e.g. by curing or by ultrasonic bonding
• B32B 27/28 - Layered products essentially comprising synthetic resin comprising copolymers of synthetic resins not wholly covered by any one of the following subgroups
• B41J 2/22 - Typewriters or selective printing mechanisms characterised by the printing or marking process for which they are designed characterised by selective application of impact or pressure on a printing material or impression- transfer material
• B32B 38/00 - Ancillary operations in connection with laminating processes
• B32B 37/24 - Methods or apparatus for laminating, e.g. by curing or by ultrasonic bonding characterised by the properties of the layers with at least one layer not being coherent before laminating, e.g. made up from granular material sprinkled onto a substrate
• B32B 37/26 - Methods or apparatus for laminating, e.g. by curing or by ultrasonic bonding characterised by the properties of the layers with at least one layer which influences the bonding during the laminating process, e.g. release layers or pressure equalising layers
