Described herein are an apparatus and a method for direct engraving an elastomeric printing plate by multiple laser beams simultaneously. In one embodiment, an elastomeric printing plate or sleeve is positioned on an imaging drum for direct engraving. The imaging drum is rotatable around its longitudinal axis. Such rotation defines a circumferential direction, also called the transverse direction. The axis of rotation defines an axial direction, also called the longitudinal direction. The printing plate has an body and a surface made of an elastomer (made of polymer or rubber). A drive mechanism provides relative motion between a plurality of laser beams and the plate in both the transverse and longitudinal directions.

A high-quality electrophotographic endless belt and a method capable of efficiently producing the belt are provided. A method for producing an electrophotographic endless belt comprising a base layer including a thermoplastic resin composition and an inner-surface layer, which includes: (1) forming an energy curable film having a glass transition temperature on an inner surface of a test tube-shaped preform including a thermoplastic resin and then subjecting the preform to blow molding to obtain a blow-molded bottle; (2) irradiating the blow-molded bottle with energy rays to cure the film to form an inner-surface layer; and (3) cutting out an endless belt from the blow-molded bottle having the inner-surface layer obtained in (2).

A three-dimensional printing head includes a housing (100), a fusing module (200) arranged in the housing (100), and a heat dissipation module (300). The fusing module (200) is disposed in the housing (100) and includes a feeding tube (210) with both ends open. A feeding inlet (211) for receiving a filament material (20) is at one end of the feeding tube (210), a supplying nozzle (220) is at the other end of the feeding tube (210), and multiple fins (212) are formed outside of the feeding tube (210). A heater (230) is disposed at the supplying nozzle (220) to heat the same for melting the filament material (20). The heat dissipation module (300) includes a fan (310) arranged in the housing (100), and the fan (310) has an inlet side (311) and an outlet side (312) opposite thereto. The outlet side (312) is arranged toward the fusing module (200).

In one example, a process for making a micro device structure includes molding a micro device in a monolithic body of material and forming a fluid flow passage in the body through which fluid can pass directly to the micro device.

A curved fluid ejection device may include a plurality of fluid ejection dies overmolded with at least one layer of epoxy mold compound (EMC). Each of the fluid ejection dies and the EMC include a coefficient of thermal expansion (CTE). The combination of the CTE of the fluid ejection dies and the CTE of the at least one layer of EMC defines a curve within the curved fluid ejection device.

A toner supply roller (1) is produced by preparing a rubber composition which contains a rubber component including an epichlorohydrin rubber and a butadiene rubber, a crosslinking component and a foaming component and, while extruding the rubber composition into a tubular body, continuously foaming and crosslinking the rubber composition of the tubular body by a continuous crosslinking apparatus including a microwave crosslinking device and a hot air crosslinking device. An image forming apparatus incorporates the toner supply roller (1).

The invention relates to a method (100) for producing an image structure (12) according to an image specification (20), in particular for a letterpress process and/or intaglio printing process, characterized in that the following steps are carried out: a) providing a base (10) for receiving the image structure (12), b) producing an image structure (12) on the base (10) so that an image layer (11) is formed on the base (10) by means of the image structure (12).

There is provided a method for manufacturing a molded member having a hollow part. The method comprises a step for molding the hollow part by extracting a first piece, a second piece, a third piece and a fourth piece of a mold in four different directions. The second piece has an elongated shape in its extracting direction, the second piece and the fourth piece have extracting directions substantially opposed to each other, and at the molding, each of the first piece, the second piece, the third piece and the fourth piece abuts on at least one of the first piece, the second piece, the third piece and the fourth piece.

Microporous structures in face films are described for improving printability of the films. Also described are laminates and pressure sensitive adhesive laminates including the microporous structured face films. Various related methods are additionally described.

A method of producing a granulated product from photopolymer printing plate materials. The method includes the steps of (a) sorting the photopolymer printing plate materials based on an identifiable property, wherein the photopolymer printing plate materials comprise one or more photopolymer layers; (b) grinding the photopolymer printing plate materials to particles; and (c) screening the particles to remove particles above a certain size and create the granulated product.
