Abstract:
An electrophotographic printing apparatus includes an image-forming member having a surface on which a latent electrostatic image can be formed and a developer for depositing a layer of ink onto the surface of the image-forming member. The ink includes charged ink particles and a carrier medium. A supply conduit is connectable to an ink tank for supplying ink to the developer. An exit conduit is connectable to the ink tank for delivering unused ink from the developer to the ink tank. The supply conduit, the developer and the exit conduit define a flow path. A separator is operable to separate the carrier medium from the ink particles. The separator is connectable to the flow path to receive unused ink and to reintroduce carrier medium extracted from the unused ink to the flow path.

Abstract:
An embossing apparatus includes an embossing die that includes a printed relief pattern made up of multiple layers of a deposited material. A resilient surface presses media against the embossing die such that embossed features corresponding to the embossing die are formed in the media. A method for embossing media includes forming an embossing die by depositing multiple layers of ink on a impression layer to form a relief pattern and pressing media against the embossing die to transfer the relief image to the media.
Abstract:
In one example, a web press includes a web press station and a convertible buffer near the web press station, the convertible buffer being configured to convert to a platform for accessing the web press station. A method for performing web press maintenance is also disclosed.
Abstract:
Coating apparatus including a spray to provide a coating, a controller to control the spray to vary a spraying width of the spray, and a first roller to receive the coating and to smear the coating on a substrate.
Abstract:
An embossing apparatus comprises an embossing die comprising a printed relief pattern, and a resilient surface for pressing media against the embossing die to emboss features corresponding to the printed relief pattern on the media, in which the printed relief pattern comprises a number of layers of a deposited material, and in which a number of layers of the deposited material closest to the top of the printed relief pattern comprises a deposited material with a relatively lower coefficient of adhesion than layers of the deposited material disposed under the deposited material closest to the top of the printed relief pattern. A printed relief pattern for embossing media comprises a number of preliminary layers, the preliminary layers comprising a first material, and a number of terminal layers, the terminal layers comprising a second material, in which the second material has a lower adhesive coefficient than the first material.
Abstract:
A printing device (100,101) has a first print engine (103, 303, 603, 703), a second print engine (105, 305, 605, 705), and a buffer device (107, 307, 609, 709, 711) disposed between the first (103, 303, 603, 703) and second print engines (105, 305, 605, 705). The buffer (107, 307, 609, 709, 711) is configured to store a variable amount of web substrate (106, 301, 713) received from the first print engine (103, 303, 603, 703) and feed the substrate (106, 301, 713) to the second print engine (105, 305, 605, 705).
