Abstract: Printing of information with a distinct tactile feel can be accomplished by electrographic techniques. Such electrographic printing includes electrographic printing of raised images to selected areas of a receiver member using electrographic techniques so that they are fixed according to the properties of the raised print such as according to the mass per unit area or toner height. In one embodiment, by slowing down the process speed of the fuser to allow for a longer dwell so that the large toner particles and/or toner mass needed to make raised image will properly adhere to the print media without artifacts. To keep the energy requirements and the cost of the equipment down a speed switching technique is used that slows the process speed of the fuser so that the raised image is properly fused on a wide range of paper types.

Abstract: The present invention provides a double-sleeved roller for use in an electrostatographic machine. The double-sleeved member includes a cylindrical rigid core member. A removable inner sleeve member (ISM) is provided that includes a compliant layer that surrounds and intimately contacts the rigid core member. A removable electrically conductive outer sleeve member (OSM) such that the OSM surrounds and intimately contacts said ISM wherein the ISM and OSM are removable or mountable simultaneously.

Abstract: Electrographic printing of one or more optical elements having a particular profile by electrographic techniques. Such electrographic printing comprises the steps of forming a desired print image, electrographically, on a receiver member utilizing predetermined sized marking particles; and, where desired, forming one or more final optical elements utilizing marking particles of a predetermined size or size distribution.

Abstract: In an apparatus for printing images on a moving primary imaging member by jetting ink, containing a fluid and marking particles, in an image-wise fashion onto the primary imaging member, a device for concentrating the ink prior to transferring a marking particle image to a receiver member. The ink concentrating device includes a fractionating unit for separating fluid of the ink from the marking particles. The fractionating unit is located a predetermined spaced distance from the primary image bearing member. An electrostatic field is established between the primary image bearing member and the fractionating unit for concentrating the marking particles in the liquid of the ink.

Abstract: A high speed digital printing apparatus having an imaging member, an ink jet head capable of image-wise jetting ink onto the imaging member, a mechanism for fractionating such image-wise ink on the imaging member to remove liquid therefrom, an intermediate transfer member onto which such image-wise ink is transferred from the imaging member, and a transfer member forming a nip with the intermediate transfer member for transferring a liquid-depleted image-wise ink to a receiver. An ink suitable for use in the printing press apparatus is formed by dispersing an ink concentrate with a suitable solvent.

Abstract: Printing of information with a distinct tactile feel can be accomplished by electrographic techniques. Such electrographic printing includes the steps of forming a desired print image, electrographically, on a receiver member utilizing standard size marking particles; and in areas of the formed print image, forming raised information by printing at least a first raised image and a second raised image. The print and raised images are fixing on the receiver member. The raised images are applied using toner particles having diameters substantially larger than the diameters standard size toner particles used for applying the print image.

Abstract: The present invention provides an article of manufacture using an electrophotographic printer to produce printed electronic circuits by printing a second conductive powder layer and a first thermoplastic layer in registration. The second conductive powder layer is permanently fixed to the first layer before removing conductive powder from portions of the substrate other than that coated with the thermoplastic patterned image.

Abstract: A printing method for producing a textured thin film image (142) upon a receiver (20(R)) is provided. The method may include the steps of a. depositing one or more toner images (50) to form a predetermined adhesive image (50) with more than one level of height; and b. applying and fixing a foil (30) to at least a portion of the adhesive image to create a textured thin film image (142).

Abstract: Electrographic printing of one or more toner layers having a particular pattern by electrographic techniques so that one layer acts as an adhesive, when fixed, for a thin film. Such electrographic printing comprises the steps of forming a desired print image, electrographically, on a receiver member utilizing marking particles; and applying the thin film in registration before activating the toner.
