Abstract:
An ink jet printing medium for an embossed interior decorating member includes a base member having a face, a thermoplastic resin layer deposited on the face of the base member, and a non-aqueous and porous ink receiving layer, deposited on the thermoplastic resin layer, for receiving liquid pigment ink. The thermoplastic resin layer is made of a material including a thermoplastic resin and a heating foaming agent dispersed in the thermoplastic resin. In an aspect, the thermoplastic resin layer has not yet been foamed. In another aspect, the thermoplastic resin layer has already been foamed. In still another aspect, the thermoplastic resin layer has already been foamed and embossed.
Abstract:
Methods for reducing cavitation in impulse or drop on demand ink jetting devices are provided. Impulse ink jet compositions including antioxidant are also provided which are suitable for printing clear, well-defined alphanumeric text or low spread, narrow bar width bar codes on porous substrates such as Kraft paper or corrugated cardboard. The antioxidant additive lowers the dissolved oxygen level in the ink, thereby enhancing the jetting performance of the printhead.
Abstract:
An ink jet recording head includes a plurality of recording elements arranged in an array on a substrate, the recording elements having electric resistances with a variance not less than 4% from a resistance value of at least one of the recording elements, wherein the recording elements generate ink ejection energy to effect printing; a plurality of measuring elements, disposed adjacent at least each of the opposite ends of the array of the recording elements, for detesting characteristic values of the recording elements; and a storing section for storing an average, a median or a reference value corresponding thereto.
Abstract:
An ink jet printing method, including the steps of: A) providing an ink jet printer that is responsive to digital data signals; B) loading the printer with ink jet recording elements with a support having thereon an image-receiving layer of a polymer having a given contact angle; C) loading the printer with an ink jet ink composition; D) printing on the image-receiving layer using the ink jet ink in response to the digital data signals to form an imaged recording element; and E) heating the imaged recording element sufficiently to cause the layer of polymer to increase the contact angle at least about 15 degrees.
Abstract:
A vacuum holddown for a hard copy device comprises a platen having plural vacuum zones arranged in a side-by-side array across the platen. Each vacuum zone has a closed end and an open end and is coupled to a vacuum source. Each vacuum zone defines a recess in the upper surface of the platen that is fluidly coupled to the vacuum source through a port. The back walls and side walls of each vacuum zone are coplanar with the upper surface of the platen. A step may be positioned in the vacuum zones to define an open vacuum zone having multiple depths.
Abstract:
A method and apparatus for cleaning a perforated, transport belt has belt surface cleaner mechanisms that include a pair of moveable, consumable webs. A scrubbing of the belt by a wet web is followed by a scrubbing of the belt by a dry, absorbent web. A solvent dispensing mechanism can be fluidically coupled to re-soak the wet web. Mechanisms for selectively engaging and disengaging the belt surface cleaner mechanisms ensure free belt travel during flexible material transport and the cleaning of both surfaces during cleaning cycles. The system includes consumable piece-part elements for refurbishing and remanufacturing.
Abstract:
An ink for ink-jet recording of the present invention includes a dispersion of a pigment, and an ink solvent containing a water-soluble organic solvent and glycol ether. The ink is prepared such that an Rf value, which represents a rate of flow of the pigment obtained when the pigment dispersion is developed with the ink solvent by means of paper chromatography, is not more than 0.5. The ink has a fast permeation speed, and hence the feathering and the bleeding are avoided.
Abstract:
A recording method including the step of providing an ink from a recording head to a recording medium through a gap provided between the recording head and the recording medium, the ink being supplied to the recording head from an ink tank including an ink contact member and the ink contacting the ink contact member, wherein the ink includes: (i) a fluorescent coloring material; (ii) a nonionic surfactant; (iii) a compound which is not compatible with (ii); and (iv) a liquid medium for dissolving or dispersing (i), (ii) and (iii), and wherein the ink contact member comprises at least one compound selected from the group consisting of polyacetate and polyolefin.
Abstract:
Disclosed is a process which comprises (a) incorporating into an ink jet printing apparatus (1) a first ink comprising water and at least one anionic monomer; and (2) a second ink comprising water and at least one cationic monomer, wherein the anionic monomer and the cationic monomer are selected so that upon contact of the anionic monomer with the cationic monomer, spontaneous polymerization or copolymerization of at least one of the anionic monomer or the cationic monomer occurs, and wherein at least one of the first ink and the second ink further comprises a colorant; (b) causing droplets of the first ink to be ejected in an imagewise pattern onto the substrate; and (c) causing droplets of the second ink to be ejected in an imagewise pattern onto the substrate; wherein the process results in at least some portions of the substrate bearing images formed from both the first ink and the second ink, said portions forming a printed image containing the colorant and a polymer formed from at least one of the anionic monomer or the cationic monomer. Similar processes are disclosed with N,N-dimethylaminoethyl methacrylate and p-toluene sulfonic acid, with acrylamide and a multivalent metal nitrate salt, and with 5-vinyl tetrazole and an amine base.
Abstract:
An apparatus incorporating multiple electrical interconnects extending through a substrate (e.g., a silicon wafer), and a method of forming the same. The electrical interconnects convey electrical signals through the substrate to structures mounted on the front side of the substrate. A conductive layer can be used to selectively distribute the electrical signals to the structures. Accordingly, it is not necessary to route electrical signals to the front side of the substrate in order to convey the signals to the structures. A structure can be coupled to multiple electrical interconnects in order to convey electrical signals along redundant paths through the substrate to the structure, improving reliability should one of the electrical interconnects fail.
