An apparatus for providing a printed and textured web substrate is disclosed. The apparatus has a printing apparatus and an apparatus for imparting elastic-like behavior. The printing apparatus has at least one rotatable ink roller for transferring an ink to the web substrate. The apparatus for imparting elastic-like behavior has a pair of intermeshing rollers capable of providing at least a portion of the web substrate with an elastic-like behavior.

The invention relates to a web-fed rotary printing press having a plurality of double printing units in which each of the printing units of the double printing units work together in the blanket-blanket method and each has its own drive. Transfer cylinders of each printing unit are driven independently. To permit a rapid change in production, both upon recto and verso printing, the transfer cylinders of the disconnectable double printing units are separable by eccentric bushings or swingable levers such that a web which passes through the printing press is conducted between them without being printed.

The present invention relates to a method for producing a photovoltaic novelty item. Conductive polymer solutions and semiconductive oxide dispersions are formulated into inks that are laid down on top of one another to produce voltage and current when exposed to light. In addition, these inks may be printed on novelty items, such as magazine advertisements or greeting cards, connecting to printed light emitting graphics.

Provided are an electrode for a secondary battery employing an active material layer having improved thickness uniformity by printing low-viscosity ink on the active material layer, a manufacturing method of the electrode, and a secondary battery having improved electrode capacity due to the employing of the electrode. The electrode includes a current collector, and an active material layer formed by printing ink having a viscosity not exceeding 500 mPa·s on the current collector and drying the current collector, wherein the current collector has a surface roughness (Ra) in a range from about 0.025 to 1.0 μm.

The invention relates to a device for printing by transfer onto a print support (10) comprising at least one blanket (30) driven in a sequential relative movement past a magazine (50) conveying the print supports (10), in which device the blanket (30) has a surface area greater than that of the print support (10), the device further comprising digital printing means (20) which print by spraying ink onto this blanket (30) over a variable area equal to that of the print support (10).

Large throw-off distances of the transfer cylinders in a double printing unit of a rotary printing machine operating on the rubber/rubber principle are achieved by enabling the two transfer cylinders to be set away from each other, and enabling the two form cylinders to be set away from the respective transfer cylinder. The form cylinder and the transfer cylinder of each printing unit have a drive connection via spur gears, the transfer cylinders are not in tooth engagement via their spur gears, and each printing unit has its own electric motor.

A process including: forming a first mixture of a first fluoroelastomer, and a first polymeric siloxane containing free radical reactive functional groups; and forming a second mixture of the resulting product with a mixture of a second fluoroelastomer and a second polysiloxane compound, and wherein the resulting product of the dissimilar polymeric materials is a phase compatible blend. The phase compatible blend is useful as a component of electrostatographic and liquid ink printing machines, including long-life fuser rolls, backing rolls, transfer and transfuse belts and rolls and bias charging and bias transfer rolls.

A two stage printing process that includes a digital first stage in the form of a non-contact material metering device, such as one or more digital inkjet heads, for selectively discharging a metered quantity of material, and an analog second stage, such as flexographic print and impression cylinders, for transferring the material deposited thereon by the non-contact material metering device onto a substrate.

A method for delivering a High Internal Phase Emulsion to a substrate. The method includes providing a rotating roll, The rotating roll has a central longitudinal axis, wherein the rotating roll rotates about the central longitudinal axis, an exterior surface defining an interior region and substantially surrounding the central longitudinal axis, and a vascular network configured for transporting the one or more fluids in a predetermined path from the interior region to the exterior surface of the rotating roll. The method further includes providing a High Internal Phase Emulsion to the rotating roll vascular network. The method further includes contacting a substrate with the rotating roll and contacting the substrate with the High Internal Phase Emulsion.

Systems and methods for high-speed variable printing are provided. Ink jet technology and lithographic systems may be combined in such a way to create a fully variable and high-quality print system. An aqueous solution is applied to a cylinder to produce a first negative image. A positive image in ink is transferred to a print medium. Residue ink and aqueous solution is then cleaned from the cylinder and aqueous solution is applied to the cylinder to produce a second negative image. The systems and methods described herein may be used to create high-quality one-to-one marketing applications.

A pattern transfer apparatus is constituted by a first mold holding portion for holding a first mold for forming a pattern inside a peripheral area of a member and a second mold holding portion for holding a second mold for forming a pattern in the peripheral area of the member.

A method for producing a lithographic printing plate is provided, wherein, in the non-alkaline development of a lithographic printing plate precursor having a protective layer, even if the protective layer components are mingled into the developer, the reduction in development removability of the image recording layer and the generation of development scum can be inhibited; an on-press development type lithographic printing plate precursor with excellent inking property, high scratch resistance, satisfied on-press developability and good fine line reproducibility is provided; and a lithographic printing method is provided, each of which is a method for producing a lithographic printing plate, comprising: imagewise exposing a lithographic printing plate precursor comprising a support, an image recording layer and a protective layer, and rubbing the plate surface by a rubbing member of an automatic processor in the presence of a developer at a pH of 2 to 10 to remove the protective layer and the image recording layer in the unexposed area; a lithographic printing plate precursor comprising a support, an image recording layer removable with a printing ink and/or a fountain solution, and a protective layer containing a polyvinyl alcohol having a carboxyl group and/or a sulfonic acid group within the molecule; and a lithographic printing method comprising on-press development.
