An electrophoretic display comprising a fluid including a first species of particles and a charge control agent disposed between first and second electrodes. When a first addressing impulse have an electrical polarity is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse but having the same electrical polarity, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.

Colored electrophoretic displays using same polarity reversing address pulse

An adhesive composition comprising a polyurethane and a cationic polymeric dopant or a polymerizable cationic dopant may be used to form one or more adhesive layers of electro-optic assemblies. They enable improved electro-optic performance of the corresponding; electro-optic devices even at low temperatures.

Color electrophoretic displays using same polarity reversing address pulse

Improvements in the production of electro-optic displays include: (a) use of a masking film to keep a selected area of a backplane (such as a front electrode contact) free from electro-optic material; (b) spray coating of electrophoretic capsules on to a substrate under controlled conditions; (c) forming a monolayer of capsules on a substrate by prior deposition of a water-swellable polymer; and (d) overcoating a layer of electro-optic material with a solvent-free polymerizable liquid material, contacting this layer with a light-transmissive electrode layer, and polymerizing the liquid material to adhere the electrode layer to the electro-optic material.

Electro-optic displays, and processes for the production thereof

An electrophoretic medium comprises a fluid and at least one species of particles disposed, When a first addressing impulse is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.

Flexographic printing plates and other relief images can be formed from a laser-ablatable element having a laser-ablatable layer that is from about 300 to about 4,000 &#x3bc;m thickness. The laser-ablatable layer includes a film-forming material that is a laser-laser-ablatable material or the film-forming material has dispersed therein a laser-ablatable material. The laser-ablatable material is a polymeric material that when heated to 300&#xb0; C. at a rate of 10&#xb0; C./minute, loses at least 60% of its mass to form at least one predominant low molecular weight product. The laser-ablatable material also comprises at least 0.01 weight % of a depolymerization catalyst that is a Lewis acid or organometallic based catalyst. The element can be imaged by ablation at an energy of at least 1 J/cmto provide a relief image.

Ablatable elements for making flexographic printing plates

Flexographic printing plates and other relief images can be formed from a laser-ablatable element having a laser-ablatable layer that is at least 20 &#x3bc;m in thickness. The laser-ablatable layer includes a film-forming material that is a laser-laser-ablatable material or the film-forming material has dispersed therein a laser-ablatable material. The laser-ablatable material is a polymeric material that when heated to 300&#xb0; C. at a rate of 10&#xb0; C./minute, loses at least 60% of its mass to form at least one predominant low molecular weight product. The element can be imaged by ablation at an energy of at least 1 J/cm2 to provide a relief image.

An electrophotographic method for producing fused toner images on a receiver medium comprising the steps of: forming an electrostatic image pattern on an image forming member; developing the image pattern on the image forming member with fusible toner particles thereby forming a toner image thereon; transferring the toner image to the receiver medium; and heating the toner image to form a fused toner image on the receiver medium, wherein an amount of a plasticizer is added to the toner particles of the toner image after formation of the toner image on the image forming member and prior to or concurrent with fusing of the transferred toner image on the receiver medium, further wherein the amount of plasticizer added is effective in lowering the Tg of the toner below that of the toner under prevailing ambient conditions in the absence of the added plasticizer. The current invention overcomes the limitations of the prior art because the plasticizer is added immediately before fusing, thus avoiding toner clumping upon storage, as well as eliminating the high cost associated with a custom manufactured receiver that already contains plasticizer.

Method and apparatus for printing an image-wise ink pattern on a receiver. A primary imaging member includes a series of substantially equal-sized cells located over the substrate surface thereof. The primary imaging member has an electrically conductive layer. An ink jet printhead selectively ejects drops of ink into the primary imaging member cells in a desired image-wise ink pattern. The image-wise ink on the primary imaging member is fractionated to separate the liquid in the ink. A receiver is transported into operative association with the primary imaging member, and a transfer mechanism applies a pressure between the receiver and the primary imaging member, and establishes an electrostatic field to transfer the image-wise ink pattern to the receiver.

Method and apparatus for ink jet printing on patterned substrate

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.

Digital printing apparatus for producing prints at high speed

A camera that is adapted to present a preview image is provided. The camera has a trigger adapted to generate a trigger pulse and an image capture system for capturing images of a scene. A viewer is adapted to present one image to a first viewing area and another image to a second viewing area. A controller is adapted to receive a first trigger pulse and to cause the image capture system to capture a first image of the scene in response to the first trigger pulse. The controller is also adapted to receive a second trigger pulse and to cause the image capture system to capture a second image of the scene in response to the second trigger pulse and to cause the viewer to simultaneously present the first image to the first viewing area and to present the second image to the second viewing area. An observer positioned with a first eye in the first viewing area and a second eye in the second viewing area can detect parallax differences between the first image and the second image.
