Abstract:
An ink jet recording head has a plurality of discharge energy generating devices for discharging recording liquid, while being provided with a recording element base plate arranged on the face opposite to the surface where the devices are arranged, having a plurality of recording liquid supply ports for supplying recording liquid to the devices, as well as with a supporting member that holds and fixes the recording element base plate. For the supporting member, a plurality of recording liquid supply paths are arranged to supply recording liquid to each of the supply ports of the recording element base plate, respectively, and then, the flow path width of each supply flow path is formed to be smaller than the opening width of inlet portion of each supply port. Further, the steps to be created between the supply flow path and the supply port is buried by the bonding agent forced out from the bonding face of the recording element base plate and the supporting member. With the structure thus arranged, the ink jet recording head is capable of optimizing the discharge characteristics of recording liquid and the supply characteristics thereof, as well as the positioning precision of a recording element base plate to a supporting member.
Abstract:
A method for the image-wise transfer of fluid droplets from at least one fluid droplet source onto a substrate comprises ejecting fluid droplets from the at least one fluid droplet source onto a transfer surface. The fluid droplets may be water-based or oil based. The transfer surface repels the fluid droplets. For water-based fluid droplets, the transfer surface comprises a spatially periodic arrangement of less-strongly hydrophobic regions and more-strongly hydrophobic regions. The method includes adjusting a spatial registration of the fluid droplets on the transfer surface; and transferring the fluid droplets from the transfer surface to the substrate by bringing the fluid droplets on the transfer surface into contact with the substrate.
Abstract:
A heated media deflector for an inkjet printer. The media deflector is located in a transition area between a horizontal printing plane and a vertical feeding path. The media deflector includes a plastic support portion and a sheet metal portion with a heating resistor attached to a bottom surface of the sheet metal portion. The sheet metal portion provides a guiding surface for guiding a media from a printing zone to the vertical feeding path. The sheet metal portion of the heated media deflector also radiates heat that dries excess water absorbed by the media during printing. The inkjet printer includes a controller for controlling the heating temperature of the heated media deflector. The heating temperature is set based on environmental conditions and print job parameters.
Abstract:
There is provided an image-forming method which is capable of carrying out edge-to-edge properly on a medium such as a card, and a print medium and a sheet cartridge for use in the image-forming method. An image is printed on an ink image-receiving sheet by using a sublimable dye ink, thereby causing the sublimable dye ink to be held by the ink image-receiving sheet. The image is fixed on the medium body by heating the ink image-receiving sheet and a medium body overlaid to each other and thereby causing diffusion of the sublimable dye ink held in the ink image-receiving sheet on a surface of the medium body for color development. Then, the ink image-receiving sheet is removed from the medium body having the image fixed thereon. In this image-forming method, the ink image-receiving sheet is formed to have a larger size than the medium body.
Abstract:
A dummy image is formed on a periphery of a retransfer image region on a transfer medium where a primary transfer image is not retransferred on the transfer medium when the primary transfer image is formed on the intermediate transfer film. As the result, peeling tension exerted on the intermediate transfer film is approximately even in a width direction, the primary transfer image is retransferred onto the transfer medium without changing of a transfer condition, and an optimal retransfer condition can be obtained.
Abstract:
An aqueous recording liquid suitable for use in ink jet printing containing a colorant, 2,2,4-trimethyl-1,3-pentanediol, and at least one surfactant selected from polyoxyethylene alkyl ethers and polyoxyethylene alkyl ether acetates.
Abstract:
An ink jet recording apparatus comprises a recording area where a recording sheet is conveyed substantially in a horizontal direction to a position opposite to a discharge port for discharging ink, and recording is performed by discharging ink from the discharge port downwardly substantially in a vertical direction to the recording sheet and a sheet-exhausting area where the recording sheet is conveyed from the recording area and exhausted. The sheet-exhausting area has a first sheet conveyor for introducing the recording sheet from the recording area to the sheet-exhausting area and a second sheet conveyor for holding the recording sheet introduced from the recording area to the sheet-exhausting area by the first sheet conveyor substantially in the horizontal direction or above the substantially horizontal direction and exhausting the recording sheet substantially in the horizontal direction or above the substantially horizontal direction.
Abstract:
A printhead cartridge mounts within a carriage of a printer. The carriage moves along a first direction within the printer. The printhead cartridge includes an inkwell for storing ink, which has a front surface and a bottom surface, a printhead mounted on the bottom surface, and a plurality of contacts for receiving signals from the printer and to provide the signals to the printhead. A centerline of the front surface, running perpendicular to the first direction, evenly defines first and second sides of the front surface. The contacts are disposed on the front surface, and a distribution of the contacts on the first side exceeds a corresponding distribution of the contacts on the second side.
Abstract:
An ink-jet printable static cling film including a support, a vinyl film, a curl avoiding polymer layer and a dye-receiving layer, said curl-avoiding polymer layer provides a stiffness (100% modulus) according to ASTM D412-98a of from about 9 to about 34 MPa and a percent (%) elongation according to ASTM D2370-82 of about 250 to 400%.
Abstract:
The present invention includes an embodiment for optimizing the temperature operating range for a thermal inkjet printhead using ink over large print swaths. In general, this embodiment includes receiving the temperature of a digital temperature sensor (DTS) before printing begins, comparing this temperature with the set point for printing, initiating heating elements if the temperature is below the printing threshold, and turning off those heating elements when the threshold temperature of the die has been reached. The method and process minimizes thermal excursions, either above or below the set point for the production of ink droplets, and maintains an approximate isothermal environment for operation.
