Abstract: Method and apparatus for transferring a developed image from an image bearing member to a receiver substrate in a Contact Electrostatic Printing (CEP) system may be provided according to the present invention. The developed image is formed of a development material having a mixture of carrier fluid and pigmented polymeric particles, the composition of such mixture being selected for its characteristic behavior at an elevated temperature for transitioning to a substantially single phase. The method includes the steps of developing an image onto an image bearer using the aforementioned development material; concentrating the developed image; heating the developed image to a temperature at which the polymeric particles and the carrier fluid achieve a substantially single phase condition, so as to form a transferable image; and transferring the transferable image to a receiver substrate such as a paper sheet.

Abstract: A method and system for converting, transforming or translating an imaging element associated with a first resolution into a second imaging element associated with a second resolution are provided. The method and system provide for the selection of output imaging element pattern based on context information extracted from areas neighboring an area undergoing conversion when information extracted from the area undergoing conversion provides an insufficient basis from which to select an output imaging element pattern. Exemplary embodiments are directed toward preservation of area coverage and centroid placement. The method provides for consideration of characteristics of a marking engine in the output imagine element pattern selections process. In xerographic environments clustering can be maximized, thereby reducing xerographic stress. In inkjet environments output pattern selections can be directed toward decreased clustering.

Abstract: When ejectors (nozzles) are viewed in order in a sub-scanning direction, the ejectors are arranged so that positions of the ejectors in a main scanning direction alternate in an offsetting manner. When formed dots are viewed along the sub-scanning direction, sizes of the dots are changed at random. Accordingly, density unevenness is decreased, the ejectors can be arranged in high density, and an image can be recorded at high speed. That is, the invention provides a droplet ejecting head in which density unevenness which tends to be generated in a head having a matrix-like nozzle arrangement can be decreased without decreasing recording speed and thus high-speed recording is made compatible with high-quality recording. The invention also provides a droplet ejecting apparatus which is provided with the droplet ejecting head.

Abstract: An information processing apparatus acquires both model information of a first device and identification information specific to the first device from the first device, and acquires configuration information of the first device. Then, the information processing apparatus stores the acquired configuration information in a status correlated with the model information and the identification information. On the other hand, in such a case that both the model information and the identification information are transmitted from a second device, the information processing apparatus determines whether the stored model information is made coincident with the transmitted model information. When the transmitted model information is made coincident with the stored model information, the information processing apparatus transmits the stored configuration information to the second device. The second device receives the configuration information and configures in accordance with the transmitted configuration information.

Abstract: A compression and decompression system and process for optimally compressing and decompressing multibit per pixel image regions based on the type of data contained in the image region, e.g., whether the image region contains continuous tone data, including data to be halftoned, or non-continuous tone data, including antialiased text and lineart data. Segmented bytemap data blocks are processed to provide both low spatial resolution continuous tone data and high spatial resolution non-continuous tone data. However, the high spatial resolution non-continuous tone data is generated by quantizing and packing the high resolution bytes across an edge and discarding the high resolution bytes along the edge, i.e., the multibit data is discarded only in directions parallel to the edges of marks to be rendered in the image data. Additional information indicating the directions of the edges in the image data are stored to aid in decompression.
