Abstract: An object optimized printed system includes an image output terminal controller. The system inputs a print file defining a plurality of pages in a page description language and locates the plurality of objects forming each page and their object types. Based on the determine object types and any explicit rendering commands in the PDL file, the system automatically generates rendering tags for each of the objects. The rendering tags are used to control the image output terminal to optimize the printing by the IOT on an object-by-object basis. Based on the objects and the generated rendering tags, the system generates the differing types of data and the command instructions on a scanline-by-scanline basis. The generated command instructions and data are output to the IOT controller scanline-by-scanline. The data output to the IOT controller includes metabit data which is generated from the rendering tags.

Abstract: Acoustically thin capping structures and acoustic droplet ejectors having fluid wells and which use such capping structures to create fluid cells. The inventive capping structures permit the accurate positioning of the free surface of a fluid, permit acoustically induced fluid droplet ejection, and prevent fluid from spilling from the fluid wells. "Acoustically thin" means that the thickness of the capping structure is small enough that the acoustic energy that is lost passing through the capping structure is less than 50% of the incident acoustic energy.

Abstract: In a printing system on-line sheet output system with a rotating disks type sheet inverter and stacker in which the printed sheets are individually registered and rotated for inversion before being released for stacking while partially held in slots in the disks, an integral on-line hole punching system is provided for selectively outputting those sheets with or without a preselected hole pattern. A plurality of laterally repositionable sheet punches are integrally rotatable with the sheet inverter disks and positioned to punch a sheet while that sheet is moving and being individually rotated for inversion by the disks, by engagement of the punches by sheet punch actuators, before that sheet is released for stacking. The sheet punches may be sequentially and/or profiled cam gradually activated as the sheet is rotated to reduce the maximum required sheet punching force.

Abstract: A block boundary information analyzing circuit extracts block boundary information from an input image signal. A blocking circuit divides the input image signal into block images while changing block boundary positions based on the block boundary information every time a coding operation is performed. A discrete cosine transform coder codes the respective block images. A block boundary information adding circuit adds boundary information to the coded image information.

Abstract: A method for varying a scanline rate of a digital scanner while maintaining a constant integration period. The scanner scans a scanline of an image, integrates an array of photosensors after a first predetermined period of time has elapsed and after a second predetermined period of time has elapsed. One of the predetermined periods is equal to an integration period of the array of photosensors, and the other period is equal to a difference between a time needed to process a scanline of image data and the integration period of the array of photosensors. The scanner produces a scanline of valid image data and a scanline of image data corresponding to the first scanned scanline. The scanner then scans the next scanline of the image.

C. about 95.degree. C. by a polytron shearing device operating at speeds of from about 100 to about 5,000 revolutions to yield stable pigmented submicron sized particles of from about 5 to about 150 nanometers; and thereafter separating said submicron particles and mixing said submicron particles with water.

Abstract: Several methods are provided for cleaning felt or foam materials that are used to store and deliver ink, particularly ink supplied to ink jet printheads in an ink jet printing system. The felt materials are contaminated during manufacture, by various antistats, primarily phosphates. These antistats later react with the ink to create kogation and nozzle blocking problems as well as reduction of surface tension of the ink. The methods of the invention are directed to reducing the antistats left in the storage material after manufacture. In one method, the material is washed in heated softened water. Prior to loading the material in the wash, IPA is added to the heated wash. The material is washed through two Wash/Rinse cycles and then dried. The removal of the calcium in the wash water via softening prevents the precipitation of calcium-phosphate salts, which, when the material later contacts the ink, reduces nozzle clogging caused by these precipitates.

Abstract: A circuit for enabling the raster display of text or line art in one constant color against a background of another constant color or against a continuous-tone picture, or the display of a continuous-tone picture through an arbitrary shape. The circuit has four channels, one each for constant colors, continuous-tone images, image masks, and instructions. The constant colors are stored in the first channel in the form of two 8-bit colors, one for the text or line art and one for the background. Any color pair can be read from this memory, divided into two 8-bit colors, and presented at two inputs of a final multiplexer. The second channel stores continuous tone color pictures and presents this information at a third input of the multiplexer. The third channel receives masks or outlines in the form of bitmaps and the fourth channel receives instructions which may be run-length encoded. These two channels combine their data, which is then used to control the multiplexer.
