摘要： Halftone generating methods and systems convert continuous tone anti-aliased image data to halftone image data using halftoning techniques that efficiently use memory resources. One of a plurality of Holladay counters is selected and the address bits from the selected Holladay counter are output to a look-up table that efficiently stores various halftone screens. Halftone image data is then output. If necessary, the halftone image data is unpacked and replicated as required depending on the resolution requirements of the halftone screen.

摘要： The present invention is a super-scalar method and apparatus for the generation of halftone dot patterns in an image processing system. The super-scalar design employs at least one block of memory for the storage of at least one predetermined halftone dot pattern across a plurality of unique locations therein, and a sequencer for producing an index into said memory as a function of the position of the pixel along a scan line and the halftone dot characteristics. Also included is addressing circuitry for memory access control, to combine the index produced by said sequencer and a pixel value for the pixel to produce a memory address, the memory address being thereby employed to access one of said locations in memory and to cause said memory to output a signal representative of a portion of the halftone dot pattern stored at the unique addressed location.

摘要： A method and system is provided for splitting a print job into its preamble and at least one chunk. The splitter maintains a collection of RIP node addresses to which chunks of the job currently being split have already been sent. When a new chunk is about to be sent, the splitter checks whether each RIP node address has already received a chunk. If the RIP node has not already received a chunk, the splitter sends the preamble as well as the chunk to an available RIP associated with the RIP node. If, however, the RIP node address has already received a chunk, only the portion of the chunk after the preamble is sent to an available RIP associated with the RIP node and communicate the location of the preamble to the available RIP node. The preamble may contain common content for each job.
摘要翻译：提供了一种用于将打印作业分解成其前导码和至少一个块的方法和系统。分配器维护目前正在拆分的作业块已经发送到的RIP节点地址的集合。当新的组块即将发送时，分片器会检查每个RIP节点地址是否已经收到一个块。如果RIP节点尚未收到块，则分离器将前导码以及该块发送到与RIP节点相关联的可用RIP。然而，如果RIP节点地址已经接收到一个块，则只有前导码之后的块的部分才被发送到与RIP节点相关联的可用RIP，并且将该前导码的位置传送到可用的RIP节点。前导码可能包含每个作业的常见内容。

摘要： There is disclosed in embodiments methods relating to the compression of printing hints. The method in embodiments generates a first set of image pixels having corresponding printing hints. The printing hints are then adjusted to produce a second set of image pixels processed in such a way that an end printed result is visually equivalent to a printed result using the first set of image pixels thereby reducing the entropy in the printing hints. The method improves the compression ratio of an image using printing hints by adjusting the printing hints of pixels that are zero or fully saturated. The printing hints are adjusted in such a way to reduce the complexity of the printing hints.

摘要： Provided is a method for enabling accurate and consistent imaging of selected colors within a document for various printing device configurations utilizing an automated spot color editor. The method includes determining appropriate target values for a selected color within a print job. The automated spot color editor modifies or adjusts the selected color by selecting a quality level, in the form of a color difference metric, and a maximum number of iterations, which is the maximum number of times the automated spot color editor is operated to calculate a CMYK color formula. Sample patch(es) are printed and analyzed for the selected target value and a CMYK color formula based on the color composition of the sample patch is calculated. The CMYK color formula is inserted into a spot color editing table. Through a graphical user interface, an operator may review the color formula for acceptance.

摘要： In an image rendering system, a method of compensating for system performance changes related to image attributes includes rendering a diagnostic image, sensing at least one image quality from the diagnostic image, updating an image attribute compensation tone reproduction curve based on the sensed image quality and rendering an image based on the updated image attribute compensation tone reproduction curve. For example, image attributes include print media type and a halftone screen selection. An image processing system operative to perform the method of compensation includes a set of image attribute compensation tone reproduction curves. Each curve of the set is associated with a particular combination of image attributes. For example, each curve is associated with a particular media type/halftone screen combination.

摘要： A halftone cell is composed of a plurality of pixel groupings predefined to correspond to optimal tone level gradations. Selected output pixel groupings vary in number, and in shape of subpixels used from other pixel groupings, in order that successive input levels correspond to successive halftone cells defining substantially equal changes in a measured darkness value. Tone level gradations are optimized by purposeful correlation of input levels to output levels, especially where the number of output levels exceeds the number of input levels. During optimization, a calibration sample is produced by the image output device and calibration elements are empirically measured. Darkness change between successive levels is calculated and compared. Where the percentage of darkness change exceeds a desired amount, additional calibration elements are produced until the change calculated between successive levels is substantially the same. Successive input levels are associated with successive output levels such that a change between any adjacent input levels produces a change in darkness in the desired amount. The correlation is stored in a look up table for use during operation of the image output device.
