    摘要： A computer-implemented method of matching color elements for objects having different source color definitions within a print job prior to printing, includes identifying all source colors to be printed within the print job and object type associated with each instance of a source color; identifying any source colors having at least two different source color definitions; for each source color having at least two different source color definitions, selecting one of the source color definitions in accordance with a predetermined criterion; and assigning the selected source color definition to at least one other instance of the source color for that object type. The predetermined criterion may include for each source color having at least two different source color definitions for the same object type, assigning the selected source color definition to all other instances of the source color for that object type.

    摘要： A method of identifying color mismatches for objects having different rendering intents within a print job prior to printing, includes identifying all objects within the print job, each object's type, rendering intent and all source colors associated with it; for each object in the print job, transforming each object's source colors using a prototypical color transformation; identifying sets of transformed objects having source colors that match within a first tolerance; transforming all transformed objects using a target printer's color space; identifying any of the transformed objects in each set that do not match within a second tolerance level; identifying any object types within the group of mismatched objects having at least two different rendering intents; selecting one of the rendering intents in accordance with a predetermined criterion; and assigning the selected rendering intent to at least one other instance of that object type.

    摘要： A system/method of color match assessment for electronic documents includes receiving digital data defining a composite electronic document including a raster image object having an edge and a color graphics object bordering the edge of the raster image object. The pixel color values defining the edge of the raster image object are processed to estimate a local color variance of the pixel color values. The local color variance is used to determine if the edge can be color matched to the bordering color graphics object. If the edge can be color matched, a match color for the edge is derived. The match color is associated with the digital data defining the electronic document so that a downstream object color match system can use the match color as needed, e.g., to adjust the color of the bordering color graphics object to ensure a match with the edge of the raster image object when the electronic document is printed using a xerographic printing process.

    摘要： This invention is a method of producing a set of TRC's for a color printer's secondary halftone screens that is correlated with the printer's primary halftone screens. The method makes use of the printer/screen characteristic data that is normally gathered during screen calibration. However, instead of progressing from the data to a normal calibration for the secondary screens, the method goes backward through the data starting with the finished primary screen TRC's. The method insures that for every primary screen density, the closest possible secondary screen density is used when the same digital value is specified.

    摘要： A method for remote proofing a digital press by performing the color rendering of a specific DFE and printer, including taking into account job and printer settings, while maintaining vector objects is described. In one exemplary embodiment, the method color renders a file to a PDF/X-1 format to enable a portable proof-ready file, independent of the target print system. The PDF/X-1a's output intent tag identifies the intended print condition within the file. The rendered PDF/X-1a file can be sent to any device that supports the PDF/X standard and automatically convert colors from the output intent color space to the proofer color space for an accurate hard copy proof. This functionality automates and streamlines the proofing task of the end user because there is no need to find and load the correct ICC profile on the proofing system.

    摘要： A raster image target tracking method, the raster image being a binary raster image or a targeted contone raster image, may include determining target information that corresponds to a target device for the raster image, saving the target information in a memory, comprising the raster image target device to a processing device by which the document is to be processed, and providing a warning message when the document target device does not correspond to the processing device. Also, a compound document analysis and target tracking method may include providing a compound document, analyzing each object of the compound document to determine target information, saving the target information in a memory, comparing the target devices of the respective objects to each other, and providing a warning message to a user when the target devices of the respective objects do not correspond to each other.
