  • Patent number: 8693016
    Abstract: Systems and methods are provided for error correction in a parallel RIP environment. The system comprises parallel RIPs and a serial RIP. The system receives a print job comprising logical pages, separates the print job into segments of logical pages, and distributes the segments to the parallel RIPs for interpretation and rasterization. The system further determines that a parallel RIP has encountered an error indicating that a segment includes multiple logical pages, and instructs the serial RIP to rasterize the segment responsive to detecting the error.
    Type: Grant

  • Publication number: 20120314240
    Abstract: Systems and methods are provided for error correction in a parallel RIP environment. The system is operable to receive a print job comprising logical pages, to separate the logical pages into segments, to distribute the segments to parallel RIPs for interpretation and rasterization, and to transmit the segments to a serial RIP for interpretation. The system is further operable to determine that a parallel RIP has encountered a dependency error that prevents the parallel RIP from rasterizing one of the segments, and to instruct the serial RIP to rasterize the one segment responsive to detecting the dependency error.

  • Publication number: 20120194831
    Abstract: Systems and methods for using conversion arrays to transform image in print jobs to different color depths. In one embodiment, the system stores a plurality of conversion arrays for converting images of print jobs encoded according to a page description language. The system receives a print job encoded according to the page description language, locates an image in the encoded print job, and identifies an existing color depth of the image, a pel color range, and a desired output color depth for the image. The system further selects a conversion array from the memory based on at least one of the existing color depth of the image, the pel color range, and the desired output color depth, and converts the image from the existing color depth of the image to the desired output color depth using the conversion array. The system further transmits the converted image for printing.
