A computer generated method disclosed. The method includes receiving a print job data stream, determining if the print job data stream comprises a secure print job, and inserting a control operator to designate a secure print job data stream if the print job data stream comprises a secure print job.

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.

A method is disclosed. The method includes receiving color data for an object to be printed and performing post color processing for each pixel in the object if the object is a graphics/text object, while no processing is performed if the object is an image object. Post color processing is performed by determining if a pixel is black or gray and converting the pixel to K only black color if the pixel is black or gray.

Systems and methods are provided for including sheet images of pre-printed inserts in a print preview for a print job. The system is operable to receive a print job, to receive a request for a print preview of the print job, and to rasterize logical pages of the print job to generate sheet images. The system is further operable to identify inserts to be integrated with printed versions of the sheet images of the logical pages, and to include sheet images of the inserts with the sheet images of the logical pages for the print preview.

Methods and systems are disclosed herein for print data transformation using conversion arrays. A print datastream is received, where the print datastream includes bitmap data encoded as a first number of bits per pel. An array of conversion values is retrieved to convert the bitmap data to a second number of bits per pel encoding. The bitmap data is then converted using the array to the second number of bits per pel encoding, where one or more bytes of the bitmap data is used as an index to the array to generate output data. A printed output is generated based on the output data.

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.
