Abstract: A method for outputting a print job includes accessing a file representing a previously created document at a client computer. The method includes accessing a catalog tree residing in the document and including metadata corresponding with a job ticket embedded in the file for rendering the document. The method includes splitting pages in the document into multiple chunks using a splitter located in the client computer. The method includes splitting by the splitter the catalog tree into a set of branches each corresponding with one of the chunks of the finished document. The method includes embedding corresponding branch information into the each chunk. The method includes generating a package of chunks. The method includes streaming the package to a digital front end (DFE) of an output device.

Abstract: A system and method for optimizing toner usage on an output device capable of rendering in five or more colorants includes receiving a print job for rendering a print job. The method includes generating at least one candidate colorant combination using multiple colorants. The method includes determining at least one factor including (i) a toner usage, (ii) a toner cost, and (iii) an accuracy of the at least one candidate colorant combination for rendering a select object of the print job. The method further includes selecting an ideal candidate colorant combination based on a comparison of the at least one factor with one of a second candidate colorant combination and an original CMYK colorant combination.

Abstract: A method of operating a printer includes reducing a first plurality of coverage parameters in a first continuous tone (contone) pixel by a predetermined amount if a combination of at least two of the coverage parameters is below a predetermined threshold and reducing a second plurality of coverage parameters in a second pixel by a smaller amount if the combination of coverage parameters in the second pixel is greater than the predetermined threshold. The method further includes generating half-tone image data from the first and second pixels and forming printed marks corresponding to the first and second pixels on an image receiving surface.

Abstract: A method of operating a printer includes identifying coordinates in a device independent color space for a spot color, identifying color components in a device dependent full color profile in a printer model for an association between the spot color in the device independent color space and a device dependent color space, and emitting a pattern of colorants with reference to the color components to reproduce the spot color in a printed image. The colorant pattern has a colorant density exceeding a predetermined colorant limit threshold associated with printed colors other than spot colors.

Abstract: A processor receives a print job, identifies possible extension marking materials to use to print the print job, and optimizes the order in which the extension marking materials will be used in multiple printing passes. A user interface outputs instructions to insert, into a receptacle, a first interchangeable supply container containing a first extension marking material that is in addition to base marking materials. A printing engine prints first markings (using the first extension marking material) that comprise a first portion of the print job. The user interface outputs instructions to return the partially printed print media to a sheet supply and to insert a second interchangeable supply container containing a second extension marking material. The printing engine prints second markings (using the second extension marking material) that comprise a second portion of the print job, on the partially printed print media, to produce the finally printed print media.
