A method for creating reusable composite components from interpreted pages of rendered document during dynamic document construction involves first obtaining a list of document components from the page and identifying any non-cached components. The individual reusable document components (RDCs) are cached having been rendered to their respective bounding box dimensions. These RDCs are then permuted into combinations of RDCs and each composite RDC is cached rendered relative to each other in a bounding box of sufficient size to adequately contain the combination. Then, combining RDCs to form composite reusable underlays RULs and caching the composite RULs rendered to full-page size. Any portion of each RDC of each composite RUL falling outside the boundary of RULs full-page size is clipped. If a method renders pages having a combination of reusable components and non-cached components, the first step assesses the page for the possibility of having an underlay-overlay pair. Then a cache of RULs is searched for underlays having the needed RDCs. If the correct RUL is not found in cache then generating a RUL from the page's RDCs and caching the new RUL rendered to full-page size. A full-page size overlay is rendered having the non-cached components. Lastly, given the overlay and given the correct underlay is found in cache then retrieving the underlay and rendering the page therefrom.

Systems and methods for generating a dynamic re-configuration with a DFE imager and caching modules to optimize RIP performance by analyzing pages within the job that collect page with job heuristics and statistics. Enabling the functionality to assess the information, thereby re-configuring a digital printer's imager and caching module dynamically during the job RIP to achieve improved overall RIP performance. Accordingly, a system collects and assesses job statistics across multiple jobs to enable optimum performance over time.

Adobe Postscript's setoverprint and setoverprintmode operations, an imager and Object Optimized Rendering (OCR) technology can be combined to achieve a watermark result by either tagging lower image areas as text or other intents, or by changing color values. Separations from stacked objects are combinable with control over OOR tags and color values to achieve special effects are described. Mechanisms of the present embodiment would provide the option where special areas can either disappear and retain the lower object attributes or modify lower object runs with special effect algorithms.

An apparatus () for processing documents each represented by a document description () encoded in a page description language supportive of reusable data includes a page description language interpreter () that receives the document description () and parses the document description () into document components. An imager (), communicating with the interpreter (), creates image representations of received document components. A reusable document component repository () stores image representations derived from a plurality of processed documents. The reusable document component repository () communicates with the interpreter () and the imager () to supply those ones of the image representations corresponding to selected document components of the processed documents and to receive selected image representations created by the imager () during the processing of documents.

A protocol for communication through a bus controller to control data transfers between a host processing platform and the data bus of a bit map printer. This protocol is optimized for a data bus which connects a number of ASIC accelerator cards in addition to the printer, disk controller, bus controller and other typical system cards. The basic data transfer cycle transfers eight data words on the bus between ASIC's, I/O devices, printer and any other devices.
