Methods, systems, and apparatus for generating and associating meta-data with a final form presentation datastream document where the meta-data is structured in accordance with the datastream component architectures. Meta-data objects ('MDOs') are architected as components of a presentation document and thus are well defined to allow applications to reliably access and process the meta-data contained therein. The MDOs may be associated with other components of the document and are architected to be extensible and flexible while still adhering to an architectural structure. The MDOs may be descriptive (no affect in document presentation) or operational (affects document presentation if processed). Standard types of MDOs may include XML standard information, JDF standard information, PWG standard information, and digital signature information. A variety of standard categories further define typical meta-data forms and applications thereof.

A method disclosed. The method includes receiving a Portable Document Format (PDF) print job file, applying a first transform to generate an Advanced Function Presentation (AFP) image print job data stream and applying a second transform to generate an AFP text print job data stream.

A method, apparatus and article of manufacture for modifying printing based upon direct on-the-fly media characteristic parameters is disclosed. The present invention on-the-fly directly measures a media characteristic parameter and performs real-time print modification in response thereto. The measured characteristic parameters include paper texture and composition, as well as adhesion and penetration of print. The modification of print in response to these measured parameters may allow a customer to maintain observed print quality with lower-cost materials. Adjustments may include the addition of coating, hot rolling, or adjustment of toner concentration. Measured parameters may include mottle, paper texture, and bleed through.

A method and system for providing a halftoned image is disclosed. The method and system comprise scaling the halftoned image by performing pel repetition utilizing an error diffusion algorithm such that artifacts are minimized. According a system and method in accordance with the present invention performs pel repetition using error diffusion technology, so that any resulting 'artifacts' are realized as high-frequency image addition, making them much less visible. A system and method in accordance with the present invention provides adjustability in the computational complexity of the scaling, so that quality can be traded off continuously against the amount of processing power required.

We present a communication system which enables two or more parties to secretly communicate through an existing digital channel which has a primary function other than this secret communication. A first party receives a series of cover data sets, hides a certain amount of auxiliary data in the cover data sets, and then relays these cover data sets containing hidden data to a second party, aware of the hidden data. This second party may then extract the hidden data and either restore it to its original state (the state it was in before the first party received it) and send it along to its original intended destination, or may just simply extract the hidden auxiliary data. There exist a plethora of techniques for hiding auxiliary data in cover data, and any of these can be used for the hiding phase of the system. For example, in a JPEG cover data set, a Huffman table may be modified in such a way as to have no impact on the observable nature of the image, and several such schemes are presented here. Since there are so many ways in which to exploit a particular cover data set for secret communication, it is necessary that the first and second parties have pre-established a set of rules by which they will communicate. There must be agreement on the hiding technique, cover data type and location of the hidden data within the cover.

A method, apparatus and article of manufacture for providing improved print quality regardless of media smoothness is disclosed. Information regarding the smoothness of media is ascertained and the information about the media smoothness is used in the generation of an output. A selectable halftone screen is used in the print device to provide different halftone screens for different media smoothness. The halftoning screens can be changed depending on the roughness of the media being used. Pre-defined halftone screens may be stored and selected for a range of media smoothness. The selection of the pre-defined halftones may be selected by the operator or may be selected automatically by the print device.
