Abstract: A printing system accurately prints proprietary marks and selected colors. A dictionary of recognizable patterns and defined colors corresponding to the proprietary marks and selected colors is linked to a user interface wherein a user may designate a location within a document and at least one of the proprietary marks with defined colors from an accessible menu. A processor associates the defined colors with the image at the specified location and generates a printer signal representative thereof. Alternatively, the processor includes a pattern recognizer for identifying recognizable patterns within a document. The patterns have a likeness to defined patterns within a pattern dictionary and can be converted to the defined patterns for display or imaging.

Abstract: Undercolor reduction is performed to a color image that is to be marked to reduce an amount of marking material used to mark underlying colors in overmarked pixels where a top color is marked over at least one underlying color. Information is generated to designate the overmarked pixels. This information may be generated as tags. A raster image is created in which both the underlying and top colors are included in the overmarked pixels. The image data of the raster image is modified such that an amount of marking material used to mark the at least one underlying color in each overmarked pixel is reduced.

Abstract: A system encodes a separate assist channel that carries only a small amount of additional information in a hardcopy document to compensate for failure of an OCR system to accurately reconstruct a scanned electronic version of the hardcopy document. After the OCR system produces an interpretation of the scanned electronic version of the hardcopy document, a rewrite system that is guided by the assist channel operates independent from the OCR system to correct decoding errors produced by the OCR system.

Abstract: An electrostatic actuator includes a segmented flexible membrane associated with individually addressable electrodes, one for each membrane segment. The electrodes are provided beneath a corresponding one of the membrane segments to define a plurality of actuator chambers between each of the electrodes and the corresponding membrane segment. Control electronics independently provide a bias voltage to select ones or all of the electrodes to generate an electrostatic field between any bias electrode and the corresponding membrane segment to attract the corresponding membrane segment toward the respective electrode. Upon elimination of the bias voltage, the corresponding membrane segments are elastically restored to their previous position. This structure can be incorporated into a fluid drop ejector to achieve variable drop size by control of the number of segments actuated.

Abstract: A print management system includes a policy that determines a protection level for a document to be printed. The document is printed using forgery detection and deterrence technologies, such as fragile and robust watermarks, glyphs, and digital signatures, that are appropriate to the level of protection determined by the policy. A plurality of printers are managed by a print management system. Each printer can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed and the print management system routes the print job to a printer that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can verify that a document is a forgery and/or tracing information that identifies the custodian(s) of the document and restrictions on copying of the document and use of the information in the document are included in the watermark that is printed with the document information.

Abstract: A multiple-LED sensor is used to detect area coverage of marked patches on a marking substrate. The same sensor may also be used for color calibration. The marking substrate area coverage sensor obtains reflectance measurements from marked patches of a marking substrate. For example, the marked patches may be patches of a marking substance such as toner, ink or paint, or patches marked by etching or the like. A Neugebauer model may be used to obtain the reflectance measurements. A batch least squares algorithm may be used to estimate the appropriate parameters of the Neugebauer model. For improved accuracy, a recursive least squares algorithm may be used. The recursive least squares algorithm allows the marking substrate area coverage sensor to calibrate itself to changes in the sensing environment.

The system includes one or more subsystems, including a tone reproduction subsystem that creates one or more print calibration pages, each having a tone curve defining a relationship between a plurality of input color levels, output color levels and a level of measured darkness.

Further, a gamma correction system performs gamma correction on a selected tone curve of one of the print calibration pages by associating each input color level with one of the output color levels based on the desired percentage change in the level of measured darkness in a substantially flat region of the selected tone curve.
