摘要： In summary, the present invention provides a method, apparatus and program product for calculating an estimate of the amount of toner coverage required for printing print data defined in a compressed data stream. The estimate is obtained with reduced processing by obtaining coverage data from a partially decompressed formed of the data stream and using this to obtain the coverage estimate, thus removing the need to do a full de-compression of the data stream. For example the coverage data is a count of toned pixels for at least one intensity level.

摘要： Methods and systems herein provide for reducing artifacts during printing. One printing system is operable to prepare a continuous tone image (CTI) for printing onto a print medium by generating an initial half tone image (HTI) based on the CTI. The printing system includes a printer and a print controller. The print controller filters the initial HTI and the CTI with a perceptual filter and determines an error between the filtered CTI and the filtered HTI. The print controller prints the HTI via the printer to determine printer artifacts and processes a scanned version of the printed HTI to determine an error between the filtered CTI and the scanned and filtered HTI. This processing updates the initial HTI and reduces the error between the filtered CTI and the filtered HTI.

摘要： Methods and systems herein provide for print data compensation for a print head based on a lateral offset of a media relative to the print head. In one embodiment, a print controller of a printer identifies an edge of a media that is parallel to a direction of travel of the media, and determines a lateral offset between the edge of the media and a print head of the printer. The print controller then modifies data for the print head based on the lateral offset to compensate for a lateral motion of the media relative to the print head.

摘要： The systems and methods presented herein provide for calibrating a print engine of a printing system. The printing system prints image data on a print medium and scans the printed image data. Color values of the scanned image data are then measured and various tints of color values and their transition locations are identified. A calibration module estimates the original optical densities of the identified color value tints and generates a target optical density for each of the identified color value tints using the estimated original optical densities to determine print irregularities in the color values of the scanned image data. The calibration module then generates a halftone screen based on the mean optical densities and applies the generated halftone screen to the print engine to calibrate the print engine.

摘要： Methods and systems herein provide for the color conversion of image data with various levels of gray values, such as text. Such color conversion includes generating a CMYK conversion model by defining a gray region in the perceptual color space of the image data to convert the gray values of the gray region to a range of K values during CMYK color conversion of the image data and segmenting chroma values in a color lookup table that maps perceptual color values to CMYK color values. Lightness values in the color lookup table are adjusted using a perceptual model (e.g., a Heimholtz-Kohlrausch Effect model) based on the segmented chroma values to substantially maintain a lightness relationship between the gray values of the image data and the remaining color values of the image data. The image data is the converted to a CMYK color space using the generated CMYK conversion model.

摘要： An printer, such as a state of the art a high performance, electro-photographic printer. The printer includes at least one smart material sensor enclosed in the printer enclosure that monitors for the presence of a contaminant (e.g., toner or developer) above a selected threshold. Each smart material sensor is coupled to a control unit by a sensor driver coupling. When a smart material sensor finds that a contaminant is present the control unit may indicate the finding on a printer display and/or change operating mode.
