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.

摘要： Apparatus and methods for adjusting a skew angle of an LED array in the second of dual/tandem print engine systems to compensate for shrinkage of the printable medium exiting the first print engine. Features and aspects hereof provide for manually and/or automatically measuring the shrinkage of the printable medium as it exits the first print engine and for automatically and/or manually adjusting the skew angle of the mounting of the LED array in the second print engine. The image data applied through the LED to the corresponding photoconductor of the second print engine is similarly skewed to match the skew angle of the LED array. Thus a substantially normal bitmap image is applied through the skewed LED to the photoconductor of the second print engine shrunk in the width dimension. Visual artifacts and anomalies from the mathematical approximations and rounding are visually imperceptible at sufficiently high resolutions.

摘要： Systems and methods for selectively powering multiple microwave energy sources in a dryer of a printing system. One embodiment is a microwave dryer that includes microwave energy sources configured to generate electromagnetic energy to dry a wet colorant applied to a continuous-form print media by a printer. The microwave dryer also includes waveguides configured to transport the electromagnetic energy. The waveguides include a passageway to pass the print media through the waveguides as the print media travels along a media path. A long axis of each the waveguides are positioned in a direction along the media path, and each waveguide is coupled to a different microwave source to section the electromagnetic energy into regions that are distinct from one another in a direction across the media path. The microwave dryer further includes a controller configured to regulate a power output for each of the microwave energy sources.

摘要： Embodiments of the invention disclose a method for K-only (gray/black) object rendering in a high-speed color controller of a printing system. The method includes setting a flag to indicate selection of a K-only text and barcode print preference from a user of a print system, receiving one or more objects to be printed by the print system, the one or more objects including at least one of a text object and a barcode object, determining whether an input color space for the at least one text object and barcode object should be converted to K-only black ink, and rendering the at least one of the text object and the barcode object as K-only black ink if the input color space is determined to be converted to K-only black ink.

摘要： Force K processing is presented to replace gray color values of input data with only levels of black ink/toner when color management is not specified in the print job. A system converts input data of a print job to a CMYK color space of a printer by processing a lookup table of color values for the color space of the input data based on a detected color space of the input data to identify gray color values of the lookup table. The system also determines that these gray color values produce an output in the CMYK color space of the printer that includes one or more of cyan, magenta, and yellow color components. The system replaces the gray color values with black color values and corresponds the black color values of the lookup table with gray color values of the input data for conversion of the input data.
