摘要： Systems and methods for tuning Key (K) black ink printed by a production printer. In one embodiment, an ink tuning system is implemented in a printing system. The printing system includes a production printer that is operable to print color ink onto a continuous-form medium, and includes a radiant dryer that is operable to dry the ink that is applied to the medium. The ink tuning system identifies areas of K black ink designated for printing on the medium by the production printer, and applies a liquid agent to the areas of K black ink to increase the liquid mass of the K black ink before the medium enters the radiant dryer.

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： 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： 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： Systems and methods for color conversion from one CMYK color space to another CMYK color space. The system receives a color defined by a first coordinate in the first CMYK color space. The system converts the color to a second coordinate for the second CMYK color space, and determines a location in a perceptual color space for each of the first coordinate and the second coordinate. The system further identifies a distance between the locations in the perceptual color space, and reduces the distance in the perceptual color space between the two locations by iteratively revising the second coordinate in the second CMYK color space while holding the black level of the second coordinate constant.

摘要： Non integer scaling of images to reduce artifacts is presented herein. One embodiment includes determining a scaling resolution based on a pixel resolution of the image and a pixel resolution of an output device (i.e., factors of the scaling resolution). The image is converted to the scaling resolution to change (e.g., increase) the pixels of the image by the first factor. A grid is generated to scale the converted image. The grid has a number of sections defined according to the second factor times the pixel resolution of an output device. The converted image is sectioned according to the grid. Each section of the grid includes an integer number of pixels of the converted image. The color values of the pixels of the converted image are averaged within each section of the grid to compute a single color value for each section of the grid and scale the image.

摘要： Methods and apparatus herein provide for automated calibration of multiple printheads used in a multi-pass printing system. Aspects hereof print a plurality of gray scale printed patterns each printed pattern corresponding to a gray scale value for each of the multiple printheads. The printed patterns are then measured to determine the intensity (e.g., optical density) of each of the printed patterns. A measurement function is derived from the measured intensity and gray scale levels used to print each pattern. Calibrated transfer functions are then determined from the measurement function and target function where each calibrated transfer function relates, for a corresponding printhead, an input gray scale level of a pixel in an image to be printed to a calibrated gray scale level to use for the corresponding printhead when operating in multi-pass mode.
