  • Publication number: 20120250095
    Abstract: A method and a printing system for gray balance correction of a printing process include determining first color values at/on a gray axis of a color space of a reference printing process. These first color values determine tonal values describing a corrected gray balance of the target printing process. To avoid wastage and a further proof for gray balance calibration of the printing process, second color values of the printing process, describing the corrected gray balance, are derived from the first color values. The tonal values of the target printing process corresponding to the second color values are determined from first characterization data and the second color values of the printing process. A correction function created from these tonal values describes the corrected gray balance. Determining corrected characterization data is also possible. A printing form is produced and a printing material is imaged by using the corrected gray balance.

    Abstract: A method for generating print data for digital color images uses a division of the images in windows. Each window is characterized as belonging to a predefined class, based on values of pixels in corresponding windows in at least two sub-images that are derived from the color image by a series of image processing steps. These sub-images are, e.g. a gradient sub-image in which the value of every pixel indicates the difference of that pixel with its local neighborhood and a non-uniformity sub-image in which each pixel determined to be comprised in a uniform area is provided with a predetermined value. The percentage of windows belonging to a class is calculated and compared to threshold values to identify an image type. This image type is used to select a conversion method to convert the color image into print data for printing on the printer system.

  • Patent number: 8243337
    Abstract: For (CMYK) (x,y) data, a target-pixel checking unit calculates a target-pixel integrated value a(x,y) from CMYK binary data of a target pixel and a surrounding-pixel checking unit calculates a maximum surrounding pixel integrated value n(x,y) from respective CMYK binary data of surrounding pixels that are adjacent to the target pixel. Based on the target-pixel integrated value and the maximum surrounding pixel integrated value, a comparison determining unit estimates a higher toner pile height. The comparison determining unit adds transparent image data W(x,y) to the input data CMYK(x,y) and outputs output image data CMYKW(x,y) such that the toner pile heights become even.

  • Patent number: 8237735
    Abstract: What is provided herein is a novel system and method which improves efficiency of a color management system performing a gamut mapping function. In one embodiment, a plurality of source colors are examined to determine whether any have changed. If not, then the source profile, the source device model, and the color appearance model have not changed. Next, the primary colors of the destination device are examined to determine whether any of these have changes. If these have not changed, then the destination device profile and the destination device model have not changed. When the source profile, device profile, color appearance model and the device models have not changed, gamut mapping does not have to be performed. The cached gamut mapping data are used instead. The gamut mapping data are used in subsequent mappings between these same two devices. The cached gamut mapping data are used to customize a color response of the destination device.

  • Patent number: 8237962
    Abstract: A method receives a print job and analyzes the complexity of the print job to generate complexity factors. The method performs raster image processing (RIP) on the print job and records the time taken to perform the raster image processing of each page of the print job. This generates “RIP times.” In addition, the method records the size of each page of the print job to generate “page sizes.” Then the method prints the print job and records the time it took to process the print job. Then the method determines how each of the complexity factors, the RIP times, and the page sizes contributed to the time it took to process the print job. This generates “complexity factor time values.” The method prints a report of the complexity factor time values detailing how each of the complexity factors contributed to the time it took to process the print job.
