摘要： A printing system is disclosed. The printing system includes a color management unit including one or more color caches to store input colors and corresponding output colors and a color engine (CE) to receive input colors and perform Force-K transformations to map near black input colors into pure black output colors by dynamically identifying the near black input colors based on chroma values and effective output values.

摘要： Embodiments described herein provide for the reuse of some locations in a hash table of color conversions during processing of a print job, while preventing the reuse of other locations. If a determination is made that the hash table is to be re-initialized, then the locations in the hash table that are marked as non-persistent are marked as saved to allow them to be reused, while the locations in the hash table that are marked as persistent are prevented from being reused. During processing of the print job subsequent to re-initialization of the hash table, if a color in the print job does not have a color conversion, then a location in the hash table is identified that is marked as saved. If the location stores the color conversion for the color, then the non-persistent mark is restored for the location to bypass performing a color conversion for the color.

摘要： A method is disclosed. The method includes receiving one or more images of bitmap data applied to a print medium as print medium image data, register the print medium image data to the bitmap data, detecting one or more candidate defects based on whether a difference between the print medium image data at a location and the bitmap data at the location exceeds a predetermined threshold, detecting one or more defects among the candidate defects and transmitting information about the one or more candidate defects classified as defects.

摘要： Systems, methods, software for monitoring usage of a recording medium in an image forming apparatus. In one embodiment, a usage monitor receives a raster image, and identifies thresholds that distinguish different intensity levels reproduced by different drop sizes of the recording material. The usage monitor identifies a set of pixel values for a block of pixels from the raster image, performs a vectorized comparison of the set of pixel values to each of the thresholds to generate sets of comparison bits, determines a number of set bits in each of the sets of comparison bits, and updates a threshold counter for each of the thresholds based on the number of set bits. The usage monitor may then compute drop counts for different drop sizes based on the threshold counter for each of the thresholds.
