摘要： A halftoning method and apparatus reduces the occurrence of unaesthetic color print output associated with the different relationships found in the numeric data contained within the color data planes. The calculation, modification and distribution of error values, resulting from the mismatch between color plane values and firing thresholds, are performed in a manner that minimizes unaesthetic conditions. Error values are modified by use of error modification functions, bitmaps and matrixes. Firing decisions are based on a comparison of the modified error.

摘要： A method for compensating for induced artifacts on an image to be printed includes processing the image to be printed. An image region of the image susceptible to at least one artifact is identified. An imaging process is modified to reduce an effect of the at least one artifact on the image region. The image is printed.

摘要： An embodiment of a halftoning method reduces the grainy appearance resulting from overlap of cyan and magenta colorants using a single threshold matrix for both the cyan and the magenta color planes. The cyan color value and the magenta color value for a pixel are summed. If the sum is greater than the maximum possible color value by at least the corresponding matrix threshold value, both cyan and magenta colorants are placed on the pixel. If the sum is not greater than the maximum possible color value by at least the corresponding matrix threshold value, then the smallest of the cyan color value and the magenta color value is compared to the corresponding matrix threshold value. If this smallest color value is greater than the corresponding matrix threshold value, the corresponding colorant is placed on the pixel. Otherwise, the other colorant is placed on the pixel. If the sum is less the maximum possible color value, then the sum is compared to the corresponding matrix threshold value. If the sum is greater than the corresponding matrix threshold value, colorant will be placed on the pixel. The smallest of the cyan color value and the magenta color value is compared to the corresponding matrix threshold value. If this smallest color value is greater than the corresponding matrix threshold value, the corresponding colorant is placed on the pixel. Otherwise, the other colorant is placed on the pixel.

摘要： One or more ink-usage parameters are adjusted based on ink remaining and historical ink usage, to reduce ink usage for an image to be printed on a sheet of media with ink. The image is printed on the sheet of media with the ink, in accordance with the ink-usage parameters. Adjustment of ink-usage parameters and printing an image on a sheet of media with the ink are repeated for each additional image to be printed on a sheet of media.
