    摘要: Digital halftoning processes for producing a halftone image include, for each pixel in the image: indexing a two-dimensional look up table using a position of the pixel, identifying a threshold value for the pixel from the two-dimensional look up table, creating an index that indexes a three-dimensional lookup table using the threshold value and the position of the pixel, and obtaining an output value for the pixel from the three-dimensional look up table via the index. The digital halftoning processes also produce a halftone representation of the image from output values for corresponding pixels.

    摘要: A multiple beam printer system having N laser beams receives print job information from a print host. A rendering application uses a threshold array to generate halftone image data from the print job. The threshold array is defined based on a spot function. The defined screen is non-orthogonal and includes Y pels in a direction that is perpendicular to a scanning direction of the laser beams where Y is an integer multiple of N. A distance between screen dots in pels is preferably equal to an integer multiple of N. The screen dot may be defined by a supercell encompassing two screen dots and having an odd number of pels in a direction that is parallel to the scanning direction. The spot function may include a snap feature that snaps a screen dot to the nearest printer grid pel. The spot function may include scaling to compensate for the distortion of the non-orthogonal screen dot.
