Enhanced error diffusion by using directional guided line thresholding |
摘要 |
A method for error diffusion in digital printing. The method selects a base threshold value for printing of digital data, determines an offset value, and then calculates at least two threshold values from the base threshold value and the offset value. The thresholds are applied to the image along directional guided threshold lines, with each set of lines for each color having a unique angle to the lines for the other colors. The error diffusion process does not result in objectionable artifacts.
