Dithering is a technique for reproducing halftone images, such as a Dither photo, in binary mode. Two pixel levels are used to represent the entire grayscale, thereby reducing the levels of gray required displaying an image. Using a dithering pattern requires less memory than using a grayscale mode. Choose a dithering method in the Dither drop-down list box: None, Bayer Dither 64 (64 steps), Bayer Dither 16 (16 steps), 45 degree Halftone, 0 degree Halftone, Error Diffusion, and User Download.
