Dither Dithering is a technique for reproducing halftone images, such as a 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. Original Bayer Dither 64 Bayer Dither 16 45 deg. Halftone 0 deg. Halftone Error Diffusion NOTE: You can specify a *.PXH file that uses a different dither pattern. To do this, choose "User Download" in the Dither drop-down list box. Click on the More button in the Scanner Settings dialog box to access the Scanner Special Features dialog box. Click on the Dither button in the Download From File group box in the Scanner Special Features dialog box and select a dither pattern file in the file selection box. A-63055 December 1999 8
