This setting instructs the scanner which pattern to use when creating halftone images. The setting affects halftone composition scans and conversions of grayscale images to halftone. The halftone pattern is a 4-by-4 dither matrix that determines the threshold levels at which corresponding dots are represented by black or white pixels. The pattern created by these threshold levels determines the manner in which shades of gray are represented in the scanned image.
