￿¡ Scanning composition

Function: You can scan using one of three compositions; binary, halftone, or multi-value. Binary scanning records only black and white from the original. Halftone scan- ning records gray shades on the original using a pattern of black and white dots to represent these shades. Multi-value scanning records grays over 16, 64, or 256 levels.

Usage: Use binary scanning to scan images with no gray shading, such as text or line art. Use halftone scanning to scan an image with gray shading such as a photograph, to be printed or displayed on a monochrome device, such as a laser printer.

Use multi-value scanning to scan an image with gray shading, such as a photograph, to be printed or displayed on a gray scale device.
