Abstract
Describes the 3 types of image which may be scanned: photographic originals, half toned images and other illustrations usually known as line art. Explains how print produces an illusion of continuous tone. Describes how the resolution of half tone images is measured and how continuous tone images are converted by scanning software to half tones
