摘要: An improved photographic composition system utilizes a pulsed light source which projects beam of through character outline on font strip to produce an image is reflected by mirror onto sensitive sheet. The distribution based three factors: first the frequency occurrence each character, second adjacent characters, and third rotational speed drum carries strip.
