| 摘要 |
The present invention improves over the prior art by providing a method and apparatus for composing typographical artwork on color sensitive photographic medium, which method and apparatus may be of an automated nature. The apparatus comprises an optical projector, a number of type characters recorded on a projection medium, such as a strip of film, for projection by the optical projector onto a projection plane, such as a table surface, and may include an encasing light-tight hood. The identity (e.g. the location on the inventory film strip) of the letters selected to make up the sequence of images projected onto the table surface is recorded and stored in a storage memory together with information indicative of the position of the projected images of each of the selected letters along the two orthogonal axes of movement of the table surface. A servo-mechanism is provided for automatically repeating the projection of the selected typographical characters as recorded in the storage memory at the precise locations recorded for each of the selected letters.
