Programmed Automatic Imposition with the Opti-Copy Full Size Imposing Camera.

In large format lithography the one area of prepress which has defied automation over the years has been the function of stepping film into an imposition as a preliminary to plate-making. Several new systems have made their appearance in the last year to break through this impasse. The method described herein uses a tape controlled camera, which converts loose individual pieces of copy directly into one-piece film flats or plates. This system is capable of handling 150 line halftones easily including top quality color separations as well as the most demanding line work.
