ABSTRACT:
Camera ready copy is prepared for each page of a publication. Each page of the camera ready copy is then affixed in an appropriate manner to a special control sheet. The control sheets which are to be used are dependent upon the particular signature size and configuration. The control sheets are specially coded to identify the page of copy and also specially configured to facilitate placement of copy and to provide a means for indexing and orienting the control sheet during the process. After each page of camera ready copy is mounted on a corresponding, appropriate control sheet, predetermined sets of control sheets are then positioned on a platen associated with a photo negative apparatus. A photograph is taken of the copy on those sheets. The fully developed negative represents a signature or a portion of a signature wherein the camera ready copy has been photographed and prealigned in such a manner that the negative itself is substantially ready for a printing plate.
