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.

Abstract: The invention is for color separation orientation gauges and methods by which they are used to produce a finished print in more than one color, the colors used being the primary colors and black. In the printing trade, the primary colors are at times referred to as magenta, yellow, and cyan. The color magenta is basically red, cyan is basically blue and, of course, yellow is basically yellow.The gauges utilized are provided with a predetermined number of dots disposed at various angles depending, for example, on the color to be eventually printed, which gauges are superimposed on a half-tone mask of which there are also a predetermined number of dots which are practically invisible to the naked eye. The gauges of the two embodiments of the invention are provided with special reference line dot densities and angles and legends to provide the color stripper with easy to use compact gauges for producing multi-color prints.
