Abstract
A graphic camera/platemaker optical system is described having a copyboard for an original subject, a lens, an image plane and a mirror. The copyboard, lens and mirror are independently movable such that they may move in different directions in order to produce a variable scale image or reproduction of the original onto the image plane. The movable elements are positioned by separate stepping drives controlled by a common microprocessor.
