ABSTRACT:
A device for composing graphics comprising a flash lamp for irradiating portions of strip material through a template when an arm supporting the lamp is moved to an exposure position at an exposure station. The template is pressed against the strip at the exposure station between a resilient frame-mounted pad and a transparent plate on the lamp arm by a toggle linkage between the frame and the arm. The template has a rectangular array of windows and is manually positionable on locating pins at the exposure station for different exposures. A positive image of each window is provided on the template, and the locating pins are movable via movement of the lamp arm from a preview position where the image is at the exposure station so the operator can see where the graphic will be formed to an exposure position with the associated window located at the exposure station for exposure. The template also has a code for each window optically readable by the device so that means in the device will advance the strip material a predetermined distance to provide appropriate spacing between graphics along the strip material.
