Document describes a laser projection and printing system wherein a laser beam is focused on the scan center of an X-Y galvo-deflector, passes through a condensing lens to a transparency to be projected, and is transmitted to an imaging lens for projection to a large format plate. The scanning galvinometer, condenser, and imaging lens render the laser beam effective to project the small transparency to a large format plate. Author
