Abstract
An optical imaging apparatus (80) for direct engraving of flexographic plates (52) includes at least two laser sources (43), each emitting laser beams (44). A mirror or prism (45) is placed in front of each of the laser sources to alter an optical path of each of the laser beams. The laser beams cut the flexographic plate at different depths and cut out chunks (65) of the flexographic plate.
