Abstract

An external drum laser imagesetter providing one or more imaging beams. The drum is rotated in a fast scan direction and the one or more beams are modulated while the beams are moved in a slow scan direction. In one embodiment, the imaging beams are deflected in a slow scan direction to compensate for the spiral advance.
