Abstract
Imaging system and method suitable for producing artwork masters for use in the manufacture of printed circuit boards. A beam of coherent radiation is modulated in accordance with data from a source defining the image to be produced, and the modulated beam is scanned across an output medium to form the desired image. A reference signal is generated in accordance with the position of the beam on the output medium, and this signal is shifted forward in phase to compensate for any delay between the generation of the reference signal and the arrival of the modulated beam at the output medium.
