Zusammenfassung:	An apparatus for registering a laser patterned image on a circuit board has a controller operating laser beam source, modulating and scanning components capable of generating, modulating and scanning one or more laser beams across a circuit board held on a support. The controller provides a data signal to the components, the data signal comprising a grayscale image bitmap comprising image pixels having grayscale levels that correspond to fractional beam intensities.
