Abstract
A method is described for exposing both sides of a light sensitive sheet such as a printed circuit board panel according to imaging data. The method uses a device that has an optical system for scanning the sensitive sheet by one or more beams. The optical system scans both sides with the scan lines on one side mutually positioned with respect to the scan lines on the other side. According to one implementation, the optical system includes two optical scanning units driven by a single source, with a switch alternating the beam from the source to one then the other optical scanning unit.
