I'd be interested what you have discovered about photofilms for a home 
made plotter. Let us know anything that converts your cheap laser into 
raster scanning 20um beam projection. I think more  brain power would be 
required to devise software to compensate fringing of the projected beam 
as would to the accurate and well predicted spiral mapping in a drum 
plotter. If one were to build a < 50um resolution photoplotter then the 
only feasible method is with a rotating drum. I'd be interested any 
anyone's thoughts.
