Assuming you have a suitable UV laser at your disposal, how do you plan 
on directing its beam as accurately controlled pattern on the surface of 
the pre sensitized panel ?

Obviously you would be aiming for a resolution capable of significant 
improvement over the 0.010 inch line and space limitation (while 
remaining reliable) of conventional inkjet/transparency/UV lamp/contact 
exposure.
