Abstract
A system and method is disclosed that provides an automated, flow-through, dual side, laser direct imaging process and apparatus. This provides the capability to simultaneously register and image both sides of a substrate in a continuous flow-through process. The present invention provides efficiency improvements over the prior art on several levels. First, the prior art is batch process in which substrates are imaged one (or a batch) at a time in contrast with the present invention is a continuous, flow through, sequential process whereby a first substrate is followed into the apparatus by a second substrate which is, in turn followed by a third and so forth and the second substrate begins the process through the apparatus before the first substrate completes the process through the apparatus. Second, the process time per substrate is reduced as compared to the prior art.
