Reducing back-reflection during ablative imaging

摘要

A method includes exposing a plate on a support surface of an imager using one or more laser beams, the exposing while there is a metallic screen structure located on the support surface between the plate and the support surface such that the amount of back-reflected radiation is reduced compared to the plate being placed directly on the support structure with no screen between the plate and support surface. An apparatus includes the combination of a base material having the support surface and the metallic screen structure thereon.
