Abstract
A process for constructing a printing plate by successively depositing a plurality of n layers of photopolymer on a substrate, curing each layer 1 through (n-m) using a wide area radiation source, and selectively curing layers (n-m+1) to layer n using a small area radiation source modulated in accordance with a desired image to be printed by the printing plate. Non-cured polymer is removed from layers (n-m+1) to n, and all of the layers are further cured with a detacking area radiation source. Also disclosed is a system for constructing a printing plate by additive manufacturing, including a printing assembly and means for providing relative motion between the substrate and the printing assembly. The assembly comprises one or more ink jet print heads, at least one wide area radiation source, and the small area radiation source.
