Abstract
A method of manufacturing a flexographic printing plate includes exposing a bottom side of a flexographic printing plate substrate to UV-A radiation for a first exposure time. A top side of the flexographic printing plate substrate is exposed to UV-A radiation through a thermal imaging layer. The bottom side of the flexographic printing plate substrate is exposed to UV-A radiation for a second exposure time. The flexographic printing plate substrate is developed. The flexographic printing plate is cured. A sum of the first and second exposure times set a relief depth.
