SYSTEMS AND METHODS FOR OPTIMIZATION OF PARAMETERS FOR EXPOSING FLEXOGRAPHIC PHOTOPOLYMER PLATES

摘要

Systems and methods for exposing photopolymer printing plate material located within a target area having first and second dimensions. A light source having LEDs arrayed coextensive with the first dimension moves relative to the second dimension, and emits different light intensities over the target area in at least one of the first dimension or the second dimension. The systems and methods may be used to determine exposure parameters for curing a selected plate by causing different sample units to receive different amounts of total energy exposure, exposure energy per exposure step, or a combination thereof, and visually evaluating each sample unit against a reference plate of the same type and thickness. The sample unit embodying a minimum acceptable total exposure energy and a maximum acceptable exposure energy per exposure step is then identified.
