Abstract
The present invention is directed to a method of selectively pre-exposing a photosensitive printing element prior to imagewise exposure in order to remove oxygen from the photosensitive layer prior to imagewise exposure. The invention is usable in a computer-to-plate process to produce flexographic relief image printing elements.
