Abstract
A relief printing plate is made by exposing a photopolymer layer on a support sheet to image forming projected light radiation and then removing the unexposed portions of photopolymer. The image forming projected light radiation is provided by passing ultraviolet light radiation, which has been passed first to homogenizing means and then condensing means, through image bearing means out of contact with said photopolymer layer to a projection enlargement means which projects the resultant image upon the photopolymer layer at a predetermined ratio of enlargement greater than 1:1.
