Abstract: A method of producing a relief image printing element from a photocurable printing blank. The method includes the steps of a) providing a photocurable printing blank, the photocurable printing blank comprising (i) a backing or support layer; and (ii) one or more photocurable layers disposed on the backing or support layer. The one or more photocurable layers are selectively imaged by exposing the layers to actinic radiation to selectively crosslink and cure portions of the one or more photocurable layers, and then developed to remove uncured portions of the one or more photocurable layers and reveal the relief image therein. The relief image comprises a plurality of relief printing dots, including relief printing dots that have a rounded top and relief printing dots that have a flat top.
