Abstract
A method of making a relief image printing element comprising a plurality of relief printing dots. The method includes the steps of imagewise exposing at least one photocurable layer to actinic radiation to selectively crosslink and cure portions of the at least one photocurable layer; and developing the relief image printing element to separate and remove uncrosslinked and uncured portions of the at least one photocurable layer to reveal the relief image therein. The at least one photocurable layer includes a photoinitiator exhibiting a quantum yield of initiation (Qi) of more than 0.05 at a 365 nm wavelength. The substrate has an optical density from 0.5 to 5 in the wavelength range of 365 nm to 450 nm but preferably allows transmission of from 0.1% to 10% of incident light in the wavelength range of 365 nm to 450 nm.
