ABSTRACT:
An improved digitally imageable relief printing element having an increased direct-cure imaging speed upon exposure to lasers and other digital sources of actinic radiation. The printing elements of the invention comprise a reflective layer beneath a photosensitive resin layer so that instead of being absorbed by the reflective layer, photons of actinic radiation are reflected back up into the photosensitive layer, thereby speeding up the curing rate of the printing element.
