Printing sleeve with an integrated printing surface

摘要

A seamless printing sleeve comprising a hollow cylindrical base and a seamless imageable surface as its outermost layer is described. The imageable surface acts as an integral flexographic printing surface. Preferably the printing sleeve comprises an intermediate photopolymer or resilient polymer layer between the outer surface of the base and the imageable surface. Also, preferably the base is uniformly transparent or translucent to actinic radiation.
