Abstract
A sheet transfer assembly for use above an ultraviolet curing unit in a flexographic printing press used for printing corrugated sheets includes a vacuum plate with heat sinks. The vacuum plate includes openings for rollers that extend through the vacuum plate to drive printed sheets across the bottom of the transfer assembly. Heat sinks are formed on the top surface of the vacuum plate between rollers to remove heat from the vacuum plate. Heat from the UV curing unit is effectively dissipated from the vacuum plate into the air used to hold printed substrates against the rollers in the transfer assembly.
