Rotec Hülsensysteme has introduced an automatic cleaning system for photopolymer printing plates.
Using the RPC 1 system, plates are laid on a feed table and then inserted into the gap between the first pair of feed rollers. The rest of the process is completely automatic. Oscillating flat brushes and a cleanser remove ink residue and particles of dirt from the plates. The height of the brushes is adjustable for plates of different thicknesses.
Before the clean plate leaves the system, a pair of press rollers squeeze out any excess liquid. If required, a drying section can also be installed.
