Omet has developed a new plate cleaning system for high quality napkin lines. This system is easy to apply on existing Omet machines, completely eliminating machine stops for cleaning and guaranteeing a constant and continuous high quality print. The cleaning head moves transversally on the printing unit and is adjustable for all functions: shift speed, number of seconds in cleaning activity and time interval between a cleaning intervention. All these adjustments allow fitting the type of printing plate, the type of ink and the dirt quantity that paper transfers onto the plate. The solution coming out under pressure from the nozzle strikes the plate and is immediately exhausted and re-conveyed into special containers without any environmental problem.
