Abstract
A system for curing printing plates with controlled radiant energy sources. A conveyor moves a printing plate through a chamber having energy radiators above and below the conveyor. Power to the radiators is controlled for each radiator or to groups of radiators defining radiation zones. Curing time may be controlled by adjusting power to the radiators and adjusting the conveyor speed. Sensors detect a plate as it enters and exits the chamber. Heat sensors may detect chamber or plate temperatures. A color sensor may detect plate color as an indicator of degree of curing. A computer system stores curing scenarios and uses the sensor signals and operator inputs to control power to the radiators and conveyor speed to provide uniform curing of the plate.
