Abstract
In a rotary press, temperature of a printing plate is sensed by an infrared temperature sensor mounted in close proximity to a cylinder carrying the printing plate. Sensor output is used to control a closed loop of a water circulating system which includes one or more water-carrying rollers in an ink train. A water cooler and a water heater are provided in the closed loop and are controlled in response to the sensor output to maintain the printing plate at a temperature which allows proper inking thereof.
