AI Technical Summary
The power consumption of printing or coating machines is high due to limitations in drying unit capacity, which is influenced by factors such as printing speed, ventilation power, solvent type, ink or coating material type, substrate type, and thickness, leading to inefficiencies in energy use.
A method to determine the maximum printing speed of each unit and set unit-specific drying parameters, including fan speed, air recirculation rate, and temperature, based on global printing parameters using a predetermined formula or lookup table, to minimize power consumption while ensuring safety and quality.
Reduces power consumption by up to 50% in the drying units of printing or coating machines by optimizing drying unit settings, while maintaining print quality and safety, through precise control of fan speed, air recirculation rate, and temperature.
