  • Lithographic press dampening control system
    Patent number: 6796227
    Abstract: A lithographic dampening control system measures the color strength of various tones of ink printed in multiple lateral locations across the width of a printing press to determine optimum dampening and controls multiple dampening control devices. By measuring and correcting for excess or inadequate dampening solution, proper dampening is maintained despite variations such as increased evaporation at machine edges due to heat from bearing friction.
