ABSTRACT:
An adaptive control system is intended for use in conjunction with a printing press to control the setting of an ink control device that regulates the amount of ink applied to a substrate. The control system includes a controller for calculating a new setting for the ink control device based on a measured ink color value and a target ink color value. The controller has at least one gain parameter. The control system also includes a sensitivity adapter in communication with the controller. The sensitivity adapter modifies the gain parameter in response to the sensitivity of the ink control device to a correction in setting issued by the controller. The control system operates so that a measured ink color value on the substrate converges toward a target ink color value.
