摘要：
A method is disclosed for correction of the effects of ink back-flow and lateral flow in the inking system of a web-offset printing press. A plate coverage equation dependent on plate coverage is used to compensate for ink back-flow into the ink reservoir. An ink key distribution function is utilized to correct for the blurring effects of lateral ink spread caused by the action of vibrator rollers. A correction is also made for the ink saturation effect. The method is applicable to an ink key preset system.
