Abstract
A retractable in-line inking/coating apparatus selectively applies either spot or overall ink/coating to a blanket or flexographic plate on a blanket cylinder or spot coating or overall ink/coating to a flexographic printing plate on a plate cylinder in a rotary offset printing press. The inking/coating apparatus is pivotally mounted on the tower of a printing unit or dedicated coating unit, and is extended into and retracted out of inking/coating engagement by a carriage assembly which is pivotally coupled to the printing unit tower. Because of the pivotal support provided by a cantilevered support arm, the inking/coating apparatus can be raised and lowered through a Ferris wheel arc movement between adjacent printing units. The aqueous component of the printing ink or coating is evaporated by a high velocity, hot air interstation dryer and a high performance heat and moisture extractor so that the ink on a freshly printed sheet is dry before the sheet is printed on the next printing unit. Thus, flexographic ink or coating applied at the first printing unit can immediately be overprinted on subsequent printing units.
