Abstract (en)
[origin: US4570539A] The ink dosing elements in the ink fountain of a printing machine are adjusted to reference positions in response to measurement of the amount of ink applied to the fountain roller at the respective inking zones. The reference positions are stored in a data memory for future use or are adjusted in accordance with predetermined values to arrive at the settings of the ink dosing elements for obtaining a desired ink profile. Preferably an optical densitometer mounted on a rail parallel to the fountain roller measures the amount of ink, and the densitometer is initially calibrated at an ink-free zone on the fountain roller. According to a manual embodiment, a first one of the ink dosing elements is brought to a reference position by an operator while viewing the respective inking zone, for example, to obtain a permissible minimum of ink. The densitometer is moved to measure the ink at the first inking zone, and is successively moved to measure the ink at the other inking zones while the respective ink dosing elements are adjusted to obtain substantially the same measured values for all of the inking zones. Alternatively, the method is performed by a remote control computer.
Abstract (de)
Es wird ein Verfahren zum Einstellen des Farbwerks einer Druckmaschine mit mehreren Farbdosierelementen (2-10), deren Abstände zu einer Farbkastenwalze (1) unabhängig voneinander einstellbar sind, beschrieben, bei dem der Farbauftrag auf die Farbkastenwalze in den einzelnen Farbzonen (2'-10') mittels eines Densitometers (12) zonenweise gemessen wird, wobei die Farbdosierelemente (2-10) nacheinander so weit verstellt werden, bis der gemessene Farbauftrag in allen Farbzonen gleich ist. Als Meßvorrichtung ist ein Densitometer vorgesehen, dessen Tastkopf (12) auf einer Schiene in konstantem Abstand entlang der Farbkastenwalze (1) bewegbar ist.
