Abstract:
1. A method for adjusting an inking device comprising the following steps: providing a reservoir of ink and an ink film pick-up roller having a first shaft; transferring ink using an inking fountain roller, which defines a printing width, from the ink reservoir to the ink film pick-up roller, the inking fountain roller being in contact with the ink in the reservoir and the ink film pick-up roller, the inking roller having a second shaft; evaluating with a detector the actual distance between the inking fountain roller and the ink film pick-up roller within the printing width and/or of detecting an angular displacement of the first and second shafts relative to each other and providing an output signal representing the angular displacement; determining the actual distance between the ink film pick-up roller and inking roller at least at two points of the printing width and/or determining the actual angular displacement of the first shaft and second shaft relative to each other; displacing the first shaft relative to the second shaft by reducing the actual angular displacement and/or by modifying the relative radial position of the first shaft relative to the second shaft; determining a lithographic offset value of at least one adjustment screw; and storing the lithographic offset value determined in this manner in a memory.
