Abstract
In order to achieve a good printed result, it is important that the rollers that interact with each other are arranged at a suitable distance from each other, so that they act on each other with the pressure as stipulated. In order to set the rollers, use is made of a stripe, in particular an ink stripe, which results from contact between the rollers in the rest state. After the transfer, i.e., the formation of the strip, the relevant roller must be rotated into a position wherein the printing machine operator can have access to the ink stripe. As a result of the safety devices provided in printing units, it is generally not possible to detect, however, when the ink stripe on the roller appears in the suitable position. The invention provides a remedy here, in that it is proposed to rotate the roller into the viewable position at a suitable speed, or, by using a special program, taking into account a predefined rotational angle, to move the rollers automatically into the viewable positions.
