摘要

The method involves mechanically holding the chamber doctor blades (10) in a position in a lockable manner during a printing process. A locking device is detached for short periods in certain time intervals, in which the chamber doctor blades are prestressed against a screen roller (14) to make an adjustment of the chamber doctor blades. The chamber doctor blades are prestressed with a force against a circumferential surface of the screen roller during the periods, in which the locking device is detached.
