Abstract: A device for circulating an ink supply to at least one inkjet print head includes at least two components that are different than the inkjet print head and through which ink flows, such as a pump and a valve for the ink. At least one ink line is connected between the components. At least one section of the ink line is embodied as a channel in a plate. The device advantageously has a compact construction and is easy to clean and service. The device has a high degree of reliability since the number of hose lines is advantageously reduced.

Abstract: A device sets the focus of at least one exposure head on a recording material, in particular a printing plate, in an exposer for recording printing originals. An exposer has an exposure drum for holding the printing plates, and an exposure-head carrier, which contains a carrier plate for holding exposure heads, and a carrier base. The carrier plate and the carrier base are connected such that they can move by a hinge which is disposed on the front side of the exposure-head carrier, facing the exposure drum. The rear of the carrier plate is raised or lowered by a tilting drive, as a result of which the exposure heads are moved jointly and substantially radially toward the exposure drum or away from the exposure drum. The hinge is preferably formed from at least one spring plate.
