An apparatus for treating objects, in particular cytological or histological specimens, having multiple processing stations and a transport device for delivering the objects into and out of the processing stations, is characterized in that at least one running-water station, having an inflow and an outflow, is provided as a processing station. The platform software is capable of intercepting an attempt by the OS to read a storage location of the disk drive during a process of transitioning the data processing system from an inactive mode to an active mode. The invention determines the continuity of two adjacent frames, to search for frame discontinuity to find out if there is a frame similar to a next given frame. If a remote system 2 or 3, which receives the raster data, prints out on output unit 21 or 31, a color proof whose color is reproduced precisely can be provided.
