Pre-coated microscope slides are produced on a large scale by spraying a dyestuff solution on to microscope slides which are passed at a constant speed under a spray nozzle, the pattern of which is kept rectangular by means of a mask. Apparatus for carrying out the process includes a conveyor belt, a regulatable spraying device positioned above the conveyor belt and a mask positioned between the spraying device and the conveyor belt.
