Abstract
In an apparatus for decorating stiff articles using a screen printing process, an object carried by an object carrier and the stencil are advanced synchronously along a transport path during a printing operation. A doctor co-operable with the stencil is movable in an opposite relationship to the direction of movement of the stencil and the object. In the region of the at least one screen printing station is a transport screw with at least one screw flight as a drive for the object carrier, which is in engagement with the screw flight of the screw. During a printing operation the object carrier with object, on the one hand, and the stencil, on the other hand, pass synchronously through an acceleration phase and a deceleration phase. The printing stroke of the stencil is less than the total stroke thereof in the direction of movement of the object carrier.
