An apparatus for obtaining accurate registration of objects of revolution allowing multicolor printing of such objects by a screen printing apparatus, including a chuck for centering and mounting such objects, and a motor driven pulley and belt system to rotate the chuck and the object to a designated reference position prior to printing in which the pulley associated with the chuck is generally cylindrical in configuration, having a smooth, even surface which comes in contact with only a portion of the belt driving it to thereby reduce the frictional forces between the belt and the pulley and permit the pulley and belt to move relative to one another for printing, once the desired reference position has been obtained.
