Abstract: A screen printing method and an apparatus are provided for printing on objects (12) which can be rolled against a printing screen (34). The method and apparatus provide the possibility of printing on the region (13) of the object to be printed upon over the entire periphery thereof, that is over 360°, even when the length of the final overall print image in the peripheral direction of the object is longer than the spacings between the individual objects passing through the printing station. For that purpose, the peripheral surface to which the final overall print image is to be applied is subdivided into at least two portions (13a, b) which are displaced relative to each other in the peripheral direction of the object (12). Each of those portions is provided with at least one individual print (53), wherein a plurality of individual prints applied to the same portion (13a, b) can supplement each other to afford a colored partial print image.
