ABSTRACT:
A screen printing press is provided for printing on a web having defined, successive areas and indicia provided in predetermined positions relative to each of the defined areas. The press includes a base defining a work station, a screen supported on the base for movement between a printing position overlying the work station and an interrupted position, and a web handling assembly for advancing the web along a path of travel to successively feed the defined areas of the web toward the work station. A registration system successively positions the defined areas of the web in a desired predetermined relationship to the screen as successive defined areas are brought into a position to be printed. The registration system includes longitudinal, lateral and angular shifting mechanisms for adjusting the longitudinal, lateral and angular alignment between the screen and the web. Sensors are provided for sensing the correct positions and orientation of the indicia that are occupied when the defined areas of the web are in the predetermined relationship relative to the screen, and a controller is responsive to the sensors for controlling the longitudinal, lateral and angular shifting mechanisms to adjust the alignment between the screen and the web until the correct positions and orientation of the indicia are sensed.
