Abstract
Abstract A screen printing press utilizes a continuous printing web to which is applied a pair of spaced web registration tabs for each printing area. The web is fed into a printing station and during a registration portion of each printing cycle, is drawn against a pair of registration blades spaced to contact the tabs to provide longitudinal registration of the web with respect to the printing cylinder such that the web is skewed slightly. Lateral registration of the web is achieved by drawing the web to one side of the printing press until its edge is detected by sensing means. The screen frame carriage is registered with the print cylinder by a pair of adjustable stops on the carriage which contact the resiliently movable printing cylinder to assure predetermined alignment between the carriage and the print cylinder at the initiation of the printing portion of each cycle of operation. The continuous web can be fed through a plurality of such printing stations between which are interposed drying stations to provide multicolored prints.
