ABSTRACT:
The disclosure relates to a device and a method for positioning a substrate to be printed in accordance with a screen printing method, lying on a print table, with respect to a template of a screen of the screen printing device. After placement and fixing of the substrate on the print table, and with the screen arranged close to the print position, the side of the screen towards the print table is illuminated from the print table and at least one predetermined edge section of the substrate is photoelectrically detected from the print table. After evaluation of the detection signals, the screen is adjusted into its desired disposition with respect to the actual disposition of the substrate, and then the printing is effected.
