Printing stencil and method for setting the relative position of a printed pattern and a substrate

摘要

The screen has reference marks comprising a luminescent material, and a reference mark opening filled with the luminescent material. An edge of the reference marks comprises predetermined distance to a reference mark structure of the printing screen. A relative position of a substrate (22) or a structure of the substrate to a reference edge of a transport system (27) is determined. Light from an annular illumination device (30) is radiated in a direction of the reference marks of the screen and is filtered. The substrate lines on a conveyor belt (23). Independent claims are also included for the following: (1) a method for setting a relative position of a printed pattern and a substrate (2) a screen printing station comprising a printing screen.
