Abstract:
1. A method for operating a printing system to produce a printed pattern from a pattern layout, the printing system comprising a print head and a stage for supporting a substrate, the method comprising: separating the pattern layout into a plurality of design layers, a first one of the plurality of design layers comprising a first plurality of layout elements from the pattern layout, wherein the first plurality of layout elements run parallel to a first reference axis; performing a first print operation to print the first one of the plurality of design layers on the substrate by making a plurality of printing passes with the print head across the substrate in a first print direction, the first print direction being substantially aligned with the first reference axis; printing a plurality of alignment marks at predefined reference locations on the substrate; and performing a layer alignment operation between printing the first design layer and a second design layer, the layer alignment operation comprising:
