Abstract: A digital lithography system prints a large-area electronic device by dividing the overall device printing process into a series of discrete feature printing sub-processes, where each feature printing sub-process involves printing both a predetermined portion (feature) of the device in a designated substrate area, and an associated test pattern in a designated test area that is remote from the feature. At the end of each feature printing sub-process, the test pattern is analyzed, e.g., using a camera and associated imaging system, to verify that the test pattern has been successfully printed. A primary ejector is used until an unsuccessfully printed test pattern is detected, at which time a secondary (reserve) ejector replaces the primary ejector and reprints the feature associated with the defective test pattern. When multiple printheads are used in parallel, analysis of the test pattern is used to efficiently identify the location of a defective ejector.
