Zusammenfassung:A system for concurrent inkjet printing and defect inspection is provided. The system includes at least one print head adapted to deposit ink on a substrate, at least one imaging device adapted to scan the substrate, and a controller adapted to receive image data scanned by the imaging device during printing, determine if there are any printing defects on the substrate utilizing the processed image data, and transmit a control signal indicating a disposition of the substrate. The imaging device is adapted to scan the substrate during each print pass. Numerous other aspects are also disclosed.
