Claim Text:
1. A method of monitoring the operation state of a printing system comprising (i) a real-world image forming apparatus configured to form ink image(s) on a real-world surface of a real-world rotating intermediate transfer member according to contents of an image database, (ii) a real-world substrate transport system defining a real-world substrate path and interacting with the intermediate transfer member at a real-world image transfer location where the formed ink images located on and rotating with the intermediate transfer member are transferred to a substrate, the method comprising: a. retrieving digital image representations from the image database; b. displaying simultaneously on a display device: c. operating a camera to acquire a video stream of a real-world location on the real-world substrate path as the real-world substrate, bearing ink image(s), moves along the substrate path through the real-world location on the real-world substrate path; and d. simultaneous with the displaying of the graphical representations of the intermediate transfer member and of the substrate transport system, displaying on the display screen the camera-acquired video stream of the real-world location through which the real-world substrate bearing ink image(s) moves, wherein the video stream is superimposed over the graphical representation of the substrate transport system in a location that corresponds, within the graphical representation of the substrate transport system, to the real-world location on the real-world substrate path.
