A method for monitoring a printed image on a moving material web uses a camera to record the printed image. The recorded image is displayed on a monitor. A partial area of the printed image to be monitored is selected by means of an electronic control from an area of a virtual target image or the recorded image. The physical printed image recorded by the camera is stored in a memory and continually renewed on section-wise basis. The recorded image is renewed while the monitor displays a selected partial area of the printed image stored in the memory.
