摘要： The invention relates to a method for printing a digital image on a media object lying on a flatbed surface of a printer, the printer comprising a print head for ejecting recording material on the media object, a camera system connected to the control unit and positioned above the flatbed surface, and a control unit for storing a digital image and controlling the printing of the digital image on the media object, the media object having a contour as seen from a point of view of the camera system towards the flatbed surface, a first point having a position on the contour at a particular height with respect to the flatbed surface, and a second point being one of a point of normal projection of the first point on the flatbed surface and a point having another position on the contour than the first point, the second point being at the same height as the particular height of the first point, and the control unit storing a distance between the first point and the second point, the method comprising the steps of capturing a camera image of the flatbed surface by means of the camera system,determining a first image position in the camera image corresponding to the first point,determining a second image position in the camera image corresponding to the second point, deriving an actual position of the first point by means of the position of the camera system, the first image position, the second image position and the stored distance, and printing the digital image on the media object by ejecting recording material on the media object while taking into account the derived actual position of the first point on the flatbed surface.
