Abstract: What is disclosed is a system for registering an object in a direct-to-object print system and a direct-to-object print system configured to operatively use various embodiments of the registration system of the present invention. In one embodiment, the marking system comprises a registration panel with a plurality of registration markings. A camera captures an image of the object in the object holder and the registration panel. A processor receives the image and analyzes the image to determine a position of the object relative to the markings on the registration panel. The processor determines whether the object is registered. If the object is registered, a controller causes the object holder to move the object past the printhead. Otherwise, if the object is not properly registered then the processor prevents the object from being printed and communicates a notification to a user that the object in the object holder is not registered.
