Interior support assembly and method for providing interior support to a target object being printed upon

摘要

A support assembly includes a lid, a plug body, and a conduit. The lid engages a target object having an exterior surface on which an image is to be printed. The plug body is disposed in an interior volume of the target object when the lid is engaged with the target object. The plug body engages an interior surface of the target object to form a sealed chamber inside the target object. The conduit extends through the lid to an orifice disposed between the lid and the plug body. The conduit delivers a pressurizing fluid into the sealed chamber in order to increase a pressure inside the sealed chamber in the target object. The pressure inside the sealed chamber provides a resistive force that prevents the exterior surface of the target object from changing shape when the image is printed on the exterior surface of the target object.
