A system is disclosed that provides a compact printing system for applying images on the exterior of a clear or semi-transparent 3-dimensional object, such as for example a clear container like a wine bottle. The printing system includes a shuttle system for transporting a grouped parallel series of blank 3D media simultaneously into a printer portion of the system for parallel printing of media. The printer includes a series of printing tunnels that control a novel arrangement of print heads, pinning lamps, and a final cure lamp that minimizes or eliminates the chances for stray UV light to potentially impinge upon and foul inkjet printing heads used to express ink onto the surface of the 3D media. The arrangement allows for a higher degree of throughput of 3D media while avoiding the prior problems of the fouling of printheads during the printing of images on transparent or translucent media.
