Abstract: A device and method for coating and curing a protective layer on large format graphics comprises a roll-to-roll machine having a coat stage and a cure stage. A roll of printed web material turns about a load reel, passing through the coat stage and cure stage, and is wound around a finish reel. The load and finish reels may be driven by servo-motors. The coat stage comprises a coat pan which is partially filled with coating liquid and a Mayer bar for removing excess coating liquid. The cure stage comprises a light source and a plate. One or more devices, such as idler rollers, dancer rollers, stationary rollers, or load cells, are placed between the load and finish reels to control the path, tension, and speed of the web material.
