20180093298 · 2018-04-05 · ·

A method for printing on a low surface energy substrate. The low surface energy substrates may be flexible low surface energy substrates. A primer is applied to the surface of the low surface energy substrate using a spray coating system. A pressure pot spray system that oscillates as the substrate passes underneath it on a conveyor system may be used. The primer is then allowed to air dry. Once dry, a printer can be used to print a graphic, design or other ornamental feature on the primed surface of the substrate. Once printing is complete, a clear coating is applied to the substrate and then cured.
