I've laminated many matte-finish Epson prints, which gives them the look and DMAX of glossy. The main thing is to let the print dry thoroughly (at least 24 hours at normal room temperature/humidity, longer if colder/more humid) before lamination, or the lamination may not stick well. Longevity is at least as good as unlaminated prints, and laminated prints survive handling and spills much better.
