Lamination is a thin (3mil) film layer that is applied on top of the printed surface of the mounted poster. It serves to prolong the life span of the mounted poster (protect against scratches, ink fading, etc) We do offer lamination as an option for the mounted poster product, however online you can select just our standard 3mil gloss lamination if you do want for the lamination to be matte and not glossy, please contact our Support Team at Support@4over4.com
