Can you apply double sided lamination on large format posters?

Yes you can! There is no option for selecting double sided lamination online, but you can place your large format poster order and enter a note that you want double sided lamination in the "Got Comments" comments section (found on file upload screen - see visual below), and one of our 4OVER4.COM reps will add that option to your order and advise you as to the additional cost.
