Trick...
I have a little trick for this. It might seem tedious but i can assure it works (at least for me).
I took one empty roll, then measured 10 ft (or whatever size you want to have your mark at) and rolled it in there. Then with a measuring tape measured the thickness of the rolled material. It came out to be like 5/8" (but might be different for your material, that's why you would have to do it yourself. Normally I do this with vinyl and banners (I don't really like to run out of while working). I'm not sure you can unroll and roll back the lamination material. Let me know if it works like this for you.
