For "Cold War Berlin" each panel will be effectively turned into a sticker before mounting to the gatorfoam substrate. The bottom layer is a pressure activated adhesive with a paper backing, while the top layer consists of a UV filtering matte lamination, which will protect the panels from fading and damage. The laminator was first webbed and adjusted to the proper tension, then checked for wrinkles, air bubbles etc. It is always good to do a test with a blank or duplicate.
Once your piece begins feeding through the rollers there's no adjusting, so make sure it is square with the feed tray and within the limits of the laminating materials. Our widest panel was 36" wide, and the laminator is 38", so there's little room for error. For an introduction into the world of large scale lamination, see here.
If possible, prepare multiple pieces and begin feeding them in as the one ahead comes through to avoid wasting laminating materials. Each piece must be brushed clean with a soft-hair brush to ensure that no dust/debris is trapped under the lamination. This can marr the professional appearance of your pieces.
Our 0.5" white gatorfoam substrate was prepped for mounting by painting the edges red to match our panel borders. Pieces of similar size were stacked and painted with a roller.
Panels were then stacked with small spacers and allowed to dry. Next, each panel will be thoroughly cleaned with a brush and tack cloth to remove and dust, debris or particles before the mounting begins.
