Outdoor laminates main function is to keep moisture away from the print. One way to do this is using a process called encapsulating. Encapsulating is basically 2 layers of laminate with the image sandwiched in between. Proper encapsulating is done with a small border so when it is trimmed, the edges will be completely sealed. The most effective way to get prints ready for the outdoor elements is using very specific laminates. Northco uses a vinyl substance called Calendered Pressure Sensitive Overlaminate® manufactured by Sihl. In the 3.5 mil thickness this laminate can withstand even the most severe weather.
