18oz banners provide excellent outdoor durability with enhanced wind resistance and mechanical tear resistance. Utilizing UV printing, they deliver high color saturation and high-precision graphic output due to the smooth surface. The optional white ink underbase process ensures vibrant patterns on dark backgrounds. The material is stiff, resists curling when hung, and offers a flat, professional appearance. It supports multiple installation methods: grommets & ropes, pole pockets, hook-and-loop fasteners, tie-down straps, etc. All sizes are customizable.
