My banner arrived with creases from being folded during shipping —

Folding oversized banners for shipping is standard practice across the large format printing industry. Carriers are optimizing package sizes, making odd-size shipments increasingly costly. To remove creases, hang the banner in a warm environment or lay it flat for several hours. For vinyl banners, you can carefully apply low heat with a steamer (do not iron directly). For polyester banners, light ironing on low heat is safe. The creases will typically relax on their own once the banner is hung and displayed.
