As our most cost-effective imprint method, flexographic ink imprinting is available on many of our paper and plastic bags. Using a "flexible" photopolymer plate placed on a rotating drum, this method offers high-volume imprinting of your design. For intricate multi-color and four-color process imprinting using this method, contact our Design Centre custom team for more information. Please Note: Our imprinting processes operate in a post-production environment in which imprinting takes place on a bag which is already constructed. This means that some restrictions — such as a fold or a gusset in the bag — may impact its printability and available imprint area. In addition, because colors in a multi-color design are imprinted individually, a space requirement between these colors is necessary for best results. ColorVista is not subject to this space requirement.
