Large format printing of banners can produce a stunning final product. Very large banners require the joining of two or more pieces of material by welding, stitching, or gluing. When welding two banner pieces together the type of ink used becomes an important consideration.
Solvent-based inks cannot be welded. The ink interrupts the bonding process. Instead, leave a margin unprinted on the banner the width of the required weld. Be sure to carefully align the pieces of material to make sure the final product is perfect.
Water-based inks can be welded without issue, no margin need be left when printing.
