Substrates in sign making refers to the actual surface or product to which the graphics are applied. When producing your sign it is important to consider where the sign will be displayed, will it be an interior or exterior sign, and how long does it need to last. At NZ Sign Solutions we consider all the environmental factors and manufacture our signs to suit. There are a lot of different substrates for the manufacture of signs. We have attempted here to give a basic sense of what each of these materials is made of and what its best uses are.
