Polyester has greater tensile strength than does polycarbonate, which often allows it to withstand millions of actuations before fracturing. Also, polyester has a greater resistance to a broad range of chemicals. Polycarbonate is slightly easier to both print and emboss.Graphic Design and PreparationBlueprints Provide drawings that clearly dimension all physical characteristics including color breaks and copy.Colors Identify colors by using Pantone (PMS) color number or a color sample.
