RoadScreen inks are perfect for temporary road works traffic signs complying with BS8442 or other international standards. This includes retroreflective temporary signs to the new Class Ref.1 (previously class 2) or Class Ref.2 (previously class 1). Class Ref.2 is the higher retroreflectivity standard and offers approximately 3 times the retroreflectivity of Class Ref.1, so is required for major carriageways in accordance with regulations.
