One side of the sheet is printed with an ink (23) of the invention which has been diluted, as by a carrier to maintain pigment particles (25) in suspension whilst separating them to provide more clear matrix (26) through which illuminating light can pass and allowing more light to be reflected and pass down the substrate (24).
