Abstract
A method of providing a vehicle roof glazing with a printed region having pre-determined optical and/or thermal characteristics is disclosed. Preferably, the glazing forms part of the roof the vehicle, for example, by being a windscreen that extends into the roof, or by being a rooflight or roof glazing system. The region is printed with an ink and the glazing fired, such that the printed region appears semi-opaque after firing. Preferably, the printed region has lower optical and/or thermal transmission characteristics than an unprinted region of the glazing. The pigment loading and/or pigment colour may be used to determine the optical and/or thermal characteristics of the printed region.
