Vehicle registration plates are manufactured by printing, or otherwise applying, multiple sets of alphanumeric characters to a transparent plastics panel and bonding a retroreflective backing sheet to the plastics panel, before cutting into individual number plates. The cutting step may be carried out by a laser cutter. The process has the advantage of avoiding a subsequent trimming step. It also provides a more effectively sealed registration plate.
