A tamper-evident vehicle registration plate comprises an opaque sheet 5 and a transparent plate 1 which are to be glued together. One of the opaque sheet 5 or transparent plate 1 has a surface on which characters 7 (such as letters, numbers or other indicia) are printed. An adhesive layer 11 bonds the printed surface 5 to the other sheet 1 but a region of that bonding 15a will have a weaker adhesive strength such that if the sheet 5 and plate 1 are separated the registration is defaced. The weaker region 15a can be a masking layer or release layer of a coated polymer film such as a PTFE, silicon, oil or wax basedsubstance, or a thermal transfer film. The adhesion of the printed characters 7 to their printable surface is weaker than the adhesion between the sheet 5 and the plate 1 so that the registration remains in a legible form on both parts of the registration plate.
