To make an underwater marker (40) with indicia on it, an uncured or partcured base material (3l) of one colour is prepared with the shape (32) of the desired indicia cut out of it. The indicia (30) are cut from uncured or partcured material of different colour and are fitted into the cut-out in the base material to form a single layer. A transfer material (36) bearing antifouling material (37) is placed over the face of the layer (30,3l) and the assembly is pressed together to embed the antifouling material (37) into the layer and to cure the contrasting materials (30,3l) together with each other and with an optionally underlying reinforcing layer (33). A backing sheet of the transfer material is stripped off to expose the particles. |
