Abstract
The method includes printing a decorative design on a surface of a suitable support using a transferable ink; introducing this support into an injection mould in such a manner that, during injection, its surface carrying the decorative design faces the inside of the mould; and injecting into the mould a heated thermoplastics material for forming an object. To prevent the printed design from being deformed by molten thermoplastics material during injection, the method further includes introducing a separate film into the mould, before injection, in such a manner that it is applied against the surface of the support printed with the decorative design. The film is made of a material which bonds with the injected thermoplastics material and receives and retains the ink forming the decorative design, which separates from the support and deposits on the film during injection.
