The described method relates to the formation of a relief pattern on the surface of a shaped object such as a package or a security document by expansion of an inflatable ink. Said ink is applied on a support web and then dried, the printed support is varnished with a lacquer polymerizing under UV, and said support is coiled up. In a second step, said shaped object is manufactured and filled if a package is concerned, and its surface is irradiated, e.g. by a laser, in such a manner as to inflate locally the expanding ink printing, and said relief pattern is produced. <IMAGE>
