Abstract:
1. A process for treating artefacts consisting essentially of the following steps in sequence: providing an envelop formed from a transfer support consisting essentially of a single layer of material coated with a pattern, wherein said envelope is adapted to receive the artefact; sucking air from an open end of said envelope to cause said transfer support to adhere to both sides of said artefact; transferring said pattern from said transfer support to both sides of said artefact by heating said artefact and said transfer support and applying pressure to said pattern in contact with said artefact; wherein said step of providing said envelope comprises forming said envelope from said transfer support so that said open end is defined by edge portions of said transfer support; wherein during said sucking step, said envelope is so arranged as to retain flexibility along its periphery, thereby allowing said pressure to be applied to said pattern directly by said transfer support; and wherein said envelop comprises an inner side contacting said object and an outer side contacting an external environment surrounding said envelope.
