    introducing the coated substrate and the daughter stamp into a pouch that comprises an impermeable material;

    introducing the pouch and its contents into a hermetic vessel;

    evacuating air from the vessel until a pressure is at most equal to 0.5 bar;

    sealing the pouch, thereby obtaining a sealed pouch;

    reintroducing air into the vessel after sealing the pouch;

    introducing the sealed pouch and its contents into an autoclave;

    applying a pressure of between 0.5 and 8 bar and a temperature of between 25 and 400°
