    Abstract: A stamp for patterning onto a receiving surface (103) of an object (101) according to a defined pattern (P) comprises a stamping surface (21) of a resilient diaphragm (20). The stamping surface (21) is planar at rest. The pattern (P) is reproduced on the stamping surface (21) and the diaphragm (20) is affixed to a rigid body (13) along a peripheral edge, so that a middle part of the diaphragm (20) can move along a direction perpendicular to the stamping surface (21). The diaphragm (20) is more flexible near the peripheral edge than in the middle part. Then, the pattern (P) printed on a pseudo-spherical receiving surface (103) using the stamp exhibits few distortion.

    Abstract: A method for printing a binary hologram on a manufactured product comprises the provision of a stamp with a pattern corresponding to the hologram (30). The product is initially coated with a metal layer. The stamp is inked with a masking solution (40) and pressed against the manufactured product (50). Then, the hologram print is obtained by selective etching of parts of the metal layer which are not masked (60). The method is adapted for printing holograms on optical lenses.
