A stamp for patterning onto a receiving surface of an object ( 101 ) according to a defined pattern (P) comprises a stamping surface ( 21 ) of a resilient diaphragm ( 20 ). The stamping surface is planar at rest. The pattern is reproduced on the stamping surface and the diaphragm is affixed to a rigid body ( 13 ) along a peripheral edge, so that a middle part of the diaphragm can move along a direction perpendicular to the stamping surface. 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. |
