<p>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.</p> |
