Abstract
A machine head for producing a surface relief on a substrate, the machine head comprising a flexible stamping element having a curved profile and an inverse of the surface relief on its convex side; and the flexibility of the element being such that the inverse of the surface relief can be pressed to become flat and in planar contact with the substrate being pressed.
Claims12
A machine head for producing a surface relief on a substrate, the machine head comprising:
- a flexible element having a curved profile and an inverse of the surface relief on its convex side;
- and
- the flexibility of the element being such that the inverse of the surface relief can be pressed to become substantially flat and in substantially planar contact with the substrate being pressed.
A method for producing a surface relief on a substrate using a flexible element having a curved profile and an inverse of the surface relief on its convex side, the method comprising the steps of:
- bringing the convex side of the flexible element in to contact with the substrate;
- and
- flattening the profile of the flexible element such that the inverse of the surface relief is in substantially flat and substantially planar contact with the substrate.
