A method for making an embossing device, said embossing device including, on an outer peripheral surface, a raised and recessed embossing pattern for reproduction on a planar and deformable substrate, the embossing device comprising a supporting cylinder and a crosslinked base resin layer disposed thereon, wherein a photopolymer coating is disposed on the crosslinked base resin layer, the method comprising the steps of:
- a) applying a material forming the photopolymer coating onto the crosslinked base resin layer disposed on the supporting cylinder while the supporting cylinder rotates,
- b) making uniform the thickness of the material applied to the supporting cylinder with a member, and
- c) exposing the photopolymer coating, through a mask, to light to make the raised and recessed embossing pattern in the photopolymer coating.
