ABSTRACT:
An embossing surface and a method for creating that surface is provided by a polyimide material which has photodefinable characteristics. One benefit is that the embossing surfaces do not have to be made by data transfer from the photo-definable surface. The polyimide material is cured by heating to a predetermined hardness appropriate for the surfaces to be embossed.
