ABSTRACT:
A plurality of curved plates which are adapted to be mounted on an embossing roll are identically engraved with an embossing pattern that matches the plate dimensions, permitting them to be interchanged or replaced without disrupting pattern discontinuity. In one embodiment, the pattern is created to match a given plate by laying out a skew grid matching plate corners, and using grid parallelograms as pattern unit cells. In another embodiment, an existing doubly periodic pattern is minimally distorted to match the plate geometry.
