Abstract
To make a gravure cylinder, a metal cylinder is formed with recesses in its surface in a regular pattern and all of substantially the same depth, the recesses constituting gravure cells separated by cell walls. A different material, generally a plastics material, is then used to overfill the cells and the filled cylinder is subjected to the action of a surfacing tool, the operation of which is controlled not with reference to the axis of the cylinder but with reference to the cylindrical surface formed by the tops of the metal cell walls.
