Abstract

A cushioning or damping layer is disposed between a flexographic printing plate and a printing cylinder or sleeve. The cushion layer is composed of an elastomeric material which has an open-cell relief surface which is sufficiently compressible to compensate for variations in printing materials and press conditions used during printing.
